Patent ID: 8339522

Claim:
A wide-screen liquid crystal television with at least 20-inch screen, in which there are formed, on boards, a tuner that receives a digital broadcast and outputs a digital video signal; an High-Definition Multimedia Interface (HDMI) terminal through which a digital audio and video signal is input and output; a rectifier circuit that rectifies an Alternative Current (AC) voltage inputted via an AC power cable to generate a Direct Current (DC) voltage; a power supply circuit that is supplied with a DC voltage from the rectifier circuit and generates various voltages; an analog circuit that performs analog processing on an input video signal and an input audio signal; a digital circuit that performs digital processing on a video signal input from one of the tuner and the HDMI terminal; an Low Voltage Differential Signaling (LVDS) terminal for outputting a liquid crystal panel driving signal for driving a liquid crystal panel via an LVDS cable from the digital circuit; an input and output circuit having an input and output terminal for inputting and outputting audio and video, connected to an external device; and an inverter circuit that is supplied with a DC voltage from the rectifier circuit and supplies an AC voltage to a backlight of the liquid crystal panel, the wide-screen liquid crystal television, including the liquid crystal panel that displays video on a screen in accordance with the panel driving signal and a cabinet that exposes the screen of the liquid crystal panel while housing the boards and the liquid crystal panel, with the boards disposed on the back of the liquid crystal panel, the wide-screen liquid crystal television, comprising: a first board on which the tuner, the HDMI terminal, and the LVDS terminal are disposed and the digital circuit is formed; a second board on which the input and output circuit is formed; a third board on which the analog circuit and the power supply circuit are formed; and a fourth board on which the rectifier circuit and the inverter circuit are formed; the first board, the second board, and the third board are identical to respective boards used in a plasma display panel, the fourth board is disposed in a vertically oriented position in the left, the third board is disposed in the lower center and the first board is disposed in the upper center adjacent to the third board while maintaining a position relationship between the third board and the first board when disposed on the back of the plasma display panel, the second board is disposed in the right, interposing the first board between the fourth board and the second board, and the cabinet is formed such that a center portion in a lateral direction projects backward, a terminal of the tuner and the HDMI terminal are exposed rightward from a right-side step portion formed by the projection, the input and output terminal is exposed in the upper right of the back of the cabinet, and the AC power cable is extended out from the lower left of the back of the cabinet.
