Problems solved by technology

But this approach is limited by the size
Because in the case of a large size, when the sensing electrode is made of indium tin oxide (ITO), the resistance of the sensing electrode is large, and the signal attenuation increases, making signal processing difficult. At the same time, the increase in resistance makes the scanning of the touch substrate difficult. frequency decrease
In order to prevent the large sensi

Abstract

The invention provides a touch substrate, a manufacturing method of the touch substrate and a touch display device. The touch substrate comprises a first electrode layer and a second electrode layer which are arranged on a lining substrate, wherein the first electrode layer comprises a plurality of first electrodes; the second electrode layer comprises a plurality of second electrodes; each first electrode comprises a plurality of first electrode units and first connecting parts which are connected between two adjacent first electrode units; each second electrode comprises a plurality of second electrode units and second connecting parts which are connected between two adjacent second electrode units; the first connecting parts and the second connecting parts are intersected; the first electrode units are transparent electrode blocks; the second electrode units are metal grid electrode blocks. The total resistance of electrodes on the touch substrate can be reduced, the manufacturing method can be suitable for manufacturing the touch substrate with large size, and meanwhile, the ripple effect is reduced.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch substrate, a manufacturing method of the touch substrate, and a touch display device including the touch substrate. Background technique [0002] As one of the most convenient human interaction technologies, touch technology has gradually penetrated into people's lives. The capacitive touch screen is an important form of the touch screen. The touch substrate of the capacitive touch screen includes a driving electrode layer and a sensing electrode layer. A plurality of driving electrodes of the driving electrode layer and a plurality of sensing electrodes of the sensing electrode layer cross each other. Capacitors are formed adjacent to the electrodes; each driving electrode is loaded with a driving signal in a scanning form, and a corresponding sensing signal is generated on the sensing electrode. The capacitance between them, so that the sensing signal of the cor...
