摘要： A self-monitoring method of a display and a display are disclosed. The self-monitoring method of a display includes: inputting a first image test signal; acquiring a display parameter of the first image test signal; acquiring a first display parameter of at least one frame of image outputted, based on the first image test signal, by the display, in which each frame of image of the at least one frame of image corresponds to a corresponding first display parameter; comparing the display parameter of the first image test signal with the first display parameter, determining whether or not an image displayed by the display is matched with the first image test signal so as to acquire a first match result; and determining whether or not display abnormality presents in the display based on the first match result. The method can determine whether or not display abnormality presents in the display.

摘要： The present invention discloses a local backlight brightness adjustment method for a direct backlight in a display device, the method comprising the steps of: step 1: performing edge detection on an input image to determine whether a sensitive zone exists, the sensitive zone being a portion in the input image in which a gray level difference between adjacent pixels is greater than a predetermined threshold; and Step 2: if a sensitive zone exists, performing a backlight brightness adjustment with respect to a backlight region corresponding to the sensitive zone and a remaining backlight region other than the backlight region corresponding to the sensitive zone, respectively. According to the above-mentioned technical solution, since the backlight brightness adjustment are performed with respect to the backlight region corresponding to the sensitive zone and the remaining backlight region other than the backlight region corresponding to the sensitive zone, respectively, thus, when there is gray level abruptly-varying portion in the image, the display performance of the displayer can still be ensured.

摘要： A display panel, a manufacturing method and driving method thereof are provided. The display panel includes a light transmittance adjusting layer and two pixel layers being respectively located on opposite surfaces of light transmittance adjusting layer. Each pixel layer includes multiple light-emitting units arranged in an array. Orthogonal projections of two pixel layers on the light transmittance adjusting layer do not overlap. When light transmittance of light transmittance adjusting layer is higher, light emitted from the light-emitting units on both surfaces of light transmittance adjusting layer is emergent from opposite sides through light transmittance adjusting layer. Two pixel layers display the same picture jointly. When light transmittance of light transmittance adjusting layer is lower, light emitted from light-emitting units on both surfaces of light transmittance adjusting layer cannot be transmitted through light transmittance adjusting layer to reach opposite sides. Two pixel layers display images independently.
