Channel parameters signal and the effective enable signal of channel are taken, the wherein effective enable signal of channel is sent to mipi point screens adjustment module 4,
It reads channel parameters signal and is sent to parameter processing module 2, after parameter processing module 2 receives the signal, identical parameters processing
Unit 201 exports the identical data of single channel to Multichannel controller module 3, and multichannel parameter processing unit 202 presses corresponding channel
Different data is exported to Multichannel controller module 3；
Step 3：Instruction that Multichannel controller module 3 receives the image data of the input of parameter processing module 2, module is spread its tail,
After mipi module adjustment parameters, corresponding channel data are read, and image data is converted to rgb image data by channel number, so
Spread its tail instruction, mipi modules adjustment parameter of rgb image data and module is issued to mipi point screens adjustment module 4 parallel afterwards, wherein
Identical data is sent respectively to each mipi point screens adjustment module 4, and different data is handed down to corresponding according to channel number correspondence
Mipi point screens adjustment module 4；
Step 4：Mipi point screens adjustment module 4 receives rgb image data, the module that Multichannel controller module 3 inputs and spreads its tail
The reference points screen such as instruction, mipi modules adjustment parameter and system point screen enabling signal, systematic reset signal, system cut-in voltage
Control signal after, in mipi spread its tail instruction sending module 401 enter low power consumption transmission pattern, according to mipi consensus standards send out
Send instruction of spreading its tail that the instruction that will spread its tail after being sent is instructed to be sent signal and is sent to image data turn to mipi modules 5
Mipi signal transmitting modules 402, image data turn mipi signal transmitting modules 402 and receive after instruction of spreading its tail is sent signal
Into high speed transmission mode, the rgb image data of reception is converted to mipi formatted datas and is sent to mipi modules 5, and parameter
Module for reading and writing 403 enters low power consumption transmission pattern, and the adjustment parameters such as vcom, gamma are exported to mipi according to mipi protocol formats
