Abstract

The embodiment of the present invention discloses a touch device, comprising: an elastic material layer, a photosensitive layer and a touch layer arranged in sequence in the light incident direction; the touch layer is provided with a key area of ​​the touch device; the elastic material layer At least one deformation structure is provided, and each deformation structure is used to deform part or all of the deformation units in the deformation structure when the corresponding position of the touch layer is pressed, so that the light irradiated on the photosensitive layer changes; the photosensitive layer , which is used to change the electrical signal at the position corresponding to the pressing operation when the light is sensed to change. The embodiment of the present invention solves the problems of complicated technical structure and high cost of the existing capacitive touch keyboard.

Description

technical field [0001] The present application relates to but not limited to the field of touch technology, especially a touch device. Background technique [0002] With the development and upgrading of electronic industry technology, the input devices of electronic products, such as the commonly used keyboard, also develop accordingly. At present, the mainstream keyboard on the market is the mechanical keyboard of the traditional desktop computer. This kind of mechanical keyboard adopts a rail-sliding structure. With the demand of market development, capacitive touch keyboards have been used as an upgrade of notebook keyboards. The capacitive touch keyboard is thinner and thinner overall, and the touch sensitivity will be higher. However, the mechanical keyboard has the disadvantages of bulkiness, high noise, easy wear, high failure rate and poor quality when inputting; the process structure of the capacitive touch keyboard Complicated and costly.
