Problems solved by technology

The border part of the TSP is mainly composed of signal traces 04. Due to the technical constraints of the minimum line width and line spacing of the signal traces, the width of the border area cannot be further compressed, making it difficult to reduce the total width of the signal lines. In fact, the design of TSP touch electrodes and signal wiring in the prior art makes the narrow frame design of display products have limitations

Abstract

The present application discloses a touch panel, a manufacturing method thereof, and a touch device, so as to make it easier for touch display products to realize narrow borders. A touch panel provided by an embodiment of the present application includes a display area and a non-display area. The display area includes: first touch electrodes extending along a first direction and second The touch electrode, the first signal line connected to the first touch electrode, and the second signal line connected to the second touch electrode; The driving circuit connected to the signal line and the second signal line; each first touch electrode includes a plurality of first grid-shaped electrode blocks connected in sequence along the first direction, and the orthographic projection of the first signal line on the substrate is the same as that of the second The orthographic projection of a touch electrode on the substrate has an overlapping area, and in the overlapping area, the orthographic projection of the first signal line on the substrate is within the range of the orthographic projection of the first grid electrode block on the substrate.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch panel, a manufacturing method thereof, and a touch device. Background technique [0002] At present, the development trend of the touch display industry is developing in the direction of ultra-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. Taking the Active-matrix organic light emitting diode (AMOLED) display with integrated touch function as an example, the frame effect is covered by the Thin Film Encapsulation (TFE) package frame part, the touch screen panel ( TouchScreen Panel, TSP) border part, the border decision on the AMOLED display panel, such as figure 1 As shown, the TSP includes: touch sensing electrodes (TX) 02 and touch driving electrodes (RX) 03 arranged in the display area 8 , RX signal lines 04 , TX signal lines 05 , and a TSP control chip...
