    Abstract: A method including receiving a first row of display data for a first time period, and determining a value of a specified bit position for first portions of a first plurality of multi-bit portions in the first row. The method further includes receiving a second row of display data for a second time period, and determining a value of the specified bit position for second portions of a second plurality of multi-bit portions in the second row. Based on the determining, identifying second portions that indicate a change in the value of the specified bit position from the first time period to the second time period, and identifying an output channel associated with each identified portion. The method further includes grouping each identified output channel into a first or second group based on a polarity type, and connecting the identified output channels together within each group.

    Abstract: A display apparatus includes a display panel, a memory, a bit-data convertor, a switch, and a gate driver. The display panel includes pixels. Each pixel is connected to one of the data lines and one of the gate lines. The memory stores a plurality of image data corresponding to a frame period. The bit-data convertor determines a plurality of bit data. Each of the bit data corresponds to a degree of change between adjacent image data among the plurality of image data, obtains a sum of the bit data, and outputs the sum of the bit data as a total count bit data value. The switch outputs a first pulse control signal corresponding to the total count bit data value. The gate driver generates a gate signal based on the first pulse control signal, and to output the gate signal to one of the gate lines.

    Abstract: A display substrate, a driving method thereof and a display device are disclosed. The display substrate includes repeatedly arranged pixel groups. Each pixel group includes a first sub-pixel group, a second sub-pixel group, a third sub-pixel group and a fourth sub-pixel group. Each of the first sub-pixel group, the second sub-pixel group, the third sub-pixel group and the fourth sub-pixel group includes four pixel columns. The display substrate, the driving method thereof and the display device reduce the number of sub-pixels in the whole display device and hence reduce the difficulty in the manufacturing process of the display device and the cost on the premise of ensuring that the display device obtains a high resolution.

    Abstract: A display device including: a light emitting unit including a plurality of light sources; a second panel configured to adjust transmittance of light from the light emitting unit; and a first panel configured to adjust transmittance of light from the second panel, further including: a first control unit configured to perform first control with respect to the first panel for controlling transmittance of each pixel on the basis of the image data; and a second control unit configured to perform, in a case where an image area of low brightness is adjacent to an image area of high brightness in the image data, second control for making transmittance of the second panel at a partial area corresponding to the image area of low brightness be lower than transmittance of the second panel at a partial area corresponding to the image area of high brightness.

    Abstract: A display may have a first stage such as a color liquid crystal display stage and a second stage such as a monochromatic liquid crystal display stage that are coupled in tandem so that light from a backlight passes through both stages. The first (upper) stage may be a high resolution display panel that is operated at a first refresh rate while the second (lower) stage is a low resolution display panel that is operated at a second refresh rate that is greater than the first refresh rate. In particular, the second stage may be configured to provide localized dimming that is synchronized to one or more moving objects in the video frames to be displayed to help reduce the perceived motion blur. The localized dimming may be provided via insertion of a black image portion that only overlaps with the moving objects, a blanking row that tracks the moving objects, a black frame, etc.
