Description

Technical Field

[0001] The present invention relates to a display, and more particularly to a transparent display. Background Art

[0002] Existing transparent displays have a circuit pattern layer, which is usually distributed in the display area of the transparent display and has a plurality of light-emitting blocks. Each of these blocks has a low light transmittance, thus blocking light. Each block has a small size to reduce the impact on the overall light transmittance of the transparent display. However, these blocks usually cause light diffraction, resulting in a decrease in the image quality of the transparent display affected by light diffraction. Summary of the Invention

[0003] At least one embodiment of the present invention provides a transparent display that can reduce the high-frequency noise intensity, thereby improving the image quality.

[0004] The transparent display provided by at least one embodiment of the present invention includes a plurality of light-transmitting blocks, a plurality of horizontal lines, a plurality of vertical lines, and a plurality of driving electrode blocks. These horizontal lines extend along a plurality of parallel horizontal reference lines, and a part of the horizontal lines is distributed on one of the horizontal reference lines. These vertical lines extend along a plurality of parallel vertical reference lines, and a part of the vertical lines is distributed on one of the vertical reference lines. The extending direction of each horizontal reference line is different from the extending direction of each vertical reference line. These driving electrode blocks connect these horizontal lines and these vertical lines, and these horizontal lines, these vertical lines, and these driving electrode blocks are distributed in a mesh pattern along these horizontal reference lines and these vertical reference lines, and these horizontal lines, these vertical lines, and these driving electrode blocks surround these light-transmitting blocks. Each driving electrode block has at least one first edge and at least one second edge. The first edge extends along a first straight line. The second edge extends along a second straight line. A first acute angle is formed between the intersecting first straight line and the horizontal reference line, and a second acute angle is formed between the intersecting second straight line and the horizontal reference line.

[0005] In at least one embodiment of the present invention, each of the first acute angle and the second acute angle is between 35 degrees and 55 degrees.

[0006] In at least one embodiment of the present invention, the edges of each light-transmitting block surround a geometric pattern, and any interior angle of the geometric pattern is greater than or equal to 125 degrees.

[0007] In at least one embodiment of the present invention, each driving electrode block includes a plurality of electrode pads. At least one electrode pad extends along the direction of the first straight line or the second straight line.

[0008] In at least one embodiment of the present invention, at least two electrode pads extend along the direction of a first straight line and the direction of a second straight line respectively.

[0009] In at least one embodiment of the present invention, each driving electrode block further includes a plurality of light-emitting elements. These light-emitting elements are disposed on these electrode pads and electrically connected to these electrode pads.

[0010] In at least one embodiment of the present invention, a curved edge is formed between an edge of one of these horizontal trace lines and these vertical trace lines and an edge of the driving electrode block connected thereto.

[0011] In at least one embodiment of the present invention, the shape of at least one of these horizontal trace lines is a curve or a broken line.

[0012] In at least one embodiment of the present invention, the shape of at least one of these vertical trace lines is a curve or a broken line.

[0013] In at least one embodiment of the present invention, the edge of at least one light-transmissive block surrounds an X shape, and the X shape extends along a direction parallel to the first straight line and a direction parallel to the second straight line.

[0014] Since the first edge and the second edge of each driving electrode block extend along the first straight line and the second straight line respectively, and both the first straight line and the second straight line intersect with a horizontal reference line to form a first acute angle and a second acute angle, the directions of the first edge and the second edge are neither parallel nor perpendicular to the direction of any of the horizontal trace lines and the vertical trace lines. Thus, all edges of each light-transmissive block will extend along more than three directions to disperse high-frequency noise, thereby reducing the high-frequency noise intensity to improve the image quality.

[0061] In the following text, for the purpose of clearly presenting the technical features of the present case, the dimensions (such as length, width, thickness, and depth) of the elements (such as layers, films, substrates, and regions, etc.) in the drawings are enlarged in a non-uniform scale, and the number of some elements is reduced. Therefore, the descriptions and explanations of the following embodiments are not limited to the number of elements in the drawings and the dimensions and shapes presented by the elements, but should cover the dimensions, shapes, and deviations of both caused by actual processes and / or tolerances. For example, the flat surfaces shown in the drawings may have rough and / or non-linear features, and the acute angles shown in the drawings may be rounded. Therefore, the elements presented in the drawings of the present case are mainly for illustration purposes, not intended to accurately depict the actual shapes of the elements, nor to limit the scope of the patent application of the present case.

[0062] Secondly, words such as "about", "approximate", or "substantially" that appear in the content of the present case not only cover the explicitly recited numerical values and numerical ranges, but also cover the allowable deviation ranges that can be understood by those with ordinary knowledge in the technical field to which the invention pertains. This deviation range can be determined by the errors generated during measurement, and such errors are, for example, caused by the limitations of both the measurement system and the process conditions. In addition, "about" can mean within one or more standard deviations of the above numerical values, such as within ±30%, ±20%, ±10%, or ±5%. The words such as "about", "approximate", or "substantially" that appear in the text of the present case can select acceptable deviation ranges or standard deviations according to optical properties, etching properties, mechanical properties, or other properties, rather than simply applying a single standard deviation to all properties such as the above optical properties, etching properties, mechanical properties, and other properties.

[0063] Figure 1A is a top view schematic diagram of a transparent display of at least one embodiment of the present invention. Please refer to Figure 1A , the transparent display 100 includes a plurality of light-transmitting blocks 110, a plurality of driving electrode blocks 120, a plurality of horizontal running lines 131, and a plurality of vertical running lines 132. The driving electrode blocks 120, the horizontal running lines 131, and the vertical running lines 132 are all components of the circuit pattern layer of the transparent display 100 and have a relatively low light transmittance. The light transmittance of the driving electrode blocks 120, the horizontal running lines 131, and the vertical running lines 132 can be between 0% and 10%. The light-transmitting blocks 110 have a relatively high light transmittance, for example, between 50% and 95%. Therefore, light (such as visible light) can almost completely penetrate the light-transmitting blocks 110, making the light-transmitting blocks 110 appear transparent in appearance.

[0064] These horizontal running lines 131 extend along multiple parallel horizontal reference lines L1, and these vertical running lines 132 extend along multiple parallel vertical reference lines L2. The horizontal reference lines L1 and the vertical reference lines L2 can be imaginary straight lines, that is, the transparent display 100 may not actually display the horizontal reference lines L1 and the vertical reference lines L2. The extending direction of each horizontal reference line L1 is different from the extending direction of each vertical reference line L2. For Figure 1A example, the horizontal reference lines L1 and the vertical reference lines L2 are perpendicular to each other, and these horizontal reference lines L1 and these vertical reference lines L2 are distributed in a mesh pattern.

[0065] In Figure 1A the illustrated embodiment, multiple horizontal running lines 131 are distributed on one of the horizontal reference lines L1, and multiple vertical running lines 132 are distributed on one of the vertical reference lines L2, wherein these driving electrode blocks 120 are distributed at multiple intersections formed by the intersection of these horizontal reference lines L1 and these vertical reference lines L2. Therefore, these horizontal running lines 131, these vertical running lines 132, and these driving electrode blocks 120 are distributed in a mesh pattern along these horizontal reference lines L1 and these vertical reference lines L2, and these driving electrode blocks 120 are arranged in a matrix.

[0066] In other words, these horizontal running lines 131, these vertical running lines 132, and these driving electrode blocks 120 form a mesh pattern and surround these light-transmitting blocks 110, so that these light-transmitting blocks 110 are located within multiple lattices of the above-mentioned mesh pattern. For Figure 1A example, each light-transmitting block 110 can be surrounded by two horizontal running lines 131, two vertical running lines 132, and four driving electrode blocks 120.

[0067] These driving electrode blocks 120 connect these horizontal running lines 131 and these vertical running lines 132, and each driving electrode block 120 connects two horizontal running lines 131 and two vertical running lines 132, so that each driving electrode block 120 is located between two adjacent horizontal running lines 131 and between two adjacent vertical running lines 132. Therefore, each vertical running line 132 and each horizontal running line 131 are separated by the driving electrode blocks 120.

[0068] Each driving electrode block 120 has at least one first edge 121 and at least one second edge 122, wherein at least one first edge 121 connects one of the horizontal running lines 131 and one of the vertical running lines 132, and at least one second edge 122 connects one of the horizontal running lines 131 and one of the vertical running lines 132. For Figure 1AFor example, each driving electrode block 120 has two opposite first edges 121 and two opposite second edges 122.

[0069] In a single driving electrode block 120, each first edge 121 connects a horizontal trace 131 and a vertical trace 132, and each second edge 122 connects a horizontal trace 131 and a vertical trace 132, where at least one horizontal trace 131 is connected between adjacent first edge 121 and second edge 122, and at least one vertical trace 132 is connected between adjacent first edge 121 and second edge 122.

[0070] Figure 1B is Figure 1A a partial enlarged schematic diagram in. Please refer to Figure 1A and Figure 1B In each driving electrode block 120, at least one first edge 121 extends along a first straight line SL1, and at least one second edge 122 extends along a second straight line SL2, where the first straight line SL1 is not parallel to the second straight line SL2. In this embodiment, each first edge 121 extends along the first straight line SL1, and each second edge 122 extends along the second straight line SL2, where the first straight line SL1 can be perpendicular to the second straight line SL2, and the shapes of both the first edge 121 and the second edge 122 can be substantially straight lines.

[0071] Neither the first straight line SL1 nor the second straight line SL2 is parallel or perpendicular to each horizontal reference line L1 and each vertical reference line L2, so that either the first straight line SL1 or the second straight line SL2 will intersect the horizontal reference line L1 and the vertical reference line L2, and the directions of both the first edge 121 and the second edge 122 of the driving electrode block 120 are neither parallel nor perpendicular to the direction of either the horizontal trace 131 or the vertical trace 132. A first acute angle A1 is formed between the intersecting first straight line SL1 and the horizontal reference line L1, and a second acute angle A2 is formed between the intersecting second straight line SL2 and the horizontal reference line L1. In addition, both the first straight line SL1 and the second straight line SL2 can be imaginary straight lines. That is to say, the transparent display 100 may not actually display the first straight line SL1 and the second straight line SL2.

[0072] Each of the first acute angle A1 and the second acute angle A2 can be between 35 degrees and 55 degrees, for example, 35 degrees or 55 degrees. That is to say, either of the first acute angle A1 and the second acute angle A2 is approximately in the range of 45±5 degrees. In this embodiment, each of the transverse running lines 131 and each of the longitudinal running lines 132 are both in a straight strip shape, wherein each of the transverse running lines 131 has a pair of opposite horizontal line edges 131e, and each of the longitudinal running lines 132 has a pair of opposite vertical line edges 132e. Since each light-transmitting block 110 is surrounded by two transverse running lines 131, two longitudinal running lines 132 and four driving electrode blocks 120, the edge of each light-transmitting block 110 is defined by two horizontal line edges 131e, two vertical line edges 132e, two first edges 121 and two second edges 122.

[0073] Since the directions of both the first edge 121 and the second edge 122 are neither parallel nor perpendicular to the direction of either the transverse running line 131 or the longitudinal running line 132, the geometric pattern surrounded by the edges of each light-transmitting block 110 (equivalent to the first edge 121, the second edge 122, the horizontal line edge 131e and the vertical line edge 132e) is a polygon with more than four sides in terms of the number of side lengths, and all the edges of each light-transmitting block 110 extend along more than three directions. For example, Figure 1B All the edges of the octagonal light-transmitting block 110 shown extend along four directions parallel to the transverse running line 131, the longitudinal running line 132, the first straight line SL1 and the second straight line SL2.

[0074] Since the shape of each light-transmitting block 110 is octagonal, each light-transmitting block 110 has eight interior angles A3, and any interior angle A3 of the geometric pattern (i.e., the octagonal light-transmitting block 110) is greater than or equal to 125 degrees. Among the eight interior angles A3 of each light-transmitting block 110, two of the interior angles A3 are located between the horizontal line edge 131e and the first edge 121, and the other two interior angles A3 are located between the horizontal line edge 131e and the second edge 122.

[0075] In addition, it can be seen from Figure 1B that the interior angle A3 located between the horizontal line edge 131e and the first edge 121 is supplementary to the first acute angle A1, and the interior angle A3 located between the horizontal line edge 131e and the second edge 122 is supplementary to the second acute angle A2. Since each of the first acute angle A1 and the second acute angle A2 can be between 35 degrees and 55 degrees, the interior angle A3 adjacent to the horizontal line edge 131e can be between 125 degrees and 145 degrees, for example, 125 degrees or 145 degrees.

[0076] Each driving electrode block 120 includes a plurality of electrode pads 123 and 124, wherein at least one of these electrode pads 123 and 124 extends along a direction parallel to the first straight line SL1 or the second straight line SL2. For Figure 1B example, each driving electrode block 120 includes four electrode pads 124 and two electrode pads 123, wherein every two of these four electrode pads 124 are oppositely arranged, and these two electrode pads 123 are oppositely arranged with each other.

[0077] Each electrode pad 123 extends along a direction parallel to the first straight line SL1, and each electrode pad 124 extends along a direction parallel to the second straight line SL2. Therefore, in this embodiment, at least two electrode pads, namely electrode pads 123 and 124, respectively extend along directions parallel to the first straight line SL1 and the second straight line SL2, as Figure 1B shown.

[0078] Each driving electrode block 120 further includes a plurality of light-emitting elements 125, wherein these light-emitting elements 125 are disposed on these electrode pads 123 and 124 and are electrically connected to these electrode pads 123 and 124. Each light-emitting element 125 is disposed on two adjacent electrode pads 123 or two adjacent electrode pads 124, and the shape of each light-emitting element 125 is strip-shaped.

[0079] Among the electrode pad 123 and the light-emitting element 125 disposed thereon, the axis 125a of the light-emitting element 125 may not be parallel to the extending direction of the electrode pad 123 (i.e., the extending direction of the first straight line SL1). For example, the axis 125a of the light-emitting element 125 is perpendicular to the extending direction of the electrode pad 123 and parallel to the second straight line SL2. Similarly, among the electrode pad 124 and the light-emitting element 125 disposed thereon, the axis 125a of the light-emitting element 125 may not be parallel to the extending direction of the electrode pad 124 (i.e., the extending direction of the second straight line SL2). For example, the axis 125a of the light-emitting element 125 is perpendicular to the extending direction of the electrode pad 124 and parallel to the first straight line SL1.

[0080] The light-emitting element 125 can be a light-emitting diode (LED), such as a micro light-emitting diode (micro LED) or a mini light-emitting diode (mini LED). These light-emitting elements 125 can emit a single color of light (such as white light or blue light). Alternatively, these light-emitting elements 125 can emit multiple colors of light (such as red light, green light, and blue light). Each driving electrode block 120 further includes a plurality of electronic components (not shown), such as a plurality of thin film transistors (TFTs) and a plurality of passive components. These electronic components are electrically connected and control the light-emitting elements 125 to emit light, so that the transparent display 100 can display an image.

[0081] Each driving electrode block 120 includes a plurality of stacked film layers (not shown), such as a plurality of metal pattern layers, at least one semiconductor pattern layer, a black matrix layer, and a plurality of insulating layers, wherein the aforementioned electronic components are formed by these stacked film layers. The outlines of the driving electrode block 120, the horizontal trace 131, and the vertical trace 132 are jointly defined by the metal pattern layer, the semiconductor pattern layer, and the black matrix layer. Therefore, each driving electrode block 120 has a non-uniform light transmittance, that is, the light transmittances of different parts of the driving electrode block 120 are significantly unequal.

[0082] It should be noted that Figure 1A mainly depicts the outlines of the circuit pattern layers of the transparent display 100, that is, the outlines of the driving electrode block 120, the horizontal trace 131, and the vertical trace 132, and omits the depiction of the plurality of components of the driving electrode block 120, that is, the electrode pads 123, 124, and the light-emitting elements 125, and these components (electrode pads 123, 124, and light-emitting elements 125) of the driving electrode block 120 are only depicted in Figure 1B the figure.

[0083] Figure 1C is Figure 1A a schematic diagram of the diffraction pattern generated by the transparent display in the figure. Please refer to Figure 1C , Figure 1C The diffraction pattern 100p shown is drawn based on the light spot formed by irradiating the transparent display 100 with a beam of light having a certain intensity, where the aforementioned beam of light can be at least one of a light-emitting diode, an incandescent lamp, a mercury lamp, a fluorescent lamp, and a laser. The diffraction pattern 100p is depicted by means of color inversion, so the black blocks presented in the diffraction pattern 100p represent the light spots formed by diffraction. In other words, Figure 1C the light spots constituting the diffraction pattern 100p are depicted in black.

[0084] Please refer to Figure 1A andFigure 1C , the diffraction pattern 100p is mainly formed by the diffraction caused by the contours of the driving electrode block 120, the horizontal trace 131, and the vertical trace 132. In other words, the shape of the diffraction pattern 100p (i.e., the shape and distribution of the light spot) is mainly determined by the contour of the circuit pattern layer of the transparent display 100 (as Figure 1A shown).

[0085] Please refer to Figure 1B and Figure 1C , since the shape of each light-transmitting block 110 is a polygon with more than four sides in terms of the number of side lengths, all the edges of each light-transmitting block 110 will extend along more than three directions. Taking the octagonal light-transmitting block 110 shown in Figure 1B as an example, all the edges of each light-transmitting block 110 extend along four directions parallel to the horizontal trace 131, the vertical trace 132, the first straight line SL1, and the second straight line SL2.

[0086] Thus, the diffraction pattern 100p generated by the transparent display 100 not only extends along the horizontal direction X1 and the vertical direction X2, but also extends along the inclined directions X3 and X4. The inclined directions X3 and X4 are not parallel to each other, and are not parallel to, nor perpendicular to, either the horizontal direction X1 or the vertical direction X2. Therefore, the high-frequency noise of the diffraction pattern 100p will be distributed along the horizontal direction X1, the vertical direction X2, the inclined direction X3, and the inclined direction X4, thereby forming the cross-shaped diffraction pattern 100p as shown in Figure 1C .

[0087] Figure 2A is a top view schematic diagram of the transparent display in the comparative example. Please refer to Figure 2A , the transparent display 200 in the comparative example includes a plurality of cross-shaped light-transmitting blocks 210, a plurality of rectangular blocks 220, and a plurality of traces 230. Among them, these rectangular blocks 220 and these traces 230 are distributed in a mesh pattern and surround these cross-shaped light-transmitting blocks 210, and these rectangular blocks 220 are arranged in a matrix. The light transmittance of the rectangular blocks 220 and the traces 230 is between 0% and 10%, and the light transmittance of the cross-shaped light-transmitting blocks 210 is between 50% and 95%. Therefore, the rectangular blocks 220 and the traces 230 have a low light transmittance, while the cross-shaped light-transmitting blocks 210 have a high light transmittance.

[0088] Figure 2B is Figure 2A the schematic diagram of the diffraction pattern generated by the transparent display in Figure 2B . Please refer to Figure 2BThe diffraction pattern 200p shown is also drawn based on the light spot formed by irradiating the transparent display 200 with a light beam having a relatively high intensity, where the above light beam can be at least one of a light-emitting diode, an incandescent lamp, a mercury lamp, a fluorescent lamp, and a laser. In addition, the diffraction pattern 200p is depicted by means of color inversion, so Figure 2B the light spots constituting the diffraction pattern 200p are also depicted in black.

[0089] Please refer to Figure 2A and Figure 2B , in the transparent display 200 of the comparative example, all the edges of each cross-shaped light-transmitting block 210 extend only along two directions. Taking Figure 2A as an example, the edges of the cross-shaped light-transmitting block 210 extend along a first direction D1 and a second direction D2, where the first direction D1 is parallel to the horizontal reference line L1 (please refer to Figure 1A ), and the second direction D2 is parallel to the vertical reference line L2 (please refer to Figure 1A ). Therefore, the diffraction pattern 200p generated by the transparent display 200 mainly extends along the horizontal direction X1 and the vertical direction X2, so that the high-frequency noise of the diffraction pattern 200p is only concentratedly distributed along the horizontal direction X1 and the vertical direction X2, thereby forming a cross-shaped diffraction pattern 200p as shown in Figure 2B .

[0090] Please refer to Figure 1C and Figure 2B . By comparing the diffraction pattern 100p of this embodiment with the diffraction pattern 200p of the comparative example, it can be seen that the high-frequency noise of the diffraction pattern 200p of the comparative example is mainly distributed along two directions (the first direction D1 and the second direction D2), while the high-frequency noise of the diffraction pattern 100p of this embodiment is obviously distributed along more than three directions (for example, four directions parallel to the horizontal trace line 131, the vertical trace line 132, the first straight line SL1, and the second straight line SL2).

[0091] It can be seen from this that compared with the diffraction pattern 200p of the comparative example, the high-frequency noise of the diffraction pattern 100p of this embodiment is more dispersed, so that the transparent display 100 of this embodiment has a relatively low high-frequency noise intensity and can achieve better image quality than the transparent display 200 of the comparative example. Therefore, these light-transmitting blocks 110 in this embodiment can reduce the influence of light diffraction on the transparent display 100, thereby improving the image quality of the transparent display 100.

[0092] Figure 3 is a top view schematic diagram comparing Figure 1B and Figure 2A the circuit patterns of the two, where Figure 3The outlines 120c of two driving electrode blocks 120 (depicted by solid lines) and the outlines 220c of two rectangular blocks 220 (depicted by dashed lines) are depicted, and these outlines 120c respectively overlap these outlines 220c. Secondly, Figure 3 It is drawn under the condition that the driving electrode block 120 and the rectangular block 220 have the same size (for example, the same area and the same side lengths). Therefore, the outline 120c can be drawn by rotating the outline 220c.

[0093] Figure 3 It is also based on Figure 1A the horizontal trace lines 131, the vertical trace lines 132 in Figure 2A and the trace lines 230 in Figure 3 to depict the mesh pattern 330.

[0094] Please refer to Figure 3 , the part of the mesh pattern 330 within the outlines 120c and 220c forms a cross pattern, where this cross pattern defines four quadrants. In Figure 3 , the first quadrant (located in the upper right of the cross pattern) defined by the upper cross pattern contains a large triangular region A31 and two small triangular regions A32, where the large triangular region A31 is marked by a slanted region and the small triangular regions A32 are marked by a dotted region.

[0095] The large triangular region A31 and the small triangular regions A32 are regions where the region within the outline 120c, the region within the outline 220c, and the mesh pattern 330 do not overlap with each other. Specifically, the large triangular region A31 represents the part of the rectangular block 220 that does not overlap with the driving electrode block 120 and the mesh pattern 330, and the small triangular regions A32 represent the part of the driving electrode block 120 that does not overlap with the rectangular block 220 and the mesh pattern 330.

[0096] From Figure 3It can be known that under the condition that the driving electrode block 120 and the rectangular block 220 have the same size, the overlapping area between the driving electrode block 120 (i.e., the area within the contour 120c) and the mesh pattern 330 is larger than the overlapping area between the rectangular block 220 (i.e., the area within the contour 220c) and the mesh pattern 330. As a result, the area of a single large triangular region A31 is not only larger than the area of a single small triangular region A32, but also larger than the total area of two small triangular regions A32.

[0097] From this, it can be seen that compared with the rectangular block 220 of the comparative example, the driving electrode block 120 of this embodiment occupies less area in the region outside the mesh pattern 330, so that the size (such as the area) of each light-transmitting block 110 in this embodiment is larger than the size (such as the area) of each cross-shaped light-transmitting block 210 in the comparative example. In this way, under the condition that the driving electrode block 120 and the rectangular block 220 have the same size, the aperture ratio and the overall light transmittance of the transparent display 100 of this embodiment are both greater than those of the transparent display 200 of the comparative example.

[0098] Figure 4A is a top view schematic diagram of a transparent display according to at least one embodiment of the present invention, and Figure 4B is Figure 4A a partial enlarged schematic diagram in Figure 4A and Figure 4B . Referring to

[0099] and

[0100] Figure 4B The transparent display 400 of this embodiment is similar to the transparent display 100 of the foregoing embodiment. For example, the transparent display 400 includes a plurality of light-transmitting blocks 410, a plurality of driving electrode blocks 420, a plurality of horizontal trace lines 431, and a plurality of vertical trace lines 432.

[0099] These horizontal trace lines 431 extend along these horizontal reference lines L1, and these vertical trace lines 432 extend along these vertical reference lines L2, so that the horizontal trace lines 431, the vertical trace lines 432, and the driving electrode blocks 420 are distributed in a mesh pattern along the horizontal reference lines L1 and the vertical reference lines L2. Secondly, each driving electrode block 420 also has two opposite first edges 121 and two opposite second edges 122. Each horizontal trace line 431 has a pair of opposite horizontal line edges 131e, and each vertical trace line 432 has a pair of opposite vertical line edges 132e.

[0100] The following mainly describes the differences between the transparent displays 100 and 400, and basically does not repeat the same features of the transparent displays 100 and 400. Specifically, different from the transparent display 100 of the foregoing embodiment, in the transparent display 400 of the present embodiment, a curved edge C4 is formed between the edge of one of the horizontal running lines 431 and the vertical running lines 432 and the edge of the driving electrode block 420 connected thereto.

[0101] Take Figure 4B as an example. Each first edge 121 connects a horizontal line edge 131e and a vertical line edge 132e, and each second edge 122 also connects a horizontal line edge 131e and a vertical line edge 132e. Among the connected vertical line edge 132e, the first edge 121 and the horizontal line edge 131e, two curved edges C4 are respectively formed between the vertical line edge 132e and the first edge 121, and between the horizontal line edge 131e and the first edge 121. Similarly, among the connected vertical line edge 132e, the second edge 122 and the horizontal line edge 131e, the other two curved edges C4 are respectively formed between the vertical line edge 132e and the second edge 122, and between the horizontal line edge 131e and the second edge 122.

[0102] These curved edges C4 can be formed through the black matrix layer. That is to say, the curved edge C4 can be the edge of the black matrix layer. The shape of the light-transmitting block 410 is similar to an octagon, and these curved edges C4 can make the shape of the light-transmitting block 410 become a rounded octagon, so that the shape of each light-transmitting block 410 is approximately circular, as Figure 4A shown in Figure 4B .

[0103] Figure 4C FIG. Figure 4A is a schematic diagram of the diffraction pattern generated by the transparent display in Figure 4C , wherein Figure 1C is drawn in the same way as Figure 4C , and Figure 1C the method for forming the diffraction pattern 400p in Figure 4A is also the same as the method for forming the diffraction pattern 100p in Figure 4C . Please refer to Figure 1C and . Since the shape of each light-transmitting block 410 is approximately circular, the diffraction pattern 400p generated by the transparent display 400 not only extends along the four directions of the horizontal direction X1, the vertical direction X2, the inclined directions X3 and X4, but also, compared with Figure 1C the diffraction pattern 100p of , the diffraction pattern 400p has a shorter length in these four directions, so that the light spots of the diffraction pattern 400p are mostly concentrated in the center. Therefore, the transparent display 400 allows more zero-order light to pass through.

[0104] It can be seen therefrom that the high-frequency noise of the diffraction pattern 400p is more dispersed, and the transparent display 400 can allow more zero-order light to pass through. Therefore, by using these curved edges C4, the transparent display 400 of this embodiment has a lower high-frequency noise intensity, so that these light-transmitting blocks 410 can effectively reduce the influence of light diffraction on the transparent display 400, thereby improving the image quality.

[0105] Figure 5A It is a top view schematic diagram of a transparent display according to at least one embodiment of the present invention. Please refer to Figure 5A , the transparent display 500 of this embodiment is similar to the transparent display 100 of the foregoing embodiment. For example, the transparent display 500 also includes a plurality of driving electrode blocks 120. The following mainly describes the differences between the transparent displays 100 and 500, and basically does not repeat the same features of the transparent displays 100 and 500.

[0106] Different from the transparent display 100, the transparent display 500 further includes a plurality of horizontal traces 531a, 531b, a plurality of vertical traces 532a, 532b, and a plurality of light-transmitting blocks 511 and 512, wherein at least one of these horizontal traces 531a and 531b has a curved or polyline shape, and at least one of these vertical traces 532a and 532b has a curved or polyline shape. Taking Figure 5A as an example, each of the horizontal traces 531a and 531b is a curve or a polyline, and each of the vertical traces 532a and 532b is a curve or a polyline, as shown in Figure 5A .

[0107] The horizontal traces 531a and 531b are different from each other, and the vertical traces 532a and 532b are different from each other. In the embodiment shown in Figure 5A , the upper edge and the lower edge of the horizontal trace 531a are respectively a concave edge and a convex edge, and the lower edge and the upper edge of the horizontal trace 531b are respectively a concave edge and a convex edge. Similarly, the right edge and the left edge of the vertical trace 532a are respectively a concave edge and a convex edge, and the left edge and the right edge of the vertical trace 532b are respectively a concave edge and a convex edge.

[0108] These horizontal traces 531a, 531b extend along the horizontal reference line L1, and these vertical traces 532a, 532b extend along the vertical reference line L2. However, these horizontal traces 531a and 531b are more staggered along the horizontal reference line L1, and these vertical traces 532a and 532b are more staggered along the vertical reference line L2, thereby forming light-transmitting blocks 511 and 512 with different shapes.

[0109] The edges of at least one of these light-transmitting blocks 511 and 512 will form an X shape, and the X shape extends along a direction parallel to the first straight line SL1 and a direction parallel to the second straight line SL2. For Figure 5A example, the shape of each light-transmitting block 511 is an X shape, and the X-shaped light-transmitting block 511 extends along a direction parallel to the first straight line SL1 and a direction parallel to the second straight line SL2. In addition, different from the X-shaped light-transmitting block 511, the shape of each light-transmitting block 512 is close to a rounded rectangle, as Figure 5A shown.

[0110] Figure 5B is Figure 5A a schematic diagram of the diffraction pattern generated by the transparent display in Figure 5B , and the drawing method of Figure 1C is the same as that of Figure 5B , and the method for forming the diffraction pattern 500p in Figure 1C is also the same as the method for forming the diffraction pattern 100p in Figure 5A and Figure 5B . Referring to

[0111] and Figure 4A , since the shape of each light-transmitting block 511 is an X shape and the shape of each light-transmitting block 512 is close to a rounded rectangle, the diffraction pattern 500p generated by the transparent display 500 basically extends along the inclined directions X3 and X4. Secondly, most of the light spots of the diffraction pattern 500p are concentrated in the center, so the transparent display 500 can allow more zero-order light to pass through and disperse the high-frequency term noise to reduce the high-frequency term noise intensity, thereby achieving better image quality.

[0111] It is worth mentioning that Figure 4A the horizontal running lines 431 and the vertical running lines 432 in Figure 5A can be replaced by the horizontal running lines 531a, 531b and the vertical running lines 532a, 532b in Figure 5A . In other words, Figure 4A the transparent display 500 in Figure 4B can also have a curved edge C4 as shown in

[0112] Figure 6 to more disperse the high-frequency term noise and further improve the image quality.

[0112] Figure 6 is a top view schematic diagram of a transparent display according to another embodiment of the present invention. Referring to Figure 6 , the transparent display 600 of this embodiment includes a plurality of light-transmitting blocks 110, a plurality of driving electrode blocks 620, a plurality of horizontal running lines 131 and a plurality of vertical running lines 132. The contour of the driving electrode block 620 is the same as the contour of the driving electrode block 120, so the transparent display 600 also includes these octagonal light-transmitting blocks 110.

[0113] The transparent display 600 is similar to the transparent display 100 of the foregoing embodiment. The difference between the transparent display 600 and 100 is only that the electrode pads of the driving electrode blocks 620 and 120 are differently arranged. Specifically, Figure 6 The shown driving electrode block 620 includes a plurality of electrode pads 124 and a plurality of light-emitting elements 125, but does not include the electrode pad 123 as shown in Figure 1B Therefore, all the electrode pads 124 of each driving electrode block 620 extend along a direction parallel to the second straight line SL2.

[0114] These light-emitting elements 125 are respectively arranged on these electrode pads 124 and are electrically connected to these electrode pads 124, wherein the axis 125a of each light-emitting element 125 is not parallel to the extending direction of the electrode pad 124 (i.e., the extending direction of the second straight line SL2). For example, the axis 125a is perpendicular to the extending direction of the electrode pad 124. In the Figure 6 shown embodiment, the axis 125a of each light-emitting element 125 can be parallel to the extending direction of the first straight line SL1.

[0115] Figure 7 is a top view schematic diagram of a transparent display according to another embodiment of the present invention. Please refer to Figure 7 , the transparent display 700 of this embodiment includes a plurality of light-transmitting blocks 110, a plurality of driving electrode blocks 720, a plurality of horizontal running lines 131 and a plurality of vertical running lines 132. The contour of the driving electrode block 720 is the same as the contours of the driving electrode blocks 120 and 620. Therefore, the transparent display 700 also includes these octagonal light-transmitting blocks 110.

[0116] The transparent display 700 is similar to the transparent display 600 of the foregoing embodiment. For example, Figure 7 the shown driving electrode block 720 includes a plurality of electrode pads 124 and a plurality of light-emitting elements 125, wherein these light-emitting elements 125 are respectively arranged on these electrode pads 124 and are electrically connected to these electrode pads 124. The difference between the transparent display 700 and 600 is only that the arrangements of the light-emitting elements 125 of the driving electrode blocks 720 and 620 are different.

[0117] Specifically, in the transparent display 700, the axis 125a of each light-emitting element 125 is parallel to the longitudinal reference line L2 and perpendicular to the transverse reference line L1. Therefore, the axis 125a is not parallel to either the first straight line SL1 or the second straight line SL2, nor is it perpendicular to either the first straight line SL1 or the second straight line SL2.

[0118] It should be particularly mentioned that Figure 6 and Figure 7The arrangements of the disclosed electrode pads 123, 124 and light-emitting elements 125 can be applied to Figure 4B the transparent display 400 and Figure 5A the transparent display 500. Specifically, Figure 4B at least one driving electrode block 420 in Figure 6 can be replaced with the driving electrode block 620 in Figure 7 or the driving electrode block 720 in Figure 5A and at least one driving electrode block 120 in Figure 6 can be replaced with the driving electrode block 620 in Figure 7 or the driving electrode block 720 in Figure 6 or Figure 7 the arrangements of the electrode pads 123, 124 and light-emitting elements 125.

[0119] In summary, since the first edge and the second edge of each driving electrode block extend along the first straight line and the second straight line respectively, and the directions of the first edge and the second edge are neither parallel nor perpendicular to the direction of any of the horizontal trace lines and the vertical trace lines, all the edges of each light-transmitting block will extend along more than three (e.g., four) directions to reduce the high-frequency term noise intensity, thereby improving the image quality.

[0120] Although the present invention has been disclosed as above by way of embodiments, it is not intended to limit the present invention. Those with ordinary knowledge in the technical field to which the present invention pertains may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to that defined by the appended patent application scope.
