Anti-peeping method and 3D stereoscopic display device

Abstract

The invention provides a peep-proof method and a 3D display device. The peep-proof method is applied in a 3D flat panel display with a 3D glass. The 3D glass comprises a left eye polarizing filter and a right eye polarizing filter. With this method, a first image is output to an odd row pixel of the 3D flat panel display, and a first light source of the odd row pixel is controlled to polarize towards a first direction, and the odd row pixel can display the first image towards the first direction. A second image different from the first image is output to an even row pixel, and a second light source of the even row pixel is controlled to polarize towards a second direction, and the odd row pixel can display the second image towards the second direction. The left and right eye polarizing filters of the 3D glass are both rotated towards the first direction, and thereby the first image is received and the second image is obstructed. Accordingly, a user wearing a 3D glass can clearly see the first image, but a user with naked eyes cannot clearly see the first image due to the interference of the second image, and peep-proof purpose can be realized.

Description

technical field [0001] The invention relates to a peep prevention method, in particular to a peep prevention method utilizing 3D display technology and a 3D stereoscopic display device. Background technique [0002] When most people use their laptops in public places, they are always worried that others will peep at the screen of the laptop. Therefore, based on the need for privacy or confidentiality, some people will buy anti-peep stickers to stick on the screen of the laptop . However, privacy patches may have the following disadvantages: [0003] 1. Cannot be completely anti-peep: the anti-peep patch provides a viewing angle of about 60 degrees, so other people within the viewing angle can still see the content on the screen. [0004] 2. Inconvenient to use: When you need to watch the screen with others, you need to remove the anti-peeping patch, and then you must put the anti-peeping patch back on. [0005] 3. Brightness attenuation: Only in the position directly in f...

AI Technical Summary

Problems solved by technology

[0003] 1. Not completely anti-peep: the anti-peep patch provides a viewing angle of about 60 degrees, so other people within the viewing angle can still see the content on the screen

[0004] 2. Inconvenient to use: When you need to watch the screen with others, you need to remove the anti-peeping patch, and then you must put the anti-peeping patch back on

[0005] 3. Brightness attenuation: Only in the position directly in front of the completely vertical anti-peeping patch can you see the brightness close to the original, but as long as it deviates from the vertical direction, you will feel the brightness attenuation obviously

[0006] This shows that above-mentioned existing anti-peeping method of notebook computer and product obviously still have inconvenience and defect in method, product structure and use, and urgently need to be further improved

In order to solve the above-mentioned existing problems, relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable method and structure for general methods and products to solve the above-mentioned problems. This is obviously a problem that relevant industry players are eager to solve
