Claim 2:
3. The display apparatus according to claim 1, wherein the memory is a non-volatile memory; and
the driver includes:
a random memory coupled to the non-volatile memory and configured to obtain and temporarily store the at least one set of correspondences from the non-volatile memory, the random memory being further coupled to the signal transmission interface, and further configured to obtain the image data from the signal transmission interface;
a plurality of registers coupled to the random memory;
a controller coupled to the random memory and the plurality of registers,
the controller being configured to: control a register to obtain, according to each grayscale data in the image data, a register value corresponding to the grayscale data from a set of correspondences in the random memory, and control the register to store the register value; and
a grayscale voltage output circuit coupled to the plurality of registers and the display panel, the grayscale voltage output circuit being configured to output, according to the register value stored in the register, a grayscale voltage corresponding to a grayscale voltage value represented by the register value to the display panel.
