Description

Technical Field

[0001] The invention relates to a curved display device, and in particular to a curved display device comprising a plurality of non-rectangular substrates. Background Art

[0002] With the development of the technology industry, display devices have been widely used in daily life. By splicing multiple display units (light panels) containing light-emitting components on a curved surface, curved display devices can provide an experience different from that of flat displays and are often used in large-scale display activities. Since the display surface of a curved display device is non-planar, the shape of the light panel may be a non-rectangular polygon with oblique edges. Taking a spherical display device as an example, the shape of the light panel close to the equator may be a trapezoid, while the shape of the light panel close to the north and south poles may be a special-shaped panel with a pentagon or larger.

[0003] However, if the light-emitting components are arranged on a non-rectangular polygonal light board with beveled edges in the same manner as they are generally arranged on a rectangular light board, the distances from the light-emitting components located near the edges of the light board to the beveled edges of the light board may be different, resulting in bright or dark lines at the joints, thereby affecting the display quality.

[0060] In the following text, in order to clearly present the technical features of the present invention, the dimensions (e.g., length, width, thickness, and depth) of the components (e.g., layers, films, substrates, and regions, etc.) in the drawings will be enlarged in unequal proportions, and the number of some components will be reduced. Therefore, the description and explanation of the embodiments below are not limited to the number of components in the drawings and the dimensions and shapes presented by the components, but should cover the dimensions, shapes, and deviations thereof caused by the actual process and / or tolerances. For example, the flat surface shown in the drawings may have rough and / or nonlinear features, and the acute angles shown in the drawings may be rounded. Therefore, the components presented in the drawings of the present invention are mainly for illustration, and are not intended to accurately depict the actual shape of the components, nor are they intended to limit the scope of the patent application of the present invention.

[0061] Secondly, the words "about", "approximately" or "substantially" used in the present invention not only cover the numerical values ​​and numerical ranges clearly recorded, but also cover the permissible deviation range that can be understood by a person with ordinary knowledge in the technical field to which the invention belongs, wherein the deviation range can be determined by the error generated during measurement, and the error is caused by the limitation of the measurement system or process conditions, for example. For example, two objects (such as the planes or traces of the substrate) are "substantially parallel" or "substantially perpendicular", wherein "substantially parallel" and "substantially perpendicular" respectively represent that the parallelism and perpendicularity between the two objects may include the non-parallelism and non-perpendicularity caused by the permissible deviation range.

[0062] In addition, "approximately" may mean within one or more standard deviations of the above values, such as ±30%, ±20%, ±10% or ±5%. The words "approximately", "approximately" or "substantially" used in the present invention may be selected based on the optical properties, etching properties, mechanical properties or other properties to select an acceptable deviation range or standard deviation, rather than applying a single standard deviation to all properties such as the above optical properties, etching properties, mechanical properties and other properties.

[0063] The spatially relative terms used in the present invention, such as "below", "under", "above", "on", etc., are for the purpose of facilitating the description of the relative relationship between one component or feature and another component or feature, as shown in the figure. The true meaning of these spatially relative terms includes other orientations. For example, when the figure is flipped up and down 180 degrees, the relationship between one component and another component may change from "below" or "under" to "above" or "on". In addition, the spatially relative descriptions used in the present invention should also be interpreted in the same way.

[0064] It should be understood that, although the present invention may use terms such as "first", "second", "third" to describe various components or signals, these components or signals should not be limited by these terms. These terms are mainly used to distinguish one component from another component, or one signal from another signal. In addition, the term "or" used in the present invention may include any one or more combinations of the associated listed items depending on the actual situation.

[0065] In addition, the present invention may be implemented or applied through other different specific embodiments, and the details of the present invention may also be combined, modified and changed in various embodiments based on different viewpoints and applications without departing from the concept of the present invention.

[0066] Figure 1 is a schematic diagram of a curved display device according to at least one embodiment of the present invention. Figure 2 yes Figure 1 The enlarged partial diagram of the curved display screen shown in Figure 1 and Figure 2 The curved display device 10 includes a curved display screen 11 . The curved display screen 11 has a display surface DS, which is a concave curved surface of the curved display device 10 . The curved display screen 11 includes a plurality of display units 100 .

[0067] Figure 3A yes Figure 2 Magnified schematic diagram of area A in the figure. Figure 3A The curved display screen 11 further includes a bracket 200 , and the display units 100 are spliced ​​and disposed on the bracket 200 .

[0068] Figure 3B yes Figure 3A See the schematic diagram of the display unit shown. Figure 3B The display unit 100 includes a non-rectangular substrate 110 and a pixel array 120 disposed on the non-rectangular substrate 110. Since the curved display device 10 includes multiple display units 100, the curved display device 10 includes multiple non-rectangular substrates 110 and multiple pixel arrays 120, and these pixel arrays 120 are respectively disposed on these non-rectangular substrates 110.

[0069] like Figure 3B As shown, the non-rectangular substrate 110 has a first side S1, a second side S2 connected to the first side S1, and a third side S3 opposite to the first side S1. The pixel array 120 includes a plurality of light-emitting pixels 121 arranged in rows and columns, and the light-emitting pixels 121 are arranged into a plurality of pixel rows and a plurality of pixel columns, and the pixel rows include a first edge pixel row C1 adjacent to the first side S1 and a second edge pixel row C2 adjacent to the third side S3, and the pixel columns include a first edge pixel row R1 adjacent to the second side S2.

[0070] The distances L1 from these light-emitting pixels 121 of the first edge pixel row C1 to the first side S1 are all equal, the distances L1 from these light-emitting pixels 121 of the second edge pixel row C2 to the third side S3 are all equal, the distances L2 from these light-emitting pixels 121 of the first edge pixel column R1 to the second side S2 are all equal, and the distance L1 from these light-emitting pixels 121 of the first edge pixel row C1 to the first side S1 is equal to the distance L1 from these light-emitting pixels 121 of the second edge pixel row C2 to the third side S3.

[0071] Through the above design, when two adjacent non-rectangular substrates are spliced, the distances from the luminous pixels of the edge pixel rows of one of the two adjacent non-rectangular substrates adjacent to the splicing edge to the luminous pixels of the edge pixel rows of the other two adjacent non-rectangular substrates adjacent to the splicing edge are all equal, which can reduce the generation of bright lines or dark lines at the splicing point, thereby maintaining or improving the display quality.

[0072] For example, when the first side S1 of the non-rectangular substrate 110 is spliced ​​to the third side S3 of another non-rectangular substrate 110, the distances L1 from the first edge pixel row C1 adjacent to the first side S1 to the first side S1 are all equal, and the distances L1 from the second edge pixel row C2 adjacent to the third side S3 to the third side S3 are all equal.

[0073] Therefore, the distances from the light-emitting pixels 121 of the first edge pixel row C1 adjacent to the first side S1 to the light-emitting pixels 121 of the second edge pixel row C2 adjacent to the third side S3 are also equal, so the bright or dark lines at the joints can be reduced, thereby maintaining or improving the display quality.

[0074] Please continue reading Figure 3B The non-rectangular substrate 110 further has a fourth side S4 connected to the first side S1, and these pixel rows further include a second edge pixel row R2 adjacent to the fourth side S4, and the distances L2 from these light-emitting pixels 121 of the second edge pixel row R2 to the fourth side S4 are all equal, and the distances L2 from these light-emitting pixels 121 of the second edge pixel row R2 to the fourth side S4 are equal to the distances L2 from these light-emitting pixels 121 of the first edge pixel row R1 to the second side S2.

[0075] Through the above design, when two adjacent non-rectangular substrates are spliced, the distances from the luminous pixels of the edge pixel column of one of the two adjacent non-rectangular substrates adjacent to the splicing edge to the luminous pixels of the edge pixel column of the other two adjacent non-rectangular substrates adjacent to the splicing edge are equal, which can reduce the generation of bright lines or dark lines at the splicing point, thereby maintaining or improving the display quality.

[0076] For example, when the second side S2 of the non-rectangular substrate 110 is spliced ​​to the fourth side S4 of another non-rectangular substrate 110, the distances L2 from the light-emitting pixels 121 of the first edge pixel row R1 adjacent to the second side S2 to the second side S2 are all equal, and the distances L2 from the light-emitting pixels 121 of the second edge pixel row R2 adjacent to the fourth side S4 to the fourth side S4 are all equal.

[0077] Therefore, the distances from the light-emitting pixels 121 of the first edge pixel row R1 adjacent to the second side S2 to the light-emitting pixels 121 of the second edge pixel row R2 adjacent to the fourth side S4 are also equal, so the bright or dark lines at the joints can be reduced, thereby maintaining or improving the display quality.

[0078] In some embodiments, the distance L1 from the light-emitting pixels 121 of the first edge pixel row C1 to the first side S1 may be equal to or different from the distance L2 from the light-emitting pixels 121 of the first edge pixel column R1 to the second side S2. With the above design, the cutting angle of the display unit 100 can be flexibly adjusted.

[0079] In addition, if Figure 3B As shown, the intervals P1 between the light-emitting pixels 121 in the same pixel row (eg, the first edge pixel row R1 ) are all equal, and the intervals P3 between the light-emitting pixels 121 in the same pixel row (eg, the first edge pixel row C1 ) are all equal.

[0080] These pixel columns include two adjacent pixel columns (for example, a first edge pixel column R1 and a pixel column Ra adjacent to the first edge pixel column R1), and a spacing P1 between these light-emitting pixels 121 in one of the two adjacent pixel columns (for example, the first edge pixel column R1) is not equal to a spacing P2 between these light-emitting pixels 121 in the other of the two adjacent pixel columns (for example, the pixel column Ra adjacent to the first edge pixel column R1).

[0081] In addition, the pitch P3 between the light-emitting pixels 121 in any one of the pixel rows (eg, the first edge pixel row C1 ) is equal to the pitch P4 between the light-emitting pixels 121 in the other of the pixel rows (eg, the second edge pixel row C2 ).

[0082] like Figure 3B As shown, the distance L1 between the light-emitting pixels 121 of the first edge pixel row C1 and the first side S1 is the shortest distance between the geometric center of the light-emitting pixel 121 and the first side S1. In other words, it is also the line connecting the geometric centers of the light-emitting pixels 121 parallel to the first side S1 (i.e. Figure 3B The shortest distance from the first side S1 to the first side S2 is shown in dashed line.

[0083] Similarly, the distance L1 from the light-emitting pixels 121 of the second edge pixel row C2 to the third side S3 is the shortest distance from the geometric center of the light-emitting pixel 121 to the third side S3. In other words, it is also the line connecting the geometric centers of the light-emitting pixels 121 parallel to the third side S3 (i.e. Figure 3B The shortest distance from the third side S3 to the dashed line shown.

[0084] The distance L2 from the light-emitting pixels 121 of the first edge pixel row R1 to the second side S2 is the shortest distance from the geometric center of the light-emitting pixel 121 to the second side S2. In other words, it is also the line connecting the geometric centers of the light-emitting pixels 121 parallel to the second side S2 (i.e. Figure 3B The distance L2 from the light-emitting pixels 121 of the second edge pixel row R2 to the fourth side S4 is the shortest distance from the geometric center of the light-emitting pixels 121 to the fourth side S4. In other words, it is also the line connecting the geometric centers of the light-emitting pixels 121 parallel to the fourth side S4 (i.e. Figure 3B The shortest distance from the fourth side S4 to the dashed line shown.

[0085] In addition, if Figure 3B As shown, the spacing P3 between these light-emitting pixels 121 in the same pixel row (for example, the first edge pixel row C1) is the shortest distance (i.e., the vertical distance) between the geometric centers of two adjacent aforementioned light-emitting pixels 121, and the spacing P1 between these light-emitting pixels 121 in the same pixel column (for example, the first edge pixel column R1) is the shortest distance (i.e., the horizontal distance) between the geometric centers of two adjacent aforementioned light-emitting pixels 121.

[0086] In some embodiments, a single light-emitting pixel 121 may include a plurality of light-emitting components, for example, three light-emitting components, and the three light-emitting components may be a red light-emitting component, a green light-emitting component, and a blue light-emitting component, respectively, but the present invention is not limited thereto.

[0087] The light emitting component may be a light emitting diode (LED), for example, a sub-millimeter light emitting diode (mini LED) or a micro LED (micro LED, μLED).

[0088] In addition, the light emitting component may also be a large-sized regular LED other than sub-millimeter LED and micro LED, so the light emitting component is not limited to a smaller-sized sub-millimeter LED or micro LED.

[0089] Please continue reading Figure 3BThe shape of the non-rectangular substrate 110 is a trapezoid. That is, the second side S2 and the fourth side S4 are respectively the upper and lower bases of the trapezoid, and the first side S1 and the third side S3 are respectively the two sides of the trapezoid, but the present invention is not limited thereto.

[0090] Figure 3C is a schematic diagram of a display unit according to at least another embodiment of the present invention. Figure 3C , Figure 3C Examples and Figure 3B Most of the component structures and relative positional relationships of the embodiments are the same, so the same technical features will not be repeated here. The differences between the two embodiments are Figure 3C The first side S1 and the third side S3 of the non-rectangular substrate 110A are arcs.

[0091] Therefore, if Figure 3C As shown, the distance L1 between the light-emitting pixels 121 of the first edge pixel row C1 and the first side S1 is the geometric center line of the light-emitting pixels 121 and the first side S1 having the same curvature (ie Figure 3C The shortest distance from the first side S1 to the first side S2 is shown in dashed line.

[0092] Similarly, the distance L1 between the light-emitting pixels 121 of the second edge pixel row C2 and the third side S3 is the distance between the geometric center lines of the light-emitting pixels 121 and the third side S3 having the same curvature (ie Figure 3C The shortest distance from the third side S3 to the dashed line shown.

[0093] In addition, the pitch P3 between the light-emitting pixels 121 in the same pixel row (eg, the first edge pixel row C1 ) is the shortest distance (ie, vertical distance) between the geometric centers of two adjacent light-emitting pixels 121 .

[0094] Figure 4A yes Figure 2 Magnified schematic diagram of area B in the figure. Figure 4A , these display units 100 are spliced ​​and arranged on a bracket 200. In addition, as Figure 2 As shown, region B is closer to the pole than region A, so Figure 4A The display unit 100 in the embodiment includes, in addition to the trapezoidal shape, a pentagonal display unit 100 formed by splicing the trapezoidal display units 100 below.

[0095] Figure 4B yes Figure 4A See the schematic diagram of the display unit shown. Figure 4B , Figure 4B Examples and Figure 3B Most of the component structures and relative positional relationships of the embodiments are the same, so the same technical features will not be repeated here. The differences between the two embodiments are Figure 4BThe shape of the non-rectangular substrate 110B is a pentagon.

[0096] like Figure 4B As shown, the non-rectangular substrate 110B further has a fifth side S5 connecting the second side S2 and the third side S3, and these pixel rows further include a third edge pixel row R3 adjacent to the fifth side S5, and the distances L2 from these light-emitting pixels 121 of the third edge pixel row R3 to the fifth side S5 are all equal, and the distances L2 from these light-emitting pixels 121 of the third edge pixel row R3 to the fifth side S5 are equal to the distances L2 from these light-emitting pixels 121 of the first edge pixel row R1 to the second side S2.

[0097] The distance L2 from the light-emitting pixels 121 of the third edge pixel row R3 to the fifth side S5 is the shortest distance from the geometric center of the light-emitting pixel 121 to the fifth side S5. In other words, it is also the distance between the geometric center of the light-emitting pixel 121 parallel to the fifth side S5 (i.e. Figure 4B The shortest distance from the fifth side S5 to the fifth side S5 is shown in dashed line.

[0098] In some embodiments, the angle between the fifth side S5 and the second side S2 is greater than 90 degrees and less than 180 degrees. In other words, the angle between the geometric center line of the light-emitting pixels 121 of the third edge pixel row R3 parallel to the fifth side S5 and the geometric center line of the light-emitting pixels 121 of the first edge pixel row R1 parallel to the second side S2 is also greater than 90 degrees and less than 180 degrees.

[0099] In addition, the spacing between the light-emitting pixels 121 in one of the two pixel rows is not equal to the spacing between the light-emitting pixels 121 in the other of the two pixel rows.

[0100] Figure 4C is a schematic diagram of a display unit according to at least another embodiment of the present invention. Figure 4C Examples and Figure 3B Most of the component structures and relative positional relationships of the embodiments are the same, so the same technical features will not be repeated here. The differences between the two embodiments are Figure 4C The shape of the non-rectangular substrate 110C is hexagonal.
