Screen control method of display device, screen control device of display device and display device

Abstract

The embodiment of the invention provides a screen control method of a display device, a screen control device of the display device and the display device, and relates to the technical field of a flexible display device. The problems of high display power consumption and poor user experience of a flexible screen of the existing display device can be solved. The method comprises the following stepsthat when the flexible screen is pulled out from a roll or is collected into the roll, three detection light blocks positioned in a roll outlet position on the flexible screen are illuminated; the three detection light blocks are distributed in the pulling-out direction of the flexible screen; the brightness is sequentially enhanced or sequentially weakened; the position of the detection light block positioned in the middle is right aligned with the position of a photoelectric sensor; when the photoelectric sensor detects that the light intensity increases or decreases, the positions of the three detection light blocks are updated, so that the position of the detection light block positioned in the middle is right aligned with the position of the photoelectric sensor; and the part positioned at one side, far away from the detection light block with the highest brightness, of the detection light block with the weakest brightness on the flexible screen is controlled to be illuminated, and other parts of the flexible screen are controlled to be turned off. The invention is used for a flexible display device.

Description

technical field [0001] The present invention relates to the technical field of flexible display devices, in particular to a method for controlling a screen of a display device, a control device thereof, and a display device. Background technique [0002] With the development of science and technology and the popularization of flexible screens, mobile phones with rolling screens have gradually become a research hotspot. Existing roll-screen mobile phones generally display images when the flexible screen is fully pulled out, and close when the flexible screen is fully retracted into the reel, and cannot detect the length of the flexible screen in real time, let alone control the image displayed on the part of the flexible screen in real time. Or control the part of the flexible screen retracted into the reel to turn off the image in real time, so that the display power consumption of the flexible screen is high and the user experience is poor.

Problems solved by technology

[0003] Embodiments of the present invention provide a screen control method of a display device, its control device, and a display device, which can solve the problem that the existing display device cannot control the flexible screen to pull out a part of the displayed image in real time or control the flexible screen to be retracted into the reel in real time. Part of the image is turned off, resulting in high power consumption of the flexible screen and poor user experience
