Data access method for a timing controller of a flat panel display and related device

A flat panel display for saving memory cells for displaying images comprising:

• a panel;
• a data-line-signal output circuit coupled to the panel, for outputting pixel data of the images;
• a scan-line-signal output circuit coupled to the panel, for driving the panel to display the images;
• and
• a timing controller coupled to the data-line-signal output circuit and the scan-line-signal output circuit, the timing controller comprising:
• a line buffer including a plurality of memory cells, wherein the plurality of memory cells is divided into a first section and a second section, and the number of memory cells in the first section is greater than the number of memory cells in the second section;
• a control unit coupled to the line buffer, for writing a first number of pixel data into the first section and performing at least two times of different writing and reading processes on each of at least one memory cell of the second section to write different pixel data in the different writing and reading processes, respectively, thereby writing a second number of pixel data into the second section, wherein the first number of pixel data and the second number of pixel data are included in a plurality of pixel data corresponding to a row of a frame and the first number is equal to the second number;
• and
• a data packing unit coupled to the control unit, for reading the plurality of pixel data from the plurality of memory cells according to an order and outputting the plurality of pixel data to the data-line-signal output circuit.
