Abstract
A backlight assembly includes a light guide plate, a light source module spaced apart by a gap from the guide plate, a receiving container and a gap adjusting element. The gap adjusting element is inter-coupled between the receiving container and the light source module and is actuatable to adjust the gap distance between the light source module and the light guide plate. Accordingly, a display quality may be prevented from being decreased, and the productivity may be enhanced.
Claims15
A backlight assembly comprising:
- a light guide plate comprising an incident surface into which a sourced external light is to be applied;
- a light source module comprising a plurality of light sources facing the incident surface of the light guide plate, the light source module being spaced apart from the incident surface by at least a first gap distance;
- a receiving container comprising a bottom surface and a sidewall extending from the bottom surface to form a receiving space, the receiving space receiving the light guide plate and the light source module;
- and
- a gap adjusting element operatively inter-coupled between the receiving container and the light source module, the inter-coupling being an adjustable one that can be actuated to adjust at least the spacing apart first gap distance between the light source module and the light guide plate, and
- wherein a combining groove is formed on the light source module and a combining hole is formed through the sidewall of the receiving container, and
- the gap adjusting element is operatively combined with the combining groove and the combining hole such that the gap adjusting element can differentially advance in at least one of the combining groove and the combining hole relative to advancement in the other when the gap adjusting element is turned in a pre-specified direction.
A backlight assembly comprising:
- a light guide plate comprising an incident surface into which a light is incident;
- a light source module comprising a plurality of light sources facing the incident surface of the light guide plate;
- a receiving container comprising a b face and a sidewall extending from the bottom surface to form a receiving space, the receiving space receiving the light guide plate and the light source module;
- and
- a combining element combined with the bottom surface of the receiving container and the light source module, the combining element being actuatable to adjust a position of the light source module along the bottom surface of the receiving container so as to thereby adjust a gap distance between the light source module and the light guide plate, and
- wherein a penetration line through which the combining element penetrates is formed through the bottom surface of the receiving container, and
- a combining groove into which the combining element is screwed is formed on a bottom surface of the light source module corresponding to the bottom surface of the receiving container, and
- wherein the penetration line has a bar-like shape extending along the first direction substantially parallel with the bottom surface of the receivinu container, so that the gap between the light source module and the light guide plate is adjusted according as the combining element moves along the penetration line combined with the light source module.
