Problems solved by technology

As the size of the display device increases, the corresponding touch signal lines 10 increase accordingly, and the (horizontal and vertical) width of the signal line confluence area 13 increases, resulting in an increase in the width of the lower frame area 11 and the bending area, which is not conducive to Narrow downborder design; and display device production requires more space, which affects panel yield
[0004] Therefore, it is necessary to provide a display panel with an ultra-narrow frame to improve the problem of large frame width in the prior art

Abstract

The invention provides a display panel, which comprises a plurality of touch sensing chains, each touch sensing chain is provided with a corresponding touch routing area, each touch routing area is independently routed to be connected with a touch integrated circuit, and all the touch routing areas do not need to be gathered in a lower frame area. The touch wiring areas are arranged above the low-voltage wiring area VSS and the high-voltage wiring area VDD respectively, so that the width of the left lower frame area and the right lower frame area of the display panel can be reduced, the narrowframe of the large-size display panel is facilitated, the VDD and the VSS are both direct current (DC) signal sources, direct current signals cannot penetrate through capacitors, crosstalk cannot begenerated on the signal lines, the array substrate and the array substrate can reduce the influence of signal crosstalk.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel with an ultra-narrow frame. Background technique [0002] At present, display device technologies mainly include liquid crystal display, plasma display panel, organic electroluminescence and active matrix organic electroluminescence, which have broad application space in vehicles, mobile phones, tablets, computers and television products. The touch function has become one of the standard configurations of many display devices, among which capacitive touch screens are widely used. The formed electrical signal is used to confirm whether the panel is touched and to obtain the touch coordinates. [0003] An important touch technology of capacitive touch panel is self-capacitance, such as figure 1 Shown is a schematic diagram of a common touch structure design. The touch signal lines 10 converge at the lower frame area 11. In order to reduce signal interference, th...
