MIC (Mobile Image Compressor) resides between DECON and MIPI DSI. MIPI DSI is
|
||
|
|
not capable of transferring high resoltuion frame data as DECON can send. MIC
|
||
|
|
solves this problem by compressing the frame data by 1/2 before it is
|
||
|
|
transferred through MIPI DSI. The compressed frame data must be uncompressed
|
||
|
|
in the panel PCB.
