Problems solved by technology

However, it can be seen from the actual implementation that the disadvantage of this solution is that the anti-peeping state has too high lateral transmittance and poor forward transmittance, and the conversion between wide and narrow viewing angles is very slow. The performance and driving stability of the display deteriorate sharply when switching between wide and narrow viewing angles

Embodiment Construction

[0023] Such as Figure 3 to Figure 8 As shown, the peep-proof display 10 of the present invention includes a liquid crystal display panel 11, and the liquid crystal display panel 11 can adopt various liquid crystal display panels existing on the market for displaying images. (not shown in ) to adjust most of the light emitted by the collimated light into the collimated light realization module 30, between the liquid crystal display panel 11 and the collimated light realization module 30, there is a The anti-peeping display 10 of the present invention can be switched between the anti-peeping state with a narrow viewing angle and the non-peeping-proof state with a wide viewing angle, and the anti-peeping display of the anti-peeping display 10 of the present invention can be adjusted through different translucent grayscale progressive states. The light-adjusting film 12 with strong and weak effects, in other words, the liquid crystal display panel 11, the light-adjusting film 12,...

Abstract

The invention discloses a glance proof display. The glance proof display comprises a liquid crystal display panel. The back side of the liquid crystal display panel is provided with a collimating light realization module, wherein the collimating light realization module adjusts most ray of light sent from a backlight to collimating light and then shots; a function and a dimmer film are arranged between the liquid crystal display panel and the collimating light realization module, wherein the function is capable of switching between narrow visual angle glance proof state and broad visual angle glance state through switching between transparent state and milled state, and the dimmer film adjusts effect strength of glance proof through different translucent gray scale progressive state. The glance proof display is capable of realizing fast switch between narrow visual angle glance proof state and broad visual angle glance state and has good glance proof effect.

Description

technical field [0001] The invention relates to an anti-peeping display capable of fast switching between a non-peep-proof state with a wide viewing angle and a peep-proof state with a narrow viewing angle, and belongs to the technical field of peep-proof display. Background technique [0002] Most of the anti-peeping displays currently on the market rely on the anti-peeping film to achieve the anti-peeping effect. No matter whether the anti-spy film is placed outside the anti-spy display or built into the anti-spy display, it can only keep the anti-spy display in the state of the anti-spy state, and cannot realize the anti-spy state and the non-spy state. The switching between the two states of the peep state, that is, there is no switching between the narrow viewing angle and the wide viewing angle. However, if you want to switch to a wide viewing angle, you need to remove the privacy film from the privacy display, which is very inconvenient to use. figure 1 Shown is a s...
