What is all about an LCD Display is a discreet manner?

These liquid crystals do not emit light rather it uses backlight or reflector to produce images in color, and hence they are visible to human eyes.

The LCD display module works basically on producing backlight evenly on the small rectangular shaped subsection called as Pixels.

The light falls on the pixels and dims away, later passes on to different color filters. This is how a small portion of a solid color becomes a subpixel. And those subpixels are lined up in a group to form high-intensity display look colorful and a variety of colors follow the pattern that makes the LCD display flawless with millions of patterns and displays.

The smoothness of a display complete depends on the number of comprised subsections or pixels, the smaller rectangular pixels are added, the better will the LCD display.

To understand the complete procession of how the LCD display module works, you need to know about the following four elements:

1. Panel

Firstly, the part of the LCD display that dims the pixels is the Panel. It’s a piece of grey glass, which is also known as polymer sheet in technical terminology.

There are various methods to the dim the passing light although. One of them is a piezo-electronic layer, in this is a layer somehow blinds the pixels by covering them and dims the light.

Another way is to use opacity or aperture modulation, in this method an element works as an obstacle, to keep pixel away and make dimming possible.

But the most commonly used method today is polarization method. When the light direction is being rotated from its usual position, polarization happens.

This way, the light falls on the pixels only in a certain angle position, which is how polarizing filter works. And those filter there are liquid crystals, which have the quality to bend light. This process starts with one and passed on to another.

2. Backlight

In LCD display, the source light is backlight; it has to be only white. The light turns into different colors like red, green and blue in the later stage.

The source of wilt light is mostly CCFLs and LEDs, CCFLs are competent to produce fluorescent light by using mercury, whereas LEDs do not use any mercury at all.

Also, to make that light spread Diffusers and reflectors are used. 

3. Power supply

To take the process further, you need voltage to lighten up the LCD display for which power converter is required.

The power converter converts the intermediate DC voltage (12-24V). The first part of converted powers goes into 36-80v for LED backlights and the other part of 5v is used for microelectronics make the LCD display look smooth.

4. Micro-electronics

They are involved in signal processing and works in two parts, the video signal receiver and the panel driver, which makes the final display possible.
