description: |
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.
