LCD screen black and white display mode and link mode? Do a lot of people not understand what that means? Then do not know how to do, sometimes fumbling, leading to unnecessary trouble, but there is nothing to worry about. Next, I will introduce you to the black and white display mode and link mode of the LCD screen, so that you have more understanding of this aspect. I believe you will see the harvest!
What are the display modes of the black and white LCD screen?
LCD black and white screen is divided into: TN, HTN, STN, FSTN, DFSTN, VA, etc. By product type.
LCD black and white screen according to the display mode is divided into reflection, semi-transmission and full transmission.
1. A reflective LCD has a reflective plate added behind the bottom polarizer, which is usually used outdoors and in well-lit offices.
Transmissible LCD is located between the above two, the bottom polarizer can partially reflect the light, generally backlit. You can turn off the backlight when the light is good; When the light is not good, you can turn on the backlight and use the LCD.
2. Transmission type) The bottom polarizer of the LCD is a transmission polarizer, which requires continuous use of backlight, generally used in a poor light environment.
The LCD black and white screen is divided into positive and negative films according to the display mode.
1. Positive)LCD displays black characters on a white background, and displays well in reflective and transmissible LCDS;
2. Negative)LCD presents white characters on a black background, generally used for fully transparent LCD liquid crystal. Backlight, legible font.
Three connection methods of black and white LCD screen
1. The connection between the black and white liquid crystal display and the conductive rubber strip: When using this connection method, the conductive rubber strip is required to fix the liquid crystal display and the PCB together with structural parts. Because the electrode spacing can be made very small, it is suitable for products with many drive paths.
2. Black and white LCD metal pin connection: The metal pin is fixed on the external lead of the LCD screen, which can directly fix the LCD screen on the printed circuit board, or the LCD screen can be inserted into the socket of the printed circuit board. Metal pin spacing is 2.54 mm, 2.0 mm and 1.8 mm. Applicable glass thicknesses are 1.1 mm, 0.7 mm and 0.55 mm.
3. Black and white LCD screen hot pressing soft tape connection: Connect LCD and PCB with soft tape. Because the substrate is soft, it is easy to fix when used, and the installation thickness can be reduced.
