Abstract
A reflective sheet with a dot-cut pattern for preventing both bright line and bright spot, and a method of manufacturing the same, is provided. The reflective sheet and method of manufacturing the same may be capable of reducing a manufacturing cost and also improving a manufacturing efficiency. The reflective sheet may include a bottom part including a hole for exposing a light source, the bottom part provided on a bottom surface of a cover bottom; a lateral part extending from the bottom part, the lateral part provided at a lateral surface of the cover bottom; a half-cut pattern formed in the boundary between the bottom part and the lateral part; and a plurality of dot-cut patterns formed at the lateral part.
Claims10
A reflective sheet, comprising:
- a bottom part including an array of holes each for exposing a respective light source, the bottom part provided on a bottom surface of a cover bottom;
- a lateral part extending from the bottom part, the lateral part provided at a lateral surface of the cover bottom;
- a half-cut pattern formed parallel to a row of holes of the array and extending along an entire length of the row at the boundary between the bottom part and the lateral part;
- and
- a plurality of dot-cut patterns formed at the lateral part, the dot-cut patterns having a dotted line shape parallel to the half-cut pattern with each dot-cut of the dot-cut patterns having an elongated shape defining a long axis parallel to the half-cut pattern,
- wherein the dot-cut patterns are composed of a plurality of groups, each group including a plurality of rows of dot cuts parallel to the half-cut pattern,
- wherein a first row of each group includes a plurality of dot-cuts having a dotted line shape such that a spacing between adjacent ones of the dot-cuts in the first row is less than a spacing between adjacent groups,
- wherein the number of the dot-cuts in the first row of each group is more than the number of the dot-cuts in a second row of each group, and
- wherein the plurality of dot-cut patterns are formed in a horizontal direction such that each group defines a triangular shape.
A display device, comprising:
- a liquid crystal panel provided with a plurality of pixels arranged in a matrix configuration;
- a backlight unit for supplying light to the liquid crystal panel;
- a cover bottom for receiving the backlight unit therein;
- and
- a driving circuit for driving the liquid crystal panel and a light source of the backlight unit,
- wherein the backlight unit includes a reflective sheet including a bottom part including an array of holes each for exposing a respective light source, the bottom part provided on a bottom surface of a cover bottom, a lateral part extending from the bottom part, the lateral part provided at a lateral surface of the cover bottom, a half-cut pattern formed parallel to a row of holes of the array and extending along an entire length of the row at the boundary between the bottom part and the lateral part, and a plurality of dot-cut patterns formed at the lateral part, the dot-cut patterns having a dotted line shape parallel to the half-cut pattern with each dot-cut of the dot-cut patterns having an elongated shape defining a long axis parallel to the half-cut pattern,
- wherein the dot-cut patterns are composed of a plurality of groups, each group including a plurality of rows of dot cuts parallel to the half-cut pattern,
- wherein a first row of each group includes a plurality of dot-cuts having a dotted line shape such that a spacing between adjacent ones of the dot-cuts in the first row is less than a spacing between adjacent groups,
- wherein the number of the dot-cuts in the first row of each group is more than the number of the dot-cuts in a second row of each group, and
- wherein the plurality of dot-cut patterns are formed in a horizontal direction such that each group defines a triangular shape.
