The connection method of lcd display screen:
1, conductive tape connection
When using this connection method, a structural part is needed to fix the LCD, the conductive adhesive strip and the PCB board together.
Because the electrode spacing can be made small, it is suitable for products with a large number of driving circuits.
2, metal pin connection
Fix the metal pins on the outer leads of the LCD. You can either directly fix the LCD on the PCB or plug the LCD into the socket of the PCB.
The metal pin pitch is 2.54mm, 2.0mm, 1.8mm
Applicable glass thickness is 1.1mm, 0.7mm, 0.55mm
3, hot-pressed soft belt connection
Use a soft tape to connect the LCD and PCB board together.
Because the base is soft, it is convenient to fix in use, and the installation thickness can be reduced.
The above content is an introduction to the connection method of the LCD display. LCD products are non-active light-emitting electronic devices. Under the action of an electric field, the arrangement direction of liquid crystal molecules is changed. It does not have light-emitting characteristics and must rely on backlighting. The emission of the light source in the module can obtain the display performance, and then use the different excitations of the three primary colors of R, G, and B to complete the electrical-optical conversion through the red, green, and blue primary color filter film, and complete the time domain and space domain. Color reappears. The brightness of the LCD is determined by its backlight module. It can be seen that the performance of the backlight module directly affects the display quality of the liquid crystal panel.
