Abstract:
1. An LCD television comprising: a backlight including an inverter circuit and a fluorescent lamp; an LCD panel that displays a picture on a screen; speakers that output a voice; a main substrate that receives a television broadcast signal, causes a picture to be displayed on the LCD panel and a voice to be output via the speakers; and a plastic cabinet that houses the LCD panel, the speakers, and the main substrate, wherein the main substrate contains a primary power supply circuit, wherein the LCD panel has a wide type with 16:9 aspect ratio and a screen size of 20 or 30 inch and is constructed such that: a metallic frame is mounted on a front and sides of the LCD panel so as to surround its view area; a metallic shield panel is mounted on a rear of the LCD panel so as to cover the rear; and a vertically long inverter circuit is disposed on the rear along the narrow side of the LCD panel, the LCD television further comprising: a top fixing plate and a bottom fixing plate that are disposed in parallel to the top and bottom of the frame for the LCD panel, and that can be screwed and fixed to the top and bottom of the frame; a substrate fixing plate made of a mesh panel that is fixed at the upper side of the bottom fixing plate by horizontally offsetting so as to avoid the side where the inverter circuit is disposed and that is constructed such that the lower end is disposed so as to almost contact the bottom fixing plate, while the upper end is arranged at a height out of reach of the top fixing plate; an auxiliary substrate that is screwed on the rear of the substrate fixing plate to the side opposite to the side where the inverter circuit is disposed and that performs processing not implemented by the main substrate; a main substrate being supported along with the auxiliary substrate on the rear of the substrate fixing plate by being placed near the side where the inverter circuit is disposed, the main substrate supplying DC drive power to the inverter circuit by having the primary power supply disposed close to the side where the inverter circuit is disposed; and a bridge plate including the vertical length of the lower bridge support part is formed longer than the vertical length of the upper bridge support part, and the upper bridge support part having an oblong screw hole to allow the top fixing plate to be fixed to an upper fixing position and a lower fixing position; and the lower bridge support part has a screw hole formed that allows a stand bracket to be fixed, and wherein the cabinet being formed to cover most of the LCD panel so that the view area of the LCD panel is exposed toward the front and a pair of speakers are supported at the outward locations in width direction and below the bottom fixing plate; and wherein when the cabinet is fixed to the top fixing plate and bottom fixing plate, the bottom fixing plate has a screw boss at one location, and the top fixing plate has two screw boss at two locations that are mutually offset in width direction and vertical direction, and the top fixing plate also has two screw holes at locations that are offset in width direction.
