    Abstract: The present disclosure provides a pixel structure, a display panel, and a display apparatus. The pixel structure includes a plurality of subpixels. The subpixels include red subpixels, green subpixels, and blue subpixels. The red subpixels and the green subpixels are all substantially in an isosceles triangular shape and have substantially a same area. Each blue subpixel is in substantially a rhombic shape and has an area substantially twice the area of the red subpixel or green subpixel. Each leg of the isosceles triangular shape of the red or green subpixel has a length equal to a side length of the rhombic shape of the blue subpixel. The display panel using the subpixel rendering algorithm has visual resolution greater than physical resolution. The enlarged blue subpixel extends life span to make all three color subpixel have similar life span.

    Abstract: The present disclosure provides an OLED array substrate, and a display panel and a display device including the OLED array substrate. A VDD grid is provided in an existing AMOLED array substrate with a compensation function, VDD lines are connected with the VDD grid via switches, which are applied with corresponding voltages to be switched on during a light emitting stage, such that the VDD lines are electrically connected in parallel to the VDD grid, thus a total resistance of the VDD lines and the VDD grid connected in parallel is decreased relative to the own resistance of the VDD line, so as to reduce the voltage drop on the VDD line in a direction in which the scanning control lines extend, and in turn to decrease a variation in a OLED driving voltage signal effectively, ensuring uniformity of luminance across the display area.

    Abstract: An array substrate and a fabrication method thereof, and a display device are provided. The array substrate comprises: a pattern of an organic light-emitting layer (11); a pattern of an active layer (4a) located in a thin film transistor region and a pattern of an absorbing layer (4b) located in an open region, which are arranged in a same layer, wherein, the pattern of the absorbing layer (4b) is located in a light outgoing direction of the pattern of the organic light-emitting layer (11), and is made of a transparent material having an ultraviolet absorbing function. In this way, the pattern of the absorbing layer located in the open region can absorb ultraviolet light from outgoing light, so that damage to eyes caused by the outgoing light can be reduced; and the pattern of the active layer and the pattern of the absorbing layer are arranged in a same layer, which, as compared with a manner of separately arranging a layer of an ultraviolet absorbing layer in the array substrate, can reduce a thickness of the array substrate, which is conducive to lighting and thinning a display device.
