Problems solved by technology

[0005] Because the width ratio of the two is too large, the finger position corresponding to the minimum potential difference that can be detected by the existing technology (that is, the touch accuracy) is low, resulting in a decline in touch performance and experience

Abstract

The invention provides a display panel and a display device. The display panel comprises a first electrode layer and a second electrode layer, wherein the first electrode layer includes a plurality of first electrodes, which extend along a first direction and are arranged along a second direction; the second electrode layer includes a plurality of second electrodes, which extend along the second direction and are arranged along the first direction, and the second direction is vertical to the first direction; two adjacent first electrodes have a first center spacing; two adjacent second electrodes have a second center spacing; and the range of a ratio of the first center spacing to the second center spacing is 0.5 to 2. According to the display panel and the display device, through changing the width ratio of a touch driving electrode to a touch detection electrode, the display effect and the touch recognition performance are both considered, so that the touch performance and the touch experience of the panel are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device that improve the touch performance and experience of the panel. Background technique [0002] figure 1 It is a schematic cross-sectional view of a display panel in the prior art. Such as figure 1 As shown, an existing display panel with touch function includes a first substrate 10 ′, a first electrode layer 20 ′, a liquid crystal layer 30 ′, a second substrate 40 ′, and a second electrode stacked from bottom to top. Layer 50'. [0003] figure 2 It is a schematic diagram of the stacking of various film layers in the display panel of the prior art. Such as figure 1 and figure 2 As shown, the first electrode layer 20' is provided on the first substrate 10', and the first electrode layer 20' includes a plurality of first electrodes extending along the first direction (Y direction) and arranged along the second direction (X direct...
