The light emitting layer 12 includes a plurality of pixel units 120 arranged at intervals, the pixel units 120 are located in the display region 101, and each pixel unit 120 includes at least one sub-pixel.
The touch function layer 2 includes a touch electrode layer 20 and a touch signal wiring layer 22 disposed on the display substrate 1. The touch signal wiring layer 22 and the touch electrode layer 20 are disposed on the same layer.
The touch electrode layer 20 includes a plurality of touch sensing blocks 201, and at least a portion of the touch sensing blocks 201 is located in the display area 101. It should be noted that the touch sensing block 201 may be partially located in the display area 101, or may be entirely located in the display area 101. Preferably, the touch sensing block 201 is located entirely within the display area 101. Therefore, touch operation can be performed in the display area 101 of the display panel, and the range of touch induction is enlarged.
In this embodiment, the touch sensing blocks 201 form a matrix arrangement with M rows and N columns, wherein the touch sensing blocks 201 in the 1 st row to the M-1 st row have the same size, the touch sensing blocks 201 in the M th row have the same size, and the size of the touch sensing block 201 in the M th row is smaller than that of the touch sensing blocks 201 in the remaining rows. The touch sensing blocks 201 in the bottom row of the display area 101 are reduced in size to leave a space required by the fan-out area 110 in the display area 101.
The touch signal routing layer 22 includes a plurality of signal routing lines 221, the plurality of signal routing lines 221 correspond to the plurality of touch sensing blocks 201 one to one and are electrically connected to the plurality of touch sensing blocks 201, and the plurality of signal routing lines 221 extend to the bonding area 105 and are connected to the driving integrated circuit in the bonding area 105. The signal trace 221 connects the touch sensing block 201 and the driving integrated circuit, so as to realize the transmission of the touch signal. The driving integrated circuit may be a touch driving circuit, or may be a combination of the touch driving circuit and a display driving circuit.
The touch functional layer 2 includes a fan-out region 110, and at least a portion of the fan-out region 110 is located in the display region 101, so that the signal traces 221 are collected in the display region 101, and therefore, the space required by the signal traces 221 in the frame region 103 is reduced. Therefore, the height of the frame of the touch display panel 100 in the second direction can be reduced, and a narrow frame design is realized. Preferably, as shown in fig. 1, the fan-out area 110 is located entirely within the display area 101, i.e. the display area 101 covers the fan-out area 110.
The signal trace 221 includes a first portion of signal trace 222 and a second portion of signal trace 224. In this embodiment, the first portion of the signal trace 222 includes a longitudinal section 232 extending along the first direction and a collection section 234 extending along the second direction, an end of the collection section 234 extends to the bonding region 105, the longitudinal section 232 intersects the collection section 234, and both the longitudinal section 232 and the collection section 234 are located in the display region 101. In this embodiment, the collecting section 234 is located at a side of the touch sensing block 201, which is close to the frame area 103, of the row of the touch sensing blocks 201 conducted with the collecting section. The second part of the signal traces 224 of the signal traces 221 extend straight to the fan-out area 110 to the border area 103. In the present embodiment, the first direction is perpendicular to the second direction.
In order to eliminate the viewing angle Mura phenomenon caused by the reflection angle between the signal trace in the fan-out area 110 and the signal trace 221 in other areas, a redundant metal pad 225 is disposed below the row of touch sensing blocks 201 that are electrically connected to the signal trace. The redundant metal pad 225 is only used to eliminate the difference caused by the reflection angle of the signal trace and does not participate in the conduction.
Two adjacent signal wires 221 are arranged in parallel to form a wire pair 231, a plurality of first light-emitting holes 233 are formed between each wire pair 231, a plurality of second light-emitting holes 235 are formed between adjacent wire pairs, each first light-emitting hole 233 corresponds to at least one pixel unit 120, and each second light-emitting hole 235 corresponds to at least one pixel unit 130. The influence on the display effect caused by the signal wiring 221 shielding the sub-pixels is avoided. Compared with the prior art that the pixel unit is bypassed by one signal trace, in the embodiment, the two signal traces 221 are oppositely arranged and avoid the pixel unit 120, so that the space of the display area 101 occupied by each signal trace 221 can be reduced, and the space occupation ratio of the touch sensing block 201 is improved.
It should be noted that the first light exit hole 233 and the second light exit hole 235 may correspond to one pixel unit 120, or may correspond to a plurality of pixel units 120, that is, one light exit hole surrounds a plurality of pixel units 120. The shapes of the first light emitting hole 233 and the second light emitting hole 235 may be determined according to the shape of the pixel unit 120, and in this embodiment, the first light emitting hole 233 and the second light emitting hole 235 are both in a central symmetrical pattern.
Specifically, the signal trace 221 includes a plurality of first connecting segments 241 and second connecting segments 242 connected in sequence, where the first connecting segments 241 are straight segments, the second connecting segments 242 are curved segments, each second connecting segment 242 is located between two adjacent first connecting segments 241, two first connecting segments 241 of two adjacent signal traces 221 are disposed oppositely, and two second connecting segments 242 of two adjacent signal traces 221 are disposed oppositely. In the present embodiment, the second connection segment 242 has a circular arc shape or a semicircular shape.
The light shielding layer 3 includes a plurality of light shielding patterns 30, and the light shielding patterns 30 cover the surface of the signal trace 221 in the display region. The light-shielding layer 3 exposes the pixel unit 120. Because the converging section 234 extends along the second direction, the reflection angle of the converging section 234 to the external environment light is different from the reflection angle of the longitudinal section 232 to the external environment light, so the light shielding layer 3 is arranged on the surface of the whole signal wiring 221, the uneven brightness phenomenon caused by the change of the trend of the signal wiring 221 is directly eliminated, and the display effect is improved.
In this embodiment, the light-shielding layer 3 also covers the surface of the touch electrode layer 20, so that the phenomenon of uneven brightness caused by reflection of the touch sensing block 201 can be eliminated.
In the present embodiment, the flat layer 4 is provided on the surfaces of the light-shielding layer 3 and the flat layer 4. The planarization layer 4 may be a film made of an insulating material, for example, an insulating film made of Organic resin (OC).
Referring to fig. 5, the touch display panel shown in fig. 5 is substantially the same as the touch display panel 100 of the first embodiment, and the difference is that in this embodiment, the shape of the second connection section 252 included in the signal trace 250 is slightly different from that of the first embodiment, in this embodiment, the second connection section 252 is formed by sequentially connecting three branch sections, specifically, the second connection section 252 includes a first branch section 255 and second branch sections 253 located at two ends of the first branch section 255, the length of the first branch section 255 is smaller than that of the second branch section 253, and the shape of the two second connection sections 252 formed by opposing each other is a rhomboid. That is, the first connection segment 251 is used for connection, and the second connection segment 252 is used for bypassing the pixel unit 130. So that the pixel cells 120 may also be diamond shaped. It can be understood that the light shielding layer is formed on the entire surface of the signal trace 250.
Referring to fig. 6, the touch display panel 200 shown in fig. 6 is substantially the same as the touch display panel 100 of the first embodiment, and the difference is that in this embodiment, the touch signal wiring layer 22 and the touch electrode layer 20 included in the touch function layer 210 are stacked, and the insulating layer 5 is disposed between the touch signal wiring layer 22 and the touch electrode layer 20 and is conducted through the conductive via 25, so as to connect the signal wirings 221 included in the touch signal wiring layer 22 and the touch sensing blocks 201 included in the touch electrode layer 20. And the distance between the touch signal wiring layer 22 and the substrate 10 is greater than the distance between the touch electrode layer 20 and the substrate 10. The light shielding layer 31 is located on the surface side of the touch signal wiring layer 22, and the projection of the touch sensing block 201 included in the touch electrode layer 20 is located in the projection range of the light shielding pattern 301 included in the corresponding light shielding layer 31 on the substrate 10, so that the light shielding layer 31 can eliminate the poor vision phenomenon caused by the reflection generated by the touch sensing block 201.
Moreover, since the touch signal wiring layer 22 and the touch electrode layer 20 are disposed on different layers, the signal wiring 221 is prevented from occupying the space of the touch sensing block 201 in the display area 101, thereby ensuring the touch performance. It should be noted that the fan-out area 110 may be partially located in the display area 101, or may be entirely located in the display area 101.
Referring to fig. 7, the touch display panel 300 shown in fig. 7 is substantially the same as the touch display panel 100 of the first embodiment, except that in the present embodiment, the shape of the signal trace 330 is slightly different from the shape of the signal trace 221.
In this embodiment, a pair of protruding pillars 342 extends from a side of the second connecting section 340 facing away from the other second connecting section 340, each protruding pillar pair 342 includes two spaced protruding lugs 341, and a gap d between the protruding lugs 341 is the same as a gap between the two first connecting sections 331, so that the protruding pillar pair 342 rotates by a certain angle to be overlapped with the first connecting sections 331, and the protruding pillar pairs 342 of adjacent signal traces 330 are spaced. The pair of posts 342 is formed simultaneously with the signal trace 330.
In addition, compared to the light shielding layer formed on the surface of the entire signal trace in the first embodiment, in the present embodiment, the light shielding layer 41 is formed only on the surface of the first connecting section 331 included in the collecting section of the fan-out region, that is, the light shielding pattern 410 included in the light shielding layer 41 is formed on the surface of each first connecting section 331.
Since the partial signal traces 330 converge to the fan-out area 110 from the first direction, that is, the signal traces 330 are converted from vertical to horizontal extension, so that the reflection angle of the converging section 234 to the external environment light is different from the reflection angle of the longitudinal section 232 of the signal trace 221 to the external environment light, the first connecting section 331 of the converging section 234 is covered by the light shielding pattern 30, and the reflection of the first connecting section 331 of the converging section 234 to the light in the horizontal direction is eliminated.
The pair of protruding pillars 342 of the adjacent signal traces 330 also extend in the vertical direction, as shown by the dashed line box C in fig. 7, so that the arrangement of the plurality of converging sections 234 of the fan-out area in the longitudinal direction is consistent with the extending direction of the longitudinal section 232, that is, the shape difference between the adjacent signal traces 330 is reduced by using the pair of protruding pillars 342 to reduce the reflection difference between the light beams, thereby eliminating the brightness unevenness caused by the reflection angle of the signal traces of the fan-out area 110.
That is, in the embodiment, the light shielding layer is directly disposed at the position where the reflection difference occurs for elimination, and the convex pillar is used for reflection correction of the light shielding layer 342, so as to eliminate the uneven brightness phenomenon caused by the different reflection angles of the signal traces.
