Display driving method and display apparatus

A display apparatus configured to display a display image, and comprising a plurality of scan lines;

• a plurality of data lines driven by a data driving circuit;
• a storage medium storing several lookup tables;
• and a processor comprising:
• a data line detection module, configured to calculate an average brightness of each of the plurality of data lines of the display image, calculate an average brightness difference of each of the plurality of data lines, determine whether the average brightness difference of a current data line of the plurality of the data lines is greater than a predefined threshold value;
• wherein when the average brightness difference of the current data line is greater than a predefined threshold value, the data line detection module sets the current data line as a target data line and sets several data lines of the plurality of data lines adjacent to the target data line as auxiliary data lines;
• the data line detection module further serves the target data line and the auxiliary data lines as compensation data lines;
• a compensation parameter calculating module, electrically connected to the data line detection module, the compensation parameter calculating module configured to calculate compensation parameters corresponding to each of the compensation data lines respectively;
• a trim parameter calculating module, electrically connected to the data line detection module, the trim parameter calculating module configured to calculate trim parameters corresponding to each of the compensation data lines respectively;
• and
• a brightness calculating module, electrically connected to the compensation parameter calculating module and the trim parameter calculating module;
• the brightness calculating module configured to calculate an output brightness value of each of the compensation data lines based on an original brightness value, the calculated compensation parameters, and the calculated trim parameters of each of the compensation data lines, and output the calculated output brightness to the data driving circuit;
• wherein the compensation parameters comprises an original compensation value and a ratio value;
• the display image comprises at least one foreground image and at least one background image;
• the compensation parameter calculating module further confirms an average brightness difference interval, where the average brightness difference is located in, by a table lookup operation based on the average brightness difference of the target data line and the specified condition corresponding to the target data line, and calculating an original compensation value of the target data line by a linearly interpolating operation based on two binding-point average brightness difference values of the confirmed average brightness difference interval;
• the compensation parameter calculating module further obtains the ratio value of each of the auxiliary data lines by a table lookup operation based on a position of each of the auxiliary data lines related to the target data line.
