Abstract: Disclosed are a backlight module and a display device and method using the same, the backlight module comprises light-guide plate (302), an optical film (303) attaching to a side of a light emitting face of the light-guide plate (302), and a strip-like assembly (301) of point light source disposed at the side of the light incident face of the light-guide plate (302), the strip-like assembly (301) of point light source comprises point light sources toward the light incident face of the light-guide plate (302) thereon, an edge of one side of the optical film (303) corresponding to the light incident face of the light-guide plate (302) is provided with indents (303a).

Abstract: A backlight and a liquid crystal module having the same are provided. The backlight comprises: a light guide plate, a light-guide-plate fixing element for fixing the light guide plate, and at least one light source disposed adjacent to the light guide plate, wherein the light-guide-plate fixing element is made of thermal-contractive material. As the light-guide-plate fixing element is made of thermal-contractive material, in a test environment of high temperature and high humidity, it is possible to ensure that the light guide plate can expand and contract freely without resistance; meanwhile; while at normal temperatures, as the tight-guide-plate fixing element is in contact with the light guide plate without gap therebetween.

Abstract: The invention provides a surface light source device and an edge-lit type backlight module. The surface light source device comprises: a luminant, a bottom reflector plate, a light leaking plate and a plurality of side reflector plates, wherein the bottom reflector plate and the plurality of side reflector plates form a light guide box with an upper opening, the luminant is disposed on at least one of the plurality of side reflector plates, the light leaking plate is disposed in the upper opening of the light guide box, such that light from the luminant is transformed into an exiting surface light via the light leaking plate.

Abstract: A detect device and a detect method for transmittivity spectrum of the light guiding plate are provided. The detect device comprises a mixing cavity unit for providing a linear light source with continuous spectrum to a light guiding plate to be detected; a light guiding plate placing unit located at a side of the mixing cavity unit, on which the light guiding plate to be detected is disposed to receive light from the mixing cavity unit; and a detecting lens disposed above the light guiding plate placing unit for detect the spectrum.

Abstract: An electrode plate for an external electrode fluorescent lamp and a backlight are disclosed. The electrode plate for external electrode lamp comprising a strip pressure plate made of conductive material, wherein the strip pressure plate comprises a first surface on which at least one groove are provided and a second surface that is opposite to the first surface, the grooves run across both sides of the first surface and accommodate external electrodes of the external electrode lamps.

Abstract: Embodiments of the present invention disclose a backlight and a display device, to reduce the number of LEDs in a backlight, save costs, while avoiding dark areas appearing on the screen, so as to ensure display effect. The backlight comprises a first light guide plate and at least one light-emitting diode assembly, and the light-emitting diode assembly is located on one side of the first light guide plate. The light-emitting diode assembly comprises a second light guide plate, at least one light-emitting diode and a reflective film, wherein the at least one light-emitting diode is located on at least one side of the second light guide plate, and the reflective film is located on at least one side of the second light guide plate.

Abstract: The disclosed technology provides a backlight lamp guide, a back cover for a backlight, and a backlight. The backlight lamp guide, the back cover and the backlight comprise a lateral positioning mechanism. The lateral positioning mechanism prevents the backlight lamp guide and the back cover from moving with respect to each other in a direction parallel to the back cover.
