  • Patent number: 10388216
    Abstract: A display device includes an image controller that analyzes first image data to determine whether a same image is displayed for no less than a predetermined threshold time. The image controller sets a low grayscale region having grayscale values of no more than a predetermined threshold low grayscale value when the same image is displayed for no less than a threshold time. The image controller then receives second image data and transmits a control signal to allow a transistor hysteresis reset signal to be transmitted to pixels of the display in the low grayscale region. A data driver transmits the transistor hysteresis reset signal to the pixels in the low grayscale region based on the control signal.

    Abstract: Systems, methods, and computer-readable media are disclosed for generating a holographic masking surface to obscure content displayed on a user device from view of third parties. At least one of a gaze direction of a user of the user device or a direction of interaction of the user with the user device is detected and user interaction data indicative thereof is generated. A set of holographic projectors to activate is then determined based at least in part on the user interaction data, and a holographic masking surface is generated at least in part by activating the set of holographic projectors. A gaze direction of a third party proximate to the user device may also be determined such that the holographic masking surface is generated when the third party is viewing or potentially can view the display of the device and the content being displayed is confidential in nature.

  • Patent number: 10319319
    Abstract: The present disclosure relates to a substrate and a liquid crystal display. The substrate includes a plurality of data lines, scanning lines, and pixel cells arranged in a matrix. Each of the pixel cells includes a first sub-pixel and a second sub-pixel. For the pixel cells in each row, a first sub-pixel of a pixel cell connects with the two scanning lines. The second sub-pixel of the pixel cell connects with one of the scanning line. When the pixel cells are driven, durations of the turn-on signals outputted by the two scanning lines connected with the pixel cell are different or the turn-on signals are asynchronous. As such, a turn-on period of the second sub-pixel of the pixel cell connecting with the data line is longer than the turn-on period of the first sub-pixel connecting with the corresponding data line. In this way, the color shift may be reduced.
