摘要： An output circuit may include a power supply terminal, a ground terminal, and an output terminal connected to a capacitive load. Depending on the state of a load control input signal, the output circuit performs selectively a charging-current supplying operation of supplying a charging-current from the power supply terminal to the capacitive load and a discharging-current withdrawing operation of withdrawing a discharging-current from the capacitive load to the ground terminal. An overcharging-current prevention switch is provided to detect a short circuit between the output terminal and the ground terminal so as to stop or suppress the charging-current supplying operation. An overdischarging-current prevention switch is provided to detect a short circuit between the output terminal and the power supply terminal so as to stop or suppress the discharging-current withdrawing operation.

The first-panel horizontal system pulse generation section and the second-panel horizontal system pulse generation section respectively generate a reference signal of a first-panel horizontal system output group and a reference signal of a second-panel horizontal system output group from signal VCOCLK1 output from the VCO. Thus, it is possible to simultaneously drive two different panels.
