Abstract:
1. A flat panel display device, comprising: a display panel; a memory that stores location information about a panel defect location of the display panel and a compensation value that is dispersed to a plurality of pixels; and a compensating part that detects the data that are displayed at the panel defect location and adjusts the data that are displayed at the panel defect location with the compensation value from the memory; wherein compensating part includes: 1) a location judging part that finds a location of the data by use of any one or more of the vertical/horizontal synchronization signal, a dot clock and a data enable signal; 2) a gray level analyzing part that analyzes the gray level area of the data; 3) an address generating part generating a read address that accesses the memory by use of the gray level information and the location of the data supplied from the location judging part and the gray level analyzing part; 4) a dithering part disperses the compensation value loaded from the memory to a plurality of pixels by the dithering method; wherein the dithering part includes: 1) a pixel location judging part that judges a pixel location by use of any one or more of the vertical/horizontal synchronization signal, a dot clock and a data enable signal; 2) a gray-level level judging part that judges the level of the gray level of the compensation value and generates a dithering data by use of the pixel location information from the pixel location judging part; 3) an operator that generates a corrected data by increasing or decreasing the data with a dithering data.
