Description

Display panel and display device Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device. Background Art

[0002] OLED (Organic Light-Emitting Diode) displays are widely used in various fields due to their lightweight, wide viewing angle, fast response, low-temperature resistance, high luminous efficiency, and the ability to create flexible, curved displays. To implement fingerprint recognition, OLED displays often incorporate a fingerprint module. Specifically, fingerprint technologies are categorized into capacitive, optical, and ultrasonic technologies. Optical fingerprints include under-display and in-display. With the trend toward thinner and lighter displays, in-display optical fingerprint technology has become a preferred option for OLED displays. In-display optical fingerprint technology integrates an optical fingerprint sensor within the display. This technology uses infrared light to illuminate a finger and reflect it back. The optical fingerprint sensor then receives the reflected light and extracts fingerprint features, thereby enabling fingerprint recognition. Furthermore, OLED displays incorporate touch traces to implement touch control. These traces can reflect some of the light emitted by the pixel cells toward the optical fingerprint sensor, causing interference, lowering the signal-to-noise ratio, and degrading performance.

[0003] Therefore, existing OLED display devices have a technical problem in which the touch lines reflect the light emitted by the pixel units, resulting in a low signal-to-noise ratio of the optical fingerprint sensor. SUMMARY OF THE INVENTION

[0033] As shown in FIG1 , conventional display devices implement fingerprint recognition and touch functions by respectively providing an optical fingerprint sensor 12 and touch lines 13 within the screen. Specifically, the display device includes a blue sub-pixel 111, a red sub-pixel 112, and a green sub-pixel 113. The touch lines 13 surround each green sub-pixel 113, and portions of the touch lines 13 are connected to each other. The optical fingerprint sensor 12 is longitudinally disposed between adjacent green sub-pixels 113. As shown in FIG2 , which is a schematic cross-sectional view taken along line A1-A2 in FIG1 , the display device includes a pixel definition layer 121, green sub-pixels 113, an optical fingerprint sensor 12, an encapsulation layer 122, an insulating layer 123, touch lines 13, and a planarization layer 124. The green sub-pixels 113 and optical fingerprint sensor 12 are shown for illustrative purposes only, and their specific structures are not shown. FIG2 illustrates that when the green sub-pixels 113 on either side of the optical fingerprint sensor 12 emit light, light 125 is reflected by the touch lines 13 and reaches the optical fingerprint sensor 12. The optical fingerprint sensor 12 works by receiving light reflected from the finger for fingerprint recognition. Therefore, the optical fingerprint sensor 12 is subject to interference from light reflected from the touch lines 13, resulting in a reduced signal-to-noise ratio (SNR) and poor performance. Therefore, existing OLED display devices suffer from the technical problem of a low SNR in the optical fingerprint sensor due to light reflected from pixel units by the touch lines.

[0034] In response to the above technical problems, embodiments of the present application provide a display panel and a display device to improve the above technical problems.

[0035] As shown in FIG3 and FIG4 , an embodiment of the present application provides a display panel. The display panel 1 includes:

[0036] substrate 41;

[0037] A driving circuit layer 42 , which is disposed on one side of the substrate 41 , and includes a plurality of driving circuits 421 and optical sensors 22 disposed between the driving circuits 421 ;

[0038] The light-emitting layer 43 is provided on a side of the driving circuit layer 42 away from the substrate 41 . The light-emitting layer 43 includes: a plurality of pixel units 21 arranged in an array, and the pixel units 21 are electrically connected to the corresponding driving circuits 421 ;

[0039] A touch layer 32 is provided on a side of the light-emitting layer 43 away from the substrate 41 . The touch layer 32 includes a plurality of touch electrodes 44 . The touch electrodes 44 include touch patterns 23 provided between the pixel units 21 .

[0040] Among them, the multiple pixel units 21 include: a first sub-pixel unit 211, a second sub-pixel unit 212 and a third sub-pixel unit 213, the multiple first sub-pixel units 211 and the multiple second sub-pixel units 212 are alternately arranged in the first direction 241 to form a plurality of first pixel rows 511, the multiple first sub-pixel units 211 and the multiple second sub-pixel units 212 are alternately arranged in the second direction 242 to form a plurality of first pixel columns 521, the multiple third sub-pixel units 213 are arranged in the first direction 241 to form a plurality of second pixel rows 512, and the multiple third sub-pixel units 213 are arranged in the second direction 242 to form a plurality of second pixel columns 522, and the first direction 241 intersects with the second direction 242; in actual application, the first pixel rows 511 and the second pixel rows 512 can be alternately arranged in the second direction 242; the first pixel columns 521 and the second pixel columns 522 can be alternately arranged in the first direction 241.

[0041] The optical sensor 22 is disposed between the adjacent first sub-pixel units 211 and the second sub-pixel units 212 in the first direction 241 , and the optical sensor 22 is disposed between the adjacent third sub-pixel units 213 in the second direction 242 ;

[0042] In the first direction 241 , the touch pattern 23 is not provided between the optical sensor 22 and at least one of the adjacent first sub-pixel unit 211 and the second sub-pixel unit 212 ;

[0043] In the second direction 242 , the touch pattern 23 is not disposed between the optical sensor 22 and at least one of the adjacent third sub-pixel units 213 .

[0044] An embodiment of the present application provides a display panel, which does not provide a touch pattern between the optical sensor and at least one of the adjacent third sub-pixel units. Therefore, when the third sub-pixel unit emits light, the light reflected from the touch electrode to the optical sensor is reduced, the interference of the light from the pixel unit reflected by the touch electrode on the optical sensor is reduced, and the signal-to-noise ratio of the optical sensor is improved.

[0045] Specifically, as shown in FIG3 , the touch pattern 23 includes a first line segment 231 surrounding the third sub-pixel unit 213 and a second line segment 232 connecting the first line segment 231. Within the region corresponding to the third sub-pixel unit 213 and the optical sensor 22, at least one of the first line segments 231 surrounding the third sub-pixel unit 213 has its two ends disconnected, forming a break 25. By disconnecting the two ends of the first line segment surrounding the touch unit of the third sub-pixel unit to form a break, and by positioning the break in the region opposite the optical sensor and the third sub-pixel unit, when the third sub-pixel unit emits light, the presence of the break reduces the amount of light reflected from the touch unit to the optical sensor, thereby reducing interference of the light reflected from the touch unit on the optical sensor and improving the signal-to-noise ratio of the optical sensor.

[0046] Specifically, the touch pattern refers to the pattern of an electrode in the touch layer. In actual products, it can be an electrode or line composed of multiple line segments. The touch pattern, touch electrode, and touch line are only different in name. They are all conductive lines or conductive blocks that function as touch sensors. The electrode can be a touch electrode or a sensing electrode. The design of the touch pattern varies depending on the design of the touch layer, and this is not limited in the embodiments of the present application. Similarly, the design of the touch layer is not limited in the embodiments of the present application. The electrodes in the touch layer in the embodiments of the present application can be of self-capacitive design or mutual-capacitive design. The touch layer in the embodiments of the present application can include only one conductive film layer where the touch pattern is located, or it can include two conductive film layers: the film layer where the touch pattern is located and a bridging layer. This is not limited in the embodiments of the present application.

[0047] Specifically, based on the design of different touch layers, the local design schematic of the display area of ​​the display panel provided in the embodiment of the present application may be the same as or different from the overall design of the display area of ​​the display panel. For example, when the touch layer only includes one conductive layer, the local design of the display area of ​​the display panel provided in the embodiment of the present application is the same as the overall design of the display area, and only the connection lines connected to the touch chip are not shown. For example, when the touch layer includes two conductive layers, the embodiment of the present application only shows the design of the touch pattern at a single touch electrode, and the embodiment of the present application does not limit the design of the other electrode and the bridge. It can be understood that the touch electrode includes a driving electrode and a sensing electrode, and both the driving electrode and the sensing electrode can adopt the design described in the above embodiment. One of the driving electrode and the sensing electrode is provided on the entire surface, and the other is connected at the connection of the two electrodes through a bridge layer.

[0048] Specifically, in the drawings in the embodiments of the present application, the angle A between the first direction 241 and the second direction 242 is 90 degrees for illustration, but the embodiments of the present application are not limited thereto, and the angle between the first direction 241 and the second direction 242 may be an acute angle.

[0049] Specifically, the first direction may be horizontal, and the second direction may be vertical, or the first direction may be vertical, and the second direction may be horizontal.

[0050] Specifically, as shown in Figures 3 and 4, it can be seen that the first line segment 231 surrounding the third sub-pixel unit 213 has a break 25 on the lower side, and there is no line segment between the third sub-pixel unit 213 and the optical sensor 22 on the lower side, so that when the third sub-pixel unit 213 emits light, the light emitted by the third sub-pixel unit 213 on the optical sensor 22 will not be reflected by the touch wiring, thereby reducing the light 316 reflected by the touch wiring to the optical sensor 22, reducing the interference of the light of the pixel unit reflected by the touch wiring on the optical sensor, and improving the signal-to-noise ratio of the optical sensor.

[0051] Specifically, as shown in FIG. 1 and FIG. 3 , it can be seen that the embodiment of the present application removes part of the touch pattern, but the various parts of the touch pattern are still connected together, and there is no problem of disconnection causing the electrical signal to be unable to be transmitted.

[0052] Specifically, as shown in FIG4 , one of the two third sub-pixel units 213 located on either side of the optical sensor 22 has a line segment with the touch pattern 23 between it and the optical sensor 22, so that light emitted by this third sub-pixel unit 213 is reflected toward the optical sensor 22. The other third sub-pixel unit 213 has a line segment with no touch pattern 23 between it and the optical sensor 22, so that light emitted by this third sub-pixel unit 213 is not reflected toward the optical sensor 22. This reduces the amount of light reflected from the touch pattern 23 toward the optical sensor 22 and improves the signal-to-noise ratio of the optical sensor. In some embodiments, a first line segment surrounding the third sub-pixel unit is provided with a break.

[0053] In some embodiments, in one of the touch electrodes, in one of the second pixel columns, the touch pattern is not set between the optical sensor and the adjacent third sub-pixel unit on its first side; in an adjacent second pixel column, the touch pattern is also not set between the optical sensor and the adjacent third sub-pixel unit on its first side.

[0054] In some embodiments, in one of the touch electrodes, in one of the second pixel columns, the touch pattern is not set between the optical sensor and the adjacent third sub-pixel unit on its first side; in an adjacent second pixel column, the touch pattern is not set between the optical sensor and the adjacent third sub-pixel unit on its second side, and the first side is opposite to the second side.

[0055] In some embodiments, the area of ​​the first sub-pixel unit is greater than the area of ​​the second sub-pixel unit.

[0056] In the first pixel row, the touch pattern is not arranged between the optical sensor and the first sub-pixel unit adjacent thereto, and the touch pattern is arranged between the optical sensor and the second sub-pixel unit adjacent thereto.

[0057] In some embodiments, the area of ​​the first sub-pixel unit is greater than the area of ​​the second sub-pixel unit.

[0058] In the first pixel row, the touch pattern is not arranged between the optical sensor and the adjacent second sub-pixel unit, and the touch pattern is arranged between the optical sensor and the adjacent first sub-pixel unit.

[0059] In some embodiments, the area of ​​the first sub-pixel unit is larger than the area of ​​the second sub-pixel unit.

[0060] In one of the first pixel columns, the touch pattern is not set between the optical sensor and the adjacent first sub-pixel unit, and the touch pattern is not set between the optical sensor and the adjacent second sub-pixel unit; in an adjacent second pixel column, the touch pattern is set between the optical sensor and the adjacent first sub-pixel unit, and the touch pattern is set between the optical sensor and the adjacent second sub-pixel unit.

[0061] In some embodiments, in one of the first pixel columns, the touch pattern is disposed between the first sub-pixel unit and the second sub-pixel unit.

[0062] In some embodiments, the touch pattern includes a first line segment arranged around the third sub-pixel unit and a second line segment connecting the first line segment. In the area corresponding to the third sub-pixel unit and the optical sensor, both ends of at least one of the first line segments surrounding the third sub-pixel unit are disconnected and form a break.

[0063] In some embodiments, the first end of the first line segment is connected to one end of one of the second line segments, and the second end of the first line segment is connected to one end of another of the second line segments.

[0064] In some embodiments, the first end of the first line segment is connected to one end of the second line segment, one end of another second line segment is connected to a first point on the first line segment, and the width of the portion from the first point on the first line segment to the second end of the first line segment is greater than 0.

[0065] In some embodiments, one second line segment is connected to the second point on the first line segment, another second line segment is connected to the third point on the first line segment, and the width of the portion between the second point on the first line segment and either end of the first line segment is greater than 0, and the width of the portion between the third point on the first line segment and either end of the first line segment is greater than 0.

[0066] A single break in a first line segment surrounding a third sub-pixel unit can result in a significant amount of light being reflected onto the optical sensor. In some embodiments, as shown in FIG3 , a plurality of first line segments 231 surrounding the third sub-pixel unit 213 are each provided with a break 25 in the region between the third sub-pixel unit 213 and the optical sensor 22. By providing breaks in the region between the third sub-pixel unit and the optical sensor, light reflected from the touch pattern onto the optical sensor can be further reduced, further improving the signal-to-noise ratio of the optical sensor.

[0067] Specifically, the multiple first line segments surrounding the third sub-pixel unit include two first line segments surrounding the third sub-pixel unit and three first line segments surrounding the third sub-pixel unit, but the embodiments of the present application are not limited thereto, and the multiple can be any value greater than or equal to two.

[0068] In some embodiments, as shown in FIG3 , in the region corresponding to the third sub-pixel unit 213 and the optical sensor 22, the plurality of cutouts 25 are located on the same side of the plurality of third sub-pixel units 213. By locating the plurality of cutouts on the same side of the plurality of third sub-pixel units, the reflected light of the touch pattern received by each optical sensor comes from the same side. This facilitates processing of the reflected light of the touch pattern in subsequent processing, thereby reducing interference of the light from the pixel unit reflected by the touch pattern on the optical sensor and improving the signal-to-noise ratio of the optical sensor.

[0069] Specifically, as shown in FIG. 3 , all the breaks 25 may be located on the same side of all the third sub-pixel units 213 .

[0070] In some embodiments, as shown in Figures 3 and 5 , in one of the touch electrodes 44, in one of the second pixel columns 522, no touch pattern 23 is disposed between the optical sensor 22 and the adjacent third sub-pixel unit 213 on its first side (the lower side in Figure 3 ). In an adjacent second pixel column 522, no touch pattern 23 is disposed between the optical sensor 22 and the adjacent third sub-pixel unit 213 on its first side (the lower side in Figure 3 ). By aligning the sides of the optical sensors and the adjacent third sub-pixel units where no touch pattern is disposed, the reflected light of the touch pattern received by each optical sensor comes from the same side. This facilitates processing of the reflected light of the touch pattern in subsequent processing, reduces interference of the light from the pixel units reflected by the touch pattern on the optical sensor, and improves the signal-to-noise ratio of the optical sensor.

[0071] Specifically, the first side may be the upper side, or the first side may be the lower side.

[0072] Specifically, as shown in FIG3 , in each second pixel column 522 , the touch pattern 23 is not disposed between the optical sensor 22 and the adjacent third sub-pixel unit 213 below it.

[0073] Specifically, as shown in FIG. 5 , in each second pixel column 522 , the touch pattern 23 is not disposed between the optical sensor 22 and the upper adjacent third sub-pixel unit 213 .

[0074] In some embodiments, as shown in FIG5 , in the second direction 242, the break 25 is provided between the third sub-pixel unit 213 and the optical sensor 22 located in a row above the third sub-pixel unit 213. By locating the break between the third sub-pixel unit and the optical sensor located in a row above the third sub-pixel unit, reflection of light from the touch pattern on the third sub-pixel unit below the optical sensor can be reduced, and interference of light from the pixel unit reflected by the first line segment of the touch pattern on the optical sensor can be reduced, thereby improving the signal-to-noise ratio of the optical sensor.

[0075] Specifically, all the breaks 25 may be located between the third sub-pixel unit 213 and the optical sensor 22 located in an upper row of the third sub-pixel unit 213 .

[0076] In some embodiments, as shown in FIG3 , in the second direction 242, the break 25 is provided between the third sub-pixel unit 213 and the optical sensor 22 located in the row below the third sub-pixel unit 213. By locating the break between the third sub-pixel unit and the optical sensor located in the row below the third sub-pixel unit, reflection of light from the third sub-pixel unit on the optical sensor by the touch pattern can be reduced, and interference of light from the pixel unit reflected by the first line segment of the touch pattern on the optical sensor can be reduced, thereby improving the signal-to-noise ratio of the optical sensor.

[0077] Specifically, all the breaks 25 may be located between the third sub-pixel unit 213 and the optical sensor 22 located in a row below the third sub-pixel unit 213 .

[0078] In some embodiments, as shown in FIG11 , in one of the touch electrodes 44, in one of the second pixel columns 522, no touch pattern 23 is disposed between the optical sensor 22 and the adjacent third sub-pixel unit 213 on its first side (e.g., the upper side). In an adjacent second pixel column 522, no touch pattern 23 is disposed between the optical sensor 22 and the adjacent third sub-pixel unit 213 on its second side (e.g., the lower side), where the first side is opposite to the second side. By eliminating the touch pattern between the optical sensor and third sub-pixel units in different directions, reflection of light from the touch pattern on third sub-pixel units in different directions of the optical sensor can be reduced, thereby reducing interference of light from pixel units reflected by the touch pattern on the optical sensor and improving the signal-to-noise ratio of the optical sensor.

[0079] Specifically, as shown in Figure 11, it can be seen that in the first column of the second pixel column 522, the touch pattern 23 is not set between the optical sensor 22 and the adjacent third sub-pixel unit 213 on its lower side, and in the second column of the second pixel column 522, the touch pattern 23 is not set between the optical sensor 22 and the adjacent third sub-pixel unit 213 on its upper side.

[0080] In some embodiments, as shown in FIG6 , in the region corresponding to the third sub-pixel unit 213 and the optical sensor 22, the plurality of breaks 25 are located on different sides of the plurality of third sub-pixel units 213. By arranging the breaks on different sides of the third sub-pixel units, the reflection of light from the touch pattern on the third sub-pixel units in different directions on the optical sensor can be reduced, thereby reducing interference of light from the pixel unit reflected by the touch pattern on the optical sensor and improving the signal-to-noise ratio of the optical sensor.

[0081] Specifically, as shown in Figure 6, in the second direction 242, it can be seen that part of the break 25 is opened on the upper side of the third sub-pixel unit 213, that is, part of the break 25 is opened between the third sub-pixel unit 213 and the optical sensor 22 located in the upper row of the third sub-pixel unit 213, and part of the break 25 is located on the lower side of the third sub-pixel unit 213, that is, part of the break 25 is opened between the third sub-pixel unit 213 and the optical sensor 22 located in the lower row of the third sub-pixel unit 213. This can reduce the reflection of the touch pattern on the light of the third sub-pixel unit above the partial optical sensor, and reduce the reflection of the touch pattern on the light of the third sub-pixel unit below the partial optical sensor, thereby reducing the interference of the light of the pixel unit reflected by the touch pattern on the optical sensor, thereby improving the signal-to-noise ratio of the optical sensor.

[0082] Specifically, as shown in FIG6 , in a column of third sub-pixel units 213, along the second direction 242, some of the cutouts 25 are located between the third sub-pixel unit 213 and the optical sensor 22 located in the row above the third sub-pixel unit 213, while others are located between the third sub-pixel unit 213 and the optical sensor 22 located in the row below the third sub-pixel unit 213. This results in some optical sensors 22 in a column having no touch patterns on either side, thus preventing interference from light reflected from the touch patterns on the third sub-pixel units. However, some optical sensors 22 have touch patterns on both sides. However, this embodiment can still reduce interference from light reflected from the pixel units by the touch patterns on the optical sensors, thereby improving the signal-to-noise ratio of the optical sensors.

[0083] Specifically, in two adjacent columns of third sub-pixel units 213, along the second direction 242, in one column of third sub-pixel units 213, all the breaks 25 are opened between the third sub-pixel units 213 and the optical sensors 22 located in the upper row of the third sub-pixel units 213, and in another column of third sub-pixel units 213, all the breaks 25 are opened between the third sub-pixel units 213 and the optical sensors 22 located in the lower row of the third sub-pixel units 213, so that one column of optical sensors will not receive the reflection of light from the touch pattern on the third sub-pixel units below some optical sensors, and one column of optical sensors will not receive the reflection of light from the touch pattern on the third sub-pixel units above some optical sensors, thereby reducing the interference of the light from the pixel units reflected by the touch pattern on the optical sensors and improving the signal-to-noise ratio of the optical sensors.

[0084] In some embodiments, as shown in FIG3 , the area of ​​the first sub-pixel unit 211 is larger than the area of ​​the second sub-pixel unit 212 .

[0085] In the first pixel row 511, the touch pattern 23 is not provided between the optical sensor 22 and its adjacent first sub-pixel unit 211, but the touch pattern 23 is provided between the optical sensor 22 and its adjacent second sub-pixel unit 212. By not providing a touch pattern between the optical sensor and its adjacent first sub-pixel unit, interference between the touch pattern and other structures caused by a small distance between the optical sensor and the first sub-pixel unit can be avoided, and interference of light from the first sub-pixel unit reflected by the touch pattern on the optical sensor can be avoided.

[0086] Specifically, as shown in FIG3 , the second line segment 232 includes a first subsegment 232a arranged along a first direction 241 and a second subsegment 232b arranged along a second direction 242.

By arranging the second subsegment between the optical sensor and the second sub-pixel unit in the first direction, interference with the optical sensor caused by light from the first sub-pixel unit reflected by the touch pattern can be avoided.

[0087] In some embodiments, as shown in FIG9 , the area of ​​the first sub-pixel unit 211 is larger than the area of ​​the second sub-pixel unit 212 .

[0088] In the first pixel row 511, the touch pattern 23 is not provided between the optical sensor 22 and the adjacent second sub-pixel unit 212, but the touch pattern is provided between the optical sensor 22 and the adjacent first sub-pixel unit 211. By not providing a touch pattern between the optical sensor and the second sub-pixel unit, interference with the optical sensor by light from the second sub-pixel unit reflected by the touch pattern can be avoided.

[0089] Specifically, as shown in FIG9 , the second line segment 232 includes a first subsegment 232a arranged along a first direction 241 and a second subsegment 232b arranged along a second direction 242. In the first direction 241, the second subsegment 232b is located between the optical sensor 22 and the first sub-pixel unit 211, and in the second direction 242, the first subsegment 232a is located between the first sub-pixel unit 211 and the second sub-pixel unit 212. By arranging the second subsegment between the optical sensor and the first sub-pixel unit in the first direction, interference with the optical sensor caused by light reflected from the second sub-pixel unit by the touch pattern can be avoided.

[0090] In some embodiments, as shown in FIG10 , the area of ​​the first sub-pixel unit 211 is larger than the area of ​​the second sub-pixel unit 212 .

[0091] In one of the first pixel columns 521, the touch pattern 23 is not arranged between the optical sensor 22 and its adjacent first sub-pixel unit 211, and the touch pattern 23 is not arranged between the optical sensor 22 and its adjacent second sub-pixel unit 212; in an adjacent second pixel column 522, the touch pattern 23 is arranged between the optical sensor 22 and its adjacent first sub-pixel unit 211, and the touch pattern 23 is arranged between the optical sensor 22 and its adjacent second sub-pixel unit 212.

[0092] Specifically, as shown in FIG10 , the second line segment 232 includes a first subsegment 232a arranged along a first direction 241 and a second subsegment 232b arranged along a second direction 242. In the first direction 241, part of the second subsegment 232b is located between the optical sensor 22 and the first sub-pixel unit 211, and part of the second subsegment 232b is located between the optical sensor 22 and the second sub-pixel unit 212. In the second direction 242, the first subsegment 232a is located between the first sub-pixel unit 211 and the second sub-pixel unit 212. By arranging part of the second subsegment between the optical sensor and the second sub-pixel unit, and part of the second subsegment between the optical sensor and the first sub-pixel unit, in the first direction, interference of light from part of the first sub-pixel unit and part of the second sub-pixel unit reflected by the touch pattern on the optical sensor can be avoided.

[0093] Specifically, Figure 10 illustrates an example in which the second line segment 232 arranged along the second direction 242 is located in the same column of two adjacent columns, but the embodiments of the present application are not limited to this. For example, in the first direction 241, the second sub-segment 232b can be arranged in different columns of two adjacent columns, and part of the second sub-segment 232b is located between the optical sensor 22 and the second sub-pixel unit 212, and part of the second sub-segment 232b is located between the optical sensor 22 and the first sub-pixel unit 211.

[0094] 3 , in one of the first pixel columns 521, the touch pattern 23 is disposed between the first sub-pixel unit 211 and the second sub-pixel unit 212. By disposing the touch pattern between the first sub-pixel unit and the second sub-pixel unit, various parts of the touch pattern can be connected together.

[0095] In some embodiments, as shown in Figures 3 and 5 (the first end C and the second end D are not marked in Figure 5), the first end C of the first line segment 231 is connected to one end of a second line segment 232, and the second end D of the first line segment 231 is connected to one end of another second line segment 232. By connecting the two ends of the first line segment 231 to the two ends of the two second line segments respectively, the end of the first line segment 231 can be prevented from extending out of the connection between the first line segment 231 and the second line segment 232, thereby avoiding the problem of tip discharge in the touch pattern.

[0096] Specifically, as shown in Figures 3 and 5, some of the first line segments 231 in the touch pattern 23 will be connected to three second line segments 232, and some of the first line segments 231 will be connected to four second line segments 232. However, no matter which first line segment 231 it is, its disconnected ends will be connected to the second line segments 232. The embodiment of the present application ensures that the two ends of the first line segment 231 are not left hanging, thereby avoiding the problem of tip discharge in the touch pattern and improving the yield of the display panel.

[0097] Specifically, the positions of the first end C and the second end D can be swapped.

[0098] In some embodiments, as shown in FIG7 , the first end C of the first line segment 231 is connected to one end of the second line segment 232, and one end of the second line segment 232 is connected to a first point E on the first line segment 231. The width L of the portion from the first point E on the first line segment 231 to the second end D of the first line segment 231 is greater than zero. By connecting one end of the first line segment to one end of the second line segment, leaving the other end of the first line segment suspended, a break is provided in the touch pattern between the third sub-pixel unit and the optical sensor when process limitations or process errors occur. This reduces the width of the touch pattern between the third sub-pixel unit and the optical sensor, thereby reducing interference with the optical sensor caused by light from the pixel unit reflected by the touch pattern and improving the signal-to-noise ratio of the optical sensor. This also prevents the problem of the first and second line segments being disconnected due to process errors, resulting in signal transmission failure.

[0099] Specifically, as shown in Figure 7, it can be seen that at both ends of the first line segment 231, the first end C of the first line segment 231 is connected to one end of the second line segment 232, and the other end of the first line segment 231 is suspended. The first point E on the first line segment 231 is connected to another second line segment to prevent the line from breaking, and the other end of the first line segment is suspended to prevent the connection between the first line segment and the second line segment from being disconnected, resulting in the problem of signal transmission failure.

[0100] Specifically, as shown in FIG7 , it can be seen that in a column of third sub-pixel units 213, the left ends of some first line segments 231 are suspended, and the right ends of some first line segments 231 are suspended. However, embodiments of the present application are not limited to this. For example, the left ends of all first line segments may be suspended, or the right ends of all first line segments may be suspended, or the left ends of a column of first line segments may be suspended, and the right ends of a column of first line segments may be suspended. Furthermore, in FIG7 , all first line segments have one end suspended, but embodiments of the present application are not limited to this. Only one end of some first line segments may be suspended.

[0101] In some embodiments, as shown in FIG8 , one second line segment 232 is connected to the second point F on the first line segment 231, and another second line segment 232 is connected to the third point G on the first line segment 231. The width L1 of the portion between the second point F on the first line segment 231 and either end of the first line segment 231 (e.g., first end C) is greater than 0, and the width L2 of the portion between the third point G on the first line segment 231 and either end of the first line segment 231 (e.g., second end D) is greater than 0. By leaving both ends of the first line segment suspended, a break is provided in the touch pattern between the third sub-pixel unit and the optical sensor when process limitations or process errors occur. This reduces the width of the touch pattern between the third sub-pixel unit and the optical sensor, thereby reducing interference with the optical sensor caused by light from the pixel unit reflected by the touch pattern and improving the signal-to-noise ratio of the optical sensor. This also prevents the first and second line segments from being disconnected due to process errors, leading to signal transmission failure.

[0102] Specifically, as shown in Figure 8, it can be seen that both ends of the first line segment 231 are suspended in the air, the second point F on the first line segment 231 is connected to a second line segment to prevent disconnection, and the third point G on the first line segment 231 is connected to another second line segment to prevent disconnection. In addition, the two ends of the first line segment are suspended in the air to prevent the connection between the first line segment and the second line segment from being disconnected, resulting in the problem of signal transmission failure.

[0103] Specifically, as shown in FIG8 , it can be seen that in the first line segments 231 surrounding all the third sub-pixel units 213 , both ends of all the first line segments 231 are suspended in the air, but the embodiment of the present application is not limited thereto, and only both ends of some of the first line segments 231 may be suspended in the air.

[0104] In some embodiments, the luminous color of the first sub-pixel unit is blue, the luminous color of the second sub-pixel unit is red, and the luminous color of the third sub-pixel unit is green, but the embodiments of the present application are not limited to this. For example, the luminous color of the first sub-pixel unit can be red or green, the luminous color of the second sub-pixel unit can be blue or green, and the luminous color of the third sub-pixel unit can be red or blue.

[0105] In some embodiments, the orthographic projection area of ​​the first sub-pixel unit is larger than the orthographic projection area of ​​the second sub-pixel unit, and the orthographic projection area of ​​the second sub-pixel unit is larger than the orthographic projection area of ​​the third sub-pixel unit. If the luminous efficiency of each sub-pixel unit is different, the orthographic projection area of ​​each sub-pixel unit can be made different. By setting sub-pixel units of different sizes, the luminous effect of each sub-pixel unit in the pixel unit is made the same.

[0106] In some embodiments, as shown in FIG. 4 , the display panel 1 includes a pixel definition layer 311 , an encapsulation layer 312 , and a planarization layer 315 . The touch layer 32 may include a first insulating layer 313 , a second insulating layer 314 , and touch electrodes 44 .

[0107] Specifically, the display panel includes an OLED display panel.

[0108] Specifically, the embodiments of the present application do not limit the specific structure of each sub-pixel unit. Each sub-pixel unit may include a pixel electrode layer, a light-emitting layer and a common electrode layer, and may also include a thin film transistor array layer that controls the sub-pixel unit.

[0109] Specifically, for the cross-sectional views in other drawings, reference may be made to the cross-sectional schematic diagrams of FIG3 and FIG4 , which will not be described in detail here.

[0110] Specifically, the above embodiments respectively describe the design of the display panel from the perspectives of the number of fractures, the positions of the fractures, the arrangement of the two ends of the first line segment, and the arrangement of the second line segment. It is understandable that when there is no conflict between the embodiments, the embodiments can be combined. For example, in a certain embodiment, some of the first line segments can adopt the design shown in FIG3, some of the first line segments can adopt the design shown in FIG5, some of the first line segments can adopt the design shown in FIG6, some of the first line segments can adopt the design shown in FIG7, some of the first line segments can adopt the design shown in FIG8, some of the second line segments can adopt the design shown in FIG8, some of the second line segments can adopt the design shown in FIG9, and some of the second line segments can adopt the design shown in FIG10. That is, the embodiments of the present application may include a combination of any multiple embodiments.

[0111] Specifically, taking the structures of the display panels shown in FIG. 1 and FIG. 3 as examples for comparison, the following Table 1 is obtained:

[0112] Table 1 Comparison of signal-to-noise ratios of optical sensors for different display panels

[0113]

[0114] As can be seen from Table 1, DOT noise represents the noise caused by the light of the pixel unit reflected by the touch pattern, internal noise refers to the noise caused by other structures, and noise + signal represents the sum of all noise and the effective signal of the light sensor. It can be understood that since the present application removes part of the touch pattern, the noise caused by other structures through the touch pattern is reduced. Therefore, the internal noise of the display panel shown in Figure 3 is reduced. It can be seen from Table 1 that the noise caused by the light of the pixel unit reflected by the touch pattern in the present application is reduced compared to the noise caused by the light of the pixel unit reflected by the touch pattern of the display panel shown in Figure 1. It can be seen from the signal-to-noise ratio SNR that the signal-to-noise ratio of the optical sensor of the display panel shown in Figure 1 is 1.38, and the signal-to-noise ratio of the optical sensor of the display panel shown in Figure 3 of the present application is 3.01, which improves the signal-to-noise ratio of the optical sensor of the embodiment of the present application.
