Dear all,

How do I drive an LCD panel (160x160) with only driver IC on it
from 8051 without the help of a LCD controller IC?

Hi michael03,

You have to clock in every pixel and to generate HSYNC and VSYNC.
The exact howto depends on the type (STN, TFT, s/w or color) of your
LCD. Theoretically it can be done with an 8051, but the problem is
the performance. You have to update your 25'600 Pixels every 20-30ms.
This gives a throughput of over 1'000'000 Pixel/s. I think this would be
critical with your 8051.
Another possibility is to share RAM with a CPLD that does this stuff.

Bye

Try another cpu like dragonBall or ARM

Why not try another cpu like dragonBall or ARM(like sumsung 440B0x), they are cheap enough , only 3-5 dollars a chip, and have LCD controller in chip.
