Abstract

The embodiment of the invention provides a control method, a device, equipment and a backlight module. The control method comprises the steps of acquiring a touch instruction sent by a user to the display equipment, wherein the touch instruction comprises a touch point of the user to the display equipment; determining a local area where the touch point is located in the display device; and lowering the brightness of the local area where the touch point is located. According to the method, when the user sending the touch instruction watches the display equipment, the sight line is concentratedin the local area where the touch point is located through the touch instruction, and then the brightness of the local area where the touch point is located is lowered, so that the user close to the display equipment cannot feel dazzling due to too high brightness; and a user far away from the display equipment can see the display content on the display equipment clearly, so that the visual experience of the user is improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a control method, device, equipment and a backlight module. Background technique [0002] At present, in public areas such as classrooms and conference rooms, interactive display devices are often provided for writing and communicating. [0003] Taking the electronic whiteboard installed in the classroom as an example, for the viewer, the farther away from the electronic whiteboard, the worse the viewing effect. In order to enable viewers who are far away from the electronic whiteboard to see clearly the writing on the electronic whiteboard, it is necessary to brighten the electronic whiteboard. However, if the brightness of the electronic whiteboard is increased, it will cause the viewers who are closer to the electronic whiteboard (such as teachers who write on the blackboard) to feel glare. [0004] Therefore, how to improve the user's visual experience on the display d...
