[0073] The following is a detailed description of the electronic 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 elements 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 elements to clearly describe the present disclosure. However, the use of these similar and / or corresponding numbers is only for the 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.

[0074] 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 elements in the drawings are not drawn according to the actual scale. In addition, the number and size of each element in the drawings are only for illustration and are not intended to limit the scope of the present disclosure.

[0075] It should be understood that the elements 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 element of the drawings to another element. It is understandable that if the device of the drawings is turned upside down, the element described on the "lower" side will become the element 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 to be part of the disclosure. Furthermore, when it is mentioned that a first material layer is 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] In addition, it should be understood that although the terms "first", "second", "third", etc. may be used herein to describe various elements, components, or parts, these elements, components, or parts should not be limited by these terms. These terms are only used to distinguish different elements, components, regions, layers, or parts. Therefore, a first element, component, region, layer, or part discussed below may be referred to as a second element, component, region, layer, or part without departing from the teachings of the present disclosure.

[0080] 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.

[0081] 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.

[0082] 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 0 degrees and 10 degrees.

[0083] 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.

[0084] According to some embodiments of the present disclosure, an electronic device is provided, which can improve the light transmittance of the electronic device by adding a chiral agent (chiral dopant) in the liquid crystal layer and adjusting the angle between the absorption axis of the polarizer and the patterned electrode. According to some embodiments of the present disclosure, the design of the patterned electrode can be further matched to reduce the problem of dark lines generated in the edge area of ​​the patterned electrode due to the influence of the chirality of the liquid crystal.

[0085] According to some embodiments of the present disclosure, the electronic device may include a display device, a light-emitting device, a touch device, a sensing device, a splicing device, or a combination thereof, but is not limited thereto.

[0104] According to the embodiment of the present disclosure, the relationship between the first angle φ1 and the second angle φ2 can be adjusted as described above according to the chiral agent selected in the liquid crystal layer 130 (for example, a left-handed chiral agent or a right-handed chiral agent) or the setting position of the patterned electrode 130 (for example, between the first substrate 100a and the liquid crystal layer 110 or between the second substrate 100b and the liquid crystal layer 110). Through the above adjustment, the angle between the average direction of the liquid crystal and the absorption axis direction of the polarizing plate can be approximately 45 degrees, thereby improving the transmittance or brightness uniformity of the panel.

[0105] Although in Figure 2In the illustrated embodiment, the first angle φ1 and the second angle φ2 are only indicated in the first sub-portion P1 of the patterned electrode 130, but the present invention is not limited thereto. According to some embodiments, the design of the patterned electrode 130 (branch portion 130t) of the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4 also conforms to the aforementioned relationship between the first angle φ1 and the second angle φ2, and the definitions of the first angle φ1 and the second angle φ2 are similar.

[0106] Please refer to Figure 3 , Figure 3 The top view of the patterned electrode 130 of the electronic device according to some other embodiments of the present disclosure is shown. Figure 3 As shown, according to some embodiments, the extension direction of the branch portion 130t in the first sub-portion P1 and / or the third sub-portion P3 of the patterned electrode 130 is substantially perpendicular to the first absorption axis AX1 (i.e., substantially perpendicular to the second absorption axis AX2), and the extension direction of the branch portion 130t in the second sub-portion P2 and / or the fourth sub-portion P4 is substantially perpendicular to the second absorption axis AX2 (i.e., substantially perpendicular to the first absorption axis AX1). According to some embodiments, the extension direction of the branch portion 130t in the first sub-portion P1 (and / or the third sub-portion P3) may be substantially perpendicular to the extension direction of the branch portion 130t in the second sub-portion P2 (and / or the fourth sub-portion P4). According to some embodiments, the number of the branch portions 130t in the first sub-portion P1 (and / or the third sub-portion P3) may be different from the number of the branch portions 130t in the second sub-portion P2 (and / or the fourth sub-portion P4).

[0107] like Figure 3 As shown, in this embodiment, the sum of a first angle φ1 (approximately 90 degrees) between at least one branch portion 130t in a sub-portion and the first absorption axis AX1 and a second angle (not marked, but may be approximately 0 degrees) between the branch portion 130t and the second absorption axis AX2 is approximately 90 degrees, and the size relationship between the first angle φ1 and the second angle φ2 is also different in accordance with the position of the aforementioned patterned electrode 130 and the characteristics of the chiral agent in the liquid crystal layer 110, so this part will not be repeated.

[0108] Next, please refer to Figure 4A , Figure 4AA graph showing the relationship between the polarizing plate arrangement angle and the transmittance of an electronic device according to some embodiments of the present disclosure is shown. For example, when the liquid crystal layer 110 of the electronic device includes a left-handed chiral agent, the patterned electrode 130 is disposed between the first substrate 100a and the liquid crystal layer 110, and the absorption axis angle between the lower polarizing plate and the upper polarizing plate of the electronic device is fixed at about 90 degrees (i.e., the first absorption axis AX1 and the second absorption axis AX2 are about 90 degrees apart), the transmittance variation relationship between different electrode angles θA and different absorption axis arrangement angles θu of the upper polarizing plate is shown. The above-mentioned electrode angle θA (such as Figure 2 ) can be defined as the angle between the extension direction EX2 of the short axis portion 130m-1 in the main portion 130m and the extension direction EX of one of the plurality of branch portions 130t. Figure 2 In the embodiment, the extension direction EX3 of the long axis portion 130m-2 of the main body portion 130m is substantially perpendicular to the extension direction EX2 of the short axis portion 130m-1. Figure 4A , showing the transmittance curves at different electrode angles θA (θA is 0 degrees, 22.5 degrees, 45 degrees, 67.5 degrees, 90 degrees) and different upper polarizer absorption axis placement angles θu (such as the horizontal axis angle in FIG4 ). When the upper polarizer absorption axis placement angle θu is 0 degrees, it is defined that the extension direction of the absorption axis is roughly in the X direction (refer to Figure 2 As shown in the figure, when the extension direction of the absorption axis rotates 20 degrees (or 40 degrees) counterclockwise, the arrangement angle θu is 20 degrees (or 40 degrees); conversely, when the extension direction of the absorption axis rotates about 20 degrees (or 40 degrees) clockwise, the arrangement angle θu is -20 degrees (or -40 degrees). It should be noted that if Figure 4A As shown, it can be obtained that at different electrode angles θA and the arrangement angles θu of the absorption axis of the upper polarizer, there are maximum values ​​of transmittance (transmittance is about 90% to about 95%, but not limited thereto). Figure 4A As a result, when the electrode angle θA is fixed, a better transmittance can be achieved by adjusting the arrangement angle θu of the upper polarizer. Alternatively, when the arrangement angle θu is fixed, a better transmittance can be achieved by adjusting the electrode angle θA. For example, when the arrangement angle θu is fixed to 0 degrees, the electrode angle θA can be designed to be about 70 degrees to obtain a better transmittance, but is not limited thereto.

[0109] then, Figure 4BA graph showing the relationship between the polarizing plate arrangement angle and the transmittance of an electronic device according to other embodiments of the present disclosure is shown. For example, when the liquid crystal layer 110 of the electronic device includes a right-handed chiral agent, the patterned electrode 130 is disposed between the first substrate 100a and the liquid crystal layer 110, and the absorption axis angle between the lower polarizing plate and the upper polarizing plate of the electronic device is fixed at about 90 degrees (i.e., the first absorption axis AX1 and the second absorption axis AX2 are about 90 degrees), the transmittance variation relationship between different electrode angles θA and different absorption axis arrangement angles θu of the upper polarizing plate is shown. The above-mentioned electrode angle θA and arrangement angle θu are defined and described as above. As Figure 4B As shown, it can be obtained that at different electrode angles θA and arrangement angles θu, there will be maximum values ​​of transmittance (transmittance is about 90% to about 95%, but not limited to this). Figure 4A As a result, when the electrode angle θA is fixed, a better transmittance can be achieved by adjusting the arrangement angle θu of the upper polarizer. Alternatively, when the arrangement angle θu is fixed, a better transmittance can be achieved by adjusting the electrode angle θA. According to some embodiments, the transmittance of the electronic device can be measured by a spectrometer or other instrument that can measure brightness. For example, the transmittance can be measured when the panel 10A and the backlight source 10B are assembled.

[0110] Next, please refer to Figure 5 and Figure 6 , Figure 5 The top view of the patterned electrode 130 of the electronic device according to some other embodiments of the present disclosure is shown next. Figure 6 The top view of the patterned electrode 130 of the electronic device according to some other embodiments of the present disclosure is shown. According to some embodiments, at least a portion of the sub-portion 130p (the first sub-portion P1, the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4) may include a peripheral portion, for example, may include at least a first peripheral portion 130S-1 (such as Figure 5 ) and / or at least one second peripheral portion 130S-2 (as shown Figure 6, but not limited thereto. It should be noted that the first peripheral portion 130S-1 is defined as the peripheral portion of the patterned electrode 130 corresponding to the even-numbered edges as described above. The even-numbered edges include, for example, the second edge E2, the fourth edge E4, the sixth edge E6 and / or the eighth edge E8 described above. It should be noted that the second peripheral portion 130S-2 is defined as the peripheral portion of the patterned electrode 130 corresponding to the odd-numbered edges as described above. The odd-numbered edges include, for example, the first edge E1, the third edge E3, the fifth edge E5 and / or the seventh edge E7 described above. According to some embodiments, the first peripheral portion 130S-1 and / or the second peripheral portion 130S-2 may be connected to the main portion 130m and / or at least one branch portion 130t. It is worth noting that dark lines are generated due to the influence of the chiral agent that the liquid crystal arrangement at the peripheral edge of the patterned electrode 130 may be affected. For example, taking the case where the liquid crystal layer 110 includes a left-handed chiral agent, when the patterned electrode 130 is disposed between the first substrate 100a and the liquid crystal layer 110, dark lines may be generated at the even-numbered edges of the patterned electrode 130, and when the patterned electrode 130 is disposed between the second substrate 100b and the liquid crystal layer 110, dark lines may be generated at the odd-numbered edges of the patterned electrode 130. Conversely, taking the case where the liquid crystal layer 110 includes a right-handed chiral agent, when the patterned electrode 130 is disposed between the first substrate 100a and the liquid crystal layer 110, dark lines may be generated at the odd-numbered edges of the patterned electrode 130, and when the patterned electrode 130 is disposed between the second substrate 100b and the liquid crystal layer 110, dark lines may be generated at the even-numbered edges of the patterned electrode 130. Therefore, the present disclosure can reduce the generation of edge dark lines or improve the brightness uniformity of the panel by designing the patterned electrode 130 to have a first peripheral portion 130S-1 and / or a second peripheral portion 130S-2 according to the chirality of the chiral agent and the different positions of the patterned electrode 130. For example, when the even edges in the patterned electrode 130 may generate dark lines, the generation of even edge dark lines can be reduced by designing the patterned electrode 130 to have at least one first peripheral portion 130S-1 (corresponding to the peripheral portion of the even edges as described above), but it is not limited to this. When the odd edges in the patterned electrode 130 may generate dark lines, the generation of odd edge dark lines can be reduced by designing the patterned electrode 130 to have at least one second peripheral portion 130S-2 (corresponding to the peripheral portion of the odd edges as described above), but it is not limited to this.

[0111] Specifically, according to some embodiments (such as Figure 5), when the liquid crystal layer 110 includes a left-handed chiral agent and the patterned electrode 130 is disposed between the first substrate 100a and the liquid crystal layer 110, at least a portion of the sub-portions (the first sub-portion P1, the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4) may include a first peripheral portion 130S-1 (a peripheral portion disposed on an even-numbered edge), but is not limited thereto. According to other embodiments (such as Figure 5 ), when the liquid crystal layer 110 includes a right-handed chiral agent and the patterned electrode 130 is disposed between the second substrate 100b and the liquid crystal layer 110, a small portion of the sub-portions (the first sub-portion P1, the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4) includes a portion disposed in the first peripheral portion 130S-1 (a peripheral portion disposed on an even-numbered edge), but is not limited thereto.

[0112] Specifically, according to some embodiments (such as Figure 6 ), when the liquid crystal layer 110 includes a left-handed chiral agent and the patterned electrode 130 is disposed between the second substrate 100b and the liquid crystal layer 110, at least a portion of the sub-portions (the first sub-portion P1, the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4) may include a portion disposed in the second peripheral portion 130S-2 (a peripheral portion disposed on an odd-numbered edge), but is not limited thereto. According to some embodiments (such as Figure 6 ), when the liquid crystal layer 110 includes a right-handed chiral agent and the patterned electrode 130 is disposed between the first substrate 100a and the liquid crystal layer 110, the first sub-portion P1, the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4 may include a second peripheral portion 130S-2 (a peripheral portion disposed on an odd edge), but is not limited thereto.

[0113] According to some embodiments, the width W1 of the first peripheral portion 130S-1 and / or the width W2 of the second peripheral portion 130S-2 may be between 1 micrometer (μm) and 7 micrometers (i.e., 1μm≤width W1 (or width W2)≤7μm), or between 3 micrometers and 7 micrometers (i.e., 3μm≤width W1 (or width W2)≤7μm), or between 4 micrometers and 6 micrometers (i.e., 4μm≤width W1 (or width W2)≤6μm), or, for example, 4 micrometers, 5 micrometers, or 6 micrometers. It should be noted that if the width W1 of the first peripheral portion 130S-1 or the width W2 of the second peripheral portion 130S-2 is too small (e.g., less than 1μm), the effect of reducing the peripheral dark lines may not be obvious. On the contrary, if the width W1 of the first peripheral portion 130S-1 or the width W2 of the second peripheral portion 130S-2 is too large (e.g., greater than 7μm), it may affect the liquid crystal arrangement in the plane or reduce the transmittance. The aforementioned width W1 refers to the maximum width of the first peripheral portion 130S-1 in a direction perpendicular to its extending direction. The aforementioned width W2 refers to the maximum width of the second peripheral portion 130S-2 in a direction perpendicular to its extending direction.

According to some embodiments, the distance D1 may be defined as the maximum distance between the outermost edge of the first peripheral portion 130S-1 or the second peripheral portion 130S-2 and the connection interface S in the X direction (e.g., the direction of the extension direction of the short side of the patterned electrode 130). According to some embodiments, the distance D1 may range from 4 microns to 12 microns (i.e., 4 μm≤distance D1≤12 μm), from 5 microns to 10 microns (i.e., 5 μm≤distance D1≤10 μm), or from 6 microns to 9 microns (i.e., 6 μm≤distance D1≤9 μm), for example, 7 microns or 8 microns, but is not limited thereto.

According to some embodiments, the angle θA-1 may be between 10 degrees and 30 degrees (i.e., 10 degrees ≤ angle θA-1 ≤ 30 degrees), for example, 20 degrees or 25 degrees, but is not limited thereto.

Figures 9 to 13 According to various embodiments, the patterned electrode 130 may be provided in various forms. According to some embodiments, the main body 130m of the patterned electrode 130 may have any suitable shape. Fig. 9 and Fig.10 As shown, the main body portion 130m may be in an X shape, and divide the patterned electrode 130 into a first sub-portion P1, a second sub-portion P2, a third sub-portion P3, and a fourth sub-portion P4. Fig. 9 and Fig.10 The size of the main body portion 130m shown in the embodiments is different. According to some embodiments, the number of branches 130t in the first sub-portion P1, the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4 may be the same or different, and the extension directions of the branches 130t in adjacent sub-portions are approximately 90 degrees apart, for example, the extension direction of the branch 130t in the first sub-portion P1 (not marked) and the extension direction of the branch 130t in the second sub-portion P2 (or the fourth sub-portion P4) are approximately 90 degrees apart, but not limited to this. According to some embodiments, the sizes of the areas of the first sub-portion P1, the second sub-portion P2, the third sub-portion P3 and / or the fourth sub-portion P4 may be the same or different. For example, as Fig. 9 or Fig.10 The sizes of the first sub-portion P1 and the third sub-portion P3 may be roughly similar, the sizes of the second sub-portion P2 and the fourth sub-portion P4 may be roughly similar, and the size of the first sub-portion P1 (or the third sub-portion P3) may be different from the second sub-portion P2 (or the fourth sub-portion P4), but is not limited thereto.

According to some embodiments, the upper electrode 130u and the lower electrode 130d each have a main body portion 130m, and the main body portion 130m can, for example, divide the upper electrode 130u into 4 sub-parts, such as a first sub-part P1, a second sub-part P2, a third sub-part P3, and a fourth sub-part P4, but is not limited thereto. Similarly, the main body portion 130m can, for example, divide the lower electrode 130d into 4 sub-parts, such as a first sub-part P1', a second sub-part P2', a third sub-part P3', and a fourth sub-part P4', but is not limited thereto. According to other embodiments, the patterned electrode 130 may have a greater or lesser number of main portions 130m or sub-portions as required.
