    Abstract: A circuit and method facilitate driving a display panel to display an image with improved brightness uniformity are disclosed. In the circuit, an image information extraction sub-circuit extracts, and sends to a compensation processing sub-circuit, display information of each of the plurality of pixels based on the image. The compensation processing sub-circuit then divides a display region of the display panel into a plurality of sub-regions, obtains an average brightness value of each sub-region, and further determines whether a compensation is needed for displaying the image based on a uniformity of the average brightness values of all sub-regions. If so, the compensation processing sub-circuit further performs compensation to an input voltage and/or an effective light output area of each of the pixels to be lightened in each sub-region to thereby obtain an improved brightness uniformity when displaying the image.

    Abstract: Disclosed are an organic electroluminescent display and a method for preparing the same, and a display device. The organic electroluminescent display comprises: a base substrate; an organic electroluminescent pixel array, which is set on the base substrate; a packaging coverplate or a packaging film, which is covered outside the organic electroluminescent pixel array; and a phase difference film and a polarization functional film located inside the packaging coverplate or the packaging film and attached to the organic electroluminescent pixel array in turn. In the organic electroluminescent display according to the invention, the unnecessary films, such as a TAC films that need to be attached to the two sides of a polarization functional film in an existing circular sheet polarizer and a binding agent layer, etc., can be omitted, thereby the transmittance of a display can be improved, and the contrast of a display can be increased; moreover, the overall thickness of a display may be reduced, and the problem of being difficult to roll up may be avoided; and there exists no interference of oxygen and aqueous vapor, thus the durability of the circular sheet polarizer can be increased.
