Abstract

The invention provides a rollable display device and a driving method thereof. The rollable display device includes a flexible display panel. The first fixing part of the flexible display panel is located in the display area, and the second fixing part is located in the non-display area. The fixing part includes a heat-sensitive metal material, and the hardness of the fixing part changes with temperature; The storage part includes interconnected cavities and openings; in the first state, the flexible display panel is stored in the storage part; in the second state, at least part of the flexible display panel is deployed outside the storage part through the opening, and the flexible display panel is unfolded during : The first fixing part located outside the storage part starts to harden when it passes through the opening, and / or the second fixing part outside the storage part starts to harden when it passes through the opening. The embodiments of the present invention enable the rollable display device to be fixed during the unfolding process, ensuring that the flexible display panel pulled out of the storage portion can be completely flattened without curling due to rolling inertia.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a rollable display device and a driving method thereof. 【Background technique】 [0002] With the development of display technology, users not only pursue better visual experience such as high screen-to-body ratio, high resolution, and high contrast ratio when using electronic products. Moreover, the requirements for portability are getting higher and higher, so designs such as foldable display devices and rollable display devices have appeared in recent years. Among them, the display screen in the rollable display device can be switched between the curled and unfolded states, that is, the display screen of the display device is in the unfolded state when in use, and the display screen can be curled and stored to reduce its occupation when not in use. space. Since the display screen is usually made relatively thin, it is in a curled state before it is unfolded, so it ...
