摘要： A method of protecting an LED chip from damage by ESD and EMI when the LED chip is housed in a light-emitting diode(s) housing package (LED package) and the LED package is mounted on a printed circuit board is provided. The method comprises a step of not including an ESD and EMI suppressing Zener diode within the combination of the printed circuit board and the LED package and of providing within the combination of the printed circuit board and the LED package a first conductive member and a spaced apart second conductive member which are electrically connected to the LED chip and which have defined between them at least one insulative ESD and/or EMI suppressing region which breaks down in its insulative properties when subjected to voltages of absolute magnitudes greater than a predetermined threshold voltage.

摘要： A backlight unit for a display device includes: a light guide including a light incident surface; a substrate facing the light incident surface; a plurality of light sources on one surface of the substrate facing the light incident surface; and a first member disposed between the substrate and the light incident surface to space the light sources apart from the light guide. The first member includes: a support on one surface of the substrate that do not include the light source, the support having a first surface facing the light incident surface and a second surface facing the light sources; and a first layer disposed on the first surface and the second surface of the support to improve luminance uniformity across the light incident surface.

摘要： A reflection sheet and backlight unit including the same are disclosed. In one aspect, the reflection sheet includes a bottom surface, a plurality of side surfaces, each extending from the bottom surface and having an edge opposing the bottom surface, and a first cutting line formed in at least a first one of the side surfaces from a boundary between the first side surface and the bottom surface toward the opposing edge of the first side surface. The reflection sheet also includes a cover surface extending from the opposing edge of the first side surface, wherein the cover surface comprises a protruding surface protruding toward the first cutting line.
