Touch sensing substrate and touch device

Abstract

The present invention provides a touch sensing substrate and a touch device. The touch sensing substrate includes protruding boards and optical fiber net layers stacked in sequence; the optical fiber net in the optical fiber net layer is mainly composed of a plurality of Optical fibers arranged in one direction and a plurality of optical fibers arranged in the second direction are interwoven, each optical fiber in the optical fiber network is provided with an optical transmitter at the light-incoming end, and an optical receiver at the light-emitting end; the convex Protrusions corresponding to the crossing points of the optical fibers in the optical fiber net are provided on the surface of the lifting plate facing the optical fiber net layer. The touch sensing substrate and the touch device of the present invention utilize the principle that the signal in the light receiver changes due to the deformation of the optical fiber when pressed, can realize touch operation, and can be applied to the manufacture of large-size flexible display screens.

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
