| 13 | description: | |
| 14 | TI DLPC3433 is a MIPI DSI based display controller bridge |
| 15 | for processing high resolution DMD based projectors. |
| 16 | |
| 17 | It has a flexible configuration of MIPI DSI and DPI signal |
| 18 | input that produces a DMD output in RGB565, RGB666, RGB888 |
| 19 | formats. |
| 20 | |
| 21 | It supports upto 720p resolution with 60 and 120 Hz refresh |
| 22 | rates. |
