Abstract

The embodiment of the invention discloses a touch substrate and a display device. The touch substrate comprises a substrate body and a touch layer arranged on the substrate body. The touch layer comprises a plurality of touch units and a plurality of optical units, each touch unit comprises a touch sensing electrode, each optical unit comprises a signal reading line, the touch sensing electrodes and the signal reading lines are oppositely arranged, and each signal reading line is arranged between every two adjacent touch sensing electrodes, wherein the touch layer further comprises a signal shielding device arranged between the touch unit and the optical unit, and the signal shielding device is arranged close to the touch induction electrode or the signal reading line. According to the embodiment of the invention, the signal shielding device is arranged between the touch unit and the optical unit, so that the signal crosstalk between the touch sensing electrode and the reading line can be shielded, the signal-to-noise ratio is improved, the crosstalk between the light-operated sensor and the touch sensor is reduced, and the working performance of the touch substrate is improved.

Description

technical field [0001] The present invention relates to the field of display, in particular to a touch substrate and a display device. Background technique [0002] In recent years, synchronous integration of light control sensors and touch sensors is conducive to the thinning of touch substrates. However, for the current touch substrate that synchronously integrates the light control sensor and the touch sensor, when the light control sensor and the touch sensor work at the same time, it is easy to generate parasitic Capacitance causes signal crosstalk and affects the working performance of the touch substrate. [0003] Therefore, there is an urgent need for a touch substrate and a display device to solve the above technical problems. Contents of the invention [0004] Embodiments of the present invention provide a touch substrate and a display device, which can solve the problem of signal crosstalk between the electric wires of the touch sensor and the reading lines of...
