Development of LCD test board scheme
LCD test board PCB circuit board main characteristics of circuit board scheme design, development and production
1. Power input: 12V input is recommended, ranging from + 7V to 15V;
2. Working temperature: - 20 ℃ - + 65 ℃
3. The default program is 2av + VGA, and YPbPr is controlled by the switch in the menu;
4. Built in 8 test images: red, green, blue, black, white, gray, color bar and black-and-white box, which can be adjusted manually and cycled automatically;
5. Support OSD key board. OSD language includes Chinese and English. Customers can adjust brightness, contrast, chroma and other functions through the key board;
6. Support infrared remote control input: customers can realize any function through IR;
7. Support external audio board and audio menu adjustment;
8. Support the panel that needs SPI data initialization;
9. No signal shutdown setting, the default is not to use this function, and can also be set by yourself;
10. The drive board can support most LCD screens, and some LCD screens need to be equipped with adapter boards;
11. Because there are too many LCD models, please contact our technicians when necessary and confirm whether you support the LCD you use.
The above configuration information is for reference. Our company can make matching parameters according to different LCD test boards, control boards, different use environments and different functional requirements, and can issue hardware configuration documents.
As long as you put forward the functional requirements of the product, or even just an idea, we can design the control circuit of the product according to your requirements to realize the functions you want.
