Problems solved by technology

However, a capacitive coupling effect occurs between the gate lines of the display panel and the touch elements, which affects the pixels that are passed by the wires electrically connected to the touch elements, so that stripe-like defects appear on the display screen corresponding to these pixels. , such as vertical stripes or horizontal stripes, among which the vertical stripes are the most obvious, making the visual effect of the display screen poor

Abstract

The invention provides a touch display panel, which includes a first substrate, a second substrate, a display medium layer, a membrane switch element layer, a touch electrode layer and a plurality of wires. The display medium layer is located between the first substrate and the second substrate, the membrane switch element layer is arranged between the first substrate and the display medium layer, and the touch electrode layer is arranged between the membrane switch element layer and the display medium layer, including a plurality of The touch electrodes are arranged in the display area of ​​the touch display panel. The wires are arranged on the inner surface of the first substrate and extend along a direction from the display area to the peripheral area, wherein each wire is respectively electrically connected to one of the touch electrodes, and each wire has the same length in the display area.

Description

Technical field [0001] The present invention relates to a touch display panel, in particular to a touch display panel that can avoid uneven brightness of the screen due to the capacitive coupling effect. Background technique [0002] With the popularity of consumer electronic devices, display panels with touch functions have been widely used in smart phones, digital cameras, multimedia players, and notebook computers. The traditional touch display panel is made separately from the touch panel and the liquid crystal display panel, and then the touch panel and the liquid crystal display panel are assembled together, so there are disadvantages such as heavier weight, higher cost, and lower light transmittance. In order to solve the above-mentioned shortcomings, it has recently been developed to fabricate touch elements and display elements on the same panel to form a display panel with touch function. The touch elements of the integrated touch display panel are arranged on the subs...
