A backlight assembly includes a receiving container, a light-generating unit and a reflective sheet. The receiving container includes a bottom plate and a sidewall. The sidewall extends upwardly from an edge portion of the bottom plate to form a receiving space. The light-generating unit includes a light-emitting substrate disposed in the receiving space, light-emitting diodes (LEDs) and a driving circuit. The light-emitting substrate includes a light-emitting region and a peripheral region. The LEDs are disposed in the light-emitting region. The driving circuit disposed in the peripheral region controls the LEDs. The reflective sheet includes a center portion and a cover portion. The center portion is disposed on the light-emitting region. The cover portion is disposed on the peripheral region to cover the driving circuit.
This application claims priority under 35 U.S.C. §119 to Korean Patent Application No. 2008-52961, filed on Jun. 5, 2008 in the Korean Intellectual Property Office (KIPO), the disclosure of which is incorporated by reference in its entirety herein.
An exemplary embodiment of the present invention includes a backlight assembly. The backlight assembly includes a receiving container, a light-generating unit and a reflective sheet. The receiving container includes a bottom plate and a sidewall upwardly extending from an edge portion of the bottom plate to form a receiving space. The light-generating unit includes a light-emitting substrate, a plurality of light-emitting diodes (LEDs) and a driving circuit. The light-emitting substrate may be disposed in the receiving space and include a light-emitting region and a peripheral region disposed outside of the light-emitting region. The light-emitting region may be disposed on an upper surface of the light-emitting substrate. The LEDs may be disposed in the light-emitting region. The driving circuit may be disposed in the peripheral region and control the LEDs. The reflective sheet includes a center portion and a peripheral region. The center portion may be disposed on the light-emitting region and include a plurality of holes through which the LEDs respectively pass. The cover portion may be disposed on the peripheral region to cover the driving circuit. The cover portion may be attached to the sidewall.
The embodiments of the present invention will become more readily apparent by reference to the following detailed description when considered in conjunction with the accompanying drawings wherein:
The present invention is described more fully hereinafter with reference to the accompanying drawings, in which exemplary embodiments of the present invention are shown. The present invention may, however, be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein. It will be understood that when an element or layer is referred to as being “on,” “connected to” or “coupled to” another element or layer, it can be directly on, connected or coupled to the other element or layer or intervening elements or layers may be present. Like numerals may refer to like elements throughout. Hereinafter, exemplary embodiments of the present invention will be explained in detail with reference to the accompanying drawings.
At least one sidewall of the first to fourth sidewalls 322, 324, 326, and 328 may have a cross-section of a substantially ‘L’ shape and the remaining sidewalls of the first to fourth sidewalls 322, 324, 326, and 328 may have a cross-section of a substantially ‘U’ shape. For example, as illustrated in FIGS. 4 and 5, the first and second sidewalls 322 and 324 may have the cross-section of the substantially ‘L’ shape, and the third and fourth sidewalls 326 and 328 may have the cross-section of the substantially ‘U’ shape.
The first sidewall 322 having the cross-section of the substantially ‘L’ shape may include a first side part 322 a and a first upper part 322 b. The first side part 322 a may upwardly extend from the first edge of the bottom plate 310. The first upper part 322 b may inwardly extend from an upper edge of the first side part 322 a with respect to the receiving space.
The second sidewall 324 having the cross-section of the substantially ‘L’ shape may include a second side part 324 a and a second upper part 324 b. The second side part 324 a may upwardly extend from the second edge of the bottom plate 310. The second upper part 324 b may inwardly extend from an upper edge of the second side part 324 a with respect to the receiving space.
The first and second sidewalls 322 and 324 may extend in the first direction DI1 and be opposite to each other. The third and fourth sidewalls 326 and 328 may extend in the second direction DI2 and be opposite to each other. At least one of the first to fourth sidewalls 322, 324, 326, and 328 may have a cross-section of a substantially straight line shape. For example, the first and second sidewalls 322 and 324 may have the cross-section of the substantially straight line shape and the third and fourth sidewalls 326 and 328 may have the cross-section of the substantially ‘U’ shape. For example, alternatively, the first to fourth sidewalls 322, 324, 326, and 328 may have the cross-section of the substantially straight line shape.
At least one of the first to fourth sidewalls 322, 324, 326, and 328 may have a cross-section of a substantially ‘L’ shape or a substantially ‘U’ shape. For example, the first to fourth sidewalls 322, 324, 326, and 328 may have the cross-section of the substantially ‘L’ shape.
The first sidewall 322 having the cross-section of the substantially ‘L’ shape may include a first side part 322 a and a first upper part 322 b. The first side part 322 a may upwardly extend from the first edge of the bottom plate 310. The first upper part 322 b may outwardly extend from an upper edge of the first side part 322 a with respect to the receiving space.
The second sidewall 324 having the cross-section of the substantially ‘L’ shape may include a second side part 324 a and a second upper part 324 b. The second side part 324 a may upwardly extend from the second edge of the bottom plate 310. The second upper part 324 b may outwardly extend from an upper edge of the second side part 324 a with respect to the receiving space.
The third sidewall 326 having the cross-section of the substantially ‘L’ shape may include a third side part (not illustrated) and a third upper part (not illustrated). The third side part may upwardly extend from the third edge of the bottom plate 310. The third upper part may outwardly extend from an upper edge of the third side part with respect to the receiving space.
The fourth sidewall 328 having the cross-section of the substantially ‘L’ shape may include a fourth side part (not illustrated) and a third upper part (not illustrated). The fourth side part may upwardly extend from the third edge of the bottom plate 310. The fourth upper part may outwardly extend from an upper edge of the fourth side part with respect to the receiving space.
