Abstract
A light-emitting assembly with improved illumination includes a first substrate, a light guide layer, light emitters, a touch sensor, a first reflective layer, and a second reflective layer. The first substrate defines a light-transmitting area. The light emitters are in the light guide layer. The light emitters emit light to illuminate the light-transmitting area. The touch sensor is opposite to the light-transmitting area. The first reflective layer is between the first substrate and the light guide layer and defines an opening aligned with the light-transmitting area. The second reflective layer is on a side of the light guide layer away from the first substrate. An electronic device using the light-emitting assembly and a method for making the light-emitting assembly are also disclosed.
