[0094] This embodiment is an extension of the aforementioned first embodiment. The control method of the display device in this embodiment includes:

[0095] S21. The image processor receives the original image data, and divides a frame of image into N image columns according to the column direction, where N is a positive integer greater than or equal to 2;

[0096] S22. The image processor generates a first image and a second image according to the N image columns, and generates brightness information of each image column according to the N image columns, and each image includes N data columns;

[0097] S23. The image processor sends the first image, the second image and brightness information to the display controller;

[0098] S24. The display controller generates a first grating driving signal and a second grating driving signal according to the first image and the second image respectively, and generates a first brightness driving signal and a second brightness driving s...

Abstract

The embodiment of the invention provides a display device and a control method thereof. The control method of the display device comprises the steps that an image processor divides a frame of image into M images and sends the M images to a display controller, wherein the M is an even number larger than or equal to 2; and the display controller controls the display panel to sequentially display the M images in a frame period, and controls the grating panel to sequentially form grating patterns corresponding to the M images in the frame period. The invention discloses a double-layer panel structure based on a grating panel and a display panel. A frame of image is displayed in multiple times in a frame period, and grating patterns corresponding to the images displayed for multiple times are formed in sequence through time-sharing control, peep-proof display is achieved, switching between the peep-proof display mode and the shared display mode is achieved, and the display device has the advantages of being small in brightness loss, high in display resolution ratio, free of loss of peep-proof display state images and the like.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display device and a control method thereof. Background technique [0002] With the continuous development of display technology, people have more and more diverse demands on display methods, and at the same time, users have a stronger awareness of personal privacy protection, and more and more scenarios require display devices to have anti-peeping functions. For example, in the field of business display, there are display requirements such as portability, privacy protection, and high color gamut and high contrast. Therefore, privacy protection technology has become an important content of high-end business notebooks as a privacy protection method. [0003] At present, in order to satisfy the anti-peeping function, various solutions have been proposed in related technologies. The inventors of the present application have found through research that these solutions all...
