Abstract

The invention relates to the field of display technologies, and provides a pressure sensing substrate and a pressure sensing touch screen, which aim to solve the problem of a complex structure of the conventional pressure sensing touch screen. The pressure sensing substrate comprises a substrate, a transparent electrode layer, and a plurality of elastic strain sensors, wherein the transparent electrode layer is arranged on the substrate, and comprises a plurality of transparent bar-shaped electrodes which are arranged in parallel; the elastic strain sensors are arranged on the transparent electrode layer, and each elastic strain sensor is in electrical contact with at least one transparent bar-shaped electrode; and the elastic strain sensors are deformed when pressed, and the bulk resistance of each elastic strain sensor changes with the deformation quantity of the elastic strain sensor. The pressure sensing substrate is applied in the pressure sensing touch screen and used for sensing pressures.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a pressure-sensitive substrate and a pressure-sensitive touch screen. Background technique [0002] As an intuitive and concise input device for computers and other data processing devices, the touch screen is widely used in various mobile devices. There are various types of touch screens, such as resistive, capacitive, optical, etc., that can detect single or multiple touch locations. [0003] The pressure-sensitive touch screen can not only sense the touch position, but also sense the touch pressure, so that different operations can be realized according to the size of the touch pressure, providing more powerful functions for the touch screen. At present, there are the following ways to realize the pressure sensing function: setting pressure sensors around the touch screen, and determining the pressing pressure according to the pressure measured by different sensors, but the ...
