Description

Technical Field

[0001] The present invention relates to a display module, and in particular to a display module with a viewing angle control device. Background Art

[0002] Electronic devices including display panels, such as tablet computers, notebook computers, smartphones, monitors and TVs, have become an indispensable necessity in modern society. With the booming development of such portable electronic products, consumers have high expectations for the quality, functions or prices of these products.

[0003] The functions of car audio and video systems are becoming increasingly rich. For safety reasons, the display system of the front passenger seat needs to have an anti-peep function when driving to reduce interference with driving. When not driving, it may be necessary to share information with the driver, so it needs to have a shared display function. The active anti-peep design can meet these two needs.

[0004] However, the junction of the anti-peeping display area and the shared display area is prone to produce abrupt visual effects due to obvious changes in brightness, affecting the visual taste, and easily causing overlapping images at side angles. Therefore, developing a display module that can further improve the display taste and performance is still one of the topics that the industry is currently committed to researching. Summary of the invention

[0005] According to some embodiments of the present invention, a display module is provided, comprising a display device, a first viewing angle control device and a second viewing angle control device, wherein the first viewing angle control device is adjacent to the display device, and the second viewing angle control device is disposed on the first viewing angle control device. The first viewing angle control device comprises a first substrate, a second substrate, a first liquid crystal layer and a first transparent conductive layer, wherein the first liquid crystal layer is disposed between the first substrate and the second substrate, and the first transparent conductive layer is disposed between the first substrate and the second substrate and comprises a first portion. The second viewing angle control device comprises a third substrate, a fourth substrate, a second liquid crystal layer and a second transparent conductive layer, wherein the second liquid crystal layer is disposed between the third substrate and the fourth substrate, and the second transparent conductive layer is disposed between the third substrate and the fourth substrate and comprises a second portion, and the second portion overlaps the first portion. In a cross-sectional view, the side edge of the first portion of the first transparent conductive layer is separated from the side edge of the second portion of the second transparent conductive layer by a first distance.

[0064] It should be understood that relative terms, such as "lower" or "bottom" or "upper" or "top", may be used in the embodiments to describe the relative relationship of one component to another component in the drawings. It is understood that if the device in the drawings is turned upside down, the component described on the "lower" side will become the component on the "upper" side. The embodiments of the present invention may be used in conjunction with the attached drawings. Figure 1 It is also understood that the drawings of the present invention are also considered as part of the disclosure. It should be understood that the drawings of the present invention are not drawn according to scale, and in fact, the size of the components may be arbitrarily enlarged or reduced to clearly show the features of the present invention.

[0065] Furthermore, when a first material layer is mentioned as being located on or above a second material layer, it may include a situation where the first material layer is in direct contact with the second material layer or the first material layer and the second material layer may not be in direct contact, that is, there may be one or more other material layers between the first material layer and the second material layer. However, if the first material layer is directly located on the second material layer, it means that the first material layer and the second material layer are in direct contact.

[0066] In addition, it should be understood that the ordinal numbers used in the specification and claims, such as "first", "second", etc., to modify components, do not imply or represent any previous ordinal numbers of the component (or components), nor do they represent the order of one component and another component, or the order of the manufacturing method. The use of these ordinal numbers is only used to make a component with a certain name clearly distinguishable from another component with the same name. The claims and the specification may not use the same words, for example, the first component in the specification may be the second component in the claims.

[0067] In some embodiments of the present invention, terms such as "connection", "interconnection", etc., related to bonding and connection, unless otherwise defined, may refer to two structures being in direct contact, or may also refer to two structures not being in direct contact, wherein another structure is disposed between the two structures. Such terms related to bonding and connection may also include situations where both structures are movable, or both structures are fixed. In addition, the terms "electrically connected" or "coupled" include any direct and indirect electrical connection means.

The term "range between a first value and a second value" means that the range includes the first value, the second value, and other values ​​therebetween. Furthermore, any two values ​​or directions used for comparison may have a certain error. If the first value is equal to the second value, it implies that there may be an error of about 10% between the first value and the second value; if the first direction is perpendicular to the second direction, the angle between the first direction and the second direction may be between 80 degrees and 100 degrees; if the first direction is parallel to the second direction, the angle between the first direction and the second direction may be between 0 degrees and 10 degrees.

[0069] Furthermore, according to embodiments of the present invention, an optical microscope (OM), a scanning electron microscope (SEM), an α-step, an ellipsometer, or other suitable methods may be used to measure the thickness, length, width, or distance and angle of each component. Specifically, according to some embodiments, a scanning electron microscope may be used to obtain a cross-sectional image of a structure and measure the thickness, length, width, or distance and angle of each component.

[0070] It should be understood that the following embodiments can replace, reorganize, and combine the features of several different embodiments to complete other embodiments without departing from the spirit of the present invention. The features of each embodiment can be combined and used in any combination as long as they do not violate the spirit of the invention or conflict with each other.

[0071] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meanings as commonly understood by those skilled in the art to which the present invention belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the background or context of the relevant technology and the present invention, and should not be interpreted in an idealized or overly formal manner unless specifically defined in the embodiments of the present invention.

[0072] According to an embodiment of the present invention, a display module is provided, comprising a display device and a viewing angle control device configured in a specific manner, which can be controlled by partitions to perform the same or different display modes (for example, a privacy mode and a share mode), meet the requirements of borderless display, reduce the sense of discontinuity of the picture at the junction of different display mode areas, improve the visual taste, and reduce the phenomenon of overlapping images caused by side viewing angles.

[0073] Please refer to Figure 1 , Figure 1 The cross-sectional structure diagram of the display module 10 is shown according to some embodiments of the present invention. It should be understood that, for the sake of clarity, some components of the display module 10 may be omitted in the drawings, and only some components are schematically illustrated. According to some embodiments, additional features may be added to the display module 10 described below. In addition, it should be understood that, in order to make the drawings clear and concise, the component symbols of some of the same components are only marked in the second viewing angle control device 200B, and are omitted in the first viewing angle control device 200A.

[0074] like Figure 1 As shown, the display module 10 may include a display device 100, a first viewing angle control device 200A and a second viewing angle control device 200B, the first viewing angle control device 200A may be adjacent to the display device 100, and the second viewing angle control device 200B may be disposed on the first viewing angle control device 200A. Furthermore, the display module 10 may further include a backlight device 300 adjacent to the first viewing angle control device 200A. According to some embodiments, the display module 10 may be a vehicle display module, but is not limited thereto.

[0075] The first viewing angle control device 200A and the second viewing angle control device 200B can be used to adjust the light output angle of the display module 10, so that the display module 10 can present a privacy mode and / or a share mode. According to some embodiments, the first viewing angle control device 200A can include a substrate 202a, a substrate 202b, a liquid crystal layer 210, and a transparent conductive layer 206a. Similarly, according to some embodiments, the second viewing angle control device 200B can include a substrate 202a, a substrate 202b, a liquid crystal layer 210, and a transparent conductive layer 206a.

[0076] According to some embodiments, the materials of the substrate 202a and the substrate 202b may include glass, quartz, sapphire, ceramic, polyimide (PI), polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), other suitable materials or combinations thereof, but are not limited thereto. Furthermore, the material of the substrate 202a may be the same as or different from the material of the substrate 202b.

[0077] The liquid crystal layer 210 may be disposed between the substrate 202a and the substrate 202b. According to some embodiments, the liquid crystal layer 210 may include nematic liquid crystal, smectic liquid crystal, cholesteric liquid crystal, blue-phase liquid crystal, other suitable liquid crystal materials or a combination thereof, but is not limited thereto.

[0078] The transparent conductive layer 206a may be disposed between the substrate 202a and the substrate 202b. For example, the transparent conductive layer 206a may be disposed on the substrate 202a. The transparent conductive layer 206a of the first viewing angle control device 200A may include a portion P1, and the transparent conductive layer 206a of the second viewing angle control device 200B may include a portion P2. In a cross-sectional view, a side edge 206s-1 of the portion P1 of the transparent conductive layer 206a of the first viewing angle control device 200A and a side edge 206s-2 of the portion P2 of the transparent conductive layer 206a of the second viewing angle control device 200B are separated by a distance S. According to some embodiments, the distance S may range from 1 millimeter (mm) to 50 mm (1 mm ≤ distance S ≤ 50 mm), or from 5 mm to 45 mm, for example, 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, or 40 mm.

[0079] According to some embodiments, the distance S refers to the maximum distance between the side edge 206s-1 and the side edge 206s-2 of the transparent conductive layer 206a in a direction perpendicular to the normal direction of the substrate 202a or the substrate 202b (eg, the X direction in the drawings).

[0080] It is worth noting that the transparent conductive layer 206a of the first viewing angle control device 200A and the second viewing angle control device 200B can be staggered so that the side 206s-1 and the side 206s-2 are separated by a distance S, thereby blurring the boundaries between different display areas (for example, the shared display area and the anti-peeping display area) of the display module 10, thereby improving the discontinuity of the picture at the boundaries.

[0081] As mentioned above, the transparent conductive layer 206a of the first viewing angle control device 200A and the second viewing angle control device 200B may include a portion P1 and a portion P2, respectively. In detail, according to some embodiments, the transparent conductive layer 206a of the first viewing angle control device 200A may be patterned to have a portion P1, a portion P3 adjacent to the portion P1, and a first gap SL1 between the portion P1 and the portion P3, and the transparent conductive layer 206a of the second viewing angle control device 200B may be patterned to have a portion P2, a portion P4 adjacent to the portion P2, and a second gap SL2 between the portion P2 and the portion P4. Moreover, in a top view, the first gap SL1 does not overlap with the second gap SL2. For example, in the normal direction of the substrate 202a or the substrate 202b (for example, the Z direction in the figure), the first gap SL1 does not overlap with the second gap SL2. Furthermore, the portion P2 may partially overlap with the portion P1, and the portion P4 may partially overlap with the portion P3. According to some embodiments, the width W1 of the first gap SL1 may be between 4 micrometers (μm) and 10 μm (4 μm ≤ width W1 ≤ 10 μm), for example, 5 μm, 6 μm, 7 μm, 8 μm, or 9 μm. According to some embodiments, the width W2 of the second gap SL2 may be between 4 μm and 10 μm (4 μm ≤ width W2 ≤ 10 μm), for example, 5 μm, 6 μm, 7 μm, 8 μm, or 9 μm.

[0082] According to some embodiments, the aforementioned width W1 refers to the maximum width of the first gap SL1 in a direction perpendicular to the normal direction of the substrate 202a or the substrate 202b (for example, the X direction in the figure). According to some embodiments, the aforementioned width W2 refers to the maximum width of the second gap SL2 in a direction perpendicular to the normal direction of the substrate 202a or the substrate 202b.

[0083] Furthermore, the portion P1 and the portion P3 of the transparent conductive layer 206a of the first viewing angle control device 200A may have a width Wa and a width Wb, respectively, and the portion P2 and the portion P4 of the transparent conductive layer 206a of the second viewing angle control device 200B may have a width Wc and a width Wd, respectively. According to some embodiments, the width Wa of the portion P1 may be greater than the width Wc of the portion P2 (width Wa>width Wc). According to some embodiments, the width Wb of the portion P3 may be less than the width Wd of the portion P4 (width Wb<width Wd).

[0084] According to some embodiments, the aforementioned width Wa, width Wb, width Wc and width Wd respectively refer to the maximum widths of portion P1, portion P3, portion P2 and portion P4 in a direction perpendicular to the normal direction of substrate 202a or substrate 202b (for example, the X direction in the drawings).

[0085] In addition, if Figure 1 As shown, according to some embodiments, the transparent conductive layer 206a may further include a portion PR, and the portion PR of the transparent conductive layer 206a may be disposed outside the spacer element 212, for example, may be disposed in a peripheral area (not shown) of the first viewing angle control device 200A and the first viewing angle control device 200B. According to some embodiments, the portion PR of the transparent conductive layer 206a may be further electrically connected to an external printed circuit board (PCB), a chip on film (COF) or a chip on glass (COG) structure, but is not limited thereto.

[0086] The material of the transparent conductive layer 206a may include a transparent conductive oxide (TCO). For example, according to some embodiments, the material of the transparent conductive layer 206a may include indium tin oxide (ITO), antimony zinc oxide (AZO), tin oxide (SnO), zinc oxide (ZnO), indium zinc oxide (IZO), indium gallium zinc oxide (IGZO), indium tin zinc oxide (ITZO), antimony tin oxide (ATO), other suitable transparent conductive materials, or a combination thereof, but not limited thereto.

[0087] In addition, according to some embodiments, the first viewing angle control device 200A and the second viewing angle control device 200B may further include a polarizing layer 201a, a polarizing layer 201b, an insulating layer 204a, an insulating layer 204b, a transparent conductive layer 206b, an alignment layer 208a, an alignment layer 208b, a spacer component 212, a spacer component 212m, a spacer component 212s, a conductive component 214 and a sealing component 216.

[0088] The polarizing layer 201a and the polarizing layer 201b can be respectively arranged on the outer surfaces of the substrate 202a and the substrate 202b. In detail, the polarizing layer 201a of the first viewing angle control device 200A can be arranged between the backlight device 300 and the substrate 202a, the polarizing layer 201b of the first viewing angle control device 200A can be arranged between the substrate 202b of the first viewing angle control device 200A and the substrate 202a of the second viewing angle control device 200B, and the polarizing layer 201b of the second viewing angle control device 200B can be arranged between the display device 100 and the substrate 202b.

[0089] According to some embodiments, the polarizing layer 201a and the polarizing layer 201b may include a poly vinyl alcohol (PVA) film. Furthermore, the polarizing layer 201a and the polarizing layer 201b may have a single-layer or multi-layer structure.

For example, the material of the aforementioned protective layer may include cyclo olefin polymer (COP), but is not limited thereto.

[0090] It should be understood that, according to some embodiments, the first viewing angle control device 200A and the second viewing angle control device 200B may have substantially the same structure and may share a polarizing layer 201b (eg, Figure 1As shown, the polarizing layer 201b of the first viewing angle control device 200A can be used by the second viewing angle control device 200B). However, according to other embodiments, the second viewing angle control device 200B may further include a polarizing layer (not shown) disposed between the substrate 202a and the polarizing layer 201b of the first viewing angle control device 200A. In addition, according to some other embodiments, the backlight module 300 may have a reflective brightness enhancement film (DBEF) disposed on the top surface, so the first viewing angle control device 200A may omit the polarizing layer 201a adjacent to the backlight module 300.

[0091] The insulating layer 204a may be disposed between the substrate 202a and the transparent conductive layer 206a, and the insulating layer 204b may be disposed between the substrate 202b and the transparent conductive layer 206b.

According to some embodiments, the gamma correction integrated circuit component 240 may be electrically connected to the data line driving component 220 to control the color temperature of the display device 100. Furthermore, according to some embodiments, the timing controller 280 may be electrically connected to the gate line driving component 260 to control the timing of the display device 100.

[0109] Next, please refer to Figure 4A as well as Figure 4B , Figure 4A as well as Figure 4B A schematic diagram showing a display device 100 in a display module according to some embodiments of the present invention is shown. It should be understood that Figure 4A as well as Figure 4B It is a simple schematic diagram of the screen of the display device 100 viewed by the user.

[0110] As mentioned above, the first viewing angle control device 200A and the second viewing angle control device 200B can adjust the light emission angle of the display module 10 so that the display module 10 can present an anti-peeping mode and / or a sharing mode. Figure 4A As shown, according to some embodiments, the display device 100 may have a shared display area AS and an anti-peeping display area AP, and the display device 100 has an interface area AI between the shared display area AS and the anti-peeping display area AP, and the interface area AI includes a mark (icon) O1. Furthermore, according to some embodiments, the interface area AI between the shared display area AS and the anti-peeping display area AP substantially corresponds to the area of ​​the first gap SL1 or the second gap SL2. In other words, the area where the display device 100 overlaps with the first gap SL1 or the second gap SL2 may include the mark O1. According to some embodiments, the mark O1 may be at a distance S (such as Figure 1 shown) overlap.

[0111] like Figure 4BAs shown, according to some embodiments, the display device 100 may have a shared display area AS and an anti-peeping display area AP, and the display device 100 includes a logo O2 in the boundary area AI between the shared display area AS and the anti-peeping display area AP. Furthermore, according to some embodiments, the boundary area AI between the display area AS and the anti-peeping display area AP substantially corresponds to the area of ​​the first gap SL1 or the second gap SL2. In other words, the area where the display device 100 overlaps with the first gap SL1 or the second gap SL2 may include the logo O2. According to some embodiments, the logo O2 may be at a distance S (such as Figure 1 shown) overlap.

[0112] It is worth noting that the setting of the mark O1 or the mark O2 can be used to modify the junction of different display areas (for example, the shared display area AS and the anti-peeping display area AP) of the display device 100 to improve the sense of picture discontinuity at the junction.

[0113] Next, please refer to Figure 5 , Figure 5 A schematic diagram of a display device 100 in a display module according to some other embodiments of the present invention is shown. It should be understood that: Figure 5 It is a simple schematic diagram of the screen of the display device 100 viewed by the user.

[0114] like Figure 5 As shown, when the display device 100 has a shared display area AS and an anti-peeping display area AP, there is an interface area AI between the shared display area AS and the anti-peeping display area AP, and the brightness of the interface area AI may be lower than the brightness of the shared display area AS and / or the anti-peeping display area AP. In detail, according to some embodiments, the backlight device 300 of the display module may have an integrated circuit (IC) component (not shown), and the brightness of the interface area AI may be controlled by the integrated circuit component to make it lower than the brightness of the shared display area AS and / or the anti-peeping display area AP. Alternatively, according to some embodiments, the signal provided to the display device 100 may be processed by image processing software to achieve the effect of rendering the image of the interface area AI, thereby making the brightness of the interface area AI lower than the brightness of the shared display area AS and / or the anti-peeping display area AP.

[0115] Furthermore, according to some other embodiments, when the display device 100 has a shared display area AS and an anti-peeping display area AP, the color temperature of the interface area AI is different from the color temperature of the shared display area AS and / or the anti-peeping display area AP. In detail, according to some embodiments, the display device 100 of the display module has a gamma correction integrated circuit (Gamma IC) component 240, and the color temperature of the interface area AI can be controlled by the gamma correction integrated circuit component 240 (for example, color temperature complementary rendering). Alternatively, according to some embodiments, the signal provided to the display device 100 can also be processed by image processing software to achieve the effect of rendering the image of the interface area AI, thereby making the color temperature of the interface area AI different from the color temperature of the shared display area AS and / or the anti-peeping display area AP, reducing the poor optical taste of the display module 10 due to the color deviation of the large viewing angle, and optimizing the optical taste of the display module 10. Color temperature complementary rendering is not limited to the intersection AI. In other embodiments, the surrounding areas of the shared display area AS and / or the anti-peeping display area AP may also be rendered with complementary color temperatures. In other words, the color temperature of the surrounding areas of the shared display area AS is different from the color temperature of the middle area. Similarly, the color temperature of the surrounding areas of the anti-peeping display area AP may also be different from the color temperature of the middle area, but is not limited to this.

[0116] It is worth noting that the brightness and / or color temperature of the boundary area AI can be adjusted by any combination of the above methods to achieve the effect of blurring the boundaries between different display areas of the display device 100 and improve the discontinuity of the image at the boundaries.

[0117] In addition, according to some embodiments, the display module may further include a sensing device (not shown), which may be coupled to the first viewing angle control device 200A and the second viewing angle control device 200B, and the sensing device may control the display device 100 so that it has a shared display area AS and / or an anti-peeping display area AP. In detail, the switching of the shared display area AS and the anti-peeping display area AP may be automatically controlled by a sensing device such as a vehicle speed sensor, a charge coupled device (CCD) or a visual sensor of the vehicle computer. According to some embodiments, the user may also directly control the screen. According to some embodiments, the display module may further include a vehicle control unit (VCU) (not shown), which is coupled to the sensing device, that is, the switching of the shared display area AS and the anti-peeping display area AP may be controlled by the vehicle controller.

[0118] Next, please refer to Figure 6 , Figure 6 The schematic diagram of the display device 100 in the display module according to some other embodiments of the present invention is shown. It should be understood that Figure 6 It is a simple schematic diagram of the screen of the display device 100 viewed by the user.

[0119] According to some embodiments, the display device 100 of the display module may have a touch function, for example, further include touch electrodes, so that the sizes of the shared display area AS and the anti-peeping display area AP may be adjusted by pressing the touch.

[0120] Next, please refer to Figure 7 , Figure 7 A schematic diagram of the structure of some components in a display module according to some embodiments of the present invention is shown. Specifically, for the sake of clarity, Figure 7 Only the display device 100 of the display module and the transparent conductive layer 206 a of the first viewing angle control device 200A or the second viewing angle control device 200B are shown.

[0121] like Figure 7 As shown, according to some embodiments, the display device 100 may have a plurality of first pixel units PX1, a plurality of second pixel units PX2, and a plurality of third pixel units PX3 that emit light of different colors. The first pixel unit PX1, the second pixel unit PX2, and the third pixel unit PX3 may be arranged in a longitudinal strip manner. For example, the first pixel unit PX1, the second pixel unit PX2, and the third pixel unit PX3 are arranged in a direction DS-1 (for example, the X direction in the drawings) perpendicular to the length direction D206 of the transparent conductive layer 206a (for example, the Y direction in the drawings). Furthermore, the side 206s-1 of the portion P1 and / or the side 206s-2 of the portion P2 of the transparent conductive layer 206a may be non-linear. For example, as Figure 7 As shown, according to some embodiments, the side edge 206s-1 of the portion P1 or the side edge 206s-2 of the portion P2 of the transparent conductive layer 206a may be serrated, but is not limited thereto. According to some embodiments, the side edge 206s-1 of the portion P1 or the side edge 206s-2 of the portion P2 of the transparent conductive layer 206a may be arc-shaped, irregular or other suitable non-linear shapes. It is worth noting that, through such a configuration, it is possible to reduce the large-area appearance of single-color pixel units at the junction of different display areas of the display device 100, reduce the generation of color stripes at the junction, and thus improve the discontinuity of the picture at the junction.

[0122] It should be understood that, according to some embodiments, the term "length direction" may be defined as a direction along or parallel to the long axis of an object. The long axis is defined as a straight line extending lengthwise through the center of an object. For an elongated or elliptical object, the long axis is closest to its maximum longitudinal dimension. For an object without a clear long axis, the long axis may represent the long axis of the smallest rectangle that can surround the object.

[0123] Furthermore, it should be understood that the embodiment shown in the accompanying drawings is described by taking the display device 100 having three pixel units (first pixel unit PX1, second pixel unit PX2 and third pixel unit PX3) as an example. According to some embodiments, the first pixel unit PX1, the second pixel unit PX2 and the third pixel unit PX3 may be a red pixel unit, a green pixel unit and a blue pixel unit, respectively. However, according to different embodiments, the display device 100 may have other suitable numbers and colors of pixel units, and the present invention is not limited thereto.

[0124] Next, please refer to Figure 8 , Figure 8 Shown are structural diagrams of some components in a display module according to other embodiments of the present invention. Specifically, for the sake of clarity, Figure 8 Only the display device 100 of the display module and the transparent conductive layer 206 a of the first viewing angle control device 200A or the second viewing angle control device 200B are shown.

[0125] like Figure 8 As shown, according to some embodiments, the first pixel unit PX1, the second pixel unit PX2 and the third pixel unit PX3 are arranged in a sub-pixel rendering (SPR) manner, that is, the pixel units of the same color are not arranged continuously. In this embodiment, the side 206s-1 of the portion P1 or the side 206s-2 of the portion P2 of the transparent conductive layer 206a may be linear (e.g. Figure 8 Through this configuration, it is also possible to reduce the large-area appearance of single-color pixel units at the junction of different display areas of the display device 100, reduce the generation of color stripes at the junction, and thus improve the discontinuity of the picture at the junction.

[0126] Next, please refer to Fig. 9 , Fig. 9 Shown are structural diagrams of some components in a display module according to other embodiments of the present invention. Specifically, for the sake of clarity, Fig. 9 Only the display device 100 of the display module and the transparent conductive layer 206 a of the first viewing angle control device 200A or the second viewing angle control device 200B are shown.

[0127] like Fig. 9As shown, according to some embodiments, the first pixel unit PX1, the second pixel unit PX2 and the third pixel unit PX3 can be arranged in a horizontal strip manner, for example, the first pixel unit PX1, the second pixel unit PX2 and the third pixel unit PX3 are arranged in a direction DS-2 parallel to the length direction D206 of the transparent conductive layer 206a (for example, the Y direction in the figure). In this embodiment, the side 206s-1 of the portion P1 or the side 206s-2 of the portion P2 of the transparent conductive layer 206a can be linear (such as Fig. 9 Through this configuration, it is also possible to reduce the large-area appearance of single-color pixel units at the junction of different display areas of the display device 100, reduce the generation of color stripes at the junction, and thus improve the discontinuity of the picture at the junction.

[0128] Next, please refer to Fig.10 , Fig.10 Shown are structural diagrams of some components in a display module according to other embodiments of the present invention. Specifically, for the sake of clarity, Fig.10 Only the display device 100 of the display module and the transparent conductive layer 206 a (labeled as 206 a - 1 and 206 a - 2 , respectively, for the convenience of description) of the first viewing angle control device 200A and the second viewing angle control device 200B are illustrated.

[0129] like Fig.10 As shown, according to some embodiments, the side edge 206s-1 of the transparent conductive layer 206a-1 of the first viewing angle control device 200A and the side edge 206s-2 of the transparent conductive layer 206a-2 of the second viewing angle control device 200B may both be non-linear, and the transparent conductive layer 206a-1 and the transparent conductive layer 206a-2 may be staggered so that the side edge 206s-1 and the side edge 206s-2 are separated by a distance S. Furthermore, the side edge 206s-1 of the transparent conductive layer 206a-1 may have a protrusion R1 (e.g., a sawtooth protrusion), and the protrusion R1 may have an angle θA, and the side edge 206s-2 of the transparent conductive layer 206a-2 may have a protrusion R2 (e.g., a sawtooth protrusion), and the protrusion R2 may have an angle θB, and the angle θA is substantially equal to the angle θB. This configuration can reduce the large-area appearance of single-color pixel units at the junction of different display areas of the display device 100, reduce the generation of color patterns and overlapping images at the junction, and thus improve the discontinuity of the image at the junction.

[0130] Please refer to Fig.11 , Fig.10 Shown are structural diagrams of some components in a display module according to other embodiments of the present invention. Specifically, for the sake of clarity, Fig.11Only the display device 100 of the display module and the transparent conductive layer 206 a (labeled as 206 a - 1 and 206 a - 2 , respectively, for the convenience of description) of the first viewing angle control device 200A and the second viewing angle control device 200B are illustrated.

[0131] like Fig.11 As shown, according to some embodiments, the side edge 206s-1 of the transparent conductive layer 206a-1 of the first viewing angle control device 200A and the side edge 206s-2 of the transparent conductive layer 206a-2 of the second viewing angle control device 200B may both be non-linear, and the transparent conductive layer 206a-1 and the transparent conductive layer 206a-2 may be staggered so that the side edge 206s-1 and the side edge 206s-2 are separated by a distance S. Furthermore, in this embodiment, the side edge 206s-1 of the transparent conductive layer 206a-1 and the side edge 206s-2 of the transparent conductive layer 206a-2 may have different shapes. Specifically, the protrusion R1 of the side 206s-1 of the transparent conductive layer 206a-1 may have an angle θA, and the protrusion R2 of the side 206s-2 of the transparent conductive layer 206a-2 may have an angle θB, and the angle θA is different from the angle θB, for example, the angle θA may be greater than the angle θB. Through this configuration, it is possible to reduce the large-area appearance of single-color pixel units at the junction of different display areas of the display device 100, reduce the generation of color patterns and overlapping images at the junction, and thus improve the discontinuity of the picture at the junction.

[0132] Next, please refer to Fig.12 , Fig.12 A schematic diagram showing a light incident on a viewing angle control device in a display module in some embodiments of the present invention. Specifically, Fig.12 The diagram shows the refraction of the light L in the first viewing angle control device 200A and the second viewing angle control device 200B of the display module 10. It should be understood that for the sake of clarity, Fig.12 Only the first viewing angle control device 200A, the second viewing angle control device 200B and the polarizing layers 201 a and 201 b included therein are illustrated, and the oblique lines in the drawings represent the area of ​​the anti-peeping display mode.

[0133] like Fig.12 As shown, according to some embodiments, the light L enters the second viewing angle control device 200B at an incident angle θ1 and generates a refraction angle θ2. The second viewing angle control device 200B has a thickness d. In this case, the side edge 206s-1 (eg, Figure 1 ) and the side edge 206s-2 of the portion P2 (as shown Figure 1According to some embodiments, the incident angle θ1 may be between 30 degrees and 65 degrees (30 degrees ≤ incident angle θ1 ≤ 65 degrees), for example, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees or 60 degrees, but not limited thereto. According to some embodiments, the refraction angle θ2 may be the refraction angle generated when the light L is incident from air (refractive index n is 1) to glass (refractive index n is about 1.5). The aforementioned incident angle θ1 and refraction angle θ2 are both angles relative to the normal direction of the substrate 202a or the substrate 202b (for example, the Z direction in the accompanying drawings). Furthermore, the thickness d of the second viewing angle control device 200B may be defined as the distance between the polarizing layer 201b of the second viewing angle control device 200B and the polarizing layer 201b of the first viewing angle control device 200A in the normal direction of the substrate 202a or the substrate 202b (for example, the Z direction in the accompanying drawings). As mentioned above, according to some embodiments, the distance S may range from 1 mm to 50 mm (1 mm ≤ distance S ≤ 50 mm), or from 5 mm to 45 mm, such as 10 mm, 15 mm, 20 mm, 25 mm, 30 mm, 35 mm or 40 mm. In some embodiments, the distance S may be Tan(θ2)×d±25 mm, Tan(θ2)×d±20 mm, Tan(θ2)×d±10 mm, so as to reduce light leakage or overlapping caused by errors, which may reduce the optical quality of the display module.

[0134] Next, please refer to Fig.13 , Fig.13 A schematic diagram of a display module is shown according to some embodiments of the present invention. It should be understood that Fig.13 It is only used to illustrate the alignment method between the display device 100, the first viewing angle control device 200A and the second viewing angle control device 200B, and does not represent the actual positional relationship between these components.

[0135] like Fig.13As shown, the display device 100 may have a display area DA and a peripheral area PA surrounding the display area DA, and the display device 100 may include a first alignment mark M1 disposed in the peripheral area PA. The first viewing angle control device 200A may have a viewing angle adjustment area JA and a peripheral area PA surrounding the viewing angle adjustment area JA, and the first viewing angle control device 200A may include a second alignment mark M2 disposed in the peripheral area PA. Furthermore, the second viewing angle control device 200B may have a viewing angle adjustment area JA and a peripheral area PA surrounding the viewing angle adjustment area JA, and the second viewing angle control device 200B may include a third alignment mark M3 disposed in the peripheral area PA. According to some embodiments, the viewing angle adjustment area JA of the second viewing angle control device 200B may substantially correspond to the display area DA of the display device 100. According to some embodiments, the transparent conductive layer 206a of the first viewing angle control device 200A and the second viewing angle control device 200B are not misaligned (i.e., the side 206s-1 and the side 206s-2 are substantially overlapped). In this case, the first alignment mark M1 of the display device 100 may overlap with the third alignment mark M3 of the second viewing angle control device 200B, and the second alignment mark M2 of the first viewing angle control device 200A may be separated from the third alignment mark M3 of the second viewing angle control device 200B by a distance S', and the distance S' is the same as the misaligned distance S between the side 206s-1 and the side 206s-2 of the transparent conductive layer 206a (e.g., Figure 1 In other words, according to some embodiments, the transparent conductive layer 206a of the first viewing angle control device 200A and the second viewing angle control device 200B of the display module is not staggered, but the first viewing angle control device 200A and the second viewing angle control device 200B are staggered so that the side edge 206s-1 and the side edge 206s-2 of the transparent conductive layer 206a are separated by a distance S.

[0136] However, according to some embodiments, the transparent conductive layer 206a of the first viewing angle control device 200A and the second viewing angle control device 200B of the display module are already staggered (eg, Figure 1 As shown), the side 206s-1 and the side 206s-2 of the transparent conductive layer 206a are separated by a distance S. In this case, the first alignment mark M1 of the display device 100, the third alignment mark M3 of the second viewing angle control device 200B, and the second alignment mark M2 of the first viewing angle control device 200A can be overlapped to complete the alignment.

[0137] In summary, according to an embodiment of the present invention, a display module is provided, which includes a display device and a viewing angle control device configured in a specific manner, and can be controlled in partitions to perform the same or different modes of display (for example, anti-peep mode and / or sharing mode), thereby achieving borderless requirements, and can reduce the sense of discontinuity of the picture at the junction of different display mode areas, improve visual taste, and reduce the phenomenon of overlapping images caused by side viewing angles.
