DESCRIPTION OF RELATED ART

Liquid crystal display (LCD) device and organic light-emitting diode (OLED) display device are two types of rapid development of display devices.

The LCD display device has several advantages of body slim, electricity-saving and radiation free, etc. and thus has been widely used. Such as LCD TVs, mobile phones, personal digital assistants (PDA), digital cameras, desktop or laptop computer screens, and so on.

The OLED display device has a self-emissive characteristic and uses extremely thin organic material coatings and glass substrates. The organic materials would emit light when a current pass therethrough and thereby achieving display function.

In recent years, with the development of display technology, various manufactures have launched curved display devices such as curved TVs. Generally, the curved display device can provide better viewing experience from the center to the edge of screen while the traditional flat display device always has an unsatisfactory display effect at the edge of screen. The curved display device has a curve design for its whole screen and can provide a wide panoramic image effect. Regardless of the screen center or edges are able to bring the same visual enjoyment, and the off-axis viewing distortion in the situation of close viewing can be reduced. Moreover, the curved display device can stretch the user's viewing distance to thereby achieve a better viewing experience. Compared with the traditional flat display device, the curved display device has the following advantages of: (1) product differentiation; (2) wider viewing angle; and (3) reduced distortion of close viewing. Accordingly, the curved display device can provide a wider viewing angle and a wider panoramic image than the traditional flat display device, letting the whole sense of reality of image more strongly.

Nowadays, the LCD display device and OLED display device both can be made into curved display devices. However, the curvature of display screen is fixed and a structure of the base for mounting the display screen also is fixed.FIG. 1is a schematic view of a conventional display device. The conventional display device includes a base100and a curvature-constant display screen300mounted on the base100. The base100includes a placing part110and two mounting parts130upwardly extending from two ends of the placing part110. The placing part110of the base100is a single member and thus its structure is fixed and unchanged. If the conventional base100is used for mounting a curvature-adjustable display screen, the structure of the base100is fixed and thus could not change along with the change of curvature of the display screen, which hinders the change of curvature of the display screen, so that the curvature of display screen could not be adjusted according to the viewing needs of user, the display effect wanted by the user could not be achieved consequently.
