Abstract
The utility model provides a two-side liquid crystal display (LCD) device, which includes a first LCD panel, a second LCD panel, a backlight module disposed between the first and second LCD panels, and a circuit board for electronically connecting the two LCD panels. The display region of the first LCD panel is larger than that of the second LCD panel. A driving chip is disposed on the edge of the non-display region of the second LCD panel and used for driving the two LCD panels, so that it is not necessary to reserve a non-display region on the first LCD panel for the driving chip. In such arrangement, the effective display region of the first LCD panel is enlarged, and the entire size of the two-side LCD device is reduced, so that the two-side LCD device meets the light, thin and small size requirements.

But chip for driving 113 is arranged at host liquid crystal display panel 11 edge non-display areas in this double-sided liquid crystal display device 1, i.e. during these host liquid crystal display panel 11 designs, the zone that need reserve non-demonstration at its edge is used to be provided with chip for driving 113.This kind structural design has been compressed the area that second substrate 112 is used to show, so that has dwindled effective viewing area of this host liquid crystal display panel 11.
[utility model content]
Reserve the zone of non-demonstration at host liquid crystal display panel edge and be used to be provided with the problem that chip for driving increases the liquid crystal indicator overall dimensions in order to solve double-sided liquid crystal display device of the prior art, be necessary to provide a kind of effective viewing area that can enlarge the host liquid crystal display panel, reduce the double-sided liquid crystal display device of overall dimensions.
A kind of double-sided liquid crystal display device, it comprises one first display panels, one second display panels, one is arranged on the module backlight and the circuit board that electrically connects two display panels between this two display panels.Wherein, the viewing area of this first display panels is greater than the viewing area of this second display panels, and this second display panels edge non-display area is provided with the chip for driving that drives this two display panels.
Compared to prior art, the chip for driving of the utility model double-sided liquid crystal display device is arranged at the second display panels edge non-display area, makes first display panels needn't reserve non-display area this chip for driving is set.And industry is usually with the size of the whole double-sided liquid crystal display device of size design of the first bigger display panels of area, under identical effective viewing area condition, the utility model double-sided liquid crystal display device can enlarge effective viewing area of first display panels, reduce the overall dimensions of this device, thereby further satisfy compact demand.
