Non-contact type touch screen control device

Abstract

The invention provides a non-contact type touch screen control device, and belongs to the photoelectric field. The non-contact type touch screen control device is used for solving the problem that an existing non-contact type touch screen control scheme is complex in implementation and poor in reliability, and cannot conduct non-contact type operation on a far-distance large touch screen. The non-contact type touch screen control device comprises a handheld light-emitting device and a touch screen pasted film, the handheld light-emitting device provides light beams within a first appointed wavelength scope, and the touch screen pasted film is pasted to the surface of a touch capacitance screen to be controlled and sequentially comprises a first transparent protection layer, a multi-point isolating layer, a photoelectric induction layer and a second transparent protection layer in the direction from the surface of the touch capacitance screen to be controlled to the outer side. When the photoelectric induction layer is irradiated by the light beams within the first appointed wavelength scope, the irradiated part is broken down, and the broken-down irradiated part is in contact with the surface of the touch capacitance screen to be controlled through the multi-point isolating layer and the first transparent protection layer. The non-contact type touch screen control device is simple in structure, free of limitation of the touch screen size and the external environment and high in touch screen control reliability.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to a non-contact touch screen control device. Background technique [0002] In the past five years, smart phones have occupied the first place in the mobile communication terminal market. At the same time, in order to meet the diverse life and entertainment needs of consumers, various application software have emerged. While providing services, they also New requirements are put forward for the operation method of the mobile terminal, that is, the interaction between the user and the device. The traditional 12-key operation and the later full-keyboard equipment are far from being able to satisfy the operation functions provided by the various apps for users. At this time, the touch display technology emerges as the times require, and uses the simplest and most convenient way to enable consumers to complete operations. , to achieve an unprecedented human-computer interaction experienc...
