A lighting touchpad includes a circuit board and a light-emitting element. The circuit board has a touch sensing area, and a plurality of first sensor cells and at least one second sensor cell are formed in the touch sensing area. Each of the first sensor cells has the same first areas, and each of the at least one second sensor cell has a second area smaller than the first area. The light-emitting element is disposed in the touch sensing area and adjacent to the at least one second sensor cell. The configuration of the present invention is helpful to reduce a touch dead zone (also be called an inactive area) of the lighting touchpad.

A capacitive touch device capable of distinguishing conductor and nonconductor includes a flexible sensor layer receiving a first driving signal, an elastic insulation layer below the flexible sensor layer, and an electrically conductive layer below the elastic insulation layer and receiving a second driving signal synchronous but out of phase to the first driving signal. The flexible sensor layer generates a capacitance variation responsive to an object touching thereon, for identifying the object as a conductor or a nonconductor.

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.
