Display Apparatus and Display Control Method with Redundancy Repair Function

A display apparatus, comprising:

• a display module including a plurality of display pixel units physically arranged in M columns and P rows, wherein each of the plurality of display pixel units includes a pixel unit memory and a pixel unit logic circuit, the pixel unit memory configured to store a portion of display data corresponding to the display pixel unit, and the pixel unit logic circuit being coupled to the pixel unit memory,
• wherein the pixel unit memory comprises:
• a primary pixel memory including T primary memory bits, where T is an integer greater than or equal to 1;
• and
• a redundant pixel memory including R redundant memory bits, where R is an integer greater than or equal to 1;
• a nonvolatile memory;
• and
• a drive control circuit configured to control the display module to execute a pixel memory redundancy repair procedure for obtaining and storing repair data in the nonvolatile memory, and configured to, during a display procedure, read the repair data from the nonvolatile memory and control the plurality of display pixel units to perform image display based on the repair data and the display data;
• wherein during the display procedure, when at least one of the T primary memory bits is determined to be faulty, the pixel unit logic circuit controls the non-faulty portion of the T primary memory bits and the R redundant memory bits to cooperate based on the repair data for storing or retrieving the display data.
