Abstract
This invention relates to a flat panel display device that is adaptive for perfectly compensating a panel defect by performing an electrical compensation on pixels in a panel defect location, and a method of controlling a picture quality thereof. A flat panel display device according to an embodiment of the present invention includes a display panel which has a non-defect area and a panel defect area; a memory which stores a first compensation, a second compensation data, a third compensation data, a fourth compensation data, and a fifth compensation data; a compensation part; and a driver for driving the display panel in use of the data modulated by the compensation part.
Claims42
A flat panel display device, comprising:
- a display panel which has a non-defect area and a panel defect area and has at least one link pixel where adjacent pixels are interlinked;
- a memory which stores a first compensation data for compensating data to be displayed on odd-numbered lines in the panel defect area, a second compensation data for compensating data to be displayed on even-numbered lines in the panel defect area, a third compensation data for compensating data to be displayed on odd-numbered lines included in a boundary part between the panel defect area and the non-defect area, a fourth compensation data for compensating data to be displayed on even-numbered lines of the boundary part, and a fifth compensation data for compensating data that are to be displayed in the link pixel;
- a compensation part that modulates the data to be displayed in the panel defect area, a fixed area inclusive of the boundary part and the link pixel, with the compensation data;
- and
- a driver for driving the display panel in use of the data modulated by the compensation part.
A picture quality controlling method of a flat panel display device, comprising:
- a step of determining a first compensation data for compensating data to be displayed on odd-numbered lines in the panel defect area, a second compensation data for compensating data to be displayed on even-numbered lines in the panel defect area, a third compensation data for compensating data that are to be displayed on odd-numbered lines included in a boundary part between the panel defect area and a non-defect area of a display panel, a fourth compensation data for compensating data to be displayed on even-numbered lines included in the boundary part, and a fifth compensation data for compensating data that are to be displayed in a link pixel where adjacent pixels are interlinked in the display panel, by an inspection process and a repair process of the display panel;
- a step of storing the compensation data at a memory;
- a compensation step of modulating the data to be displayed in the panel defect area, a fixed area inclusive of the boundary and the link pixel, with the compensation data stored on the memory;
- and
- a step of driving the display panel in use of the data modulated by the compensation step.
