Description

Display device

[0001] The present disclosure relates to a display device comprising a display panel.

[0002] A display panel displays an input video signal as an image on an effective display surface. Depending on their characteristics, display panels are implemented in various configurations, such as liquid crystal panels and plasma panels, and are applied to various display devices.

[0003] Display panels can be classified into light-receiving panel structures and self-emissive panel structures depending on how light is generated to display images. Since a light-receiving panel structure may be a non-emissive structure that does not emit light on its own, a backlight may be required to generate light and supply it to the display panel. For example, a liquid crystal display panel may fall under the category of a light-receiving panel structure. A self-emissive panel structure may not require a separate backlight because the panel can emit light on its own. For example, an organic light-emitting diode (OLED) panel or LED signage may fall under the category of a self-emissive panel structure.

[0004] The display device may include a configuration for reinforcing strength. If the configuration for reinforcing strength includes a metal material, the weight of the display device may increase, and material costs and manufacturing costs may increase.

[0005] Provides a display device capable of reducing weight.

[0006] In addition, a display device capable of reducing damage caused by external impact is provided.

[0007] In addition, a display device with improved durability is provided.
