|
TI DLPC3433 is a MIPI DSI based display controller bridge
|
||
|
|
for processing high resolution DMD based projectors.
|
||
|
|
|
||
|
|
It has a flexible configuration of MIPI DSI and DPI signal
|
||
|
|
input that produces a DMD output in RGB565, RGB666, RGB888
|
||
|
|
formats.
|
||
|
|
|
||
|
|
It supports upto 720p resolution with 60 and 120 Hz refresh
|
||
|
|
rates.
