| 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. |
