Technical Field
The present invention relates generally to display devices, and more particularly, to a rollable display screen for a display device.
Background
With the rapid development of electronic technology, various display devices such as televisions are used.
Recently, efforts have been made to develop a large screen television having a Liquid Crystal Display (LCD) or a Light Emitting Diode (LED) display screen. While many large screen televisions are used in residential or private environments, large screen televisions also have a range of business related applications (office halls or waiting areas, meeting spaces, reception areas, restaurants, bars or retail companies, etc.). Most current display devices are rigid fixed structures.
Accordingly, the display screen size of such display devices is not adjustable, and thus they may not be suitable for certain applications and situations.
Meanwhile, research on flexible display screen (soft screen) technology is also advancing and deepening. Such a flexible display may be bent, folded or rolled up without damaging the flexible display.
