How “Perfect Black” Technology Works

The pixels produce the light in an OLED TV display. They can turn it off rather than relying on a backlight to do so on their behalf when they need to be dark. (Nick pino, 2009)

To be more detailed, Every TV has a self-lit system which sometimes hampers the picture contrast and color vibration. In that case, the black color is not the perfect black and the image on the screen can not give you something that an OLED could do. Like OLED technology is not the same as LED technology.

Pixels on OLED televisions emit light. On a TV, one pixel is made up of four OLED LEDs. 4 OLED LEDs are utilized to create a color cast in OLED TVs. It is traditionally red, green, and blue, with a fourth subpixel white for a brighter image. These four LEDs work together to create different color tints depending on the brightness. Four OLED LEDs make up one image pixel, which is one spot on the screen where a color cast is created.

To achieve complete darkness, the LEDs are turned off and no longer emit light. As a result, an OLED TV can produce a perfect black color. Due to manufacturing technology and operating principles, it is nearly impossible to obtain a perfectly black color in LED TVs. Some of the light emitted by the backlight passes through the pixels and is visible on the screen. When we turn off the LEDs in OLED TVs, we get the perfect black color. At the moment, only OLED TVs can display true black. (Sheridan, 2019)

Because each OLED pixel can cast its light source when needed and entirely turn off when black is required, viewers of LG’s OLED TVs do not experience light leaks, excess brightness, or erroneous colors. This “intelligent lighting approach” ensures that visuals are always crystal clear. You’ll feel completely involved in the digital environment that’s being displayed. The display is not only attractive to the eye, but it also exceeds the sense of realism that one could expect from a backlit LCD screen. (Jefferson, 2016). 

No Image Retention Problem

Some people think there might be a burn-in problem in an OLED TV. Burn-in, also known as image retention, occurs when an image or sequence is shown repeatedly on a television set, leaving a permanent trace on the panel, which is undesirable for home television. 

With screen saver features, a Screen Shift function that “moves the screen slightly at regular intervals to preserve image quality,” and “Logo Luminance Adjustment, which can detect static logos on the screen and reduce brightness to help decrease permanent image retention,” LG is working to reduce the risk of this happening in a greater way.  (Nick pino, 2009)
