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.
Please read the manual for YOUR panel, not random parameters found on Google for other panels of similar size and dimensions.
have you tried changing the front porch to 68?
hi harish kapoor, front porch value 68 for horizontal or vertical.? what about remaining value? no need remaining value for 10" TFT lcd?
dunno.
try make the height biggest. don't leave the back porch open.
Again, have you studied the documentation for your particular panel?
Have you contacted the manufacturer or supplier of your particular panel for support?
hi friend. thank you for your response.i studied the documentation.sorry The model no is WY101ML285HS18A .its a 10.1" TFT display.1024*600 pixel resolution.i searched a lot if u find any information tell me.
Did you buy an LCD module without first checking the data sheet. At the very least, you should have determined the availability of data sheets.
And by no means of the imagination could it be regarded as a Keil related question.
hi, i didn't bought the LCD.already its purchased and now i am trying to use this.i got data sheet for the particular LCD also.but its not heaving any timing characteristics.with out timing characteristics i cant give value for horizontal /vertical front porch and back porch .that's why i am asking is there any one interfaced 10.1" TFT LCD with LPC1788 or any micro controller?if u did already give me some idea.i know different LCD manufacture value wont work.just try only.
You find it strange if I recommend that people first look at datasheets before deciding what to buy?
Post a link to the manual you are working with. Googling the part# isn't helping.
Post a link to where you bought it.
Dear Friend., the link for the TFT lcd manual is: www.lpcware.com/.../10.1】RG101ML308HS18A(HSD10.1)-without any logo_1.pdf

hello friends how to use TFT lcd in DE mode by using the following value? Vertical Display Time Vertical Blanking Time Horizontal Display Time Horizontal Blanking Time can any one can hep me?
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..
