AI Technical Summary

Problems solved by technology

However, during the manufacturing process of the display device, the pixels may be abnormal due to manufacturing process factors, and cannot emit light normally, thus producing dark or dead pixels on the display device.
The dark spots or dead spots will make the display brightness of the display device uneven, thus failing to provide a good user experience

Abstract

The present invention provides a method of compensating brightness of abnormal pixels of a display device. The display device includes a plurality of normal pixels. The method includes: enhancing the brightness of at least one of the normal pixels to compensate the brightness of the abnormal pixel. The at least one normal pixel has the same color as the abnormal pixel and is adjacent to the abnormal pixel.

Description

technical field [0001] The invention relates to a compensation method, in particular to a method for compensating the brightness of abnormal pixels of a display device. Background technique [0002] The display device includes a plurality of pixels for displaying image frames. However, during the manufacturing process of the display device, the pixels may be abnormal due to manufacturing process factors and cannot emit light normally, thus producing dark or dead pixels on the display device. The dark dots or bad dots will cause the display brightness of the display device to be uneven, thus failing to provide a good user experience. Therefore, using an appropriate compensation method to compensate the brightness of the abnormal pixels of the display device to make the display brightness of the display device uniform is one of the important issues at present. Contents of the invention [0003] By using the compensation method of the present invention to compensate the bri...
