Abstract

The invention discloses a touch display screen structure realized by an optical fiber, relates to a touch display screen, and is particularly applied to display fields which require high brightness, colorful display screens, touch display and the like. A single mode optical fiber, a multimode optical fiber, an optical fiber grating, a circulator, a wavelength division multiplexer, a multimode optical fiber used for feedback and a single mode optical fiber used for feedback form a pixel point; and N pixel points are arranged into a display screen structure. Optical signals are provided by a laser; and feedback optical signals are detected by a spectrometer. The wavelengths the optical signals at each pixel point are fixed; spectral components in the feedback optical signals are analyzed by the spectrometer; the positions of blocked points are judged so as to acquire the position of touch; therefore, the function of a touch screen is realized. The touch display screen structure realized by the optical fiber solves the problems that the cost is high, the brightness is low, images are easy to distort, the resolution is low, the touch response speed is slow, the anti-jamming capacity is poor and the mechanical strength is poor of the conventional display screen.

Description

technical field [0001] The invention relates to a touch display screen structure realized by optical fiber. It is especially used in display fields requiring high brightness, color display, and touch display. Background technique [0002] With the increasing number of multimedia information inquiries, people are talking about touch screens more and more, because touch screens are not only suitable for the national conditions of China's multimedia information inquiries, but also have many advantages such as durability, fast response, space saving, and easy communication. To distinguish touch screens from the technical principles, they can be divided into five basic types: vector pressure sensing technology touch screens, resistive technology touch screens, capacitive technology touch screens, infrared technology touch screens, and surface acoustic wave technology touch screens. Among them, the vector pressure sensing technology touch screen has withdrawn from the stage of hi...
