Abstract
The present invention provides a backlight unit. The backlight unit includes a light guide plate (LGP) having a incident surface and a plurality of light emitting diodes (LEDs) disposed adjacent to the incident surface. Each LED has an light-emitting axis, and the light-emitting axes are not parallel. The present invention further provides a liquid crystal display module including the backlight unit described above and a liquid crystal display panel disposed over the backlight unit. Moreover, the present invention provides an electronic device including the liquid crystal display module described above and a control circuitry electrically connected to the liquid crystal display module.
Claims13
A backlight unit, comprising:
- a light guide plate (LGP) having a first edge, a second edge, and a corner incident surface extending from the first edge to the second edge, in which the corner incident surface and extensions of the first edge and second edge define a space;
- and
- at least one light source having a diverging light output at a divergence angle incident at the corner incident surface, wherein the light source is positioned with respect to the corner incident surface such that the light source substantially resides within the space and the diverging light output covers an edge portion of the LGP.
Dependencies are inferred from the claim text.
