Embodiment 1

[0066] Embodiment 1 provides a display panel 100, by arranging the touch wiring 105 around each pixel light-emitting area 106, and the projection of the touch wiring 105 on the display layer 102 and the GOA signal line 104 Overlapping, the touch wiring 105 avoids overlapping with the pixel display area, so as to improve the light transmittance of the display panel 100 .

[0067] Such as Figure 5 As shown, Embodiment 2 of the present invention also provides a display panel 100a, which is different from Embodiment 1 in that the touch trace 105a forms at least one gap 107a, and the gap 107a is located in two adjacent pixel light emitting regions. between 105a. This can reduce the light-shielding area of ​​the touch trace 105a and improve light transmission.

[0068] According to the characteristic of the lowest brightness of blue light, Embodiment 2 is superior to disposing the notch 107a around the blue light emitting region 1063a, and the touch trace 105a surrounds at least ...

Embodiment 4

[0080] Embodiment 4 In order to avoid visible reflections at different positions caused by different metal densities, a disappearing layer 104c can be added on the touch layer 103c to eliminate visible metal reflections, which can further reduce metal light blocking and improve the display performance of the panel.

Abstract

The invention provides a display panel. The display panel comprises a substrate, a display layer and a touch layer. According to the display panel, touch wires are arranged around each pixel display region, and projection of the touch wires on the display layer is overlapped with GOA signal lines, so that the touch wires are prevented from being overlapped with the pixel display regions, and the light transmittance of the display panel is improved.

Description

technical field [0001] The present invention relates to the technical field of touch display, in particular to a display panel. Background technique [0002] As electronic products become more and more intelligent, the requirements for OLED display panels are also getting higher and higher, especially the under-screen fingerprint recognition technology puts forward higher requirements for the opening of OLED pixels, combined with the DOT (DirectOncell Touch) under development In the current technology, the touch metal wires are directly arranged on the packaging layer of the panel, so the difficulty is greatly increased. [0003] In order to avoid the loss of the display aperture ratio, the metal grid lines of the DOT need to avoid the light-emitting opening area of ​​the pixel, but the metal lines in the display area are densely packed and the light transmittance is low, which makes it difficult for fingerprint recognition under the light-sensitive screen .
