Display device and operating method thereof
A display device that achieves both high detection sensitivity of the touch sensor unit and smooth input on the touch sensor unit is provided. A method for driving a display device includes a first period and a second period. The display device includes pixels, a gate driver, and a touch sensor unit. The touch sensor unit detects a touch in the first period and stops detecting a touch in the second period. The gate driver supplies signals to some of the pixels and does not supply signals to the other pixels in the second period.
Backlight unit and control method thereof, and liquid crystal display device
The present invention provides a backlight unit and a control method thereof, and a liquid crystal display device. The control method includes steps as follows: obtaining backlight data corresponding to each partition, wherein the backlight data comprises a plurality of bits of data; dividing the light-emitting unit of each partition into a plurality of subfields with different durations in a light-emitting process during a frame, wherein each subfield corresponds to one bit of data, and any two subfields comprise different numbers of secondary subfields; and outputting the plurality of subfields in a preset order.
VECTOR DITHERING FOR DISPLAYS EMPLOYING SUBFIELDS HAVING UNEVENLY SPACED GRAY SCALE VALUES
This disclosure provides systems, methods, apparatus, and computer readable media for generating images on a display using a dithering process that takes into account an uneven spacing of available gray scale values in at least one color subfield used to generate the images. The dithering process includes generating a set of initial color subfields, a set of quantized color subfields, and a set of final color subfields, which are then output on the display. The quantized color subfields an the final color subfields are derived based at least in part on the uneven spacing of gray scale values in at least one of the final color subfields.
Display device driving method
The present invention provides a method of driving a display device, comprising the steps of: step S1, providing a display device, comprising a plurality of sub-pixels arranged in an array; step S2: dividing data signals of the sub-pixels in a frame of an image into a plurality of sub-frames having different time weights; step S3, dividing the plurality of sub-pixels into at least two driving groups, and the plurality of sub-frames corresponding to the sub-pixels in different driving groups having different display order; and step S4, driving each of the sub-pixels to display image according to a display order of one of the sub-frames corresponding to each of the sub-pixels, such that through setting different display order of sub-frames of the sub-pixels of different driving groups, the flicker caused by the digital driving can be reduced without increasing driving frequency.

Pan-warping and modifying sub-frames with an up-sampled frame rate
In an embodiment, a method includes accessing a first rendered frame generated based on a first viewing direction of a user. The first rendered frame may be generated at a first frame rate. The method includes generating, based on the first rendered frame, one or more sub-frames at a second frame rate that is higher than the first frame rate. A first sub-frame of the one or more sub-frames is generated by determining a second viewing direction of the user based on sensor data and applying one or more transformations to the first frame based on the second viewing direction. The method includes outputting the one or more sub-frames for display at the second frame rate.
BACKLIGHT UNIT AND CONTROL METHOD THEREOF, AND LIQUID CRYSTAL DISPLAY DEVICE
The present invention provides a backlight unit and a control method thereof, and a liquid crystal display device. The control method includes steps as follows: obtaining backlight data corresponding to each partition, wherein the backlight data comprises a plurality of bits of data; dividing the light-emitting unit of each partition into a plurality of subfields with different durations in a light-emitting process during a frame, wherein each subfield corresponds to one bit of data, and any two subfields comprise different numbers of secondary subfields; and outputting the plurality of subfields in a preset order.
Display apparatus
Setting of an order of sub-frame periods is simplified. A display element array section includes a plurality of arranged display elements in which a gray-scale display is performed in accordance with display data in each frame period that is a display period of one screen. A display control section divides the frame period into a plurality of sub-frame periods and divides the plurality of display elements into a plurality of groups to perform control of a display in each of the plurality of sub-frame periods in each of the plurality of groups. A display data supply section supplies the display data in each of the sub-frame periods to the display element array section by shifting a predetermined delay time in each of the groups and supplies the display data in each of the sub-frame periods to the display element array section on the basis of an order of the sub-frame periods in accordance with the number of the divided groups and the predetermined delay time.
Pan-warping and modifying sub-frames with an up-sampled frame rate
In an embodiment, a method includes accessing a first rendered frame generated at a first frame rate. The method includes generating, based on the first rendered frame, one or more sub-frames at a second frame rate that is higher than the first frame rate. A first sub-frame of the one or more sub-frames is generated by determining a displacement measure associated with an anticipated movement of an optics component of a display system and applying, based on the displacement measure, one or more transformations to the first rendered frame to generate the first sub-frame. The first sub-frame is to be perceived by a user using the optics component of the display system. The method includes outputting the one or more sub-frames for display at the second frame rate. The one or more sub-frames are perceived by the user using the optics component of the display system.
