Title:
DATA PROTECTION SYSTEM AND METHOD FOR DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/093451
Kind Code:
A1
Abstract:
A data protection system and method for a display device. The system comprises a memory unit (210), a timing control unit (220), and a switch module (300). The switch module (300), according to a potential change of a control signal (S1), selectively outputs a constant potential signal (S3) or a read/write control signal (S2) to the memory unit (210). The switch module (300), upon outputting the constant potential signal (S3) to the memory unit (210), disconnects an electrical coupling between the read/write control signal (S2) and a protection control terminal (211). The memory unit (210), according to the obtained signal, maintains a write protection status of timing control data (212), or causes the data to be switched between a readable/writable status and the write protection status.
