Display device
View Patent ↗A display device 1 of an embodiment of the invention has a first display panel ( 10 A), a second display panel ( 10 B) that is disposed behind the first display panel ( 10 A), a front rim 20 that is disposed in front of the first display panel ( 10 A), an intermediate cases ( 30, 35 ) that are disposed between the first display panel ( 10 A) and the second display panel ( 10 B), and support the first display panel ( 10 A) and the second display panel ( 10 B), and a backlight 40 that is provided behind the second display panel ( 10 B). At least the front rim 20 , intermediate cases ( 30, 35 ) and backlight 40 are provided with fixing holes 23 a, 33 a, 38 a, 44 a in their corners, and fixing is effected integrally at each corner. Thanks to such structure, a display device is provided in which the distance between the two display panels can be altered by an inexpensive method.
1. A display device comprising:
a first display panel;
a second display panel disposed behind the first display panel;
a front rim disposed in front of the first display panel;
an intermediate case disposed between the first display panel and the second display panel, and supporting the first display panel and the second display panel; and
a backlight provided behind the second display panel;
at least the front rim, the intermediate case, and the backlight being provided with a fixing hole in each corner and being integrally fixed at each corner;
the front rim is formed in a picture-frame shape with sidewalls formed perpendicularly at the periphery thereof;
a rear cover is provided at a rear of the backlight, the rear cover comprising a rectangular plate body with sidewalls vertically provided from the periphery thereof;
long hollows provided in left and right sidewalls of the front rim and second hollows provided in left and right sidewalls of the rear cover contact against each other in a state in which the second hollows slide along the long hollows; and
the sidewalls of the rear cover are fixed to the side walls of the front rim so that a fixing position thereof is changeable.
