Abstract

전화착신표시 디스플레이장치는 전화벨이 울릴 때 공급된?? 전화벨 신호에 의해 펄스신호를 발생하는 펄스발생부와, 펄스신홍 의해 소정시간 동안 OSD 제어신호를 출력하는 마이크로 컴퓨터와, OSD 제어신호가 입력됨에 따라 전화착신을 알리는 소정 형태의 영상을 화면에 디스플레이 하는 OSD 영상신호를 출력하는 TTX부를 구비하므로써, 전화벨이 울릴 때 TV화면으 일부에 OSD영상을 소정시간 동안 디스플레이시켜 전화벨 소리를 듣지 못하는 경우에도 전화착신을 알 수 있도록 하며, 또는 TV 스피커에서 나오는 전화벨소리와 혼돈하는 경우가 발생되는 것을 방지한다.The caller ID display device is supplied when the phone rings. A pulse generating unit for generating a pulse signal by a telephone ring signal, a microcomputer that outputs an OSD control signal for a predetermined time by a pulse signal, and a predetermined type of image for notifying call reception as the OSD control signal is inputted. The TTX unit outputs OSD video signal so that when the phone rings, the OSD video is displayed on a part of the TV screen for a predetermined time so that the incoming call can be recognized even when the phone does not hear the ringing, or the phone ringing from the TV speaker. To prevent the occurrence of confusion.
