technical field

The present application relates to the field of display technology, and in particular, to a flexible screen support mechanism and a rollable electronic device.

Background technique

The existing rollable electronic devices are mostly used in large-volume TV equipment. There are generally two solutions for the support mechanism of the flexible screen: one is to use a cross mechanism as the support mechanism for the flexible screen. When the flexible screen is pulled out of the reel , the cross mechanism on the back of the flexible screen is unfolded, which acts on the flexible screen. When the flexible screen is stored, the cross mechanism is closed, and the display screen is curled and stored; the other is to use a vertical chain as the support mechanism of the display screen. The curling direction of the display screen is vertical. When the flexible screen is pulled out of the reel, the vertical chains at the upper and lower ends of the flexible screen are pulled out at the same time. Since the rotation direction of the chain is perpendicular to the curling direction of the flexible screen, the chain can support the flexible screen. , When the flexible screen is stored, the flexible screen and the chain are respectively curled and stored, and the two are stored in different positions.

The above two flexible screen support mechanisms have large size and complex structure, and the flexible screen support mechanism and the display screen are arranged separately. When the flexible screen is curled, the flexible screen and the flexible screen support mechanism are respectively accommodated in different positions, resulting in the storage device. The size is large, so the existing solutions are not suitable for portable crimping equipment.
