Description

Technical Field

[0001] The present disclosure relates to a display device, and more particularly to a display device with a high aperture ratio. Background Art

[0002] As display device technology continues to advance, display panels are developing towards small size, thin thickness, or light weight. Therefore, the mainstream display devices on the market have been developing towards thin and light display devices, such as liquid crystal display devices, organic light emitting (OLED) display devices, or micro-organic light emitting (micro-OLED) diode display devices. Among them, thin and light displays can be applied in many fields, including mobile phones, laptops, video cameras, cameras, music players, mobile navigation devices, televisions, etc. used in daily life.

[0003] In a display device, there is usually a single-valued pair margin between a conductive line (e.g., a scan line or a data line) and a light shielding portion (e.g., a black matrix layer). However, on some display devices, if the single-valued pair margin between the conductive line and the light shielding region is maintained, the aperture ratio of the display device will be low.

[0004] In view of this, there is an urgent need to develop a display device that can solve the aforementioned problem of reduced aperture ratio. Summary of the invention

[0005] The present disclosure provides a display device, including a display area, wherein the display area includes a flat area and a bending area. The display device includes a first wire, a second wire, a first shading portion, and a second shading portion. The first wire is arranged in the flat area and extends along a first direction. The second wire is arranged in the bending area and extends along the first direction. The first shading portion overlaps with the first wire and includes a first edge, the first edge extends along the first direction, and the first edge is adjacent to the second wire. The second shading portion overlaps with the second wire and includes a second edge, the second edge extends along the first direction, and the second edge is away from the flat area. The distance between the first wire and the first edge is greater than the distance between the second wire and the second edge. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Implementation Method 1

[0041] Figure 1 It is a top view of the display device of this embodiment. FIG. 2A to FIG. 2D for Figure 1 Magnified images showing different areas of the device before assembly. Figure 3A and Figure 3BSchematic cross-sectional views of the display device of the present embodiment before and after assembly. In one embodiment, the display device may be a flat display device. For example, in some cases, the present disclosure may improve the low aperture ratio caused by shielding light leakage when the photo spacers in the flat display device may scratch the alignment film. In another embodiment, the display device may be a curved display device. The curved display device may have different curvature radii, depending on the design requirements. The present disclosure is not limited thereto.

[0042] The display device of this embodiment includes: a first substrate 11, a second substrate 21, a packaging unit 3, and a display layer 4. The first substrate 11 includes a display area AA and a non-display area B, wherein the display area AA is adjacent to the non-display area B. In some embodiments, the display device is a frameless design, that is, the display device does not have a non-display area B. The second substrate 21 is arranged opposite to the first substrate 11. The packaging unit 3 is arranged on the non-display area B and between the first substrate 11 and the second substrate 21. The display layer 4 is arranged on the display area AA and between the first substrate 11 and the second substrate 21. In one embodiment, the first substrate 11 and the second substrate 21 may be a silicon wafer substrate, a glass substrate, a sapphire substrate, a plastic substrate or other suitable substrates, respectively; in another embodiment, the first substrate 11 and the second substrate 21 may be flexible substrates. For example, the material of the plastic substrate may be, for example, polyimide (PI), polyethylene terephthalate (PET), or polycarbonate (PC), or a combination thereof, but the present disclosure is not limited thereto. The packaging unit 3 may be a packaging glue. In addition, the display layer 4 may include liquid crystal (LC), organic light-emitting diode (OLED), quantum dot (QD), fluorescence material, phosphor material, light-emitting diode (LED), micro light-emitting diode or mini light-emitting diode or other display media. When the display media in the embodiment are different, the structure of the display device may be adjusted as appropriate, but the present disclosure is not limited thereto. In some embodiments, the chip size of the light emitting diode is approximately 300 micrometers (μm) to 10 millimeters (mm), the chip size of the mini LED is approximately 100 micrometers (μm) to 300 micrometers (μm), and the chip size of the micro LED is approximately 1 micrometer (μm) to 100 micrometers (μm), but the present disclosure is not limited thereto.

[0043] like Figure 1As shown, the display area AA may include a central area Rc, a peripheral area Rp and an edge area Re. The central area Rc is disposed at the center of the display area AA, the peripheral area Rp is disposed beside the central area Rc, and the peripheral area Rp does not surround the central area Rc, and the edge area Re is disposed beside the peripheral area Rp, and the edge area Re does not surround the peripheral area Rp or the central area Rc. In one embodiment, the peripheral area Rp may be located on both sides of the central area Rc, and the two peripheral areas Rp are respectively disposed between the central area Rc and the edge area Re. In one embodiment, a center line L of the display area AA may be drawn based on the center point C of the display area AA, and the center line L extends toward the first direction D1. In some embodiments, the center line L is only a reference line, which is located at the center of a specific area in the display area. For example, when the display area includes both a flat display area and a curved display area, the center line L may extend from the center point of the curved display area. The central area Rc, the peripheral area Rp, and the edge area Re are only disposed in the curved display area. However, the present disclosure is not limited thereto, and the specific area may also refer to a planar display area in the display area. In one embodiment, the central area Rc, the peripheral area Rp, and the edge area Re may be sequentially defined by extending from the center line L toward the display edge AA1 and the display edge AA2 of the display area AA. The width of the display edges AA1 and AA2 in the second direction D2 is W, and the second direction D2 may be perpendicular to the first direction D1. In some embodiments, the central area Rc is an area extending from the center line L to the display edges AA1 and AA2 of the display area AA by approximately 15% of the width W (i.e., the width of the central area Rc in the second direction D2 accounts for 30% of the width W); the peripheral area Rp is an area extending from the central area Rc to the display edges AA1 and AA2 of the display area AA by approximately 15% of the width W; and the edge area Re is an area from the peripheral area Rp to the display edges AA1 and AA2, which is approximately 15% of the width W. In another embodiment, the central region Rc is a region extending from the center line L to the display edges AA1 and AA2 of the display area AA by about 10% of the width W; the peripheral region Rp is a region extending from the central region Rc to the display edges AA1 and AA2 of the display area AA by about 35% of the width W; and the edge region Re is a region from the peripheral region Rp to the display edges AA1 and AA2, which is about 5% of the width W. Figure 1 and Figure 3A As shown, in some embodiments, the display device can subsequently bend both sides of the display edges AA1 and AA2 toward the first substrate 11 or the second substrate 21 to form a curved display device. For example, only one side can be bent to form a display device with both a flat surface and a curved surface. A display device with multiple curved surfaces can also be formed. In another embodiment, the display device is a flat display device and may not be bent. Next, the display device will be described by bending both sides of the display edges AA1 and AA2 toward the second substrate 21.

[0044] However, the present disclosure is not limited to this. In other embodiments of the present disclosure, both sides of the display edges AA3 and AA4 of the display area AA may be bent toward the first substrate 11 or the second substrate 21. For example, only one side may be bent to form a display device having both a flat surface and a curved surface. A display device having multiple curved surfaces may also be formed. In another embodiment, the display device is a flat display device and may not be bent. At this time, the definitions of the central area, the peripheral area, and the edge area are similar to those described above, with the difference that the center line is the center line extending along the second direction D2, and the central area, the peripheral area, and the edge area are defined as areas extending from the center line extending along the second direction D2 toward the display edges AA3 and AA4.

[0045] In conventional display devices, there is usually only a single value of pair margin between a conductor (e.g., a scan line or a data line) and a light shielding portion (e.g., a black matrix). However, if there is only a single value of pair margin between a conductor and a light shielding portion on a curved display device, the aperture ratio of the display device will be lower. Therefore, in the display device of this embodiment, the conductor and the light shielding portion are designed to have different pair margins in different areas of the display area to increase the aperture ratio of the display device.

[0046] Next, we will Figure 1 Different regions of the central region Rc, the peripheral region Rp and the edge region Re in the display device are used to illustrate how the disclosure adjusts the pairing margin of the conductive line and the light shielding portion to improve the aperture ratio of the display device.

[0047] FIG. 2A to FIG. 2D They are Figure 1 The enlarged view of the region R1, region R2, region R3, and region R4 of the display device, wherein region R1 is any region of the central region Rc, regions R2 and R3 are any two regions of the peripheral region Rp, and region R4 is any region of the edge region Re. Please also refer to Figure 1 , FIG. 2A to FIG. 2DThe display device of this embodiment includes: a first conductive line 111, a second conductive line 112, a first light shielding portion 221, and a second light shielding portion 222. The first conductive line 111 is disposed in the central region Rc and extends along the first direction D1. The second conductive line 112 is disposed in the peripheral region Rp and extends along the first direction D1. The first light shielding portion 221 overlaps with the first conductive line 111 and includes a first edge 221a, and the first edge 221a extends along the first direction D1. The second light shielding portion 222 overlaps with the second conductive line 112 and includes a second edge 222a, and the second edge 222a extends along the first direction D1. In addition, the display device of this embodiment also includes: a third conductive line 113, and a third light shielding portion 223. The third conductive line 113 is disposed in the edge region Re and extends along the first direction D1. The third light shielding portion 223 overlaps with the third conductive line 113 and includes a third edge 223a, and the third edge 223a extends along the first direction D1. In one embodiment, the third edge 223a of the third light shielding portion is away from the peripheral region Rp. In another embodiment, the third edge 223a is an edge away from the central line L or the center point C.

[0048] In one embodiment, the first wire 111, the second wire 112, and the third wire 113 may respectively include metal, alloy, metal oxide, metal oxynitride, or other electrode materials or circuit materials commonly used in the art. For example, the first wire 111, the second wire 112, and the third wire 113 may be copper, silver, aluminum, molybdenum, tungsten, gold, chromium, nickel, platinum, titanium, copper alloy, aluminum alloy, molybdenum alloy, tungsten alloy, gold alloy, chromium alloy, nickel alloy, platinum alloy, titanium alloy, other suitable metals, combinations of the foregoing, or other conductive materials with good conductivity or low impedance, and the first wire 111, the second wire 112, and the third wire 113 may have a single-layer or multi-layer structure. However, the present disclosure is not limited thereto. In addition, the light shielding layer formed by the first light shielding portion 221, the second light shielding portion 222, and the third light shielding portion 223 may be, for example, a black matrix layer.

[0049] In more detail, in the display device of the present embodiment, the first conductive line 111 includes a first edge 111a and a second edge 111b; the second conductive line 112 includes a third edge 112a and a fourth edge 112b; the third conductive line 113 includes a fifth edge 113a and a sixth edge 113b; the first light shielding portion 221 includes a first edge 221a and a fourth edge 221b, the first edge 221a and the fourth edge 221b extend along the first direction D1, and the first edge 221a is adjacent to the first edge 111a, and the fourth edge 221b is adjacent to the first edge 111a. 21b is adjacent to the second edge 111b; the second shading portion 222 includes a second edge 222a and a fifth edge 222b, the second edge 222a and the fifth edge 222b extend along the first direction D1, and the second edge 222a is adjacent to the third edge 112a, and the fifth edge 222b is adjacent to the fourth edge 112b; the third shading area 223 includes a third edge 223a and a sixth edge 223b, the third edge 223a is adjacent to the fifth edge 113a, and the sixth edge 223b is adjacent to the sixth edge 113b.

[0050] In one embodiment, the light shielding layer including the first light shielding portion 221, the second light shielding portion 222 and the third light shielding portion 223 has a plurality of openings 22a to define the pixel region Px. Figure 3A The first light shielding portion 221 overlaps with the first conductive line 111 in the normal direction (as shown), that is, Figure 1 and Figure 2A Similarly, the definitions of the second light shielding portion 222 overlapping with the second conductive line 112 and the third light shielding portion 223 overlapping with the third conductive line 113 are the same as above, and will not be repeated here.

[0051] like Figure 1 , FIG. 2A to FIG. 2C As shown, in the second direction D2 perpendicular to the first direction D1, the distance between the first conductive line 111 and the first edge 221a (i.e., the first distance X1) and the distance between the second data line 112 and the second edge 222a (i.e., the third distance X3) are different. Here, the so-called first edge 221a and second edge 222a refer to the edges of the first light shielding portion 221 and the second light shielding portion 222 that are farther from the center point C or the center line L of the display area AA. If Figure 2A In the case shown, since the distances between the edges of the first light shielding portion 221 on both sides of the first conductive line 111 and the center point C or the center line L of the display area AA are substantially the same, any edge of the first light shielding portion 221 can be used as the first edge 221a, and is not limited to Figure 2AIn one embodiment, the first edge 221a is adjacent to the peripheral region Rp, and the second edge 222a is away from the central region Rc. In another embodiment, the first edge 221a is adjacent to the second conductive line 112.

[0052] In other words, if Figure 1 , FIG. 2A to FIG. 2C As shown, in the second direction D2 perpendicular to the first direction D1, there is a first distance X1 between the first edge 111a and the first edge 221a, a second distance X2 between the second edge 111b and the fourth edge 221b, a third distance X3 between the third edge 112a and the second edge 222a, and a fourth distance X4 between the fourth edge 112b and the fifth edge 222b, and the difference between the first distance X1 and the second distance X2 is not equal to the difference between the third distance X3 and the fourth distance X4.

[0053] When the display device of this embodiment has the above-mentioned design, the center line of the conductive wire and the light shielding portion can be misaligned differently in different areas of the display area. At the same time, the distance between the above-mentioned light shielding portions can be adjusted according to the different curvatures of the display panel to be bent, so that the difference between the edge of the light shielding portion and the edge of the conductive wire is different in different areas. In this way, after the display panel is bent, the display device can still maintain a high aperture ratio and / or color point unchanged.

[0054] like Figure 1 and FIG. 2A to FIG. 2D As shown, in the second direction D2 perpendicular to the first direction D1, the distance between the first conductive line 111 and the first edge 221a (i.e., the first distance X1) is greater than the distance between the second conductive line 112 and the second edge 222a (i.e., the third distance X3), and the difference between the first distance X1 and the second distance X2 is less than the difference between the third distance X3 and the fourth distance X4. In addition, in this embodiment, the distance between the third conductive line 113 and the third edge 223a (i.e., the fifth distance X5) is less than the distance between the first conductive line 111 and the first edge 221a (i.e., the first distance X1) (herein, the so-called third edge 223a refers to the edge of the third light shielding region 223 that is farther from the center point C or the center line L of the display area AA); in other words, there is a fifth distance X5 between the fifth edge 113a and the third edge 223a, and there is a sixth distance X6 between the sixth edge 113b and the sixth edge 223b, and the difference between the first distance X1 and the second distance X2 is less than the difference between the fifth distance X5 and the sixth distance X6.

[0055] In this embodiment, the distance between the third conductive line 113 and the third edge 223a (i.e., the fifth distance X5) is greater than the distance between the second data line 112 and the second edge 222a (i.e., the third distance X3), and the difference between the third distance X3 and the fourth distance X4 is greater than the difference between the fifth distance X5 and the sixth distance X6. Figure 3AAs shown, the third conductive line 113 and the third edge 223a are located in the edge region Re, and the edge region Re is adjacent to the non-display region B. In one embodiment, the packaging unit 3 on the non-display region B prevents the relative position of the third conductive line 113 and the third light shielding portion 223 from shifting too much after the display panel is bent. Therefore, the closer the third light shielding portion 223 in the edge region Re to the non-display region B is, the smaller the difference between the fifth distance X5 and the sixth distance X6 will be.

[0056] In another embodiment, the central region Rc includes two adjacent first conductive lines 111, the spacing between the two adjacent first conductive lines 111 (which may be defined as the distance between the center of one of the first conductive lines 111 and the center of the other first conductive line 111, or the distance between the edge of one of the first conductive lines 111 and the corresponding edge of the other first conductive line 111) is a first spacing Y1, the adjacent first conductive lines 111 have corresponding adjacent first light shielding portions 221, the spacing between the adjacent first light shielding portions 221 (which may be defined as the distance between the center of one of the first light shielding portions 221 and the center of the other first light shielding portion 221, or the distance between the edge of one of the first light shielding portions 221 and the corresponding edge of the other first light shielding portion 221) is a second spacing Y2. The spacing between the two adjacent second conductive lines 112 in the peripheral region Rp is a third spacing Y3, the adjacent second conductive lines 112 have corresponding adjacent second light shielding portions 222, and the distance between the adjacent second light shielding portions 222 is a fourth spacing Y4. The difference between the first spacing Y1 and the second spacing Y2 is defined as a first difference, and the difference between the third spacing Y3 and the fourth spacing Y4 is defined as a second difference, wherein the first difference is different from the second difference. In some embodiments, the first difference is smaller than the second difference.

[0057] In another embodiment, the central region Rc includes two adjacent first conductive lines 111, the distance between the two adjacent first conductive lines 111 is a first interval, the adjacent first conductive lines 111 have corresponding adjacent first light shielding portions 221, and the distance between the adjacent first light shielding portions 221 is a second interval. The distance between two adjacent second conductive lines 112 in the peripheral region Rp is a third interval, the adjacent second conductive lines 112 have corresponding adjacent second light shielding portions 222, and the distance between the adjacent second light shielding portions 222 is a fourth interval. The difference between the first interval and the second interval is defined as a first difference, and the difference between the third interval and the fourth interval is defined as a second difference, wherein the first difference is different from the second difference.

[0058] Figure 3A and Figure 3B1 and 12 are cross-sectional schematic diagrams of a display device according to an embodiment of the present embodiment before bending and after bending. When the display device of the present embodiment has the above-mentioned design, although the first conductive wire 111, the second conductive wire 112 and the third conductive wire 113 in the central region Rc, the peripheral region Rp and the edge region Re before bending and the first light shielding portion 221, the second light shielding portion 222 and the third light shielding portion 223 have different offset designs according to the curvature of the desired bending (such as Figure 3A However, after bending, the first conductive line 111 and the first light shielding portion 221 in the central region Rc, the second conductive line 112 and the second light shielding portion 222 in the peripheral region Rp, and the third conductive line 113 and the third light shielding portion 223 in the edge region Re are no longer misaligned (as shown in FIG. Figure 3B shown).

[0059] In addition, if FIG. 2A to FIG. 2D As shown, in the display device of this embodiment, the sum of the first spacing X1 and the second spacing X2 is equal to the sum of the third spacing X3 and the fourth spacing X4, and is also equal to the sum of the fifth spacing X5 and the sixth spacing X6. Therefore, the display device of this embodiment not only has the advantage of a high aperture ratio, but also has the advantage of maintaining a constant color point.

[0060] In some embodiments, the display device is bent toward the first substrate 11, and the distance between the conductive line and the edge of the light shielding portion can be the same as the above FIG. 2A to FIG. 2D For example, when the display device is bent toward the first substrate 11, the third distance X3 in the region R2 is greater than the fourth distance X4. The distances between the conductive line and the edge of the light shielding portion in the regions R2, R3, and R4 can be deduced similarly.

[0061] For example, in a 27-hour curved display device with a single pair of group margin design in the past, assuming that after the curved display device completes the bending process, the maximum offset between the wire and the light shielding portion is 14μm; at this time, regardless of which area of ​​the display surface, the first spacing X1 to the sixth spacing X6 are all 14μm, and the final aperture ratio is about 36.75%. However, according to the aforementioned embodiment of the present disclosure, the first distance X1 and the second distance X2 can be designed to be 7μm, the maximum value of the fourth distance X4 is less than 14μm, and the minimum value of the third distance X3 exceeds 0μm; at this time, the aperture ratio obtained can be increased to about 57.40%.

[0062] In this embodiment, Figures 1 to 3BThe first conductive wire 111, the second conductive wire 112, and the third conductive wire 113 are described as data lines. However, the present disclosure is not limited thereto. In other embodiments of the present disclosure, the first conductive wire 111, the second conductive wire 112, and the third conductive wire 113 may also be scan lines. When the first conductive wire 111, the second conductive wire 112, and the third conductive wire 113 are scan lines, the misalignment design between the first conductive wire 111, the second conductive wire 112, and the third conductive wire 113 and the light shielding portion is similar to the above, so it will not be described in detail here.

[0063] like Figure 3A and Figure 3B As shown, the display device of this embodiment is bent toward the second substrate 21. In the display device obtained by bending the display panel, the central area Rc is a relatively flat area with the smallest curvature (i.e., the largest curvature radius); while the peripheral area Rp is a relatively curved area with the largest curvature (i.e., the smallest curvature radius), and the curvature (or curvature radius) of the edge area Re is roughly between the central area Rc and the peripheral area Rp. Here, the central area Rc can be regarded as the first area with a large curvature radius, and the peripheral area Rp or the edge area Re can be regarded as the second area with a small curvature radius; or, the peripheral area Rp can be regarded as the first area with a large curvature radius, and the edge area Re can be regarded as the second area with a small curvature radius. In addition, in one embodiment, the display device can have a flat area and a bending area. The wires in the flat area and their corresponding light shielding parts can be designed without misalignment. In another embodiment, the display device has multiple bending areas, and these bending areas can have different curvature radii and different bending directions (for example, bending toward the first substrate 11 or the second substrate 21).

[0064] In some embodiments, the display area of ​​the display device includes a first area and a second area. The radius of curvature of the first area is greater than the radius of curvature of the second area. The first area includes two adjacent conductive wires, and the spacing between the two adjacent conductive wires (which can be defined as the distance between the center of one conductive wire to the center of another conductive wire, or defined as the distance between the edge of one conductive wire to the corresponding edge of another conductive wire) is the first spacing, and the two adjacent conductive wires have corresponding adjacent shading parts, and the spacing between the two adjacent shading parts is the second spacing. The second area includes two adjacent conductive wires, and the spacing between the two adjacent conductive wires is the third spacing, and the two adjacent conductive wires have corresponding adjacent shading parts, and the spacing between the two adjacent shading parts is the fourth spacing. The difference between the first spacing and the second spacing is defined as the first difference, and the difference between the third spacing and the fourth spacing is defined as the second difference, wherein the first difference is different from the second difference. In some embodiments, the first difference is less than the second difference.

[0065] In another embodiment, the display area of ​​the display device includes a first area and a second area. The radius of curvature of the first area is greater than the radius of curvature of the second area. The first area includes two adjacent wires, the distance between the two adjacent wires is a first interval, the two adjacent wires have corresponding adjacent shading portions, and the distance between the two adjacent shading portions is a second interval. The second area includes two adjacent wires, the distance between the two adjacent wires is a third interval, the two adjacent wires have corresponding adjacent shading portions, and the distance between the two adjacent shading portions is a fourth interval. The difference between the first interval and the second interval is defined as a first difference, and the difference between the third interval and the fourth interval is defined as a second difference, wherein the first difference is different from the second difference. In some embodiments, the first difference is smaller than the second difference.

[0066] It should be noted that the above-mentioned radius of curvature may be the radius of curvature measured in the first area or the second area of ​​the same surface of the first substrate 11. Alternatively, the radius of curvature may also be the radius of curvature measured in the first area or the second area of ​​the same surface of the second substrate 21.

[0067] Implementation Method 2

[0068] Figure 4 1 is a top view of a display device according to an embodiment of the present embodiment. The design of the display device of the present embodiment is similar to that of the embodiment 1; the difference is that the staggered design of the conductive line and the light shielding portion of the present embodiment is a staggered arrangement of the scanning line and the light shielding portion. The definitions of the central region Rc, the peripheral region Rp and the edge region Re of the display device of the present embodiment are similar to those of the embodiment 1 and will not be repeated.

[0069] Figure 5A , Figure 5B and Figure 5C for Figure 4 Shows enlarged views of different areas of the device. Figure 5A The design can refer to Figure 2A , Figure 5B and Figure 5C The design can refer to Figure 2B and Figure 2C , so I will not go into details here. In addition, if FIG. 5A to FIG. 5C As shown, the display device of this embodiment further includes a spacer element 5, which is disposed between the first wire 111 and the first light shielding portion 221 and between the second wire 112 and the second light shielding portion 222. When the user does not grasp the display device, the center of the spacer element 5 corresponds to the center of the first data line 111 and the second data line 112.

[0070] Figure 5B' is an enlarged view of a portion of the display device after the user grabs the display device. However, when the user grabs the display device, the force applied by the user may cause the spacer element 5 to shift toward one side of the first substrate, which may damage the alignment film in the display layer and cause light leakage. However, in this embodiment, when the user grabs the area R2, the original Figure 5B The position of the spacer element 5 will be changed as a result of the grabbing. Figure 5B When the user grasps the display device upward along the second direction D2, even if the spacer 5 deviates downward along the second direction D2 toward one side of the first substrate and damages the display layer, since the display device of this embodiment is designed such that the third distance X3 is smaller than the fourth distance X4, the second light shielding portion 222 can shield the corresponding position of the damaged alignment film to avoid light leakage.

[0071] In the above-mentioned embodiments of the present disclosure, the numbers of the conductive lines and the light shielding portions are only used for illustration, and the numbers of the conductive lines and the light shielding portions included in the display device of the present disclosure are not limited thereto.

[0072] The display device disclosed herein can be used in combination with a touch panel as a touch display device. At the same time, the display device or touch display device disclosed herein can be applied to any electronic device known in the art that requires a display screen, such as a monitor, a mobile phone, a notebook computer, a video camera, a camera, a music player, a mobile navigation device, a television, or other electronic device that requires displaying an image.
