Description

Carrying device and display

The present invention relates to a carrier device and a display, and more particularly to a carrier device adapted to carry a flexible substrate and a display employing the above-described carrier device.

With the advancement of display technology, displays have been trending toward thinning, planarization, and miniaturization, while also reducing weight and reducing the space occupied. In recent years, flexible displays have been gradually evolving because they can be less space-consuming via curling, so that they are portable. In addition, when the flexible display is used, it can be spread out from the curled state and become a flat state, so that the display screen produced by the flexible display can have a large area, thereby increasing the application level of the display.

However, in the conventional flexible display, when the flexible display is to be used for spreading, the bent portion of the panel tends to be warped and not flat on the carrier. That is to say, when the flexible display is not bent, the bending region of the panel may not be fixed and cannot be completely flattened on the carrier board, thereby causing the brightness of the flexible display to be uneven and tolerant. The impact ability is reduced.

The present invention provides a carrier device that allows the flexible substrate to be completely flat against the carrier plate when not bent.
