I am using Apalis T30 SOMM module with Ixora V1.0A Carrier Board. I have interfaced 7" TFT LCD display using LVDS. The details of the LCD display is as below:
Resolution : 1024 x 600
Display Colors : 262K colors (RGB 6-bits)
I made the settings in the U-Boot command prompt as below:
setenv vidargs 'video=tegrafb0:1024x600-18@60 fbcon=map:1' setenv lvds_setting 'gpio set 216;gpio set 222;gpio set 226;gpio set 225;gpio set 221;gpio set 220' bootcmd=run lvds_setting;run emmcboot
Once the Linux kernel is booted, I executed the below commands,
/usr/bin/lvds-single-channel.sh echo 0 > /sys/class/backlight/pwm-backlight/bl_power echo 200 > /sys/class/backlight/pwm-backlight/brightness
With these settings, the display is up and I am able to see the LXDE Desktop environment. But, the contrast is not so good. I changed the brightness level but no improvement.
So, can I please get some help about how to change the contrast ratio.
I am attaching the snap shots of the display.
Thanks & Regards
