Description
Technical Field
The invention relates to the technical field of display, in particular to a display panel, a display device and a manufacturing method thereof.
Background
In recent years, with the development of display technology, the demand for functionality and aesthetic appearance of display panels has become higher, and in order to meet the demand, the design of display panels having irregular (e.g., arc-shaped) corner regions has been receiving more and more attention.
There has been a trend towards display screens having curved corner regions. Generally, a display panel having an arc-shaped corner region includes an arc-shaped display region and an arc-shaped peripheral region, and the peripheral region is located at the periphery of the display region. In the display device having the arc-shaped corner region, the wiring pattern of the peripheral driving circuit becomes complicated, and the wiring pattern also affects the size of the peripheral region area around the display region, and further affects the width of the frame of the display device.
In the display device having the arc-shaped corner region in the prior art, the registers of the driving circuit generally have two arrangement layouts, one is to arrange the registers in the arc-shaped corner region in segments along the vertical and horizontal directions at the outer edge of the corner region of the display region, with at least two stages of registers as units; the other is that the registers are rotationally arranged along the outer edge of the corner area in the belly of the arc-shaped corner area, the directions of the registers are radial, and the registers at each stage can be closely arranged or dispersedly arranged according to the corresponding pixel positions. As shown in fig. 1, the register units are arranged on the outer edge of the corner region of the display region along the vertical and horizontal directions in a segmented manner on the web of the arc-shaped corner region, the registers occupy a large space on the web of the arc-shaped corner region, and the register units cannot be tightly arranged due to the turning of the bus (bus line), so that certain space waste exists, and the narrower frame is not favorably realized. Meanwhile, connecting wires between the registers need to be connected manually, so that the workload is large, the error rate is high, and staggered arrangement between a touch control unit (TP switch) and the register units cannot be realized; the number of register stages provided in the arc-shaped corner region is small, and fan-out (fan out) routing is required in the straight region, so that it is difficult to realize a narrower frame.
Another is that as shown in fig. 2, the arc-shaped corner regions are arranged along the outer edges of the corner regions in a rotating manner, and in the layout mode, the arc-shaped bus (bus line) cannot be precisely matched with the TFT devices in the register, and manual trimming is required; the register unit has more segments, and manual connection among the segments is also more; registers at different angles are all different units, and later adjustment and modification are difficult; the touch control unit (TP switch) is difficult to be matched with the arc-shaped bus (bus line) when arranged in the arc-shaped corner area.
Therefore, how to design a narrow frame of a display panel and better consider layout rationality, save space and reduce connection error rate is a technical problem to be solved urgently by technical personnel in the field.

Detailed Description
The invention will be described in detail with reference to the following drawings, which are provided for illustration purposes and the like:
as used herein, "about," "approximately," "essentially," or "substantially" includes the average of the stated value and a specified value within an acceptable range of deviation from the stated value, as determined by one of ordinary skill in the art, given the particular number of measurements in question and the errors associated with the measurements (i.e., the limitations of the measurement system). For example, "about" can mean within one or more standard deviations of the stated values, or, for example, ± 30%, ± 20%, ± 15%, ± 10%, ± 5%. Further, as used herein, "about", "approximately", "essentially", or "substantially" may be selected based on the measured property, cleavage property, or other property to select a more acceptable range of deviation or standard deviation, and not one standard deviation may apply to all properties.
In the drawings, the thickness of layers, films, panels, regions, etc. have been exaggerated for clarity. It will be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected" to another element, there are no intervening elements present. As used herein, "connected" may refer to physical and/or electrical connections. Furthermore, an "electrical connection" may be the presence of other elements between the two elements.
Furthermore, relative terms such as "lower" or "bottom" and "upper" or "top" may be used herein to describe one element's relationship to another element, as illustrated. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. Thus, the exemplary term "lower" can include both an orientation of "lower" and "upper," depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" or "beneath" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "above" or "below" may include both an orientation of above and below.
Reference will now be made in detail to exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the description to refer to the same or like parts.
Fig. 3-9 are schematic diagrams illustrating a manufacturing process of a display panel according to an embodiment of the invention.
Referring to fig. 3, fig. 3 is an arc-shaped corner region of the display panel 100, the display panel 100 (only a partial region is shown in the figure) includes a substrate 110, the substrate 110 further has at least one corner region 111, a display region 112 and a peripheral region 113 are disposed in the corner region 111, wherein an outer edge E of the corner region 111 is in an arc shape, and the arc shape extends along a constant curvature or a variable curvature. In the present embodiment, the substrate 110 may be made of glass, quartz, organic polymer, or opaque/reflective material (e.g., wafer, ceramic, or other suitable material), or other suitable material. If the substrate 110 is made of glass, the edge E of the corner region 111 may be a glass edge line.
In an embodiment of the present invention, the display area 112 further has an outer contour curve AA', which is an outermost edge curve of the display area 112 and may be substantially parallel to the edge E of the corner area 111, although the invention is not limited thereto. 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 circuit units of the display device are arranged in the peripheral area 113. In the embodiment, the circuit units are orderly and compactly arranged according to a certain setting rule, and the area of the peripheral region 113 is reduced, so that a narrower frame of the display device is realized.
In an embodiment of the 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, a reference curve M substantially parallel to the edge or the outer contour curve AA' is determined at the edge of the corner region 111 based on the edge E or the outer contour curve AA ', and the specific position of the reference curve M is determined according to the size of the circuit unit disposed in the peripheral region 113 and the shortest distance between the edge E of the corner region 111 and the outer contour curve AA' of the display region 112. The reference curve M is located between the edge E of the corner region 111 and the outer contour curve AA' of the display region 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 smaller than (l +200 μ M) (i.e. the difference between the shortest distance D between the edge E of the corner region 111 and the outer contour curve AA ' of the display region 112 and the length l of the rectangular circuit unit is smaller than 200 μ M), a curve substantially parallel to the outer contour curve AA ' is made as the reference curve M when the outer contour curve AA ' of the display region 112 faces outward by at least 50 μ M, and the distance between the outer contour curve AA ' and the reference curve M is the first distance D1, and the first distance D1 is greater than or equal to 50 μ M, so as to increase the external space as much as possible on the premise of ensuring sufficient connection space between the circuit unit and the display region, so as to reduce the space area required by the peripheral region.
For another example, as shown in fig. 4C, 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 exceeds (l +200 μ M) (i.e. the difference between the shortest distance D 'between the edge E of the corner region 111 and the outer contour curve AA' of the display region 112 and the length l of the rectangular circuit unit is greater than 200 μ M), it is indicated that the circuit unit already has enough external space, so that a curve substantially parallel to the edge E is made as the reference curve M when the edge E of the corner region 111 is inward at least (l +150 μ M), and the distance between the edge E of the corner region 111 and the reference curve M is the second distance D2, and the second distance D2 is greater than or equal to (l +150) μ M, so as to increase the connection space between the circuit unit and the display region as much as possible under the premise of ensuring enough external space.
Further, in an embodiment of the present invention, as shown in fig. 5, a plurality of broken line segments are selected to fit a reference curve, and the plurality of broken line segments form a broken line, so that the number of broken line segments is reduced as much as possible, and the broken line keeps a better fit with the reference curve, and optimally, the length of any broken line segment in the broken line is an integral multiple of the width w of the circuit unit, so that the circuit units can be strictly arranged along the positions of the broken line segments, and therefore, the distribution of the circuit units can be predicted only according to the distribution of the broken line segments.
In the present embodiment, as described above, the side where the width of the circuit cell is w is arranged along the broken line segment, and therefore the length of the broken line segment is an integral multiple of w (1w,2w,3w … … nw). Further, when the reference curve is fitted with the polygonal line segments, a vertical distance d is formed between each polygonal line segment and the corresponding reference curve, so that the layout of the circuit units occupies a minimum area and space utilization is improved, and therefore the distance d is not suitable to be too large, for example, the maximum distance d is generally not more than 50 μm.
Specifically, as shown in fig. 6, the polyline segments include, for example, a first polyline segment L1, a second polyline segment L2, and a third polyline segment L3, but the present embodiment is for convenience of explanation and is not intended to limit the present invention. The first broken line segment L1 is shown to have a first length L1, the second broken line segment L2 has a second length L2, and the third broken line segment L3 has a third length L3, and preferably, the first length L1, the second length L2, and the third length L3 are all integer multiples of the circuit cell width w.
The vertical distances between the first broken line segment L1, the second broken line segment L2, and the third broken line segment L3 and the highest point of the reference curve are a first distance d1, a second distance d2, and a third distance d3, in an embodiment of the present invention, the vertical distance d is further related to the number of circuit units arranged on the broken line segment, for example, the vertical distance d should be smaller than n 10 μm, where n is the number of circuit units arranged on the selected broken line segment and having a width of w, and n is a positive integer. Of course, the upper limit of the vertical spacing d is also required to satisfy the condition of not exceeding 50 μm at maximum. Thus, in general, the first spacing d1 is no more than (l1/w) 10 μm, the second spacing d2 is no more than (l2/w) 10 μm, and the third spacing d3 is no more than (l3/w) 10 μm. From this point of view, each broken line segment in the broken lines fitting the reference curve is not suitable to be too long, and the circuit units arranged on any broken line segment are not suitable to be too many.
In an embodiment of the present invention, as shown in fig. 6, the plurality of circuit units ER are arranged along the broken line segment, and in this embodiment, the circuit units ER are arranged along the broken line segment toward the side far away from the display area 112.
As shown in fig. 7, the circuit cells ER are rotationally arranged along the first, second and third broken line segments L1, L2 and L3, and the circuit cells ER between adjacent segments (i.e. at the turning points) are electrically connected by an outline substantially parallel to the broken line segments, although the invention is not limited thereto.
In an embodiment of the invention, the plurality of circuit units ER includes a plurality of first circuit units SR and a plurality of second circuit units TP, and the invention is not limited thereto, and if necessary, the plurality of circuit units may further include a plurality of third circuit units, a plurality of fourth circuit units, and the like. The first circuit unit SR is, for example, a shift register circuit unit (SR cell), and the circuit unit in the embodiment can be regarded as a rectangular unit with a length of l and a width of w as shown in fig. 8, which is not limited to the disclosure. The invention is not limited thereto. As mentioned above, the circuit units ER are arranged along the broken line segment on the side with the width of w, and the circuit units ER on the same line segment are mutually compactly arranged, so that the circuit units ER are easily electrically connected with each other, the manual typesetting workload of the circuit diagram is reduced, the drawing efficiency is improved, and the error probability is reduced.
In an embodiment of the invention, the second circuit unit TP is, for example, a touch control unit (TP switch cell), and the invention is not limited thereto. In the present embodiment, as shown in fig. 9, the second circuit units TP and the first circuit units SR may be alternately arranged. Because the widths of the first circuit unit SR and the second circuit unit TP are different, if the first circuit unit SR and the second circuit unit TP are closely arranged along a broken line segment, the width w2 of the second circuit unit TP is in a certain proportion to the width w1 of the first circuit unit SR, so that the circuit units can be closely arranged, unnecessary space waste is avoided, and the space utilization rate is improved. In this embodiment, for example, w2/w1 is 2:3, but the invention is not limited thereto.
It should be noted that the arc-shaped outer edge of the arc-shaped corner region 111 in the above embodiments selected in the present specification faces upward (i.e., the upper R corner), but the present invention is not limited thereto, and the above effects can be achieved when the arc-shaped outer edge of the arc-shaped corner region 111 faces downward (i.e., the lower R corner).
In another embodiment of the present invention, as shown in fig. 10, fig. 10 is a partial schematic view of a display panel according to an embodiment of the present invention, the display panel 200 at least includes a substrate 210, the substrate 210 is provided with a display area 211 and a peripheral area 212, 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'. At least one reference curve M ' is further disposed on the display panel 200, and the reference curve M ' is disposed 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. Further, the display panel 200 further includes a plurality of circuit unit sets 220, each circuit unit set 220 is composed of a plurality of circuit units 221, the plurality of circuit unit sets 220 are arranged in parallel around the display region 211, and the plurality of circuit unit sets 220 have an inner side bb 'close to the display region 211 and an outer side cc' far away from the display region 211.
In one 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 edge bb ' comprises at least a first inner side edge L1 ', a second inner side edge L2 ', and a third inner side edge L3 ', wherein the first inner side edge L1 ' has a first length L1, the second inner side edge L2 ' has a second length L2, and the third inner side edge L3 ' has a third length L3.
In the present embodiment, the plurality of circuit cells 221 form the inner side edges of the plurality of circuit cell groups 220 with the sides having the width w, and the first length l1, the second length l2, and the third length l3 are integer multiples of the width w of the circuit cells 221.
In an embodiment of the present invention, as shown in fig. 11, the reference curves M ' are fitted through the inner side edges bb ', and a vertical distance d ' is provided between each inner side edge bb ' and the corresponding reference curve M ', so that the arrangement of the circuit units occupies a minimum area, and the space utilization is improved, and therefore the distance d ' is not suitable to be too large, for example, the distance d ' is usually not more than 50 μ M at most.
In an embodiment of the present invention, the vertical distances between the first inner side edge L1 ', the second inner side edge L2 ', and the third inner side edge L3 ' and the highest point of the reference curve are a first distance d1 ', a second distance d2 ', and a third distance d3 ' (not shown in the drawings), for example, the vertical distance d ' is further smaller than n 10 μm, where n is the number of the circuit units arranged on the selected segment of the broken line and has a width w, and n is a positive integer. Of course, the upper limit of the vertical spacing d' is also required to satisfy the condition of not exceeding 50 μm at the maximum. Thus, in general, the first spacing d1 ' is no more than (l1/w) 10 μm, the second spacing d2 ' is no more than (l2/w) 10 μm, and the third spacing d3 ' is no more than (l3/w) 10 μm. From this viewpoint, the inner side edges bb 'of the fitting reference curve are not necessarily too long, and the circuit units arranged in any one of the inner side edges bb' are not necessarily too many.

In this case, the inner side bb 'of the circuit unit group 220 is close to the display region 211, and the outer side cc' is relatively far from the display region 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 μ M, the shortest distance between the outer contour curve aa' of the display area 211 and the edge of the corner area 213 is less than (l +200) μ M. Otherwise, if the shortest distance between the outer contour curve aa 'of the display region 211 and the edge of the corner region 213 exceeds (l +200) μ M, in another embodiment of the present invention, there is a second interval D2' between the reference curve M 'and the edge of the corner region 213, since the inner side bb' of the circuit unit group 220 is needed to fit the reference curve M ', it is necessary to leave a sufficient space between the reference curve and the edge of the corner region 213 to set the circuit unit group 210, and at the same time, to increase the connection space between the circuit unit and the display region as much as possible on the premise of ensuring sufficient external space, and the second interval D2' may be (l +150) μ M, for example.
In an embodiment of the invention, the plurality of circuit units 221 may include at least 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, a plurality of fourth circuit units, and the like. 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).
