TECHNICAL FIELD
[0001] The present invention relates to an electronic device, and more particularly, to an electronic device having a recognition pattern for position detection. BACKGROUND
[0002] With the rapid development of technology, electronic devices with touch sensing function have become increasingly popular. Although the existing electronic devices have developed capacitive touch sensing technology to allow finger touch, the touch accuracy is still not as good as that of a stylus. However, the existing electronic devices need to additionally configure a digitizer to detect the input of the stylus, thus increasing the thickness and cost of the electronic device, and the inflexibility of the digitizer further limits the application of the electronic device. SUMMARY
[0003] The purpose of the present invention is to provide an electronic device to reduce the thickness and cost of the electronic device, or to improve the application of the electronic device.
[0004] The present invention provides an electronic device including a substrate, a recognition pattern, a visible light shielding structure, a first color unit, and a second color unit. The recognition pattern is disposed on the substrate, wherein the recognition pattern receives invisible light. The visible light shielding structure is disposed on the recognition pattern, and the visible light shielding structure includes a first portion overlapping the recognition pattern. The first color unit and the second color unit are disposed on the substrate and overlap the first portion, wherein a transmittance of the first color unit for the invisible light is less than a transmittance of the second color unit for the invisible light. In a cross-sectional view, a first width of the first color unit is defined by a portion of the first color unit corresponding to the first portion, a second width of the second color unit is defined by a portion of the second color unit corresponding to the first portion, and the first width of the first color unit is less than the second width of the second color unit.
[0005] The present invention further provides an electronic device having a visible light shielding region. The electronic device includes a substrate, a recognition pattern, a first color unit, and a second color unit. The recognition pattern is disposed on the substrate in a portion of the visible light shielding region, wherein the recognition pattern receives invisible light. The first color unit and the second color unit are disposed on the substrate, wherein a transmittance of the first color unit for the invisible light is less than a transmittance of the second color unit for the invisible light. In a cross-sectional view, a first width of the first color unit is defined by a portion of the first color unit located in the portion of the visible light shielding region, a second width of the second color unit is defined by a portion of the second color unit located in the portion of the visible light shielding region, and the first width of the first color unit is less than the second width of the second color unit.
[0006] The present invention also provides an electronic device comprising a substrate, a sensing pattern, an identification pattern, a first insulating layer, and a light-shielding structure. The sensing pattern and the identification pattern are disposed on the substrate, wherein the identification pattern receives invisible light. The first insulating layer is disposed on the sensing pattern and the identification pattern. The light-shielding structure is disposed on the first insulating layer, and the light-shielding structure includes a first portion overlapping the identification pattern and a second portion overlapping the sensing pattern.
[0007] In the electronic device of the present invention, since a location information identification pattern is provided, the electronic device does not require an additional digitizer, thereby reducing the thickness and cost of the electronic device, or improving its flexibility and application. Furthermore, by providing a visible light blocking structure on the identification pattern to block visible light while allowing invisible light to pass through, the signal-to-noise ratio of the identification pattern can be improved, thereby increasing the accuracy of the detected identification pattern.

[0036] Please refer to Figure 1 The diagram shown is a cross-sectional schematic of an electronic device according to a first embodiment of the present invention. Figure 1As shown, the electronic device 1 may include a substrate 12, an identified pattern 14, a visible light shielding structure 16, a color unit 18, and a color unit 20. The substrate 12 may be a flexible substrate that is bendable, foldable, rollable, or stretchable. The substrate 12 may include, for example, polyimide (PI), polyethylene terephthalate (PET), polycarbonate (PC), polyethersulfone (PES), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), or polyarylate (PAR), other suitable materials, or combinations thereof, but is not limited thereto. In some embodiments, the substrate 12 may also be a rigid substrate, such as glass, ceramic, quartz, sapphire, acrylic, or other suitable materials.
[0037] A recognition pattern 14 is disposed on a substrate 12, wherein the recognition pattern 14 is capable of receiving invisible light. Furthermore, a visible light shielding structure 16 is disposed on the recognition pattern 14, and the visible light shielding structure 16 includes a first portion 16a that overlaps with the recognition pattern 14. In this invention, "overlapping" of one element with another element can mean that the element and the other element completely or partially overlap in the normal direction ND of the substrate 12. It should be noted that in this invention, the recognition pattern 14 can be detected by a touch device that generates invisible light. The touch device may include, for example, a stylus pen or other device capable of emitting invisible light. By recognizing the recognition pattern 14, the position of the detected recognition pattern 14 can be obtained / identified, thereby determining the position where the touch device approaches or touches the electronic device 1. For example, the recognition pattern 14 may be a pattern containing coordinate information or other types of positional information; by recognizing the recognition pattern 14, the coordinate information of the recognition pattern 14 in the electronic device 1 can be obtained. In this invention, the touch device is described using a stylus as an example, but it is not limited to this.
[0038] In one embodiment, the number of identification patterns 14 may be multiple and different from each other. For example, different identification patterns 14 may differ in shape, size, rotation angle, or other features, such that each identification pattern 14 can correspond to information at different locations. Therefore, by embedding the location information corresponding to the identification pattern 14 into the touch device or a device electrically connected to the touch device, the touch device can obtain the corresponding location information after identifying a specific identification pattern 14, thereby determining the location where the touch device approaches or touches the electronic device 1. In some embodiments, the number of identification patterns 14 may be at least one. In this invention, the identification pattern 14 can absorb and / or reflect invisible light after receiving it when irradiated by invisible light. The identification pattern 14 may, for example, include a shielding material that can block invisible light or an opening pattern that allows invisible light to pass through, the specific structure of which will be further described below.
[0039] The visible light shielding structure 16 has the property of shielding or blocking visible light while allowing invisible light to pass through. Therefore, by overlapping the first part 16a with the identification pattern 14, the influence of ambient light on the signal of the detected identification pattern 14 can be reduced or avoided, thereby improving the signal-to-noise ratio of the identification pattern 14 and improving the accuracy of the detected identification pattern 14.
[0040] exist Figure 1 In this embodiment, the visible light blocking structure 16 may be, for example, a black matrix. The visible light blocking structure 16 may have openings OP1, OP2, and OP3, and color units 18 and 20 may be respectively disposed in the corresponding openings OP1 and OP2. The visible light blocking structure 16 may, for example, include black organic and / or inorganic materials, wherein the organic materials may include, for example, photoresist materials, acrylic materials, silicon-based materials, epoxy-based materials, other suitable organic materials, or combinations thereof, but are not limited thereto. Acrylic materials may, for example, be polymethyl methacrylate (PMMA) or other suitable materials or combinations thereof.
[0041] In some embodiments, in a cross-sectional view, the width W1 of the first portion 16a overlapping the visible light shielding structure 16 and the identification pattern 14 may be greater than the width W2 of the identification pattern 14 to prevent the identification pattern 14 from affecting the image displayed by the electronic device 1. Widths W1 and W2 may, for example, be widths along the cross-sectional direction CD. In this document, the cross-sectional direction CD may refer to a direction perpendicular to the normal direction ND of the substrate 12. Furthermore, the “width” of an element in a direction may refer to the maximum width of the element in that direction. For example, when the widths of the first portion 16a are inconsistent along the cross-sectional direction CD, the width W1 of the first portion 16a may refer to the maximum width of the first portion 16a along the cross-sectional direction CD. Similarly, the width W2 of the identification pattern 14 may refer to its maximum width along the cross-sectional direction CD.
[0042] Color units 18 and 20 are disposed on the substrate 12 and overlap with the first portion 16a. In other words, color units 18 and 20 adjacent to the first portion 16a can extend onto the first portion 16a of the visible light shielding structure 16. Figure 1 In the middle, the opening OP1 of the color unit 18 and the opening OP2 of the color unit 20 can be located on both sides of the first part 16a, so the first part 16a can be located between the color unit 18 and the color unit 20.
[0043] exist Figure 1 In some embodiments, the visible light shielding structure 16 may further include a second portion 16b, separated from the first portion 16a, and the electronic device 1 may optionally include a color unit 22 disposed on the substrate 12 and in the opening OP3 corresponding to the visible light shielding structure 16. The color unit 20 and the color unit 22 may extend to the second portion 16b of the visible light shielding structure 16 and overlap with the second portion 16b.
[0044] For example, color unit 18, color unit 20, and color unit 22 can be green, red, and blue, respectively, to allow green light, red light, and blue light to pass through, but are not limited thereto. In some embodiments, color unit 18, color unit 20, and color unit 22 can also be blue, red, and green, or blue, green, and red, or other arrangements of red, blue, and green. In some embodiments, color unit 18, color unit 20, and color unit 22 are not limited to combinations of green, red, and blue, but can also be three other different colors that can be mixed to produce white.
[0045] Please refer to Figure 2 The diagram shows a visible light shielding structure and a transmittance spectrum of different color units according to an embodiment of the present invention. Figure 1 and Figure 2As shown, taking color unit 18, color unit 20, and color unit 22 as green, red, and blue respectively, curves C1, C2, and C3 represent the transmittance spectra of color unit 18, color unit 20, and color unit 22, respectively, while curve C4 represents the transmittance spectrum of the visible light blocking structure 16. From Figure 2 It is understood that the transmittance of the visible light blocking structure 16 to invisible light can be greater than the transmittance of any one of the color units 18, 20, and 22 to invisible light, thereby reducing the impact on the detection and recognition pattern 14. Conversely, one of the color units 18, 20, and 22 can block invisible light to reduce the impact of ambient light on the detection and recognition pattern 14. For example, when color units 18, 20, and 22 are green, red, and blue respectively, the transmittance of the visible light blocking structure 16 to invisible light can be greater than that of color unit 20, the transmittance of color unit 20 to invisible light can be greater than that of color unit 18, and the transmittance of color unit 18 to invisible light can be greater than that of color unit 22, but this is not limited to these limitations. The transmittance of the visible light blocking structure 16 to invisible light can, for example, be greater than 30%. In some embodiments, the transmittance of the visible light shielding structure 16 to invisible light may be greater than the transmittance of color unit 22 to invisible light, but less than the transmittance of color unit 20 and color unit 18 to invisible light, or may be greater than the transmittance of color unit 22 and color unit 18 to invisible light, but less than the transmittance of color unit 20 to invisible light. In some embodiments, the transmittance of the visible light shielding structure 16 to invisible light may be greater than twice the transmittance of any one of color unit 18, color unit 20, or color unit 22 to invisible light. For example, the transmittance of the visible light shielding structure 16 to invisible light may be greater than twice the transmittance of color unit 18, color unit 20, or color unit 22 to invisible light. In this invention, invisible light may be, for example, infrared light, ultraviolet light, or other invisible electromagnetic waves of other wavelengths. The wavelength B1 of infrared light may be, for example, 760 nanometers (nm) to 800 nm. The wavelength B2 of ultraviolet light may be, for example, 380 nm to 400 nm.
[0046] It should be noted that the transmittance spectra of the visible light shielding structure 16, color unit 18, color unit 20, and color unit 22 can be measured, for example, by measuring the transmittance spectra of the individual visible light shielding structure 16, color unit 18, color unit 20, and color unit 22, or by measuring the transmittance spectra of the portions of the composite layer structure (e.g., the upper plate Sub1 below) containing the visible light shielding structure 16, color unit 18, color unit 20, and color unit 22. The specific measurement methods will be described below.
[0047] Please continue to refer to this. Figure 1 In the cross-sectional view of electronic device 1, the width W3 of color unit 18 is defined by the portion of color unit 18 corresponding to the first part 16a, and the width W4 of color unit 20 is defined by the portion of color unit 20 corresponding to the first part 16a. Furthermore, the width W3 of color unit 18 is smaller than the width W4 of color unit 20. Since the transmittance of color unit 18 is less than that of color unit 20, the obstruction of invisible light by color unit 18 can be reduced by the width W3 being smaller than the width W4, thereby improving the signal-to-noise ratio of the recognition pattern 14. Here, the portion of color unit 18 (or color unit 20) corresponding to the first part 16a can refer to the portion of color unit 18 (or color unit 20) that overlaps with the first part 16a in the top view of electronic device 1, and its width W3 (or width W4) can refer to the maximum width of the portion corresponding to the first part 16a in the cross-sectional direction CD. In other words, in the cross-sectional view, color unit 20 is closer to the recognition pattern 14 than color unit 18. The comparison of "closeness" here may refer, for example, to the comparison of the overlapping area of the color unit and the identification pattern (e.g., the overlapping area of color unit 20 is greater than the overlapping area of color unit 18) or the distance between the center line of the color unit and the identification pattern. In this invention, the top view of the electronic device may be, for example, the electronic device viewed along a direction parallel to the normal direction ND of the substrate 12.
[0048] For example, in the first part 16a of the corresponding identification pattern 14, when the transmittance of color unit 20 is greater than that of color unit 18, the overlapping area of color unit 20 and the first part 16a can be greater than the overlapping area of color unit 18 and the first part 16a.
[0049] exist Figure 1 In some embodiments, in a top view, color unit 18 may be located outside the identification pattern 14, while color unit 20 may overlap the identification pattern 14, but is not limited thereto. In this document, "outside" another element in a top view means that the element does not overlap the other element in the top view. In some embodiments, color unit 18 and color unit 20 may both overlap or not overlap the identification pattern 14.
[0050] like Figure 1 As shown, when the second portion 16b does not overlap with the identification pattern 14, the transmittance of color unit 22 can be less than the transmittance of color unit 20, and the width of color unit 20 corresponding to the second portion 16b can be less than the width of color unit 22 corresponding to the second portion 16b, so as to reduce the amount of invisible light incident on the elements below the second portion 16b. In other words, in the cross-sectional view, color unit 22 can be closer to the identification pattern 14 than color unit 20, but is not limited thereto. In some embodiments, when the second portion 16b overlaps with the identification pattern 14, the transmittance of color unit 20 can be less than the transmittance of color unit 22, and the width of color unit 20 corresponding to the second portion 16b can be less than the width of color unit 22 corresponding to the second portion 16b.
[0051] exist Figure 1 In this embodiment, the portions of color unit 18 and color unit 20 that overlap with the first portion 16a may overlap with each other, and the portions of color unit 20 and color unit 22 that overlap with the first portion 16a may overlap with each other, but are not limited thereto. In some embodiments, the portions of color unit 18 and color unit 20 that overlap with the first portion 16a may not overlap with each other, and / or the portions of color unit 20 and color unit 22 that overlap with the second portion 16b may not overlap with each other.
[0052] like Figure 1 and Figure 2 As shown, since color units 18, 20, and 22 have different colors, one of them can reduce or block the light of the other two colors, thereby reducing the impact of ambient light on the contrast of the image displayed by the electronic device 1, in other words, achieving an anti-reflective effect. Color units 18, 20, and 22 can, for example, be color filters of different colors, which may include, for example, photoresist or other suitable filtering materials.
[0053] like Figure 1 As shown, the electronic device 1 may further include a sensing layer TL disposed between the visible light shielding structure 16 and the substrate 12, and the sensing layer TL may also be disposed between the color unit 18, color unit 20, and color unit 22 and the substrate 12. The sensing layer TL may include at least one sensing pattern (e.g., Figure 3 The sensing pattern 26 shown is used to form the sensing element. Figure 1In this embodiment, the identification pattern 14 may be disposed in the sensing layer TL. For example, the sensing pattern and the identification pattern 14 may be formed from the same metal layer M1, but are not limited thereto. The sensing layer TL may be used for touch sensing, biometric facial sensing, biometric fingerprint sensing, blood oxygen sensing, distance sensing, electromagnetic wave sensing, or other suitable sensing applications. The touch sensing element may be used, for example, to detect the location of a touch object touching or approaching the electronic device 1. The touch object may include, for example, a user's body part (e.g., a finger), a touch device, or other objects suitable for touch. The following uses a touch sensing element as an example, but is not limited thereto.
[0054] exist Figure 1 In this embodiment, the sensing layer TL may further include an insulating layer IN1 disposed on the sensing pattern and the identification pattern 14, and the visible light shielding structure 16 disposed on the insulating layer IN1. It should be noted that the insulating layer IN1 can separate the identification pattern 14 from the visible light shielding structure 16, thereby protecting the identification pattern 14 from damage during the patterning process of the visible light shielding structure 16. For example, the thickness T1 of the insulating layer IN1 may be greater than the thickness T3 of the metal layer M1.
[0055] Please refer to Figure 3 The diagram shown is a partial top view of an electronic device according to an embodiment of the present invention, wherein... Figure 1 Can be Figure 3 A sectional view along section line A-A', but not limited to this. For example... Figure 1 and Figure 3 As shown, the sensing layer TL may further include an insulating layer IN2 and a sensing bridge 24, disposed between the sensing pattern 26 and the substrate 12, with the insulating layer IN2 disposed between the sensing bridge 24 and the sensing pattern 26. The sensing bridge 24 may be formed, for example, by a metal layer M2. The metal layer M1 and / or the metal layer M2 may include, for example, copper or other suitable materials. The insulating layer IN1 and / or the insulating layer IN2 may include, for example, silicon nitride, silicon oxide, silicon oxynitride, or other suitable insulating materials.
[0056] exist Figure 3In one embodiment, the sensing pattern 26 may include, for example, a plurality of sensing pads 26a, a plurality of sensing bridges 26b, and a plurality of sensing pads 26c. Sensing bridges 24 may electrically connect adjacent sensing pads 26c arranged in a first direction D1 to form a plurality of sensing strings 28, and sensing bridges 26b may electrically connect adjacent sensing pads 26a arranged in a second direction D2 to form a plurality of sensing strings 30. In a top view, sensing bridges 24 may overlap with and be electrically insulated from sensing bridges 26b, allowing sensing strings 28 to span sensing strings 30 to form touch sensing elements. In this embodiment, sensing pads 26a may be directly connected to sensing bridges 26b, while sensing pads 26c may be electrically connected to sensing bridges 24 through a through-hole TH1, wherein the through-hole TH1 may, for example, penetrate through... Figure 1 The insulating layer IN2 shown is not limited to this. The structure of the touch sensing element of the present invention is not limited to this. Figure 3 The above is a limited representation and can be adjusted as needed. For example, the sensing bridge 24 can be formed by the metal layer M1, while the sensing pattern 26 can be formed by the metal layer M2.
[0057] In the top view, the sensing pattern 26 and the sensing bridge 24 may overlap with the visible light shielding structure 16, thereby reducing the visibility of the sensing pattern 26 and the sensing bridge 24, or avoiding affecting the display effect of the electronic device 1. For example, the sensing pattern 26 and the sensing bridge 24 may have a grid-like structure, but are not limited to this. It should be noted that, in order to clearly show the sensing bridge 24 and the sensing pattern 26, Figure 3 The width of the grid lines used to represent the sensing bridge 24 is greater than the width of the grid lines used to represent the sensing pattern 26. However, the width of the sensing bridge 24 can actually be the same as or different from the width of the sensing pattern 26, depending on the requirements, and is not limited to this. Figure 3 As shown.
[0058] In some embodiments, the identification pattern 14 may also be formed from the same metal layer M2 as the sensing bridge 24, or the identification pattern 14 may be formed from other suitable film layers different from the sensing layer TL. In some embodiments, such as Figure 3 As shown, the identification pattern 14a may be, for example, an opening pattern of the sensing pattern 26 to allow invisible light to pass through, while the sensing pattern 26 may reflect invisible light, thus allowing the touch device to detect the identification pattern 14a. In some embodiments, the identification pattern 14b may be a combination of multiple identification patterns 14a, but is not limited thereto. In some embodiments, the electronic device 1 may include an identification pattern 14 capable of reflecting invisible light and / or identification patterns 14a and / or identification pattern 14b that allow invisible light to pass through. The identification pattern referred to below is... Figure 3 Taking the identification pattern 14, which can reflect invisible light, as an example, as an illustration, but... Figure 3 The identification pattern 14a or identification pattern 14b may also be applied to any of the above or below embodiments.
[0059] like Figure 1 and Figure 3 As shown, the thickness T1 of the insulating layer IN1 can be greater than the thickness T2 of the insulating layer IN2. In some embodiments, the thickness T3 of the metal layer M1 can be greater than the thickness T4 of the metal layer M2, so that the identification pattern 14 and the sensing pattern 26 can be bent or prevented from being damaged during manufacturing. In other words, the thickness T3 of the identification pattern 14 formed by the metal layer M1 can be greater than the thickness T4 of the sensing bridge 24 formed by the metal layer M2. For example, the ratio of thickness T4 to thickness T3 can be greater than or equal to 0.6 and less than 1 (i.e., 0.6 ≤ the ratio of thickness T4 to thickness T3 < 1). In addition, the thickness T2 of the insulating layer IN2 can also be greater than the thickness T4 of the metal layer M2. In some embodiments, when the identification pattern 14 and the sensing pattern 26 are formed by different metal layers, the thickness of the identification pattern 14 can be greater than the thickness of the sensing pattern, but is not limited thereto.
[0060] exist Figure 1 In some embodiments, the electronic device 1 may further include a protective layer 32 and a cover layer 34, sequentially disposed on the visible light shielding structure 16, color unit 18, color unit 20, and color unit 22.

The cover layer 34 can be attached to the protective layer 32 via an adhesive layer AL. The cover layer 34 may, for example, include a combination of ultra-thin glass (UTG) and PET, or other suitable materials. The upper surface of the cover layer 34 away from the protective layer 32 may, for example, serve as the outer surface of the electronic device 1 for displaying images and / or for contact with a touch object. In some embodiments, a hard coating layer may be selectively disposed on the cover layer 34 (e.g., Figure 14 The hardened film layer 52 shown.

For example, the display layer DL may also include an insulating layer IN3 disposed on the electrode E1, and the insulating layer IN3 has multiple openings OP4 corresponding to the electrode E1. The light-emitting layers EL may be disposed in the corresponding openings OP4, and the electrode E2 may be disposed on the light-emitting layer EL. Figure 1 In this process, electrodes E2 can be interconnected to form the same conductive layer CL1, but are not limited to this. The insulating layer IN3 may have a light-shielding effect to prevent light from the light-emitting element 36 from mixing. The insulating layer IN3 may be referred to as the pixel definition layer and may include organic or inorganic materials.

[0064] exist Figure 1In the embodiments, the light-emitting element 36 may include a first light-emitting element 36a, a second light-emitting element 36b, and a third light-emitting element 36c, which are used to generate light of different colors, and the first light-emitting element 36a, the second light-emitting element 36b, and the third light-emitting element 36c may correspond to color unit 18, color unit 20, and color unit 22, respectively. For example, the first light-emitting element 36a, the second light-emitting element 36b, and the third light-emitting element 36c may be used to generate light of the colors corresponding to color unit 18, color unit 20, and color unit 22, such as generating green light, red light, and blue light, respectively. In the top view of the electronic device 1, openings OP1, OP2, and OP3 may overlap the first light-emitting element 36a, the second light-emitting element 36b, and the third light-emitting element 36c, respectively, but are not limited thereto.
[0065] like Figure 3 As shown in the top view, the first light-emitting element 36a, the second light-emitting element 36b, and the third light-emitting element 36c can be respectively disposed in the grid structure of the sensing pattern 26 and the sensing bridge 24, but are not limited thereto. In this embodiment, the first light-emitting element 36a, the second light-emitting element 36b, and the third light-emitting element 36c can be arranged, for example, in an array, and a row of second light-emitting elements 36b can be disposed between each row of first light-emitting elements 36a and each row of third light-emitting elements 36b. In other words, the first light-emitting element 36a is not adjacent to the third light-emitting element 36c, but is not limited thereto. The second light-emitting elements 36b in each row can be staggered with the first light-emitting elements 36a and the third light-emitting elements 36b in each row, but the arrangement of the light-emitting elements 36 in this invention is not limited thereto. In some embodiments, the arrangement of the first light-emitting element 36a, the second light-emitting element 36b, and the third light-emitting element 36c can also be adjusted as needed.
[0066] like Figure 1 As shown, circuit layer 38 may include signal lines, an insulating layer, active components, and / or passive components. Active components may include, for example, thin-film transistors or other suitable transistors, but are not limited thereto. Signal lines may include, for example, data lines, scan lines, common lines, or other required signal lines. Figure 1 In some embodiments, circuit layer 38 may include a plurality of transistors 38T, wherein transistors 38T may be electrically connected to corresponding light-emitting elements 36 and serve as driving elements and / or switching elements of light-emitting elements 36, but are not limited thereto. Circuit layer 38 may include at least one semiconductor layer SEM, multiple insulating layers IN4, and multiple conductive layers CL2 to form transistors 38T, signal lines, traces, capacitors, electrodes, and / or other circuit elements. Figure 1In some embodiments, transistor 38T may be, for example, a top-gate thin-film transistor, but is not limited thereto. In some embodiments, transistor 38T may be other types of thin-film transistors, such as a bottom-gate thin-film transistor.
[0067] like Figure 1 As shown, the display layer DL may further include a protective layer 40 disposed between the light-emitting element 36 and the sensing layer TL to reduce the possibility of damage to the light-emitting element 36 caused by moisture or oxygen. The protective layer 40 may, for example, comprise a stack or multiple layers of inorganic material layers consisting of at least one inorganic material layer and at least one organic material layer; the invention is not limited thereto. The inorganic material layers may, for example, comprise silicon nitride, silicon oxide, silicon oxynitride, aluminum oxide, or other suitable protective materials, or any combination of the aforementioned inorganic materials, but are not limited thereto. Different inorganic material layers may comprise the same material or different materials. The organic material layers may have the effect of planarizing the upper surface, for example, comprising resin or other suitable materials, but are not limited thereto.
[0068] In some embodiments, when the substrate 12 includes a flexible substrate, the electronic device 1 may optionally include a buffer layer BL disposed between the substrate 12 and the circuit layer 38 to reduce the influence of moisture and / or oxygen on the circuit layer 38 and / or the light-emitting layer EL. The buffer layer BL may include, for example, silicon nitride, silicon oxide, silicon oxynitride, or other suitable insulating materials.
[0069] It should be noted that when measuring the transmittance spectrum of the visible light shielding structure 16, color unit 18, color unit 20, and color unit 22, the measurement can be performed by removing part of the stacked layers of the electronic device 1 while retaining part of the composite layer structure. In other words, the transmittance of the visible light shielding structure 16, color unit 18, color unit 20, and color unit 22 in this paper can also be, for example, the transmittance of the portion of the composite layer structure corresponding to the visible light shielding structure 16, color unit 18, color unit 20, and color unit 22. For example, the electronic device 1 may include an upper board Sub1 and a lower board Sub2, wherein the upper board Sub1 may include a sensing layer TL, a visible light shielding structure 16, color unit 18, color unit 20, and color unit 22, a protective layer 32, an adhesive layer AL, and a cover layer 34, while the lower board Sub2 may include a display layer DL, a buffer layer BL, and a substrate 12. Furthermore, when partially removing the laminated electronic device 1, the portion of electronic device 1 torn off may be, for example, the lower plate Sub2, while the remaining composite layer structure may be, for example, the upper plate Sub1, but is not limited thereto. Figure 1 As shown, the transmittance spectrum of the visible light shielding structure 16 can be measured from one side of the upper plate Sub1 (e.g., Figure 1 The upper plate Sub1 shown is illuminated with a light beam L, and the light beam L is aligned with the position on the upper plate Sub1 where the visible light shielding structure 16 and the identification pattern 14 overlap. Then, on the other side (e.g.)Figure 1 The intensity of light beam L is measured on the upper side of the upper plate Sub1 shown, and the wavelength of the beam L is adjusted to measure the transmittance spectrum of the visible light shielding structure 16 in a specific wavelength band. The specific wavelength band may be, for example, [missing information - likely a specific wavelength band]. Figure 2 The wavelength range is 380 nm to 780 nm. The spot size of the light beam L can be, for example, 10 μm × 10 μm. When measuring the transmittance spectrum of the visible light shielding structure 16, the area illuminated by the light beam L can be, for example, region R1 of the upper plate Sub1, which overlaps with the first portion 16a. Similarly, the transmittance spectrum of the color unit can be measured in a similar manner to that of the visible light shielding structure 16. Taking color unit 18 as an example, the light beam L can be aligned with the position of the upper plate Sub1 corresponding to the color unit 18 to measure the transmittance spectrum of the color unit 18 in a specific wavelength band. When measuring the transmittance spectrum of the color unit 18, the area illuminated by the light beam L can be, for example, region R2 of the upper plate Sub1, which overlaps with the color unit 18. The top-view areas of region R1 and region R2 can be the same. Figure 1 As can be seen, since regions R1 and R2 of the upper plate Sub1 both include the same insulating layer IN1, insulating layer IN2, protective layer 32, adhesive layer AL, and cover layer 34, the transmittance difference measured between regions R1 and R2 can still be considered as the transmittance difference between the visible light shielding structure 16 and the color unit 18. The transmittance spectra of color units 20 and 22 can be obtained using the same measurement method as for the transmittance spectrum of color unit 18, and therefore will not be elaborated upon here. Figure 2 The transmittance spectrum shown may be, for example, the transmittance spectrum measured by irradiating the upper plate Sub1. In some embodiments, in a top view, the width through which invisible light can pass through the visible light shielding structure 16 may be greater than the maximum width of one of the color units 18, 20, and 22.
[0070] The electronic device of the present invention is not limited to the above embodiments and may have other embodiments or variations. For the sake of simplicity, the same reference numerals will be used to label the same elements as in the above embodiments for other embodiments and variations. To clearly illustrate the other embodiments and variations, the differences between the other embodiments and variations and the above embodiments will be highlighted below, and repeated parts will not be described again.
[0071] Please refer to Figure 4 The diagram shown is a cross-sectional schematic of an electronic device according to a variation of the first embodiment of the present invention. Figure 4As shown, in the electronic device 1a provided in this variant embodiment, in a cross-sectional view, the center line L1 of the identification pattern 14 and the center line L2 of the first portion 16a may be separated from each other and not aligned, that is, the distance d between the center lines L1 and L2 in the cross-sectional view may be greater than zero. The center line may, for example, be a straight line passing through the center point of the element and parallel to the normal direction ND. In other words, in a top view, the identification pattern 14 may be closer to one of the color units 18 and 20 and farther from the other. When the transmittance of the color unit 18 to invisible light is less than that of the color unit 20 to invisible light, the identification pattern 14 may be closer to the color unit 20 with the greater transmittance to improve the signal-to-noise ratio of the detection identification pattern 14. For example, the distance d may be less than or equal to half the width of the first portion 16a in the cross-sectional direction CD.
[0072] exist Figure 4 In some embodiments, the first portion 16a overlapping the identification pattern 14 and the second portion 16b not overlapping the identification pattern 14 have different thicknesses H1 and H2, respectively. Thickness H1 may be, for example, smaller than thickness H2, such that the transmittance of the first portion 16a to invisible light is greater than that of the second portion 16b to invisible light, thereby improving the signal-to-noise ratio of the identification pattern 14. In some embodiments, the difference between thickness H1 and thickness H2 may also be applied to any of the embodiments described above or below.
[0073] In some embodiments, the color unit 18 and color unit 20 extending onto the first portion 16a may not overlap, meaning that a portion of the first portion 16a may not be covered by the color unit 18 and color unit 20. This reduces the impact of the color unit 18 and color unit 20 on the intensity of invisible light, thereby improving the signal-to-noise ratio of the recognition pattern 14. Other portions of the electronic device 1a in this variant embodiment may be similar to or identical to... Figure 1 The electronic device 1 is not described in detail here.
[0074] Please refer to Figure 5 The diagram shown is a cross-sectional schematic of an electronic device according to another variation of the first embodiment of the present invention. Figure 5 As shown, in the electronic device 1b provided in this variant embodiment, the light-emitting element 36 may include an inorganic light-emitting diode. In this case, the display layer DL may include a plurality of pads BP1 and a plurality of pads BP2, and the opening OP4 of the insulating layer IN3 may correspond to one pad BP1 and one pad BP2, such that the two pads of the light-emitting element 36 may be respectively bonded to pads BP1 and BP2. In this embodiment, the identification pattern 14 may be located between the pad BP2 corresponding to the second light-emitting element 36b and the pad BP1 corresponding to the first light-emitting element 36a in the top view, but is not limited thereto.
[0075] existFigure 5 In this embodiment, the display layer DL may optionally include an encapsulation layer 42 disposed on the light-emitting element 36 and the insulating layer IN3 to protect the light-emitting element 36. The encapsulation layer 42 may, for example, include an encapsulation material or other suitable material. Furthermore, a protective layer 40 may be disposed on the encapsulation layer 42 to provide a flat upper surface to facilitate the formation of a high-quality sensing layer TL.
[0076] exist Figure 5 In some embodiments, the circuit layer 38 may have multiple openings OP5, such that the circuit layer 38 may include multiple island structures 38a spaced apart from each other. In this case, the display layer DL may also include an insulating layer IN5 disposed on the island structures 38a and in the openings OP5 to improve the flexibility of the circuit layer 38. The openings OP5 may, for example, not overlap with the light-emitting element 36. In some embodiments, the insulating layer IN5 may, for example, comprise a single-layer structure or a multi-layer structure, and may include any suitable organic or inorganic material.
[0077] In this embodiment, the color unit 18 extending onto the first portion 16a and the color unit 20 may not overlap, and the color unit 20 extending onto the second portion 16b and the color unit 22 may also not overlap, but are not limited thereto. In some embodiments, Figure 5 The structure and relationship of color unit 18, color unit 20, and color unit 22 can also adopt any of the above or following embodiments. Other parts of the electronic device 1b in this variation embodiment can be similar to or the same as those described. Figure 1 The electronic device 1 is not described in detail here.
[0078] Please refer to Figure 6 The diagram shown is a cross-sectional schematic of an electronic device according to a second embodiment of the present invention. Figure 6 As shown, the electronic device 2 provided in this embodiment may include a light-shielding structure 106 instead of... Figure 1 The visible light shielding structure 16 is shown. Specifically, the electronic device 2 of this embodiment may include a substrate 12, a sensing pattern 26, an identification pattern 14, an insulating layer IN2, and a light shielding pattern 16, wherein the light shielding structure 106 is disposed on the insulating layer IN2, and the light shielding structure 106 includes a first portion 106a overlapping the identification pattern 14 and a second portion 106b overlapping the sensing pattern 26.
[0079] exist Figure 6In this embodiment, the light-shielding structure 106 may be a multi-layered structure, and the number of layers in the first portion 106a may be different from the number of layers in the second portion 106b. For example, the number of layers in the first portion 106a may be less than the number of layers in the second portion 106b, and the thickness H1 of the first portion 106a may be less than the thickness H2 of the second portion 106b. For example, the light-shielding structure 106 may include a first layer 1061 and a second layer 1062, sequentially disposed on the sensing layer TL, wherein a portion of the first layer 1061 and a portion of the second layer 1062 may form the second portion 106b, and the first portion 106a is formed by a portion of the first layer 1061. In this embodiment, the transmittance of the first portion 106a for invisible light may be, for example, greater than 30%. In one embodiment, both the first layer 1061 and the second layer 1062 allow invisible light to pass through and block visible light from passing through. In this case, having more layers in the second portion 106b than in the first portion 106a can help the second portion 106b shield the sensing pattern 26, or it can help increase the intensity of invisible light passing through the first portion 106a, thereby improving the signal-to-noise ratio of the identification pattern 14. In some embodiments, when both the first layer 1061 and the second layer 1062 allow invisible light to pass through and block visible light from passing through, the number of layers in the first portion 106a can also be the same as the number of layers in the second portion 106b. For example, the first portion 106a may include a portion of the first layer 1061 and a portion of the second layer 1062. For example, the light-shielding structure 106 includes multiple visible light shielding structures as described in the above embodiments.
[0080] In another embodiment, the transmittance of the first layer 1061 of the first portion 106a to invisible light may be greater than the transmittance of the second layer 1062 of the second portion 106b to invisible light. For example, the first layer 1061 allows invisible light to pass through while blocking visible light, while the second layer 1062 blocks both invisible and visible light. Therefore, the ability of the second portion 106b to block invisible light is enhanced, thereby reducing the possibility that the sensing pattern 26 is illuminated by invisible light, and improving the signal-to-noise ratio of the identified pattern 14. In this case, the first portion 106a may not have the second layer 1062. Other parts of the electronic device 2 in this embodiment may be similar to or the same as the electronic device in any of the above embodiments, and therefore will not be described in detail here.
[0081] Please refer to Figure 7 The diagram shown is a cross-sectional schematic of an electronic device according to a third embodiment of the present invention. Figure 7 As shown, the electronic device 3 provided in this embodiment may have a visible light shielding region 16R, and it replaces... Figure 1The visible light shielding structure 16 is shown. The visible light shielding area 16R can be defined, for example, by a stack of multiple visible light shielding structures or a stack of multiple color units. Specifically, the electronic device 3 may include a substrate 12, an identification pattern 14, color units 18 and color units 20, wherein the identification pattern 14 is disposed on the substrate 12 in a portion PR1 of the visible light shielding area 16R. Figure 7 In this embodiment, the visible light shielding region 16R is illustrated by example of a stack of multiple color units, but is not limited thereto. Color units 18 and 20 can be disposed on the substrate 12 in the visible light shielding region 16R. The transmittance of color unit 18 to invisible light can be less than that of color unit 20 to invisible light, and the width W3 of color unit 18 is less than the width W4 of color unit 20. In a cross-sectional view, the width W3 of color unit 18 is defined by the portion of color unit 18 located in the portion PR1 of the visible light shielding region 16R, and the width W4 of color unit 20 is defined by the portion of color unit 20 located in the portion PR1 of the visible light shielding region 16R. In this embodiment, the width W1 of the visible light shielding region 16R can be greater than the width W2 of the identification pattern 14. Since the identification pattern 14 in this embodiment can be the same as or similar to that in the above embodiments, it will not be described in detail here.
[0082] exist Figure 7 In some embodiments, the identification pattern 14 may not overlap with the color unit 18 to reduce the impact of the low-transmittance color unit 18 on the detection of the identification pattern 14. The electronic device 3 may also include a color unit 22a disposed on the substrate 12, wherein the color units 18, 20, and 22a are different colors from each other, and at least a portion of the color unit 20 overlaps with at least a portion of the color unit 22a in a portion PR1 of the visible light blocking region 16R. The portion PR1 may be defined, for example, by the stacking of the color units 22a and 20, but is not limited thereto. In this embodiment, the colors of the color units 18, 20, and 22a may be blue, green, and red, respectively, but are not limited thereto. In some embodiments, the color unit 22a may also be replaced with... Figure 1 , Figure 4 or Figure 5 Visible light shielding structure 16 or Figure 6 The light-shielding structure 106 is not limited to this.
[0083] In some embodiments, color unit 18 may be separated from color unit 20 in a portion PR1 of the visible light shielding region 16R. In some embodiments, color unit 18 may overlap with or not overlap with color unit 20. In some embodiments, color unit 18 may also be disposed on color unit 22a, that is, color unit 22a is located between color unit 18 and substrate 12.
[0084] In some embodiments, the thickness T5 of at least a portion of color unit 20 may differ from the thickness T6 of at least a portion of color unit 22a. For example, when color unit 20 is green and color unit 22a is red, thickness T5 may be less than thickness T6 to improve the intensity of invisible light detected by the identification pattern 14. Hereinafter, the thickness of the color unit can be measured by measuring the thickness of the central region R3 of the color unit, where the central region R3 may be, for example, the overlapping area at two-thirds of the width of the color unit measured from its left edge and its right edge.
[0085] exist Figure 7 In some embodiments, the electronic device 3 may further include a color unit 22 and a sensing pattern 26 disposed on the substrate 12, wherein the color units 18, 20, and 22 are different colors from each other, and the sensing pattern 26 is disposed in another portion PR2 of the visible light blocking region 16R, and at least a portion of the color unit 20 overlaps with at least a portion of the color unit 22 in the portion PR2 of the visible light blocking region 16R. The portion PR2 of the visible light blocking region 16R may be defined, for example, by the overlapping portion of the color units 20 and 22. Figure 7 In some embodiments, color unit 20 may extend onto color unit 22 in a portion of PR2, but is not limited thereto. In some embodiments, color unit 20 may also be disposed between color unit 22 and sensing layer TL in a portion of PR2. In some embodiments, color unit 22a may have the same color as color unit 22 or may be formed from the same film layer, but is not limited thereto.
[0086] In some embodiments, the electronic device 3 may further include a color unit disposed in a portion of PR2, and the color unit may, for example, have the same color as color unit 18 or be formed from the same film layer. In this case, color unit 18 may be disposed on color unit 22a and its transmittance may be greater than that of color unit 20, and the identification pattern 14 may overlap color unit 18. For example, color unit 18, color unit 20, and color unit 22 may be green, blue, and red, respectively, but are not limited thereto.
[0087] In some embodiments, the identification pattern 14 may also be disposed on the substrate 12 in a portion of PR2 within the visible light shielding area 16R. In this case, color unit 20 and color unit 22 may be, for example, green and red or red and green. Furthermore, a majority of the color unit 18 located in the portion PR1 may selectively overlap with the color unit 20; for example, the width W3 of the color unit 18 may be close to or the same as the width W4 of the color unit 20, but is not limited thereto. In some embodiments, the identification pattern 14 may not overlap with the color unit 18 or may not be disposed in the portion PR1.
[0088] In some embodiments, the total thickness of the stacked portion of color unit 20 and color unit 22 on the identification pattern 14 may be less than the total thickness of the stacked portion of color unit 18, color unit 22a and color unit 20 on the sensing pattern 26. Other parts of the electronic device 2 in this embodiment may be similar to or the same as the electronic device in any of the above embodiments, and therefore will not be described in detail here.
[0089] Please refer to Figure 8 The diagram shown is a partial top view of the electronic device according to the fourth embodiment of the present invention. To clearly show the identification pattern 14, Figure 8 The display includes the light-emitting element 36, the corresponding color unit, the identification pattern 14, and the visible light blocking pattern 16, omitting other elements, but is not limited to this. For example... Figure 8 As shown, the identification pattern 14 of the electronic device 4 provided in this embodiment may include identification pattern 141, identification pattern 142, and identification pattern 143, each with different sizes. For example, the top view shape of identification pattern 141, identification pattern 142, and identification pattern 143 may be rectangular, and their widths in the first direction D1 or the second direction D2 may be different from each other. Alternatively, the widths of identification pattern 141, identification pattern 142, and identification pattern 143 may be different from each other in the first direction D1, and their widths in the second direction D2 may also be different from each other. In some embodiments, the identification pattern 14 may also have different shapes or rotation angles.
[0090] exist Figure 8 In some embodiments, color units 18, 20, and 22 may not overlap each other, and identification patterns 141, 142, and 143 may not overlap with color units 18, 20, and 22. In some embodiments, the width of identification patterns 141, 142, and 143 in a direction (e.g., a first direction D1 or a second direction D2) may be less than the width of the visible light shielding structure 16 in that direction.
[0091] In some embodiments, when color unit 20 is green and color unit 22 is red, color unit 20 and color unit 22 may be used as follows: Figure 7 In some embodiments, they overlap each other in the visible light shielding area, and in this case, the electronic device may not include a visible light shielding structure, but is not limited thereto.
[0092] Please refer to Figure 9 The diagram shown is a cross-sectional view of an electronic device according to a fifth embodiment of the present invention. To clearly show the identification pattern 14, Figure 9 The display includes the light-emitting element 36, the corresponding color unit, the identification pattern 14, and the visible light blocking pattern 16, omitting other elements, but is not limited to this. For example... Figure 9As shown, the identification pattern 14 of the electronic device 5 provided in this embodiment can surround at least one light-emitting element 36 in a top view. For example, the identification pattern 14 may include identification pattern 141, identification pattern 142, and identification pattern 143, each with a different rotation angle. For example, the top view shape of identification pattern 141, identification pattern 142, and identification pattern 143 may be a ring rectangle, and one side of identification pattern 141, one side of identification pattern 142, and one side of identification pattern 143 may not be parallel or perpendicular to each other, but is not limited thereto. In some embodiments, identification pattern 141, identification pattern 142, and identification pattern 143 may also have different sizes.
[0093] In some embodiments, when color unit 20 is green and color unit 22 is red, color unit 20 and color unit 22 may be used as follows: Figure 7 In some embodiments, they overlap each other in the visible light shielding area, and in this case, the electronic device may not include a visible light shielding structure, but is not limited thereto.
[0094] Please refer to Figure 10 and Figure 11 , Figure 10 The diagram shown is a partial top view of the electronic device according to the sixth embodiment of the present invention, and Figure 11 The image shows along Figure 10 A schematic cross-sectional view of section lines B-B' and C-C'. (See attached diagram.) Figure 10 and Figure 11 As shown, the electronic device 6 provided in this embodiment and Figure 1 The difference between electronic device 1 and electronic device 6 is that electronic device 6 may further include at least one light-shielding pattern SP disposed on at least one light-emitting element 36. Figure 10 In this embodiment, there may be multiple light-shielding patterns SP, and one light-shielding pattern SP may correspond to one light-emitting element 36, for example. The light-shielding pattern SP may have at least one opening OP6 to allow light from the corresponding light-emitting element 36 to pass through. It should be noted that since the light-shielding pattern SP may partially overlap with the light-emitting element 36 in a top view, it can block light with a large emission angle generated from the light-emitting element 36, thereby reducing the viewing angle of the image displayed by the light-emitting element 36 corresponding to the light-shielding pattern SP, achieving a narrow viewing angle effect. The light-shielding pattern SP may, for example, be formed from the same metal layer M1 as the sensing pattern 26.
[0095] exist Figure 10 In some embodiments, the number of openings OP6 in the light-shielding pattern SP can be multiple, and multiple openings OP6 can overlap with a corresponding light-emitting element 36, but are not limited thereto. In some embodiments, one opening OP6 of one light-shielding pattern SP can correspond to one light-emitting element 36.
[0096] It is worth noting that the light-shielding pattern SP may include an identification pattern 14, such that the identification pattern 14 can be integrated into the light-shielding pattern SP, thereby saving the thickness of the electronic device 6. For example, the identification pattern 14 may include notches, openings, chamfers, bevels, or other suitable microstructures of the light-shielding pattern SP. The notches of different identification patterns 14 may, for example, face different directions. The number of notches of different identification patterns 14 may, for example, be different. In some embodiments, the light-shielding pattern SP may have multiple identification patterns 14, each corresponding to a light-emitting element 36. For example, the notches of different identification patterns 14 may each overlap a light-emitting element 36. In some embodiments, the openings of different identification patterns 14 may have different shapes, such as rectangular, cross-shaped, or other suitable shapes. Alternatively, the bevels of different identification patterns 14 may, for example, correspond to different sides of the light-shielding pattern SP. The variations of the identification pattern 14 of the present invention are not limited to the above. The identification pattern 14 may not overlap with the light-emitting element 36 in a top view.
[0097] Furthermore, in Figure 10 and Figure 11 In some embodiments, the electronic device 6 may include, for example, a plurality of first pixels PX1 and a plurality of second pixels PX2, wherein the second pixels PX2 may include a light-shielding pattern SP, while the first pixels PX1 do not include the light-shielding pattern SP. Figure 10 As shown, the first pixel PX1 and the second pixel PX2 may each include at least three light-emitting elements 36 that produce different colors, such that the light-emitting elements 36 of different colors can each serve as sub-pixels. In this case, by turning on the first pixel PX1 and turning off the second pixel PX2, the electronic device 6 can display an image with a wide viewing angle, while by turning on the second pixel PX2 and turning off the first pixel PX1, the electronic device 6 can display an image with a narrow viewing angle. In this embodiment, the first pixel PX1 and the second pixel PX2 may be arranged in a staggered manner, but are not limited to this.
[0098] In addition, such as Figure 11 As shown, both the first pixel PX1 and the second pixel PX2 may include a portion of the circuit layer 38, a portion of the display layer DL, a portion of the sensing layer TL, a visible light shielding structure 16, color units 18, 20, and 22, a portion of the protective layer 32, a portion of the adhesive layer AL, and a portion of the cover layer 34. In this embodiment, color units 18 and 20 disposed on the first portion 16a of the visible light shielding structure 16 may not overlap, and color units 20 and 22 disposed on the second portion 16b of the visible light shielding structure 16 may also not overlap, but are not limited thereto. In some embodiments, Figure 11 The light-emitting element 36, the visible light shielding structure 16, the color unit 18, the color unit 20 and the color unit 22 can also adopt the structure of any of the above embodiments. Figure 12Other parts of the electronic device 6 may be similar to or the same as any of the above embodiments, and will not be described in detail here.
[0099] Please refer to Figure 13 and Figure 12 , Figure 13 The diagram shown is a cross-sectional view of the electronic device according to the seventh embodiment of the present invention in an unfolded state and an unfolded state. Figure 12 The image shown is a top view of the electronic device according to the seventh embodiment of the present invention when it is laid flat. Figure 12 As shown, the electronic device 7 provided in this embodiment can be, for example, a slidable display device, which can be expanded from an unexpanded state ST1 to an expanded state ST2, or shrunk from an expanded state ST2 to an unexpanded state ST1, as needed. The electronic device 7 may have a flat area FR and a sliding area SR. When the electronic device 7 is in the unexpanded state ST1, a portion of the sliding area SR can be disposed on the back side of the flat area FR of the electronic device 7. In this case, the width of the electronic device 7 in the sliding direction SD can be reduced, or the display area of the electronic device 7 can be reduced. When the electronic device 7 is in the expanded state ST2, another portion of the sliding area SR can extend to be on the same plane as the flat area FR, and therefore can be used to display a portion of the image, thereby increasing the display area of the electronic device 7.
[0100] exist Figure 12 In some embodiments, the electronic device 7 may include at least one mechanism 44 for switching the state of the electronic device 7 (deployed state ST1 or deployed state ST2). In some embodiments, mechanism 44 may include, for example, a reel motor, a roller, or other suitable mechanism, but is not limited thereto. In other embodiments (not shown), the state of the electronic device 7 may be switched manually by a user or by other means.
[0101] exist Figure 1 In the electronic device 7, a substrate 12, a display layer DL, a recognition pattern layer 14L, and a cover layer 34 are included. The display layer 14 is disposed on the substrate 12, the recognition pattern layer 16 is disposed on the display layer 14, and the cover layer 34 is disposed on the recognition pattern layer 14L. The recognition pattern layer 14L may be, for example, a... Figure 12 The sensing layer TL includes multiple identification patterns 14, but is not limited thereto. The structure of the identification patterns can adopt the identification patterns of any of the above embodiments, and therefore will not be described in detail here. Figure 12 The substrate 12, display layer DL, cover layer 34 and other parts of the electronic device 7 may adopt the electronic device of any of the above embodiments, which will not be described in detail here.
[0102] exist Figure 12In this embodiment, the electronic device 7 may also include a support plate 46 disposed on the surface of the substrate 12 away from the display layer DL, for providing sufficient support for the substrate 12, the display layer DL, and the identification pattern layer 14L. In this embodiment, the portion of the support plate 46 located in the sliding area SR may have multiple openings OP7 to facilitate the bending of the sliding area SR, while the portion located in the flat area FR does not have openings.
[0103] In some embodiments, the electronic device 7 may also include a pad 48 and a chip-on-film (COF) 50, wherein the pad 48 may be located on the substrate 12 on the side of the flat region FR away from the sliding region SR, and the COF 50 may be electrically connected to other components of the electronic device 7 through the pad 48, but is not limited thereto.
[0104] exist Figure 13 In some embodiments, the electronic device 7 may optionally include a digitizer 54 disposed in the flat area FR and located on the side of the support plate 46 away from the substrate 12. The digitizer 54 may be used, for example, to more accurately detect the location of a touch device approaching or touching the electronic device 7; for example, the accuracy of the digitizer 54 in detecting the touch location may be higher than the accuracy in recognizing patterns. The digitizer 54 may, for example, use electromagnetic signals in conjunction with an active or passive stylus or other suitable methods to detect the position of the stylus.
[0105] like Figure 14 As shown, when the electronic device 7 includes a digitizer 54, the distribution density of the identification pattern 14 in the flat area FR may differ from the distribution density of the identification pattern 14 in the sliding area SR. For example, the distribution density of the identification pattern 14 in the flat area FR may be greater than that in the sliding area SR, to meet the different touch accuracy requirements of the flat area FR and the sliding area SR, but this is not limited to this. In some embodiments, when the electronic device 7 includes a digitizer 54 with higher detection accuracy, since the flat area FR can detect the touch position through the digitizer 54, the distribution density of the identification pattern 14 in the flat area FR may also be less than that in the sliding area SR, or the flat area FR of the electronic device 7 may not include the identification pattern 14.
[0106] In some embodiments, the electronic device 7 may not include the digitizer 54. In this case, the distribution density of the identification pattern 14 in the flat area FR may be greater than the distribution density of the identification pattern 14 in the sliding area SR, so that the accuracy of the touch device in determining the touch position in the flat area FR may be higher than that in the sliding area SR, but is not limited thereto.
[0107] Please refer to Figure 14 The diagram shown is a top view of an electronic device according to the eighth embodiment of the present invention. Figure 14As shown, the electronic device 8 provided in this embodiment can be, for example, a foldable device, and the electronic device 8 can have two flat areas FR and a folding area FDR, wherein the folding area FDR is disposed between the flat areas FR. Specifically, the electronic device 8 may also include a support plate 46 disposed on the surface of the substrate 12 away from the display layer DL, for providing sufficient support for the substrate 12, the display layer DL and the sensing layer TL, and the support plate 46 may include a plurality of openings OP8 disposed in the folding area FDR, such that the flat area FR of the electronic device 8 can be folded upward or downward, for example, along the folding axis FL.
[0108] The substrate 12, display layer DL, sensing layer TL, recognition pattern 14, visible light shielding structure 16, color unit 18, color unit 20, color unit 22, protective layer 32, adhesive layer AL, and cover layer 34 of the electronic device 8 can adopt the above embodiments, and therefore can be referred to the above description, without further elaboration here. It should be noted that in Figure 14 In this design, substrate 12, display layer DL, sensing layer TL, identification pattern 14, visible light shielding structure 16, color unit 18, color unit 20, color unit 22, protective layer 32, adhesive layer AL, and cover layer 34 can all be disposed in the flat area FR and the folded area FDR. Since the distribution range of the identification pattern 14 can cover the flat area FR and the folded area FDR, the touch device TD can detect the position of touching the flat area FR and the folded area FDR. In some embodiments, a hardened film layer 52 may also be disposed on the cover layer 34, but it is not limited thereto.
[0109] In some embodiments, such as Figure 12 As shown, the electronic device 8 may optionally include digitizer 541 and digitizer 542, respectively located under the support plate 46 in the corresponding flat area FR. The electronic device 8 may also optionally include heat sink 561 and heat sink 562, respectively located under digitizer 541 and digitizer 542. The electronic device 8 may also optionally include backplate 581 and backplate 582, respectively located under heat sink 561 and heat sink 562. Digitizer 541 and digitizer 542 may be, for example, identical or similar. Figure 14The graphics tablet 54 is not described in detail here. Heat sinks 561 and 562 are used to provide heat dissipation for the graphics tablets 541 and 542 respectively, reducing operational errors caused by overheating. Since the non-flexible graphics tablets 541 and 542, heat sinks 561 and 562, and backplates 581 and 582 are not located in the folding area FDR, this facilitates the folding of the electronic device 8. It should be noted that the number of overlaps between the identification pattern 14 and the graphics tablets 541 and 542 can be greater than the number of non-overlaps. Alternatively, the number of identification patterns 14 in the flat area FR can be greater than the number of identification patterns 14 in the folding area FDR. Since the identification pattern 14 can be set in the folded area FDR, the distribution area of the identification pattern 14 in the top view can be greater than the total distribution area of the digitizing tablet 541 and the digitizing tablet 542.
[0110] In some embodiments, the electronic device 8 may further include a circuit board 621, a connector 641, a circuit layer 622, and a connector 642. The digitizing board 54 disposed in different flat areas FR can be electrically connected to the circuit board 621 and the circuit board 622 respectively. The connector 641 may be disposed on the circuit board 621, and the connector 642 may be disposed on the circuit board 622, so that the digitizing board 54 can be electrically connected to other control elements through the circuit board 621, the circuit board 622, the connector 641, and the connector 642. In some embodiments, the heat sink 561 and the back plate 581 and / or the heat sink 562 and the back plate 582 may also have through holes TH2, so that the digitizing board 54 can be electrically connected to the corresponding circuit board 621 and the circuit board 622 respectively through the corresponding through holes TH2. In some embodiments, the electronic device 8 may not have a folding area FDR and may have a single flat area, making the electronic device 8 non-foldable, but is not limited thereto. In this case, the support plate 46 may not include the opening OP8, and the electronic device may include a single digit tablet, a heat sink, a back plate, a circuit board, and connectors, such that in a top view, the distribution area of the identification pattern 14 may be close to or the same as the distribution area of the digit tablet, but is not limited thereto.
[0111] In some embodiments, the electronic device 8 may further include a circuit board 66, a control element 68, and a connector 70, wherein the control element 68 and the connector 70 are disposed on the circuit board 66, and the control element 68 can be electrically connected to or control elements in the display layer DL, such as the light-emitting elements, transistors, or other elements described above, through the circuit board 66. The connector 70 can further electrically connect the control element 68 or the elements in the display layer DL to external elements.
[0112] In some embodiments, the electronic device 8 may further include a plurality of light-shielding patterns 72, each disposed under a corresponding transistor 38T and located between the substrate 12 and the transistor 38T.Figure 14 In this embodiment, the light-shielding pattern 72 may be disposed between the buffer layer BL and the transistor 38T, but is not limited thereto. The light-shielding pattern 72 can be used to reduce the influence of light incident on the transistor 38T from the substrate 12. The light-shielding pattern 72 may, for example, include a light-shielding material. When the light-shielding pattern 72 includes a metallic material, an insulating layer IN6 may also be disposed between the light-shielding pattern 72 and the transistor 38T, but is not limited thereto.
[0113] In some embodiments, the electronic device 8 may optionally further include a substrate 74 disposed between the support plate 46 and the substrate 12, but is not limited thereto. The substrate 74 may be, for example, a composite substrate. The substrate 74 may include, for example, PI, PET or other suitable materials. Other parts of the electronic device 8 of this embodiment may adopt any of the above embodiments, and therefore will not be described in detail here.
[0114] The following section will further explain the methods by which electronic devices detect touch locations. For example... Figure 15 As shown, when the touch device TD has not yet touched the outer surface 8S of the electronic device 8 or is at a certain height from the outer surface 8S, the touch device TD can detect the identification pattern 14 through invisible light, thereby identifying the position of the touch device TD corresponding to the electronic device 8. When it is determined that the touch device TD is located on the outer surface 8S of one of the flat areas FR of the electronic device 8, the digitizing tablet (e.g., digitizing tablet 561 or digitizing tablet 562) corresponding to the flat area FR can be activated. Therefore, when the touch device TD touches the outer surface 8S, the digitizing tablet can detect the position of the touch device TD. Since the digitizing tablets 561 and 562 are in a closed state before the position of the touch device TD is determined, the power consumption of the digitizing tablets 561 and 562 can be saved, thus achieving the effect of power saving.
[0115] Furthermore, when it is determined that the touch device TD is located on the outer surface 8S of an area without the digitizer 561 and digitizer 562, such as on the outer surface 8S of the folding area FDR of the electronic device 8, the touch sensing mode in the touch device TD can be activated to detect the position of the touch device TD through the touch sensing element, or to obtain the position of the touch device TD through a suitable algorithm. For example, the touch device TD may have capacitive touch functionality and be able to generate capacitance changes to the touch sensing element.
[0116] Please refer to Figure 15 The diagram shown is a top view of an electronic device according to the ninth embodiment of the present invention. Figure 15As shown, the electronic device 9 provided in this embodiment can be a non-self-emissive display device. Taking a liquid crystal display panel as an example, the electronic device 9 in this embodiment may include a circuit board Sub3, a counter substrate Sub4, and a liquid crystal layer LC, wherein the liquid crystal layer LC is disposed between the circuit board Sub3 and the counter substrate Sub4. The opposing substrate Sub4 may include a substrate 76, a visible light shielding structure 16, color units 18, 20, and 22, a protective layer 32, an identification pattern 14, and an insulating layer IN7. The visible light shielding structure 16 may be disposed on the surface of the substrate 76 facing the liquid crystal layer LC. The color units 18, 20, and 22 may be disposed in the openings OP1, OP2, and OP3 of the visible light shielding structure 16, respectively. The protective layer 32 may be disposed on the surfaces of the visible light shielding structure 16, color units 18, 20, and 22 facing the liquid crystal layer LC. The identification pattern 14 may be disposed on the surface of the protective layer 32 facing the liquid crystal layer LC and superimposed on the visible light shielding structure 16. The insulating layer IN7 may be disposed on the surfaces of the identification pattern 14 and the protective layer 32 facing the liquid crystal layer LC. The substrate 76, visible light shielding structure 16, and protective layer 32 of this embodiment may be the same as or similar to the cover layer 34, visible light shielding structure 16, and protective layer 32 of any of the above embodiments, and therefore will not be described in detail here.
[0117] In one embodiment, color unit 18 may not overlap with color unit 20, and the portion of color unit 20 overlapping with the first portion 16b of visible light shielding structure 16 may overlap with the portion of color unit 22 overlapping with the second portion 16b, but is not limited thereto. In some embodiments, Figure 15 Color units 18, 20, and 22 can also adopt the structure of color units 18, 20, and 22 of any of the above embodiments. Figure 15 In some embodiments, the opposing substrate Sub4 may not include a sensing layer, but is not limited thereto.
[0118] In this embodiment, the circuit substrate Sub3 may include a substrate 12, a circuit layer 38, a conductive layer CL3, an insulating layer IN8, and a conductive layer CL4. The conductive layer CL3 is disposed on the circuit layer 38, the insulating layer IN8 is disposed on the conductive layer CL3, and the conductive layer CL4 is disposed on the insulating layer IN8. The substrate 12 and circuit layer 38 in this embodiment may be, for example, the same as or similar to the substrate 12 and circuit layer 38 of any of the above embodiments, and therefore will not be described in detail here. The conductive layer CL3 may include multiple electrodes E3, each electrically connected to the transistor 38T of the circuit layer 38. The conductive layer CL4 may include multiple electrodes E4, and each electrode E4 may have multiple slits, such that the voltage difference between electrodes E3 and E4 can form a horizontal electric field on the liquid crystal layer LC. In other words, Figure 15The liquid crystal display panel may be a fringe-field switching (FFS) liquid crystal display panel, but is not limited thereto. In some embodiments, The liquid crystal display panel can also be other types of liquid crystal display panels, such as horizontally switched or vertically aligned liquid crystal display panels. In some embodiments, the transistor 38T may not overlap with the openings OP1, OP2, and OP3 of the visible light shielding structure 16 to reduce the impact on the display effect. Other parts of the electronic device 9 in this embodiment can adopt any of the above embodiments, and therefore will not be described in detail here.
[0119] In summary, in the electronic device of the present invention, since a location information identification pattern is provided, the electronic device does not require an additional digitizer, thereby reducing the thickness and cost of the electronic device and / or improving its flexibility and application. Furthermore, by providing a visible light blocking structure on the identification pattern to block visible light while allowing invisible light to pass through, the signal-to-noise ratio of the identification pattern can be improved, thereby increasing the accuracy of the detected identification pattern.

Those skilled in the art will recognize that the present invention can have various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
