Problems solved by technology

For example, the transmitting electrode of the touch sensor intersects with the sensing signal line layer of the light control sensor to form a parasitic capacitance, and the receiving electrode of the touch sensor intersects with the gate electrode layer of the light control sensor to form a parasitic capacitance. Mutual crosstalk will affect the integrated synchronous work of light control sensors and touch sensors

Abstract

The invention discloses a display module and a display device, the display module comprises a display panel and a sensing assembly arranged on the display panel, the sensing assembly comprises a light-operated sensor, the light-operated sensor comprises a gate electrode layer and a sensing signal line layer arranged above the gate electrode layer; a spacing layer which is arranged on the sensing signal line layer; a touch sensor which comprises a first electrode group arranged below the spacing layer and a second electrode group arranged on the spacing layer; a shielding part which is arranged below the spacing layer and is positioned between the first electrode group and the light-operated sensor; according to the display module, signal crosstalk between the light-operated sensor and the touch sensor is effectively reduced, meanwhile, the touch sensor and the light-operated sensor keep high-frequency scanning work, and the composite function that the display module synchronously integrates touch control and light control is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display module and a display device with the display module. Background technique [0002] With the development of large-size display technology and its wide application in various fields, it is also a mainstream trend to be developed to integrate various sensors into the display panel, especially touch sensors and light control sensors. In the current display devices, most of them use touch sensors, especially in small-sized mobile phones, and it is still relatively rare to integrate touch and light control synchronously in display devices. With the simultaneous demand for display devices such as light control and the development of human-computer interaction, synchronous integration of touch control and light control has become an inevitable trend in the development of display technology. [0003] At present, in a display device that synchronously integrates touch control a...
