Embodiment approach

[0057] Specifically, the first implementation, such as figure 1 and image 3 As shown, the electrophoretic layer 3 may specifically include: a transparent dispersion medium 32, and a plurality of colorant particles dispersed in the transparent dispersion medium 32, the colorant particles may specifically be black pigment / dye particles, and at this time, the black pigment / dye particles The charged particles 31 are used to absorb light. Since the black pigment / dye particles are opposite to the electric properties of the first sub-electrode 41, the black pigment / dye particles will be adsorbed to the position of the first sub-electrode 41 under the action of an electric field, forming a side Viewing angle line of sight barrier, thereby realizing anti-peeping function.

[0058] Specifically, the second embodiment, such as figure 2 As shown, in the above-mentioned anti-peeping device provided by the embodiment of the present invention, the electrophoretic layer 3 may specifically...

Abstract

The invention discloses an anti-peep device, an anti-peep method thereof, and a display device; the anti-peep device comprises an upper substrate and a lower substrate arranged oppositely, well as an electrophoretic layer filling spacing between the substrate and the lower substrate; one side of the upper substrate and/or the lower substrate facing the electrophoretic layer is provided with an electrode layer; the electrode layer includes a plurality of first sub-electrodes distributed in the first direction; the electrophoretic layer includes charged particles opposite to the first sub-electrodes in electrical property and used for absorbing light. The anti-peep device provided by the embodiment of the invention controls a gathering position of the charged particles for absorbing light through the first sub-electrodes, forming a side view barrier to achieve anti-peep functionality; the anti-peep method is simple, the raw materials are cheap, the anti-peep effect is significant, the view angle is controllable, and personal privacy is protected perfectly.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an anti-peeping device, its anti-peeping method and a display device. Background technique [0002] Viewing angle is a key indicator of a display, and different applications have different requirements for viewing angles. When the user is in an open environment that requires confidentiality, such as entering a withdrawal password, viewing private information or business negotiations on public transportation, the display needs to have a narrower viewing angle to protect personal privacy. At this time, anti-peeping devices with controllable viewing angles become a necessity. [0003] The anti-spying technology widely used at present is the anti-spying film of 3M Company in the United States. Its structure is realized by the vertical arrangement of ultra-microstructures, and each ultra-micro-structure is at a vertical angle to the display. There are few products on the market tha...
