P3.91 LED Display

LED display technology P3.91 Led display

Light Emitting Diode (LED) display technology is in a fascinating stage now. The evolution of the display technology started with the cathode ray tube to cutting-edge OLED technology. Even though the OLED displays are superior, P3.91 LED Display still hold a market share of around 40%. Scientists continue to create strides in improving the LED technology and soon it could once again end up being the king next few years. In this informative article, I'll explain how this display technology works and what the long

Experiment on single pixel

Really a big pixel, with three input LEDs; red, green and blue (R, G and B). So, If I take this pixel, reduce its size and replicate many such pixels, I will make any LED display.

How does the display work?

The quality of the image will improve if I reduce the size of all the LEDs.

So, how can scientists overcome this issue? Instead of creating extremely small RGB LEDs, they used miniature color filters for the display and used normal-sized white LEDs as a backlight. Arrangement of two polariser sheets and a product that could change the optical angle .

Light intensity control mechanism

Now, let's understand the light intensity controlling mechanism.When the backlight incident on a straight polarizer, it allows only the vertical part of light to pass, blocking out other components.The role of the optical sheet now makes play.When I give a rotate signal to this sheet, it'll rotate the vertically polarized light to the angle I want. If this angle of rotation is 90 degrees, the next polarizer layer, the horizontal polarizer, allows the light to feed completely If I rotate the light significantly less than 90 degrees, the horizontal polarizer will block out a number of the light, and the intensity of the subpixel will be reduced. If the angle of rotation is 0 degrees, obviously the complete light will be blocked This is actually the way I can control Each subpixel's light intensity.

Using three such units, I can construct a pixel. Now I can obtain any color pixel by simply varying the angle of light rotation. To obtain a cyan color, I merely have to block the red filter light. I can build a whole display system. . .

Construction of LED lights

Let's return to our LED display design which remains incomplete.Some pixels are brighter than others as the backlight LED arrays are providing uneven light. With the help of diffuser sheets, I can evenly spread the light. prism sheet concentrates light in a forward direction. This is actually the actual construction of the LED display as shown in.

Future of LED Display technology

As I've explained earlier, the manufacturing of small LEDs is difficult, however not impossible. Scientists are attempting to overcome those problems by developing new manufacturing methods. Micro-LED. OLED, the organic layer degrades with enough time which in turn causes pixel burn-in issues. Micro P3.91 Led display are obviously more durable as a result of usage of Inorganic semiconductors. LEDs are inorganic in nature, they have a better brightness than organic technology. Currently, Samsung is the leading manufacturer of Micro-LED displays.
