Abstract

The present invention discloses an LCD device. The LCD device includes a bezel, a light guide plate on the light source for guiding light, an optical film on the light guide plate for processing the guided light through the light guide plate, an LCD panel directly carried on the optical film, a driving chip, a FPC with metal wires, wherein the driving chip bonds with the FPC and is used for being coupled to the LCD panel via the metal wires of the FPC, and a heat sink attached between the bezel and the FPC and used for dissipating heat generated from the driving chip.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a liquid crystal display (LCD) device, more particularly, to an LCD device capable of omitting a housing.[0003]2. Description of the Prior Art[0004]LCDs are widely used in modern information equipments such as computers, cell phones, personal digital assistances (PDAs), etc, due to their thin, lightweight, low power consumption features. Generally, an LCD comprises a liquid crystal panel and a backlight module. Since the liquid crystal panel itself does not light, the LCD requires light sources which emit light from the backlight module. Light emitted by the backlight modules passes through liquid crystals in the liquid crystal panel. The intensity of light which would be conveyed to a viewer is adjusted by means of an alignment of the liquid crystals. Subsequently, images are produced.[0005]According to the location of light sources, the backlight module of the LCD device is classified ...
