Abstract

본 발명은 OSD신호의 화면표시제어방법에 관한 것으로, 해당의 텔레비전에 대한 제어신호의 입력시 ABL전류검출부(38)에 의해 검출되는 상기 ABL전류치의 레벨을 검출하고, 그 검출된 ABL전류치가 기준치 이상이면 OSD신호가 표시되는 화면상의 위치를 하프-블랭킹처리하게 되고, 상기 OSD신호의 하프블랭킹처리는 그 OSD신호와 대비되는 보색의 컬러성분에 의해 실행되도록 해서 휘도가 높은 화면에 표시되는 OSD신호에 대한 인식도가 하프-블랭킹처리에 의해 증대되도록 한 것이다.The present invention relates to an on-screen display control method of an OSD signal, and detects the level of the ABL current value detected by the ABL current detection unit 38 when inputting a control signal for a corresponding television, and the detected ABL current value is a reference value. If it is, the half-blanking process is performed on the screen where the OSD signal is displayed, and the half-blanking process of the OSD signal is performed by complementary color components contrasted with the OSD signal so that the OSD signal is displayed on the screen having high luminance. The degree of recognition is increased by the half-blanking process.

제2도는 제1도에 도시된 ABL전류검출부의 구성예를 나타낸 도면,2 is a diagram showing an example of the configuration of the ABL current detection unit shown in FIG.

제3도는 본 발명에 따른 OSD신호의 화면표시제어방법을 설명하는 플로우차트이다.3 is a flowchart illustrating a method for controlling screen display of an OSD signal according to the present invention.

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 controls the brightness of the screen by detecting a current flowing to the primary side of the circuit 36 as an automatic luminance limiting (ABL) current, it is detected by the ABL current detecting means 38 at the time of inputting a control signal to the television. Detecting the level of the ABL current value and half-blanking the position on the screen where the OSD signal is displayed if the detected ABL current value is greater than or equal to the reference value to increase the visual recognition of the OSD signal. Screen display control method.

The method of controlling an on-screen display of an OSD signal according to claim 1, wherein the detection of the ABL current is performed upon generation of a control signal in which an OSD signal for displaying a control state of a television is generated.

The method according to claim 1, wherein the half-blanking processing of the OSD signal is performed by complementary color components that contrast with the OSD signal.
