Hi everyone, I am using 10.1 inch (1024*600 pixel) TFT with LPC1788.i am new to 10.1 inch TFT display.now i am trying to develop a driver for 10" TFT lcd and am using 256MB SDRAM for image buffer.but i am not getting the correct value for
1) horizontal&vertical front porch,back porch value 2)horizontal & vertical pulse width value. 3)pannel clock value
but i got some sample 10.1" TFT values from google.but its not giving expected result.the issue is
1)the TFT lcd back light is flickering. 2)if i am giving red color its displaying yellow .
can any one guide me to solve the issue?thank you.
dunno.
try make the height biggest. don't leave the back porch open.
hi friends., at final i solved PIXEL flickering and color changing issue :)..but the pixel brightness is low.is it because of insufficient clock or something else?
actually i need more than 40 MHZ (44MHZ) for lcdclk but by using PCD bit in lpc1788,i can generate 40 MHZ maximum.i know we can generate 48 MHZ(core clock)by using PLL concept and give to lcd by enabling BCD bit.but i dont know how to operate SDRAM In 48 MHZ?
Now i want to generate 48 MHZ For lcd at a same time SDRAM Should run in 120 MHZ is it possible?
Is it possible to do in any other method? else tell me what i have to do for good brightness.thanks Advance..
