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.
