Liquid crystal display device

Abstract

The object of the present invention is to make parts and kinds of liquid crystal display devices in common for cope stably and flexibly with commercial products of computer makers and television makers which have been promoted in various kinds, for simplifying maintenance of a liquid crystal display unit mounted on computers, display monitors therefor or televisions, and preferably for enabling to omit positional adjustment of a light source unit and a liquid crystal display panel during the maintenance of the liquid crystal display device. For this object, the invention provides a liquid crystal display device comprising first, second, and third housings, a liquid crystal display panel fixed between the first and second housings, a light source (cold-cathode fluorescent tubes) fixed to the third housing, the second and third housings being detachable to one another, being constructed by overlapping the first, second and third housings with each other, wherein a timing-converter board fixed to an opposite side surface of the third housing to a side surface to which the light source is fixed, and protrusions formed on the opposite side surface so as to determine a maximum thickness of the liquid crystal display device.

1 . A liquid crystal display device comprising:
 a liquid crystal display panel;   a plurality of fluorescent tubes disposed Immediately below the liquid crystal display panel;   a housing disposed below the plurality of fluorescent tubes;   a light source control circuit mounted on the housing;   wherein a plurality of first terminals of the plurality of fluorescent tubes are electrically connected in parallel and connected to the light source control circuit by a cable, and each of a plurality of second terminals of the plurality of fluorescent tubes is connected to a separated lead,   wherein a plurality of connectors are connected to the light source control circuit, each of the plurality of connectors is connected to two of the separated leads, and   wherein the light source control circuit comprises a plurality of voltage transformation elements disposed along the plurality of high voltage terminals of the plurality of fluorescent tubes, and number of the plurality of voltage transformation elements and number of the plurality of fluorescent tubes are same.   
   
   
       2 . A liquid crystal display device according to  claim 1 , wherein a length of the cable is longer than a length of the separated leads. 
   
   
       3 . A liquid crystal display device according to  claim 1 , wherein the cable is extended to the light source control circuit across a surface of the housing. 
   
   
       4 . A liquid crystal display device according to  claim 1 , wherein lengths between each of the plurality of high voltage terminals and the plurality of voltage transformation elements are same. 
   
   
       5 . A liquid crystal display device according to  claim 1 , wherein the light source control circuit is disposed on a side of the housing opposite to a side where the plurality of fluorescent tubes are disposed.
