1. Field
Embodiments of the present inventive concept relate to a display device capable of facilitating wiring processes between a light source module and a power supply configured to apply driving signals to the light source module.
2. Description of the Related Art
A liquid crystal display (LCD) device is a type of flat panel displays (FPDs), which is most widely used these days. An LCD device includes two substrates including electrodes formed thereon and a liquid crystal layer interposed therebetween. Upon applying voltage to two electrodes, liquid crystal molecules of the liquid crystal layer are rearranged, thereby adjusting an amount of transmitted light.
Such an LCD device may include a backlight unit. The backlight units may be categorized into a direct type, an edge type, a corner type, and the like according to a position of the light source.
In recent years, a light emitting diode (LED), which is characterized by low power consumption and high efficiency, is usually used as a light source of a backlight unit.
Further, a light source module including a plurality of LEDs mounted on a printed circuit board (PCB) may be used for the backlight unit.
The light source module may receive driving signals from an external power supply and may emit light. For this purpose, wires may be disposed between the light source module and the power supply to connect therebetween.
The direct-type backlight unit may include a large number of light source modules, and thus more wires may be disposed between the light source modules and the power supply.
In particular, a curved-type display device having such a direct-type backlight unit may include, compared to a general display device, more light source modules. This is mainly because the curved-type display devices are mostly provided in a quadrangular shape and curved along the longitudinal direction of a long side of the quadrangular shape, which is described below in detail.
That is, when the light source modules are arranged along the longitudinal direction of a short side of the curved-type display device, it is advantageous in that less light source modules are required. In this case, however, the light source modules may be curved, which incurs unstable operation of the light source modules. Accordingly, light source modules used for conventional curved-type display devices are arranged along the longitudinal direction of the long side of the display device. In such cases, the longitudinal direction of each light source module may correspond to the longitudinal direction of the short side which is not curved, such that the light source modules may not be curved. However, due to such structure, the conventional curved-type display device may require more light source modules. Accordingly, in the conventional curved-type display device, wirings between the light source modules and the power supply may become disadvantageously complicated.
