LED표시부(40)는 다수개의 발광다이오드(LED; Light-emitting diode)를 포함하며, 제어부(30)로부터 인가되는 표시제어신호에 따라 LED를 점등한다. 이 LED표시부(40)는 디지탈방송수신기 세트의 디스플레이패널에 부착된다. 또한, 도 1의 장치는 제어부(30)로부터 인가되는 표시제어신호에 따라 수신되는 방송신호의 세기에 대응하는 OSD문자를 텔레비젼 화면에 표시하는 온스크린디스플레이(OSD; On Screen Display)부(50)를 포함한다.1 is a view showing a digital broadcast receiver according to a preferred embodiment of the present invention. The apparatus shown in FIG. 1 includes a tuner unit 10 which receives a broadcast signal of a desired channel through an antenna 1. The intensity detector 20 detects the intensity of the signal received by the tuner 10 and outputs the intensity to the controller 30. The controller 30 outputs a display control signal based on the detected intensity. The LED display unit 40 includes a plurality of light-emitting diodes (LEDs), and lights up the LEDs according to a display control signal applied from the controller 30. This LED display portion 40 is attached to the display panel of the digital broadcast receiver set. In addition, the apparatus of FIG. 1 has an On Screen Display (OSD) unit 50 for displaying OSD characters corresponding to the strength of a broadcast signal received according to a display control signal applied from the controller 30 on a television screen. It includes.

도 2는 본 발명의 실시예에 따른 방송신호의 세기를 표시하는 디지털방송수신기의 디스플레이 패널을 보여주는 도면이다. 전술한 바와같이, LED표시부(40)는 디스플레이 패널(B)에 부착되며, 제어부(30)의 제어신호에 따라 수신되는 영상신호의 세기에 대응하는 소정 갯수의 LED가 점등된다. 또한, 텔레비젼 화면(A)에는 영상신호의 수신되는 세기에 대응하는 OSD문자가 표시된다.2 is a view showing a display panel of a digital broadcast receiver for displaying the strength of a broadcast signal according to an embodiment of the present invention. As described above, the LED display unit 40 is attached to the display panel B, and a predetermined number of LEDs corresponding to the intensity of the image signal received according to the control signal of the controller 30 is turned on. The television screen A also displays OSD characters corresponding to the received intensity of the video signal.

튜너부(10)는 안테나(1)로부터 희망하는 채널의 방송신호를 수신한다. 세기검출부(20)는 수신된 방송신호의 세기를 검출하여 제어부(30)로 출력한다. 제어부(30)는 검출된 세기에 대응하는 수의 LED를 점등시키도록 제어하는 표시제어신호를 LED표시부(40)로 출력한다. LED표시부(40)는 제어부(30)로부터 인가되는 표시제어신호에 따라 소정 갯수의 LED를 점등한다. 예를들어, 희망하는 채널에 수신되는 방송신호가 없는 경우, 제어부(30)는 어떤 LED도 점등되지 않도록 LED표시부(40)를 제어한다. 제어부(30)는 수신되는 방송신호가 텔레비젼 화면에 디스플레이 될 수 없는 세기를 갖는 경우, LED를 1개만 점등시키도록 LED표시부(40)를 제어하며, 수신되는 방송신호가 텔레비젼 화면에 디스플레이 될 수 있는 세기를 가지면, LED를 모두 점등시키도록 LED표시부(40)를 제어한다.The tuner unit 10 receives a broadcast signal of a desired channel from the antenna 1. The strength detector 20 detects the strength of the received broadcast signal and outputs the strength to the controller 30. The controller 30 outputs a display control signal to the LED display unit 40 for controlling the LEDs corresponding to the detected intensity to be turned on. The LED display unit 40 lights a predetermined number of LEDs according to the display control signal applied from the control unit 30. For example, when there is no broadcast signal received on a desired channel, the controller 30 controls the LED display unit 40 so that no LED is lit. If the received broadcast signal has an intensity that cannot be displayed on the television screen, the controller 30 controls the LED display unit 40 to turn on only one LED, and the received broadcast signal may be displayed on the television screen. If the strength is, the LED display unit 40 is controlled to light all of the LEDs.
