[0059] The following is a detailed description of the display device of the embodiment of the present disclosure. It should be understood that the following description provides many different embodiments for implementing different aspects of some embodiments of the present disclosure. The specific components and arrangements described below are only for 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 the purpose of simply and clearly describing some embodiments of the present disclosure, and does not represent any correlation between the different embodiments and / or structures discussed.
[0060] The present disclosure can be understood by referring to the following detailed description in conjunction with the accompanying drawings. It should be noted that in order to facilitate the understanding of the readers and the simplicity of the drawings, the multiple drawings in the present disclosure only depict a portion of the electronic device, and the specific components in the drawings are not drawn according to the actual scale. In addition, the number and size of each component in the drawings are only for illustration and are not intended to limit the scope of the present disclosure.
[0061] It should be understood that the components or devices of the drawings may exist in various forms known to those skilled in the art. In addition, 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 of the drawings to another component. It is understood that if the device of the drawings is turned upside down, the component described on the "lower" side will become the component on the "higher" side. The embodiments of the present disclosure may be used in conjunction with the attached drawings. Figure 1It is also understood that the drawings of the present disclosure are also considered as part of the disclosure. Furthermore, when a first material layer is mentioned as being located on or above a second material layer, it includes the situation where the first material layer is in direct contact with the second material layer, or there may be one or more other material layers in between, in which case the first material layer and the second material layer may not be in direct contact.
[0062] Certain words are used throughout the specification and the claims that follow to refer to specific components. It should be understood by those skilled in the art that electronic equipment manufacturers may refer to the same components by different names. This document does not intend to distinguish between components that have the same function but different names. In the following specification and claims, words such as "include", "contain", "have" are open-ended words, and therefore should be interpreted as "including but not limited to..." Therefore, when the terms "include", "contain" and / or "have" are used in the description of the present disclosure, they specify the existence of corresponding features, areas, steps, operations and / or components, but do not exclude the existence of one or more corresponding features, areas, steps, operations and / or components.
[0063] The directional terms mentioned herein, such as "up", "down", "front", "back", "left", "right", etc., are only references to the directions of the accompanying drawings. Therefore, the directional terms used are for illustration and not for limiting the present disclosure. In the accompanying drawings, each figure shows the general characteristics of the methods, structures and / or materials used in a particular embodiment. However, these drawings should not be interpreted as defining or limiting the scope or nature covered by these embodiments. For example, for clarity, the relative size, thickness and position of each film layer, region and / or structure may be reduced or enlarged.
[0064] When a corresponding component (such as a film layer or region) is referred to as being "on another component", it can be directly on the other component, or other components can exist between the two. On the other hand, when a component is referred to as being "directly on another component", there is no component between the two. In addition, when a component is referred to as being "on another component", the two have a top-down relationship in the top view direction, and the component can be above or below the other component, and this top-down relationship depends on the orientation of the device.
[0065] According to some embodiments of the present disclosure, 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 "electrically coupled" include any direct and indirect electrical connection means.
[0066] In addition, it should be understood that although the terms "first", "second", "third", etc. may be used herein to describe various components, assemblies, or parts, these components, assemblies, or parts should not be limited by these terms. These terms are only used to distinguish different components, assemblies, regions, layers, or parts. Therefore, a first component, component, region, layer, or part discussed below may be referred to as a second component, component, region, layer, or part without departing from the teachings of the present disclosure.
[0067] In the text, the terms "about" and "substantially" usually mean within 10%, within 5%, within 3%, within 2%, within 1%, or within 0.5% of a given value or range. The numbers given here are approximate numbers, that is, in the absence of specific description of "about" and "substantially", the meaning of "about" and "substantially" can still be implied. In addition, 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 between them.
[0068] It should be understood that the following embodiments may replace, reorganize, or mix features in several different embodiments to complete other embodiments without departing from the spirit of the present disclosure. Features between embodiments may be mixed and matched as long as they do not violate the spirit of the invention or conflict with each other.
[0069] In the present disclosure, the thickness, length and width can be measured by an optical microscope, and the thickness can be measured by a cross-sectional image in an electron microscope, but it is not limited to this. In addition, 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 -10 degrees and 10 degrees.
[0070] 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 disclosure 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 disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined in the embodiments of the present disclosure.

In addition, the thin-film transistor may be a top gate thin-film transistor, a bottom gate thin-film transistor, or a dual gate or double gate thin-film transistor. Figure 2BAs shown, according to some embodiments, the switch unit 300 may include at least one semiconductor layer 300s, a gate electrode (not shown, such as a portion of the scan line SL), a source electrode, and a drain electrode (not shown). In the normal direction of the substrate 100a (such as the Z direction in the figure), the source electrode, the drain electrode, and the gate electrode at least partially overlap with the semiconductor layer 300s. According to some embodiments, the patterned electrode 130 may be electrically connected to the drain electrode or the source electrode of the switch unit 300 through the electrode through-hole 130v.

[0088] Furthermore, if Figure 2B As shown, according to some embodiments, the patterned electrode 130 has a main body 130m and a sub-part 130p. According to some embodiments, the sub-part 130p includes a sub-part P1, a sub-part P2, a sub-part P3, and a sub-part P4. Specifically, the main body 130m can divide the patterned electrode 130 into sub-part P1, sub-part P2, sub-part P3, and sub-part P4, wherein the sub-part P1, sub-part P2, sub-part P3, and sub-part P4 can be arranged in a counter-clockwise manner.

Under the condition that the liquid crystal layer 110 is doped with a left-handed chiral agent, and when the absorption axis of the polarizer 120a is approximately perpendicular to the absorption axis of the polarizer 120b, the aforementioned first angle θ1 may be greater than or equal to 20 degrees and less than or equal to 90 degrees. For another example, the multiple branches 130t in the sub-portion P1 extend generally in the extension direction D2. The aforementioned extension direction D2 may be the direction in which the center line CL of the main portion 130m is rotated clockwise by an angle (e.g., the second angle θ2). In some embodiments, please refer to Figure 1 and Figure 2B , the second angle θ2 may also be the angle between the branch portion 130t and the main portion 130m in the sub-portion P1. Under the condition that the liquid crystal layer 110 is doped with a left-handed chiral agent, and when the absorption axis of the polarizing plate 120a is substantially perpendicular to the absorption axis of the polarizing plate 120b, the second angle θ2 may be greater than or equal to 5 degrees and less than or equal to 60 degrees. In one embodiment, under the condition that the liquid crystal layer 110 is doped with a left-handed chiral agent, and when the absorption axis of the polarizing plate 120a is substantially perpendicular to the absorption axis of the polarizing plate 120b, the first angle θ1 may be substantially equal to 70 degrees, and the second angle θ2 may be substantially equal to 20 degrees.
[0090] In addition, according to some embodiments, the first angle θ1 is not equal to the second angle θ2. According to some embodiments, the branch portion 130t in the sub-portion P3 may have a third angle (not shown) with the main body 130m, and the branch portion 130t in the sub-portion P4 may have a fourth angle (not shown) with the main body 130m. According to some embodiments, the third angle is not equal to the fourth angle. In addition, the definitions of the third angle and the fourth angle are similar to the definitions of the first angle θ1 and the second angle θ2, and are not repeated here.
[0091] According to some embodiments, the edges of the sub-portion P1, the sub-portion P2, the sub-portion P3, and the sub-portion P4 arranged counterclockwise may be defined in sequence as a first edge e1, a second edge e2, a third edge e3, a fourth edge e4, a fifth edge e5, a sixth edge e6, a seventh edge e7, and an eighth edge e8. The first edge e1, the second edge e2, the third edge e3, the fourth edge e4, the fifth edge e5, the sixth edge e6, the seventh edge e7, and the eighth edge e8 are also arranged counterclockwise.
[0092] It is worth noting that Figure 2B As shown, according to some embodiments, the edge E130 of the patterned electrode 130 closest to the switch unit 300 (i.e., the sixth edge e6 and the seventh edge e7) has an open area OP and a closed area CP, the open area OP is adjacent to the closed area CP, and the patterned electrode 130 extends a connection portion 130x from the closed area CP to be electrically connected to the switch unit 300 through the electrode through-hole 130v. According to some embodiments, the open area OP and the closed area CP are respectively located on both sides of the center line CL of the main body 130m. In some embodiments, the open area OP can be defined as a region where the sixth edge e6 extends a distance along the positive Y direction and the negative Y direction, respectively, and this distance can be substantially equal to 5 microns. Similarly, the closed area CP can be defined as a region where the seventh edge e7 extends a distance along the positive Y direction and the negative Y direction, respectively, and this distance can be substantially equal to 5 microns. In other words, the open area OP substantially corresponds to the sixth edge e6 defined above, and the closed area CP substantially corresponds to the seventh edge e7 defined above. According to some embodiments, the connection portion 130 x is a contact point connecting the patterned electrode 130 and the switch unit 300 , and the material of the connection portion 130 x may be the same as that of the patterned electrode 130 , but is not limited thereto.
[0093] like Figure 2B As shown, according to some embodiments, the second edge e2 of the sub-portion P1 or the third edge e3 of the sub-portion P2 may also have an open area OP, but is not limited thereto. According to some embodiments, the patterned electrode 130 having the open area OP may improve the arrangement stability of the liquid crystal.
[0094] Furthermore, according to some embodiments, the connection portion 130x may extend from any position of the closed area CP (the seventh edge e7) toward the switch unit 300, and be electrically connected to the switch unit 300 through the electrode through-hole 130v. According to some embodiments, in the normal direction of the substrate 100a (e.g., the Z direction in the figure), a portion of at least one of the branch portions 130t may be located in the open area OP. According to some embodiments, in the normal direction of the substrate 100a (e.g., the Z direction in the figure), a portion of at least one of the branch portions 130t may be located in the closed area CP.
[0095] According to some embodiments, the portion of the connection portion 130x in contact with the patterned electrode 130 may extend along a first direction, and the portion of the connection portion 130x in contact with the electrode through-hole 130v may extend along a second direction, and the first direction may be different from the second direction, for example, the first direction may be substantially perpendicular to the second direction. According to some embodiments, the first direction may be substantially parallel to the data line DL, and the second direction may be substantially parallel to the scan line SL.
[0096] According to some embodiments, the connection portion 130x may have a width W1, and the width W1 may be between 1 micrometer (μm) and 12 micrometers (i.e., 1 μm≤width W1≤12 μm), or between 2 micrometers and 8 micrometers. For example, the width W1 may be substantially equal to 6 micrometers, but the present disclosure is not limited thereto. According to some embodiments, the aforementioned width W1 refers to the minimum width of the connection portion 130x in a direction perpendicular to its extension direction.
[0097] In addition, according to the embodiments of the present disclosure, an optical microscope (OM), a scanning electron microscope (SEM), an α-step, an ellipsometer, or other suitable methods may be used to measure the width, length, thickness, or distance between components of each component. Specifically, according to some embodiments, a scanning electron microscope may be used to obtain any cross-sectional image of a structure, and the width, length, thickness, or distance between components of each component in the image may be measured.
[0098] It is worth noting that according to the embodiment of the present disclosure, the connecting portion 130x connecting the patterned electrode 130 and the switching unit 300 can be set at a specific position of the patterned electrode 130 (for example, on a specific edge of the patterned electrode 130), thereby improving the liquid crystal arrangement stability of the display device 10 or reducing the problem of afterimages generated when the panel 10A is scratched by external force.
[0099] Specifically, according to some embodiments, when the liquid crystal layer 110 is doped with a left-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100a, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at any position on the odd-numbered edges (e.g., the seventh edge e7) of the patterned electrode 130. According to other embodiments, when the liquid crystal layer 110 is doped with a left-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100b, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at any position on the even-numbered edges (e.g., the sixth edge e6) of the patterned electrode 130.
[0100] According to some embodiments, when the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100a, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at any position on the even-numbered edge (e.g., the sixth edge e6) of the patterned electrode 130. According to other embodiments, when the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100b, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at any position on the odd-numbered edge (e.g., the seventh edge e7) of the patterned electrode 130. In other words, when the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on a substrate closer to the backlight module 10B, the connection portion 130x can be disposed at any position on the even-numbered edges (e.g., the sixth edge e6) of the patterned electrode 130. Conversely, when the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on a substrate farther from the backlight module 10B, the connection portion 130x can be disposed at any position on the odd-numbered edges (e.g., the seventh edge e7) of the patterned electrode 130.
[0101] Next, please refer to Figure 3 , Figure 3 A partial top view of the structure of the display device 10 is shown according to some other embodiments of the present disclosure. Specifically, Figure 3 The configuration relationship between the patterned electrode 130 and the adjacent driving components of the display device 10 is shown. It should be understood that the same or similar components or components as those in the previous text will be represented by the same or similar reference numerals, and their materials, manufacturing methods and functions are the same or similar to those described in the previous text, so this part will not be repeated in the following text.
[0102] like Figure 3 As shown, according to some embodiments, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed in the open area OP. Specifically, according to some embodiments, the patterned electrode 130 has an end TR, and the end TR is located at the open area OP farther away from the closed area CP, and the patterned electrode 130 may extend a connection portion 130x from the end TR, and the connection portion 130x is electrically connected to the switch unit 300 through the electrode through-hole 130v. According to some embodiments, the end TR may be the portion of the branch portion 130t in the open area OP that is farthest away from the closed area CP. According to some embodiments, in the normal direction of the substrate 100a (e.g., the Z direction in the figure), the end TR may overlap with the intersection of the fifth edge e5 and the sixth edge e6. According to some embodiments, the end TR may be regarded as the corner point of the sixth edge e6.
[0103] According to some embodiments, the connection portion 130x may extend from the end portion TR toward the electrode through-hole 130v. According to some embodiments, the portion of the connection portion 130x in contact with the patterned electrode 130 may extend along a first direction, and the portion of the connection portion 130x in contact with the electrode through-hole 130v may extend along a second direction, and the first direction may be different from the second direction, for example, the first direction may be substantially perpendicular to the second direction. According to some embodiments, the first direction may be substantially parallel to the data line DL, and the second direction may be substantially parallel to the scan line SL.
[0104] According to some embodiments, the end TR may have a width W2, and the width W2 may be greater than 0 micrometers (μm) and less than or equal to 8 micrometers, or greater than 0 micrometers (μm) and less than or equal to 4 micrometers. According to some embodiments, the aforementioned width W2 may be the minimum width of the branch portion 130t in the second direction (e.g., the X direction in the figure). Furthermore, according to some embodiments, the width W2 is substantially the same as the width of the portion of the connection portion 130x that contacts the patterned electrode 130. According to some embodiments, the periphery of the patterned electrode 130 has a width W3, and the width W3 may be greater than 0 micrometers (μm) and less than or equal to 12 micrometers, or greater than 0 micrometers (μm) and less than or equal to 6 micrometers. For example, the width W3 may be substantially equal to 4 micrometers, but the present disclosure is not limited thereto.
[0105] It is worth noting that according to the embodiment of the present disclosure, the connecting portion 130x connecting the patterned electrode 130 and the switching unit 300 can be set at a specific position of the patterned electrode 130 (for example, at a corner point of a specific edge of the patterned electrode 130), thereby improving the liquid crystal arrangement stability of the display device 10 or reducing the problem of afterimages generated when the panel 10A is scratched by external force.
[0106] Specifically, according to some embodiments, when the liquid crystal layer 110 is doped with a left-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100a, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at a corner point of an even-numbered edge (e.g., the sixth edge e6) of the patterned electrode 130. According to other embodiments, when the liquid crystal layer 110 is doped with a left-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100b, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at a corner point of an odd-numbered edge (e.g., the seventh edge e7) of the patterned electrode 130. In other words, when the liquid crystal layer 110 is doped with a left-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on a substrate closer to the backlight module 10B, the connection portion 130x can be disposed at a corner point of an even-numbered edge of the patterned electrode 130. When the liquid crystal layer 110 is doped with a left-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on a substrate farther from the backlight module 10B, the connection portion 130x can be disposed at a corner point of an odd-numbered edge of the patterned electrode 130.
[0107] According to some embodiments, when the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100a, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at a corner point of an odd-numbered edge (e.g., the seventh edge e7) of the patterned electrode 130. According to other embodiments, when the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on the substrate 100b, the connection portion 130x connecting the patterned electrode 130 and the electrode through-hole 130v may be disposed at a corner point of an even-numbered edge (e.g., the sixth edge e6) of the patterned electrode 130. In other words, when the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on a substrate closer to the backlight module 10B, the connection portion 130x can be disposed at a corner point of an odd-numbered edge of the patterned electrode 130. When the liquid crystal layer 110 is doped with a right-handed chiral agent, and the patterned electrode 130 and the switch unit 300 are disposed on a substrate farther from the backlight module 10B, the connection portion 130x can be disposed at a corner point of an even-numbered edge of the patterned electrode 130.
[0108] Next, please refer to FIG. 4A to FIG. 4C , FIG. 4A to FIG. 4C The following is a schematic diagram of a partial top view of the structure of the display device 10 according to some other embodiments of the present disclosure. It should be understood that for the sake of clarity, FIG. 4A to FIG. 4C Only the patterned electrode 130 , the connecting portion 130 x and the electrode through hole 130 v are shown, and other components are omitted.
[0109] According to some embodiments, the edges of the four sub-portions of the patterned electrode 130 (i.e., the first edge e1, the second edge e2, the third edge e3, the fourth edge e4, the fifth edge e5, the sixth edge e6, the seventh edge e7, and the eighth edge e8) may all be closed (all have closed areas), but the present disclosure is not limited thereto. According to some embodiments, the edges of the four sub-portions of the patterned electrode 130 may have a closed area on one side (e.g., the seventh edge e7) and an open area on one side (e.g., the sixth edge e6) as in the above-mentioned embodiments. Furthermore, as Figure 4A As shown, according to some embodiments, the connection portion 130x may be disposed on the closed sixth edge e6, for example, may be disposed on a corner point of the sixth edge e6. Figure 4B As shown, according to some embodiments, the connection portion 130x may be disposed on the boundary between the sixth edge e6 and the seventh edge e7, for example, the connection portion 130x may be located in the extension direction of the main body 130m. Figure 4C As shown, according to some embodiments, the connection portion 130x may be disposed on the seventh edge e7, for example, may be disposed on a corner point of the seventh edge e7.
[0110] Please refer to FIG. 5A to FIG. 5D , FIG. 5A to FIG. 5D The top view of the patterned electrode 130 of the display device is shown in some embodiments of the present disclosure. FIG. 5A to FIG. 5D The patterned electrode 130 is disposed on the substrate 100 a and a left-handed chiral agent is doped, but the present disclosure is not limited thereto. Figure 5A The top view of the patterned electrode 130 is shown when the patterned electrode 130 is not scratched or pressed by an external force. FIG. 5B to FIG. 5D The patterned electrode 130 is scratched by an external force (for example, please refer to Figure 3 , after being drawn along the direction in which the center line CL of the main body 130m substantially extends, the top view of the patterned electrode 130 is obtained. FIG. 5B to FIG. 5D The embodiments shown correspond to FIG. 4A to FIG. 4C The connection portion 130 is configured as shown. FIG. 5A to FIG. 5D The image is obtained through a microscope.
[0111] according to FIG. 4A to FIG. 4C and FIG. 5B to FIG. 5D It can be seen from the results shown that after being scratched by external force, the abnormal scratching phenomenon, such as the position ab1, position ab2 and position ab3 (such as dark lines) marked in the figure, tends to extend toward the position of the connecting part 130x, that is, the position where the abnormal phenomenon occurs roughly corresponds to the position of the connecting part 130x with the patterned electrode 130.
[0112] Next, please refer to FIG. 6A to FIG. 6C as well as FIG. 7A to FIG. 7C , FIG. 6A to FIG. 6C as well as FIG. 7A to FIG. 7C The following is a schematic diagram of a partial top view of the structure of the display device 10 according to some other embodiments of the present disclosure. It should be understood that for the sake of clarity, FIG. 6A to FIG. 6C as well as FIG. 7A to FIG. 7C Only the patterned electrode 130 , the connecting portion 130 x and the electrode through hole 130 v are shown, and other components are omitted.
[0113] like FIG. 6A to FIG. 6C As shown, according to some embodiments, the connection portion 130x may be located in the extension direction of the main body 130m, and the position of the electrode through-hole 130v may be set at a corner point adjacent to the sixth edge e6 (eg, Fig. 6A The electrode through hole 130v may be located near the boundary between the sixth edge e6 and the seventh edge e7 (as shown in FIG. Figure 6B Alternatively, the electrode through-hole 130v may be located at a corner point adjacent to the seventh edge e7 (eg Figure 6C As shown), the patterned electrode 130 can be electrically connected to the switch unit 300 through the electrode through-hole 130v.
[0114] Furthermore, if FIG. 7A to FIG. 7C As shown, according to some embodiments, the electrode through-hole 130v may be fixedly disposed at a boundary adjacent to the sixth edge e6 and the seventh edge e7, and the connecting portion 130x may be disposed at a corner point of the sixth edge e6 and a corner point of the seventh edge e7 (eg, Fig. 7A As shown), the connecting portion 130x may be disposed between the corner point of the sixth edge e6 and the center line CL of the main body 130m (as shown Figure 7B As shown), or the connecting portion 130x may be disposed between the corner point of the seventh edge e7 and the center line CL of the main body 130m (as shown Figure 7C shown).
[0115] Next, please refer to Figure 8 , Figure 8 A diagram showing the relationship between the location of the connection portion 130x and the electrode through hole 130v of the display device 10 and the safety voltage according to some embodiments of the present disclosure. Figure 8 The line segments viaR, viaC and viaL in the figure represent that the electrode through-holes 130v are arranged at the corner points adjacent to the seventh edge e7 (such as Figure 6C The electrode through hole 130v is configured in the embodiment of the present invention), the electrode through hole 130v is arranged at the boundary adjacent to the sixth edge e6 and the seventh edge e7 (such as Figure 6B The electrode through hole 130v is configured in the embodiment of the present invention and the electrode through hole 130v is arranged at a corner point adjacent to the sixth edge e6 (such as Fig. 6A The safe voltage changes of the embodiment of the electrode through hole 130v configuration in the embodiment when the connecting part 130x is set at different positions.
[0116] Figure 8 The horizontal axis in the figure represents the position where the connection portion 130x is set. Specifically, "e6+e7" may correspond to Fig. 7A The connection portion 130x configuration in the embodiment of the present invention can correspond to Figure 4A The connection portion 130x configuration in "e6.5" can correspond to Figure 7B The connection portion 130x configuration in the "eCL" may correspond to FIG. 6A to FIG. 6C In any of the configurations of the connection portion 130x, "e7.5" may correspond to Figure 7C The connection portion 130x configuration in the embodiment of the present invention can correspond to Figure 4C The connection portion 130x is configured in.
[0117] like Figure 8 As shown, the safety voltage change trends of line segments viaR, viaC and viaL are roughly similar when the connection portion 130x is set at different positions. Therefore, it can be seen that the setting position of the electrode through-hole 130v has a small impact on the safety voltage. Furthermore, when the position of the connection portion 130x is set at "e6.5" and "eCL", the safety voltage is lower. When the position of the connection portion 130x is set at "e7.5" and "e7", the safety voltage is higher, that is, when the connection portion 130x is set between the corner point of the seventh edge e7 and the center line CL of the main body 130m or is set at the corner point of the seventh edge e7, the safety voltage performance of the patterned electrode 130 is better.
[0118] In addition, it should be understood that according to the embodiment of the present disclosure, the definition of the safety voltage is: when the driving voltage of the switch unit 300 is less than or equal to the safety voltage, the degree of the scratching abnormality (such as dark lines) caused by the external force scratching the panel is less likely to be noticed by the observer. In other words, the scratching abnormality of the panel will not occur. On the contrary, when the driving voltage of the switch unit 300 is greater than the safety voltage, the scratching abnormality of the panel will begin to occur (such as dark lines). In other words, according to the embodiment of the present disclosure, by designing a higher safety voltage, the scratching abnormality can be reduced.
[0119] Furthermore, according to some embodiments, the panel 10A may be first switched to the highest grayscale or the highest voltage, and then an abnormal scratch screen may be generated on the panel 10A. The panel 10A may be scratched by an external force, and then the voltage of the display device 10 may be slowly reduced from the highest grayscale or the highest voltage of the display device 10 until the observer cannot observe the abnormal scratch screen on the panel 10A, and the voltage at this time is defined as the safe voltage. According to some embodiments, the highest grayscale of the panel 10A is, for example, 255 grayscales or 20Vpp, but the present disclosure is not limited thereto. It should be understood that the corresponding high voltage range may be different for different products.
[0120] Next, please refer to Fig. 9 , Fig. 9 The following is a schematic diagram of a partial top view of the structure of the display device 10 according to some other embodiments of the present disclosure. It should be understood that for the sake of clarity, Fig. 9 Only the patterned electrode 130 , the connecting portion 130 x and the electrode through hole 130 v are shown, and other components are omitted.
[0121] like Fig. 9 As shown, according to some embodiments, the patterned electrode 130 may include a first portion 1301 and a second portion 1302, and the first portion 1301 and the second portion 1302 may each include a main portion 130m and a plurality of branch portions 130t, and the branch portions 130t are connected to the main portion 130m. Specifically, according to some embodiments, the first portion 1301 of the patterned electrode 130 includes a sub-portion P1, a sub-portion P2, a sub-portion P3, and a sub-portion P4 arranged counterclockwise, and two edges of the sub-portion P1, the sub-portion P2, the sub-portion P3, and the sub-portion P4 are sequentially defined as a first edge e1, a second edge e2, a third edge e3, a fourth edge e4, a fifth edge e5, a sixth edge e6 (not indicated), a seventh edge e7 (not indicated), and an eighth edge e8. Furthermore, according to some embodiments, the second portion 1302 of the patterned electrode 130 also includes a sub-portion P1', a sub-portion P2', a sub-portion P3' and a sub-portion P4' arranged counterclockwise, and two edges of the sub-portion P1', the sub-portion P2', the sub-portion P3' and the sub-portion P4' are sequentially defined as a first edge e1', a second edge e2' (not indicated), a third edge e3' (not indicated), a fourth edge e4', a fifth edge e5', a sixth edge e6', a seventh edge e7' and an eighth edge e8'. According to some embodiments, the first portion 1301 and the second portion 1302 are defined as a pixel unit PX.
[0122] According to some embodiments, the first portion 1301 of the patterned electrode 130 may be electrically connected to the switch unit 300 (not shown) through the electrode through-hole 130v. In addition, according to some embodiments, the display device 10 may further include another switch unit 300 (not shown) and an electrode through-hole 130v' disposed adjacent to the second portion 1302, and the other switch unit 300 may be electrically connected to the second portion 1302 through the electrode through-hole 130v'. According to some embodiments, the voltages of the switch units 300 electrically connected to the first portion 1301 and the second portion 1302, respectively, may have a certain relationship or be mutually adjusted, thereby improving the color shift problem of the panel at a side viewing angle.
[0123] It should be understood that Fig. 9The position of the connection portion 130x is only schematically shown, and the position of the connection portion 130x can be set according to the rules described in the above embodiments. For example, according to some embodiments, the connection portion 130x connected to the electrode through-hole 130v and the electrode through-hole 130v' can be respectively set at the third edge e3 of the first part 1301 and the seventh edge e7' of the second part to further improve the stability of the liquid crystal arrangement.
[0124] Next, please refer to Fig.10 and Fig.11 , Fig.10 and Fig.11 A partial top view of the structure of the display device 10 according to some other embodiments of the present disclosure is shown. Fig.10 and Fig.11 As shown, according to some embodiments, adjacent patterned electrodes 130 (e.g., adjacent patterned electrodes 130-1 and patterned electrodes 130-2) can be electrically connected to different data lines DL located on both sides of the patterned electrodes 130 through the connection portions 130x. In detail, adjacent patterned electrodes 130 can be electrically connected to the data lines DL located on both sides of the patterned electrodes 130 (e.g., patterned electrodes 130-1 and patterned electrodes 130-2) through the electrode through holes 130v and the switch units 300 (e.g., switch units 300-1 and switch units 300-2).
[0125] like Fig.10 As shown, according to some embodiments, the patterned electrode 130-1 and the patterned electrode 130-2 are disposed adjacent to each other. According to some embodiments, the edge E130 of the patterned electrode 130-1 has an open area OP-1 and a closed area CP-1, and the edge E130 of the patterned electrode 130-2 has an open area OP-2 and a closed area CP-2.
