Abstract
A display control apparatus includes at least one output control unit, and each output control unit comprises: a tri-state buffer receiving, as a signal input, a one-bit color signal, and receiving, as a control input, a one-bit intermediate color control signal for controlling an intermediate color of the color signal, and setting its output in one of the following three states: a state of outputting a first voltage, a state of outputting a second voltage, and a high impedance state, on the basis of the color signal and the intermediate color control signal; a first resistor having an end connected to a power supply, and the other end connected to the output of the tri-state buffer; and a second resistor having an end connected to the ground, and the other end connected to the output of the tri-state buffer. Therefore, it is possible to provide a display control apparatus that is able to perform intermediate color display, with reduced manufacturing cost and reduced power consumption.
