Abstract

A display panel, including: a pixel structure constituted by a plurality of sub-pixels, wherein sub-pixels in each row are arranged in alignment, sub-pixels in every two adjacent rows are spaced in a column direction by a distance of X sub-pixels, 0<X<1, and a color of each sub-pixel differs from a color of an adjacent sub-pixel; a plurality of data lines arranged at column gaps between the sub-pixels; a plurality of touch signal lines arranged at gaps between the sub-pixels, wherein the plurality of touch signal lines are arranged in a different layer from the plurality of data lines and are insulated from the plurality of data lines; and a plurality of touch detection electrodes connected with the plurality of touch signal lines. A method for manufacturing the above display panel and a display device.

Claims

1. A display panel, comprising:

a pixel structure constituted by a plurality of sub-pixels, wherein sub-pixels, which are adjacent in a column direction, in every two adjacent rows are spaced in a row direction by a distance of X sub-pixels, 0<

X <

1, and a color of each sub-pixel differs from a color of an adjacent sub-pixel;

data lines and touch signal lines arranged at column gaps between the sub-pixels, wherein the touch signal lines and the data lines are insulated from each other; and

a plurality of touch detection electrodes connected with the plurality of touch signal lines,

wherein the touch signal lines and the data lines are arranged in different layers,

wherein within a column gap of a same sub-pixel, an orthographic projection of a data line on a substrate covers an orthographic projection of a touch signal line,

wherein the plurality of touch detection electrodes are re-used as a common electrode layer, and

wherein a film layer where the plurality of touch signal lines locate is located between a film layer where the plurality of data lines locate and the common electrode layer.

2. The display panel as claimed in claim 1, wherein extending directions of the plurality of touch signal lines are consistent with extending directions of the plurality of data lines.

3. The display panel as claimed in claim 1, wherein sub-pixels in two spaced rows are arranged in alignment in the column direction.

4. The display panel as claimed in claim 1, wherein each of the plurality of data lines is only connected with pixel switches of sub-pixels having a same color and being located at different sides.

5. The display panel as claimed in claim 1, wherein each of the plurality of data lines is connected with pixel switches of sub-pixels located at a same side.

6. A display device, comprising the display panel as claimed in claim 1.

7. The display device as claimed in claim 6, wherein extending directions of the plurality of touch signal lines are consistent with extending directions of the plurality of data lines.

8. The display device as claimed in claim 6, wherein sub-pixels in two spaced rows are arranged in alignment in the column direction.

9. The display device as claimed in claim 6, wherein each of the plurality of data lines is only connected with pixel switches of sub-pixels having a same color and being located at different sides.

10. The display device as claimed in claim 6, wherein each of the plurality of data lines is connected with pixel switches of sub-pixels located at a same side.

11. A method for manufacturing the display panel as claimed in claim 1, comprising:

forming patterns of gate, gate insulating layer, active layer, and data line on a substrate successively;

forming a first insulating layer on the pattern of data line;

forming a pattern of touch signal line on the first insulating layer;

forming a resin layer on the pattern of touch signal line, and forming patterns of resin layer and first insulating layer through one patterning process; and

forming patterns of pixel electrode and common electrode layer that are insulated from each other on the pattern of resin layer.
