Abstract: 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.

Abstract: 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 member 101 between each adjacent two of elongate lamps. The scatter-reflection rod member 101 has 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 lamp 102 in X-direction is reflected by the scatter-reflection-rod member 101 and then travels in the direction toward the front- and rear-side diffusion plates 106.

Abstract: 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.
