3.Performance Parameters
1) Input signal amplitude range:
Video signal amplitude 0.7~1.4Vp-p range,the module can display images correctly
To 8 gray-scale signal and the color bar signal,for example
The signal amplitude range of 0.7~1.4Vp-p ,gray can be displayed 8-order gray,no color cast color bar
Test signal amplitude for different image brightness of the display module
2) Video Signal System
Module can automatically identify:PAL B, D, G, H, I and NTSC M,NTSC M4.43 signal .
