[0070] In order to make the purpose, technical solution and advantages of the embodiment of the present disclosure clearer, the technical solution of the embodiment of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiment of the present disclosure. It should be noted that the size and shape of each figure in the drawings do not reflect the actual proportion, and the purpose is only to illustrate the content of the present disclosure. And the same or similar reference numerals throughout represent the same or similar elements or elements with the same or similar functions.

[0071] Unless otherwise defined, the technical or scientific terms used herein shall have the usual meanings understood by persons of ordinary skill in the field to which the present disclosure belongs. The words "first", "second" and similar terms used in the present disclosure specification and claims do not indicate any order, quantity or importance, but are only used to distinguish different components. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Inside", "outside", "upper", "lower" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0072] In the related art, the anti-peeping state is mainly achieved by attaching an anti-peeping film on the LCD screen. However, because the light output angle of the anti-peeping film cannot be adjusted, this solution is only applicable to the anti-peeping state and cannot achieve the switching between the anti-peeping state and the sharing state, resulting in a single application scenario and a poor user experience.

[0073] In order to solve the above technical problems existing in the related art, the present disclosure provides a dimming panel, such as Figure 1 and Figure 2 As shown, the dimming panel has a dimming area AA, including:

[0074] The first substrate 101 and the second substrate 102 are arranged opposite to each other; the materials of the first substrate 101 and the second substrate 102 can be glass, organic polymer or other transparent materials;

[0075] The first electrode 103 and the second electrode 104 are insulated from each other and are located between the first substrate 101 and the second substrate 102. The first electrode 103 and the second electrode 104 are located in the dimming area AA. At least one of the first electrode 103 and the second electrode 104 includes a plurality of strip electrodes (for example, the first strip electrode 1031 and / or the second strip electrode 1041). The extension trends of the strip electrodes are substantially the same (that is, exactly the same or within the error range caused by factors such as manufacturing and measurement). The orthographic projections of the strip electrodes on the first substrate 101 do not overlap each other.

[0076] The liquid crystal layer 105 is located between the first base substrate 101 and the second base substrate 102. The liquid crystal layer 105 is located in the dimming area AA. The liquid crystal layer 105 is arranged in a different layer from the layer where the first electrode 103 and the layer where the second electrode 104 are located. The liquid crystal layer 105 is configured to scatter the incident light under the control of the electric field formed between the first electrode 103 and the second electrode 104. For anti-peeping display, when the backlight is a collimated backlight, the anti-peeping effect is better, so it can be selected that the dimming panel in this case adjusts the incident collimated backlight.

[0077] In the dimming panel provided in the embodiment of the present disclosure, at least one of the first electrode 103 and the second electrode 104 is provided to include a plurality of strip electrodes with substantially the same extension trend, so that after applying voltage to the first electrode 103 and the second electrode 104, the electric field lines formed between the first electrode 103 and the second electrode 104 will be directed from the positive electrode (e.g., the first electrode 103) to the negative electrode (e.g., the second electrode 104) along the extension direction of the strip electrodes, and the liquid crystal molecules are deflected under the action of the electric field, and when the collimated light is irradiated on the liquid crystal layer 105, it will be scattered, and it is in a shared state at this time; and when no voltage is applied to the first electrode 103 and the second electrode 104, the refractive index of the liquid crystal layer 105 at different positions in the vertical direction Z of the first substrate 101 is consistent, and when the collimated light passes through the liquid crystal layer 105, its direction is basically unchanged, and it is still collimated light, and the anti-peeping state can be achieved at this time. Thus, the switching between the anti-peeping state and the sharing state is achieved, and the user experience is enhanced.

[0078] In some embodiments, the dimming panel provided by the present disclosure can realize one-key switching of anti-peeping state. For example, a user can send a viewing angle switching request to the dimming panel through a physical button, software or application (APP), and the flexible circuit board controls the voltage signal applied to the first electrode 103 and the second electrode 104 to realize the switching between the shared state and the anti-peeping state.

[0079] Figure 1 and Figure 2 The dimming panel provided by the embodiment of the present disclosure is shown as follows. Figure 1 and Figure 2 It can be seen that the first electrode 103 is located on the side of the first base substrate 101 facing the second base substrate 102, and the second electrode 104 is arranged in the same layer as the first electrode 103; the first electrode 103 includes a plurality of first strip electrodes 1031, and the second electrode 104 includes a plurality of second strip electrodes 1041, the second strip electrodes 1041 and the first strip electrodes 1031 are alternately arranged, and the first strip electrodes 1031 and the second strip electrodes 1041 are bent and extended.

[0080] See also Figure 3 and Figure 4, after voltage is applied to the bent and extended first strip electrode 1031 and the second strip electrode 1041, the electric field lines formed between the first strip electrode 1031 and the second strip electrode 1041 will be directed from the positive electrode (e.g., the first strip electrode 1031) to the negative electrode (e.g., the second strip electrode 1041) along the bending direction thereof, and the liquid crystal molecules are deflected under the action of the electric field, resulting in changes in the refractive index of the liquid crystal layer 105 at different positions in the vertical direction Z of the first substrate 101, and when collimated light is irradiated on the liquid crystal layer 105, scattering will occur, and at this time, it is in a shared state; and as Figure 5 and Figure 6 As shown, when no voltage is applied to the first strip electrode 1031 and the second strip electrode 1041, the refractive index of the liquid crystal layer 105 at different positions in the vertical direction Z of the first substrate 101 is consistent. When the collimated light passes through the liquid crystal layer 105, its direction is basically unchanged and it is still collimated light. At this time, a full-viewing angle (including up, down, left, and right) anti-peeping state can be achieved. The electrode structure in this case refers to Figure 1 , designed to bend and extend similar to an S shape or a fold line shape, then the electric field formed between the first strip electrode 1031 and the second strip electrode 1041 to drive the liquid crystal to rotate can be in multiple directions. Compared with the electrode setting extending in a straight line, the electric field can only be extended along a single direction of the vertical electrode to achieve an anti-peeping effect in one direction. In addition, this case can disperse the backlight in multiple directions to achieve full-view anti-peeping, that is, to achieve full-view anti-peeping with light contraction in all directions. And because this case can disperse the backlight in multiple directions, the sharing state is also greatly improved. In addition, by applying voltage to the first strip electrode 1031 and the second strip electrode 1041 so that different voltage differences are formed between the two (for example, the voltage difference is 1V to 25V), the deflection degree of the liquid crystal molecules can be controlled to be different, thereby controlling the divergence degree of the liquid crystal layer to the collimated light to be different, achieving different sharing effects, and realizing the switching between the full-view anti-peeping state and multiple sharing states, which significantly enhances the user experience. It should be noted that, referring to Figure 3 , the first strip electrode 1031 and the second strip electrode 1041 are designed in the same layer. Of course, it is optional that the first strip electrode 1031 and the second strip electrode 1041 are designed in different layers, for example, both are arranged on the first base substrate 101 side, and the two different layers are insulated from each other. Of course, one of the two can also be arranged on the second base substrate 102, and the other electrode is arranged on the first base substrate 101, and the first strip electrode 1031 and the second strip electrode 1041 do not overlap each other in a direction perpendicular to the first base substrate 101. These optional structures can be arranged according to the actual process and are not limited here.

[0081] It should be noted that in the present disclosure, "same layer" refers to a layer structure formed by using the same film-forming process to form a film layer for making a specific pattern, and then using the same mask to form a layer structure through a single patterning process. That is, one patterning process corresponds to a mask (also called a photomask). Depending on the specific pattern, one patterning process may include multiple exposure, development or etching processes, and the specific patterns in the formed layer structure may be continuous or discontinuous, and these specific patterns may be at the same height or have the same thickness, or at different heights or have different thicknesses.

[0082] In some embodiments, Figure 1 As shown, to obtain a better sharing state effect, the shape of the first strip electrode 1031 and the shape of the second strip electrode 1041 can be substantially the same (ie, exactly the same or within the error range caused by factors such as manufacturing and measurement). Moreover, the line width w1 of the first strip electrode 1031 and the line width w2 of the second strip electrode 1041 may be equal or unequal. The line width w1 of the first strip electrode 1031 and the line width w2 of the second strip electrode 1041 may be between 1.0 μm and 15 μm respectively, and the line spacing d of the first strip electrode 1031 and the second strip electrode 1041 at different positions may be between 2.0 μm and 15 μm. For example, the line width w1 of the first strip electrode 1031 and the line width w2 of the second strip electrode 1041 may both be 1 μm, 5 μm, 10 μm, 15 μm, etc., and the line spacing d of the first strip electrode 1031 and the second strip electrode 1041 at different positions may be 2 μm, 5 μm, 10 μm, 15 μm, etc.

[0083] Optionally, the present disclosure also provides effect diagrams of the anti-peeping state and the sharing state under different line widths and line distances, such as Figures 7 to 13 Specifically, Figure 7 This is the anti-peeping effect diagram under different line widths and line distances. Figures 8 to 13 The corresponding shared state effect diagrams are 3:3, 3:4, 3:5, 3:6, 3:8, and 3:20 for the line width / line spacing ratios, for example Figures 8 to 13 The line width is 3μm, and the line spacing is 3μm, 4μm, 5μm, 6μm, 8μm, and 20μm respectively. Figure 7 It can be seen that in the anti-peeping state, the collimated light emitted by the collimated light source still maintains a good collimation effect after passing through the dimming panel; Figures 8 to 12 It can be seen that when the line width / line spacing ratio decreases from 3:3 to 3:4, 3:5, 3:6, and 3:8, the light divergence is higher and the sharing effect is better. Fig.13It can be seen that when the line width / line spacing ratio is 3:20, the light divergence becomes weaker and the shared state effect is acceptable. Therefore, in the present disclosure, the line width and line spacing of the first strip electrode 1031 and the second strip electrode 302 cannot be infinitely increased. When the line width increases, the driving force for driving the liquid crystal to rotate and disperse the light will be weakened, and the Figures 8 to 13 It can be seen that too large a line distance will weaken the sharing effect, so the ratio of the line width and the line distance of the first strip electrode 1031 and the second strip electrode 302 at any position in their extending direction must be selected between (3 / 20) and (3 / 3).

[0084] In some embodiments, in order to apply voltage to the first strip electrode 1031 and the second strip electrode 1041, as shown in FIG. Fig.14 As shown, the first lead 106 and the second lead 107 may be disposed in the peripheral area BB surrounding the dimming area AA, and the first lead 106 is electrically connected to the first strip electrode 1031 , and the second lead 107 is electrically connected to the second strip electrode 1041 .

[0085] Optionally, the first lead 106 and the second lead 107 can be arranged in the same layer as the first strip electrode 1031 and the second strip electrode 1041. For example, the first lead 106 and the first strip electrode 1031 are integrally arranged, and the second lead 107 and the second strip electrode 1041 are integrally arranged. The first lead 106 and the second lead 107 can be designed in the same layer and the same material as the first strip electrode 1031 and the second strip electrode 1041, for example, both are ITO. In order to reduce the resistance, The first lead 106 and the second lead 107 are designed with metal materials, and the first strip electrode 1031 and the second strip electrode 1041 are made of ITO materials. At this time, the first strip electrode 1031 and the second strip electrode 1041 are designed on the same layer, and the first lead 106 and the second lead 107 are designed on the same layer. At this time, the first lead 106 and the first strip electrode 1031 are electrically connected through vias, and the second lead 107 and the second strip electrode 1041 are electrically connected through vias, which are not limited here. When the first lead 106 and the second lead 107 can be arranged in the same layer as the first strip electrode 1031 and the second strip electrode 1041, in order to avoid the short circuit between the first lead 106 and the second strip electrode 1041, and at the same time avoid the short circuit between the second lead 107 and the first strip electrode 1031, the first lead 106 needs to be electrically connected to one end of the first strip electrode 1031 adjacent to the first peripheral area BB1, and the second lead 107 needs to be electrically connected to one end of the second strip electrode 1041 away from the first peripheral area BB1, wherein the first peripheral area BB1 is used to bind a circuit board (such as a flexible circuit board FPC), and is located on one side of the alternating arrangement direction of the first strip electrodes 1031 and the second strip electrodes 1041.

[0086] In some embodiments, Figures 15 to 17As shown, the first lead 106 and the second lead 107 can also be arranged in the same layer between the layer where the first strip electrode 1031 is located and the first base substrate 101. Optionally, in order to maintain the consistency of the signal size from one end of the first strip electrode 1031 adjacent to the first peripheral area BB1 to the other end thereof away from the first peripheral area BB1, the first lead 106 can be arranged to be electrically connected to both ends of the first strip electrode 1031. For similar reasons, the second lead 107 can be arranged to be electrically connected to both ends of the second strip electrode 1041. In addition, in order to avoid short-circuiting the first lead 106 and the second strip electrode 1041, the second lead 107 is short-circuited with the first strip electrode 1031, as shown in FIG.

It can be seen that Fig.24 and Fig.25 The structure of the first electrode 103 and the second electrode 104 is Figure 1 and Figure 2 The structures of the first electrode 103 and the second electrode 104 are the same, and the difference is only in the position of the film layer. Therefore, Fig.24 and Fig.25 The principle of switching between full-view anti-peeping state and shared state can be referred to Figure 1 and Figure 2 The relevant contents in the article will not be elaborated here.

[0093] in addition, Fig.24 and Fig.25 The dimming panel shown also has a liquid crystal layer 105, a first lead 106, a second lead 107, a first resistance reduction line 109, a second resistance reduction line 110, a first terminal 111, a second terminal 112, a first alignment layer 113 and a second alignment layer 114. Figure 1 , Fig.14 , Fig.15 and Fig.18 The differences between the corresponding components are explained in detail, and the repeated parts are not repeated here.

[0094] Specifically, Figure 24 to Figure 27 As shown, the first lead 106 and the second lead 107 are arranged in the same layer between the first base substrate 101 and the layer where the second strip electrode 1041 is located, and there is a second insulating layer 115 located between the layer where the first strip electrode 1031 is located and the layer where the second strip electrode 1041 is located in the dimming area AA and the peripheral area BB, the second insulating layer 115 has a third via h3 in the peripheral area BB, the orthographic projection of the third via h3 on the first base substrate 101 is located within the orthographic projection of the first lead 106 on the first base substrate 101, the first lead 106 is electrically connected to the first strip electrode 1031 through the third via h3 penetrating the second insulating layer 115, and the second lead 107 can be in contact with and electrically connected to the second strip electrode 1041.

In addition, the first terminal 111 can also be arranged at the same layer as the first strip electrode 1031 and the second strip electrode 1041, so that the first terminal 111 has a laminated structure, and similarly, the second terminal 112 can also be arranged at the same layer as the first strip electrode 1031 and the second strip electrode 1041, so that the second terminal 112 has a laminated structure.

[0096] Figure 30 to Figure 32 The dimming panel provided by the embodiment of the present disclosure is shown. In the dimming panel, the first electrode 103 is located on the side of the first base substrate 101 facing the second base substrate 102, and the second electrode 104 is located between the layer where the first electrode 103 is located and the first base substrate 101; the first electrode 103 includes a plurality of curved and extended first strip electrodes 1031, and the second electrode 104 is a planar electrode 1042.

[0097] against Figure 30 to Figure 32 In the dimming panel shown, after voltage is applied to the planar electrode 1042 and the curved and extended first strip electrode 1031, the electric field lines formed between the first strip electrode 1031 and the planar electrode 1042 will be directed from the positive electrode (e.g., the first strip electrode 1031) to the negative electrode (e.g., the planar electrode 1042) along the bending direction and the opposite direction of the two, and the liquid crystal molecules are deflected under the action of the electric field, resulting in changes in the refractive index of the liquid crystal layer 105 at different positions in the vertical direction Z of the first base substrate 101. When collimated light is irradiated on the liquid crystal layer 105, scattering occurs, and it is in a shared state at this time; and when no voltage is applied to the first strip electrode 1031 and the planar electrode 1042, the refractive index of the liquid crystal layer 105 at different positions in the vertical direction Z of the first base substrate 101 is consistent, and when the collimated light passes through the liquid crystal layer 105, its direction does not change substantially, and it is still collimated light, and a full-viewing angle (including up, down, left, and right) anti-peeping state can be achieved at this time. In addition, by applying voltage to the first strip electrode 1031 and the planar electrode 1042 to form different voltage differences therebetween (for example, a voltage difference of 1V to 25V), the deflection degree of the liquid crystal molecules can be controlled to be different, thereby controlling the divergence degree of the liquid crystal layer to the collimated light to be different, achieving different sharing effects, and realizing the switching between the full-view anti-peeping state and multiple sharing states, which significantly enhances the user experience.
