Description

Double sided lighting display device {BOTH FACES LIGHTING DISPLAY DEVICE}

The present invention relates to a double-sided lighting display device, and more particularly to a double-sided lighting display device that allows information to be displayed on both sides.

In general, the liquid crystal display cannot emit light by itself, and thus displays an image by irradiating the liquid crystal panel of the liquid crystal display using a separate light source. Therefore, the liquid crystal display is provided with a backlight unit to irradiate light to the liquid crystal panel.

Here, the backlight unit is divided into an edge method and a direct method according to the installation position of the lamp, the edge method is a method in which the lamp is arranged on one side or both sides of the diffuser plate for guiding the light, and the direct method is directly below the diffuser plate. A plurality of lamps are arranged in the lamp to emit light toward the liquid crystal panel.

In addition, the backlight unit includes a liquid crystal panel installed in front of the bottom chassis, and a plurality of lamps and a plurality of sockets connected to the power inverter and the lamp while being fixed to the bottom chassis.
