Note: The data of D1 is send by MCU, and D2, D3, D4 through pixel internal reshaping amplification to

transmit.

Note: Data transmit in order of GRB, high bit data at first.

Typical Application Circuit

Remarks:

Rx is the IC’s protective resistance, power spike and reverse connection of the battery power terminal will be

protected, its value is less than 100ohm. C1 is the bypass capacitor for VDD, its value of 100NF.
