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.
