Abstract
The preset disclosure provides a data burning method and a data burning device. The data burning method comprises receiving a differential signal data packet, which is transmitted by a signal generator, by a driver IC through a differential signal interface, the differential signal data packet including grayscale data; parsing the differential signal data packet by the driver IC to obtain the grayscale data; and burning the grayscale data to a memory by the driver IC.
Claims7
A data burning method, performed by a display module including a driver Integrated Circuit (IC) and a memory that are internal components of the display module, the driver IC being connected with the memory through serial peripheral interface (SPI) transmission lines, the method comprising:
- receiving, by the driver IC, a differential signal data packet from a signal generator, through a differential signal interface, the differential signal data packet comprising grayscale data, wherein the differential signal interface is a mobile industry processor interface (MIPI), and the differential signal data packet is an MIPI data packet;
- parsing, by the driver IC, the differential signal data packet to obtain the grayscale data and storing the grayscale data in a register of the driver IC;
- packaging, by the driver IC, the grayscale data of the register of the driver IC into an SPI data packet;
- and
- burning the grayscale data in the SPI data packet to the memory through the SPI transmission lines,
- wherein the grayscale data comprises grayscale vertical stripe (Demura) data provided for testing of the display module, and the memory comprises a Flash memory.
