Disclosed is a backlighting device for a dual LCD (Liquid Crystal Display). The backlighting device includes a circuit board with a through hole; a backlighting illumination device situated within the hole for radiating light in a first direction substantially perpendicular to a first face of the circuit board and in a second direction substantially perpendicular to a second face of the circuit board; a main LCD being situated on one face of the backlighting illumination device in the first direction, for displaying first information in the first direction; and a slave LCD being situated on another face of the backlighting illumination device through the through hole in the second direction, for displaying second information in the second direction.
An illuminating device is provided for use as a backlight of a liquid crystal display, and has a plurality of light sources and a light guiding plate emitting lights from the light sources outward. At least one of the light sources is configured to be lighted independently from the rest of the light sources. This illuminating device is applied to equipment such as a two surface display type cellular phone and is disposed between a main panel and a sub-panel to illuminate both panels. All light sources may be used to illuminate the main panel when the main panel is used, and some of the light sources may be used to illuminate only an area of the sub-panel when the sub-panel is used so that effective illumination may be implemented. Accordingly, light sources need not to be unnecessarily lighted when the sub-panel is used, which leads to low power consumption.
A display device is provided which offers double-sided display and achieves a thin structure and also which prevents deterioration in display quality of each of front and back display units when an illumination unit such as a backlight is shared by these display units. The display device includes a first display unit having a display surface on the front surface thereof; a second display unit having a display surface on the rear surface thereof; and a common illumination unit interposed between the first display unit and the second display unit, for illuminating both the first display unit and the second display unit with light. The illumination unit includes a light-guiding member having a first light-emitting surface opposed to the first display unit and a second light-emitting surface opposed to the second display unit, and a transflector is interposed between the second light-emitting surface of the light-guiding member and the second display unit.
An electronic display includes a first display, a second display and an enclosure that is adapted to house the first display and the second display such that the back side of the first display faces the back side of the second display. The enclosure includes a first side wall, a second side wall, and a perimeter wall. At least one support circuit disposed between the back side of the first display and the back side of the second display is operatively coupled to each of the first display and the second display. The thickness of the enclosure is substantially defined by a thickness of the first side wall, the thickness of the first display, the thickness of the second display, the thickness of the support circuit, and a thickness of the second side wall when the first display, the second display, and the support circuit are housed in the enclosure.
An electro-optical device includes an electro-optical panel which displays an image on a display surface; a supporting member which supports the electro-optical device; and a flexible wiring substrate which is connected to the electro-optical device. The wiring substrate is bent such that at least a portion of a surface of the wiring substrate is opposite to a side surface of the supporting member, in regions other than a side of the wiring substrate connected to the electro-optical panel.
