And another blender test for TFT display material.
While faking CRT screens seems to be quite common thing to do I haven’t seen that many attempts at emulating TFT displays and their characteristic defects like limited viewing angles, poor contrast, ghosting / smearing issues and backlight bleed.
4:3 320x240 TFT display with some backlight bleeding, click larger to see the screen at full size

My material setup includes screen resolution setup, glossy display coating, adjustable procedural rgb mask / diode gaps, backlight bleed mask with tint control and black level adjust.
The X and Y resolutions define how input image is pixelized and the aspect ratio can differ from the resolution and non-square pixels are also supported. The UV map of screen area should cover the whole image size so every pixel will be drawn.

TODO: TN panel like viewing angles, custom bitmap rgb masks, motion blur / ghosting
PS. used older blender work of mine for the display image
