TDA2PXEVM: LCD display Integration

Dipti,

Difficult to say what is the problem, as I don’t know what is expected output.  Can you first save input image to the DSS and compare it against DSS output?

It seems LCD is able to recognize input image, so timing is correct, but seems issue with the colors.

Are you seeing some color swap issues? If required, we can swap R and B colors in DSS.

Rgds,

Hello Brijesh,

We tried displaying the same image on HDMI display, it works well.

This is the output of yuv image coming from ISP:

/resized-image/__size/320x240/__key/communityserver-discussions-components-files/791/pastedimage1622038200689v2.png

This is the corresponding image seen on HDMI display:

/resized-image/__size/320x240/__key/communityserver-discussions-components-files/791/pastedimage1622037741545v1.png

Can you give more information about swapping R and B colors in DSS that you mentioned earlier.

Thanks,

Dipti

Dipti,

It is difficult to correlate, can you share all three images, is isp output, hdmi output, and lcd output? 

R and B can be swapped using CSC module, but before that we need to first understand if the issue is really R and B getting swapped.

Hello Brijesh,

Thank you for your suggestions. It seems there was issue with hardware on client side . So the issue is resolved.

But thank you for prompt replies.

Thanks,

Dipti
