Abstract

The invention provides a control method and device which are applied to a vehicle with a head-up display, the head-up display comprises a lens and a display screen which are connected with each other,and the method comprises the steps that when the vehicle is in a remote state, the working mode of the head-up display is obtained; and under the condition that the working mode is a first working mode, the lens is controlled to be in an initial state and the display screen is controlled to be in a screen-off state. When the vehicle is in the remote state, the display screen of the head-up display of the vehicle is controlled to be turned off, electric energy consumption can be reduced, and the lenses are in the initial state, so that external light cannot be gathered on the display screen ofthe head-up display; and the situation that the liquid crystal screen is ablated and damaged due to over-high temperature of the display screen caused by external light is avoided.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a control method and device. Background technique [0002] As a common means of transportation, automobiles occupy an increasingly important position in the transportation field, and the requirements for display functions of automobiles are gradually increasing, and windshield-type head-up displays (Windscreen Head Up Display, WHUD) with display functions are also applied. [0003] At present, WHUD uses optical principles to project driving information to the front windshield. However, when the vehicle is in a remote state, the driver is usually not in the vehicle, while the WHUD is in a normal working state, resulting in increased power consumption, and if the vehicle is stationary for a long time, The external light converging on the LCD screen of the WHUD may cause the temperature of the LCD screen to be too high, further causing the LCD screen to be ablated and damag...
