Description

Technical Field

[0001] The present disclosure relates to an electronic device. Background Art

[0002] Multi-panel displays (such as those in passenger vehicles) are becoming increasingly common. To minimize the driver's visual impact on the adjacent passenger panel, different panels may require different viewing angle specifications. When operating in low-light conditions, the panel's image may be reflected on the windshield, obstructing the driver's view. Therefore, the viewing angles of the different panels must be limited to appropriate ranges to mitigate this issue. Summary of the Invention

The second display is adjacent to the first display. The back frame is used to support the first and second displays. The protective substrate is disposed on the first and second displays. The first and second displays have different viewing angles, and the first display includes a viewing angle control component.

[0004] According to an embodiment of the present disclosure, an electronic device includes a first panel, a viewing angle control assembly, and a back frame. The first panel includes a non-active area. The viewing angle control assembly includes at least one alignment structure, which overlaps the non-active area when viewed from above. The back frame is used to support the first panel and the viewing angle control assembly. The back frame includes at least one positioning structure for securing the at least one alignment structure.

[0019] The following is a detailed description of the electronic device according to the embodiment of the present disclosure. It should be understood that the following description provides many different embodiments for implementing different implementation methods of some embodiments of the present disclosure. The specific components and arrangements described below are only for a simple and clear description of some embodiments of the present disclosure. Of course, these are only used as examples and are not limitations of the present disclosure. In addition, similar and / or corresponding numbers may be used in different embodiments to indicate similar and / or corresponding components to clearly describe the present disclosure. However, the use of these similar and / or corresponding numbers is only for a simple and clear description of some embodiments of the present disclosure, and does not represent any correlation between the different embodiments and / or structures discussed.

[0020] It should be understood that relative terms, such as "lower" or "bottom" or "higher" or "top", may be used in the embodiments to describe the relative relationship of one component to another component illustrated in the drawings. It is understood that if the device in the drawings is flipped upside down, the component described on the "lower" side will become the component on the "higher" side. The embodiments of the present disclosure can be understood in conjunction with the drawings, and the drawings of the present disclosure are also considered part of the disclosure. It should be understood that the drawings of the present disclosure are not drawn to scale. In fact, the size of the components may be arbitrarily enlarged or reduced in order to clearly show the features of the present disclosure.

[0021] A structure (or layer, component, substrate) described in the present disclosure is located on / above another structure (or layer, component, substrate), which may refer to the two structures being adjacent and directly connected, or it may refer to the two structures being adjacent but not directly connected. Indirect connection means that there is at least one intermediary structure (or intermediary layer, intermediary component, intermediary substrate, intermediary gap) between the two structures, the lower surface of one structure is adjacent to or directly connected to the upper surface of the intermediary structure, and the upper surface of the other structure is adjacent to or directly connected to the lower surface of the intermediary structure. The intermediary structure can be composed of a single-layer or multi-layer physical structure or a non-physical structure, without limitation. In the present disclosure, when a certain structure is disposed "on" another structure, it may refer to a certain structure being "directly" on the other structure, or to a certain structure being "indirectly" on the other structure, that is, at least one structure is sandwiched between the certain structure and the other structure.

[0022] Furthermore, it should be understood that ordinal numbers such as "first" and "second" used in the specification and claims to modify components do not, by themselves, imply or represent any prior ordinal number of the component(s), nor do they represent the order of one component relative to another, or the order of manufacturing methods. Such ordinal numbers are used solely to clearly distinguish a component with a certain name from another component with the same name. The claims and the specification may not use the same terms; for example, the first component in the specification may be the second component in the claims.

[0023] In some embodiments of the present disclosure, terms related to bonding and connection, such as "connected" and "interconnected," unless otherwise specified, may refer to two structures being in direct contact, or may also refer to two structures not being in direct contact, with another structure disposed between the two structures. Furthermore, such terms related to bonding and connection may also include situations where both structures are movable or both structures are fixed. Furthermore, the terms "electrically connected" or "coupled" include any direct and indirect electrical connection means.

[0024] As used herein, the terms "about," "substantially," and "approximately" generally mean within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range. Unless otherwise specified, the phrase "a range between a first value and a second value" means that the range includes the first value, the second value, and any values ​​therebetween. Furthermore, any two values ​​or directions used for comparison may have a certain degree of error. If the first value is equal to the second value, it implies that there may be a certain degree of error between the first and second values. If the first direction is perpendicular to the second direction, the angle between the first and second directions may be between 80 and 100 degrees. If the first direction is parallel to the second direction, the angle between the first and second directions may be between 0 and 10 degrees. In this disclosure, the phrases "a given range is between a first value and a second value" or "a given range falls within the range between the first value and the second value" mean that the given range includes the first value, the second value, and any values ​​therebetween.

[0025] Furthermore, according to embodiments of the present disclosure, the thickness, length, width of each component, or the distance and angle between components can be measured using an optical microscope (OM), a scanning electron microscope (SEM), an α-step thin film thickness profilometer, an ellipsometer, or other suitable methods. Specifically, according to some embodiments, a scanning electron microscope can be used to obtain a cross-sectional image of the structure and measure the thickness, length, width, or the distance and angle between components.

[0026] Certain words are used throughout this disclosure and in the claims that follow to refer to specific components. It will be understood by those skilled in the art that electronic equipment manufacturers may refer to the same components by different names. It is not intended herein to distinguish between components that have the same function but different names. In the following description and claims, words such as "include", "comprises", and "have" are open-ended words and should therefore be interpreted as meaning "including but not limited to..." Therefore, when the terms "include", "comprises", and / or "have" are used in the description of this disclosure, they specify the presence of corresponding features, regions, steps, operations, and / or components, but do not exclude the presence of one or more corresponding features, regions, steps, operations, and / or components.

Figure 7A as well as Figure 7B The following are cross-sectional schematic diagrams of two electronic devices according to the fifth and sixth embodiments of the present disclosure. It should be noted that the following embodiments may utilize features from several different embodiments to create other embodiments without departing from the spirit of the present disclosure. Features from various embodiments may be mixed and matched as needed, as long as they do not violate the spirit of the invention or conflict with it.

[0034] Please refer to Figure 1A as well as Figure 1B The electronic device 1 may include a first display 10, a second display 11, a back frame 12, and a protective substrate 13. The second display 11 is adjacent to the first display 10. The back frame 12 is used to support the first display 10 and the second display 11. The protective substrate 13 is disposed on the first display 10 and the second display 11. The first display 10 and the second display 11 have different viewing angles, and the first display 10 includes a viewing angle control component 100.

[0035] Specifically, the first display 10 and the second display 11 are used to display images. The first display 10 and the second display 11 may comprise self-luminous displays or non-luminous displays. Self-luminous displays may include, but are not limited to, light-emitting diode displays, organic light-emitting diode displays, sub-millimeter light-emitting diode displays, micro-light-emitting diode displays, or quantum dot light-emitting diode displays. Non-luminous displays may include, but are not limited to, liquid crystal displays or other suitable displays.

[0036] Take non-self-luminous display as an example, Figure 1BAs shown, in addition to the viewing angle control component 100, the first display 10 may also include a light source component 101 (for example, including a circuit board (not shown) and a plurality of light-emitting units (not shown) disposed on the circuit board), an optical component 102, an optical component 103, an optical component 104, a first panel 105 and / or a touch component 106, but the present invention is not limited thereto. Any of the above components may be removed or other components may be added as needed. The light source component 101 is used to provide light. For example, although not shown, the light source component 101 may include a plurality of light-emitting diodes or other suitable light-emitting components. For example, the plurality of light-emitting diodes may be arranged in an array in the first direction D1 and the second direction D2, but the present invention is not limited thereto and may be arranged in other ways as needed. The first direction D1 and the second direction D2 are, for example, both perpendicular to the top-viewing direction of the electronic device 1 (such as the third direction D3), and the first direction D1 is different from the second direction D2. For example, the first direction D1 and the second direction D2 are perpendicular to each other, but the present invention is not limited thereto. The above-mentioned viewing angle control component 100, light source component 101, optical component 102, optical component 103, and optical component 104 are combined into a backlight module, but are not limited thereto. The backlight module can add or omit any of the above-mentioned components according to needs. Figure 1B The backlight module shown is exemplified as a direct-lit backlight module, but the invention is not limited thereto and can be modified to an edge-lit backlight module according to requirements.

[0037] In some embodiments, the back frame 12 may include a groove G1 for accommodating the light source assembly 101, and the light source assembly 101 may be secured to the back frame 12 via an attachment AD1, but the present invention is not limited thereto. The attachment AD1 may include double-sided adhesive tape, double-sided adhesive tape, curable adhesive (thermal curing, light curing, moisture curing, or other suitable curing adhesive), or other adhesive material. The attachment AD1 may include transparent or non-transparent adhesive material.

[0038] The optical assembly 102 is disposed above the light source assembly 101. In some embodiments, the width of the optical assembly 102 may be greater than the width of the light source assembly 101 along the first direction D1 or the second direction D2. In some embodiments, the back frame 12 may include a platform portion P1 for supporting the optical assembly 102. In some embodiments, the platform portion P1, for example, surrounds the groove G1 and protrudes relative to the groove G1, so that the optical assembly 102 disposed on the platform portion P1 can maintain an appropriate distance from the light source assembly 101, thereby facilitating heat dissipation from the light source assembly 101 or alleviating thermal deformation of the optical assembly 102, but the present invention is not limited thereto. Figure 1BThe shape of the platform portion P1 can be adjusted as needed. In some embodiments, the optical assembly 102 can be secured to the platform portion P1 via an attachment AD2, but this is not a limitation. The attachment AD2 can be, for example, annular or divided into multiple sub-sections. The material of the attachment AD2 can refer to that of the attachment AD1 and will not be repeated here. In some embodiments, the back frame 12 can be comprised of a single material or a composite material, such as a metal material, a polymer material, a plastic material, a ceramic material, or other suitable materials.

[0039] In some embodiments, the optical component 102 may include a light guide plate, other light guide components, or other suitable optical sheets, but is not limited thereto. Figure 1B The light source assembly 101 is shown to be disposed below the optical assembly 102, i.e., a direct-lit backlight module architecture is adopted. However, in other embodiments not shown, the light source assembly 101 may be disposed beside the side of the optical assembly 102, i.e., an edge-lit backlight module architecture is adopted.

[0040] Optical assembly 103 is disposed on optical assembly 102. In some embodiments, although not shown, optical assembly 103 may be optionally secured to optical assembly 102 via a transparent adhesive (not shown). The transparent adhesive may include, but is not limited to, optically clear adhesive (OCA), optically clear resin (OCR), other suitable adhesives, or combinations thereof. Optical assembly 103 may include, but is not limited to, a diffuser to enhance light uniformity. Optical assembly 103 may be replaced with other suitable functional sheets as needed.

[0041] In some embodiments, the optical assembly 104 is disposed on the optical assembly 103. In some embodiments, although not shown, the optical assembly 104 can be fixed to the optical assembly 103 via a light-transmitting attachment. The optical assembly 104 can include a prism sheet, such as a brightness enhancement film (BEF), or other suitable functional sheet, but is not limited thereto.

[0042] In some embodiments, the viewing angle control component 100 is disposed on the optical component 104. In some embodiments, although not shown, the viewing angle control component 100 can be fixed to the optical component 104 by a light-transmitting attachment. The viewing angle control component 100 is used to control the viewing angle range of the first display 10. For example, the viewing angle control component 100 may include an electrically controlled viewing angle control component or a non-electrically controlled viewing angle control component. The electrically controlled viewing angle control component may include a viewing angle control component containing any suitable liquid crystal material, or a liquid viewing angle control component containing other materials (dyes), but is not limited thereto. The non-electrically controlled viewing angle control component may include a non-electrically controlled viewing angle control component containing multiple light-shielding portions, such as a Louver film or other suitable structure, but is not limited thereto. The use of a non-electrically controlled viewing angle control component helps to achieve thinning and / or miniaturization of the electronic device 1.

[0043] Take the non-electrically controlled viewing angle control component as an example, Figure 5A or Figure 5B As shown, the viewing angle control assembly 100 may include a light shielding portion 1000 , a protective layer 1001 , a protective layer 1002 , a reflective polarizer 1003 , a light-transmitting attachment 1004 and / or a light-transmitting attachment 1005 , but is not limited thereto. Figure 5B The structure of the viewing angle control component is only an example, and any component can be removed or other components can be added according to needs.

[0044] In some embodiments, the light-shielding portion 1000 may include a light-transmitting layer 1000A and a plurality of light-shielding structures 1000B embedded in the light-transmitting layer 1000A. The material of the light-transmitting layer 1000A may include a light-transmitting organic or inorganic material, such as, but not limited to, a resin or other light-transmitting material. The material of the plurality of light-shielding structures 1000B may include black ink or other light-absorbing materials. In some embodiments, a groove may be formed in the light-transmitting layer 1000A and then filled with a light-absorbing material to form the light-shielding portion 1000, but not limited to this. In some embodiments, a light-transmitting layer 1000A may be provided between the plurality of light-shielding structures 1000B, but not limited to this. In some embodiments, in the third direction D3, the thickness H of the light-shielding structure 1000B may be less than or equal to the thickness H1 of the light-transmitting layer 1000A.

[0045] like Figure 5A or Figure 5BAs shown, the plurality of light-shielding structures 1000B may be arranged sequentially in a first direction D1 and extend in a second direction D2 to limit the viewing angle range in the first direction D1, but the present invention is not limited thereto. Alternatively, although not shown, the plurality of light-shielding structures 1000B may be arranged sequentially in a second direction D2 and extend in the first direction D1 to limit the viewing angle range in the second direction D2. However, the viewing angle limitation range of the present disclosure is not limited to the first direction D1 or the second direction D2; that is, the arrangement direction of the plurality of light-shielding structures 1000B may be adjusted as needed.

[0046] The viewing angle ranges in different directions can be adjusted by adjusting the design parameters or arrangement of the light shielding structure 1000B. The design parameters may include, but are not limited to, a first base angle α of the light shielding structure 1000B, a second base angle β of the light shielding structure 1000B, a width W1 of a first surface BS1 of the light shielding structure 1000B in the first direction D1 (the surface adjacent to the back frame 12 or away from the viewing side VS of the electronic device), a width W2 of a second surface BS2 of the light shielding structure 1000B in the first direction D1 (the surface away from the back frame 12 or near the viewing side VS of the electronic device), a thickness H of the light shielding structure 1000B in the third direction D3, a distance W3 between the first surfaces BS1 of two adjacent light shielding structures 1000B in the first direction D1, a distance W4 between the second surfaces BS2 of two adjacent light shielding structures 1000B in the first direction D1, a pitch P between two adjacent light shielding structures 1000B in the first direction D1, and a cross-sectional shape of the light shielding structure 1000B. The pitch P between two adjacent light shielding structures 1000B is defined as the distance between the same sides or centers of the two adjacent light shielding structures 1000B. Figure 5A For example, it is defined by the same side (right side) of two adjacent light-shielding structures 1000B.

[0047] In some embodiments, as Figure 5A As shown in FIG, the first base angle α may be different from the second base angle β. In other embodiments, as shown in FIG. Figure 5B As shown, the first base angle α may be the same as the second base angle β. In some embodiments, the first base angle α and / or the second base angle β may be greater than 0 degrees and less than or equal to 90 degrees. In some embodiments, as Figure 5A as well as Figure 5B As shown, the width W1 of the first surface BS1 may be different from the width W2 of the second surface BS2, so that the cross-sectional shape of the light shielding structure 1000B is trapezoidal, but not limited thereto. In other embodiments, although not shown, the width W1 of the first surface BS1 may be the same as the width W2 of the second surface BS2, so that the cross-sectional shape of the light shielding structure 1000B is rectangular, but not limited thereto. In some embodiments, as Figure 5AAs shown, two adjacent light shielding structures 1000B in the first direction D1 may be asymmetric structures. Figure 5B As shown, two adjacent light shielding structures 1000B in the first direction D1 may be symmetrical structures. Figure 5A as well as Figure 5B As shown, the thickness H may be greater than the pitch P, the width W1 of the first surface BS1 and / or the distance W3. In some embodiments, the ratio of the thickness H to the pitch P may be greater than 1 and less than or equal to 10, or may be greater than 2 and less than or equal to 8, or may be greater than 3 and less than or equal to 7, but is not limited thereto. In some embodiments, the distance W3 may be greater than or equal to the width W1. In some embodiments, the distance W3 may be less than or equal to the width W1. In some embodiments, the ratio of the distance W3 to the width W1 may be greater than or equal to 0.5 and less than or equal to 2, or greater than or equal to 0.75 and less than or equal to 1.5, but is not limited thereto. In some embodiments, the pitch P may be designed to be smaller than the first panel 105 (refer to FIG. 1 ). Figure 1B ) pixel size to reduce moiré patterns, but is not limited thereto. In some embodiments, pitch P may be between 10 μm and 70 μm (10 μm ≤ pitch P ≤ 70 μm), between 20 μm and 60 μm (20 μm ≤ pitch P ≤ 60 μm), or between 30 μm and 40 μm (30 μm ≤ pitch P ≤ 40 μm), for example, but not limited to, 38.5 μm.

[0048] In some embodiments, the protective layer 1001 is disposed on the viewing side VS of the light shielding portion 1000, while the protective layer 1002 is disposed on the side of the light shielding portion 1000 away from the viewing side VS. The reflective polarizer 1003 is disposed between the protective layer 1002 and the light shielding portion 1000 and is secured to the light shielding portion 1000 via a transparent adhesive 1004. The protective layer 1002 is secured to the reflective polarizer 1003 via a transparent adhesive 1005, but the present invention is not limited thereto. In other embodiments, the reflective polarizer 1003 may be replaced with another light source film.

[0049] The material of the protective layer 1001 and / or the protective layer 1002 may include, but is not limited to, a light-transmitting inorganic or organic material, such as plastic, resin, or other suitable materials. The material of the light-transmitting adhesive 1004 and the light-transmitting adhesive 1005 may include, but is not limited to, optically transparent adhesive or optically transparent resin. In some embodiments, the viewing angle control assembly 100 includes a first surface S1 adjacent to the protective substrate 13 and a second surface S2 opposite to the first surface S1. In other words, the viewing angle control assembly 100 includes a first surface S1 adjacent to the viewing side VS of the electronic device and a second surface S2 opposite to the first surface S1. The haze of the first surface S1 may be greater than the haze of the second surface S2. In some embodiments, the haze of the first surface S1 may be less than or equal to 80%, and the haze of the second surface S2 may be greater than 0 and less than or equal to 10%. In some embodiments, the haze of the first surface S1 may be less than or equal to 75%, less than or equal to 70%, or less than or equal to 65%, but is not limited thereto.

Figure 5A or Figure 5B For example, the first surface S1 of the viewing angle control component 100 may be Figure 5A or Figure 5B The upper surface of the middle protective layer 1001 and the second surface S2 of the viewing angle control component 100 may be Figure 5A or Figure 5B The lower surface of the protective layer 1002. In some embodiments, the upper surface of the protective layer 1001 and the lower surface of the protective layer 1002 may be treated with a haze treatment to reduce moiré patterns, prevent scratches, and / or conceal blemishes, but are not limited thereto. Furthermore, by designing the haze of the first surface S1 to be greater than the haze of the second surface S2 and / or the haze of the first surface S1 to be less than or equal to 80%, the light dispersion caused by excessive haze, which in turn adversely affects viewing angle control, can be reduced. Furthermore, by designing the haze of the second surface S2 to be greater than 0 and less than or equal to 10%, the significant light loss caused by incident light passing through the second surface S2 can be reduced. This haze design allows a majority of light to pass through the second surface S2. For example, the haze of the first surface S1 may be 40%, 45%, 50%, 55%, or 60%, and the haze of the second surface S2 may be 5%, 7%, or 9%, but are not limited thereto.

[0050] Please refer to Figure 1A as well as Figure 1B, the first panel 105 and the touch component 106 are sequentially arranged above the viewing angle control component 100, but are not limited to this. In some embodiments, the touch component 106 can be fixed to the surface of the protective substrate 13 facing the viewing angle control component 100 by a light-transmitting adhesive AD3, but are not limited to this. In some embodiments, the first panel 105 can be fixed to the surface of the touch component 106 facing the viewing angle control component 100 by a light-transmitting adhesive AD4, and the protective substrate 13 can be fixed to the back frame 12 by an adhesive AD5 (patterned adhesive), but are not limited to this. In other words, the touch component 106 can be arranged between the protective substrate 13 and the first panel 105, the touch component 106 and the protective substrate 13 are fixed by the light-transmitting adhesive AD3, and the touch component 106 and the first panel 105 are fixed by the light-transmitting adhesive AD4. In some embodiments, the touch component 106 and / or the first panel 105, for example, are not in contact with the back frame 12, i.e., in the first direction D1 or the second direction D2, a distance (greater than 0) is separated from the back frame 12, but the present invention is not limited thereto. In other embodiments (not shown), the touch component 106 and / or the first panel 105, for example, are in partial contact with the back frame 12, but the present invention is not limited thereto. The protective substrate 13 may include a rigid substrate, such as a glass substrate, a ceramic substrate, a plastic substrate, or other suitable materials, but the present invention is not limited thereto. The material of the plastic substrate may include polycarbonate (PC), polyimide (PI), polypropylene (PP), polyethylene terephthalate (PET), other suitable flexible materials, or a combination of the foregoing materials, but the present invention is not limited thereto. The light-transmitting adhesive AD3 and / or the light-transmitting adhesive AD4 may include optically transparent adhesive or optically transparent resin, but the present invention is not limited thereto. By fixing the first panel 105 to the protective substrate 13, the problem of scratches caused by the first panel 105 contacting the viewing angle control element 100 can be improved, thereby improving the performance of the electronic device.

[0051] The touch component 106 may include a self-capacitive touch component or a mutual-capacitive touch component, and the touch component 106 may include a plurality of touch electrodes (not shown) to implement a physical touch or a floating touch function, but is not limited thereto.

[0052] The first panel 105 is a display panel, such as a liquid crystal display panel, but not limited thereto. The first panel 105 may have an active region R11 and an inactive region R12 adjacent to the active region R11. The active region R11 may be used to display images (or other functional applications, such as touch or detection), while the inactive region R12 may be used to set peripheral circuits (not shown). In some embodiments, Figure 1A As shown, the inactive region R12 may be adjacent to at least one side of the active region R11. The inactive region R12 may surround the active region R11, for example, but is not limited thereto. Figure 1A In order to clearly show the relative arrangement relationship between the viewing angle control element 100 and the back frame 12 , the edge of the first panel 105 is shown by a thin solid line, and the boundary BR1 between the active area R11 and the inactive area R12 is shown by a thin dotted line.

[0053] In some embodiments, as Figure 1A As shown, the viewing angle control assembly 100 may include at least one alignment structure AL1. When viewed from above (e.g., the third direction D3) the at least one alignment structure AL1 overlaps the inactive region R12. In some embodiments, the at least one alignment structure AL1 may be a recess (not shown), a protrusion, or a through-hole in the viewing angle control assembly 100. The back frame 12 may include at least one positioning structure PS1 for securing the at least one alignment structure AL1. Figure 1A The schematic diagram shows one alignment structure AL1 and one positioning structure PS1, where the alignment structure AL1 is a protrusion of the viewing angle control assembly 100, and the positioning structure PS1 is a recessed portion having a shape substantially complementary to the protrusion, but the embodiments are not limited thereto. For example, although not shown, the number of alignment structures AL1 and positioning structures PS1 may be greater than one. Furthermore, the alignment structure AL1 may be a recessed portion of the viewing angle control assembly 100, and the positioning structure PS1 may be a protrusion having a shape substantially complementary to the recessed portion, but the embodiments are not limited thereto. Alternatively, the alignment structure AL1 may be a through-hole in the viewing angle control assembly 100, and the positioning structure PS1 may be a columnar structure extending through the through-hole, but the embodiments are not limited thereto.

[0054] In some embodiments, the alignment structure AL1, in addition to assisting with alignment, can also be used to identify the axial direction of the light shielding portion 1000 of the viewing angle control assembly 100 or the front and back surfaces of the viewing angle control assembly 100, thereby facilitating alignment of non-rectangular or rectangular electronic devices. That is, regardless of whether the electronic device 1 is rectangular, circular, triangular, other polygonal, or irregular in shape, designing the viewing angle control assembly 100 with the aforementioned alignment structure can improve the accuracy of alignment and assembly between the viewing angle control assembly 100 and the back frame 12 or other adjacent components (e.g., the first panel 105).

[0055] In other embodiments, although not shown, similar to the viewing angle control component 100, the optical component 102, the optical component 103 and / or the optical component 104 may also include at least one alignment structure. The at least one alignment structure may be a recessed portion (not shown), a protruding portion or a through hole. By designing at least one alignment structure in the above-mentioned optical components, the accuracy of alignment and assembly between the above-mentioned optical components and the back frame 12 or other adjacent components (such as the first panel 105) can be improved.

[0056] Similarly, the second display 11 can also be a self-luminous display or a non-self-luminous display. Figure 1B As shown, the second display 11 may include, but is not limited to, a light source assembly 111, an optical assembly 112, an optical assembly 113, an optical assembly 114, an optical assembly 110, a second panel 115, and a touch assembly 116. The light source assembly 111, the optical assembly 112, the optical assembly 113, the optical assembly 114, and the optical assembly 110 may be combined into, for example, a backlight module, but is not limited thereto. The backlight module may include or omit any of the aforementioned components as needed.

[0057] The details of the light source assembly 111 can be found in the description of the light source assembly 101 and will not be repeated here. In some embodiments, the back frame 12 may further include a groove G2 for accommodating the light source assembly 111. The light source assembly 111 may be secured in the groove G2 via an attachment AD6, but this is not limited to this embodiment. The material of the attachment AD6 may refer to that of the attachment AD1 and will not be repeated here.

[0058] The optical assembly 112 is disposed above the light source assembly 111. In some embodiments, the width of the optical assembly 112 may be greater than the width of the light source assembly 111 along the first direction D1 or the second direction D2. In some embodiments, the groove G1 and the groove G2 are not connected to each other. In some embodiments, the back frame 12 may further include a platform portion P2 for supporting the optical assembly 112. In some embodiments, the platform portion P2 may, for example, surround the groove G2 and protrude relative to the groove G2, allowing the optical assembly 112, disposed on the platform portion P2, to maintain an appropriate distance from the light source assembly 111, thereby facilitating heat dissipation from the light source assembly 111 or helping to alleviate thermal deformation of the optical assembly 112. In other embodiments, the optical assembly 112 and the light source assembly 111 may selectively be partially in contact. In some embodiments, the optical assembly 112 may be secured to the platform portion P2 via an attachment AD7, but this is not limited to this. The material of the attachment AD7 may refer to that of the attachment AD1 and will not be repeated here. The attachment AD7 may, for example, be annular or divided into multiple sub-portions.

[0059] The optical component 112 may include a light guide plate, other light guide components or other suitable optical sheets, but is not limited thereto. Figure 1B The light source assembly 111 is shown to be disposed below the optical assembly 112, i.e., a direct-lit backlight module architecture is adopted. However, in other embodiments not shown, the light source assembly 111 may be disposed beside the side of the optical assembly 112, i.e., an edge-lit backlight module architecture is adopted.

[0060] Optical assembly 113 is disposed on optical assembly 112. In some embodiments, although not shown, optical assembly 113 can be secured to optical assembly 112 via a light-transmitting attachment. Furthermore, optical assembly 113 can include a diffuser to improve light uniformity, but is not limited thereto. Optical assembly 113 can be replaced with other suitable functional sheets as needed.

[0061] In some embodiments, the optical component 114 is disposed on the optical component 113. In some embodiments, although not shown, the optical component 114 can be fixed to the optical component 113 via a light-transmitting attachment. The optical component 114 can include a prism sheet, such as a brightness enhancement film, but is not limited thereto.

[0062] Optical assembly 110 is disposed on optical assembly 114. In some embodiments, although not shown, optical assembly 110 can be fixed to optical assembly 114 via a light-transmitting attachment. Optical assembly 110 is, for example, a reflective dual brightness enhancement film (DBEF) or other suitable functional film, but is not limited thereto.

[0063] In some embodiments, the optical element 110 of the second display 11 and the viewing angle control element 100 of the first display 10 are, for example, substantially coplanar. For example, in the third direction D3, the distance DT2 between the optical element 110 and the protective substrate 13 may be substantially equal to the distance DT1 between the viewing angle control element 100 and the protective substrate 13, but this is not limited thereto. Furthermore, the protective substrate 13 includes a viewing surface 13S (i.e., the surface facing away from the back frame 12). A virtual plane SS is substantially parallel to the viewing surface 13S of the protective substrate 13, and the virtual plane SS passes through the viewing angle control element 100 and the optical element 110. In other embodiments, although not shown, the optical element 110 may be omitted, so that the second display 11 is flush with the viewing angle control element 100 and is free space. In some embodiments, in the third direction D3, the distance (not shown) between the optical element 110 and the second panel 115 may be substantially equal to the distance (not shown) between the viewing angle control element 100 and the first panel 15. In some embodiments, in the third direction D3 , the thickness (not labeled) of the optical component 110 and the thickness (not labeled) of the viewing angle control component 100 may be the same or different.

[0064] In some embodiments, the second panel 115 and the touch component 116 are sequentially disposed above the optical component 110. In some embodiments, the touch component 116 can be secured to the surface of the protective substrate 13 facing the optical component 110 via a light-transmitting adhesive AD8, and the second panel 115 can be secured to the surface of the touch component 116 facing the optical component 110 via a light-transmitting adhesive AD9, but the present invention is not limited thereto. The materials of the light-transmitting adhesive AD8 and the light-transmitting adhesive AD9 can refer to the description of the light-transmitting adhesive AD3 or the light-transmitting adhesive AD4, but the present invention is not limited thereto. In other words, the touch component 116 can be disposed between the protective substrate 13 and the second panel 115, with the touch component 116 secured to the protective substrate 13 via the light-transmitting adhesive AD8, and the touch component 116 secured to the second panel 115 via the light-transmitting adhesive AD9. In some embodiments, the touch component 116 and / or the second panel 115 are, for example, not in contact with the back frame 12, i.e., in the first direction D1 or the second direction D2, the touch component 116 and / or the second panel 115 are, for example, separated from the back frame 12 by a distance (greater than 0), but not limited thereto. In other embodiments (not shown), the touch component 116 and / or the second panel 115 are, for example, partially in contact with the back frame 12, but not limited thereto. In addition, the second panel 115 is, for example, not in contact with the optical component 110, i.e., in the third direction D3, there is a distance between the second panel 115 and the optical component 110 to reduce the problem of scratches between the second panel 115 and the optical component 110 caused by pressing, thereby improving the display effect. The touch component 116 can refer to the description of the touch component 106. The second panel 115 can refer to the description of the first panel 105. The second panel 115 can have an active area R21 and an inactive area R22 adjacent to the active area R21. The active region R21 may be used to display images (or other functional applications, such as touch or detection), while the inactive region R22 may be used to set peripheral circuits (not shown). Figure 1A As shown, the inactive region R22 may be adjacent to at least one side of the active region R21. The inactive region R22 may surround the active region R21, for example, but is not limited thereto. Figure 1A In order to clearly illustrate the relative arrangement relationship between the optical component 110 and the back frame 12 , the edge of the second panel 115 is shown with a thin solid line, and the boundary BR2 between the active area R21 and the inactive area R22 is shown with a thin dotted line.

[0065] Although not shown, the optical components 110, 112, 113, and 114 may also include at least one alignment structure, and the back frame 12 may include at least one positioning structure (such as the positioning structure PS2 shown in FIG1 ) for fixing to the at least one alignment structure to facilitate assembly. For details, please refer to the above.

[0066] Figure 1C yes Figure 1A The brightness viewing angle curve diagram of the first display and the second display. Figure 1C In FIG. 1 , curve C1 is a brightness viewing angle curve of the first display 10 , and curve C2 is a brightness viewing angle curve of the second display 11 . Figure 1C The vertical axis L% is the normalized brightness percentage. Figure 1C It can be found that the first display 10 and the second display 11 can, for example, have a maximum luminance percentage when viewed straight ahead (i.e., θ = 0° or |θ| is between ±10°), but this is not limited to this. The luminance viewing angle curves (curves C1 and C2) can be measured, for example, using a goniometer (e.g., model DMS-803, but not limited thereto), an imaging spectrocolorimeter (e.g., a conometer), or other similar instrument. For example, curves C1 and C2 can be obtained by normalizing optical plots (e.g., cono plots) measured approximately at the center of the first display 10 and the second display 11, respectively. The luminance viewing angle curves (curves C1 and C2) are, for example, measured when the first display 10 and the second display 11 are driven to their maximum brightness or grayscale.

[0067] Please also refer to Figure 1B and Figure 1C The brightness at θ=0° refers to the brightness measured along the third direction D3, and |θ| represents the angle between the measurement direction and the third direction D3. The larger |θ| is, the more parallel the viewing angle is to the plane (the plane formed by the first direction D1 and the second direction D2). Figure 1B The brightness measured at θ=-X° and θ=X° can be exemplified by the brightness measured at viewing angles at opposite sides.

[0068] By designing that the first display 10 includes the viewing angle control component 100 of the present disclosure, the electronic device 1 can provide a multi-screen display with different viewing angles, that is, the viewing angles of the first display 10 and the second display 11 are different. Figure 1C As shown, the difference in viewing angle ranges of the first display 10 and the second display 11 means that the difference in brightness percentage of the respective brightness viewing angle curves of the first display 10 and the second display 11 at a viewing angle θ of 30 degrees (i.e., θ = ±30°) is greater than or equal to 5%. Figure 1CIt can be found that at a viewing angle θ of 30 degrees (i.e., θ = ±30°), the luminance percentage difference between curves C1 and C2 is greater than or equal to 5%. For example, at θ = 30°, the luminance percentage difference between curves C1 and C2 is approximately 20%, and at θ = -30°, the luminance percentage difference between curves C1 and C2 is approximately 30%, but the present invention is not limited thereto. In some embodiments, the luminance percentage difference between the luminance viewing angle curves of the first display 10 and the second display 11 at a viewing angle θ of 30 degrees (i.e., θ = ±30°) is greater than or equal to 5% and less than or equal to 60%, but the present invention is not limited thereto. In some embodiments, the luminance percentage difference between the luminance viewing angle curves of the first display 10 and the second display 11 at a viewing angle θ of 30 degrees (i.e., θ = ±30°) is greater than or equal to 5% and less than or equal to 55%, but the present invention is not limited thereto. In some embodiments, the brightness percentage difference between the first display 10 and the second display 11 at a viewing angle θ of 30 degrees (i.e., θ = ±30°) is greater than or equal to 5% and less than or equal to 50%, but the present invention is not limited thereto. By designing the brightness percentage difference between the brightness viewing angle curves at a viewing angle θ of 30 degrees (i.e., θ = ±30°), the first display 10 and the second display 11 have different viewing angle ranges. Figure 1C For example only, the brightness percentage difference between the curve C1 and the curve C2 can be adjusted according to the needs, that is, the L% corresponding to the curve C1 and the curve C2 at θ=±30° is not limited to Figure 1C In addition, the setting of the viewing angle control component 100 can make the viewing angle range of the first display 10 different from (for example, smaller than) the viewing angle range of the second display 11. For example, Figure 1C It can be found that when L% is 50%, the viewing angle range of curve C2 (eg, +25° to -25°) is larger than that of curve C1 (eg, +23° to -18°), but the present invention is not limited thereto. Figure 1C The difference in viewing angle range between curves C1 and C2 at L% of 50% is only an example and can be adjusted according to needs. Figure 1C For example only, the relationship between L% and viewing angle of curves C1 and C2 can be adjusted according to needs.

[0069] In some embodiments, the first display 10 is, for example, a display corresponding to the passenger side of a vehicle-mounted device, and the second display 11 is, for example, a display corresponding to the main driver's side of a vehicle-mounted device. The viewing angle control component 100 can be used to reduce the viewing angle range of the first display 10 in the first direction D1, thereby reducing the interference of the image of the first display 10 on the main driver's side, but the present invention is not limited thereto. In addition, the viewing angle control component 100 can also reduce the interference of the image of the first display 10 reflected on the windshield on the main driver's side. Under this design, the driving environment (light brightness) is not restricted. The first display 10 can use a high-contrast direct-type backlight display, but the present invention is not limited thereto. In other embodiments, the first display 10 and the second display 11 can also be used in devices other than vehicle-mounted devices.

[0070] The viewing angle control assembly's parameters can be adjusted to accommodate the diverse design of any mechanical structure within a ride. For example, the design parameters of the viewing angle control assembly can be adjusted to accommodate differences in the display's placement, the size or shape of the display's installation area, and so on. Furthermore, the thinness of the viewing angle control assembly facilitates the implementation of thinner, custom-shaped, and / or curved designs for electronic devices.

[0071] Please refer to Figure 2A as well as Figure 2B , the electronic device 1A and Figure 1A as well as Figure 1B The main difference of the electronic device 1 is that the optical component 110 in the second display 11 is replaced with a viewing angle control component 110A, and the viewing angle control component 100 and the viewing angle control component 110A limit the viewing angle in different directions. For example, the viewing angle control component 100 limits the viewing angle range of the first display 10 in the first direction D1, while the viewing angle control component 110A limits the viewing angle range of the second display 11 in the second direction D2. For example, the multiple light shielding structures 1000B (see Figure 5A or Figure 5B ) can be arranged in sequence along the first direction D1 to limit the viewing angle range of the first display 10 in the first direction D1. The plurality of light shielding structures 1000B (see Figure 5A or Figure 5B) can be arranged in sequence along the second direction D2, for example, to limit the viewing angle range of the second display 11 in the second direction D2, but is not limited thereto. In other embodiments, the viewing angle control component 100 and the viewing angle control component 110A can limit the viewing angle in the same direction (e.g., the first direction D1, the second direction D2, or other directions) to different degrees, so that the viewing angle ranges of the first display 10 and the second display 11 are different. In other embodiments, although not shown, the first display 10 and the second display 11 can adopt the architecture of an edge-lit backlight module. In some embodiments, the design parameters or arrangement of the above-mentioned modulated light shielding structures 1000B of the viewing angle control component 100 and the viewing angle control component 110A can be different. In some embodiments, the viewing angle control component 110A can also include a first surface (not labeled) adjacent to the protective substrate 13 and a second surface (not labeled) opposite to the first surface (not labeled). In other words, the viewing angle control component 100A includes a first surface (not labeled) adjacent to the viewing side VS of the electronic device and a second surface (not labeled) opposite to the first surface (not labeled). The haze of the first surface (not labeled) may be greater than the haze of the second surface (not labeled). In some embodiments, the haze of the first surface (not labeled) may be less than or equal to 80%, and the haze of the second surface (not labeled) may be greater than 0 and less than or equal to 10%.

[0072] Please refer to Figure 3A as well as Figure 3B , the electronic device 1B and Figure 1A as well as Figure 1B The main difference between the electronic device 1 and the first display 10 is that the first display 10 and the second display 11 share the light source assembly 111 , the optical assembly 112 , the optical assembly 113 , the optical assembly 114 and / or the optical assembly 110 . Figure 1B The multiple grooves (including the groove G1 and the groove G2) of the back frame 12 are integrated into a single groove G, for example, and Figure 1BThe multiple platform portions (including platform portion P1 and platform portion P2) of the middle back frame 12 are integrated into a single platform portion P, which, for example, surrounds the groove G. The light source assembly 111 is positioned within the groove G and secured to the back frame 12 via an attachment AD6. The light source assembly 111 overlaps the first and second panels 105, 115 in the third direction D3. The optical assembly 112 is secured to a portion of the platform portion P via an attachment AD7. The optical assembly 112 overlaps the first and second panels 105, 115. The attachment AD7 is, for example, a patterned attachment, and is disposed on the platform portion P. In some embodiments, the width of the optical assembly 112 may be greater than the width of the light source assembly 111 in either the first or second direction D1, D2. The optical assembly 113 is optionally secured to the optical assembly 112 via a light-transmitting attachment AD10. In the third direction D3, the optical assembly 113 overlaps the first and second panels 105, 115. The optical component 114 is optionally fixed to the optical component 113 via a light-transmitting adhesive AD11, and in the third direction D3, the optical component 114 overlaps the first panel 105 and the second panel 115. The optical component 110 is optionally fixed to the optical component 114 via a light-transmitting adhesive AD12, and in the third direction D3, the optical component 110 overlaps the first panel 105 and the second panel 115. The viewing angle control component 100B is optionally fixed to the optical component 110 via a light-transmitting adhesive AD13. The viewing angle control component 100B may not include Figure 5A or Figure 5B The reflective polarizer 1003 and the transparent adhesive 1004 are also provided, but are not limited to such. The transparent adhesives AD10, AD11, AD12, and / or AD13 may comprise transparent organic or inorganic adhesives, such as, but not limited to, optically transparent adhesives or optically transparent resins. In some embodiments, in the third direction D3, the light source assembly 111, the optical assembly 112, the optical assembly 113, the optical assembly 114, and / or the optical assembly 110 may overlap the gap GS between the first panel 105 and the second panel 115.

[0073] In other embodiments, although not shown, the first display 10 and the second display 11 may adopt the architecture of the edge-type backlight module. In other embodiments, although not shown, the second display 11 may further include another viewing angle control component (such as Figure 2B The viewing angle control component 110A shown in FIG. Figure 3A as well as Figure 3B In the embodiment, the light source assembly 111 can be selectively driven in sections to provide light to the optical assembly or panel above (eg, the first panel 105 or the second panel 115) in sections.

[0074] Please refer to Figure 4Aas well as Figure 4B , the electronic device 1C and Figure 3A as well as Figure 3B The primary difference between the electronic device 1B and the electronic device 1B is that the transparent adhesive AD10, AD11, AD12, and / or AD13 are replaced with a patterned adhesive RT. The patterned adhesive RT is, for example, disposed on the viewing angle control component 100B and / or the optical component 110. The patterned adhesive RT secures the viewing angle control component 100B, the optical component 110, the optical component 114, the optical component 113, and / or the optical component 112 to the back frame 12. In some embodiments, the patterned adhesive RT secures the viewing angle control component 100B, the optical component 110, the optical component 114, the optical component 113, and / or the optical component 112 to the platform portion P of the back frame 12. In some embodiments, the patterned adhesive RT comprises a single-sided adhesive, such as, but not limited to, single-sided tape. In some embodiments, the patterned adhesive RT may have an annular shape when viewed from above (e.g., the third direction D3). This annular shape may, for example, roughly correspond to the outer shape of the back frame 12. In some embodiments (not shown), the patterned adhesive RT may, for example, include a plurality of sub-portions that are segmented from one another. In some embodiments, the patterned adhesive RT may, for example, extend along the inner wall surface 12-1 of the back frame 12 to between the adhesive AD5 and the back frame 12, but the present invention is not limited thereto. In some embodiments, the patterned adhesive RT may, for example, partially contact the inner wall surface 12-1 and / or the top surface 12-2 of the back frame 12, but the present invention is not limited thereto. The adhesive AD5 is, for example, disposed on the top surface 12-2 of the back frame 12, and the back frame 12 and the protective substrate 13 are fixed to each other via the adhesive AD5, but the present invention is not limited thereto. In some embodiments, the patterned adhesive RT includes a transparent adhesive, a non-transparent adhesive, or a combination thereof. In some embodiments, the patterned adhesive RT may, for example, contact portions of the viewing angle control component 100B and the optical component 110, and the patterned adhesive RT may, for example, contact portions of the side surface and top surface (the surface near the first panel 105) of the viewing angle control component 100B. In some embodiments, in the top-view direction (the third direction D3 ), the patterned adhesive RT may selectively not overlap with the active region R11 of the first panel 105 and the active region R21 of the second panel 115 .

[0075] In some embodiments, the shape of the electronic device can be circular, triangular, other polygonal or irregular shapes according to actual needs. Correspondingly, the components in the electronic device (such as the panel, viewing angle control component, optical component, light source component and / or back frame, etc.) also have corresponding shapes. Figure 6A as well as Figure 6BAs shown, the viewing angle control component LCF can be cut from a rectangle into a shape that is approximately circular. The cut viewing angle control component LCF can include alignment structures, such as alignment structure LCFa and / or at least one alignment structure LCFb. The cut viewing angle control component LCF, the first panel DP1, and the back frame BP can then be assembled together in sequence to form the electronic device 1D. The first panel DP1 can include a self-luminous display panel or a non-self-luminous display panel, and the first panel DP1 can include an active region R11 and an inactive region R12. Details of the active region R11 and the inactive region R12 can be found above and will not be repeated here. The viewing angle control component LCF includes at least one alignment structure (such as alignment structure LCFa and alignment structure LCFb). In a top-down view of the electronic device (such as the third direction D3), at least one alignment structure (such as alignment structure LCFa and alignment structure LCFb) overlaps the inactive region R12. The back frame BP can be used to support the first panel DP1 and the viewing angle control element LCF. The back frame BP includes at least one positioning structure (such as a positioning structure BPa and a positioning structure BPb) for fixing at least one alignment structure (such as an alignment structure LCFa and an alignment structure LCFb). The aforementioned component A overlaps the component B in the top view direction of the electronic device (the third direction D3), and the components A and B at least partially overlap.

[0076] The viewing angle control element LCF may include a first portion PP1 overlapping the active area R11 and a second portion PP2 overlapping the inactive area R12 in the top-view direction (third direction D3) of the electronic device, and the second portion PP2 includes an alignment structure LCFa and / or an alignment structure LCFb.

[0077] In some embodiments, at least one alignment structure may be a recess, a protrusion, or a through hole of the viewing angle control component LCF. Figure 6B As shown, the alignment structure LCFa is, for example, a protrusion of the second part PP2 of the viewing angle control component LCF, the alignment structure LCFb is, for example, a through hole of the second part PP2 of the viewing angle control component LCF, and the positioning structure BPa has, for example, a recessed portion that is substantially complementary to the shape of the alignment structure LCFa, and the positioning structure BPb has, for example, a columnar object that can pass through the through hole (alignment structure LCFb) of the viewing angle control component LCF, but is not limited to this. The shape of the top view contour of the through hole may not be limited. For example, the shape of the top view contour of the through hole may be circular, elliptical, rectangular or other shapes. As shown in FIG. Figure 6B As shown, alignment structures LCFb with different shapes are used to distinguish the front and back sides of the viewing angle control component LCF and / or the direction of the light shielding portion.

[0078] In some embodiments, the viewing angle control component LCF may be configured as Figure 5A or Figure 5BThe structure shown or the above-mentioned variation, and optionally omitting the reflective polarizer 1003 and / or the light-transmitting attachment 1004, but not limited thereto. The details of the viewing angle control component LCF can be referred to Figure 5A or Figure 5B The description will not be repeated here.

[0079] In some embodiments, as Figure 6B , the second part PP2 of the viewing angle control component LCF may include an alignment pattern LCFc, and the alignment pattern LCFc is formed, for example, by screen printing, yellow light etching process or other suitable processes. The material of the alignment pattern LCFc may include metal, ink, photoresist material, other suitable materials or a combination of the above. In addition, an alignment pattern DP1a corresponding to the alignment pattern LCFc can also be formed on the non-active area R12 of the first panel DP1 by screen printing or yellow light etching process. In this way, the viewing angle control component LCF and the first panel DP1 can be aligned through the alignment pattern LCFc and the alignment pattern DP1a, and the alignment pattern LCFc and the alignment pattern DP1a are aligned, for example, by manual alignment or photosensitive component alignment. In some embodiments, although not shown, the viewing angle control component LCF can be selectively fixed to the adjacent component or film layer by an adhesive (for example, a single-sided adhesive, a double-sided adhesive).

[0080] In some embodiments, as Figure 7A As shown, in addition to the viewing angle control component LCF, the first panel DP1 and the back frame BP, the electronic device 1E may also include a touch component TS and / or a protective substrate CV. The details of the touch component TS and the protective substrate CV can be referred to the above description and will not be repeated here. Figure 7A In the embodiment, the first panel DP1 comprises, for example, a self-luminous display panel, and the first panel DP1, the viewing angle control element LCF, the touch sensor element TS, and the protective substrate CV are sequentially disposed on the back frame BP, but the present invention is not limited thereto. In this embodiment, for example, the aforementioned light source element or at least some of the optical elements may be omitted. In other embodiments, although not shown, the viewing angle control element LCF may be disposed between the touch sensor element TS and the protective substrate CV.

[0081] In some embodiments, as Figure 7B As shown, in addition to the viewing angle control component LCF, the first panel DP1, the back frame BP, the touch component TS and the protection substrate CV, the electronic device 1E may also include a backlight module BL. The backlight module BL may include the aforementioned light source component 111, and the backlight module BL may be a direct-lit backlight module or an edge-lit backlight module. Figure 7BIn the embodiment, the first panel DP1 includes, for example, a non-self-luminous display panel, and the backlight module BL, the first panel DP1, the viewing angle control element LCF, the touch sensor assembly TS, and the protective substrate CV are, for example, sequentially disposed on the back bezel BP, but the present invention is not limited thereto. In other embodiments, although not shown, the viewing angle control element LCF may be disposed between the touch sensor assembly TS and the protective substrate CV, or between the backlight module BL and the first panel DP1.

[0082] In summary, in the embodiments of the present disclosure, by designing a first display including a viewing angle control assembly, an electronic device can provide a multi-screen display with varying viewing angles. In some embodiments, the viewing angle control assembly's alignment structure assists in aligning the viewing angle control assembly with the back frame and identifies the axial direction or front and back of the viewing angle control assembly. This facilitates alignment of the viewing angle control assembly for non-rectangular electronic devices, effectively improving viewing angle control effectiveness.
