Liquid crystal display device
View Patent ↗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 first housing and a second housing;
a liquid crystal display panel and a light source disposed between the first housing and the second housing; and
a light source control circuit board fixed to an opposite side of the second housing to a side, wherein the light source is disposed on said a side, and a first voltage transformation elements disposed on the light source control circuit board,
wherein the second housing comprises a protrusion on the opposite side, that is higher than the first voltage transformation elements.
2. A liquid crystal display device according to claim 1 , wherein the protrusion determines a maximum thickness of the liquid crystal display device.
3. A liquid crystal display device according to claim 1 , wherein the protrusion is formed inside a peripheral edge of the liquid crystal display device.
4. A liquid crystal display device according to claim 3 , wherein the protrusion determines a maximum thickness of the liquid crystal display device.
5. A liquid crystal display device according to claim 1 , further comprising a timing-converter board fixed to the opposite side of the second housing.
6. A liquid crystal display device according to claim 5 , wherein the timing-converter board comprises a second voltage transformation element disposed on the timing-converter board.
7. A liquid crystal display device according to claim 6 , wherein the protrusion is higher than the second voltage transformation elements.
8. A liquid crystal display device according to claim 7 , wherein the protrusion determines a maximum thickness of the liquid crystal display device.
9. A liquid crystal display device according to claim 7 , wherein the protrusion is formed inside a peripheral edge of the liquid crystal display device.
