#159787 - How do you drive a RGB color LCD display? |
I've been playing with a 320x240 color LCD display with a microprocessor interface with on-board display RAM and it was relatively easy to get it up and running driving it with a P89V51RD2 as a dedicated graphics "server". This particular display was not "sunlight viewable" so I'm switching to a Sharp model LQ035Q7DH06 sunlight viewable 320x240 RGB LCD display.
The problem is that this display has no onboard RAM and requires vertical and horizontal synch pulses, a "dotclock" and 6 bit wide RGB data for each of the three colors very fast (6Mhz or so). I have trawled the internet and asked various graphics color LCD vendors for schematics or the names of chip(s) to use to create these signals but it seems to be a closely guarded secret. I have no idea how to create these signals or what chip(s) to use and wonder if anyone can steer me into the right direction. Regards, Bert |

| buy an evaluation board | 01/01/70 00:00 | |
