Abstract

The present application proposes a touch substrate and a touch screen. The touch substrate includes a touch layer; the touch layer includes a first electrode and a second electrode. The first electrode includes a first bump and a first dummy electrode; the second electrode includes a second bump and a second dummy electrode. There is at least one sub-pixel space between two adjacent first protrusions or the second protrusions, and at least one sub-pixel space between the first dummy electrode and the second protrusions, the The second dummy electrode is at least one sub-pixel apart from the first protrusion. This application increases the mutual capacitance value between the first electrode and the second electrode by increasing the proportion of the dummy electrode to the corresponding electrode and the relative side length between the first electrode and the second electrode, and improves the It improves the capacitance variation of the multi-finger coaxial product under the floating touch, and enhances the touch sensitivity of the touch substrate.

Description

technical field [0001] The present application relates to the display field, in particular to a touch substrate and a touch screen. Background technique [0002] With the development of display technology, touch screens are more and more commonly used in electronic devices such as tablet computers and smart phones. Capacitive touch screens in the prior art are the most widely used in smart phones, tablet computers, etc. Traditional capacitive screens use indium tin oxide (Indium Tin Oxide, ITO) conductive film as the material of the touch electrodes. This type of capacitive screen has Disadvantages such as high price, large resistance value, and not easy to bend. The emergence of the metal mesh (Metal Mesh) technology makes up for the above-mentioned defects of the ITO touch electrode. [0003] At present, floating touch is a new type of touch technology, which allows users to complete operations on the mobile phone without touching the screen (that is, the touch screen is...
