Embodiment Construction

[0037] image 3 It is a schematic diagram of the back side of the plasma TV set with the protective plate structure of the present invention.

[0038] As seen in the same drawing, the plasma television set of the present invention is composed of a plasma display assembly 10; in order to install the casing 20 of the above-mentioned plasma display assembly 10; being installed on the lower end of the above-mentioned casing 20 to form the vacuum of the front display window A fluorescent display 30; a protective plate 40 connected to the back of the vacuum fluorescent display.

[0039] A plasma display assembly 10 and various printed circuit boards are installed inside the casing 20 to cooperate with the rear cover (not shown) on the back side.

[0040] In addition, the above-mentioned vacuum fluorescent display 30 is a display device based on the principle that electrons collide with fluorescent substances in a vacuum state to emit light, and the left and right ends of the vacuum...

Abstract

This invention relates to a plasma TV, especially to an electromagnetic wave shielding structure that can connect the electric guard board to the background of the vacuum luminescence display to shield the electromagnetic wave. And this invention is composed of the internally-arranged tuner with the TV capability and the plasma display device installed the VFD-vacuum luminescence display for constructing the front display window, wherein at the back of the vacuum luminescence display, the external face that covers the vacuum luminescence display can connect with the guard board of the contacting part, wherein the guard board is used to connect with the back cover, case, supporting board or filter, so the electromagnetic wave produced from the device won't leak out through being conducted to the back cover and case.

Description

technical field [0001] The present invention relates to a plasma TV, especially an electromagnetic wave shielding structure of a display device which connects a conductive protective plate to the back of a vacuum fluorescent display to shield electromagnetic waves generated by the device. Background technique [0002] Generally speaking, PDP (Plasma display panel)—that is, plasma display is applied as a large-screen thin-walled display device. Due to its complex circuit problems and other reasons, it is mainly developed with an external monitor without a tuner. of. [0003] However, with the continuous development of technology, plasma TVs with built-in tuners have been formally developed / produced, and in order to meet the needs of digital TV broadcasting, plasma TVs with built-in tuners have been developed. [0004] This is the development of plasma TVs, which began to be converted from industrial use to home use, so there is a trend of continuous improvement in design and...
