For the LED backlighiting keypads, the graphic overlay lighted by the backside LEDs which assembled on the flex or rigid circuit layer. By this way, it is very simple and also economical. But it couldn't get a even lighting effect on surface. For this backlighting method, the LEDs can be assembled under centered buttons also can be assembled beside of the buttons or other areas. For the products need each button be backlighted, usually design the LEDs under the center of the buttons, then use the center holed metal domes and print transparent color on the graphic overlay.
