Abstract

The invention proposes a display panel. The display panel comprises a substrate, a thin film transistor layer and a touch control layer, wherein the thin film transistor layer is arranged on the substrate, the touch control layer is arranged on the thin film transistor layer, the thin film transistor layer comprises a source-drain layer, a source / drain and a data signal line are arranged on the source-drain layer, the display panel also comprises a touch control wire, the touch control wire is electrically connected with the touch control layer and is arranged between the substrate and the touch control layer, and a part of data signal line and a part of touch control wire are not arranged at the same layer. A part, at relatively small distance with the data signal line, of the touch control wire is arranged on different film layers by a jumper design, short connection of the touch control wire and the data signal line is prevented, a data signal is normally transmitted, and the product yield is improved.

Description

technical field [0001] The invention relates to the display field, in particular to a display panel. Background technique [0002] Low temperature polysilicon (LTPS), due to its high electron mobility, can effectively reduce the area of ​​thin film transistor (Thin Film Transistor, TFT) devices, thereby increasing the aperture ratio of pixels and increasing the panel display Brightness can reduce the overall power consumption at the same time, so that the manufacturing cost of the panel is greatly reduced, and it has become a hot technology in the field of liquid crystal display. [0003] In the display panel in the prior art, in order to save the photomask, the touch leads and the source and drain layers are often arranged on the same layer. Due to the shortage of wiring space, the touch leads and the data lines are short-circuited, which affects the data transmission performance of the display panel, resulting in The abnormal display of the display panel reduces the yield...
