Problems solved by technology

However, because the principle of the anti-peep mechanism is to cause image changes when viewed from the side, the user will be more or less disturbed by the anti-peep mechanism when not looking directly at the display device 10, and see various anti-peep features on the screen. The special images caused by the peeping mechanism, such as mosaic grids, etc., will affect the smoothness of reading or work
As shown in the figure, in the display areas C1 and C2 where the viewing angle is greater than 10°, the user may start to feel various image interferences caused by the anti-peeping mechanism

Embodiment Construction

[0028] Please refer to figure 2 , which is a flow chart of the implementation steps of the image privacy protection method according to an embodiment of the present invention. The image privacy prevention method can be used in a display system including a display screen. The display system can be a single display screen, or a display device that can operate independently, or a multi-component system composed of a display screen and a computer host externally connected to the display screen to provide display data.

[0029] In this embodiment, it is first necessary to confirm the location of the anti-peeping image display area and the location of the normal image display area (step S200). After confirming the location of these two types of display areas, when processing images, the image data that will be displayed in the anti-peeping image display area and the image data that will be displayed in the normal image display area can be processed in different ways. processing t...

Abstract

Provided is an image anti-peeping method, comprising the following steps: firstly confirming the positions of the anti-peeping image display area and the normal image display area in the display system; processing the first image data displayed in the anti-peeping image display area in a narrow viewing angle mode to obtain the narrow viewing angle drive data and processing the second image data displayed in the normal image display area in a wide viewing angle mode to obtain the wide viewing angle drive data; and carrying out display operation in the anti-peeping image display area with the obtained narrow viewing angle drive data while carrying out display operation in the normal image display area with the obtained wide viewing angle drive data.

Description

technical field [0001] The present invention relates to a method for anti-peeping of an image, and particularly relates to a method for preventing a part of an image from being peeped. Background technique [0002] Generally speaking, in order to provide images to multiple viewers, a display device usually has a display effect with a wide viewing angle, but at certain times or occasions, such as when reading confidential information or entering a password, the display effect with a wide viewing angle is easy Make the confidential information be peeped by others and cause the leakage of the confidential information. Therefore, in order to meet the two different needs of providing multiple viewers and handling confidential information in public places, display devices with adjustable viewing angles that can switch between wide viewing angle mode and narrow viewing angle mode have gradually become one of the mainstream commodities in the display device market. . [0003] The ...
