Description

Bendable display device The present invention relates to a deformable display device, and more specifically, to a display device that changes position and is stored or withdrawn as needed. A vehicle is a device that drives in the direction desired by the user, and recently, it is equipped not only with an engine and wheels for driving but also with various devices for the user's safety and convenience. Vehicle convenience features are driven by development motives related to driver convenience, such as providing infotainment (information + entertainment) functions to the vehicle, supporting partial autonomous driving functions, or helping to secure the driver's visibility, such as night vision or blind spots. Examples include active cruise control (ACC), smart parking assist system (SPAS), night vision (NV), head-up display (HUD), around view monitor (AVM), and adaptive headlight system (AHS). In addition, vehicle safety features are technologies that ensure the safety of the driver and/or pedestrians, such as the lane departure warning system (LDWS), lane keeping assist system (LKAS), and autonomous emergency braking (AEB). Instrument clusters, which were used to provide information about the vehicle's status, are becoming digitized and are increasingly being replaced by display devices. Additionally, the center fascia, located between the driver and passenger seats, which previously only had output functions, now functions as an input device with the addition of touch capabilities. Displays not only output information but are also equipped with touch sensors to enable simultaneous touch input, allowing them to function as both output and input units; consequently, the size of display devices applied to vehicles is trending upwards. While increasing the size of the display panel for ease of use is desirable, it occupies a large area when not in use, and if it takes up too much space when turned off, it can detract from the vehicle's interior design. There is a need for a display device that can be pulled out only when necessary to provide a screen of sufficient size without compromising the vehicle's interior design elements.
