Abstract

본 발명은 머지등에 의한 텔레비젼 내부의 오염을 전자총의 히터의 빛에 의한 조도를 감지하여 판별하고, 이를 화며상에 OSD문자를 표시해주도록 한 텔레비젼의 오염상태 표시장치에 관한 것으로, CRT의 전자총부근에 설치되어 조도를 감지하는 조도센서(4)와, 상기 조도센서(4)의 특정사항의 증가에 따라 스위칭되어 감지 신호를 생성하는 조도판별부(5), 오염상태를 알리기 위한 OSD문자를 표시하는 OSD발생장치(7), 상기 조도판별부(5)의 오염상태에 대한 감지신호에 따라 상기 OSD메모리(6)와 OSD발생장치(7)를 제어하여 텔레비젼의 화면상으로 텔레비젼의 오염상태를 표시제어하는 마이크로 컴퓨터(8)를 포함하여 구성된 것을 특징으로 한다.The present invention relates to a pollution state display device of a television which detects the illumination of the inside of the television by a merge light by detecting the illuminance by the light of the heater of the electron gun and displays the OSD text on the image. Installed illuminance sensor (4) for detecting the illuminance, and illuminance discrimination unit (5) to switch in accordance with the increase of the specific details of the illuminance sensor (4) to generate a detection signal, to display the OSD character for informing the contamination state Displaying the contamination state of the television on the screen of the television by controlling the OSD memory (6) and the OSD generator (7) in accordance with the detection signal for the contamination state of the OSD generator (7), the illuminance determination unit (5) It is characterized by including a microcomputer 8 for controlling.
