lcd displays monochrom free sample

Modular 9.3" 4K Monochrome LCD for XiP, featuring a 52 micron pixel pitch. This module plugs directly into the XiP without the need to manually attach bus wires or seat the screen. Each LCD is rated at over 3,000 hours requiring 1-2 replacements per year based on printer usage.

[Wenting Zhang] is clearly a fan of old school STN LCD displays, and was wondering how various older portable devices managed to drive monochrome LCDs panels with multiple grey levels. If the display controller supports multiple bits per pixel, it can use various techniques, such as PWM, in order to produce a pseudo-grayscale image. But, what if you have a monochrome-only display controller? With a sufficiently high pixel clock, can you use software on the application side of things to flip those pixels in such a manner as to give a reasonable looking grayscale image?

The thing is, our brains do weird things with the visual signals we perceive. Regions with the same gray value, will be pulsating at the same time, and the eye will be drawn to it and perceive flickering. So, the next trick was to try to decouple nearby pixels in such regions using a LFSR sequence, which did give an noticeable improvement. The real aim was to try to play video through the LCD, so after investigating spatial dithering, [Wenting] moved over to wondering if he could also dither in time, i.e. can the error in the time sequence be smoothed out in a similar manner, to make the video look better? By using a simple noise-shaper, the video looked noticeably smoother, and practically flicker free. Great results! All in all, this is a long video to watch, but so crammed with useful tricks that it is in our opinion definitely worthy of your time.

We’re no strangers to driving retro displays with modern hardware, for example CRTs, and whilst we’re thinking about retro displays, how about this retro (and quite disturbing) touch-enabled CRT from the early ’80s?
