Abstract

The invention provides a liquid crystal display, which has no shadow mask restriction, and has smaller and finer pixels; therefore, the liquid crystal display can accommodate more pixels and more information in the display window area of ​​the same size, and organic polymer synthesis The material has extremely high purity and is made under extremely clean conditions. The driving voltage requirement is low, the driving current is very small, the deterioration is reduced, the service life is long, the utilization rate of the display content is the highest, and the structure can be made very small. The structure is also convenient for large-scale and automatic production. At present, the production of display devices is mostly produced by automatic and semi-automatic integrated processes. Only a small number of workers can start a production line with an annual production of thousands of pieces.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to a backlight source module and a liquid crystal display thereof. Background technique [0002] The display is the most important terminal output device of the electronic computer, and it is the window for man-machine dialogue. The display is composed of a circuit part and a display device. What kind of display device is used determines the circuit structure of the display and also determines the performance index of the display. Indicating or displaying devices are mainly divided into mechanical indicating devices and electronic display devices. The traditional voltage or ammeter head is a typical indicating device, which is widely used in regulated power supplies, multimeters and other instruments. With the improvement of the self-energy level of electronic instruments, the use of electronic display devices is becoming more and more extensive, mainly including light-emitting di...
