Abstract: A thin backlight module is disclosed. The backlight module includes a frame, a light guide plate, and a prism plate. The light guide plate is disposed in the frame, and has a first protrusion and a notch. The prism plate includes a second protrusion and an edge. The prism plate is laid on the light guide plate with the second protrusion and the edge of the prism plate abutting the first protrusion.

Abstract: A light guide for an LCD system has a light incident side, and is formed with a plurality of pattern structures. Each of the pattern structures has a pair of diagonally-disposed first points defining a first length therebetween, and a pair of diagonally-disposed second points defining a second length therebetween. The second length extends transverse to and crosses the first length. A ratio of the first length and the second length of one of the pattern structures adjacent to the light incident side is greater than a ratio of the first length and the second length of one of the pattern structures distant from the light incident side.

Abstract: A backlight unit. The backlight unit is employed in a display device having a main screen and a sub screen. The backlight unit comprises a first light-emitting unit and a second light-emitting unit. When the display device uses the sub screen, the first light-emitting unit provides a first light to the sub screen. When the display device uses the main screen, the first and the second light-emitting units respectively emit a second light and a third light, and a first aggregate light comprising the second light and the third light is provided to the main screen.

Abstract: A backlight assembly includes a frame configured to mount a liquid crystal panel, a light-guide plate and one or more light-emitting devices. The frame includes a plurality of conductive members embedded in the body of the frame and protruding into contact pads for connecting to the light-emitting device. The conductive members externally connect to a power source to supply electrical current to the light-emitting device.

Abstract: A method for assembling a component of a liquid crystal display device is introduced. An adhesion step is performed to adhere a flexible film to a substrate to form an assembled component by using an adhesion material covered over the overlapping area between the flexible film and the substrate. A plurality of air bubbles are trapped between the substrate and the flexible film by the adhesion material. To expel the air bubbles out of the assembled component, the assembled component is placed in an airtight chamber and a heating-pressurizing step is performed in the airtight chamber for properly raising the temperature of the assembled component and the air pressure within the airtight chamber.

Abstract: A display device that comprises a first viewing face allowing viewing of a first image on display from a first direction, a second viewing face allowing viewing of a second image on display from a second direction, a light source, a transparent substrate, a light guide plate receiving light provided by the light source, a surface of the light guide plate that transmits the light toward the first viewing face, and a plurality of reflective regions provided -over the transparent substrate that reflect the light transmitted from the surface toward the second viewing face.

Abstract: A liquid crystal display module. The liquid crystal display module includes a frame, a light guide plate, a diffuser, at least one prism, an LCD panel, a first power and signal circuit board, a second power and signal circuit board, a light emitting element and a reflector. The frame has a receiving portion and groove adjacent thereto. The light guide plate is disposed in the receiving portion. The diffuser is disposed on the light guide plate. The prism is disposed on the diffuser. The LCD panel is disposed on the prism. The first power and signal circuit board is connected to the LCD panel and has a first optical layer covering the groove. The is second power and signal circuit board is disposed in the groove. The light emitting element is disposed on the second power and signal circuit board and in the groove. The reflector is disposed under the frame.

Abstract: A thin backlight module. The backlight module includes a frame, a light guide plate, and a prism plate. The light guide plate is disposed in the frame, and has a first protrusion and a notch. The prism plate includes a second protrusion. The second protrusion is located in the notch so that the prism plate is positioned on the light guide plate.

Abstract: A method for assembling a component of a liquid crystal display device is introduced. Firstly, an adhesion step is performed to adhere a first part to a second part so as to form the component. Second, a heating-pressurizing step is performed in an airtight chamber for properly raising the temperature and the pressure of the airtight chamber to expel bubbles from the component.
