LCD DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an LCD(liquid crystal display) display device which is constituted of a CRT(cathode-ray tube) system and an LCD system and in which it is made unnecessary to perform communications following to a specific communication protocol between the microcomputer of the CRT system and the microcomputer of the LCD system. SOLUTION: In this device, the state of an input signal which is detected by the CRT microcomputer 1 and ASPECT information which is being recognized by the CRT microcomputer 1 are converted into states in which an LCD microcomputer 3 can recognize them by a detecting circuit 7 and they are supplied to the LCD microcomputer 3.
