  • Patent number: 9101076
    Abstract: A flexible display device includes a display panel and a plurality of curving-restricting structures. The display panel has a display surface and a bottom surface opposite thereto. The display surface has a visible region and an outer region surrounding the visible region. The curving-restricting structures is disposed on at least one of the outer region of the display surface and the bottom surface of the display panel. Each curving-restricting structure has a top surface and at least a slanted side wall. The top surfaces of adjacent curving-restricting structures are spaced with each other, and the slanted side walls of adjacent curving-restricting structures face each other. When the flexible display device are curved to a predetermined extent, adjacent curving-restricting structures may resist against with each other to prevent the display panel from being unduly curved to be damaged, and thus a use reliability of the flexible display device is improved.

  • Patent number: 8924745
    Abstract: A power enabling circuit for uninterrupted power supplies includes a main power supply system, a backup power supply system and a power enabling control circuit. The main power supply system is electrically connected to an external power source to convert and output a conversion power, and generates a first power good signal when the conversion power is output normally. The backup power supply system outputs a backup power when the main power supply system cannot output the conversion power. The power enabling control circuit receives the first power good signal output from the main power supply system and simulates to generate a corresponding second power good signal, and also includes a normal power supply state in which the second power good signal is sent to a motherboard and a backup power supply state to receive the backup power and continuously output the second power good signal to the motherboard.
