REGULAR PATTERN OPTICAL SHEET

摘要

The present invention relates to a regular pattern optical sheet, comprising: a transparent flat plate-shaped body; and a plurality of lens-shaped patterns regularly formed at one surface of the body, each having a same size of more than 0.1µm but smaller than 25 µm in diameter, wherein an angle formed by at least one line of lines straightly connecting each center of the plurality of lens-shaped patterns and a horizontal axis of an LCD pixel formed at an upper surface of the body is more than 5.5° but smaller than 9.5°, and a discrete distance between the plurality of lens-shaped patterns is more than 5% but smaller than 15% of a diameter of the lens-shaped pattern, whereby a high luminance characteristic can be accomplished over the conventional irregular lens pattern arrangement to the betterment of power consumption and environment friendliness. Furthermore, characteristic adjustment is enabled by regular pattern application capable of optical control to cater to various requirements of a user without occurrence of Moire pattern beating.
