Hi,
I am designing a interface board for colour graphics LCD. The idea is that, as of now, the LCD is 3.5", 320 X 240 resolution but could be interfaced to other LCDs as well (of course TFT, up to some resolution etc).
Unfortunately there is no standard interface for graphic LCDs. Some are of 50 lines (with and without Tcons, invertors etc), SPI, I²C and so on.
All I could think is I can have a board which has,
1. Power supply which generates ±8.5V and +16V from 3.3V.
2. Colour bits (R, G and B); may be 8 lines each.
3. Hsync, Vsync and dot clock and,
4. Two PWM channels to control the brighness.
*At least gate drivers would be there on LCD.
Some LCD may have power supply and/or timing controller and /or RAM etc. So above blocks on the interface card could be bypassed accordingly.
Kindly advice if you have any suggestions if I can go ahead with this idea.
