Problems solved by technology

Among them, the frame portion of the cover glass plate and the frame portion of the OLED display panel have enough space to realize the narrow frame design, while the frame portion of the touch panel is mainly composed of signal lines, due to the line width of the signal line The limitation of the line spacing leads to the limitation of the narrow frame design of the total width of the signal line. Therefore, it is dif

Abstract

The invention discloses a touch panel, a touch display device and a manufacture method of the touch panel. The touch panel comprises a first substrate, a first conductive layer, touch electrodes, a second substrate and a second conductive layer, wherein the touch electrodes in a display area comprise a first touch electrode and a second touch electrode; a wiring area of the touch panel comprises signal wires used for transmitting touch signals; the signal wires comprise at least one first signal wire and at least one second signal wire; the first signal wires are electrically connected to the first conductive layer and are also electrically connected to the first touch electrode; the second signal wires are electrically connected to the second conductive layer and are also electrically connected to the second touch electrode; projections of the first signal wires and the second signal wires on the same side of the touch panel in the vertical direction of the first substrate are at least partially overlapped; the total width of the signal wires in the wiring area around the touch panel is greatly reduced; a good narrow bezel effect is exerted.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a touch panel, a touch display device and a method for manufacturing the touch panel. Background technique [0002] At present, the development trend of the touch display industry is developing toward narrow bezels. The design of narrow bezels can increase the size of the display area of ​​the display screen and bring better visual aesthetics to users. [0003] For the AMOLED (Active Matrix Organic Light Emitting Diode, active matrix organic light emitting diode) display screen with integrated touch function, the frame effect consists of the frame part (visible area VA and ink area) of the cover glass plate Cover lens, the touch area The frame part (peripheral wiring area) of the control panel and the frame part (peripheral circuit and packaging area) of the OLED display panel are determined. Among them, the frame portion of the cover glass plate and the frame portion o...
