Abstract

PURPOSE: To obtain the letter and graph display unit having the self diagnosis function, by providing the fundamental timing generation section with the display unit, and picking up the test pattern signal of high reliability directly from this and feeding it to the video display section.
CONSTITUTION: The unit consists of the control section 1 generating the various control, video and synchronizing signal, video display 2 displaying picture, and cables 3 connecting them. The control section 1 is provided with the input and output control section 6 performing input and output control of the information from the keyboard 4 and external processor 5, memory section 7 memorizing the coded display information, character generator 8 converting the display information into video signal, transmission circuit 10 driving the synchronizing signal generator 9 and cable 3, and the fundamental timing generator 11 giving timing signal to each section. Further, the display section 2 is provided with the CRT 15. Thus, the test pattern signal is directly picked up from the generating section 11, it is fed to the display section and the judgement of the failured parts can be made easy.
