Samsung patents display panel with reflective walls to boost light output
Samsung has filed a patent for a display design that uses a reflective structure around tiny light-emitting pixels. The invention places a reflective metal layer under the pixels and reflective walls on the sides to bounce light back into the display, potentially making the screen brighter or more efficient.
In the filing’s own words
Provided is a display device including a driving substrate, a barrier layer disposed on an upper surface of the driving substrate and including a plurality of recesses, a micro-semiconductor light emitting device disposed in each of the plurality of recesses, and a side reflective structure disposed in the barrier layer and provided adjacent to a sidewall of each of the plurality of recesses.
What exactly they claim (claim 1)
1. A display device comprising: a driving substrate comprising a driving circuit; a barrier layer disposed on an upper surface of the driving substrate, the barrier layer comprising a recess; a micro-semiconductor light emitting device disposed in the recess; a lower reflective structure on a bottom surface of the recess, wherein the lower reflective structure comprises a reflective metal layer disposed on the driving substrate and an insulating layer disposed on the reflective metal layer, the insulating layer having a hydrophilic surface, and wherein a width of the reflective metal layer is greater than a width of the micro-semiconductor light emitting device such that the reflective metal layer faces an entire bottom surface of the micro-semiconductor light emitting device and extends continuously across the entire bottom surface of the micro-semiconductor light emitting device.
