[0016] Throughout the specification and the appended claims of the present disclosure, certain terms are used to refer to specific components. Those skilled in the art should understand that electronic device manufacturers may refer to the same component by different names. This document is not intended to distinguish components that have the same function but different names. In the following specification and claims, words such as "comprising" and "including" are open-ended terms and should therefore be interpreted as meaning "including but not limited to...".

[0017] Directional terms mentioned herein, such as "upper", "lower", "front", "rear", "left", "right", etc., are only with reference to the directions in the drawings.

Non-direct connection means that there is at least one intermediate structure (or intermediate layer, intermediate component, intermediate substrate, intermediate interval) between the two structures. The lower surface of one structure is adjacent to or directly connected to the upper surface of the intermediate structure, and the upper surface of the other structure is adjacent to or directly connected to the lower surface of the intermediate structure. The intermediate structure may be composed of a single-layer or multi-layer solid structure or non-solid structure, without limitation.

The use of these ordinal numbers is only to clearly distinguish an element with a certain name from another element with the same name. The terms used in the claims and the specification do not have to be the same. Accordingly, the first component in the specification may be the second component in the claim.

[0020] The electrical connections or couplings described in this disclosure may refer to direct connections or indirect connections.

Additionally, there may be a certain error between any two values or directions being compared. Additionally, the terms "equal to", "equivalent", "the same", "substantially", or "approximately" mentioned in this disclosure generally represent within 10% of the given value or range. Furthermore, the expressions "the given range is from the first value to the second value" and "the given range falls within the range from the first value to the second value" mean that the given range includes the first value, the second value, and other values therebetween. If the first direction is perpendicular to the second direction, the angle between the first direction and the second direction can 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 can be between 0 degrees and 10 degrees.

[0027] Figure 1 FIG. is a schematic diagram of an electronic device according to an embodiment of the present disclosure. Figure 1 The electronic device 100 includes a panel 110 and polarizing elements (such as polarizing element 120 and polarizing element 130), which are disposed on one side of the panel 110. Specifically, the polarizing element 120 is disposed on the first side 110A of the panel 110, and the polarizing element 130 is disposed on the second side 110B of the panel 110, and the first side 110A and the second side 110B are opposite to each other. In some embodiments, the panel 110 may be a display panel, such as a liquid crystal display panel, an organic light emitting display panel, an electro-wetting display panel, an electrophoretic display panel, etc. or other suitable panels. In some embodiments, the polarizing element 120 and / or the polarizing element 130 are disposed on the outer surface of the panel 110, but are not limited thereto. In some embodiments, the polarizing elements (such as polarizing element 120 and polarizing element 130) include a multi-layer coating type polarizing layer. For example, the polarizing element 120 may include a multi-layer coating type polarizing layer 122, and the polarizing element 130 may include a multi-layer coating type polarizing layer 132. In some embodiments, the coating type polarizing layer 122 of the polarizing element 120 may be formed by a coating process. In some embodiments, the coating type polarizing layer 132 of the polarizing element 130 may be formed by a coating process. In some embodiments, the multi-layer coating type polarizing layers 122 may be in contact with each other or not in contact with each other. In some embodiments, the multi-layer coating type polarizing layers 132 may be in contact with each other or not in contact with each other. In some embodiments, the optical absorption axes of two adjacent coating type polarizing layers in the multi-layer coating type polarizing layer 122 are parallel to each other. In some embodiments, the optical absorption axes of two adjacent coating type polarizing layers in the multi-layer coating type polarizing layer 132 are parallel to each other.

[0028] In some embodiments, one of the multi-layer coated polarizing layers 122 / 132 contacts the panel 110. For example, the polarizing element 120 may directly contact the first side 110A of the panel 110 and include the multi-layer coated polarizing layer 122, or the polarizing element 130 may directly contact the second side 110B of the panel 110 and include the multi-layer coated polarizing layer 132. In some embodiments, one of the polarizing element 120 and the polarizing element 130 may be omitted. In some embodiments, one of the polarizing element 120 and the polarizing element 130 may be replaced by a stretched polarizing film.

[0029] Taking the manufacturing steps of the polarizing element 120 as an example, the manufacturing method of the electronic device 100 includes providing the panel 110 and disposing the polarizing element 120 on the first side 110A of the panel 110. The manufacturing method of the polarizing element 120 includes coating a polarizing layer material, such as a liquid crystal material, a liquid crystal material mixed with a dye, or other alternative materials, on the panel 110, and curing the polarizing layer material into a layer to form the first coated polarizing layer 122, but not limited thereto. Then, the steps of coating and curing are repeated on the formed coated polarizing layer 122 to sequentially form the second layer and other coated polarizing layers 122. The first coated polarizing layer 122 is closer to the panel 110 than the second layer and other coated polarizing layers 122, and the first coated polarizing layer 122 can contact the panel 110. That is to say, there is no other film layer between the first coated polarizing layer 122 and the panel 110, but not limited thereto.

[0030] When the polarizing layer material is coated on the panel 110, the molecules in the polarizing layer material can be arranged, for example, generally conforming to the coating direction (such as the traveling direction of the coating head). Subsequently, after the polarizing layer material is cured, the orientation of the molecules in the polarizing layer material is fixed, but not limited thereto. In some embodiments, when the polarizing layer material is a liquid crystal material, the orientation of the liquid crystal material is fixed and can have optical directivity. Therefore, the coated polarizing layer 122 fabricated in this way has polarization. The absorption axis of the coated polarizing layer 122 can be determined generally according to the coating direction. In some embodiments, in the coated polarizing layer 122 formed by the coating method, the liquid crystal material closer to the panel 110 may be arranged more neatly. Therefore, when the multi-layer coated polarizing layers 122 of the polarizing element 120 are made of the same material, an interface can still be observed between two adjacent coated polarizing layers 122. For example, when observing two adjacent coated polarizing layers 122 in contact with each other in the thickness direction of the panel 110, a discontinuous boundary between the neat arrangement and the unneat arrangement of the polarizing layer material can be observed, which can be used to determine the interface between two adjacent coated polarizing layers 122, but not limited to this method.

[0031] When fabricating each layer of the coated polarizer layer 122, a fixed coating direction can be adopted, that is, the relative relationship between the coating direction and the positioning of the panel 110 is fixed. In this way, the multiple layers of the coated polarizer layer 122 that make up the polarizing element 120 can have absorption axes in the same direction to provide a consistent polarization direction, but it is not limited to this. In some embodiments, the manufacturing method of the polarizing element 130 is substantially the same as that of the polarizing element 120, so it will not be repeated here. In some embodiments, when fabricating the multiple layers of the coated polarizer layer 132 of the polarizing element 130, the coating direction can be different from the coating direction used for fabricating the coated polarizer layer 122. In some embodiments, the polarization direction provided by the polarizing element 130 can be different from the polarization direction provided by the polarizing element 120. In some embodiments, the polarization direction provided by the polarizing element 130 can be substantially perpendicular to the polarization direction provided by the polarizing element 120, but it is not limited to this. In other words, the direction of the absorption axis of the polarizing element 130 can be different from the direction of the absorption axis of the polarizing element 120. In some embodiments, the absorption axis of the polarizing element 130 can be substantially perpendicular to the absorption axis of the polarizing element 120. In some embodiments, the polarizing element 120 and / or the polarizing element 130 are fabricated on the panel 110 by coating, which can reduce the manufacturing cost.

[0032] In some embodiments, the panel 110 is a non-self-emitting display panel, and the electronic device 100 may include a light source module (not shown). The light source module may be located on one side of the panel 110. Before the light emitted by the light source module enters the panel 110, it will first pass through one of the polarizing elements 130 and 120, and after the light emitted by the light source module passes through the panel 110, it will pass through the other of the polarizing elements 130 and 120 before being provided to the user (viewer). Here, an example is given where the light emitted by the light source module sequentially passes through the polarizing element 130, the panel 110, and the polarizing element 120. The light ray L0 can be converted into a first polarized light L1 after passing through the polarizing element 130, which, for example, has linear polarization in a first direction, and the first direction is the polarization direction provided by the polarizing element 130. The first polarized light L1 can be converted into a second polarized light L2 after passing through the panel 110, which has linear polarization in a second direction. Then, the second polarized light L2 can be converted into a third polarized light L3 after passing through the polarizing element 120, which has linear polarization in a third direction, and the third direction is the polarization direction provided by the polarizing element 120. In some embodiments, the polarization directions of the first polarized light L1 and the third polarized light L3 may be perpendicular to each other. In some embodiments, according to the design requirements, the panel 110 may or may not change the polarization direction of the first polarized light L1. In some cases, if the panel 110 does not change the polarization direction of the first polarized light L1, that is, the polarization directions of the first polarized light L1 and the second polarized light L2 are the same, at this time, after the second polarized light L2 enters the polarizing element 120, most of the second polarized light L2 may be absorbed by the polarizing element 120 and cannot pass through the polarizing element 120, thereby, for example, displaying a dark state image (such as a black image). In some cases, if the panel 110 can change the polarization direction of the first polarized light L1 so that the first polarized light L1 is converted into a second polarized light L2 with a different polarization direction, at least part of the second polarized light L2 can pass through the polarizing element 120 after entering the polarizing element 120, and a corresponding bright state image is presented.

[0033] In this embodiment, the polarizing element 120 includes at least two layers of coated polarizing layers 122, and the polarization efficiency of the polarizing element 120 can be improved by the at least two layers of coated polarizing layers 122. For example, in an experiment, when a single-layer coated polarizing layer 122 is used, the polarization efficiency that can be provided is about 99.5, while when two layers of coated polarizing layers 122 are used, the polarization efficiency that can be provided is about 99.8, but it is not limited thereto. Therefore, in response to different design specifications, the number of coated polarizing layers 122 of the polarizing element 120 can be adjusted, not limited to the number of layers disclosed in the drawings of this case. In addition, the thickness of a single-layer coated polarizing layer 122 is 0.6 micrometers to 1 micrometer in some embodiments, but it is not limited thereto.

[0034] Figure 2 Schematic diagram of an electronic device according to an embodiment of the present disclosure.Figure 2 The electronic device 200 includes a panel 110 and a polarizing element 220, wherein the polarizing element 220 includes a multi-layer coated polarizing layer 122 and at least one separating layer 222. For example, the polarizing element 220 includes a multi-layer coated polarizing layer 122 and a multi-layer separating layer 222. Here, the panel 110 and the multi-layer coated polarizing layer 122 are substantially similar to the corresponding components in the foregoing embodiment, and the manufacturing method and configuration relationship thereof can be referred to the description of the foregoing embodiment and will not be repeated here. In this embodiment, the polarizing element 220 is disposed on the first side 110A of the panel 110. In other embodiments, a polarizing film or Figure 1 a polarizing element 130 may be further disposed on the second side 110B of the panel 110 to achieve the required optical effect. Specifically, the difference between the polarizing element 220 and the polarizing element 120 is that the polarizing element 220 further includes at least one separating layer 222, and the separating layer 222 can be disposed between two of the coated polarizing layers 122 in the multi-layer coated polarizing layer 122, and the separating layer 222 has no polarization property. In other words, the separating layer 222 can separate two adjacent coated polarizing layers 122. In this embodiment, the coated polarizing layer 122 closest to the panel 110 can selectively contact the panel 110, but not limited thereto. In other embodiments, other layers may be further inserted between the coated polarizing layer 122 closest to the panel 110 and the panel 110.

[0035] The steps of manufacturing the polarizing element 220 may include coating and curing the polarizing layer material in the foregoing embodiment, and further forming the separating layer 222 after forming each coated polarizing layer 122 and then making the next coated polarizing layer 122, but not limited thereto. The method of forming the separating layer 222 may include a coating method, a deposition method or a similar film-forming method, but not limited thereto. In some embodiments, the separating layer 222 may have optical isotropy and no polarization property. Thus, the coated polarizing layers 122 on both sides of each separating layer 222 may have substantially the same polarization direction. In some embodiments, the separating layer 222 may have a phase delay, and the coated polarizing layers 122 on both sides of the separating layer 222 may have the same or different polarization directions in cooperation with the phase delay of the separating layer 222. In some embodiments, the separating layer 222 may have viscosity, which is beneficial to firmly attaching the coated polarizing layers 122 on both sides of each separating layer 222 to the separating layer 222, but not limited thereto. In some embodiments, the material of the separating layer 220 may include an inorganic material, an organic material or a combination of the above. For example, the material of the separating layer 220 may include silicon nitride, a photoresist material, a resin material, a polymer material, an optical adhesive or other similar light-transmitting or transparent materials.

[0036] Figure 3 It is a schematic diagram of an electronic device according to an embodiment of the present disclosure. Figure 3The electronic device 300 includes a panel 110 and a polarizing element 320. The polarizing element 320 includes a multi-layer coated polarizing layer 122 and a multi-layer separator layer 322. Here, the panel 110 and the multi-layer coated polarizing layer 122 are substantially similar to the corresponding components of the foregoing embodiments. The manufacturing method and the configuration relationship thereof may refer to the description of the foregoing embodiments and will not be repeated herein. In this embodiment, the polarizing element 320 is disposed on the first side 110A of the panel 110. In other embodiments, a polarizing film or Figure 1 a polarizing element 130 may be further disposed on the second side 110B of the panel 110 to achieve the desired optical effect.

[0037] In this embodiment, the difference between the polarizing element 320 and the polarizing element 120 is that the polarizing element 320 further includes a separator layer 322. The separator layer 322 is disposed between the multi-layer coated polarizing layers 122 and the separator layer 322 is non-polarizing. Specifically, the separator layer 322 may include a plurality of separator sub-layers 322A and 322B. In this embodiment, the separator sub-layer 322A may include a protective layer, and the separator sub-layer 322B may include an adhesive layer. The separator sub-layer 322B is used to adhere the separator sub-layer 322A to one of the coated polarizing layers 122, but is not limited thereto. Therefore, each separator sub-layer 322B is located between one separator sub-layer 322A and one of the coated polarizing layers 122, but is not limited thereto. In other embodiments (not shown), the separator layer 322 may include a plurality of separator sub-layers 322A and a separator sub-layer 322B. Two separator sub-layers 322B may be located on both sides of the separator sub-layer 322A, for example.

[0038] In some embodiments, the manufacturing method of the electronic device 300 includes first forming the first (closest to the panel 110) coated polarizing layer 122 on the panel 110 by the coating method described in the Figure 1 embodiment, then attaching the separator sub-layer 322A (protective layer) to the panel 110 through the separator sub-layer 322B (adhesive layer). Then, the second coated polarizing layer 122 is formed on the separator sub-layer 322A by the coating method described in the Figure 1 embodiment, and another separator sub-layer 322A is attached to the panel 110 through the separator sub-layer 322B. Repeating the above steps can complete the polarizing element 320, but is not limited thereto. In some embodiments, the separator sub-layer 322A is, for example, a pre-fabricated film layer. For example, the separator sub-layer 322A may include a formed thin film, glass, etc. Therefore, the separator sub-layer 322A can be adhered to the coated polarizing layer 122 by the separator sub-layer 322B, rather than being directly fabricated on the panel 110. In some embodiments, the separator sub-layer 322B may include a sticky and transparent optical adhesive, but is not limited thereto. In some embodiments, the polarizing element 320 can be applied to Figure 1to replace the polarizing element 120 or 130 in the electronic device 100.

[0039] Figure 4 Schematic diagram of an electronic device according to an embodiment of the present disclosure. Figure 4 The electronic device 400 includes a panel 110 and a polarizing element 420. The polarizing element 420 may include a multi-layer coated polarizing layer 122 and a multi-layer spacer layer 422. Here, the panel 110 and the multi-layer coated polarizing layer 122 are substantially similar to the corresponding components in the foregoing embodiments, and the manufacturing method and the configuration relationship thereof may refer to the description in the foregoing embodiments and will not be repeated herein.

[0040] In this embodiment, the polarizing element 420 may be stacked by a plurality of polarizing units 420U. Each polarizing unit 420U may include a coated polarizing layer 122, a spacer sub-layer 422A, and / or a spacer sub-layer 422B. The spacer sub-layer 422A may be a formed thin film, glass, etc. The coated polarizing layer 122 may be formed on the spacer sub-layer 422A by Figure 1 the coating method described above. The spacer sub-layer 422B may be an adhesive layer having adhesiveness, such as an optical adhesive, and the spacer sub-layer 422B may be formed on the coated polarizing layer 122. The polarizing unit 420U may be attached to the panel 110 or other polarizing units 420U through the spacer sub-layer 422B to form the polarizing element 420, but not limited thereto. That is to say, the coated polarizing layer 122 may be manufactured in advance and then attached to the panel 110 by an attachment method. In other words, the coated polarizing layer 122 in the polarizing element 420, for example, does not contact the panel 110.

[0041] In the polarizing element 420, one spacer sub-layer 422A and one spacer sub-layer 422B may be disposed between two adjacent coated polarizing layers 122 to form one spacer layer 422, but not limited thereto. However, the spacer sub-layer 422A and the spacer sub-layer 422B that are in contact with each other to form the spacer layer 422 may belong to different polarizing units 420U. For example, when the polarizing unit 420U closest to the panel 110 is defined as the first polarizing unit 420U and the polarizing unit 420B on the first polarizing unit 420U is defined as the second polarizing unit 420U, the spacer sub-layer 422B of the first polarizing unit 420U may contact the panel 110, and the spacer sub-layer 422A of the first polarizing unit 420U will be combined with the spacer sub-layer 422B of the second polarizing unit 420U to form the spacer layer 420 between two adjacent coated polarizing layers 122. In this embodiment, the spacer layer 420 may not have polarization. Specifically, neither the spacer sub-layer 422A nor the spacer sub-layer 422B has polarization. Therefore, the light passing through the spacer sub-layer 422A and / or the spacer sub-layer 422B will not significantly change the polarization state. Thus, the polarization effect of the polarizing element 420 is mainly determined by the multi-layer coated polarizing layer 122.

[0042] Figure 5 Schematic diagram of an electronic device according to an embodiment of the present disclosure. Figure 5 The electronic device 500 includes a panel 110 and a polarizing element 520. The electronic device 500 is generally similar to the electronic device 400. Therefore, components represented by the same reference numerals in the two embodiments can be referred to each other, and will not be repeated here. The difference between the electronic device 500 and the electronic device 400 is that the polarizing element 520 includes a coating-type polarizing layer 122 that directly contacts the panel 110 in addition to the polarizing element 420. The manufacturing method of the coating-type polarizing layer 122 contacting the panel 110 can be referred to Figure 1 the description of the embodiment, and will not be repeated here.

[0043] Figure 6 and Figure 7 are schematic diagrams for explaining the optical function of the polarizing element in the embodiments of the present disclosure. Figure 6 shows adjacent two coating-type polarizing layers 610 and 620 in the polarizing element and a separation layer 630 between the adjacent two coating-type polarizing layers 610 and 620. The structure, material, arrangement mode, etc. of the coating-type polarizing layers 610 and 620 can be referred to the description of the coating-type polarizing layer 122 in the foregoing embodiments, and the structure, material, arrangement mode, etc. of the separation layer 630 can be referred to the description of the separation layers 222, 322 or 422 in the foregoing embodiments. In Figure 6 , the polarization direction P610 provided by the coating-type polarizing layer 610 and the polarization direction P620 provided by the coating-type polarizing layer 620 can be parallel to each other. In some embodiments, the separation layer 630 may not have polarization properties and may not have a phase delay. For example, the phase delay value of the separation layer 630 is approximately equal to 0 nanometers (or the error is, for example, 0 ± 20 nanometers), and the optical absorption axis directions of the two adjacent coating-type polarizing layers (such as the coating-type polarizing layers 610 and 620) are parallel to each other. Through the above design, the light passing through the coating-type polarizing layer 610 can have a polarization state parallel to the polarization direction P610. This polarized light still has a polarization state substantially parallel to the polarization direction P610 after passing through the separation layer 630 (without phase delay), and then enters the coating-type polarizing layer 620. Since the polarization direction P620 of the coating-type polarizing layer 620 is substantially parallel to the polarization direction P610, most of this polarized light can pass through the coating-type polarizing layer 620.

[0044] In some embodiments, the separation layer 630 may have a phase delay, and the phase delay value of the separation layer 630 is not 0 nanometers, and the optical absorption axis directions of the two adjacent coating-type polarizing layers 610 are parallel to each other or intersect each other.

[0045] For example, the polarization direction P610 provided by the coating-type polarizing layer 610 and the polarization direction P620 provided by the coating-type polarizing layer 620 can be substantially parallel. In addition, the separation layer 630 can have a phase delay (i.e., the phase delay value of the separation layer 630 is not 0 nanometers). In addition, the slow axis A630a of the separation layer 630 can be set to be substantially parallel to the polarization direction P610. In this way, the light passing through the coating-type polarizing layer 610 can still have a polarization state substantially parallel to the polarization direction P610 after passing through the separation layer 630, and most of this polarized light can pass through the coating-type polarizing layer 620 after passing through the separation layer 630 again.

[0046] In some embodiments, the polarization direction P610 provided by the coating-type polarizing layer 610 and the polarization direction P620 provided by the coating-type polarizing layer 620 can be substantially parallel. At the same time, the separation layer 630 can have a phase delay, and the phase delay value of the separation layer 630 is not 0 nanometers. In addition, the slow axis A630b of the separation layer 630 can be set to be substantially perpendicular to the polarization direction P610. In this way, the light passing through the coating-type polarizing layer 610 can still have a polarization state substantially parallel to the polarization direction P610 after passing through the separation layer 630, and most of this polarized light can pass through the coating-type polarizing layer 620 after passing through the separation layer 630 again.

[0047] In some embodiments, the separation layer 630 can have a phase delay, and the phase delay value of the separation layer 630 is an integer multiple (e.g., nλ, where n is an integer) of the wavelength (e.g., λ) of the incident light. At this time, the slow axis A630c of the separation layer 630 can intersect the polarization direction P610 at an angle θ1, and the angle θ is, for example, 45 degrees. In this way, the light passing through the coating-type polarizing layer 610 can have a polarization state substantially parallel to the polarization direction P610 after passing through the separation layer 630, and most of the light of this polarized light can pass through the coating-type polarizing layer 620 after passing through the separation layer 630.

[0048] Figure 7 The adjacent two coating-type polarizing layers 710 and 720 in the polarizing element and the separation layer 730 between the adjacent two coating-type polarizing layers 710 and 720 are presented. As Figure 7As shown, the polarization direction P710 provided by the coating type polarizing layer 710 and the polarization direction P720 provided by the coating type polarizing layer 720 can intersect each other. At this time, the separation layer 730 can have a phase delay, that is to say, the phase delay value of the separation layer 63 is not equal to 0 nanometers. For example, the polarization direction P710 and the polarization direction P720 can be perpendicular to each other, and the phase delay value of the separation layer 730 is one-half (for example, 1 / 2λ) of the wavelength of the incident light (for example, λ). At this time, the slow axis A730 of the separation layer 730 can intersect the polarization direction P610 at an angle θ2, and the angle θ2 is approximately 45 degrees. In this way, the light with the polarization direction P730 passing through the coating type polarizing layer 710 can be transformed into a polarization state substantially parallel to the polarization direction P720 after passing through the separation layer 730, and this polarized light can mostly pass through the coating type polarizing layer 720. Generally speaking, when the separation layer 630 or the separation layer 730 has optical directivity, by adjusting the orientation of the optical directivity of the separation layer (such as 630 or 730) and the polarization directions of two adjacent coating type polarizing layers, such as the coating type polarizing layer 610 (or 710) and the coating type polarizing layer 620 (or 720), it is possible to adjust that most of the light passing through the coating type polarizing layer 610 (or 710) can mostly pass through the coating type polarizing layer 620 (or 720) after passing through the separation layer 630 (or 730), so as to reduce the chance of light being blocked.
