This article describes a video interface circuit between a driver circuit and a display monitor. The video interface circuit is commonly used as an interface for three types of display monitor. Output characteristics of the video interface circuit are selectively switched to adapt to the input characteristics of the display monitor connected. (Image Omitted) There are three types of video interface between a display driver circuit and a display monitor, as shown in Fig. 1. When an input stage of a circuit of the display monitor has a circuit configuration as shown in the upper right area of Fig. 1, the final stage of the display drive circuit has to have a circuit configuration like that in the upper left area of Fig. 1. This combination is called a Type 1 interface. Similarly, Type 2 and Type 3 interfaces are shown in Fig.
