Touch sensing module, touch panel and electronic equipment

Abstract

The invention relates to a touch sensing module, a touch panel and an electronic equipment. The touch sensing module comprises an elastic base material layer, a driving electrode layer and a sensing electrode layer, wherein the driving electrode layer and the sensing electrode layer are arranged on the elastic base material layer; the driving electrode layer and the sensing electrode layer respectively comprise at least two mutually independent sub-electrodes; the driving sub-electrodes and the induction sub-electrodes are metal grids, and metal wires in the metal grids are wavy; orthographic projections of the driving sub-electrodes and the induction sub-electrodes on the surface of the elastic base material layer are crossed. The driving electrode layer and the sensing electrode layer are arranged on the stretchable elastic base material layer, and the metal wires in the metal grid are wavy, so that when the touch sensing module is stretched, the metal wires in the metal grid are stretched from a wavy shape to a linear shape, and the stretchable performance of the touch sensing module is improved.

Description

technical field [0001] The present application relates to the field of touch technology, in particular to a touch sensing module, a touch panel and an electronic device. Background technique [0002] With the rapid development of intelligent electronic device technology, various touch sensing module products with touch panels appear in people's daily life, and their touch performance has become one of the focuses of people's attention. [0003] The main consumer electronic devices on the market can be divided into three types according to the screen form: the first is the device equipped with a flat display screen, such as Apple iphone XR, Huawei P30, OPPO R17, VIVO X27, etc. The display screen can use ordinary LCD screen or hard OLED screen. The touch solution can use In-cell, SITO, DITO and other technologies. These technologies are relatively mature, so this kind of equipment is also more cost-effective; Devices with curved screens, such as Samsung’s Galaxy Note 9, S10, ...

[0003] The main consumer electronic devices on the market can be divided into three types according to the screen form: the first is the device equipped with a flat display screen, such as Apple iphone XR, Huawei P30, OPPO R17, VIVO X27, etc. The display screen can use ordinary LCD screen or hard OLED screen. The touch solution can use In-cell, SITO, DITO and other technologies. These technologies are relatively mature, so this kind of equipment is also more cost-effective; Devices with curved screens, such as Samsung’s Galaxy Note 9, S10, Huawei Mate20 Pro, P30 Pro, etc., all use flexible OLED technology for their displays, and most of the touch solutions are SITO or Y-OCTA, which are mostly high-end products; The third is the emerging foldable screen devices, such as Roupai released by Royole, Galaxy Fold released by Samsung, and Mate X released by Huawei. With Y-OCAT technology, other terminals must adopt the external touch solution due to technical problems such as the low yield rate of the embedded touch solution of the screen factory, and the common external touch sensor modules currently use indium tin oxide ( Indium Tin Oxides, ITO) is used as a conductive material, but the ITO material is relatively brittle, not resistant to stretching, easy to break, and affects the touch performance of the product
