Abstract
Description
Technical Field
[0001] This application relates to the field of display technology, and more particularly to a display device and electronic display equipment. Background Technology
[0002] With the widespread adoption of consumer electronics, users are increasingly using these devices in public spaces, making the need for privacy protection of screen content more urgent. To address this issue, privacy-protecting display technology has emerged. Its core idea is to add a special optical structure layer on top of the display layer, using geometric optics principles to restrict the visible angle of the screen to a narrow range directly in front of the user, allowing light to pass through only in the direction of that opening, thus achieving a side privacy protection effect.
[0003] Currently, mainstream privacy protection solutions mainly include applying physical films and building-in micro-gratings. Physical films increase device thickness and are prone to wear and tear, potentially detaching and compromising the original touchscreen feel, thus affecting the user experience. Built-in micro-gratings, on the other hand, are often limited to densely spaced adjacent pixels. While providing basic privacy protection, they significantly obstruct the effective light-emitting area of each pixel, leading to a severe decrease in screen brightness and a reduction in image quality due to lower pixel density (PPI) and smaller effective display area. Prolonged use can also exacerbate user eye strain.
[0004] Furthermore, both of the aforementioned privacy protection solutions are static structures, meaning their privacy protection function is continuously active and cannot dynamically switch between privacy protection and normal display modes based on the user's situation. In private scenarios where privacy protection is not required, users still have to endure the negative effects of brightness loss and image quality degradation, making it difficult to meet the current demands of consumer electronics devices for intelligent and contextualized displays. Summary of the Invention

[0010] In some embodiments, the privacy layer includes a plurality of first privacy groups and a plurality of second privacy groups. The first privacy groups are arranged at intervals along a first direction, and at least one second privacy group is provided between any two first privacy groups. Both the first and second privacy groups include a plurality of privacy parts arranged along a second direction. When the display device is in a third privacy mode, the second privacy parts in each first privacy group are in a non-transparent state, the first privacy parts in each first privacy group are in a transparent state, and the first and second privacy parts in each second privacy group are in a transparent state.
[0011] In some embodiments, the first privacy screen includes a first sub-privacy screen and a second sub-privacy screen. The first sub-privacy screen is configured to be transparent or opaque under the drive of a first sub-voltage signal, and the second sub-privacy screen is configured to be transparent or opaque under the drive of a second sub-voltage signal. The second privacy screen includes a third sub-privacy screen and a fourth sub-privacy screen. The third sub-privacy screen is configured to be transparent or opaque under the drive of a third sub-voltage signal, and the fourth sub-privacy screen is configured to be transparent or opaque under the drive of a fourth sub-voltage signal. In the orthographic projection on the substrate, the first sub-privacy screen, the third sub-privacy screen, the second sub-privacy screen, and the fourth sub-privacy screen are arranged sequentially in a clockwise direction.
[0012] In some embodiments, the privacy layer includes: a first privacy group and a second privacy group, respectively located at both ends of the privacy layer in a first direction, each including a plurality of privacy parts arranged along the second direction; a third privacy group and a fourth privacy group, respectively located at both ends of the privacy layer in the second direction, each including a plurality of privacy parts arranged along the first direction, wherein the first privacy group, the third privacy group, the second privacy group and the fourth privacy group are arranged sequentially in a clockwise direction within the orthographic projection on the substrate; a fifth privacy group, located in the middle of the privacy layer, including a plurality of privacy parts arranged along the first direction and the second direction; and a sixth privacy group, located at a corner of the privacy layer; wherein, when the display device is in the fourth privacy mode, the first sub-privacy part, the third sub-privacy part and the fourth sub-privacy part in the first privacy group are all exposed. In the non-transparent state, the second sub-spy heads in the first privacy group are all transparent; the second, third, and fourth sub-spy heads in the second privacy group are all opaque, while the first sub-spy head in the second privacy group is all transparent; the first, second, and third sub-spy heads in the third privacy group are all opaque, while the fourth sub-spy head in the third privacy group is all transparent; the first, second, and fourth sub-spy heads in the fourth privacy group are all opaque, while the third sub-spy head in the fourth privacy group is all transparent; the first, second, third, and fourth sub-spy heads in the fifth privacy group are all transparent; and the first, second, third, and fourth sub-spy heads in the sixth privacy group are all opaque.
[0013] In some embodiments, within the orthographic projection on the substrate, the privacy shield at least partially covers the light-emitting unit within the pixel opening corresponding to the color blocking opening that surrounds it.
[0014] In some embodiments, the material of the privacy screen includes at least one of liquid crystal material and electrochromic material.
[0015] To achieve the above objectives, this application also provides an electronic display device, which includes the display device of this application.
[0016] In the display device and electronic display equipment of this application embodiment, the anti-spy part is divided into a first anti-spy part and a second anti-spy part, which can be independently driven by a first voltage signal and a second voltage signal respectively to achieve switching between at least a partially transparent state and a non-transparent state. Users can flexibly control the opening and closing of the anti-spy function in one direction, two directions or multiple directions according to actual privacy protection needs. Compared with anti-spy solutions with a fixed anti-spy range, it is suitable for more privacy protection scenarios and has stronger anti-spy targeting. This application can flexibly control the transparent and non-transparent states of the anti-spy part, realizing the free switching between public display of the screen and personal viewing. It solves the defects of traditional static anti-spy solutions that require the anti-spy function to be continuously turned on, causing users to suffer from brightness loss and image quality degradation even in scenarios where anti-spy is not required. In private scenarios, the anti-spy function can be accurately turned on to prevent the screen content from being viewed by others. In public scenarios, it can switch to normal display mode to ensure the brightness and image quality of the screen's forward display, taking into account both privacy protection and sharing needs.
[0017] This application achieves precise privacy protection by controlling the state of the privacy shield, while minimizing the impact on the normal display of the screen. Compared with the traditional static privacy protection solution, which suffers from deteriorated display effect due to continuous obstruction, this application can flexibly switch according to the needs of the scenario, ensuring that the screen brightness and image quality are not compromised in the normal display mode. This avoids visual fatigue caused by users viewing a screen with degraded image quality and reduced brightness for a long time, thus improving the user experience. Attached Figure Description

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0023] Please see Figure 1, Figure 2 and Figure 3 This application provides a display device 100, which has a first direction X, a second direction Y, and a third direction Z that intersect each other. In this embodiment, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other. The perpendicularity of the first direction X, the second direction Y, and the third direction Z can be understood as the included angle between each pair of the first direction X, the second direction Y, and the third direction Z being 80° to 90°, which is not limited here. The display device 100 includes: a substrate 1, a thin film transistor layer 2, a pixel definition layer 3, a light-emitting layer 4, an encapsulation layer 5, a privacy shield layer 6, and a color resist layer 7.
[0024] Please see Figure 1 and Figure 2 The substrate 1 is made of materials including polyimide, polycarbonate, polyethylene terephthalate, and polyethylene naphthalate, which gives the substrate 1 good impact resistance.
[0025] Please see Figure 1 and Figure 2 Thin-film transistor layer 2 is disposed on substrate 1. Specifically, thin-film transistor layer 2 may include: gate, gate insulating layer, active layer, source, drain, etc., which will not be described in detail here.
[0026] Please see Figure 1 and Figure 2 A pixel definition layer 3 is disposed on the substrate 1. Specifically, the pixel definition layer 3 is disposed on the side of the thin-film transistor layer 2 away from the substrate 1. The pixel definition layer 3 includes a plurality of pixel openings 31 and a plurality of isolation structures 32, with each isolation structure 32 corresponding to one another and arranged around the periphery of the pixel openings 31. The pixel definition layer 3 can be formed of an organic material including resin (such as polyacrylate or polyimide, silica, etc.).
[0027] Please see Figure 1 and Figure 2 The light-emitting layer 4 includes multiple light-emitting units, which are disposed one-to-one within the pixel opening 31. In this embodiment, the light-emitting layer 4 includes a red light-emitting unit 41, a green light-emitting unit 42, and a blue light-emitting unit 43.
[0028] Please see Figure 1 and Figure 2 The display device 100 further includes a first electrode 8, which is disposed between the thin-film transistor layer 2 and the light-emitting layer 4. Specifically, the first electrode 8 can be electrically connected to the drain of the thin-film transistor layer 2. The material of the first electrode 8 includes, but is not limited to, metal. In this embodiment, the material of the first electrode 8 is silver (Ag), thereby giving the first electrode 8 not only good conductivity but also the ability to reflect the light emitted by the light-emitting layer 4, improving the light extraction efficiency of the display device 100.
[0029] Please see Figure 1 and Figure 2 The display device 100 also includes a second electrode 9, which covers the side of the light-emitting layer 4 and the pixel definition layer 3 away from the substrate 1. Since ITO, as a nano-indium tin oxide, has excellent conductivity and light transmittance, the material of the second electrode 9 in this embodiment is preferably ITO.
[0030] In some embodiments, the display device 100 further includes film structures such as a hole injection layer, a hole transport layer, an electron transport layer, and an electron injection layer, which will not be described in detail here.
[0031] Please see Figure 1 and Figure 2 The encapsulation layer 5 is disposed on the side of the second electrode 9 away from the substrate 1. The encapsulation layer 5 includes an organic layer and an inorganic layer, and one or more of either the organic or inorganic layers can be provided. For example, the organic and inorganic layers in the encapsulation layer 5 can be formed by alternating layers. The organic layer is formed of a polymer and can be a single-layer or multi-layer structure formed from any one of polyethylene terephthalate, polyimide, polycarbonate, epoxy resin, polyethylene, and polyacrylate. The inorganic layer can be a single-layer or multi-layer structure including metal oxides or metal nitrides. For example, the inorganic layer may include any one of SiNx, Al2O3, SiO2, and TiO2.
[0032] Please see Figure 1 , Figure 2 and Figure 3 A privacy layer 6 is disposed on the pixel definition layer 3. Specifically, the privacy layer 6 is disposed on the side of the encapsulation layer 5 away from the substrate 1. The privacy layer 6 includes multiple color resist openings 61, multiple privacy shielding portions 63, and multiple spacers 62. The color resist openings 61 are disposed one-to-one with the pixel openings 31, the privacy shielding portions 63 are disposed around the periphery of the color resist openings 61, and the spacers 62 are disposed around the periphery of the privacy shielding portions 63. The spacers 62 can be used to isolate adjacent color resisting units, prevent light crosstalk between adjacent color resisting units, and avoid color mixing problems in the display image caused by crosstalk.
[0033] Please see Figure 4The privacy screen 63 includes a first privacy screen 631 and a second privacy screen 632. The first privacy screen 631 is disposed on both sides of the color-blocking opening 61 in the first direction X, and is configured to be at least partially transparent or opaque under the drive of a first voltage signal. The second privacy screen 632 is disposed on both sides of the color-blocking opening 61 in the second direction Y, and is configured to be at least partially transparent or opaque under the drive of a second voltage signal. In this embodiment, the first privacy screen 631 includes a first sub-privacy screen 6311 and a second sub-privacy screen 6312. The first sub-privacy screen 6311 is configured to be transparent or opaque under the drive of a first sub-voltage signal, and the second sub-privacy screen 6312 is configured to be transparent or opaque under the drive of a second sub-voltage signal. The second privacy screen 632 includes a third sub-privacy screen 6321 and a fourth sub-privacy screen 6322. The third sub-privacy screen 6321 is configured to be transparent or opaque under the drive of a third sub-voltage signal, and the fourth sub-privacy screen 6322 is configured to be transparent or opaque under the drive of a fourth sub-voltage signal. In the orthographic projection on the substrate 1, the first sub-privacy screen 6311, the third sub-privacy screen 6321, the second sub-privacy screen 6312, and the fourth sub-privacy screen 6322 are arranged sequentially in a clockwise direction.
[0034] The privacy screen 63 is made of at least one of liquid crystal material and electrochromic material. In this embodiment, the privacy screen 63 is made of electrochromic material. It is noteworthy that each of the first sub-privacy screen 6311, the second sub-privacy screen 6312, the third sub-privacy screen 6321, and the fourth sub-privacy screen 6322 has a first conductive part and a second conductive part on opposite sides. When no voltage is applied between the first and second conductive parts or a specific low voltage is applied, the electrochromic material is transparent or light-colored, allowing light to pass through freely, and the user can clearly see the content displayed on the screen. When a predetermined voltage is applied between the first and second conductive parts, the electrochromic material undergoes a redox reaction, causing ions and electrons within the material to migrate, resulting in a sharp decrease in its light transmittance. The material quickly darkens (e.g., turns dark blue, black, or dark gray). At this time, the light emitted from the screen is strongly absorbed or blocked by the electrochromic layer, making it impossible for external observers to see the screen content, thus achieving a privacy effect.
[0035] Please see Figure 1 When the privacy screen 63 is transparent, light rays A at small angles can pass through the photoresist layer and enter the user's field of view, while light rays B at large angles can also pass through the privacy screen 63 and enter the user's field of view. At this time, the display device 100 is in sharing mode, which can maintain good image quality while ensuring the brightness of the front display of the screen.
[0036] Please see Figure 2When the privacy screen 63 is in a non-transparent state, light rays A at small angles can pass through the photoresist layer and enter the user's field of view, while light rays B at large angles are blocked by the privacy screen 63 and cannot enter the user's field of view. At this time, the display device 100 is in privacy mode, which can effectively prevent side peeping and ensure the privacy of the content displayed on the front of the screen.
[0037] Please see Figure 1 and Figure 2 In some embodiments, within the orthographic projection on the substrate 1, the privacy shield 63 at least partially covers the light-emitting unit within the pixel opening 31 corresponding to the surrounding color resist opening 61. Thus, when the privacy shield 63 is in a transparent state, it does not significantly affect the light emission angle of the light-emitting unit, allowing the display light to be emitted normally along its original angle. When the privacy shield 63 switches to a non-transparent state, it can effectively block and scatter the side-view light emitted from the edge of the light-emitting unit by covering the portion of the light-emitting unit's edge area, thereby further compressing the side-view visibility angle. This design significantly improves the side-view privacy protection effect while avoiding blocking the core light-emitting area of the light-emitting unit and ensuring that the brightness and image quality of the frontal viewing angle are not affected, achieving a balance and optimization of display performance and privacy protection performance.
[0038] Please see Figure 1 , Figure 2 and Figure 3 The color resist layer 7 includes multiple color resist units, each disposed one-to-one within a color resist opening 61. In this embodiment, the color resist layer 7 includes a red color resist unit 71, a green color resist unit 72, and a blue color resist unit 73. The red color resist unit 71 corresponds one-to-one with the red light-emitting unit 41, the green color resist unit 72 corresponds one-to-one with the green light-emitting unit 42, and the blue color resist unit 73 corresponds one-to-one with the blue light-emitting unit 43.
[0039] Please see Figure 3 When the display device 100 is in sharing mode, each first privacy screen 631 and each second privacy screen 632 is transparent. Specifically, the first sub-privacy screen 6311, the second sub-privacy screen 6312, the third sub-privacy screen 6321, and the fourth sub-privacy screen 6322 of each privacy screen 63 are all transparent. At this time, each first privacy screen 631 and each second privacy screen 632 will not block or attenuate the emitted light from the light-emitting layer 4, which not only ensures the brightness of the front display, but also effectively avoids the loss of image quality caused by light diffraction or scattering, presenting a clear and transparent visual effect.
[0040] Please see Figure 5When the display device 100 is in the first privacy mode, each of the first privacy panels 631 and each of the second privacy panels 632 is opaque. Specifically, the first sub-privacy panels 6311, the second sub-privacy panels 6312, the third sub-privacy panels 6321, and the fourth sub-privacy panels 6322 of each privacy panel 63 are opaque. In this state, large-angle light B is effectively blocked, allowing only small-angle light A to pass through, thereby significantly reducing side visibility and preventing the screen content from being viewed by a side-viewer. This mode is suitable for application scenarios with high privacy protection requirements.
[0041] Please see Figure 6 In some embodiments, the privacy layer 6 includes a plurality of first privacy groups 6301 and a plurality of second privacy groups 6302, the first privacy groups 6301 being along the second direction Y ( Figure 6 The first privacy groups 6301 and the second privacy groups 6302 are arranged at intervals along the first direction X. At least one second privacy group 6302 is provided between any two first privacy groups 6301. Both the first privacy groups 6301 and the second privacy groups 6302 include multiple groups arranged along the first direction X. Figure 6 The privacy screen 63 is arranged horizontally. When the display device 100 is in the second privacy mode, the first privacy screen 631 in each first privacy group 6301 is opaque, the second privacy screen 632 in each first privacy group 6301 is transparent, and the first privacy screen 631 and second privacy screen 632 in each second privacy group 6302 are both transparent. Compared to the first privacy mode, the second privacy mode effectively limits the transmission of large-angle light B and prevents side peeping while reducing the obstruction of front display light. The second privacy mode achieves a better balance between privacy protection and display effect, and is especially suitable for application scenarios with moderate privacy requirements but high demands for brightness and image quality, such as office documents and code editing where the displayed content is mainly horizontal.
[0042] Please see Figure 7 In some embodiments, the privacy layer 6 includes a plurality of first privacy groups 6301 and second privacy groups 6302, wherein the first privacy groups 6301 are along a first direction X ( Figure 7 The first privacy groups 6301 and the second privacy groups 6302 are arranged at intervals along the second direction Y. Figure 7The privacy screen 63 is arranged vertically. When the display device 100 is in the third privacy mode, the second privacy screen 632 in each first privacy group 6301 is opaque, the first privacy screen 631 in each first privacy group 6301 is transparent, and the first privacy screen 631 and second privacy screen 632 in each second privacy group 6302 are both transparent. Compared to the first privacy mode, the third privacy mode effectively limits the transmission of large-angle light B and prevents side peeping while reducing the obstruction of front display light. The third privacy mode achieves a better balance between privacy protection and display effect, and is especially suitable for applications with moderate privacy requirements but high demands for brightness and image quality, such as mobile phone browsing and e-readers where the displayed content is primarily vertical.
[0043] Please see Figure 8 In some embodiments, the privacy layer 6 includes: a first privacy group 6301, a second privacy group 6302, a third privacy group 6303, a fourth privacy group 6304, a fifth privacy group 6305, and a sixth privacy group 6306. The first privacy group 6301 and the second privacy group 6302 are located at opposite ends of the privacy layer 6 in the first direction X, and both the first privacy group 6301 and the second privacy group 6302 include a plurality of privacy-protecting portions 63 arranged along the second direction Y. The third privacy group 6303 and the fourth privacy group 6304 are located at opposite ends of the privacy layer 6 in the second direction Y, and both the third privacy group 6303 and the fourth privacy group 6304 include a plurality of privacy-protecting portions 63 arranged along the first direction X. In the orthographic projection onto the substrate 1, the first privacy group 6301, the third privacy group 6303, the second privacy group 6302, and the fourth privacy group 6304 are arranged sequentially in a clockwise direction. The fifth privacy group 6305 is located in the middle of the privacy layer 6 and includes a plurality of privacy parts 63 arranged along the first direction X and the second direction Y; the sixth privacy group 6306 is located at the corner of the privacy layer 6.
[0044] Please see Figure 8When the display device 100 is in the fourth privacy mode, the first sub-privacy unit 6311, the third sub-privacy unit 6321, and the fourth sub-privacy unit 6322 in the first privacy group 6301 are all opaque, while the second sub-privacy unit 6312 in the first privacy group 6301 is all transparent; the second sub-privacy unit 6312, the third sub-privacy unit 6321, and the fourth sub-privacy unit 6322 in the second privacy group 6302 are all opaque, while the first sub-privacy unit 6311 in the second privacy group 6302 is all transparent; and the first sub-privacy unit 6311, the second sub-privacy unit 6312, and the third sub-privacy unit 6321 in the third privacy group 6303 are all opaque. In the third privacy group 6303, the fourth sub-privacy unit 6322 is transparent; in the fourth privacy group 6304, the first sub-privacy unit 6311, the second sub-privacy unit 6312, and the fourth sub-privacy unit 6322 are opaque, and the third sub-privacy unit 6321 is transparent; in the fifth privacy group 6305, the first sub-privacy unit 6311, the second sub-privacy unit 6312, the third sub-privacy unit 6321, and the fourth sub-privacy unit 6322 are transparent; in the sixth privacy group 6306, the first sub-privacy unit 6311, the second sub-privacy unit 6312, the third sub-privacy unit 6321, and the fourth sub-privacy unit 6322 are opaque. Compared to the first privacy mode, the fourth privacy mode effectively limits the transmission of large-angle light B from all sides of the display device 100 and prevents side peeping, while reducing the obstruction of central display light. The fourth privacy mode is suitable for application scenarios where image quality and brightness are prioritized and privacy protection is a secondary requirement. For example, information display screens in public environments and office monitors in semi-public places.
[0045] In the display device 100 and electronic display equipment of this application embodiment, the privacy shield 63 is divided into a first privacy shield 631 and a second privacy shield 632, which can be independently driven by a first voltage signal and a second voltage signal respectively, realizing the switching between at least a partially transparent state and a non-transparent state. Users can flexibly control the opening and closing of the privacy shield function in one direction, two directions, or multiple directions according to actual privacy protection needs. Compared with the privacy shield solution with a fixed privacy shield range, it is suitable for more privacy protection scenarios and the privacy shield is more targeted. This application can flexibly control the transparent and non-transparent states of the privacy shield 63, realizing the free switching between public display of the screen and personal viewing. It solves the defects of traditional static privacy shield solutions that require the privacy shield function to be continuously turned on, causing users to suffer from brightness loss and image quality degradation even in scenarios where privacy shield is not needed. In private scenarios, the privacy shield function can be accurately turned on to prevent the screen content from being viewed by others. In public scenarios, it can switch to normal display mode to ensure the brightness and image quality of the screen when it is displayed in the forward direction, taking into account both privacy protection and sharing needs.
[0046] This application precisely controls the state of the privacy protection unit 63, achieving accurate privacy protection while minimizing the impact on the normal display of the screen. Compared with the traditional static privacy protection solution, which suffers from deteriorated display effect due to continuous obstruction, this application can flexibly switch according to the needs of the scenario, ensuring that the screen brightness and image quality are not compromised in the normal display mode. This avoids visual fatigue caused by users viewing a screen with degraded image quality and reduced brightness for a long time, thus improving the user experience.
[0047] To achieve the above objectives, this application also provides an electronic display device, which includes the display device 100 of this application.
