Abstract: Embodiments of the present invention relate to a display substrate and fabricating method thereof and a display device. The display substrate comprises a plurality of pixel groups, wherein each of said pixel groups comprises a plurality of color sub-pixels and a plurality of white sub-pixels. A first driving transistor is provided in a light emitting layer missing region of the color sub-pixel, for driving the color sub-pixel. A second driving transistor and a white sub-pixel are provided on the first driving transistor, the second driving transistor for driving the white sub-pixel. According to the technical solution, white light OLED display may be implemented by forming the white sub-pixel and the driving transistor thereof on the driving transistor of the color sub-pixel, while making use of the space on the thickness dimension of the color sub-pixel, so that the light emitting layer missing region in the color sub-pixel is fully utilized.

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 disclosure provides a detection circuit, a detection method and a drive system. The detection circuit comprises a switching unit, a reset unit and a comparison unit. The switching unit is used for switching the operations of the reset unit and the comparison unit. The reset unit is used for resetting the acquisition unit before the acquisition unit begins acquisition. The comparison unit is used for comparing a signal acquired by the acquisition unit with a standard signal to obtain a characterization quantity of the to-be-detected voltage.
