  • Publication number: 20190387379
    Abstract: The invention efficiently realizes time division multiplexed channel access in a mixture of a vehicle-to-vehicle communication device using an approximate frequency band and a direct mobile communication terminal. The vehicle-to-vehicle communication device includes a mobile communication unit, a threshold storage unit that stores a threshold value as to whether or not a predetermined control channel for vehicle-to-vehicle communication is an idle channel, a level detector that outputs a predetermined detection signal when a radio wave intensity of the predetermined control channel is larger than the threshold value, and a timer unit that transmits a signal to the level detector when the time counting for a predetermined time expires. The mobile communication unit transmits the radio wave of the direct communication of the mobile communication when the level detector receives the signal and the radio wave strength of the predetermined control channel does not exceed the threshold value.

  • Publication number: 20190325797
    Abstract: The display device includes a display panel, gate line driving circuitry that includes gate drivers provided for each of gate lines, a control circuit, and a signal processing circuit. The control circuit supplies a control signal to at least one gate driver corresponding to a gate line to be scanned first in a unit period in which the gate lines are scanned. The gate driver which received the control signal is driven on the basis of the control signal, and the gate drivers in subsequent stages are each driven on the basis of a scanning signal of the gate driver in a preceding stage. The signal processing circuit outputs, on the basis of a scanning signal of at least one gate driver corresponding to a gate line to be scanned last in the unit period and the control signal, a detection signal that indicates whether the gate driver is normal.
