13description: |
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.
