More Information
Summary:A display device and a method for removing noise due to a common voltage are provided to remove noise due to the common voltage in a mobile electronic device having an LCD panel. A display panel has a plurality of liquid crystal cells. A driving unit(120) outputs a first common voltage and a second common voltage, and outputs driving signals for driving the display panel. A first plate(30) supplies the first common voltage common electrodes for the liquid crystal cells. A second plate(110) is distanced from the first plate at a predetermined interval, and disposed along an outer conferential surface of the first plate. The second plate receives the second common voltage.
