Abstract
An illuminated touch sensitive surface module and an illuminated device are disclosed. The illuminated touch sensitive surface module includes a cosmetic layer, a sensor, a controller and an illuminated device. The cosmetic layer permits light beams to pass through and objects to touch or hover thereon. The controller connects to the sensor and drives an illuminated mode of the illuminated device according to the position information. The illuminated device has many regions and at least one light guild film in which the light beams enter from the side and emit out of a top of individual light guide film. Further, each light guide film has a bottom on which micro members are formed for changing path of the entering light beams and block members for defining the regions. In the illuminated mode, the touched or hovered regions of the illuminated device are illuminated while the other regions are dark. Thus, the illuminated touch sensitive surface module provides the regional illumination in response to a gesture operation.
