Abstract: The high intensity light output of edge lighting point light sources such as LEDs may generate undesired leakage light that is optically conducted by way of a continuum of the material of a components affixing adhesive member. In accordance with present disclosure, air filled grooves or other such discontinuities are formed in the adhesive member along respective light output pathways of the respective point light sources. One corresponding embodiment comprises spaced apart LEDs mounted on an FPCB; a light guide plate (LGP) disposed adjacent to the LEDs; a main support accommodating the LEDs and the LGP; and an adhesive member formed to affix together the FPCB, the main support, and the light guide, wherein the adhesive member is patterned to define air filled grooves along respective light output pathways of the LEDs.

Abstract: A backlight assembly is provided. The backlight assembly includes a light source, a light guide plate, a light collimation unit, and a guide groove. The light guide plate faces the light source in a first direction. The light guide plate includes a first surface on which light emitted from the light source is incident on and a second surface through which the incident light is emitted. The light collimation unit protrudes from an upper surface of the light guide plate and faces the light source. The guide groove is formed in a lower surface of the light guide plate along the first surface of the light guide plate.
