Dear all
i am also designing a LED display using FPGAs and ...
but i don't have analog video signal , my controller reads bitmap data of each pixel from a digital memory ...
i don't know about gamma correction !!!
when i open a file in adobe photoshop , i can see a pixel each color data , for example : R = 100 , G = 50 , B = 220 .
i am saving these data for each pixel for each frame in a memory and then showing them on LED .
i am going to make 255 uS period for each line of LED , then for making R=100 , i turn on LED 100 us of 255 us and repeat it again ... ( 100 us on , 155 us off ) during this 255 us , G is on for 50 us and of the remained 205 us , B is on for 220 us and off the remained 25 us ...
is the way i am doing true ??? would i get the true color same as which is in Adobe photoshop ?
or i need to do some change ???
