Abstract: An apparatus for response time compensation includes a compression module, a decompression module, a display element response time compensation module, and a bypass control module. The compression module compresses a current frame to produce a compressed previous frame of image information. The decompression module decompresses the compressed previous frame of image information to produce a decompressed previous frame of image information. The display element response time compensation module provides display compensation information for a display based on the current frame and the decompressed previous frame. The bypass control module causes the current frame information to selectively bypass the compression module, the decompression module, and/or the display element response time compensation module based on display mode information.

Abstract: A liquid crystal panel displays an image from image signals. A backlight device is disposed on the back side of the liquid crystal panel, and is divided into a plurality of regions. The backlight device comprises light sources in each of the regions. The light sources are positioned to emit light onto the liquid crystal panel. A histogram detector detects an image signal gradation distribution for each region and to produce a histogram therefrom. An image gain calculator calculates a gain from the detected gradation distribution of the histogram detector, and controls light emission from each light source in each region of the backlight device. A light emission luminance calculator controls the light emission luminance of each light source based on a maximum luminance of the light sources and based on an inverse number of the gain calculated in the image gain calculator.

Abstract: A display has a spatial light modulator 10 for dynamically controlling a luminance of each pixel according to an input signal, the spatial light modulator having a non uniform spatial characteristic, the display also having an optical filter 20 having a spatial pattern to alter the luminance to compensate at least partially for the non uniform spatial characteristic. An electronic signal processing element applies some pre compensation predominantly of higher spatial frequencies for the non uniform spatial characteristic. Such dynamic and optical compensation can enable tuning for different optimizations or for compensating for variations over time. A backlight has an optical source and an optical filter, the source having a colour output which has a non uniform spatial characteristic, and the optical filter having a spatial pattern to alter the colour to compensate in part at least for the non uniform spatial characteristic.

Abstract: A display system that achieves a gamma characteristic different than 1, such as a gamma characteristic of 2 for example. The gamma characteristic may be selectable and it may be selectable via timing characteristics rather than by varying the intensity of the light source. Defective memory registers are also compensated for by selecting them to store bits of relatively lower significance.
