    I've found several videos and articles that describe what this video describes, but I'm having trouble finding one that describes how a particular set of RGB voltage levels gets from the chip that is receiving the data stream to a paticular pixel on the screen. For a 1920 x 1600 pixel screen, that's over 3 million pixels! For each pixel, you have 3 LED's with 2 electrodes each that you have to wire up. So that's 3 million * 3 * 2 = 18 million wires! So I can't imagine that it's actually done with wires? How does it work?

    But how does the monitor send a signal to each pixel? does that mean each pixel is wired? I thought thats why mini led is hard to make,
    Found the answer from reddit, doesn't explain why the mini led is hard to make, and what kind of tiny wires are they using?:
    "ACTUAL ANSWER: most screens are subdivided into squares or columns of pixels. The actual pixels are made up of 3 subpixels. Yes, each subpixel has two wires going to it, usually one wire above going up and down and another line under the going sideways, like a grid with subpixels located at the intersections. Inside the screen there are "column driver" chips that take binary address along with color and intensity and convert it to a signal to drive the subpixels. If your monitor is say 1920x1080, you can have twenty 192x540 blocks each driven by their own driver. All these chips are then connected to the master chip that takes input from your videocard, does address conversion from x,y,intensity to column,x,y,intensity. This master chip has very few data lines coming from the videocard."

      That's a lot of information for 1920x1080 screen! You need about 50 million of 0's and 1's for each frame, if it was completely uncompressed.

    One thing I don’t get is how you get varying voltage from the binary? Binary is on and off so does each pixel use a digital-to-analogue converter in order to get the different voltages used to vary the brightness or are they just sent through different resistors depending on the binary numbers coming through?…

    • @Aboode007
      @Aboode007 10 років тому +2

      When there is light even when your screen is completely black that means there is still some degree of each color between 0 and lets say 20 or less so it's not completely black but it's very very dark that you would think it's black.

    Why do we need to stop twisting when we light was already horizontal ?

    • @InstrumentalCornerBest
      @InstrumentalCornerBest 8 років тому +7

      +Alex John In short, we need to stop twisting in order to make the light pass horizontal (and not twist to vertical), such that it is blocked and produces darker shades up to black.
      According to the video ( 1:34 ), the light gets twisted by default when no electricity is applied to the electrodes, and the liquid crystals are in their normal, twisted arrangements. Therefore, the horizontal polarized light (from the first polarizer filter) gets twisted to the vertical plane, passes through the second polarizer filter (the vertical one), resulting in a lighted sub-pixel (one LC with the the color filter at the end).
      When the electricity is applied to the electrodes, the liquid crystals lose their twisted or "normal" arrangements and are all arranged horizontally, simply passing the incoming horizontal light forward, which then gets blocked by the vertical polarizer filter, resulting in a black pixel or color filter.

    I was playing around with a toy microscope and noticed these rgb bars in the pixels and I assumed it either just switches on or off. I thought the brightness would stay uniform through out depending of the brightness setting. I had no idea even at a fixed brightness the brightness of each pixels' rgb would also play. I cannot begin to understand how they are even made. I mean we always assume oh it's machine, but how? these components are so small. It's fascinating how common this technology has become when you realise how much is going on for something so simple.

    But I have another thing I am curious about. Why put up a horizontal polariser if you need to make the light vertical? Why not just put vertical polarisers right in front of the backlight? Why would you go through all of this LC stuff if you could just put up a vertical polariser at the start?

    • @sidewaysfcs0718
      @sidewaysfcs0718 7 років тому

      the idea is to switch between a bright state and a dark state.
      when the liquid crystal is subjected to an electrical field, it looses its twist angle, therefore losing its ability to twist the polarization of light.
      so you exploit crossed polarizers, between crossed polarizers all light is blocked unless you have some kind of material in between that can switch the polarization of light.

  • @subjectlife82

    1 0 1 0 0 1 0 1
    for each bit you get 2 possibilities : 0 or 1

  • @zdmoz88

    One question. Before putting vertically etched glass and horizontally etched glass, liquid crystals (LC) are randomly oriented. After putting them in front and rear of LCs, LCs align with the etched pattern. So the single LC closest to the front glass is perfectly 90 degrees apart to the other closest to the rear glass. How come LCs follow etched pattern in glass and why?

    • @BallstinkBaron
      @BallstinkBaron 9 років тому

      I think he said it's because the electrodes placed in the etches have currents run through them that reorient the crystals.

    • @sidewaysfcs0718
      @sidewaysfcs0718 7 років тому

      no they do not. the etched glass actually favourises a planar arrangement of molecules.
      Either etched glass, or glass with a layer of oriented polymer will do the same thing, the molecules simply follow the features of the glass.
      Also, this video has a small mistake, the liquid crystal is never disordered in the liquid crystalline phase, and it's in that phase in a wide temperature range, prefferably from ~0 C all the way to 60-70 C, otherwise the liqud crystals would transform into an isotropic phase at higher temperature, or even crystallise into a solid state at lower temperature.
      The liquid crystalline phase is already ordered in itself, most likely into a chiral phase, but this chiral phase would have the helixes in different arrangements in the glass if it's not etched or covered in polymer.
      The transparent electrodes are Indium-Tin-oxide and are needed to change the liquid crystals orientation and destroy the helix structure, this requires an electrical field.

    Now i just need to figure out how they manage to send the electrodes into these things seperatly. It's honestly really fascinating ów0
    Or aleast it is when you speculate on how you can use this science to create something like an omnitrix or another scienctifical tool of amusement.

    If a computer display is set at 60 FPS, does that mean that 60 times per second the computer adjusts the amount of light going to the red, green, and blue pixel?

      John Doe The computer display is measured it Hz by the way, so it's technically a 60hz monitor. It has the capability to refresh up to 60 times a second, so when playing a game, if you are getting more than 60fps, you would be using more processing power than needed. There is no point in getting 90fps if your monitor will only refresh 60 times a second

      +Cr1spyBacon8r Actually, FPS isn't an end-all way to determine if you are getting enough frames. There can be a lot of screen tearing going on, or differences in times between frames that are all too visible to the human eye. All too often, 60fps rounded by the second isn't as smooth as it could possibly be, and a higher processor capability can help greatly in remedying that issue. You're %75 right though, sometimes it is a bit of a waste.

    and how does it control the amount of light that passes the filters ? this is my question :(

    Thanks for this. This video explains it a lot better about LCD. Does this apply to IPS and Retina displays as well?

    • @gyroesehni
      @gyroesehni 8 років тому +1

      Trinispace A retina display is just a high-density display. IPS I believe has 2 sets of polarizers and liquid crystals for deeper blacks and richer colors

    I got my eye very close to a computer and i saw the colours on the pixels (they were REALLY small). For some reason I saw red, yellow and black
