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 liquid crystal display panel comprising a pair of longer sides, a first shorter side, and a second shorter side;
a first housing comprising a liquid crystal display window;
a second housing comprising a first surface and a second surface opposed to the first surface;
a plurality of light sources disposed immediately below the liquid crystal display panel, and disposed on the first surface of the second housing; and
a circuit board comprising a light source control circuit mounted on the second surface of the second housing;
wherein the plurality of light sources are connected to the circuit board via lead,
wherein the circuit board comprises a plurality of circuit, and
wherein the liquid crystal display panel is fixed between the first housing and the second housing, and the second housing comprises a plurality of protrusions on the second surface that is higher than the plurality of circuit elements, the circuit board being arranged between the plurality of protrusions.
2. A liquid crystal display device according to claim 1 , wherein the plurality of circuit elements are voltage transformation circuits mounted on the circuit board.
