Description

Technical Field

[0001] This invention relates to a display panel. Background Technology

[0002] Modern LED display panels use a timing controller (TCON) to divide the boundary frame of each (or group of) LED using horizontal and vertical lines, serving as the smallest unit of the display. This division method works fine in typical rectangular displays, but in non-rectangular displays (such as parallelograms, polygons, circles, etc.), it can easily cause LEDs to misalign with the boundary frame, resulting in a mismatch between the LEDs and the boundary frame. Summary of the Invention

[0003] One technical embodiment of the present invention is a display panel.

[0004] According to one embodiment of the present invention, a display panel includes a substrate and a timing calculator. The substrate includes a plurality of light-emitting diode (LED) light sources, wherein the LED light sources are arranged in multiple columns, rows, or rings, and the columns, rows, or rings are parallel to a first edge of the substrate, or the columns are parallel to the tangential direction of the first edge, and the first edge of the substrate extends along a first direction. The timing calculator defines a plurality of boundary frames on the substrate, and the boundary frames respectively surround the LED light sources, wherein the boundary frames of two adjacent columns, two adjacent rows, or two adjacent rings are offset in the first direction, or the boundary frames of two adjacent columns are offset in the tangential direction.

[0005] In one embodiment of the present invention, the top view of the substrate is a parallelogram shape, and the first direction is either a horizontal or a vertical direction.

[0006] In one embodiment of the invention, a portion of the light-emitting diode light source is adjacent to the first edge of the substrate, and the edges of each of the boundary frames surrounding the portion of the light-emitting diode light source overlap with the first edge of the substrate.

[0007] In one embodiment of the invention, the substrate has a second edge adjacent to a first edge, the second edge extending along a second direction and the first direction forming an acute angle with the second direction, a portion of a light-emitting diode light source being adjacent to the second edge of the substrate, and the edges of each of the boundary frames surrounding the portion of the light-emitting diode light source overlapping the second edge of the substrate.

[0008] In one embodiment of the present invention, the top view shape of the boundary frame surrounding the portion of the light-emitting diode light source is a right trapezoid, and the remaining portion of the boundary frame is a rectangle.

[0009] In one embodiment of the invention, the substrate has a second edge adjacent to a first edge, the second edge extending along a second direction and forming an obtuse angle with the first edge, a portion of a light-emitting diode light source being adjacent to the second edge of the substrate, and the edges of each of the boundary frames surrounding the portion of the light-emitting diode light source overlapping the second edge of the substrate.

[0010] In one embodiment of the present invention, the substrate has a circular shape when viewed from above.

[0011] In one embodiment of the present invention, the tangent direction is the horizontal direction parallel to the diameter.

[0012] In one embodiment of the present invention, a portion of the light-emitting diode light source is adjacent to a first edge of the substrate, and the edges of each of the boundary frames surrounding the portion of the light-emitting diode light source are arc-shaped.

[0013] In one embodiment of the present invention, the first direction is the circumferential direction.

[0014] In one embodiment of the present invention, the top view of the substrate is polygonal.

[0015] In the above embodiments of the present invention, when the timing calculator defines multiple boundary frames for the substrate, there is an offset between the boundary frames of two adjacent columns or two adjacent rows. Therefore, non-rectangular displays can use this offset to fine-tune the position of the boundary frames, so that the position of the light-emitting diodes matches the shape of the substrate. The boundary frames correspond to the positions of the light-emitting diodes (LEDs), thus preventing the phenomenon of mismatch between the boundary frames and the positions of the LEDs. This provides greater flexibility in the selection of substrates of different shapes, enhancing product competitiveness. Attached Figure Description

[0037] Figure 1 A schematic diagram illustrating a display panel 100 according to an embodiment of the present invention is shown. (Refer to...) Figure 1A display panel 100 includes a substrate 110 and a timing controller (TCON) 120 electrically connected to the substrate 110. The timing controller 120 can be externally connected to the substrate 110 or internally integrated into the substrate 110. The substrate 110 includes a plurality of light-emitting diode (LED) light sources 112. In this embodiment, the LED light sources 112 are arranged in multiple columns, and the columns are parallel to a first edge E1 of the substrate 110, which extends along a first direction D1. In this embodiment, the first edge E1 is a horizontal edge. The timing controller 120 defines a plurality of boundary frames 114 around the substrate 110, and the boundary frames 114 surround the LED light sources 112 respectively, wherein the boundary frames 114 of adjacent columns or adjacent rows have an offset d in the first direction D1. The function of the boundary frame 114 is to allow the timing calculator 120 to control the brightness of the LED light source 112 within each boundary frame 114, enabling local dimming on the irregularly shaped substrate (such as substrate 110) to achieve uniform brightness across the entire display. In some embodiments, a boundary frame 114 surrounds one LED light source 112, thereby improving resolution. However, in other embodiments, a boundary frame 114 may surround multiple LED light sources 112, thereby reducing the computational load on the timing calculator 120.

[0038] In this embodiment, the substrate 110 has a parallelogram shape when viewed from above, and the first direction D1 is horizontal. A portion of the LED light source 112 is adjacent to the first edge E1 of the substrate 110, for example... Figure 1 The topmost LED light source 112. In this document, "part" refers to a portion or some of them, as stated above. The edge of the boundary frame 114 surrounding the LED light source 112 overlaps with the first edge E1 of the substrate 110. In this embodiment, the substrate 110 has a second edge E2 adjacent to the first edge E1, extending along a second direction D2. The first direction D1 and the second direction D2 form an angle θ, and angle θ is an acute angle. In this embodiment, although the first edge E1 also forms an angle θ with the second edge E2, the connection between the first edge E1 and the second edge E2 has a rounded bevel, but the invention is not limited to this. Another portion of the LED light source 112 is adjacent to the second edge E2 of the substrate 110, and overlaps with the second edge E2 of the substrate 110 around the edge of the boundary frame 114 surrounding the LED light source 112. The top view shape of the boundary frame 114 surrounding the LED light source 112 adjacent to the second edge E2 is a right trapezoid, while the remaining boundary frames 114 are rectangular.

[0039] Specifically, when the timing calculator 120 calculates the boundary frame 114, it can set an offset d based on the first direction D1, so that each column of the boundary frame 114 is offset by the offset d in the first direction D1, rather than the traditional boundary frame simply divided by horizontal and vertical lines. This effectively avoids the generation of blank areas (dark areas) without light source at the edges and corners of the irregularly shaped substrate 110, improving light uniformity. Therefore, non-rectangular displays can use this offset d to fine-tune the position of the boundary frame 114, aligning the boundary frame with the light-emitting diode (LED), thus preventing the mismatch between the boundary frame 114 and the LED light source 112. This provides greater flexibility in selecting substrates of different shapes, enhancing product competitiveness. In some embodiments, when the timing calculator 120 calculates the boundary frame 114, it can set the offset based on both the first direction D1 and the second direction D2 simultaneously, but the present invention is not limited to this.

[0040] Figure 2 A schematic diagram illustrating a display panel 100a according to another embodiment of the present invention is shown. (Refer to...) Figure 2 A display panel 100a includes a substrate 110a and a timing calculator 120. The substrate 110a includes a plurality of LED light sources 112. This embodiment is similar to... Figure 1 The implementation differs in that, in this embodiment, the LED light sources 112 are arranged in multiple rows, and these rows are parallel to the first edge E1 of the substrate 110a, which extends along a first direction D1. In this embodiment, the first direction D1 of the substrate 110a is a vertical direction. The substrate 110a has a second edge E2 adjacent to the first edge E1, which extends along a second direction D2 and forms an angle θ with the first edge E1, and the angle θ is an obtuse angle. In some embodiments, the connection between the first edge E1 and the second edge E2 has a rounded chamfer, but the present invention is not limited to this. A portion of the LED light sources 112 is adjacent to the second edge E2 of the substrate 110a, and the edges of the boundary frames 114 surrounding the LED light sources 112 overlap with the second edge E2 of the substrate 110a. Furthermore, the top view shape of the boundary frames 114 surrounding the LED light sources 112 adjacent to the second edge E2 is a right trapezoid, and the remaining boundary frames 114 are rectangular.

[0041] When the timing calculator 120 calculates the boundary frame 114, it can set an offset d based on the first direction D1, so that each row of the boundary frame 114 is offset by the offset d in the first direction D1, instead of the traditional boundary frame simply divided by horizontal and vertical lines. This effectively avoids the generation of blank areas (dark areas) without light source at the edges and corners of the irregularly shaped substrate 110a, and improves light uniformity. Therefore, non-rectangular displays can use this offset d to fine-tune the position of the boundary frame 114, aligning the boundary frame with the light-emitting diode (LED), thus preventing the phenomenon of mismatch between the boundary frame 114 and the LED light source 112.

[0042] Figure 3 A schematic diagram illustrating a display panel 100b according to another embodiment of the present invention is shown. (Refer to...) Figure 3 The display panel 100b includes a substrate 110b and a timing calculator 120. The substrate 110b includes a plurality of LED light sources 112, wherein the LED light sources 112 are arranged in multiple columns, and these columns are parallel to the tangential direction T of the first edge E1 of the substrate 110b. The first edge E1 of the substrate 110b extends along a first direction D1. In this embodiment, the top view shape of the substrate 110b is circular, and the tangential direction T is a horizontal direction parallel to one of the diameters of the substrate 110b. The first direction D1 is the circumferential direction. Boundary frames 114 surround the LED light sources 112, wherein the boundary frames 114 of adjacent columns are offset by an amount d in the tangential direction T. In this embodiment, the edges of the boundary frames 114 are parallel to the tangential direction T. A portion of the LED light source 112 is adjacent to the first edge E1 of the substrate 110b, and one edge of the boundary frame 114 surrounding the LED light source 112 is an arc shape that overlaps with the first edge E1 of the circular substrate 110b.

[0043] Figure 4 A schematic diagram illustrating a display panel 100c according to another embodiment of the present invention is shown. (Refer to...) Figure 4 The display panel 100c includes a substrate 110c and a timing calculator 120. The substrate 110c includes a plurality of LED light sources 112. This embodiment is similar to... Figure 3 The implementation differs in that, in this embodiment, the boundary frame 114 is arranged in concentric circles. The LED light sources 112 are arranged in multiple rings, with the rings parallel to the first edge E1 of the substrate 110c. Figure 4In this embodiment, the boundary frame 114 is depicted as two concentric circles, but this is not intended to limit the invention. For example, more concentric circles of boundary frames 114 may be arranged on the substrate 110c. The first edge E1 of the substrate 110c extends along a first direction D1. The first direction D1 is a circumferential direction. Adjacent concentric circles of boundary frames 114 are offset by an amount d in the first direction D1. Except for the outermost boundary frame 114, in this embodiment, the shape of the boundary frame 114 is trapezoidal or polygonal. One edge of the outermost boundary frame 114 is an arc that overlaps with the first edge E1 of the circular substrate 110c.

[0044] When the timing calculator 120 calculates the boundary frame 114, it can set an offset d based on the first direction D1, so that each ring of the boundary frame 114 is offset by the offset d in the first direction D1, instead of the traditional boundary frame simply divided by horizontal and vertical lines. This effectively avoids the generation of blank areas (dark areas) without light source at the edge of the irregularly shaped substrate 110c, improving light uniformity. Therefore, non-rectangular displays can use this offset d to fine-tune the position of the boundary frame 114, aligning the boundary frame with the light-emitting diode (LED), thus preventing the phenomenon of mismatch between the boundary frame 114 and the LED light source 112.

[0045] Figure 5 A schematic diagram illustrating a display panel 100d according to another embodiment of the present invention is shown. (Refer to...) Figure 5 The display panel 100d includes a substrate 110d and a timing calculator 120. Figure 5 Implementation methods and Figure 1 The difference in implementation lies in that, in this embodiment, the top view shape of the substrate 110d is polygonal. Its shape can be a combination of a trapezoid and a rectangle, but the invention is not limited to this; for example, the substrate 110d can be a pentagon, hexagon, or other polygon. The substrate 110d includes multiple LED light sources 112, which are arranged in multiple columns, parallel to the first edge E1 of the substrate 110d. The first edge E1 can be one of the edges of the polygonal substrate 110d. The timing calculator 120 defines multiple boundary frames 114 around the substrate 110d, and the boundary frames 114 surround the LED light sources 112 respectively. The boundary frames 114 of adjacent columns have an offset d in a first direction D1. In this embodiment, the first direction D1 is horizontal, but the invention is not limited to this.

Those skilled in the art will understand that they can readily use this invention as the basis for designing or modifying other processes and structures to achieve the same objectives and / or advantages as the embodiments described herein.
