Abstract

A curved display device is provided including a display panel having a constant curvature and displaying an image, a backlight unit having the same curvature as that of the display panel, disposed at a rear surface of the display panel, and emitting light to the display panel, and a control unit locally controlling light emission of the backlight unit such that luminance of a light leakage region of the display panel is adjusted. Occurrence of light leakage in the curved display device is prevented, and thus, luminance of the curved display device is kept constant.

Description

technical field [0001] Embodiments of the present invention relate to a curved display device with improved image quality. Background technique [0002] A display device is a device that can display three-dimensional visual image information. [0003] Recently, flat panel display devices have been developed, which have relatively small weight and volume compared with cathode ray tubes, and thus have fewer limitations in installation and space, and exhibit excellent performance. Large-screen image displays that can be easily formed as flat panel displays and have high image quality and the like have been developed. [0004] Examples of flat panel display devices include liquid crystal display (LCD) devices, electroluminescence display (ELD) devices, field emission display (FED) devices, plasma display panels (PDP), thin film transistor liquid crystal display (TFT-LCD) devices, and flexible display device. [0005] Display devices may be classified according to installation...
