Abstract: A display module and a display apparatus are provided in the present disclosure. The display module includes a backlight assembly and a display anti-peep assembly. The display anti-peep assembly is on a light-exiting side of the backlight assembly; and the display anti-peep assembly includes a display assembly and an anti-peep assembly; and the anti-peep assembly at least includes a plurality of light-blocking parts which is arranged along a direction in parallel with a plane where the display module is located. The display module further includes a first display mode and a second display mode. In the first display mode, the anti-peep assembly is in an operating state, and a light-exiting angle of the anti-peep assembly is ?1; and in the second display mode, the anti-peep assembly is not in an operating state, and the light-exiting angle of the display anti-peep assembly is ?2, where ?1<?2.

Abstract: Embodiments of the present disclosure provide a device and a method for detecting breakage of a substrate and a substrate transfer system. The device includes a first electrode and a second electrode arranged oppositely, a power source, and a detector. The power source may provide an alternating current voltage to the first electrode and the second electrode. The detector is arranged between the power source and the first electrode or the second electrode and may detect, when the substrate is placed between the first electrode and the second electrode, a current value in the substrate, and determine whether the substrate is damaged based on the detected current value.

Abstract: A control contact pin is connected to a GND when an electronic apparatus is connected to an AC adapter. The control contact pin, when connected to the GND, receives an input of a control signal output by the electronic apparatus. A detection unit detects whether the control contact pin is connected to the GND and whether the control contact pin receives the input of the control signal. When the detection unit detects that the control contact pin is not connected to the GND or the control contact pin is connected to the GND and receives the input of the control signal, a control unit stops an operation of a switching unit. When the detection unit detects that the control contact pin is connected to the GND and yet does not receive the input of the control signal, the control unit operates the switching unit.

Abstract: An electronic device includes a function extension device that includes a first slim line connector based on SATA, and a terminal device connected to the function extension device. The terminal device includes a detection circuit for outputting a first and second detection signals which indicate whether connection to the function extension device is established and a type of the function extension device, respectively, a control circuit for detecting whether connection to the function extension device is established and for determination of the type of the function extension device by the first and second detection signals, and a second slim line connector based on SATA. The first and second detection signals are signals that passes through pins P1 and S4 of the second slim line connector, respectively, the function extension device connects a pin P1 with a pin S4 of the first slim line connector.
