Problems solved by technology

[0003] However, in the process of generating plasma using a high voltage, the PDP emits electromagnetic waves and strong near-infrared rays, so the electromagnetic waves and strong near-infrared rays have adverse effects on human health or cause abnormal operations in electronic equipment
Color purity is also degraded by NIR, which results in degraded image quality

Embodiment Construction

[0016] In the following detailed description, when an element is referred to as being "on" another element, it can be directly on the other element or be indirectly on the other element with one or more intervening elements in between. . Also, when an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element with one or more intervening elements interposed therebetween. In the following, the same reference numerals refer to the same elements.

[0017] refer to figure 1 with image 3 , The optical filter according to one embodiment of the present invention includes: a support layer 10; and a strip-shaped photochromic pattern (photochromic pattern) 12, which is spaced apart on one surface of the support layer 10 and has light transmission properties, wherein the light transmission The rate can be changed according to the intensity of external light.

[0018] The supporting...

Abstract

An optical filter and a plasma display device having the same is provided. The optical filter includes a support layer. A photochromic pattern has pattern elements spaced apart on a surface of the support layer and has a light transmission characteristic wherein light transmission is changeable according to the intensity of external light.

Description

technical field [0001] The present invention relates to flat panel displays, and more particularly, to optical filters used in plasma display devices. Background technique [0002] A plasma display panel (PDP) is a flat panel display that displays characters or images by making phosphors emit light through plasma generated in a gas discharge. In recent years, a plasma display panel has emerged as a next-generation display device because it has natural color reproducibility, short driving time, and can be easily manufactured in a longer size and thinner level than a cathode ray tube (CRT) . [0003] However, the PDP emits electromagnetic waves and strong near-infrared rays in a process of generating plasma using a high voltage, and thus the electromagnetic waves and strong near-infrared rays have adverse effects on human health or cause abnormal operations in electronic equipment. Color purity is also deteriorated by near-infrared rays, which results in deteriorated image q...
