Description

TECHNICAL FIELD

[0001] The utility model relates to electronic display equipment technical field especially, relates to a kind of fingerprint unlocking anti-peeping film and electronic display equipment. BACKGROUND

[0002] Fingerprint unlocking anti-peeping film is a screen protection film that has both anti-peeping function and can support fingerprint unlocking. Anti-peeping film adopts ultra-fine louver optical patent technology, and the structure of louver is reduced by several ten thousand times and arranged in the film. When looking from the front, light can normally pass through, and the screen content can be clearly seen. When looking from the side, light is blocked by the louver structure, and only a black picture can be seen, thereby achieving the effect of anti-peeping. For the optical screen-under-fingerprint identification technology mobile phone, the sensor under the screen will emit light to illuminate the fingerprint of the finger, then collect the light reflected back by the fingerprint, and unlock by comparing the recorded fingerprint information. Therefore, the louver structure of the anti-peeping film easily affects the unlocking of the fingerprint.

[0003] In the prior art, the first solution is to make the depth of the grid anti-peeping structure shallow to realize fingerprint unlocking of the anti-peeping film. However, after making the structure depth shallow, the anti-peeping angle is greatly lost, and the fingerprint unlocking is not sensitive. The second solution is to remove the fingerprint unlocking position of the anti-peeping film by punching and then paste it on the screen. First, it is not beautiful, and second, the punched position is concave and not easy to clean, which affects the unlocking sensitivity after long-term use. Therefore, it is necessary to design a fingerprint unlocking anti-peeping film that can improve the sensitivity of fingerprint unlocking without losing the anti-peeping angle, and also avoid the problem that the punched position is concave and not easy to clean, which affects the unlocking sensitivity after long-term use.
