Title:
OPTICAL FILM FOR MINI LED OR MICRO LED BACKLIGHT UNIT
Document Type and Number:
WIPO Patent Application WO/2020/166864
Kind Code:
A1
Abstract:
Disclosed is an optical film for transmitting light emitted from a mini light emitting diode (LED) or micro LED. An optical film may include a first base film and a reflective layer disposed at one side of the first base film so as to reflect a part of the light emitted from the mini LED or the micro LED. Here, the reflective layer may include a plurality of holes configured to transmit another part of the light emitted from the mini LED or the micro LED. In this case, as the position of at least one of the plurality of holes is closer to the position on the reflective layer corresponding to the center of the mini LED or the center of the micro LED, the diameter of the at least one of the plurality of holes may be smaller.
