A backlight unit comprises a chassis having a bay, wall means defining the bay, an aperture opening to the bay, and an optical panel that includes at least one light management feature. The optical panel has one side forming a wall portion of the wall means. A light emitting structure is placed within the bay to light a two-dimensional area on the one side of the optical panel. The backlight unit also comprises a bracket for quick installation and removal of the light emitting structure through the aperture to and from the bay.

A housing for holding and fixing components of a liquid crystal display device is composed of a pair of frame members each having the same shape. Four sides of the side face of each frame member are formed such that an outer face section positioned at the outer side when combined and an inner face section positioned at the inner side when combined are stepped to each other, and a cut section is formed between the outer face section and the inner face section. The side face section of the frame member of the housing is formed to be stepped as described above, so that the strength and assembling property are enhanced, thereby being capable of preventing deterioration in display quality caused by the displacement of the position and space of the components.

Housing and display device provided with the housing

A backlight assembly comprises a plurality of linear light sources arranged in parallel behind a display screen. The plurality of linear light sources is divided into a first group and a second group. The linear light sources belonging to the first group are oriented in a first direction. The linear light sources belonging to the second group are oriented in a second direction opposite to the first direction. The backlight assembly comprises a first inverter substrate for driving the linear light sources belonging to the first group, and a second inverter substrate for driving the linear light sources belonging to the second group. The first and second substrates are arranged on one side of the linear light sources and the opposite side thereof, respectively.

Backlight assembly for directly backlighting displays

A liquid crystal display apparatus of a front light type includes a liquid crystal display panel, a light guide plate, a light source optically connected with the light guide plate and irradiating light to the light guide plate, a space holding member which supports and fixes the liquid crystal panel and the light guide plate in a region outside a display area of the liquid crystal display panel to have a predetermined gap. The space holding member having a base member and an adhesive material layer on at least one side of the base member. A refractive index of the adhesive material layer is smaller than that of the light guide plate.

A double-sided, direct-irradiation type backlight unit has a structure of capable of reducing the luminance irregularity and improve the luminance efficiency. The backlight unit has a scatter-reflection rod memberbetween each adjacent two of elongate lamps. The scatter-reflection rod memberhas a symmetric shape with respect to the line passing the center thereof in X-direction, and that passing the center thereof in Y-direction. The light emitted from the elongate lampin X-direction is reflected by the scatter-reflection-rod memberand then travels in the direction toward the front- and rear-side diffusion plates

A method is provided for manufacturing a support frame of a rectangular display panel within a short working time. The method includes a process of taking out L-shaped component members each having convex portions and concave portions arranged alternately at an end portion in a manner that each of the convex portions and concave portions is bilaterally symmetrical, while a shear droop and a burr are formed on an end portion and process of fitting and coupling end portions of L-shaped component members by placing the convex portions and the concave portions in such a manner that the shear droop of each of the convex portions faces the burr of each of the concave portions and the burr of each of the convex portions faces the shear droop of each of the concave portions and that that the convex portions and the concave portions are pushed towards each other and by pressing the convex portions and the concave portions using a pair of metal molds.
