  • Patent number: 12044458
    Abstract: A cabinet with anti-condensation mechanism is used to control opening and closing a cabinet door of the cabinet. The cabinet includes a control module, a temperature control module, and a locking module. The control module senses a cabinet-inside temperature inside the cabinet, and senses cabinet-outside temperature and a cabinet-outside humidity outside the cabinet to generate a dew-point threshold value. The temperature control module is used to adjust the cabinet-inside temperature. The locking module is used to lock the cabinet door or unlock the cabinet door. The control module controls the locking module according to the cabinet-inside temperature and the dew-point threshold value, and controls the temperature control module to adjust the cabinet-inside temperature to be greater than or equal to the dew-point threshold value when the control module receives a trigger signal.

  • Patent number: 11244597
    Abstract: A display device and a driving protection method thereof are provided. The display device includes a timing controller and a source driver. The timing controller encrypts a verification data to generate a first encryption signal. The source driver coupled to the timing controller receives the first encryption signal. The source driver decrypts the first encryption signal to obtain a first decryption data. The source driver encrypts the first decryption data to generate a second encryption signal. The source driver outputs the second encryption signal to the timing controller. The timing controller decrypts the second encryption signal to obtain a second decryption data. When the timing controller determines that the second decryption data matches the verification data, the timing controller enables the source driver to perform display driving.
