路。 In a circuit that adjusts the contrast of a display provided in a controlled station of a remote control device that controls a telecommunications system, the controlled station receives an operation to adjust the contrast of the display, and adjusts the contrast of a digital amount. an input unit that generates a signal for adjusting the contrast of the display device transmitted from a control station of the remote control device, and a communication unit that generates a digital contrast adjustment signal; the input unit and a switching unit that selects the digital contrast adjustment signal output from the communication unit; converts the digital contrast adjustment signal selected and sent out by the switching unit into an analog contrast adjustment voltage. D/
A contrast adjustment circuit for a display device, characterized in that the D/A conversion section sends out the analog amount of contrast adjustment voltage for adjusting the contrast of the display device to the display device.
