Abstract
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.
