Problems solved by technology

However, in the process of implementing the present application, the inventors found that there are at least the following problems in the prior art: because the size of the tip of the stylus is small, far smaller than the size of a finger, the coupling capacitance is small, and the touch sensitivity and accuracy are relatively small. The sensitivity is low, and the conventional touch screen cannot meet the needs of users for touch sensitivity.

Abstract

The invention provides a touch screen and electronic equipment. The touch screen comprises a base material and a first touch unit, and the base material is provided with a first face and a second face which are opposite; the first touch unit comprises a plurality of first conductive electrodes, a first insulating layer and a plurality of second conductive electrodes; the plurality of first conductive electrodes are arranged on the first surface and are arranged at intervals in a first direction; a plurality of first bridging electrodes are arranged between every two adjacent first conductive electrodes at intervals; the first bridging electrodes are arranged at intervals in the first direction; the first insulating layer covers the first conductive electrodes and is provided with a plurality of first via holes; the second conductive electrodes are arranged on the side, away from the base material, of the first insulating layer; the second conductive electrodes are arranged at intervals in a second direction; and each second conductive electrode is electrically connected with the plurality of first bridging electrodes through the first conducting holes, the second conductive electrodes are electrically connected with the bridging electrodes through the conducting holes of the first insulating layer, so that the effective area of the touch screen is increased, and a touch position can be accurately obtained.

Description

technical field [0001] The present application relates to the technical field of touch screens, in particular to a touch screen and electronic equipment. Background technique [0002] In recent years, with the gradual popularization of portable electronic devices such as mobile phones, tablet computers, and notebook computers, users have higher and higher requirements for the experience of electronic devices, especially the touch accuracy of electronic devices. [0003] The stylus is a capacitive pen based on a mutual capacitive touch screen design. Among them, the mutual capacitive touch screen sensor is to coat the touch circuit on both sides of the screen, and make the electrode matrix of the X axis and the Y axis according to the touch circuit, and the X / Y axis matrix is ​​coupled with each other to form mutual capacitance. At this time, the finger and the surface of the touch circuit form a coupling capacitance, which causes a slight change in the current, which is equ...
