Abstract

The embodiment of the invention discloses a display brightness adjusting method and device and aims at solving the technical problems that existing pure manual adjustment is inconvenient, the display brightness is purely automatically adjusted, the display brightness is different under the condition of the same environment light illumination intensity due to the difference of various hardware and structures and different equipment; manual adjustment and automatic adjustment are combined and are mutually independent, and only one of the manual adjustment and automatic adjustment can be selected essentially. The method provided by the embodiment of the invention comprises the following steps: starting an automatic brightness adjusting mode so that brightness automatic adjustment of a display screen is carried out; when obtaining a second triggering instruction of a manual brightness adjusting mode, judging that the second triggering instruction is a brightness increasing instruction or a brightness decreasing instruction; if the second triggering instruction the second triggering instruction, increasing the brightness by carrying out an adjusting degree corresponding to the brightness increasing instruction based on a current brightness state; and if the second triggering instruction is the brightness decreasing instruction, decreasing the brightness by carrying out the adjusting degree corresponding to the brightness decreasing instruction based on the current brightness state.

Description

[0001] This application is based on the Chinese patent application number 201410609382.8, the applicant is Huizhou Huayang Multimedia Electronics Co., Ltd., and the name is "a HUD and its control method" as the priority document. technical field

[0002] The invention relates to the technical field of vehicle communication, in particular to a method and device for adjusting display brightness. Background technique

[0003] Car HUD (Head-Up-Display), also known as head-up display, uses the principle of reflection to project information such as navigation and driving on the windshield or a transparent reflective screen in front of the windshield. The image the driver sees is a virtual image, as if floating in the air. In this way, the driver can see the information within the normal driving line of sight, reducing the time for the driver to take his eyes off the road to check the information, thereby effectively improving driving safety. At the same time, due to the rapid deve...
