Abstract

The invention relates to the technical field of touch, in particular to the field of metal grid touch screens, and particularly relates to a metal grid structure and a touch screen. The metal grid structure comprises a first touch control electrode, an insulating layer located on the first touch control electrode and a second touch control electrode located on the insulating layer and on the surface of the side, away from the first touch control electrode, of the insulating layer. The first touch electrode comprises a first grid block and a second grid block, and the second touch electrode comprises a third grid block and a fourth grid block. The metal reflective stripes of the touch screen adopting the metal grid structure are extremely weak, and the optical performance is good; comparedwith a traditional ITO touch screen, the metal grid touch screen has universality, the metal grid touch screen is suitable for various touch screen production processes such as a yellow light process,a metal transfer process and laser etching, the price of materials for forming the metal grid is low, expensive ITO materials do not need to be used, and the cost is low.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to the field of metal grid touch screens, and in particular to a metal grid structure and a touch screen. Background technique [0002] The traditional OGS touch screen uses indium tin oxide (ITO) to make the touch electrode layer. The resistivity of the sheet resistance of indium tin oxide (ITO) usually ranges from tens to hundreds of ohms, because of its large resistance and high conductivity. Not good, the current noise is relatively large. After the OGS touch screen is combined with the LCM display, the finished product will also add the noise brought by the LCM display, which will affect the touch sensitivity. Indium tin oxide (ITO) is used as the touch electrode. The material is expensive, which increases the production cost of the touch screen; and the temperature required for the high-temperature coating of indium tin oxide (ITO) is about 400° C., the energy consumption is hi...
