Abstract

The invention provides a display panel, a manufacturing method thereof and a display device. The display panel comprises a liquid crystal panel and a touch panel, the touch panel comprises a substrateand a plurality of touch sensors and light-operated sensors, each touch sensor is composed of a plurality of columns of transmitting electrodes and receiving electrodes, and each light-operated sensor comprises a plurality of gate electrodes; the receiving electrodes and the gate electrodes are arranged in a layered manner, and the orthographic projection areas of the plurality of receiving electrodes on the substrate are overlapped with the orthographic projection areas of the gate electrodes on the substrate to form a plurality of overlapping areas. Every two adjacent receiving electrodes,located in each overlapping area, in the same column of receiving electrodes are connected through a conductive electrode arranged on the side, away from a gate electrode, of the receiving electrode,so that parasitic capacitance between the receiving electrodes of the touch sensors and the gate electrodes of the light-operated sensors is reduced, the influence of the light-operated sensors on thesignal crosstalk of the touch sensors is reduced, and the touch accuracy and sensitivity of the display panel integrated with the light-operated sensors and the touch sensors are improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, it is also a trend to integrate sensors into display panels. The touch and light sensors currently used are to attach the sensor to the outside of the display panel, which will not only reduce the light transmittance of the display panel, but also increase the manufacturing cost, while integrating the sensor in the display panel can effectively reduce the The loss of light can also reduce manufacturing costs. [0003] In the existing display panels that synchronously integrate the light control sensor and the touch sensor, the touch sensor is usually a mutual capacitance structure, which is composed of multiple rows of emitting electrodes arranged horizontally and multiple columns of receiving electrodes arranged vertically, an...
