  • Patent number: 10977981
    Abstract: Embodiments of the present disclosure provide a device for controlling luminance, a method of controlling luminance and a display device. The method of controlling luminance may comprise: obtaining a theoretical white balanced luminance value for each color of sub-pixel included in N pixels; obtaining a luminance controlling value for other colors of sub-pixels except for a ith color of sub-pixel included in each of the N pixels; and adjusting luminance of the other colors of sub-pixels except for the ith color of sub-pixel included in each pixel according to the luminance controlling value. The method of controlling luminance can be used in luminance controlling devices.

  • Patent number: 10930224
    Abstract: The present disclosure provides a method of eliminating a black border of a display device, a display device and a detecting device. The display device includes a cover plate and a display panel, which are configured in a stack; the cover plate includes a light transmissive region and a non-light transmissive region located around the light transmissive region. The display panel includes a display area corresponding to the light transmissive region. The display area includes a first sub-display area and a second sub-display area around the first sub-display area. A size of the display area is greater than a size of the light transmissive region of the cover plate and pixels of the second sub-display area on at least one side are configured to display the same color as the color of the non-light transmissive area.

  • Patent number: 10629633
    Abstract: A manufacturing method of an array substrate is disclosed. The manufacturing method includes a step of forming a pattern including a pixel electrode; and the manufacturing method further includes a step of forming a pattern including an active layer after the step of forming the pattern including the pixel electrode. Accordingly, an array substrate and a display device are also disclosed. In the manufacturing process of the array substrate, conductive material remained on the active layer is less, thereby producing less leak current, which in turn improves quality of the array substrate and display performance of the display device.
