Description

Peep-proof module, processing method, display screen and electronic equipment

Technical Field

The embodiment of the application relates to the technical field of display, in particular to a peep-proof module, a processing method, a display screen and electronic equipment.

Background

When people use display-type electronic devices, such as mobile phones, peeping is sometimes encountered as shown in fig. 1 (a). For this reason, a privacy film having a privacy function has been developed, see fig. 1 (b). However, the peep-proof film has poor transmittance, reduces the definition of the display screen, and has obvious granular feel. Particularly, when the peep-proof film is applied to a folding screen mobile phone, the peep-proof film is extremely easy to crease and even break. In addition, the peep-proof film for the mobile phone display screen cannot realize switching between a peep-proof state and a sharing state, wherein the peep-proof state is that other people cannot share the content displayed on the display screen, and the sharing state is that other people can share the content displayed on the display screen.

The polymer dispersed liquid crystal (Polymer Dispersed Liquid Crystal, PDLC) applied to personal computer (Personal Computer, PC) products can realize switching between a peep-proof state and a sharing state, as shown in fig. 2, in which the PC display screen is in the peep-proof state in fig. 2 (a), and in which the PC display screen is in the sharing state in fig. 2 (b). Typically the PC display screen is a liquid crystal display (Liquid Crystal Display, LCD). However, even if a PDLC is inserted into an OLED, the organic light emitting display (Organic Light Emitting Display, OLED) using the mobile phone screen cannot switch between the peep-proof state and the sharing state.

Therefore, how to expand the application range of the peep-proof module is a technical problem to be solved by those skilled in the art.

Detailed Description

In order to enable those skilled in the art to more clearly understand the solution of the embodiment of the present application, the application scenario of the technical solution of the embodiment of the present application is first described below.

The polymer dispersed liquid crystal (Polymer Dispersed Liquid Crystal, PDLC) applied to personal computer (Personal Computer, PC) products can realize switching between a peep-proof state and a sharing state, as shown in fig. 2, in which the PC display screen is in the peep-proof state in fig. 2 (a), and in which the PC display screen is in the sharing state in fig. 2 (b). Typically the PC display screen is a liquid crystal display (Liquid Crystal Display, LCD).

Referring to fig. 3, fig. 3 shows a schematic structure of a PC display screen when it is an LCD. In the illustration, the PDLC2 is disposed below a liquid crystal panel (Opencell) 2 in the LCD and above a Backlight (BLU), and the PDLC2 realizes switching between the peep-proof state and the sharing state by controlling the Light emitting of the BLU 3. However, since the organic light emitting display (Organic Light Emitting Display, OLED) using the mobile phone screen does not have the BLU3 disposed therein, the switching between the peep-proof state and the sharing state cannot be realized even if the PDLC is inserted into the OLED.

In order to solve the technical problems, the embodiment of the application provides a peep-proof module, a processing method, a display screen and electronic equipment, and the application range of the peep-proof module can be improved. Further, the scheme of the embodiment of the application can be applied to various display screens. In addition, the peep-proof module provided by the embodiment of the application is compact and simple. The words "first," "second," and the like in the description of the embodiments herein are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. In the embodiment of the present application, terms of the directions such as "up", "down", "left" and "right" refer to the state of the peep-proof module in the drawings, and when the manner of arranging the peep-proof module 200 is different from that of the drawings, the directions in the following description of the embodiments of the present application should be adjusted.

A plurality of electrochromic devices (Electrochromic Device, abbreviated as ECD) are embedded in the peep-proof module, the ECD is composed of electrochromic materials, wherein the electrochromic materials (electrochromic materials, abbreviated as EC) refer to the phenomenon that the optical properties (reflectivity, transmissivity, absorptivity and the like) of the materials change stably and reversibly under the action of an applied voltage, and the appearance of the electrochromic materials shows reversible changes of color and transparency. Materials with electrochromic properties are referred to as electrochromic materials. Electrochromic materials are classified into inorganic electrochromic materials and organic electrochromic materials. A typical representative of electrochromic materials is tungsten trioxide, as described in WO ₃ Electrochromic devices, which are functional materials, have been industrialized. The organic electrochromic material mainly comprises polythiophene and derivatives thereof, viologen, tetrathiafulvalene, metal phthalocyanine compounds and the like. Electrochromic materials using viologen as a functional material have been practically used. When the ECD is subjected to a first preset voltage, the molar absorptivity changes due to the redox reaction of the EC. The EC changes its color from a transparent state to black or other colors in the visible light, and the ECD is in a non-transparent state, wherein the transmittance ranges from 1% to 99%, and the transmittance (transmissittance) is the ratio of the radiant energy projected through the object to the total radiant energy projected onto the object during the process of leaving the incident light flux from the illuminated surface or the medium incident surface to the other surface. When the ECD is subjected to a second preset voltage, the ECD is in a transparent state.

It should be noted that, the range of the first preset voltage is: 1.0V-2.0V direct current, the second preset voltage takes on the value range: -1.5V-0.6V dc.

In order to make the person skilled in the art more clearly understand the embodiments of the present application, the following describes the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application.

In the peep-proof module 200 in the embodiment of the present application, when a first preset voltage is loaded through the transparent electrode layer 220, the plurality of ECDs are in a non-transparent state, as shown in fig. 5 (a); when a second preset voltage is applied through the transparent electrode layer 220, the plurality of ECDs are in a transparent state, as shown in fig. 5 (b).

When the transparent electrode layer 220 is disposed under the electrochromic layer 210 in the height direction z, the transparent electrode layer 220 provides voltage support under the electrochromic layer 210, and the plurality of electrochromic devices 211 sequentially realize reversible color change from bottom to top.

The peep-proof module 200 in the description of the embodiment of the present application only takes a display screen applied to a rectangular structure as an example, and is applicable to a rectangular display screen, and the peep-proof module 200 in the description of the embodiment of the present application is of a rectangular structure, and has a height, a length and a width, wherein a direction corresponding to the height is a height direction z, a direction corresponding to the length is a length direction x, a direction corresponding to the width is a width direction y, and the height direction z, the length direction x and the width direction y are perpendicular to each other. Of course, the peep-proof module 200 may also be applicable to a display screen with a circular structure, and at this time, the peep-proof module 200 is of a cylindrical structure, and still has a height, and its length and width may be specified according to the orientation of the display screen, which is not specifically described in the examples of the embodiments of the present application.

As described above, when electrochromic device 211 is in the non-transparent state, the color is black or other visible light color, preferably blue, black or brown. Wherein blue, black or brown is a conventionally used color, and the electrochromic device 211 is conveniently formulated. The transmittance and the color of the electrochromic device 211 can be selected according to the specific requirements of the display screen, and the color and/or the transmittance displayed by the electrochromic device 211 can be correspondingly adjusted by adjusting the component proportion of the electrochromic device 211.

The transparent electrode layer 220 is used to load the electrochromic device 211 with a first preset voltage and a second preset voltage, and may be a transparent electrode such as ITO (indium tin oxide), a nano silver wire, etc., so long as the loading voltage can be realized, which is within the protection scope of the embodiments of the present application.
