Lines appearing on display at startup

Hi!

We use the 7" capacitive touchscreen (LT161010) and during startup random stripes appear on the screen:

Other than that the screen works fine, after the kernel starts the configured splash screen is displayed.

Is there a way to disable the screen until the initialization happens?

Thanks!

Hello,

yes you need to switch of the Backlight control in Uboot. So you need to build your own Uboot.
