Abstract

The invention relates to the field of display screens, and especially discloses a capacitive screen capable of preventing display module interference and a preparation method thereof. The capacitive screen capable of preventing the display module interference comprises a display module, a shielding layer and a capacitive screen body. The display module, the shielding layer and the capacitive screen body are sequentially stacked, and a first conductive layer and a second conductive layer are arranged on the lower surface and the upper surface of the shielding layer respectively. The capacitivescreen effectively prevents signal interference of the display module on the edge channel of the capacitive screen.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a capacitive screen for preventing display module interference and a preparation method thereof. Background technique [0002] At present, the large-size full-fit capacitive screen adopts the structure of capacitive screen + full-fit glue + display module, because the most edge channel on the capacitive screen is greatly interfered by the radiation from the edge of the display module, and the edge of the capacitive screen is prone to appear The signal of the channel is unstable. Contents of the invention [0003] The object of the present invention is to provide a capacitive screen which prevents display module interference and a preparation method thereof. The capacitive screen can effectively prevent signal interference from the display module to the edge channel of the capacitive screen. [0004] Its technical scheme is as follows: [0005] The capacitive screen for preventi...
