摘要:
A display device substrate is provided with a transparent substrate, a frame portion, a first transparent resin layer, a black matrix and a second transparent resin layer. The frame portion is provided on the transparent substrate and formed in a frame region that surrounds a display region, containing carbon as a major colorant and having light shielding properties. The first transparent resin layer is formed on the transparent substrate in which the frame portion is formed. The black matrix is formed on the first transparent resin layer, dividing the display region into a plurality of openings having a matrix shape and containing an organic pigment as a major colorant. The second transparent resin layer is formed on the first transparent resin layer on which the black matrix is formed.

A light emitting diode (LED) package includes: an LED; a stack structure including a light-scattering structure spaced apart from the LED, and a light conversion layer disposed on at least one surface selected from an inner surface and an outer surface of the light-scattering structure and configured to convert light emitted from the LED into white light, wherein the light conversion layer includes a semiconductor nanocrystal; and an organic barrier layer disposed on a surface of the light conversion layer.
摘要:
A rear illuminated light guide for an LCD screen with in-coupling gratings to receive backlight from an input surface and to spread received backlight laterally within the light guide. Out-coupling gratings receive laterally spread backlight and output at least some of the received laterally spread backlight through an output surface that is opposite to the input surface and towards the LCD screen. The input and output gratings have lateral offset.
