Abstract:
A light guide device and a liquid crystal display module and a liquid crystal display device having the light-guide device that can minimize the flowing of a light guide plate received in a mold frame by improving the structure of the light guide plate of the liquid crystal display device. A light guide device for receiving a light from a lamp unit and guiding the light to a display unit for displaying an image has a catching jaw is formed by cutting off both corner portion of a first end portion to which the light from the lamp unit is inputted. The width of the first end portion including the catching jaw is wider than the width of a second end portion opposite to the first end portion. Therefore, the catching amount of a catching boss integrally formed with the mold frame and the catching jaw of the light guide plate is remarkably increased and the light guide plate is prevented from being flowed towards the lamp even when exterior impacts are applied to the liquid crystal display device.
Abstract:
A lamp assembly, a backlight assembly and a LCD apparatus having the same are provided. The lamp assembly includes a lamp for emitting a light and a lamp holder for receiving one end of the lamp and for emitting a portion of the light emitted from the end of the lamp. The lamp holder has a transparent or semi-transparent material. The backlight assembly includes a light guiding plate for guiding the light emitted from the lamp and the lamp holder and for emitting the guided light and a receiving container for receiving the lamp assembly and the light guiding plate. Accordingly, the dark portion corresponding to the electrodes of the lamp may be reduced and brightness of the backlight assembly may be enhanced.

Abstract:
In the packaging of an LCD module within a small and lightweight case, the case comprising a front case and a rear case, a recess with a predetermined depth, formed at the edge of the bottom side of the LCD module, is combined with a boss formed at the case, and a recess with a predetermined depth, formed at the edge of its surface, is fastened to a fastening means for securing the LCD module, thereby minimizing the difference between the areas of the LCD module and the case and further reducing the number of processes required for combining the LCD module with the case. In addition, the recess formed at the surface edge of the LCD module is combined with a fastening hook formed at the rear case so that the LCD module can be secured to the rear case and to the front case without any separate fastening member such as a stud or insert.
Abstract:
A display module of an LCD device having a rear case shaped as a four-cornered container having sidewalls on each of its four edges; a backlight assembly formed by depositing and fixing a reflector plate, a light guide plate, and a series of sheets onto a mold frame where a lamp assembly receiving portion, a gate PCB receiving portion, and a source PCB receiving portion are integrally formed; an LCD panel module having an upper panel, a lower panel coupled to the upper panel with a liquid crystal inserted therebetween, a gate PCB electrically connected to an end portion of the lower panel, and a source PCB electrically connected to another end portion of the lower panel and has a conductive pattern for an electric signal to be applied to an inverter; a main chassis which defines an active screen area of the LCD panel module and couples the mold frame and the LCD panel module to the rear case; and a front case coupled to the main chassis and covering a whole surface of the LCD panel module excluding the active screen area.
