Description

[0001] This invention is a divisional application of the invention patent application with application number 202011252921.9 filed on November 11, 2020, and the invention name is "Transparent Display Device". Technical Field

[0002] The present disclosure relates to a display device, and in particular to a transparent display device. Background Art

[0003] During operation, a transparent display device typically displays an image to a user. However, if the transparent display device includes a transparent portion, the user can still see the surrounding background of the transparent display device. The transparent display device includes a transparent portion to allow ambient light to pass through the transparent display device, allowing the user to simultaneously view the image and the background scene. In this case, at least a portion of the background scene behind the transparent display device is not obstructed by the transparent display device.

[0004] To control the pixels, transparent display devices still require data and gate lines to control the pixel display image. Background light will pass through the transparent portion, or through the transparent portion of the pixel. As pixel size decreases, background light energy will be diffracted by the data and gate lines, or even the black matrix. As a result, the background scene or background pattern visible through the transparent portion may become blurred due to diffraction.

[0005] As the development of transparent display devices continues, reducing the blur effect of transparent display devices is at least one of the factors that need to be improved. Summary of the Invention

[0006] The present disclosure provides a transparent display device in which a transparent portion is implemented to reduce diffraction effects.

[0007] In an embodiment, the present disclosure provides a transparent display device including a pixel region, a first transparent region, and a second transparent region. The first transparent region is adjacent to the pixel region, and the second transparent region is adjacent to the first transparent region. The area of ​​the first transparent region is different from the area of ​​the second transparent region.

[0008] In an embodiment, the present disclosure provides a transparent display device, including a gate line, a first electrode, a second electrode, a first transparent area, a second transparent area, and at least one metal line. The gate line has an extension direction, the second electrode is adjacent to the first electrode, the first transparent area is adjacent to the first electrode, and the second transparent area is adjacent to the second electrode, wherein the first electrode and the second electrode are arranged between the first transparent area and the second transparent area along the extension direction, and at least one metal line is arranged between the first electrode and the second electrode.

[0025] The present disclosure relates to a transparent display device, in which the setting of the transparent area of ​​the present disclosure can at least reduce the visual effect caused by the diffraction phenomenon from the opaque parts of the pixel array, such as data lines or gate lines or even the black matrix.

[0026] Several embodiments are provided for the present disclosure, but the present disclosure is not limited to the embodiments. In addition, the present disclosure also allows for appropriate combinations between the provided embodiments. In addition, the expressions "an element overlies another element," "an element is disposed above another element," "an element is disposed on another element," and "an element is disposed on another element" may indicate that the element is in direct contact with the other element, or that the element is not in direct contact with the other element, that is, one or more intermediate elements are disposed between the element and the other element.

[0027] It should be understood that although the terms "first," "second," "third," etc. may be used herein to describe various elements, components, regions, layers, parts, and / or sections, these elements, components, regions, layers, parts, and / or sections should not be limited by these terms. These terms are merely used to distinguish one element, component, region, layer, part, or section from another element, component, region, layer, or section. Thus, a first element, component, region, layer, part, or section discussed below may be referred to as a second element, component, region, layer, part, or section without departing from the teachings of the present disclosure.

[0028] Figure 1 This is a diagram schematically showing the basic pixel structure of a transparent display device. Figure 1, the basic pixel structure of the transparent display device in the example may include a pixel area 100 and a transparent area 104. The pixel area 100 may include sub-pixels, and the sub-pixels include a data line 50 and a gate line 52, a transistor 56, a color filter 57 and a pixel electrode 102. In some embodiments, the pixel area may include at least three sub-pixels. In addition, the transparent display device also includes a black matrix 54 that can be arranged on the data line 50, the gate line 52 or the transistor 56. For example, the data line 50 and the gate line 52 can define an area including the pixel area 100 and the transparent area 104. In some embodiments, a transparent area is defined by the data line 50, the gate line and the black matrix 54, and the transparent area does not include the pixel area 100. Generally speaking, the transparent display device may also include a backlight source. The backlight source may be a light-emitting diode (LED). In some embodiments, the light-emitting diode may include an organic light-emitting diode (OLED), a quantum dot light-emitting diode (QLED), a sub-millimeter light-emitting diode (mini LED), or a micro light-emitting diode (micro LED), but is not limited thereto. The transparent display device may include multiple basic pixel structures 1, wherein the color filter 57 in the basic pixel structure 1 may be red, green, or blue. In other embodiments, the color filters 57 may be the same color. However, the present disclosure is not limited to the embodiments described.

[0029] The transparent area 104 in the transparent display device allows light from the background to pass through. Therefore, the user can see the displayed image and a portion of the background behind the transparent display device.

[0030] The structure of the transparent area 104 will determine the quality of the background scene that is seen. Therefore, the problem of transparent area 104 should be studied. Then, the blurring effect of the background scene can be reduced by adjusting the configuration of the transparent area.

[0031] When considering the performance of transparent display devices, it is also necessary to consider the diffraction effect when viewing the background. In traditional structures, the diffraction effect is significant, causing a non-negligible blurring effect.

[0032] Figure 2 FIG is a diagram schematically showing a transparent area in a pixel array of a transparent display device according to an embodiment of the present disclosure. Figure 2Regarding region 150 , pixel region 152 is arranged along direction D1 along with two transparent regions 154 and 156 as shown by the dotted line. Pixel region 152 may include three sub-pixels 152 a , 152 b , and 152 c disposed between transparent region 154 and another transparent region 156 . Figure 2 The figure in FIG is a top view of a color filter substrate. Within the color filter substrate, the structural portion 60 may include thin film transistors (TFTs) and other actual components disposed on the TFT substrate, but these are not shown in this schematic diagram. It should also be noted that the thin film transistors and color filter 62 may be disposed on the same or different sides of the substrate. As indicated by the dashed lines, in this embodiment, a region 150 including a pixel region 152 and two transparent regions 154 and 156 is used as an example. In one embodiment, the spacing A between the transparent region 154 and the transparent region 156 may be the minimum distance from the center point of the transparent region 154 to the center point of the transparent region 156 along direction D1. In one embodiment, the sub-pixels 152a, 152b, and 152c may have a first width w1 along direction D1. The transparent regions 154 and 156 may have a second width w2 along direction D1. Figure 5 The first width w1 and the second width w2 will be further described. Alternatively, in another embodiment, the spacing A between the transparent area 154 and the transparent area 156 may be the distance from a reference point at an edge (e.g., an upper edge) of the transparent area 154 to the same reference point at an edge (e.g., an upper edge) of the transparent area 156 along the direction D1. In the present disclosure, the spacing A between the transparent area 154 and the transparent area 156 is increased. The black matrix 54 may cover the data lines, gate lines, and thin film transistors. However, in other embodiments, the black matrix 54 may partially cover device elements such as gate lines, data lines, drive transistors, pixel electrodes, etc., but the present disclosure is not limited thereto.

[0033] The black matrix 54 can be selectively arranged or not arranged as required. The present disclosure can increase the spacing A between two adjacent transparent areas 154 and 156 to reduce interference and improve display quality. In addition, the present disclosure is not limited to the above-mentioned embodiment of the black matrix 54.

[0034] The drawings of the aforementioned features are merely examples. However, other embodiments and / or other drawings having the aforementioned features may also fall within the scope of protection of the aforementioned disclosure.

[0035] Figure 3 According to the embodiment of the present disclosure, Figure 2 The pixel array in the figure corresponds to the pixel structure. Figure 3, only a portion of the black matrix 54 is shown covering device elements, such as gate lines 52. In one embodiment, two adjacent gate lines 52 are covered by a thicker black matrix 54. Similarly, the data line 50 may also be covered by another portion of the black matrix 54. In addition, the area 53 between the two color filters 62 or the area 53 between the transparent area 154 and the color filter 62 may also be selectively provided with a black matrix 54. In other words, a black matrix 54 may be selectively formed at the position according to design requirements. In one embodiment, two adjacent data lines 50, gate lines 52 and the black matrix may be defined as a pixel area 152. In addition, in one embodiment, the transparent area 154 may be composed of two adjacent data lines 50, an area 53 (an area where a black matrix may or may not be provided), and a gate line ( Figure 3 (not shown) . On the other hand, the black matrix described in this embodiment is used to illustrate the location corresponding to the TFT-side substrate. Black matrix 54 can be provided on a color filter substrate or a TFT substrate, but is not limited thereto. The above description of black matrix 54 is also applicable to other embodiments with similar schematic diagrams and will not be repeated here.

[0036] A theoretical basis is provided in order to see how the diffraction effect can be reduced by increasing the spacing of the transparent areas. Figure 4 FIG is a diagram schematically illustrating the diffraction effect according to an embodiment of the present disclosure. Figure 4 , showing the diffraction mechanism corresponding to the smaller spacing "a" and the larger spacing "A" between the two transparent areas. The diffraction effect 190 under the spacing "a" should satisfy the diffraction condition in optical theory:

[0037] a·sinθ=λ,

[0038] Where θ is the diffraction angle and λ is the wavelength. Figure 4 In the right part, the diffraction effect 192 under the larger spacing "A" in optical theory should meet the diffraction conditions in optical theory.

[0039] A·sinθ'=λ.

[0040] At a given wavelength λ, if the pitch "A" is larger than the pitch a, the diffraction angle θ' at the pitch "A" decreases. This means that the diffraction angle θ' of the first-order diffraction pattern, which causes the blurring effect, is closer to 0 degrees. The diffraction angle θ' can also be defined as the angle between the normal direction N and the direction of light travel. This reduces the blurring effect caused by diffraction.

[0041] The present disclosure may increase the spacing between two adjacent transparent regions 154 , 156 , such as a larger spacing “A”.

[0042] Figure 5FIG is a diagram schematically showing a transparent area in a pixel array of a transparent display device according to an embodiment of the present disclosure. Figure 5 In this embodiment, four sub-pixels 152a, 152b, 152c, and 152d are arranged along the direction D1. In one embodiment, the four sub-pixels 152a, 152b, 152c, and 152d arranged along the direction D1 may form the pixel region 152.

[0043] In some embodiments, the sizes and widths of the transparent regions 154 and 156 along direction D1 may be the same or different, and the shapes of the transparent regions 154 and 156 may be the same or different. In this embodiment, when the four sub-pixels 152a, 152b, 152c, and 152d are arranged together, the spacing A between the transparent regions 154 and 156 increases. However, in the present disclosure, the black matrix may be selectively arranged according to actual design requirements. The present disclosure is not limited to the above embodiment.

[0044] In this embodiment, one of the transparent regions 154 and 156 has a first width w1 that is the largest along direction D1, and one of the at least three sub-pixels 152a, 152b, etc. has a second width w2 that is the largest along direction D1. The first width w1 is different from the second width w2. In some embodiments, the second width w2 may refer to the width of one sub-pixel 152a or 152b. However, in other embodiments, the second width w2 may refer to the width obtained by dividing the distance between two adjacent sides of two adjacent transparent regions 154 and 156 along direction D1 by the number of sub-pixels 152a, 152b, etc. arranged within this distance.

[0045] In one embodiment, the ratio of the first width w1 to the second width w2 may be greater than or equal to 0.01 and less than 1. In another embodiment, the ratio of the first width w1 to the second width w2 may be greater than 1 and less than or equal to 200, but the present disclosure is not limited to this ratio.

[0046] In some embodiments, along the direction D1 , the transparent region 154 and the transparent region 156 are of the same size, or the transparent region 156 is longer than the transparent region 154 , but the present disclosure is not limited thereto.

[0047] In some embodiments, the pixel region 152 includes at least three sub-pixels, for example Figure 2 The three sub-pixels 152a, 152b, 152c or Figure 5In some embodiments, the pixel region 152 further includes another transparent region (not shown) disposed between any two sub-pixels in the at least three sub-pixels along the direction (D1).

[0048] In some embodiments, the transparent regions 154 and 156 are permanently transparent regions or are transparent regions that are switched. The permanently transparent regions may, for example, comprise a transparent material. However, some materials, for example, may have an opaque state but can be switched to a transparent state by applying a bias voltage. In other words, the present disclosure may select different transparent materials based on actual needs. In some embodiments, the transparent regions may or may not include pixel electrodes. If pixel electrodes are included in the transparent regions, an operating voltage may be applied to the pixel electrodes to cause them to be in a bright state, i.e., in a transparent state.

[0049] In some embodiments, the transparent display device may further include another transparent region disposed between any two sub-pixels of the at least two sub-pixels. Figure 6 FIG. 1 schematically illustrates a transparent area and another transparent area in a pixel array of a transparent display device according to an embodiment of the present disclosure.

[0050] The drawings of the aforementioned features are merely examples. However, other embodiments and / or other drawings having the aforementioned features may also fall within the scope of protection of the aforementioned disclosure.

[0051] Reference Figure 6 In one embodiment, the transparent display device may include a unit area 200. The unit area 200 includes a first transparent area 202 and at least two sub-pixels 152a and 152b arranged adjacent to the first transparent area 202 along a direction D1. The unit area 200 may further include a second transparent area 204 disposed between the at least two sub-pixels 152a and 152b as needed. Figure 6In the illustrated embodiment, the unit area 200 sequentially includes a sub-pixel 152a, a second transparent area 204, a sub-pixel 152b, and a first transparent area 202 along the direction D1. The first transparent area 202 has a maximum third width w3 along the direction D1. The second transparent area 204 has a minimum fourth width w4 along the direction D1. The fourth width w4 of the second transparent area 204 is less than the third width w3 of the first transparent area 202. In some embodiments, the ratio R of the fourth width w4 of the second transparent area 204 to the third width w3 of the first transparent area 202 may be, for example, in the range of 0 < R ≤ 0.5. For example, the unit area may refer to the smallest unit that is repeated in the pixel array. In one embodiment, at least two sub-pixels 152a, 152b have a maximum width w' along the direction D1. The ratio of the third width w3 to the width w' may be, for example, greater than or equal to 0.01 and less than 1. In another embodiment, the ratio of the third width w3 to the width w' may be, for example, greater than 1 and less than or equal to 200, but the present disclosure is not limited to this ratio. For example, the width w' may refer to the distance between two adjacent edges of the first transparent area 202 and the second transparent area 204 along the direction D1, but the present disclosure is not limited to this. <00​​​​​​​​​​​​​Schematic diagram of the arrangement of the first transparent region 202 and the second transparent region 204 , in which the blurring effect in the diffraction effect 198 can be reduced.

Each of the at least two first areas 160 includes at least three transparent areas, for example, three transparent areas in an embodiment. Each of the at least two pixel areas 162 includes at least three sub-pixels, for example, three sub-pixels in an embodiment. The at least two first areas 160 and the at least two pixel areas 162 are arranged alternately along direction D1 and direction D2. Direction D1 is different from direction D2. In one embodiment, the first areas 160 and the pixel areas 162 are arranged alternately and adjacently along direction D1 and second direction D2. The first areas 160 are arranged non-adjacently along direction D1 and second direction D2. In one embodiment, the pixel area 162 is arranged between two adjacent first areas 160 along direction D1 and second direction D2. Similarly, the first area 160 is arranged between two adjacent pixel areas 162 along direction D1 and second direction D2.

[0058] In some embodiments, along direction D1, the width of the first region 160 is equal to the width of the pixel region 162. Along direction D2, the width of region 160 is equal to the width of pixel region 162. In some embodiments, pixel region 162 forms a full pixel (e.g., including red, green, and blue sub-pixels). Depending on the actual design, pixel region 162 may include sub-pixels of other compensating colors. In another embodiment, at least two pixel regions 162 include six sub-pixels, but are not limited thereto. In some embodiments, the transparent display device further includes another transparent region ( Figure 8 This arrangement can be referred to Figure 9 ,and Figure 9 This will be further described below. In addition, between two adjacent transparent areas arranged along the direction D1, as shown in FIG. Figure 2 The spacing A described in the embodiment shown can be increased. By increasing the spacing A of the transparent areas, the diffraction effect is reduced.

[0065] Figure 11A and Figure 11B FIG is a diagram schematically showing a transparent area and another transparent area in a pixel array of a transparent display device according to an embodiment of the present disclosure. Figure 11A The width of the first transparent area in direction D2 can be increased by including two sub-pixels along direction D2. Generally speaking, in an embodiment, the transparent display device includes a unit area 170, which includes a first transparent area 172, a second transparent area 176, a sub-pixel 174a, and a sub-pixel 174b. Sub-pixels 174a and 174b are arranged along direction D2. In another embodiment, unit area 170 may further include at least two sub-pixels 174a and 174b. Direction D1 and direction D2 intersect. The first transparent area 172 is adjacent to sub-pixel 174a and sub-pixel 174b along direction D1. The second transparent area 176 extends between the two sub-pixels 174a and 174b along direction D1. The first transparent area 172 has a fifth width w5 that is the largest along direction D2, and the second transparent area 176 has a sixth width w6 that is the smallest along direction D2, and the fifth width w5 is greater than the sixth width w6. In one embodiment, direction D2 may be substantially parallel to the extension direction of the gate line. In another embodiment, direction D2 intersects with the extension direction of the data lines. In the present disclosure, direction D2 and the extension direction of the data lines are different. For example, direction D2 may be perpendicular to the extension direction of the data lines, or direction D2 may include an angle (e.g., 75 to 90 degrees or 80 to 90 degrees) with the extension direction of the data lines, but the present invention is not limited thereto.

[0066] In this embodiment, along the direction D2, the distance between two adjacent first transparent areas 172 is as follows: Figure 2 The spacing A is shown to be increased. By increasing the spacing A between adjacent transparent areas, diffraction effects can be reduced.

Then, the sixth width w6 decreases. In some embodiments, the color filters of the two sub-pixels 174a and 174b may contact each other, wherein the sixth width w6 may be close to or equal to zero. In this embodiment, along the direction D2, the distance between the two adjacent first transparent areas 172 is as shown in FIG. Figure 2 The spacing A shown is increased.
