  • Patent number: 10388206
    Abstract: The present invention provides a pixel array comprising a plurality of pixel units, each of which comprises three sub-pixels in different colors, wherein, in each pixel unit, any two adjacent sub-pixels are combined into a pixel block. Compared to the prior art, the width of the sub-pixel in the present invention increases, which reduces the difficulty of the manufacturing process of the pixel array and improves product yield. The present invention further provides a driving method of the pixel array, a display panel including the pixel array, and a display device including the display panel. When driving the above pixel array with the driving method, granular sensation of the display panel including the pixel array can be reduced, and a display effect of a display panel with higher resolution in the same size can be achieved.

  • Patent number: 9818605
    Abstract: An Oxide TFT, a preparation method thereof, an array substrate and a display device are described. The method includes forming a gate electrode, a gate insulating layer, a channel layer, a barrier layer, as well as a source electrode and a drain electrode on a substrate; the channel layer is formed by depositing an amorphous oxide semiconductor film in a first mixed gas containing H2, Ar and O2. By depositing a channel layer in a first mixed gas containing H2, Ar and O2, the hysteresis phenomenon of the TFT can be mitigated effectively to improve the display quality of the display panel.

  • Patent number: 9613564
    Abstract: The present disclosure relates to an image displaying method and a display apparatus wherein each of raw pixels is divided into a plurality of virtual pixels based on desired image resolution for displaying a frame to be displayed; virtual image information for each of the virtual pixels is determined based on weights of the respective sub-pixels in each of the virtual pixels, weights of the respective sub-pixels in the virtual pixels which are adjacent in rows and the received original image information; thus, each of the virtual pixels displays a color(s) which it lacks itself with the aid of the respective sub-pixels in the virtual pixels which are adjacent in rows, so that the same display function as that of each of the raw pixels may be implemented, and thus the image resolution of the frame to be displayed is increased.

  • Patent number: 8766895
    Abstract: The invention relates to a driving method, compensation processor and driver device for liquid crystal display. The driving method includes steps of receiving data signal of a present frame; obtaining an average brightness value of the present frame; comparing the previous frame with the present frame, and when the difference between the average brightness values is larger than or equal to a set threshold, generating at least two back light driver pulse signals of which the duty ratios gradually changing, and outputting them to drive the back lights. The compensation processor includes a data analysis module, a data compensation module, a back light linear filtering module and a pulse generator module. The driver device employs the compensation processor of the present invention.
