  • Patent number: 10276085
    Abstract: This application relates to systems, methods, and apparatus for compensating voltage for pixels of a display panel based on the location of the pixels within the display panel. An amount of voltage compensation is assigned to each pixel or a group of pixels within the display panel in accordance with a calibration of the display panel. During operation of the display panel, pixel data is generated for a location of the display panel, and the pixel data is modified according to the amount of voltage compensation corresponding to the location. By modifying the pixel data in this way, spatial variations in voltage across the display panel can be mitigated in order to reduce the occurrence of certain display artifacts at the display panel.

    Abstract: A display panel of a liquid crystal display device includes smoothing parts provided on an output end side of auxiliary capacitance lines. Through the smoothing parts, the auxiliary capacitance lines arranged along scanning signal lines and a common electrode are connected to each other. The smoothing parts each have a correction TFT and a capacitor. A source electrode of the correction TFT and each of the auxiliary capacitance lines are connected to each other, and a drain electrode and the common electrode are connected to each other through each of the capacitors. The correction TFT is controlled so as to enter a conductive state when the scanning signal line is in a selected state, and enter a shut state when the scanning signal line is in a non-selected state.

  • Patent number: 8570319
    Abstract: Where images are displayed such that unintended light is also included and that light cannot be fully subtracted from the displayed image, an image processor compensates by compensating for the remaining light using perceptual models. In some cases, the perceptual model includes a plurality of user sensitivities and computation is performed, at least in part, based on expected user sensitivity to light pollution in portions of the images. The perceptual model might include a contrast sensitivity function, threshold-vs-intensity, saliency prediction and visual masking. The model might include artist indications of view attention. A light pollution likelihood map might be used to reduce the amount of computation needed, using a likelihood measure to determine an amount of computation to perform.

  • Publication number: 20130278650
    Abstract: In the present display device, LEDs are controlled to be lit up in an alternating manner where BG-LEDs (34) and BR-LEDs (35) are controlled to be lit up alternatingly every half of one frame period, such that only G display elements are used for display in a first subframe where the BG-LEDs (34) are lit up, and only B and R display elements are used for display in a second subframe where the BR-LEDs (35) are lit up. As a result, even in the case where crosstalk occurs (with respect to color filters of a certain color), display elements of colors for which such crosstalk can be inhibited or eliminated are simply used for display so that a reduction in color reproducibility can be inhibited or eliminated.
