Abstract: A receiving container for a display apparatus receives a light-guiding unit and a light-generating unit disposed adjacent to a side surface of the light-guiding unit. The receiving container includes a bottom plate, a sidewall, and a gap-regulating portion. The light-guiding unit is disposed on the bottom plate. The sidewall faces the side surface of the light-guiding unit and is disposed at a peripheral portion of the bottom plate. The gap-regulating portion is formed at the sidewall or the bottom plate, to reduce a gap between the light-generating unit and the light-guiding unit. Thus, loss of light emitted by the point light source decreases so that power consumption of a backlight assembly and a display apparatus is reduced.

Abstract: An edge type backlight assembly for an LCD includes a plurality of flexible printed circuit boards, each of which has a group of one or more LEDs mounted thereon and disposed adjacent to each other. If one of the LEDs is defective, only the board on which the defective LED is mounted needs to be replaced, thereby simplifying rework of the backlight assembly and reducing its manufacturing cost. Further, by coupling separate sources of power to the separate LED mounting boards, the amount of light emitted by separate regions of the display can be independently controlled.

Abstract: In a two-way backlight assembly and a two-way LCD apparatus, the two-way backlight assembly provides light emitted from one light source to a first direction where a main LCD panel is placed and to a second direction where a sub LCD panel is placed. Also, a sub mold part for receiving the sub LCD panel comprises a black-colored material so as to prevent reflection of the light. Accordingly, thickness and power consumption of the backlight assembly may be reduced and display quality may be also improved by preventing leakage of the light at ends of the sub LCD panel.

Therefore, loss of the first and second light is reduced and light-using efficiency of the light-emitting module is increased. Furthermore, a power consumption of a display device is significantly reduced.
