US Patent 11839036 Flexible display device

A flexible display device is provided. The flexible display device includes a first housing, a second housing, a rolling mechanism, a flexible display screen, and a support plate mechanism. The flexible display screen can be retracted or expanded relative to the rolling mechanism. When the flexible display screen is completely expanded, a second support surface of a support plate and a first support surface of the second housing support the flexible display screen with their whole surfaces, thereby preventing the flexible display screen from collapsing and deforming.
