The Tektronix 4114 is a graphics terminal that uses a 19" direct-view storage CRT.
Typically, the 4114 is connected to a computer via RS-232. There is an on-screen "dialog area" where a textual interaction with the computer can be seen. The computer can also send drawing commands to the 4114, which are rendered by the 4114. The microprocessor in the 4114 is the Intel 8086.

From Tekscope June 1981:
With flicker-free refresh it is sometimes difficult to distinguish between refreshed and stored images on the screen. The 4114 Color Enhanced Refresh option resolves that difficulty by displaying all refresh vectors in a second color. The color-refresh DVST displays stored information in the usual green color, while refreshed objects appear as a yellowish orange hue easily distinguishable from the stored information.
Color refresh is accomplished by using a mixture of red and green phosphors for the DVST screen. In refresh mode, the writing beam excites both red and green phosphors, resulting in a yellowish-orange trace on the screen. The refreshed information, however, is displayed at a current density lower than that required to store a charge image. To remain visible, the information must be continually refreshed. In storage mode, the writing beam also excites both red and green phosphors causing a momentary yellowish orange glow. In this case, the current density is high enough to store a charge image. After the writing beam draws the image, only the green phosphor continues to emit light. The red phosphor does not store because it requires a higher charge level to luminesce than does the green phosphor.
