The difference of LCD main body
- Time：2021/4/9Source：Shenzhen Kaixian Technology Co., Ltd.
- The speed at which each pixel of LCD reacts to the input signal, that is, the speed at which the screen changes from dark to light or from light to dark. The smaller the response time is, the user will not feel the tail dragging when watching the motion picture.
LCD 1. Different main body
1. LCD screen: it is a display device composed of LED array.
2. Touch screen: it is a kind of inductive liquid crystal display device which can receive the input signal of contact
3. Open circuit: the customer calls it "missing stroke, missing stroke, broken word". In fact, it is the ITO that is scratched and disconnected, and what is seen on the module is also missing stroke.
4. Insufficient etching: customers call it black spot or multi-point, and there is one more pattern on the module or electric measuring machine.
5. Etching transition: it is called word thinning and word deformation by the customer, and a part of a byte displayed on the module or electrical testing machine is missing.
6. Word light: refers to the higher Voff voltage. Customers generally call it word light and color light. It can be divided into two types (1) local word light: caused by high current; 2) local word light: caused by high current;.
2、 Different characteristics
1. LCD screen: liquid crystal is placed between two pieces of parallel glass. There are many vertical and horizontal small wires between the two pieces of glass. Through the power on or not, the rod crystal molecules can be controlled to change the direction and refract the light to produce a picture.
2. A display is also commonly referred to as a monitor. The monitor is the I / O device of the computer, that is, the I / O device. It is a display tool that displays certain electronic documents on the screen through a specific transmission device, and then reflects them 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.
After passing through the first polarization filter layer, the light from the LCD backlight enters the liquid crystal layer containing thousands of liquid crystal droplets. The droplets in the liquid crystal layer are all contained in the small cell structure. One or more cells form a pixel on the screen. After straightening, the liquid crystal molecules change the angle of light passing through them, so that the direction of light does not match the direction of the top polarization filter. As a result, no light can pass through this particular area of the LCD, which is darker than the surrounding area.
