Abstract

PURPOSE:To display a response, by constituting so that a display color of a channel indicator can be changed when a television receiver receives a signal from a remote control device. CONSTITUTION:A seven-segment indicator 1 which can display two colors of green and red is used as a channel indicator 1 of a television receiver. As for this indicator, one segment is constituted of plural diodes different in light emitting color. When a remote control device does not output a switching signal, the display is green. When the switching signal is outputted, a transistor 9 is turned off and a transistor 10 is turned on only during that time, and a red light emitting diode for constituting the indicator 1 is lighted. Even in case when the fitting space is limited, a space for a response sign is not required separately.

Conventional configurations and their problems In recent television receivers, remote control devices have become widespread for switching reception channels, adjusting volume, and the like. In this type of television receiver with a remote control device, a response sign lamp is provided on the front panel of the television 5HQ4LtK to indicate that an operation from the remote control device dt has been accepted. However, in the case of a small-inch receiver with limited mounting space, there is no space for mounting a response sign lamp like this, so the operability is poor.

FIG. 2 shows the main structure of a television receiver with a remote control device in which the display device (1) of FIG. 1 is used for displaying reception channels, and the drive circuit for the display device (1). Note that a two-digit display is required to display the reception channel, but only one digit will be explained here. (2)
is the television receiver body (hereinafter referred to as TVNUT)

When a signal is sent from the transmitter (3), it is detected by the light receiving section (4) of the television set (2). Usually, in order to make the remote control signal strong against external noise, it is not a simple pulse signal, but one pulse is modulated by general transmission. This is tuned amplified and waveform shaped by the tuned amplification waveform shaping circuit (5), and then converted into a pulsed signal by the tuning circuit (5).
6). Here, the pulse is a positive pulse,
Normally it is set to "L" level.
