[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0045] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0046] Figure 1 This is a schematic diagram of the structure of a display device provided in an embodiment of the present utility model, as shown below. Figure 1As shown, the display device includes a display panel 110, an image acquisition module 120, and a control module 130;

[0047] The image acquisition module 120 is located in the border area of ​​the display surface of the display panel 110. The image acquisition module 120 is connected to the control module 130, and the control module 130 is connected to the display panel 110. The image acquisition module 120 is used to acquire image information around the display panel 110. The control module 130 is used to control the display panel 110 to adjust the width and narrowness of different display areas and the display position of the privacy software according to the image information in the dynamic viewing angle adjustment mode.

[0048] The display panel 110 includes multiple display zones, each capable of displaying an image independently. The dynamic viewing angle adjustment mode refers to a control mode that automatically adjusts the display screen (switching the privacy software position) and viewing angle of each display zone based on the surrounding environment of the display panel 110. Therefore, in dynamic viewing angle adjustment mode, the control module 130 can process image information, analyze the surrounding environment of the display panel 110, confirm information such as the positions of people around the user, and dynamically adjust the viewing angles of different display zones of the display panel 110 and the display position of the privacy software based on these positions. The privacy software is pre-set by the user.

[0049] Based on the above connection relationship, the working process of the display device is described as follows: The image acquisition module 120 can acquire image information around the display panel 110 in real time and transmit the acquired image information to the control module 130. After receiving the image information, the control module 130 processes the image information, analyzes the environment around the display panel 110, confirms the position of people around the user of the display panel 110, and, based on the position of people around the user of the display panel 110, shrinks the pre-set privacy software of the display to a position where the view of people around the user of the display panel 110 is obstructed, and adjusts the display viewing angle of the position where the view of people around the user of the display panel 110 is obstructed to a narrow viewing angle.

[0050] For example, Figures 2-6 Image information acquired by an image acquisition module provided in this embodiment of the utility model, if the image information acquired by the image acquisition module 120 is as follows: Figure 2 As shown, after processing and analysis by the control module 130, if it is confirmed that there is no one around the user on the display panel 110, the control module 130 will automatically adjust the viewing angle of the display panel 110 to a wide viewing angle; if the image information acquired by the image acquisition module 120 is as follows... Figure 3As shown, after processing and analysis by the control module 130, if it is confirmed that the people around the user on the display panel 110 are located on the right side of the display panel 110, the control module 130 will adjust the viewing angle of the left display area of ​​the display panel 110 to a narrow viewing angle and shrink the pre-set privacy software to the left display area; if the image information acquired by the image acquisition module 120 is as follows... Figure 4 As shown, after processing and analysis by the control module 130, if it is confirmed that the people around the user on the display panel 110 are located on the left side of the display panel 110, the control module 130 will adjust the viewing angle of the right display area of ​​the display panel 110 to a narrow viewing angle and shrink the pre-set privacy software to the right display area; if the image information acquired by the image acquisition module 120 is as follows... Figure 5 As shown, after processing and analysis by the control module 130, if it is confirmed that the people around the user of the display panel 110 are located on the left and right sides of the display panel 110, the control module 130 will adjust the viewing angle of all display areas of the display panel 110 to a narrow viewing angle; if the image information acquired by the image acquisition module 120 is as shown... Figure 6 As shown, after processing and analysis by the control module 130, if it is confirmed that there are people around the user on the display panel 110, the control module 130 will adjust the viewing angle of all display areas of the display panel 110 to a narrow viewing angle and shrink the pre-set privacy software to the display area near the center of the display panel 110.

[0051] In this embodiment of the utility model, the image acquisition module 120 acquires image information around the display panel 110, and the control module 130 controls the display panel 110 to automatically adjust the width and narrowness of different display areas and the display position of the privacy software according to the image information in the dynamic viewing angle adjustment mode, so as to protect the user's privacy in a timely manner.

[0052] Based on the above embodiments, optionally, Figure 7 This is a schematic diagram of the structure of a display panel provided in an embodiment of the present utility model. Figure 7 As shown, the display panel 110 includes: a backlight 111; a privacy layer 112, which is disposed on the light source side of the backlight 111 to converge the light emitted by the backlight 111 and control the light to be emitted perpendicularly to the privacy layer 112; a prism dimming module 113, which is disposed on the side of the privacy layer 112 away from the backlight 111; the prism dimming module 113 is connected to a control module 130, which is used to control the prism dimming module 113 to adjust the emission path of the incident light according to the image information in the dynamic viewing angle adjustment mode, so as to change the width and narrow viewing angle of different display areas.

[0053] The backlight 111 is the light-emitting part of the display panel 110, providing light to the display panel 110. The privacy layer 112 can control the direction of the light emitted from the screen, converge the light emitted from the backlight 111, and control the light to be emitted perpendicularly to the privacy layer 112, so that the light emitted from the backlight 111 is more accurately guided to the front of the screen, improving the light utilization efficiency and reducing the scattering of light to the sides. The prism dimming module 113 is an optical component that can adjust the light. It controls the light through the refraction and reflection of prisms and the principle of electromagnetic field modulation of liquid crystals, so as to adjust the exit path of the incident light and thus change the viewing angle of different display areas.

[0054] Based on the above embodiments, optionally, Figure 8 This is a schematic diagram of the structure of a physical prism dimming box provided in an embodiment of this utility model. Figure 8 As shown, the prism dimming module 113 includes a physical prism dimming box;

[0055] The physical prism dimming box includes a first substrate 1131, a first transparent conductive layer 1132, a first liquid crystal molecule layer 1133, a prism layer 1134, a second transparent conductive layer 1135, and a second substrate 1136.

[0056] The second substrate 1136, the second transparent conductive layer 1135, the prism layer 1134, the first liquid crystal molecule layer 1133, the first transparent conductive layer 1132 and the first substrate 1131 are sequentially stacked on the side of the privacy layer 112 away from the backlight 111.

[0057] Both the first transparent conductive layer 1132 and the second transparent conductive layer 1135 are connected to the control module 130;

[0058] The refractive index of light propagating along the direction perpendicular to the long axis of the first liquid crystal molecules in the first liquid crystal molecule layer 1133 is equal to the refractive index of the prism layer 1134, and the refractive index of light propagating along the direction perpendicular to the long axis of the first liquid crystal molecules in the first liquid crystal molecule layer 1133 is greater than the refractive index of the prism layer 1134.

[0059] The first liquid crystal molecule layer 1133 has a certain polarity. Under the influence of an electric or magnetic field, the orientation of the first liquid crystal molecules changes, thereby causing a change in refractive index, i.e., the refractive index is different along different directions. The control module 130 changes the voltage between the first transparent conductive layer 1132 and the second transparent conductive layer 1135, thereby changing the electric field between the first transparent conductive layer 1132 and the second transparent conductive layer 1135, and thus changing the polarity of the first liquid crystal molecule layer 1133.

[0060] For example, when the voltage applied to both the first transparent conductive layer 1132 and the second transparent conductive layer 1135 is 0V, light propagates along the long axis of the first liquid crystal molecule, and the refractive index of the light propagating along the long axis of the first liquid crystal molecule is n. e When the voltage applied to the first transparent conductive layer 1132 is 0V and the voltage applied to the second transparent conductive layer 1135 is ±10V, light propagates perpendicular to the long axis of the first liquid crystal molecule, and the refractive index of light propagating perpendicular to the long axis of the first liquid crystal molecule is n0.

[0061] Prism layer 1134 is a functional layer with a prism-shaped microstructure that can manipulate the path and distribution of light by utilizing the principles of light refraction and reflection.

[0062] The physical prism dimming box alters the refractive index of the first liquid crystal molecule layer 1133 through the first transparent conductive layer 1132 and the second transparent conductive layer 1135. When the refractive index of the first liquid crystal molecule layer 1133 is greater than that of the prism layer 1134, light passing through the prism layer 1134 and the first liquid crystal molecule layer 1133 in sequence allows the vertically emitted light to diffuse over a wider angle, thereby expanding the viewing angle and adjusting the viewing angle of the display area to a wide viewing angle, ensuring that viewers receive sufficient light from different viewing positions (e.g., ...). Figure 8 (Left half schematic diagram). When the refractive index of the first liquid crystal molecule layer 1133 is equal to the refractive index of the prism layer 1134, light passing through the prism layer 1134 and the first liquid crystal molecule layer 1133 in sequence will cause the light to exit perpendicularly, thereby focusing the light into a smaller angle range and adjusting the viewing angle of the display area to a narrow viewing angle (e.g., Figure 8 (Diagram of the right half).

[0063] Based on the above embodiments, alternatively, refer to the following: Figure 8 The second transparent conductive layer 1135 includes at least two transparent conductive blocks, adjacent transparent conductive blocks are not connected, and each transparent conductive block is connected to the control module 130.

[0064] The control module 130 applies different voltages to different transparent conductive blocks, which can control the different viewing angles of different display areas corresponding to different transparent conductive blocks.

[0065] For example, Figure 9 A control module provided for embodiments of this utility model Figure 8 Voltage signal diagrams of different transparent conductive blocks in the middle, such as Figure 9As shown, the voltage applied to the first transparent conductive layer 1132 is 0V, the voltage applied to the right transparent conductive block is ±10V, and the voltage applied to the left transparent conductive block is 0V. Therefore, the electromagnetic field between the right transparent conductive block and the first transparent conductive layer 1132 changes the refractive index of the first liquid crystal molecular layer 1133 to be equal to the refractive index of the prism layer 1134, causing the light to exit perpendicularly, thus focusing the light into a smaller angular range and adjusting the viewing angle of the display area to a narrow viewing angle. Conversely, the electromagnetic field between the left transparent conductive block and the first transparent conductive layer 1132 changes the refractive index of the first liquid crystal molecular layer 1133 to be greater than the refractive index of the prism layer 1134, allowing the perpendicularly emitted light to diffuse to a wider angle, thereby expanding the viewing angle and adjusting the viewing angle of the display area to a wide viewing angle.

[0066] Optionally, based on the above embodiments, Figure 10 This is a schematic diagram of the structure of a liquid crystal prism dimming box provided for an embodiment of this utility model. (See attached diagram.) Figure 10 As shown, the prism dimming module 113 includes a liquid crystal prism dimming box;

[0067] The liquid crystal prism dimming box includes a third substrate 1141, a second liquid crystal molecule layer 1142, an optical path control layer 1143, and a fourth substrate 1144.

[0068] The fourth substrate 1144, the optical path control layer 1143, the second liquid crystal molecule layer 1142 and the third substrate 1141 are stacked sequentially on the side of the privacy layer 112 away from the backlight 111, and the optical path control layer 1143 is connected to the control module 130.

[0069] The control module can change the electric field of the region where the second liquid crystal molecule is located by applying different voltages to the optical path control layer 1143, thereby changing the orientation of the second liquid crystal molecule. This allows the second liquid crystal molecule to refract the incident light, thereby adjusting the exit path of the incident light and changing the viewing angle of different display areas.

[0070] Based on the above embodiments, alternatively, refer to the following: Figure 10 The optical path control layer 1143 includes multiple optical path control areas; adjacent optical path control areas are not connected, and each optical path control area is connected to the control module 130.

[0071] Figure 10 In the middle, the optical path control layer 1143 includes two optical path control areas. The left half of the optical path control layer 1143 is an optical path controller (the optical path control layer 1143 with pink and blue electrodes), and the right half of the optical path control layer 1143 is another optical path controller (the optical path control layer 1143 with yellow and purple electrodes).

[0072] Specifically, the optical path control area includes a first transparent conductive gate layer 11431, an insulating layer 11432, and a second transparent conductive gate layer 11433;

[0073] The first transparent conductive gate layer 11431 includes a plurality of first conductive gate strips arranged in an array, and the edges of the first conductive gate strips are electrically connected.

[0074] An insulating layer 11432 is disposed between the first transparent conductive gate layer 11431 and the second transparent conductive gate layer 11433;

[0075] The second transparent conductive gate layer 11433 includes a plurality of second conductive gate strips arranged in an array, and the edges of the second conductive gate strips are electrically connected.

[0076] The first conductive grid and the second conductive grid are arranged in an alternating vertical projection on the fourth substrate 1144;

[0077] Both the first transparent conductive gate layer 11431 and the second transparent conductive gate layer 11433 are connected to the control module 130.

[0078] For example, Figure 11 This is a top view of a first transparent conductive gate layer and a second transparent conductive gate layer provided in an embodiment of the present invention. Figure 11 In this design, if the top view is the top view of the first transparent conductive gate layer 11431, then the bottom view is the top view of the second transparent conductive gate layer 11433. Similarly, if the top view is the top view of the second transparent conductive gate layer 11433, then the bottom view is the top view of the first transparent conductive gate layer 11431. This design does not impose specific limitations on this aspect.

[0079] according to Figure 11It is known that the vertical projections of the first conductive gate strip and the second conductive gate strip on the fourth substrate 1144 are staggered, meaning that the vertical projections of the first conductive gate strip and the second conductive gate strip on the fourth substrate 1144 do not intersect or overlap. Therefore, when the control module 130 applies different voltages to the first transparent conductive gate layer 11431 and the second transparent conductive layer 1135, an electric field is generated from the first transparent conductive gate layer 11431 toward the second transparent conductive layer 1135 or from the second transparent conductive gate layer 11433 toward the first transparent conductive layer 1132. Under the influence of the electric field, the second liquid crystal in the second liquid crystal layer deflects, reflecting the incident light and allowing the light to diffuse over a wider angle, thereby expanding the viewing angle and adjusting the viewing angle of the display area to a wide viewing angle, ensuring that viewers receive sufficient light from different viewing positions. When the control module 130 does not apply voltage to either the first transparent conductive gate layer 11431 or the second transparent conductive layer 1135, the position of the second liquid crystal layer is not affected by the electric field. The long axis of the second liquid crystal will rotate to a position where the long axis is perpendicular to the display surface, so that the light converged by the privacy layer 112 is emitted vertically, thereby focusing the light into a smaller angle range and adjusting the viewing angle of the display area to a narrow viewing angle.

[0080] Based on the above embodiments, alternatively, refer to the following: Figure 11 The liquid crystal prism dimming box also includes a third transparent conductive layer 1145;

[0081] The third transparent conductive layer is disposed between the third substrate 1141 and the second liquid crystal molecule layer 1142, and the third transparent conductive layer is connected to the control module 130.

[0082] When the control module 130 applies different voltages to the first transparent conductive gate layer 11431, the second transparent conductive layer 1135, and the third transparent conductive layer, the electric fields generated by the first transparent conductive gate layer 11431 and the second transparent conductive layer 1135, the electric fields generated by the first transparent conductive gate layer 11431 and the third transparent conductive layer, and the electric fields generated by the second transparent conductive gate layer 11433 and the third transparent conductive layer will be superimposed. This will cause the second liquid crystal in the second liquid crystal layer to deflect under the influence of the electric field, reflecting the incident light and allowing the light to diffuse to a wider angle, thereby expanding the viewing angle and adjusting the viewing angle of the display area to a wide viewing angle, so that the audience can receive enough light from different viewing positions.

[0083] Based on the above embodiments, exemplarily, Figure 12 A control module provided for embodiments of this utility model Figure 10 Voltage signal diagrams for the first, second, and third transparent conductive gate layers. (See diagram for example.) Figure 12As shown, the voltage applied to the left first transparent conductive gate layer ITO1-1, the left second transparent conductive gate layer ITO2-1, and the third transparent conductive layer ITO3 is 0V. The voltage applied to the right first transparent conductive gate layer ITO1-2 and the right second transparent conductive gate layer ITO2-2 is ±5V. Therefore, the position of the second liquid crystal layer between the left first transparent conductive gate layer ITO1-1 and the left second transparent conductive gate layer ITO2-1 is not affected by an electric field. The long axis of the second liquid crystal rotates to a position perpendicular to the display surface, causing the light converged by the privacy layer 112 to exit perpendicularly, thereby focusing the light into a smaller angle range and adjusting the viewing angle of the display area to a narrow viewing angle. The second liquid crystal between the first transparent conductive gate layer ITO1-2 and the second transparent conductive gate layer ITO2-2 on the right side is deflected under the influence of the superimposed electric field generated by the first transparent conductive gate layer ITO1-2, the second transparent conductive gate layer ITO2-2 and the third transparent conductive layer ITO3 on the right side. This reflects the incident light, allowing the light to diffuse to a wider angle, thereby expanding the viewing angle and adjusting the viewing angle of the display area to a wide viewing angle, so that viewers can receive sufficient light from different viewing positions.

[0084] Optionally, based on the above embodiments, the display device further includes a mode adjustment module;

[0085] The mode adjustment module is used to generate a mode switching signal. The control module 130 is used to adjust the view switching mode to the sharing mode according to the mode switching signal in the dynamic view adjustment mode, and to adjust the view switching mode to the dynamic view adjustment mode according to the mode switching signal in the sharing mode.

[0086] When the user of display panel 110 needs to share the content of display panel 110 with people around them or when there are no other people around the user of display panel 110, a mode switching signal can be generated by triggering the mode adjustment module. This causes the control module 130 in dynamic viewing angle adjustment mode to adjust the viewing angle switching mode to sharing mode according to the mode switching signal. In sharing mode, the control module will control the display panel 110 to adjust the viewing angle of all display areas to a wide viewing angle.

[0087] When the user of display panel 110 needs to protect privacy, a mode switching signal can be generated by triggering the mode adjustment module. The control module 130 in sharing mode will then adjust the viewing angle switching mode to dynamic viewing angle adjustment mode according to the mode switching signal. This will dynamically adjust the viewing angle of different display areas of display panel 110 and the display position of privacy software according to the positions of people around the user of display panel 110.

[0088] Based on the above embodiments, optionally, the image acquisition module 120 includes a camera, the control module 130 includes a timing controller, and the mode adjustment module includes a trigger switch.

[0089] The camera can capture image information around the display panel 110. In dynamic viewing angle adjustment mode, the timing controller can process the image information, analyze the environment around the display panel 110, confirm the location of people around the user, and dynamically adjust the viewing angle of different display areas of the display panel 110 and the display position of the privacy software based on the location of people around the user. A trigger switch can generate a mode switching signal, causing the timing controller to switch the viewing angle mode from dynamic viewing angle adjustment mode to sharing mode, and from sharing mode back to dynamic viewing angle adjustment mode.

[0090] It should be understood that the various forms of the process shown above can be used, with steps reordered, added, or deleted. For example, the steps described in this utility model can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this utility model can be achieved, and this is not limited herein.

Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors.
