Abstract

본 발명은 OSD신호의 컬러제어방법에 관한 것으로, ABL전류검출부(38)에 의해 검출되는 상기 ABL전류치의 레벨을 기준치와 비교하여 화면이 밝은 상태이면 상기 CRT장치(34)상에 표시되는 OSD신호의 컬러를 변경하게 되고, 상기 ABL전류검출부(38)에 의한 ABL전류의 검출은 상기 OSD신호에 의한 제어상태의 화면표시가 수행되는 제어신호의 입력시에 실행되며, 상기 OSD신호의 컬러변경은 상기 OSD신호의 R/G/B 컬러량을 가감하여 수행되도록 하여 화면의 휘도가 높은 경우에 OSD신호를 암컬러화하여 OSD 신호의 인식이 용이하도록한 것이다.The present invention relates to a color control method of an OSD signal, the OSD signal displayed on the CRT device 34 when the screen is bright compared to the reference value level of the ABL current value detected by the ABL current detector 38 The ABL current is detected by the ABL current detection unit 38 at the time of input of a control signal in which a screen display of a control state by the OSD signal is performed, and the color change of the OSD signal is performed. The R / G / B color amount of the OSD signal is added or subtracted so that the OSD signal is darkened when the brightness of the screen is high, so that the OSD signal can be easily recognized.

Claims

And a flyback transformer (36) for generating a high pressure for driving the CRT device (34) for reproducing the video signal processed by the video signal processing means (30). In a television which detects a current flowing on the primary side of the circuit 36 as an automatic luminance limiting (ABL) current and controls the brightness of the screen, the level of the ABL current value detected by the ABL current detecting means 38 is compared with a reference value. And controlling the color of the OSD signal displayed on the CRT device (34) when the screen is bright.

The color of the OSD signal according to claim 1, wherein the detection of the ABL current by the ABL current detection means 38 is performed upon input of a control signal in which screen display of a control state by the OSD signal is performed. Control method.

The method of claim 1, wherein the color change of the OSD signal is performed by adding or subtracting the R / G / B color amount of the OSD signal.
