Description

Technical Field

[0001] This disclosure relates to electronic devices, and more particularly to electronic devices having conductive adhesive. Background Technology

[0002] With the rapid development of flat panel display technology and the decreasing manufacturing costs, flat panel display devices, which offer advantages such as low radiation, small thickness, and low power consumption, are increasingly favored by consumers and are therefore widely used in electronic devices such as mobile phones, game consoles, and PDAs. Generally speaking, flat panel display devices mainly include plasma display panels (PDP), liquid crystal displays (LCD), and organic light-emitting diode (OLED) displays. Among these, LCD displays, due to their relatively low cost, have gradually become the mainstream flat panel display device on the market.

[0003] In the evolution of electronic devices, to meet the demands for high resolution and achieve high production capacity, the size of display devices has been continuously miniaturized, creating many unresolved challenges in the manufacturing process. While existing electronic devices generally meet their requirements, they are not satisfactory in all aspects. Therefore, improvements to the structure of electronic devices are still needed to manufacture devices that meet product requirements and improve visual effects. Summary of the Invention

Alternatively, it could refer to a situation where the membrane layer is not in direct contact with other membrane layers, in which case one or more intermediate layers are disposed between the membrane layer and other membrane layers.

[0032] It should be understood that the ordinal numbers used in the specification and claims, such as "first," "second," etc., to modify components, do not in themselves imply or represent any prior ordinal number for that (or these) components, nor do they represent the order of one component with another, or the order of manufacture. The use of these ordinal numbers is solely to clearly distinguish one named component from another component with the same name. The claims and specification may not use the same terminology; for example, the first component in the specification may be the second component in the claims.

[0033] The term "about" as used herein generally means within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range. The given quantities are approximate, meaning that the term "about" may be implied even without a specific mention. Furthermore, the phrases "range from the first value to the second value," "range between the first value and the second value," and "range greater than or equal to the first value and less than or equal to the second value" indicate that the range includes the first value, the second value, and other values ​​in between.

[0035] According to embodiments of this disclosure, an optical microscopy (OM), a scanning electron microscope (SEM), an alpha-step thickness gauge, an ellipsometry, or other suitable methods can be used to measure the spacing or distance between components, or the width, thickness, height, or area of ​​each component.

[0037] According to some embodiments of this disclosure, an electronic device is provided. The electronic device includes a polarizer and a conductive adhesive disposed on a first substrate. The conductive adhesive is adjacent to the edge of the polarizer, and the extension direction of the conductive adhesive has an angle between 80 degrees and 100 degrees with the absorption axis direction of the polarizer. In this way, the probability of the conductive adhesive penetrating into the polarizer in a humid and warm environment can be reduced, thereby affecting the visual effect of the surrounding area of ​​the electronic device.

[0040] Figures 1A and 1B are top views and cross-sectional views of the electronic device 10, respectively, according to some embodiments of the present disclosure. It should be noted that... Figure 1B The cross-sectional view is along Figure 1A The image is captured by section line A-A'. Referring to Figures 1A and 1B, the electronic device 10 includes a first substrate 100 and a polarizer 104 and conductive adhesive 106 disposed on the first substrate 100. Figure 1BAs shown, the polarizer 104 has a conductive layer 1042, and the conductive adhesive 106 is electrically connected to the conductive layer 1042 of the polarizer 104. In some embodiments, the conductive layer 1042 of the polarizer 104 can serve as an antistatic layer, which can reduce the impact of excessive static charge accumulation on the surface of the electronic device 10 on the touch performance of the electronic device 10. The conductive adhesive 106, electrically connected to the conductive layer 1042, can provide an electrostatic conduction path for the electronic device 10, so as to conduct the static electricity accumulated on the surface of the electronic device 10 to other conductive structures on the first substrate 100, thereby improving the display quality and touch performance of the electronic device 10.

[0041] In some embodiments, although not explicitly shown in Figures 1A and 1B and subsequent figures, the first substrate 100 may, for example, include a substrate, a thin film transistor layer (TFT layer) disposed on the substrate and serving as a driving circuit, an electrode layer disposed on the substrate and electrically connected to the TFT layer, and / or an alignment layer disposed above the TFT layer and the electrode layer. The alignment layer can be used to align the liquid crystal molecules in the liquid crystal layer and give them a desired orientation.

[0042] In some embodiments, the conductive layer 1042 of the polarizer 104 may include, for example, pressure-sensitive adhesive (PSA), but is not limited thereto. In some embodiments, the material of the conductive layer 1042 may contain carboxyl groups, hydroxyl groups, esters, or combinations thereof, but this disclosure is not limited thereto. According to some embodiments, a surface resistance of the conductive layer 1042 may be between about 10 Ω. 8 Ω / □ to approximately 10 10 The value is between Ω / □, where Ω / □ is a commonly used unit for sheet resistance (also known as block resistance) in this field. For example, approximately 2.5 x 10⁻⁶. 8 Ω / □, approximately 5x10 8 Ω / □、7.5x10 8 Ω / □ or approximately 1.5 x 10 9 Ω / □. In some embodiments, the conductive layer 1042 is in the normal direction of the first substrate 100 (e.g., Figure 1B The thickness 1042T (on the Z-axis) can be between 1 μm and 30 μm, for example, about 10 μm. A conductive layer 1042 with a resistance and thickness within the above range can maintain good touch sensitivity and achieve the desired antistatic effect. In some embodiments, the material of the conductive adhesive 106 may include copper, silver, or the aforementioned alloys, but is not limited thereto.

[0043] like Figure 1AAs shown, the conductive adhesive 106 is adjacent to the edge of the polarizer 104 and along the horizontal direction (e.g., Figure 1A The conductive adhesive 106 extends laterally along the X-axis of the polarizer 104. Furthermore, the extension direction of the conductive adhesive 106 has an angle between 80 and 100 degrees, for example, approximately 90 degrees, with respect to the absorption axis of the polarizer 104. During the fabrication of the polarizer 104, the secondary layers within the polarizer 104 are stretched to have an absorption axis extending along a specific direction. However, when stretching the secondary layers of the polarizer 104, the secondary layers shrink in a direction perpendicular to the stretching direction, causing misalignment between the secondary layers of the polarizer 104. If the conductive adhesive 106 forms along the inwardly shrinking edge of the secondary layers of the polarizer 104, the conductive adhesive 106 may penetrate into the polarizer 104 in a humid and warm environment. Therefore, when the conductive adhesive 106 is designed to have an angle between its extension direction and the absorption axis of the polarizer 104 within the aforementioned range, the probability of the conductive adhesive 106 penetrating into the polarizer 104 can be reduced, thereby maintaining the visual effect of the area surrounding the electronic device 10. Moreover, the above design also facilitates the development of electronic devices 10 towards extremely narrow bezels.

[0044] According to some embodiments, the absorption axis direction of a polarizer with a known absorption axis direction can be determined using a polarizer with a known absorption axis direction. Specifically, the polarizer with the known absorption axis direction is first overlapped with the polarizer to be tested. Then, the polarizer with the known absorption axis direction is rotated until light cannot penetrate both polarizers. When light cannot penetrate the overlapping polarizers, the absorption axis directions of the two polarizers will be perpendicular to each other, thus revealing the absorption axis direction of the polarizer to be tested. In other embodiments, the absorption axis direction can be measured by a spectrophotometer (e.g., a JASCO V-7100 spectrophotometer). This instrument can strike a linear polarizer with incident light to form linearly polarized light. This linearly polarized light strikes the sample to be tested, and by rotating it at different angles, the optical properties of the sample (absorption axis angle, polarization brightness, transmittance, etc.) can be obtained. However, this disclosure is not limited to this.

[0045] According to some embodiments, such as Figure 1B As shown, the polarizer 104 may further include a polarizing film 1044. In some embodiments, the conductive adhesive 106 may contact the edge of the polarizer 104. In one embodiment, the conductive adhesive 106 contacts at least the conductive layer 1042 of the polarizer 104. In one embodiment, the conductive adhesive 106 may contact both the conductive layer 1042 and the polarizing film 1044 of the polarizer 104. Although Figure 1B Although not explicitly shown in the following figures, it should be understood that, depending on the embodiment, the polarizing film 1044 of the polarizer 104 can be a single-layer structure or a multi-layer structure containing multiple layers of polarizing films. The secondary polarizing film in the multi-layer structure can be a functional film layer that provides at least one of the following functions: anti-reflection, anti-glare, anti-fouling, and improved light transmittance.

[0046] According to some embodiments, as shown in Figures 1A and 1B, the interface between the conductive adhesive 106 and the polarizer 104 is the contact area 106CR, and a portion of the contact area 106CR is the area where the conductive adhesive 106 contacts the conductive layer 1042. In some embodiments, in Figure 1A In the top view shown, the area where the conductive adhesive 106 contacts the conductive layer 1042 is along the extension direction of the conductive adhesive 106 (e.g., Figure 1A The length 106L of the X-axis in the polarizer 104 can be greater than the extension direction of the conductive adhesive 106 (e.g., ...). Figure 1A The width 104W (on the X-axis) is approximately 10%, for example, greater than approximately 20%, approximately 30%, approximately 40%, approximately 50%, approximately 60%, approximately 70%, approximately 80%, or approximately 90%. If the length 106L is too short, for example less than approximately 10% of the width 104W, the conductive adhesive 106 cannot effectively conduct static electricity accumulated on the surface of the electronic device 10. Furthermore, in some embodiments, the area where the conductive adhesive 106 contacts the conductive layer 1042 is along the extension direction of the conductive adhesive 106 (e.g., along the X-axis). Figure 1A The length 106L of the X-axis in the polarizer 104 can be equal to the extension direction of the conductive adhesive 106 along the polarizer 104 (e.g., Figure 1A The width of the X-axis is 104W.

[0047] According to some embodiments, such as Figure 1B As shown, the contact area 106CR is along the normal direction of the first substrate 100 (e.g., Figure 1B The Z-axis (in the image) may have a width of 106W. That is, the width 106W is the height of the contact interface between the conductive adhesive 106 and the polarizer 104. In some embodiments, the width 106W may be greater than or equal to the conductive layer 1042 of the polarizer 104 in the normal direction of the first substrate 100 (e.g., ...). Figure 1B The thickness is 1042T on the Z-axis. In some embodiments, the width 106W may be between about 1 μm and about 250 μm.

[0048] In some embodiments, the electronic device 10 may further include a second substrate 102. The second substrate 102 is disposed between the first substrate 100 and the polarizer 104. Figure 1BAs shown, conductive adhesive 106 may be further disposed on the second substrate 102. According to some embodiments, the second substrate 102 may include a substrate, which may include a color filter and a light-shielding layer. In one embodiment, the second substrate 102 may further include an alignment layer. In embodiments where the second substrate 102 includes an alignment layer, the alignment layer may be disposed on the side of the substrate where the polarizer 104 is not disposed. In other embodiments, the second substrate may not include a color filter and a light-shielding layer, but this disclosure is not limited thereto. The substrates of the first substrate 100 and the second substrate 102 of this disclosure may be flexible or non-flexible substrates, and the materials may include plastics, glass, quartz, sapphire, ceramics, carbon fiber, other suitable substrate materials, or combinations thereof, but are not limited thereto. In some embodiments, the aforementioned plastic material may include polyimide (PI), polyethylene terephthalate (PET), polycarbonate (PC), other suitable materials, or combinations thereof, but are not limited thereto. In other embodiments, the second substrate 102 may be replaced by an encapsulation layer that provides protection, encapsulation, and / or planarization for the display unit, and the encapsulation layer may contain organic materials, inorganic materials, combinations thereof, or mixtures thereof, but is not limited thereto.

[0049] In some embodiments, the polarizer 104 may contact the second substrate 102. In one embodiment, the polarizer 104 may directly contact the second substrate 102. More specifically, in one embodiment, the conductive layer 1042 of the polarizer 104 may contact the second substrate 102. According to some embodiments, such as Figure 1B As shown, the conductive adhesive 106 may have a thickness 106T2 extending from the upper surface 102US of the second substrate 102 to the topmost surface 106TS of the conductive adhesive 106. In some embodiments, the thickness 106T2 may be less than that of the polarizer 104 in the normal direction of the first substrate 100 (e.g., Figure 1B The thickness of the conductive adhesive 106 (Z-axis) is 104T. The thickness of the conductive adhesive 106 is 106T2, which is less than the thickness of the polarizer 104, that is, the horizontal plane of the top surface 106TS of the conductive adhesive 106 is lower than the upper surface of the polarizer 104, which can reduce the risk of light leakage and reduce the possibility of damage during the assembly of the electronic device 10.

[0050] In some embodiments, the thickness 106T2 of the conductive adhesive 106 may be between about 1 and about 250 μm. In some embodiments, the thickness 104T of the polarizer 104 may be between about 50 μm and about 250 μm.

[0051] Referring again to Figures 1A and 1B, in some embodiments, the electronic device 10 may further include a conductive pad 108. The conductive pad 108 may be disposed on the first substrate 100. More specifically, in one embodiment, the conductive pad 108 may be disposed on a portion of the first substrate 100 that does not overlap with the second substrate 102. In some embodiments, in addition to providing the conductive pad 108, the portion of the first substrate 100 that does not overlap with the second substrate 102 may be used as an area for electrically connecting a flexible printed circuit board, electrically connecting a driver integrated circuit chip, or bonding a driver integrated circuit chip, but this disclosure is not limited thereto.

[0052] According to some embodiments, the conductive pad 108 may be electrically connected to the conductive adhesive 106 to further provide a pathway for static discharge of static electricity transmitted through the conductive adhesive 106. In some embodiments, such as Figure 1B As shown, conductive adhesive 106 may be formed on conductive pad 108 and extend from conductive pad 108 to the first substrate 100 and the second substrate 102. According to some embodiments, the material of conductive pad 108 may include aluminum (Al), copper (Cu), molybdenum (Mo), titanium (Ti), platinum (Pt), iridium (Ir), nickel (Ni), chromium (Cr), silver (Ag), gold (Au), tungsten (W), or alloys thereof, but is not limited thereto.

[0053] Refer again Figure 1B In some embodiments, the electronic device 10 may further include a liquid crystal layer 103. The liquid crystal layer 103 is sandwiched between the first substrate 100 and the second substrate 102. In some embodiments, as shown in Figures 1A and 1B, the projection surfaces of the liquid crystal layer 103 and the second substrate 102 onto the first substrate 100 may overlap. Therefore, in Figure 1A In the top view, the second substrate 102 may cover the liquid crystal layer 103.

[0054] Refer again Figure 1B In some embodiments, an additional polarizer 110 may be disposed on the side of the first substrate 100 where the liquid crystal layer 103 is not located. Similarly, the polarizer 110 may have a similar or identical composition to the polarizer 104. According to some embodiments, the polarizer 110 may be a single-layer structure or a multilayer structure comprising multiple layers of polarizing films. The secondary polarizing film in the multilayer structure may be a functional film layer providing at least one of the following functions: anti-reflection, anti-glare, anti-fouling, and improved light transmittance.

[0055] Next, refer to Figure 1C , Figure 1C The illustrations are based on some embodiments of the present disclosure. Figure 1B A partial enlarged view of the electronic device 10. It should be noted that... Figure 1C It is extracted from Figure 1BRegion R in the image. According to some embodiments, the polarizing film 1044 of the polarizer 104 may include secondary polarizing films 1044A, 1044B, and 1044C. Although in Figure 1C The intermediate polarizing film 1044 is only shown with three layers of polarizing film (sub-polarizing films 1044A, 1044B, and 1044C), but this disclosure is not limited thereto. In other embodiments, the polarizing film 1044 may include fewer or more layers of sub-polarizing film.

[0056] As previously described, during the formation of polarizer 104, the secondary layers (e.g., ...) within polarizer 104 Figure 1C The secondary polarizing films 1044A, 1044B, and 1044C in the polarizer 104 are stretched to have an absorption axis extending along a specific direction. However, during the stretching of the secondary layers of the polarizer 104, the secondary layers shrink in a direction perpendicular to the stretching direction, causing misalignment between the secondary layers of the polarizer 104. Figure 1C As shown, if the extension direction of the conductive adhesive 106 has an angle between approximately 80 degrees and approximately 100 degrees with the absorption axis direction of the polarizer 104, the subpolarizing films 1044A, 1044B, and 1044C of the polarizer 104 are in the extension direction of the conductive adhesive 106 (e.g., Figure 1C The X-axis (in the image) may not have an inwardly recessed edge. Therefore, the penetration of conductive adhesive 106 into polarizer 104 can be reduced, thereby affecting the display effect of electronic device 10.

[0057] Reference Figure 2 , Figure 2 The above view of the electronic device 20 is shown according to other embodiments of the present disclosure. Figure 2 Electronic device 20 and Figure 1A The electronic device 20 is similar to the electronic device 10, but the conductive adhesive 106 of the electronic device 20 extends in a different direction than the conductive adhesive 106 in the electronic device 10. Specifically, as Figure 2 As shown, the conductive adhesive 106 may be adjacent to the edge of the polarizer 104 and extend longitudinally along the Y-axis. In one embodiment, the portion of the conductive adhesive 106 extending along the edge of the polarizer 104 may contact the edge of the polarizer 104.

[0058] Furthermore, the extension direction of the conductive adhesive 106 in the electronic device 20 can have an angle between approximately 80 degrees and approximately 100 degrees with the absorption axis direction of the polarizer 104, for example, approximately 90 degrees. Similarly, having the angle between the extension direction of the conductive adhesive 106 and the absorption axis direction of the polarizer 104 within the aforementioned range reduces the possibility of the conductive adhesive 106 penetrating into the polarizer 104, thereby affecting the visual effect of the surrounding area of ​​the electronic device 20. Moreover, the above design also facilitates the development of the electronic device 20 towards extremely narrow bezels.

[0059] exist Figure 2 In the illustrated embodiment, the interface between the conductive adhesive 106 and the polarizer 104 is in the extending direction of the conductive adhesive 106 (e.g., Figure 2 The length of the polarizer 104 (on the Y-axis) is greater than about 10% of the length of the polarizer 104 in the extension direction of the conductive adhesive 106, for example, greater than about 20%, about 30%, about 40%, about 50%, about 60%, about 70%, about 80%, or about 90%. If the interface between the conductive adhesive 106 and the polarizer 104 is in the extension direction of the conductive adhesive 106 (e.g., ...), Figure 2 If the length of the polarizer 104 (on the Y-axis) is too short, for example, less than about 10% of the length of the polarizer 104 in the extension direction of the conductive adhesive 106, the conductive adhesive 106 cannot effectively conduct static electricity accumulated on the surface of the electronic device 20. Furthermore, in some embodiments, the interface between the conductive adhesive 106 and the polarizer 104 is in the extension direction of the conductive adhesive 106 (e.g., ...). Figure 2 The length of the Y-axis in the polarizer 104 can be equal to the length of the polarizer 104 along the extension direction of the conductive adhesive 106.

[0060] In summary, according to some embodiments of this disclosure, the electronic device includes a polarizer and a conductive adhesive disposed on a first substrate. The conductive adhesive is adjacent to the edge of the polarizer, and the extension direction of the conductive adhesive has an angle between 80 and 100 degrees with the absorption axis direction of the polarizer. This reduces the likelihood of the conductive adhesive penetrating into the polarizer in a humid and warm environment, thereby affecting the visual effect of the surrounding area of ​​the electronic device.
