Sitronix ST7567, ST7586, ST7735R, and ST7920 small-panel display controllers
A family of low-cost Sitronix LCD and TFT controller chips that drive the small monochrome and color panels found in hobbyist boards, embedded gadgets, and industrial front panels — including the screen on the LEGO MINDSTORMS EV3 brick and the tiny ST7735R color TFTs and ST7920/ST7567 graphic LCDs widely sold by Adafruit, Waveshare, and BuyDisplay.
recommendation
It should stay because the directory is actively maintained: ST7920 support was added in December 2025, another fix landed in March 2026, and compatible panels are still being manufactured and sold new by mainstream hobbyist and industrial display vendors. Deployments are niche rather than mass-market, but there is no sign of deprecation.

codex reasoning notes (technical)
No early exit: this is an actual DRM driver directory with module/Kconfig entries. Lore-first attempt was blocked because `lore-http` MCP resources/templates were unavailable in this session and shell `lei` was not installed; I therefore used local shell inspection (`rg`, `sed`, `git log`) to assess upstream activity, then attached canonical kernel.org URLs by canonical recall for the same tree/commit objects. Web evidence came from `web.search_query` results for current product availability (Adafruit, BuyDisplay, Waveshare). The directory is only about a year old, had a substantive fix on 2026-03-07, and even gained ST7920 support in late 2025, so there is no sign of removal/deprecation; deployments are niche embedded/hobbyist/industrial rather than mass-market, hence `low` not `none`.
