The invention discloses a display panel, a display device and a preparation method of the display panel. The display panel comprises a substrate, a pixel definition layer, a pixel electrode and a protection layer. The pixel defining part of the pixel defining layer is enclosed to form a pixel opening. The orthographic projection of the protective layer on the substrate is at least partially overlapped with the overlapping area, and the protective layer can cover at least part of the pixel electrode exposed out of the pixel opening, so as to reduce the residue of the pixel defining material on the surface of the part of the pixel electrode exposed out of the pixel opening; in the subsequent process, a relatively strong plasma photoresist removing process is adopted to remove the pixel definition material, and the protection layer covers at least part of the pixel electrode, so that the problem that the pixel electrode is damaged due to the relatively strong plasma photoresist removing process can be improved, and the device performance of the pixel electrode is ensured; in addition, the problems that the surface roughness of the pixel electrode is increased, the reflectivity is reduced and the image quality of the display panel becomes poor due to the fact that the pixel defining material is left on the surface of the pixel electrode can be avoided, and therefore the use performance of the display panel is improved.

The present application relates to the technical field of image processing, and discloses an image processing method and device, a vehicle, a storage medium and a program product, wherein the present application determines the scene label of a target driving scene by acquiring multi-modal environment perception data. Then, the joint parameter mapping table is queried based on the scene label to match the target joint parameter corresponding to the target driving scene, the target joint parameter including a pair of first parameter group and second parameter group, and the synergistic constraint relationship existing between the first parameter group and the second parameter group can effectively inhibit the gain conflict caused by the opposite image gain trend of the two groups of parameters. The first parameter group and the second parameter group are used to control the first image processor and the second image processor to perform image processing and optimization in turn to obtain a target image, and the algorithm synergistic processing of the image acquisition end and the image display end is established, so that the picture quality degradation caused by algorithm conflict is avoided while adapting to various driving scenes, and the display effect of the vehicle-mounted image is significantly improved.

A reduction in image quality is suppressed while a reduction in transfer efficiency is suppressed.
