Abstract

display device. A display device includes a roll and a display module wound around the roll or unrolled from the roll. The display module includes: a display panel; and a plurality of supporters disposed at the rear of the display panel while extending in a horizontal direction and supporting the display panel. The height of each support is 0.1 to 0.6 times larger than the radius of the roller.

Description

technical field [0001] The present invention relates to display devices. Background technique [0002] As the information society develops, demands for various forms of display devices are increasing. In recent years, various display devices such as liquid crystal display devices (LCD), plasma display panels (PDP), electroluminescent displays (ELD), and vacuum fluorescent displays (VFD) have been used. [0003] A display device using an organic light emitting diode (OLED) is superior to a liquid crystal display (LCD) in luminance characteristics and viewing angle characteristics, and does not require a backlight unit, thereby realizing a thin display device. [0004] A part of the display can be bent or rolled around a roller, and a display device that is expandable or rollable can be realized by using a flexible display as needed. At this time, there is a problem that the flexible display is unsteadily wound up or unwound from the roll. [0005] current technology [0...
