description: |
ST7701 designed for small and medium sizes of TFT LCD display, is
capable of supporting up to 480RGBX864 in resolution. It provides
several system interfaces like MIPI/RGB/SPI.
Techstar TS8550B is 480x854, 2-lane MIPI DSI LCD panel which has
inbuilt ST7701 chip.
Densitron DMT028VGHMCMI-1A is 480x640, 2-lane MIPI DSI LCD panel
which has built-in ST7701 chip.
