Abstract:
A display device is disclosed. The display device includes: a plurality of pixels; a memory storing a lookup table including compensation values for pixels at specific locations of the display. The lookup table also stores compensation values obtained by a bilinear compensation method. The display also includes a data compensator calculating the compensation values corresponding to a location where an image signal is displayed using the compensation values and substitution values stored in the lookup table. The substitution values are obtained by bit-shifting the compensation values acquired by bilinear compensation method. The display device avoids the need to use large and slow divider circuits used in ICs implementing bilinear compensation method.
Abstract:
A method of displaying an image on a display panel having a plurality of pixels arranged as rows and columns includes calculating a row correction value corresponding to a pixel position of a received data based on an average luminance of pixels in a pixel row of a sample-grayscale image, calculating a column correction value corresponding to the pixel position of the received data based on an average luminance of pixels in a pixel column of the sample-grayscale image, generating correction data for the received data using a row correction value and a column correction value corresponding to a pixel position of the received data, and converting the correction data to a data voltage to provide a data line of the display panel with the data voltage.
Abstract:
A display panel apparatus includes a display panel and a timing controller, and a data driver. The display panel includes a first subpixel and a second subpixel. The timing controller is configured to receive a first subpixel data for the first subpixel and a second subpixel data for the second subpixel. When the second subpixel is determined to be defective, the timing controller generates a compensated grayscale of the second subpixel data. The data driver is configured to apply a precharge voltage to the second subpixel and a charging voltage to second subpixel through a data line, wherein the precharge voltage is based on a grayscale of the first subpixel data and the charging voltage is based on the compensated grayscale of the second subpixel data.
