Light-emitting assembly, method for making same, and electronic device using same

A method for making a light-emitting assembly, comprising:

• providing a first substrate defining a light-transmitting area;
• forming a first reflective layer on a side of the first substrate, the first reflective layer defining an opening aligned with the light-transmitting area;
• forming a plurality of light emitters on a side of the first reflective layer away from the first substrate;
• forming a light guide layer covering the first reflective layer and the plurality of light emitters;
• and
• forming a second reflective layer on a side of the light guide layer away from the first substrate.

An electronic device, comprising:

• a main body, and
• a light-emitting assembly on the main body comprising:
• a first substrate defining a light-transmitting area, the first substrate having a first surface configured for receiving touches;
• a light guide layer on a side of the first substrate away from the first surface;
• a plurality of light emitters in the light guide layer, the plurality of light emitters being configured to project light to illuminate the light-transmitting area;
• a touch sensor facing the light-transmitting area and on a side of the first substrate away from the first surface;
• a first reflective layer between the first substrate and the light guide layer, the first reflective layer defining an opening aligned with the light-transmitting area;
• and
• a second reflective layer on a side of the light guide layer away from the first substrate.
