Display driver


An lc display driver ic suitable to drive source voltage signals to a liquid crystal display, and including an lcd source driver that can convert video image data into a selected one of n gamma-compensated analog gray-level source voltages corresponding to a respective one of the n gamma-compensated reference voltages, and drive out the selected gamma-compensated source voltage. The lcd display driver includes a gamma reference circuit configured to generate the n gamma-compensated reference voltages based on at least one pre-defined gamma curve that includes n (0 to n−1) gamma-compensated reference voltage values divided into m regions defined by m+1 breakpoint voltages, including a range resistor string having a set of r voltage taps that are substantially uniformly spaced, and m+1 range/region digital-to-analog converters (dacs), where each range/region dac is coupled to a respective subset m+1 of the r voltage taps of the range resistor string, where at least some of the m+1 subsets of voltage taps overlap, and where each range/region dac is configured to output a respective breakpoint voltage based on the respective subset of voltage taps, including a breakpoint voltage bp(1) from range/region dac m=1 and a breakpoint voltage bp(m+1) from a range/region dac m+1, and including intermediate breakpoint voltages bp(2) to bp(m) from respective intermediate range/region dacs.

Image display device, correction data generation method, and image correction device and method, as well as image correction system


In the image display device, the vignetting pattern generator generates a vignetting pattern image composed of image data having inverted brightness characteristics obtained by inverting brightness characteristics of a panel of the liquid crystal display. The display controller carries out control to cause a pattern image obtained by combining a flat pattern image in gray composed of image data having a uniform grayscale level and the vignetting pattern image to be displayed on the liquid crystal display.
