Displaying unwanted lines on LVDS type LCD in i.MX6S environment

Question asked by Surya G on Apr 21, 2014



We are working on i.MX6S platform on ET-Kernel environment.

We are interfacing the LVDS (SPWG) type LCD to LDB module

We are facing an issue while displaying gradation red colour images on LCD at particular pixel values. Please find the attached image.

When data changes from 0xCF to 0xD0( red component in pixel), we observe a dark line(black). This happens only in red colour. Blue and Green colour are working fine.

Could anyone suggest me to solve the above issue.
