AI Technical Summary

Problems solved by technology

However, the use of optical film increases the overall thickness of the backlight unit, making it difficult for liquid crystal displays to be slim
In addition, it increases the manufacturing cost, thereby making the product less competitive
In addition, although the optical film is applied on the liquid crystal display, it cannot improve both the brightness and the viewing angle at the same time, in other words, only one of them can be improved.

Abstract

The present invention relates to an optical sheet and a composite sheet with a moire fringe and a backlight assembly having the same. The present invention provides an optical sheet including: a first pattern layer on which a first pattern array is formed and a second pattern layer on which a second pattern array generating a moire fringe by overlapping with the first pattern array is formed. With the present invention, it can expand a viewing angle while improving luminance. In addition, the number of LED light sources mounted on the backlight assembly is reduced, making it possible to reduce production costs.

Description

technical field [0001] The present invention relates to an optical sheet, a composite sheet and a backlight assembly comprising the same. More specifically, the present invention relates to an optical sheet and a composite sheet having moire stripes, and a backlight assembly including the same. Background technique [0002] Generally speaking, a liquid crystal display (LCD) is a device that displays graphics and images by injecting liquid crystal between two glass substrates formed by electrodes and applying an electric field to the liquid crystal, wherein the liquid crystal is an intermediate state between a liquid substance and a solid substance. Since a liquid crystal display is not a self-emitting device, it includes a backlight unit (BLU) as a light source for generating light. The liquid crystal display displays images while controlling the transmittance of light generated from a backlight unit in a panel unit in which liquid crystals are uniformly aligned. [0003] ...
