US 6,307,530 B1 · LCD monitor having partitioned circuit section

Abstract

An LCD monitor having a partitioned circuit section is adapted to prevent a failure or malfunction caused by heat generated by the circuit section, and includes: an interface board receptive to video and sync signals generated by a computer; a main printed circuit board (PCB) for processing the video and sync signals received from the interface board, and for displaying the video signals on a liquid crystal panel; a power PCB for rectifying an AC into DC to supply a DC drive voltage to the main PCB and an audio PCB, the power PCB being disposed apart from the main PCB by a specified distance to prevent heat generated in the DC supply from causing a failure or malfunction of components in the main PCB; and an invertor PCB for converting the DC supplied by the power PCB to alternating current (AC), the power PCB separated from the main PCB being disposed on the side of an invertor section in the liquid crystal panel.

Dependent claims

A liquid crystal display (LCD) monitor operating with a computer and having a liquid crystal panel and a partitioned circuit section, comprising:

main printed circuit board (PCB) means for processing video and sync signals generated by the computer, and for displaying the video signals on said liquid crystal panel, said main PCB means defining a plane parallel to said liquid crystal panel;
interface board means disposed in the plane defined by said main PCB means and disposed on a first side of said main PCB means, said interface board means being connected to said main PCB means for providing the video and sync signals generated by said computer to said main PCB means;
and
power PCB means disposed on a second side of said main PCB means, opposite to said first side, and connected to said main PCB means for rectifying an alternating current (AC) into a direct current (DC) to supply a DC drive voltage to said main PCB means;
said LCD monitor further comprising invertor PCB means disposed in the plane defined by said main PCB means and on a side of said power PCB means remote from said main PCB means, said invertor PCB means being connected to said power PCB means for converting the DC supplied by said power PCB means into AC.
