Abstract
A method of compensating luminance of an organic light-emitting diode (OLED) operated with a transistor in a pixel cell of a display panel includes measuring a first parameter of the transistor and a parameter of the OLED, and generating a lookup table accordingly; converting original display data to target display data according to the lookup table; outputting the target display data to the pixel cell; and compensating a second parameter of the transistor when the target display data is received by the pixel cell.
Claims12
A method of compensating luminance of an organic light-emitting diode (OLED) operated with a transistor in a pixel cell of a display panel, comprising:
- measuring a first parameter of the transistor and a parameter of the OLED, and generating a lookup table accordingly;
- converting original display data to target display data according to the lookup table;
- outputting the target display data to the pixel cell;
- and
- compensating a second parameter of the transistor when the target display data is received by the pixel cell.
A display system, comprising:
- a display panel, comprising a plurality of pixel cells, each of which comprising an organic light-emitting diode (OLED) operated with a transistor;
- an external compensation module, for measuring a first parameter of the transistor and a parameter of the OLED, and generating a lookup table accordingly;
- and
- a controller, for converting original display data to target display data according to the lookup table, and outputting the target display data to one of the plurality of pixel cells;
- wherein a second parameter of the transistor is compensated when the target display data is received by the pixel cell.
