Touch induction substrate and touch device

Abstract

The invention provides a touch induction substrate and a touch device. The touch induction substrate comprises a bulge plate and an optical fiber net layer, wherein the bulge plate and the optical fiber net layer are overlapped in sequence, wherein the optical fiber net in the optical fiber net layer is mainly intertwined by a plurality of optical fibers arranged along a first direction and a plurality of optical fibers arranged along a second direction; the light entering end of each optical fiber in the optical fiber net is provided with a light emitter, and the light emitting end is provided with a light receiver; and the surface, which faces the optical fiber net layer, of the bulge plate is provided with a bulge corresponding to an optical fiber interaction in the optical fiber net. By use of the touch induction substrate and the touch device, through a principle that signal in the light receiver changes due to deformation when the optical fiber is pressed, a touch operation can be realized, and therefore, the touch induction substrate and the touch device can be suitable for manufacturing flexible display screens with a large size.

Description

technical field [0001] The invention relates to the technical field of touch sensing, in particular to an optical fiber-based touch sensing substrate and a touch device. Background technique [0002] With the development of display technology, flexible display screens (or flexible display panels) are gradually favored by people due to their thinness, deformability (such as bendable), and good mechanical properties, and the application fields of flexible display screens are also increasing. The more widely, for example, it is used to realize liquid crystal display, organic electroluminescent display, electronic paper, electrophoretic display, touch screen and so on. Since the flexible display screen is quite different from the traditional hard screen in terms of substrate materials, packaging materials, and overall multilayer light-emitting devices, the touch technology of the flexible display screen cannot simply copy the traditional method, that is, when the flexible displa...

Since the flexible display screen is quite different from the traditional hard screen in terms of substrate materials, packaging materials, and overall multilayer light-emitting devices, the touch technology of the flexible display screen cannot simply copy the traditional method, that is, when the flexible display screen When the display screen is used as a touch display screen, especially for a large-size display screen, it is difficult to realize click and touch operations on the flexible display screen due to its own flexible characteristics, thus limiting the flexibility of the flexible display screen. application
