61 / 103 page ![]() Data Sheet S15649EJ2V0DS 61 µ PD161622 5.12 Stand-by The µ PD161622 has a stand-by function. Input of a stand-by command is acknowledged when the STBY bit of the control register 1 (R0) is set to 1. When the stand-by command has been input, the µ PD161622 is forcibly placed in the VSS display status, and scans the frame being display to the end. When scanning is complete, all gate outputs are turned on, the charge of the pixel on the TFT panel is decreased to 0, and the output stage amplifier and internal oscillator are stopped. The stand-by function is valid for only the source driver IC; the gate IC ( µ PD161640) and power IC (µ PD161660) connected to the µ PD161622 are not controlled by this function. After executing the stand-by command, therefore, execute commands that turn off the regulator for the gate IC and power IC an turn off the DC/DC converter. When the stand-by status is released, turn on the DC/DC converter and the regulator of the gate IC and power IC, and then issue an ordinary operation command (STBY = 0), in the reverse order to which the stand-by command was input. |
