Display panel and cabling structure thereof

Abstract

A display panel and a wiring structure thereof. The wiring structure comprises a plurality of metal wirings, the metal wirings being arranged in an extending manner on a first wiring region (21), a second wiring region (22) and a third wiring region (23) which are distributed continuously. The first wiring region (21) is located at the inner side of the second wiring region (22), the third wiring region (23) is located at the outer side of the second wiring region (22), and the second wiring region (22) is a frame sealant coating region of a display panel (20). The linewidth of the nth metal wiring arranged on the second wiring region (22) is a, and the line distance between the nth metal wiring and the (n+1)th metal wiring is b, wherein n≥1, and when the value of n adopts different numerical values, the ratio of a / (a+b) remains unchanged. In this way, the display panel and the wiring structure thereof can make the metal coverage ratio arranged on a frame sealant coating region unchanged, avoiding nonuniform curing of a frame sealant, which thereby influences the stability of a display panel.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and its wiring structure. Background technique [0002] In order to improve the display quality of the display panel, the impedance between the metal traces in the display panel will be reduced as much as possible. To achieve this goal, the line width of the metal traces can be changed. [0003] Such as figure 1 as shown, figure 1 It is a schematic diagram of the wiring structure of the display panel in the prior art. A plurality of metal wires are arranged in the frame glue coating area 12 of the display panel. Taking the N+1th metal wire, the Nth metal wire and the N-1th metal wire as examples, since the first The direction of the metal trace to the Nth metal trace (such as figure 1 In the direction A) indicated by the arrow in the figure, the distance of the metal trace increases, that is to say, the distance of the N+1th metal trace is longer than the dis...

Problems solved by technology

Under the condition that the line distance D between each metal line remains unchanged, since the width of the metal line increases, in the frame glue coating area 12, along figure 1 In the direction A, the metal coverage increases, so that the light transmittance of the frame glue coating area 12 will change, resulting in uneven curing of the frame glue and affecting the display quality of the LCD panel
