As a computer gamer, we often hear the term TFT LCD. But do you know the composition of a TFT LCD display? Today, we will introduce you to the details of TFT LCD display panels parts.

What is a TFT LCD display?

First, let’s understand the basic knowledge of TFT LCD display. TFT, short for “Thin Film Transistor,” is a liquid crystal display made of thin film transistor technology. It has the advantages of high brightness, high contrast and low power consumption.

Composition of TFT LCD display panel

The TFT LCD display panel consists of the following parts:

Backlight module: The backlight module is one of the most basic components of the display, which provides the brightness of the display. At present, the most commonly used backlight module is LED backlight module.

Front glass: Front glass is the housing of the monitor, usually using tempered glass. It can not only protect the monitor, but also improve the compression performance of the monitor.

Liquid crystal layer: The liquid crystal layer is a key part of the display, it is responsible for controlling the arrangement of liquid crystal molecules, so as to achieve the display image output.

Filters: Filters are mainly used to adjust the color and brightness of the display.

Drive circuit board: The drive circuit board is the input signal into the control of the LCD layer of electrical signals, in order to display the corresponding image on the monitor screen.

The working principle of panel parts of TFT LCD display

TFT LCD displays work by controlling how liquid crystal molecules are arranged in the liquid crystal layer, thereby controlling the brightness and color of the pixels. Liquid crystal molecules can rotate at different angles under different electric fields, changing the transparency and color of the pixels.

When the driving circuit board sends an electrical signal to the liquid crystal layer, the liquid crystal molecules rotate under the action of an electric field, which controls the brightness and color of the pixels. Eventually, through the filter and the front glass, we can see the image appear on the display screen.

Advantages and disadvantages of TFT LCD display panel parts

Next, let’s look at the advantages and disadvantages of TFT LCD panel parts.

advantage

Good display effect: TFT LCD display panel with high brightness, high contrast and wide color gamut, can present very fine image.

Low Energy consumption: TFT LCD display panels use liquid crystal display technology, which provides much lower energy consumption than traditional displays.

Wide viewing Angle: The TFT LCD panel has a wide viewing Angle, allowing users to view the images on the screen from different angles.

Small size: TFT LCD display panels are thinner and lighter than traditional displays and take up less space.

shortcomings

Slow display speed: The response speed of the TFT LCD display panel is slow, and there may be some lag for some applications that require high display speed.

High price: The price of TFT LCD display panels is relatively high, especially high resolution, large screen products.

Angle discoloration: TFT LCD display panel may have color distortion, black blue and other problems under different viewing angles.

summarize

The above is a detailed introduction to the panel parts of TFT LCD display. As a computer player, it’s important to know the basics. With an in-depth understanding of the panel parts of TFT LCD displays, we can better understand the structure and working principle of the displays, so as to better choose and use the display products.
