we are the best in operational performance, we are not inferior in sports competitions, and in general, in the life of peoples, we are doing an important thing, protecting public order. participants of the parade laid flowers at the monument to the liberators as a token of gratitude for the great victory. the procession ended with a solemn rally in the building of the internal affairs directorate , the distinguished employees were awarded awards and regular titles for working in modern agro-industrial complexes, it is necessary to attract more young specialists. this was emphasized by the chairman of the chamber representatives of the national assembly of belarus vladimir andrechenko. during communication with students and teachers of glubokoe state college. one of his profiles, agricultural training , is being introduced. hi-tech. there is a center for precision farming, training is organized, including for specialists from the agro-industrial association. we are so modern, despite the fact that they are still at

such a young age. they still try to make a lot of them. the length of our country. who is in what? maybe someone killed someone in sports public? and they should be responsible citizens of our country and, most importantly , patriots. vladimir andrechenko also held a field trip today. reception. questions different asphalting roads rural areas electric heating equipment in private homes. people also came with gratitude for the prompt resolution of issues raised at previous receptions, in particular for assistance in the overhaul of an apartment building in the district center. by this time i have all the next issue 19:00 see you.

it is present in almost every home today. a even in school offices and in the offices of workers, we are so used to it that sometimes we don’t even notice how we literally turn it on automatically. sometimes it’s just for the background, but at the moment i really hope that it ’s not working for you in the background, but turned on, because you definitely want to become a little closer to science on the air for the next half hour, a science project near the ekaterina beretskaya studio. hello. and today, literally by scientific parts, we will analyze the tv. i strongly recommend not to switch, at least in order to find out who and when gave us the opportunity to control the tv without getting up from the couch. we will also tell you how the remote control works. and here's something else. what did

the first tv and the first remote control look like? a miracle of technology or simple physics, let's figure out how bright and voluminous images appear on a flat screen? and we will study in detail the first belarusian transparent tv. well, let's start at the beginning, that is, with the history of the issue and people who are somehow involved in the appearance of television in a person's life. about who was the first on this issue has not subsided so far,

well, in most sources, the starting point of television history is called 1875, when george kerry presented the first prototype of a tv set, a mosaic structure consisting of gas discharge tubes. although if, as they say , to dig deeper, then the inventor of the camera obscura turned light into an optical pattern even in the middle ages, but with the discovery of a chemical element. selenium made it possible to turn light into electricity, but let's get back closer to our time. and here it is almost unanimously sounds less than the german inventor paul nobody, who introduced the world in 1884. a unique technology for obtaining images of transferring it to the screen using a special disk, from which information was considered. a few years later , a scottish engineer. johnbert, taking as a basis the development of a small one, invented the world's first television receiver. the device was quite small . it worked without sound, but the picture was quite clear. but the first device

more or less similar to our tv appeared at the end of the twenties of the last century, thanks to the talent of the russian engineer vladimir zvarykin, it was he who created a high-vacuum receiving tube with a mosaic photosensitive structure, calling it an iconoscope. by the way, the name kinescope, which is more familiar to us, also belongs to zvara. cinema by the mid -thirties of the twentieth century, the inventor had improved the television system so much that a stable image in television receivers could be obtained using an iconoscope with a multi-stage electron multiplier in 1936 on television with three the opening ceremony of the berlin olympics was broadcast by television cameras and after 3 years the television system from vara and the cinema were presented at the new york industrial exhibition and now i propose to understand

the technology itself and understand how we generally see a three-dimensional picture on a flat screen with us in touch associate professor department of nuclear physics of the faculty of physics of belgos state university sergey sergeevich good afternoon. explain to us the magic of television. hello ekaterina. thank you for such a question. it implies a very interesting detailed the answer is that the most important thing in a classic primitive cathode ray tube, or as it is also called a kinescope, we have a certain screen, which is a glass coated with a phosphor phosphor. in this case, this substance is ordinary gray or white, which, starting to glow in the place where the electron beam hits, in order to organize this beam , a special device is created that emits our electrons, and then with the help of special

electrical systems. we can change the motion of this beam, and it can hit or here or here, anywhere, that is, if we apply a certain voltage to the beam, it will simply run around the screen and draw lines. well from this. before the tv , we will modulate one step, that is , change the intensity of this beam and the glow will be different, that is, brighter darker. in addition, we can move it not only in one plane, but also in the second one, since our screen is two-dimensional, that is, of course, no one wanted to stop there, firstly. uh, wanted to see a color image. the solution was quite simple.

it would seem that it is enough for us to have three nearby red green blue points in order to get, in principle, a point of any color, that is, the only thing left is to put just such points on our screen and then force our beam to give the right places with the right intensity. the first color televisions. they were beautiful and bright, but their colors did not match. so, could the football player have a red face, but a rosov shirt, or vice versa? in general, uh, but the picture already attracted then, then new new developments began. screen clarity improved the picture became more accurate , the resolution of the picture increased. that is, it was possible to look at smaller details, then they learned how to make a flat screen. the second generation of tvs. this is a plasma tv.

in which tvs, firstly, an electron beam is not needed, only a flat screen is needed, which consists of small cells, again, these triads of three colors, each of them contains its own gas, which, when voltage is applied to it, glows with its own color. basically, the plasma tv made a breakthrough in the creation of flat and large tvs, but you yourself understand nothing stands still in simple words, what is liquid crystals, inhabitants of crystals - this is a kind of substance that consists of long molecules. and this is a molecule under the influence of an electric field, can rotate. oriented by a weak electric field, but apart from the fact that it simply rotates in space. it changes the parameters of the light beam that passes through the cell or, in our case, the screen filled with liquid crystal. and this is where technology has become

to plant by leaps and bounds now leds have come to replace them, so that, firstly, it will increase the operating time of our screens, increase the brightness , and generally increase the quality of work. well , of course, probably, the consumption of the tv. it is a semiconductor device that emits light. its dimensions can be made practically. um, how far does technology allow you down to nanometers? and of course, we can simply dial the screen from the leds, the latest most used conductor devices are organic leds. these are leds built on based on organic substances that allow us, firstly, to reduce the cost of the process , to reduce the size, to increase,

the resolution of the screen, and plus, there are such interesting possibilities that flashed in all the news feeds a couple of weeks ago. this is the creation of transparent tvs with a picture , everything is clear. thanks a lot. but today the tv is without another device. we have no idea how to joke the older generation. although more recently, the function of this device in the family was performed by one of the members families. of course, i'm talking about the remote control sergey sergeevich, this is also a science. yes , indeed, the first remote control was on the wires. in my life i never held such hands in my hands, i read a lot about them , but i was so lucky that this summer i decided to make up for the lack of my youth and bought an old, almost dead elektronika 004 soviet tape recorder, which provided for this wired remote control. there's a big remote connector on the back - it was

just a set of buttons that switched via relay wires on the device itself. uh, also switching systems for televisions also worked. they were no different, but, of course, everything does not stand still; the first remote controls that appeared were arranged in the usual way as a box. here is a speaker that beeps. ultrasound and here the ultrasound control circuit contained commands that were received by a microphone on the tv, then there was a decryption system that decoded the signal and switched on the tv. naturally. this system was unstable next step is creation of a remote control on infrared leds, when instead of ultrasound we use light, infrared, that is, this is a range that we cannot see. this 0.8 micrometer device is the same as all

modern tvs are so -called smart tvs. that is, it is a sufficiently powerful computer with a complete set of necessary devices and properties that are in our computer, namely, they necessarily have e-wi-fi communications over long distances. well, to access the internet. as well as bluetooth communication - this is radio communication on small distances. so here are the modern consoles. what is the name of the team precisely over the bluetooth radio channel? what allows, among other things, using a regular smartphone and a simple application to also control the tv, because this is a standardized unified system, everything is very simple. why is it expensive for me? because when i figured out how my tape recorder works with the help of my comrades, i soldered everything

that was there for remote control , put a photo, a diode and a microprocessor. and now i have a tape recorder. this remote control, like the most modern tv or other device. that 's it sergey sergeevich thank you very much. and i will add that the american robert eiler invented the remote control in 1956, for which he received an award from the american academy of television. in our project, we will show you unique personalities. i knew that i am an internally normal fighting girl who is not afraid of change, is not afraid to change her life for something. he looked at how i was training. he says, i have not seen this, he says, well, my daughter is in sports for many years, but i have not seen such a warm-up, nor such a movement, nor such an approach that they break stereotypes with an example and

their own experience. last step. here in life. they are coming towards you. moreover, we noticed a pattern, of course, really big people are big with a desire to lose weight, of course, which i constantly encounter. and with what is not. this may not work. we may not trust you. i always say, try watching the program to break the stereotypes on belarus 24 tv channel. we are working to ensure that you receive the latest useful information 20 the minute format allows us to talk about what is happening in belarus and gelding with objective facts about a healthy lifestyle. offer projects and films that will definitely become your favorites, they are good. and we achieve peace-loving ones as a result of selection.

oh my god those little bees. need to keep even families with children this and more. the project is waiting for you on air 24/7, watch on belarus 24 tv channel . on the air, the popular science project science is nearby today, we are sorting out the tv in scientific parts. and here's what we'll talk about further. fantasy that can be viewed live the creators of a transparent tv under the brand how much does it cost and we will analyze the most

popular tv model in parts. but how modern tvs are produced will already be told by my colleagues in the section how is it done? it only takes 22 seconds for a new tv to come off. from the assembly line. perhaps this was due to the fact that in different areas of production , almost all components are also quickly created in a matter of minutes in advance by almost 70%. domestic liquid crystal televisions are composed of belarusian components, the remaining 30 are parts that are produced in only three countries of the world and there is simply no point in creating them yourself. the birth

of a new tv set in a software research center and then, despite its modest dimensions, the main part of the device, the board , takes just a few minutes to complete. now we are in the pcb production area, so we have two types of production. this automated manual board is the brains of the tv. and after board production. at this site, these tv brains fall into further mass production. the main, well-thought-out

production system per day, workers create 12,000 boards. after all, we are on soldering, which are designed to automate the installation of output radioelements . the main advantage of these installations is to improve the quality of products, as well as increase labor productivity in general. at the same time, specialists in other areas produce other components. lcd panel consists of led backlight lcd matrix sheets of brightness conversion diffuser frame, all of this is installed in a metal casing. they create an led backlight module on the smd installation line in the so-called clean room of the eighth grade, while such a room is the only one in our country where not a single speck should fall, otherwise there will be a marriage.

various equipment is used for the production of lcd panels. for example, a screen printing printer, solder paste is applied to the printed circuit board on it. after that the fee enters the automatic, installer. here the smd components are installed, the printed circuit board is installed. after that, the board enters the infectious melting furnace. it is placed on the display module to the case, then it is fixed with a board and a cable is connected immediately after that, the image of the lcd panel is tested, then the so-called diffuser comes, and then three led modules are placed on the basis of the panel and fixed with screws , solder paste is applied to the printed circuit board blank , leds are installed, and , then all goes to the oven. a few more production stages again testing and working out what is in the course of the production cycle. it turned out, according to experts , there is another part of poor quality, which

is produced at the factory and without which it is impossible to assemble a tv. this metal casing sheet of metal automatically falls under the press and in seconds the master takes out the finished part. and finally, when everything is ready, the future tv is waiting for the conveyor. we are located in one conveyor of our enterprise, where the assembly of all components into final products familiar to the consumer, that is , directly into the finished tv , takes place according to the technical processor developed for certain models. our technical process contains about 50 operations , depending on the design of the tv , includes the assembly of all elements, then testing. and as always

, testing is given special attention. as part of our holding, we have our own certified test center , we carry out more than 50 different tests. this concerns both television equipment and any other products of the holding. more than two million tvs a year leave the assembly lines of the enterprise - this is more than 400 new models. all products comply with international standards, and the share of innovative products in the total volume is more than 98%, as the top management of the plant admits, all their ideas in the field of innovation are implemented under the strict guidance of the holding's management company. this is a show in

which there is humor excitement and dexterity, so that it is not excruciatingly painful and ashamed of lived years. it is better to be in our program the audience, let it be. yes, god knows, you studied latin, right. well, yes, we had the first six months of latin, but it was a long time ago and not true. this is how two teams will compete for the main prize and the title of being the best, that is, the circumference of the circle is 200 m. you can’t eat it. no matter what 200 m -1 is the answer correct or not, we will find out in the intellectual entertainment project tower on our tv channel. we educate

first, not the warrior we educate a full-fledged citizen of our society, how to maintain a balance between the state and each individual in order to defend the interests of their voters, so when you are betrayed, it’s the same as your hands are punched. you can, but there is no hug. in my opinion, the more control, the better the steering wheel of fate you try in these situations. you become stronger. you already look differently at certain things to save your heart again. and conscientiously go about my business 2 i will always pray for every child in our country and in the countries of all, probably all countries of the world, let's talk about the values ​​of friendship, happiness, and plans for the future in the program say, don't

be silent. watch new releases on belarus 24 tv channel. we will talk about a completely new technology for creating displays. our guests are representatives of the holding, where alexander andreevna mikhailovich, the intellectual first transparent tv set, developed and assembled and presented at the exhibition of belarus, hello. this is a small marketing ploy tv is built on the basis of the transparent substrate is located at a distance from each other, due to which

the image of a partial picture behind the screen is quite popular today, that is, the smartphone watch model uses led screens. it's not like the story is new. yes , but not the most competitors, well, it is new in terms of a transparent screen, one of the few first solutions for a transparent screen. how the idea arose, we looked at foreign experience and decided that we needed our belarusian transparent tv or in some other way i’ll tell you a little about us. tv for us traditional is the key product and we keep a close eye on all the new ones. that is, it is first a kinescope on tvs flat-screen tvs 4k smart tvs. mini years tvs laser tvs are eight cards, that is, not all of this went into series, but traditionally samples of all technologies at the plant were mastered, and when at the end of the nineteenth year a river came into the world community of professional

tv manufacturers about the possibility of creating a transparent one, we naturally also connected and started working. it was rather lengthy process, but today we are ready to provide practically. and a finished serial product. it seems to me that a couple of years for such a product. here it is on our screen, but it seems to me that it worked quite a bit ourselves. did the scientists from the academy of sciences help someone? tv is not the most innovative product, so they did it themselves. let's talk about design, it's just soaring at the exhibition. yes, it was also conceived this way or due to the own technology of alette. eh, like this it turns out. you probably noticed that at the exhibition he survived just a storm of emotions among visitors. and we noticed that there really is a huge interest, of course, its key highlight was that it would create in out, attracting attention. and we succeeded. he has several performances. that is, it can e be attached to the ceiling, then it

attracts attention. yes, and it floats, it can also be, uh, a desktop version and also mobile mobiles can be installed on a rack, that is, how is an interactive system good, and what about functions? well, you know, life today is functional, everything should be to the maximum, and the same as in our usual opaque tv. yes of course, it can be used as a regular smart tv and also as a commercial display. uh, then already a cloud-based content management system. that is, you can run there absolutely any of your presentation video photo text information logo, that is, it all depends on the purpose of e and instead of using it. but it's not serial. ah, so far the story. yes it prototype. how expensive in general and, well, in the future, uh, we will go into the series. yes of course, you probably noticed by now. it is more like this, a fashion model of production is already on sale, so far, of course, under

an individual order for legal entities. however, after our beautiful exhibition, it was very intellectual. we noticed just a huge demand and even uh our population would like to have such a tv in every house, and therefore now our specialists are actively working on marketing research. and perhaps in the near future it will be true and we will bring the future a little closer to every home. but they say that these are the panels. yes, well, if i express myself correctly, you can even use it in cars. tell us how it is generally one of the main areas of application of such a screen is commercial, that is, not everyone is at home. you may need transparency, or in order to look at your wallpaper behind the wall, we saw pilot projects in hong kong and moscow for similar technologies. a transparent screen was built into the window of the car meter, when the train moves in tula , advertising content and information about the route are displayed there, and at the station the screen turns off and becomes transparent and the passenger sees the platform. perhaps a similar pilot

project. we implement minsk are going to amaze with what kind of tvs? what can be in development, maybe with someone in cooperation? that is, now we are working on round screens, that is, also formatted for commercial use. well, it is unlikely to be a tv, but nevertheless , ultra-wide screens and in the early stages. we are starting to work with flexible displays quite an interesting thing the opportunity for some kind of wearable electronics, it’s too early to say, but who knows, maybe in a couple of years we’ll bring it to you at the next exhibition of belarus intellectual in a few days, around the cities for now now , well, i’m with our exhibits , and next year we will plan something new to follow the new horizons, be sure to thank you, it was great. very interesting. really. thank you for surprising and successful new developments to you. thank you too. okay thanks for inviting me. nice to meet you.
