The speed at which each pixel of the liquid crystal display reacts to the input signal, that is, the speed at which the screen turns from dark to bright or from bright to dark. The shorter the response time is, the user will not feel the drag of the trailing shadow when watching the motion picture LCD Display Module.

LCD screen one, the main body is different 0.42-1.3 inch OLED

1. LCD screen: It is a display device composed of light-emitting diodes.

2. Touch screen: It is a kind of inductive liquid crystal display device LCD screen that can receive input signals such as contacts TFT LCD.
3. Open circuit: customers call this as undercutting, missing line, or hyphenation. In fact, the ITO is scratched and disconnected, and the missing line is also seen on the module.

4. Insufficient etching: customers call it black dots, multiple dots, and there is an extra pattern on the module or electrical measuring machine TFT LCD module.

5. Etching transition: customers call it thin, deformed, and the display on the module or electrical measuring machine is a part of a byte missing Transparent OLED.

6. Faint word: refers to the higher Voff voltage. Customers generally call the word thin and light color; there are two types (1＠ local word light: caused by large current;

  Two, the characteristics are different

1. LCD screen: liquid crystals are placed between two parallel pieces of glass. There are many small vertical and horizontal wires between the two pieces of glass. The rod-shaped crystal molecules can be controlled to change the direction and refract the light to produce the picture. .

2. The display is usually also called a monitor. The monitor is an I/O device belonging to the computer, that is, an input and output device. It is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. According to the different manufacturing materials, it can be divided into: cathode ray tube display (CRT), plasma display PDP, liquid crystal display LCD and so on.

  The light emitted from the backlight of the liquid crystal display enters the liquid crystal layer containing thousands of liquid crystal droplets after passing through the first polarizing filter layer. The liquid droplets in the liquid crystal layer are all contained in a small cell structure. One or more cells form a pixel on the screen. The straightened liquid crystal molecules change the angle at which light passes through them, so that the direction of light and The orientation of the top polarizing filter no longer matches. Therefore, no light can pass through this specific area on the LCD, which is darker than the surrounding area.
