| 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. |
