The embodiment of the invention provides a head-up display device, a vehicle and a control method of the head-up display device.The head-up display device comprises an image source and a reflection imaging part, the image source is used for emitting image light, and the reflection imaging part is used for reflecting the image light into an eye box area corresponding to the head-up display device. The image source comprises a liquid crystal display screen and a plurality of backlight lamps, the backlight lamps are installed on the back side of the liquid crystal display screen and used for providing backlight for the liquid crystal display screen so that the liquid crystal display screen can emit the image light rays, the brightness of at least one backlight lamp in the backlight lamps can be independently adjusted, and the brightness of the backlight lamps can be independently adjusted. And the heat received by the liquid crystal display screen from the backlight lamp is reduced.

The utility model discloses a touch display screen of a silicon-based OLED (Organic Light Emitting Diode), which comprises a glass substrate and a groove arranged at the bottom end of the glass substrate, an adjusting mechanism is arranged in the groove, an electronic board connected with the adjusting mechanism is arranged at the bottom end of the adjusting mechanism, a light-emitting layer contacted with the groove is arranged at the top end of the groove, a conducting layer is arranged on the electronic board, and a light-emitting layer is arranged on the conducting layer. And an oleophobic layer is arranged at the top end of the glass substrate. The beneficial effects are that the signal relay is arranged to ensure that the light emitting layer is not lightened when the glass substrate is contacted for a short time or the glass substrate is contacted by mistake, so that the energy loss can be reduced, and the OLED screen is easy to burn, so that under the action of the pressure sensing layer and the temperature detection layer, the OLED screen can be effectively protected. When the pressing signal and the temperature difference signal cannot be detected, the power line connected with the light-emitting layer can be automatically cut off, so that the burn-in phenomenon is avoided, and the service life of the product is prolonged.

The present invention provides an aromatic compound for a liquid crystal aligning agent, the aromatic compound being used for obtaining a liquid crystal aligning agent having a high voltage holding ratio and good liquid crystal aligning properties in a harsh environment even in the case of an alignment treatment using a photo-alignment method in which a chemical change is caused by irradiation with radiation or the like. The liquid crystal display element is capable of suppressing burn-in that occurs in liquid crystal display elements of IPS and FFS methods. The aromatic compound for the liquid crystal aligning agent is any one selected from the group consisting of formulae (b-1) to (b-4). # imgabs0 #

The invention relates to a cooling system, an image generation unit and a head-up display device. In one aspect, a cooling system is provided that includes a cooling body for being disposed at and in contact with a back surface of a display panel of a head-up display device, the cooling body having a hollow structure for a cooling liquid to flow therethrough, and the cooling body being made of a transparent material. Therefore, the temperature of the display panel can be effectively reduced under the condition that normal display and work of the head-up display are not influenced.

The invention relates to an image processing method and device, electronic equipment and a readable storage medium, and relates to the technical field of terminal display. Comprising the steps that gray scale gain curves corresponding to different screen loads are acquired, and the gray scale gain curves are used for representing the relation between different gray scales and gray scale gain values; according to the plurality of gray-scale gain curves, obtaining a target gray-scale gain curve corresponding to a target screen load, the target screen load being a screen load required by the terminal to display the to-be-compensated image; and compensating the gray scale in the image to be compensated by adopting the target gray scale gain curve to obtain a compensated image. By using the image processing method provided by the invention, the gray scale in the to-be-compensated image can be compensated by using the accurate gray scale compensation value when the screen load changes, so that the influence of voltage drop on the display effect can be reduced while the burn-in phenomenon is avoided.
