1. Field of the Invention
The present invention relates to a mobile terminal. More particularly, the present invention relates to a liquid crystal display (LCD) device of a mobile terminal and a driving method of the LCD device.
2. Description of the Related Art
A liquid crystal display (LCD) is a thin, flat display device comprising a plurality of color or monochrome pixels arrayed in front of a light source or reflector. An LCD device includes a LCD panel, driving circuit generating signals for driving the LCD panel, and a backlight assembly illuminating the LCD panel. Typically, such an LCD device is provided with a grounding structure for protecting the circuits from static electricity.
Slim, compact, and lightweight designs have become a mainstream for the market of mobile terminals.
However, the slim design of a mobile terminal presents difficulties in implementing the grounding structure for the LCD device.
In order to accommodate the slim designs of the mobile terminals, the grounding structure is also required to occupy a small space. This results in degradation of the electrostatic protection effect.
Also, the conventional grounding structure is implemented with an insulation tape. The adhesion of the insulation tape is time consuming and burdensome.
The degradation of the electrostatic protection causes variations of the level of the driving signal provided to the LCD panel and results in the transition of all the signal values to a uniform level which ultimately results in a white or black effect.
Accordingly, there is a need for an improved liquid crystal display device in a mobile terminal and driving method thereof that prevents the occurrences of a white or black effect.
