The invention discloses electronic equipment, a display system, an integrated control device of the display system and an authentication method. The integrated control device comprises a display unit,a sensor unit, a processor and a nonvolatile memory, wherein the display unit is used for providing display driving signals for a display screen; the sensor unit is used for providing driving signalsfor at least one sensor, receiving sensing signals, and converting the sensing signals into sensing data; the processor is used for controlling the display unit and the sensor unit, responds betweena secret key preset request of a main control unit of the electronic equipment and the main control unit to negotiate an initial secrete key, responds the connection authentication request of the maincontrol unit and performs connection authentication by the aid of the initial secrete key and the main control unit; the nonvolatile memory is used for storing the initial secrete key. The integratedcontrol device has the functions of display driving, touch driving and connection authentication, and accordingly, the safety is improved and the system resources are saved.
Description
technical field [0001] The present application relates to the field of display technology, and more specifically, to electronic equipment, a display system and its integrated control device, and an authentication method. Background technique [0002] With the advent of the era of big data, the security of massive data has become a key issue that must be effectively resolved in "human-computer interaction". The display screens configured on electronic devices are not only used to display images and texts, but also further develop into an important way of human-computer interaction. A touch sensor, a fingerprint sensor, an acoustic sensor, an optical sensor, etc. can be integrated on the display screen to form a display system. Users can directly input text, select icons, gesture control, sound, face recognition and other operations on the display. [0003] As the entrance of information collection and the exit of display content, the display system plays an irreplaceable an...
