| 15 | description: | |
| 16 | MIC (Mobile Image Compressor) resides between DECON and MIPI DSI. MIPI DSI is |
| 17 | not capable of transferring high resoltuion frame data as DECON can send. MIC |
| 18 | solves this problem by compressing the frame data by 1/2 before it is |
| 19 | transferred through MIPI DSI. The compressed frame data must be uncompressed |
| 20 | in the panel PCB. |
