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 arranged on the liquid crystal panel,and the touch panel comprises a substrate and a plurality of touch sensors and light-operated sensors which are alternately arranged on the substrate in an array mode; each touch sensor is composed ofa plurality of columns of transmitting electrodes arranged at intervals in the first direction and a plurality of columns of receiving electrodes arranged at intervals in the direction perpendicularto the first direction, and each light-operated sensor comprises a plurality of gate electrodes arranged in an array mode. A first transparent organic film layer with a low dielectric constant is arranged between each receiving electrode of each touch sensor and each gate electrode of each light-operated sensor which are arranged in a layered manner, so that the distance between the receiving electrodes and the gate electrodes is increased, and the parasitic capacitance between the receiving electrodes and the gate electrodes is reduced; the influence of the light-operated sensors on the signal 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...
