A receiving container for a display device includes a bottom plate, a sidewall and a grounding unit. The sidewall is extended from the bottom plate to define a receiving space. The grounding unit is integrally formed with the bottom plate. The grounding unit includes a grounding member that grounds a circuit board received in the receiving space. The circuit board includes a grounding electrode and the grounding member corresponds to the grounding electrode. The grounding member is formed on a rear surface of the bottom plate. The grounding member may include a protrusion or a projected portion having an elastic structure.

Display device

An electronic device includes a central processing unit ('CPU'), first and second display panels, and first and second display panel drivers. The CPU provides an image signal and an input control signal. The first and second display panels respectively display images. The first and second display panel drivers drive the first and second display panels according to the image signal and the input control signal. The CPU includes an interface transmission unit outputting an interface signal to control the first and second display panel drivers. The first and second display panel drivers respectively include first and second interface receiving units receiving the interface signal from the interface transmission unit. The interface signal includes a display panel selection bit and a data bit.

Display device, electronic device having the same, and method thereof

A flat panel display device includes a display module, a protection window member and a layer disposed in an area between the protection window member and a display area of the display module. The protection window member includes a stepped portion within which the layer is disposed. The stepped portion may include a recess or a plurality of layers.

A gray voltage generation circuit for driving a liquid crystal display rapidly outputs an altered gray voltage so that a source driving circuit can charge liquid crystal capacitors constructed in a liquid crystal panel in a short period of time. In response to the gray voltages from the gray voltage generation circuit, while driving a positive polarity, the source driving circuit generates a liquid crystal driving voltage of higher level than the existing liquid crystal driving voltage when applying a gate clock signal of high level, and generates a liquid crystal driving voltage of a level similar to the existing liquid crystal driving voltage when applying a gate clock signal of low level. And, while driving a negative polarity, the source driving circuit generates a liquid crystal driving voltage of lower level than an existing liquid crystal driving voltage when applying a gate clock signal of high level, and generates a liquid crystal driving voltage of a level similar to the existing liquid crystal driving voltage when applying a gate clock signal of low level.
