|
The nt35950 IC from Novatek is a Driver IC used to drive MIPI-DSI panels,
|
||
|
|
with Static RAM for content retention in command mode and also supports
|
||
|
|
video mode with VESA Frame Buffer Compression or Display Stream Compression
|
||
|
|
on single, or dual dsi port(s).
|
||
|
|
This DDIC is also capable of upscaling an input image to the panel's native
|
||
|
|
resolution, for example it can upscale a 1920x1080 input to 3840x2160 with
|
||
|
|
either bilinear interpolation or pixel duplication.
