Description

지능형 표시장치{intelligent diplay device}Intelligent display device

본 발명은 전자앨범(digital album)이나 전자 사진첩등의 LED나 LCD 표시장치에 관한 것으로, 더욱 상세하게는 LED나 LCD 표시장치가 설치된 공간의 TV가 온(ON)된 상태, 소음 등을 감시하고, 감시된 상태에 따라서 밝기를 제어하는 지능형 표시장치에 관한 것이다.The present invention relates to an LED or LCD display device such as an electronic album (digital album) or an electronic photo album, more specifically, to monitor the state of the TV (ON), noise, etc. in the space where the LED or LCD display device is installed The present invention relates to an intelligent display device that controls brightness according to a monitored state.

벽등에 설치되는 전자앨범은 자체 저장되거나, USB 등으로 연결되어 외부 전자기기로부터 공급되는 다양한 정지영상, 동영상 데이터를 LED나 LCD 표시수단에 표시하도록 하는 장치이다.The electronic album installed on the wall is a device which displays various still images and video data stored on its own or connected by USB, etc., supplied from an external electronic device on the LED or LCD display means.

또한 이러한 전자앨범은 TV, 컴퓨터의 일부 기능으로 TV, 컴퓨터 모니터에 저장된 영상을 표출하도록 구현되기도 한다.In addition, the electronic album is implemented as a part of a TV and a computer to display an image stored in the TV and a computer monitor.

TV나 컴퓨터와 별도로 설치되는 전자앨범은 책상이나 벽등에 설치되게 되고, 특정 영상이 표시수단에 항상 표출되게 설정하게 되나, 설치공간 예를 들어 방안에 사람이 없는 경우에도 영상이 표출되게 되어 전력이 낭비되게 된다.An electronic album installed separately from a TV or a computer is installed on a desk or a wall, and a specific image is always displayed on the display means. However, even if there is no person in the room, the image is displayed. It is wasted.

또한 설치공간에 TV등이 켜져 있어 설치공간 내의 사람이 TV 등을 시청하기 때문에 전자앨범을 보지 않는 경우에도 표시수단에 연속적으로 영상이 표출되게 되어 전력이 낭비되게 된다. In addition, since the TV light is turned on in the installation space, a person in the installation space watches the TV, and thus even when the electronic album is not viewed, the image is continuously displayed on the display means, and the power is wasted.

본 발명의 지능형 표시장치(1)는 표시부(13)와, 표시부(13)의 밝기를 제어하기 위하여 다양한 밝기모드가 저장되며 저장된 응용프로그램에 의하여 지정된 밝기모드에 따라서 제어대상들을 제어하는 제어부(11)와, 설치공간 내에 사람의 존재유무를 감지하여 제어부(11)로 출력하는 감지센서(19), 사용자가 제어부(11)의 모드를 설정 입력하기 위한 모드 입력부(21), USB 포트로부터 입력되는 영상데이터를 처리하는 EPF 모듈(Electronic Picture Frame module)과, 제어부(11)의 제어신호에 따라서 표시부(13)의 백라이트를 제어하는 백라이트 구동부(17)와, 영상데이터를 입력받아 표시부(13)에 영상을 표출시키는 영상구동부(15)로 이루어진다.The intelligent display device 1 of the present invention includes a display unit 13 and a control unit 11 for controlling the control targets according to the brightness mode specified by the stored application program in which various brightness modes are stored to control the brightness of the display unit 13. ), A sensor 19 for detecting the presence of a person in the installation space and outputting it to the control unit 11, a mode input unit 21 for the user to set and input a mode of the control unit 11, and a USB input from the USB port. An EPF module (Electronic Picture Frame module) for processing image data, a backlight driver 17 for controlling the backlight of the display unit 13 according to a control signal of the controller 11, and image data are inputted to the display unit 13. It consists of an image driver 15 for displaying an image.

감지센서(19)는 사람의 유무를 감지하는 적외선 센서, 설치공간내의 밝기를 감지함으로써 결국 전등의 온/오프 상태를 감지하는 광감지센서, 소음을 감지하는 음감지센서 등 다양하게 구성될 수 있다.The detection sensor 19 may be configured in various ways, such as an infrared sensor for detecting the presence or absence of a person, an optical sensor for detecting an on / off state of a light, and a sound sensor for detecting noise. .

본 발명을 동작시키기 위해서 사용자는 모드입력부를 통하여 모드를 입력시킨다.In order to operate the present invention, the user inputs a mode through the mode input unit.

사용자가 모드 입력을 선택하게 되면, 표시부(15)에는 설치공간내의 사람의 존재 유무, 전등의 온/오프 상태, TV의 온/오프 상태에 따라서 밝기를 설정할 수 있는 OSD 화면을 표출되게 되고, 사용자가 OSD 화면의 안내에 따라서 밝기를 설정하고, 설정된 밝기모드는 제어부(11)에 저장되게 된다. When the user selects the mode input, the display unit 15 displays an OSD screen for setting the brightness according to the presence or absence of a person in the installation space, the on / off state of the light, the on / off state of the TV, the user The brightness is set according to the guidance of the OSD screen, and the set brightness mode is stored in the controller 11.

표 1은 제어부(11)에 설정되는 밝기모드를 예시한 것이다.Table 1 illustrates the brightness mode set in the control unit 11.

TV 오프TV off TV 온TV On 사람 유Man u 전등 온 상태 100%, 전등 오프 상태 80%100% light on, 80% light off 전등 온 상태70%, 전등 오프 상태 50%Light on 70%, light off 50% 사람 무Man draws 0%0% 0% 0%

표 1의 설정상태는 설치공간내에 사람이 존재하고 TV가 오프된 상태, 전등 온 상태에서 지능형 표시장치는 최대밝기 100%를 갖도록 하고, 사람이 존재하고 TV가 오프된 상태인 경우에도 전등이 오프된 상태에서는 최대밝기로 지능형 표시장치가 동작하게 되면 사람에게 눈의 피로감을 주게 되므로 최대밝기의 80%의 밝기로 영상이 표출되도록 한 것이다. 또한 표 1의 모드는 사람이 존재하고 TV가 온 된 상태, 전등이 온된 상태에서는 시선이 표시부에 집중되지 않기 때문에 최대밝기의 70%로 영상이 표출되도록 하고, 전등이 오프된 상태에서는 50%로 표출되도록 하며, 사람이 없는 상태에서는 0%, 즉 지능형 표시장치(1)는 오프 상태에 놓이게 설정한 것이다.The setting of Table 1 shows that the intelligent display device has a maximum brightness of 100% when there is a person in the installation space and the TV is turned off and the lamp is turned on, and the light is turned off even when a person is present and the TV is turned off. In this state, when the intelligent display device operates at the maximum brightness, the eyes are tired to the human being, so the image is displayed at the brightness of 80% of the maximum brightness. In addition, in the mode of Table 1, when the human being is present and the TV is turned on and the lamp is turned on, the eyes are not focused on the display unit, so that the image is displayed at 70% of the maximum brightness and 50% when the lamp is turned off. In the absence of a person, 0%, that is, the intelligent display device 1 is set to be in an off state.

이와 같이 설정된 상태에서, 제어부(11)는 TV로부터 입력되는 온/오프 신호와 감지센서(19)로 부터 입력되는 감지상태와 설정된 모드에 따라서 백라이트 구동부(17)를 구동하는 구동신호를 생성하여 전송한다.In this state, the controller 11 generates and transmits a driving signal for driving the backlight driver 17 according to the on / off signal input from the TV and the sensing state input from the sensor 19 and the set mode. do.

표시부(13)가 100%의 밝기를 갖는 경우에는 제어부(11)로부터 백라이트 구동부(17)에 전송되는 구동신호의 펄스가 디밍(dimming) 제어되는 경우에 온지속시간이 한 주기의 100% 라면, 표시부(13)가 50%의 밝기를 갖는 경우의 펄스의 온지속시간은 한 주기에서 50%로 된다. 이와 같이 백라이트 구동부의 밝기제어는 통상적인 방법에 의한 제어부(11)의 구동신호의 제어에 의하여 이루어지므로 상세한 설명을 약하기로 한다.When the display unit 13 has a brightness of 100%, when the ON duration is 100% of one period when the pulse of the driving signal transmitted from the controller 11 to the backlight driver 17 is dimmed controlled, When the display portion 13 has a brightness of 50%, the on duration of the pulse is 50% in one cycle. As such, the brightness control of the backlight driver is performed by controlling the driving signal of the controller 11 according to a conventional method, and thus the detailed description thereof will be omitted.
