The present invention relates to the field of display technology, and in particular, to a display panel, a display device and a manufacturing method thereof.

In recent years, with the development of display technology, people have higher and higher requirements for the functionality and aesthetics of display panels. In order to meet the needs, the design of display panels with irregularly shaped (such as arc-shaped) corner areas has become more and more popular. people's attention.

Displays with curved corner areas have become a trend. Generally, a display screen with an arc-shaped corner area includes an arc-shaped display area and an arc-shaped peripheral area, and the peripheral area is located at the periphery of the display area. In a display device with arc-shaped corner regions, the wiring method of the peripheral driving circuit becomes complicated, and the wiring method also affects the size of the peripheral peripheral area of the display area, thereby affecting the width of the frame of the display device.

3 to 9 are schematic diagrams of a manufacturing process of a display panel according to an embodiment of the present invention.

First, please refer to FIG. 3 . FIG. 3 shows an arc-shaped corner area of the display panel 100 . The display panel 100 (only part of the area is shown in the figure) includes a substrate 110 , and the substrate 110 also has at least one corner area 111 . The corner region 111 is provided with a display region 112 and a peripheral region 113 , wherein the outer edge E of the corner region 111 is in an arc shape, and the arc shape extends along a fixed or variable curvature. In this embodiment, the material of the substrate 110 may be glass, quartz, organic polymers, or opaque/reflective materials (eg, wafers, ceramics, or other applicable materials), or other applicable materials Material. If the substrate 110 chooses to use glass material, the edge E of the corner region 111 may be a glass edge.

In an embodiment of the present invention, the display area 112 also has an outer contour curve AA', and the outer contour curve AA' is the outermost edge curve of the display area 112, which may be substantially parallel to the edge E of the corner area 111. Of course, The present invention is not limited to this. A peripheral area 113 is formed between the outer contour curve AA' of the display area 112 and the edge E of the corner area 111, and the circuit units for arranging the display device are arranged in the peripheral area 113. In this embodiment, the circuit units are arranged in an orderly and compact manner according to certain setting rules, and the area of the peripheral area 113 is reduced, thereby realizing a narrower frame of the display device.

In an embodiment of the present invention, as shown in FIG. 4A , according to the curvature of the edge E of the arc-shaped corner region 111 or the outer contour curve AA′ of the display region 112 , at the edge of the corner region 111 , the edge E Or the outer contour curve AA' as the reference, determine a reference curve M that is roughly parallel to the edge or the outer contour curve AA', and the determination of the specific position of the reference curve M depends on the size and angle of the circuit unit set in the peripheral area 113. The shortest distance between the edge E of the partial area 111 and the outer contour curve AA' of the display area 112. The reference curve M is located between the edge E of the corner area 111 and the outer contour curve AA' of the display area 112.

For example, as shown in FIG. 4B , when the shortest distance D between the edge E of the corner region 111 and the outer contour curve AA′ of the display region 112 is less than ( l +200 μm ) (that is, the The difference between the shortest distance D between the edge E and the outer contour curve AA′ of the display area 112 and the length l of the rectangular circuit unit is less than 200 μm), then the outer contour curve AA′ of the display area 112 is at least 50 μm outward , and make a curve basically parallel to AA' as the reference curve M. At this time, the distance between the outer contour curve AA' and the reference curve M is the first interval D1, then the first interval D1 is greater than or equal to 50 μm , which can guarantee the circuit On the premise that the connection space between the unit and the display area is sufficient, the external space should be increased as much as possible to reduce the space required for the surrounding area.

For another example, as shown in FIG. 4C , when the shortest distance D' between the edge E of the corner area 111 and the outer contour curve AA' of the display area 112 exceeds ( l +200 μm ) (that is, the edge E of the corner area 111 When the difference between the shortest distance D' and the outer contour curve AA' of the display area 112 and the length l of the rectangular circuit unit is greater than 200 μm), it means that the circuit unit already has enough external space, so in the corner area The edge E of 111 is at least ( l +150 μm ) inward, and a curve substantially parallel to the edge E is made as the reference curve M. At this time, the distance between the edge E of the corner area 111 and the reference curve M is the second interval D2 , the second interval D2 is greater than or equal to ( l + 150) μm , which can also increase the connection space between the circuit unit and the display area as much as possible on the premise that the external space is sufficient.

Further, in an embodiment of the present invention, as shown in FIG. 5 , by selecting a plurality of broken line segments to fit the reference curve, the plurality of broken line segments form a broken line, while reducing the number of broken line segments as much as possible, the broken line is kept at the same time. It is a good fit with the reference curve, and optimally, the length of any polyline segment in the polyline is an integer multiple of the width w of the circuit unit, so that the circuit units can be arranged strictly along the position of the polyline segment, so only The distribution of circuit units can be predicted according to the distribution of broken line segments.

In this embodiment, as mentioned above, the side of the circuit unit width w is arranged along the broken line segment, so the length of the broken line segment is an integer multiple of w (1 w , 2 w , 3 w ...... n w ). Further, when using the polyline segment to fit the reference curve, each polyline segment and the corresponding reference curve have a vertical distance d, in order to make the arrangement of the circuit units occupy as small an area as possible and improve space utilization, Therefore, the distance d is not suitable to be too large, for example, the distance d generally does not exceed 50 μm at most.

Specifically, as shown in FIG. 6 , the polyline segment includes, for example, a first polyline segment L1, a second polyline segment L2, and a third polyline segment L3. Of course, the polyline may also include more polyline segments, and this embodiment is for brevity of description. , which is taken as an example, but not as a limitation of the present invention. The first polyline segment L1 shown in the figure has a first length l1 , the second polyline segment L2 has a second length l2 , and the third polyline segment L3 has a third length l3 . The length l 1 , the second length l 2 and the third length l 3 are all integer multiples of the width w of the circuit unit.

The vertical distances between the first polyline segment L1, the second polyline segment L2, and the third polyline segment L3 and the highest point of the reference curve are the first distance d1, the second distance d2, and the third distance d3. In one embodiment, the vertical distance d is also related to the number of circuit units arranged on the broken line segment. For example, the vertical distance d should also be smaller than n*10 μm, where n is the width of the circuit units arranged on the broken line segment with a width of w . number, n is a positive integer. Of course, the upper limit of the vertical spacing d still needs to satisfy the condition that it does not exceed a maximum of 50 μm . Therefore, generally speaking, the first spacing d1≤( l 1/ w )*10 μm, the second spacing d2≤( l 2/ w )*10 μm, and the third spacing d3≤( l 3/ w )*10 μm. From this point of view, it is not appropriate for each polyline segment in the polyline to fit the reference curve to be too long, nor is it appropriate for too many circuit units arranged on any polyline segment.

In an embodiment of the present invention, as shown in FIG. 6 , a plurality of circuit units ER are arranged along the broken line segment. In this embodiment, the circuit units ER are arranged along the broken line segment toward the side away from the display area 112 .

As shown in FIG. 7 , the circuit units ER are arranged in rotation along the first polyline segment L1 , the second polyline segment L2 , and the third polyline segment L3 , and the circuit units ER between adjacent line segments (ie, the turning points) are substantially parallel to the polyline through the The outlines of the line segments are electrically connected, of course, the present invention is not limited to this.

In an embodiment of the present invention, the plurality of circuit units ER include a plurality of first circuit units SR and a plurality of second circuit units TP, the present invention is not limited to this, if necessary, the plurality of circuits The unit may also include a plurality of third circuit units, a plurality of fourth circuit units, etc. For the sake of brevity in the description of the present invention, only a plurality of first circuit units SR and a plurality of second circuit units TP are used as examples, but the present invention does not Not limited to this. The first circuit unit SR is, for example, a shift register circuit unit (SR cell). The circuit unit in this embodiment is shown in FIG. 8 and can be roughly regarded as a rectangular unit with a length of l and a width of w . Inventions are not limited to this. The present invention is not limited to this. As mentioned above, the circuit unit ER is arranged along the line segment of the broken line with its width w . The circuit units ER on the same line segment are arranged compactly with each other, and it is easier to achieve electrical connection with each other, which reduces the manual typesetting of the circuit diagram. The workload is conducive to improving the drawing efficiency and reducing the probability of errors.

In an embodiment of the present invention, the second circuit unit TP is, for example, a touch control unit (TP switch cell), but the present invention is not limited thereto. In this embodiment, as shown in FIG. 9 , the second circuit unit TP and the first circuit unit SR may be alternately arranged. Since the widths of the first circuit unit SR and the second circuit unit TP are different, if the circuit units need to be closely arranged along the broken line segment, the width w 2 of the second circuit unit TP and the width w 1 of the first circuit unit SR are proportional to a certain ratio, so that the circuit unit can be realized. The close arrangement between them avoids unnecessary waste of space and improves space utilization. In this embodiment, for example, w 2 / w 1=2:3, but the present invention is not limited to this.

It should be pointed out that the arc-shaped outer edges of the arc-shaped corner regions 111 in the above-mentioned embodiments selected in this specification are all facing upward (ie, the upper R angle), but the present invention is not limited to this. When the arc-shaped outer edges of the corner regions 111 are all facing downward (ie, the lower R angle), the present invention can also achieve the above-mentioned effects.

In another embodiment of the present invention, a display panel is provided. As shown in FIG. 10 , which is a partial schematic diagram of the display panel according to an embodiment of the present invention, the display panel 200 at least includes a substrate 210 , and the substrate 210 A display area 211 and a peripheral area 212 are disposed thereon, and the substrate has at least one corner area 213 , and an edge E' of the corner area 213 is in an arc shape extending along a curvature. Further, the display area 211 has an outer contour curve aa'. The display panel 200 is also provided with at least one reference curve M', the reference curve M' is set between the edge E' of the corner region 213 and the outer contour curve aa of the display region 211 according to the curvature of the edge E' of the corner region 213 'between. Further, the display panel 200 further includes a plurality of circuit unit groups 220, each circuit unit group 220 is composed of a plurality of circuit units 221, the plurality of circuit unit groups 220 are arranged in parallel around the display area 211, and the plurality of circuit unit groups 220 are arranged side by side. The circuit unit group 220 has an inner side bb′ close to the display area 211 and an outer side cc′ away from the display area 211 .

In an embodiment of the present invention, each circuit unit 221 shown in FIG. 10 can be roughly regarded as a rectangular module with a length l and a width w .

As shown in FIG. 10, the inner side bb' includes at least a first inner side L1', a second inner side L2' and a third inner side L3', wherein the first inner side L1' has a The first length l1 , the second inner side L2' has a second length l2 , and the third inner side L3' has a third length l3 .

In this embodiment, the sides of the plurality of circuit units 221 whose widths are w form the inner sides of the plurality of circuit unit groups 220, and the first length l1 , the second length l2 , and the third length l3 are circuit units 221 Integer multiple of width w .

In an embodiment of the present invention, as shown in FIG. 11 , the reference curve M' is fitted by the above-mentioned inner side bb', and each inner side bb' has a vertical relationship with the corresponding reference curve M' The spacing d' is to make the arrangement of the circuit units occupy as small an area as possible and improve the space utilization rate. Therefore, the spacing d' is not suitable to be too large. For example, the spacing d' generally does not exceed 50 μm at most.

The vertical distances between the first inner side L1', the second inner side L2', and the third inner side L3' respectively and the highest point of the reference curve are the first distance d1', the second distance d2', the third distance d3' (not shown in the figure), in an embodiment of the present invention, the vertical spacing d' is also related to the number of circuit units arranged on the inner side bb', for example, the vertical spacing d' should also be smaller than n *10μm, where n is the number of circuit units with width w arranged on the broken line segment, and n is a positive integer. Of course, the upper limit of the vertical spacing d' still needs to satisfy the condition that it does not exceed a maximum of 50 μm . Therefore, generally speaking, the first spacing d1'≤( l 1/ w )*10μm, the second spacing d2'≤( l 2/ w )*10μm, and the third spacing d3'≤( l 3/ w )*10μm. From this point of view, it is not suitable for each inner side bb' of the fitting reference curve to be too long, and it is not suitable for too many circuit units arranged on any inner side bb'.

In an embodiment of the present invention, there is a first interval D1' between the reference curve M' and the outer contour curve aa' of the display area 211, which is increased as much as possible under the premise that the connection space between the circuit unit and the display area is sufficient. For the external space, the first interval D1 ′ can be, for example, 50 μm, and at the same time, in order to save the space of the peripheral area 212 and achieve higher space utilization, the first interval D1 ′ can be appropriately smaller than 50 μm. In this case, the inner side bb′ of the circuit unit group 220 is close to the display area 211 , and the outer side cc′ is relatively far away from the display area 211 . Further, when the first interval D1 ′ between the reference curve M′ and the outer contour curve aa′ of the display area 211 does not exceed 50 μm, the distance between the outer contour curve aa′ of the display area 211 and the edge of the corner area 213 is not more than 50 μm. The shortest pitch is less than ( l + 200) μm. Otherwise, if the shortest distance between the outer contour curve aa' of the display area 211 and the edge of the corner area 213 exceeds ( l +200) μm, in another embodiment of the present invention, the reference curve M' and the corner area There is a second interval D2' between the edges of the 213. Since the inner side bb' of the circuit unit group 220 is required to fit the reference curve M', a sufficient space needs to be reserved between the reference curve and the edge of the corner region 213. The circuit unit group 210 is arranged, and the connection space between the circuit unit and the display area is increased as much as possible on the premise of ensuring sufficient external space. The second interval D2' can be, for example, ( l +150) μm.

In an embodiment of the present invention, the plurality of circuit units 221 may at least include a plurality of first circuit units SR and a plurality of second circuit units TP, and if necessary, the plurality of circuit units may further include a plurality of third circuit units The circuit unit, the plurality of fourth circuit units, etc., for the sake of brevity in the description of the present invention, only the plurality of first circuit units SR and the plurality of second circuit units TP are taken as examples, but the present invention is not limited thereto. The first circuit unit SR may be, for example, a shift register circuit unit (SR cell), and the second circuit unit TP may be, for example, a touch control circuit unit (TP switch cell).

In the embodiment of the present invention, the second circuit unit TP and the first circuit unit SR are alternately arranged, that is, the first circuit unit SR and the second circuit unit TP are co-parallel, and the inner parts of the first circuit unit SR and the second circuit unit TP are The sides are connected together to form the inner side bb' of the circuit unit group 220. In order to ensure the effective use of space and realize the close arrangement between the circuit units, it is necessary to maintain the length of the inner side bb' to be an integer of the width w of the circuit unit 221. times, it is first necessary to ensure that the widths of the first circuit unit SR and the width of the second circuit unit TP are in a corresponding proportional relationship. In an embodiment of the present invention, the ratio of the width w 1 of the first circuit unit SR to the width w 2 of the second circuit unit TP may be, for example, w 2 / w 1 =2:3.
