An electronic product having a display window for displaying the operation-related information of the electronic product according to the present invention for achieving the above object, the operation of the plurality of light emitting diodes and the operation-related information of the electronic product embedded in the display window And an input unit for inputting a command, and a control unit for controlling at least one of the plurality of light emitting diodes to flash to indicate to the outside that the operation command has been input when the operation command is input from the input unit.

The input unit is a remote controller capable of inputting an operation command from a remote place, and an operation button provided in the main body of the electronic product.

Preferably, the plurality of light emitting diodes are seven segments, and the light emitting diodes indicating that an operation command is input to the outside are seven-segment decimal point LEDs.

Therefore, since a separate receiving check light emitting diode is not required, the circuit configuration of the front panel is simple and effective in terms of economy.

Hereinafter, with reference to the drawings will be described an embodiment of the present invention in more detail.

2 is a schematic block diagram of an electronic product according to an embodiment of the present invention, the electronic product having a front panel 200, a controller 300, a remote controller 400, and the like. The front panel 200 includes an input unit 20 provided with operation buttons for inputting an operation command of an electronic product, and an infrared detection unit 70 for detecting an infrared signal for an operation command output from a remote place by the remote controller 400. And a display window 40 for externally displaying operation related information such as an environmental setting state and a power state of the electronic product.

The display window 40 is provided with seven segments 41 composed of eight light emitting diodes a to dp, as shown in FIG. 3. In general, the seven segments are divided into a cathode common type and an anode common type, and the seven segments 41 illustrated in FIG. 3 are cathode common types and include seven light emitting diodes a to g. The number is displayed via. In order to display a predetermined number, a negative number is applied to a common terminal, and a positive number is displayed on the seven segments 41 by applying a positive voltage to a terminal of the corresponding light emitting diode. Here, a decimal point light emitting diode (dp: decimal point) is used to display a decimal point taken by a single unit display of a number.

The controller 300 controls the decimal point light emitting diode dp to use as a reception check light emitting diode to inform a user whether an input signal is received when there is a signal input from the outside.

For example, in order to display the desired predetermined number '2' on the seven segments 41, a negative voltage is applied to the common terminal, and each light emitting diode (a, b, g, e) is displayed to display the number '2'. The number '2' is indicated by applying a positive voltage to the terminal of, d). At this time, the decimal point light emitting diode dp is controlled separately.

That is, when a signal is input from the remote controller 400 or the input unit 20, the controller 300 first detects an operation state of the decimal point light emitting diode dp. At this time, when the operation state of the decimal point light emitting diode dp is in the on state, it is switched to the off state.

In general, since the period of the input pulse is a unit of several msec, if the decimal point light emitting diode dp is repeatedly turned on / off every time the input pulse is input, the blinking operation is not clear due to the afterimage of the human eye. Therefore, the controller 300 must control the input pulse period to maintain the flashing operation of the decimal point light emitting diode dp at least 200 msec. After that, if there is no input for a predetermined time, the decimal point light emitting diode dp is turned off to stop the flashing operation.

On the other hand, as another embodiment, it is possible to indicate whether the input signal is received by blinking the numbers and characters currently displayed on the display window. For example, when the number '2' is displayed in the seven segments 41, when an input signal is received, the control unit 300 controls a positive voltage at a predetermined time interval to the terminals of the light emitting diodes (a, b, g, e, d). Supply and cut off to control flickering operation. Therefore, the number '2' flashes at a predetermined time interval, so that the user can be notified of the reception.

In addition to the above method, it is also possible to select a light emitting diode that is not currently used among a plurality of light emitting diodes of seven segments and use it as a reception check light emitting diode.

In the above, the input signal is received by using a decimal point light emitting diode (dp) and other light emitting diodes without using a separate receiving check light emitting diode, but the power supply or failure may be displayed. In a playback apparatus such as a VCR, a DVD, or the like, the presence or absence of a recording medium can be displayed, and its use can be variously applied.

4 is a front view of the front panel 200 of the electronic product according to an embodiment of the present invention, when the input signal which is an infrared signal output from the remote control 400 is input to the infrared sensor 70, the control unit 300 The controller controls the decimal point light emitting diode dp of the seven segments 41 embedded in the display window 40 to inform the outside of the reception of the input signal. Compared with the conventional front panel shown in FIG. 1, a separate reception check light emitting diode is not required.

Therefore, since a separate receiving check light emitting diode is not required, the circuit configuration of the front panel is simple and effective in terms of economy.

According to the present invention, it is possible to simplify the circuit configuration of the front panel and to provide electronic products with improved economic efficiency.
