Hi
I'm kinda newbish to this, but was super psyched when I was able to install Android on my tablet.
these are the specs of the screen:
Screen Diagonal [mm] 15.6”
Active Area [mm] 344.232 (H) x 193.536 (V)
Pixels H x V 1366(x3) x 768
Pixel Pitch [um] 252 (per one triad) × 252
Pixel Arrangement R.G.B. Vertical Stripe
Display Mode TN Mode, Normally White
White Luminance ( Center ) [cd/m2] 400 cd/m2 (Typ.)
Contrast Ratio 500 (Typ.)
Optical Response Time [msec] 8ms (Typ., on/off)
Nominal Input Voltage VDD [Volt] +5.0 V
LCD Power Consumption [Watt] 2.15 W (Typ.), 2.5 W (Max.)
(all black pattern)
LED Power Consumption [Watt] 7.8 W (Typ.), 8.5 W (Max.)
(all black pattern)
Weight [g] 1250 (Typ.), 1350(Max.)
Physical Size [mm] 363.8(W) X 215.9(H) X 16.85 (D) Typ.
Electrical Interface One channel LVDS
Support Color 16.7M colors (RGB 6-bit + Hi-FRC )
The Problem I'm facing is that on Android 4.4 the screen resolution fit perfectly, while on Android 8 it looks like this:
There is also a white glance to it.
when running on 4.4 (booted from the SDcard) it looks normal with vibrant colors, so a hardware issue is not causing this white layer
this is my override
setenv extra_bootargs video=mxcfb0:dev=ldb,bpp=16,if=RGB666 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off
or
setenv video video=mxcfb0:dev=ldb,bpp=16,if=RGB666 video=mxcfb1:off video=mxcfb2:off video=mxcfb3:off
thanks
