Abstract

The invention provides a display panel and a manufacturing method thereof and a method for driving the display panel. The display panel comprises an array substrate and a controller, wherein a plurality of pixel units are arranged on the array substrate; light-emitting elements are arranged in the pixel units; reflective layers and optical sensors electrically connected with the controller are arranged in at least a part of the pixel units; the reflective layers are arranged in the light-emitting directions of the light-emitting elements and used for reflecting the emergent light emitted fromthe light-emitting elements to the optical sensors; the optical sensors are used for measuring the real-time intensity of the reflected light; and the controller is used for adjusting the light-emitting intensity of the light-emitting elements to approach the theoretical intensity according to the real-time intensity. The display panel has the beneficial effects that the real-time compensation ofthe emergent light emitted from the light-emitting elements of the pixel units can be realized; the defect of poor display effect due to aging or badness is overcome; a good display effect can still be realized after long-time use; and the structure is simple and the overall structure of the display panel needs not to be changed, so that the display panel is easy to realize in process and the industrial production is easy.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a display panel, a manufacturing method thereof, and a method for driving the display panel. Background technique [0002] In the related art, after the display panel is put into use, poor display will be caused due to defective array (array substrate) or aging; in addition, as the use time of the display panel increases, different pixels will have different aging degrees, which will also lead to poor display. At present, the method to solve the above-mentioned poor display is mainly to use the CCD (electrical coupling device) to perform a pixel (pixel)-level precise optical calibration directly after the Gamma (gamma) debugging is performed when the display panel leaves the factory; The external circuit of the panel performs external circuit compensation to compensate for the shift of Vth (threshold voltage). However, none of the aforementioned methods can realize the...
