Embodiment Construction

[0055] Reference will now be made in detail to the preferred embodiments of the invention, examples illustrated in the accompanying drawings. Where possible, the same reference numerals will be used throughout the drawings to refer to the same or like parts.

[0056] Figure 8 is a view illustrating a pre-filter of the plasma display apparatus according to the first embodiment of the present invention.

[0057] refer to Figure 8 , the front filter 130 includes: an anti-reflection coating 150 , an optical characteristic film 152 , a touch screen 156 , and a near infrared (hereinafter referred to as “NIR”) shielding film 158 . Here, it is desirable that the front filter 130 is a film type filter without glass for support.

[0058] An adhesive layer is formed between the respective films 150, 152, 156 and 158 of the front filter 130 to adhere the respective films 150, 152, 156 and 158 to each other. Usually, specific substances are added to the adhesive layer to form the opt...

Abstract

The present invention relates to a front filter having a touch screen, and a plasma display apparatus having the same. The front filter installed on a front surface of a panel of a plasma display apparatus, the front filter including: a touch screen for generating a coordinate signal with respect to a touch point.

Description

technical field [0001] The present invention relates to a plasma display device, in particular to a front filter with a touch screen and a plasma display device with the filter. Background technique [0002] A plasma display panel (hereinafter referred to as "PDP") generally displays images including characters or graphics, which is achieved by emitting light from fluorescent substances using ultraviolet light having a wavelength of 147nm, in an inert gas mixture such as He+Xe, Ne+Xe, Ultraviolet rays are generated during gas discharge of He+Ne+Xe, etc. Such a PDP has characteristics of easy thinning and large size, and greatly improves image quality thanks to the development of modern technology. In particular, three-electrode alternating current (AC) surface discharge type PDPs have advantages of low voltage operation and long lifespan because wall charges stored on the surface during discharge protect electrodes from sputtering generated by discharge.
