본 발명은 반사율 조절이 가능한 OLED 룸미러에 관한 것으로서, 보다 상세하게는 야간 운전시 후방차량의 전조등이나 주간의 햇빛에 의해 룸미러에 비춰지는 광도를 감지하여 감지된 광도의 크기에 따라 OLED(Organic Light Emitting Diode) 소자의 밝기를 조절하여 눈부심을 줄일 수 있도록 한 반사율 조절이 가능한 OLED 룸미러에 관한 것이다. The present invention relates to an OLED room mirror having an adjustable reflectivity, and more particularly, OLED (Organic) according to the detected intensity of light detected by detecting the brightness of the rearview mirror by the headlight of the rear vehicle or the daytime sunlight during driving at night. Light Emitting Diode) The present invention relates to an OLED room mirror capable of adjusting reflectance to reduce glare by adjusting brightness of a device.

일반적으로 자동차에는 주행중 운전자가 전방을 주시하면서 그와 동시에 후방을 주시할 수 있도록 차체내의 천정에 룸미러가 설치되어 있고, 차량외부로는 프론트 도어 외측의 후사경인 사이드 미러가 설치되어 있다. In general, a vehicle is provided with a room mirror on the ceiling of the vehicle body so that the driver can watch the front while driving and the rear at the same time, and a side mirror, which is a rear view mirror outside the front door, is installed outside the vehicle.

또한, 자동차에는 어두운 곳이나 야간에 주행하게 될 때 전방을 밝게 비쳐주어 운전자의 시야를 확보해 줄 수 있도록 된 전조등으로서 전조등이 설치되어 있다. In addition, the headlights are installed as headlights to brighten the front and to secure the driver's vision when driving in a dark place or at night.

따라서, 야간에 차량을 운전할 때 후방에서 따라오는 차량의 전조등 불빛이 전방 차량의 실내 룸미러를 통하여 비칠 경우, 전방 차량의 운전자는 시야의 방해를 받게 되고 특히, 후방 차량이 상향등을 조작하였을 경우 전방 차량의 운전자는 심한 불쾌감과 함께 안전운행을 방해하는 요인으로 작용하게 된다.Therefore, when driving the vehicle at night, when the headlights of the vehicle following the rear light shines through the interior room mirror of the vehicle in front of the vehicle, the driver of the vehicle in front of the vehicle is obstructed, especially when the vehicle behind the operation of the high beam The driver of the vehicle, along with severe discomfort, acts as a factor that hinders safe driving.

그래서 일부 운전자들은 후방 차량에 의한 눈부심을 방지하기 위해 수동으로 룸미러의 각도를 조절하여 눈부심을 방지하기도 한다. Therefore, some drivers manually prevent the glare by adjusting the angle of the room mirror to prevent glare from the rear vehicle.

따라서, 이러한 불편함을 해소하기 위해 최근에는 ECM(Electro Chromic Mirror) 기술을 이용한 룸미러가 등장하여 자동으로 거울면의 반사율을 조절하여 눈부심을 방지하도록 하고 있다. Therefore, in order to alleviate this inconvenience, a room mirror using ECM (Electro Chromic Mirror) technology has recently emerged to automatically adjust the reflectance of the mirror surface to prevent glare.

이와 같은 ECM 룸미러는 전자식 크롬조광 미러를 일컫는 말로써, 차량의 주행시 주위 조건에 따라 거울면에 빛 반사율이 자동으로 조절(약 6~80%)되며, 특히 야간 주행시 후방 차량의 불빛을 룸미러 내부의 센서가 자동 감지하여 흡수, 눈부심을 방지해 줌으로써 안전한 시계를 확보할 수 있도록 하고 있다. The ECM room mirror refers to an electronic chrome dimming mirror, and the light reflectance is automatically adjusted (about 6 to 80%) on the mirror surface according to the ambient conditions when the vehicle is driving. The internal sensor automatically detects and prevents absorption and glare to secure a safe watch.

이와 관련된 특허로써 공개특허 특1998-022245호(1998. 07. 06.) "차량용 사이드미러의 반사광 조절장치"에서는 야간에 후방차량의 전조등과 주간에 햇빛이 룸미러를 비추는 광도를 감지하여 감지된 광도의 크기에 따라 제어부에서 구동모터를 작동시켜 제 1내지 제 2차 편광유리판의 결의 각도를 조절하여 반사광의 밝기를 제어하여 반사광을 조절하고 있다.In this patent, Korean Patent Application Laid-Open No. 1998-022245 (1998. 07. 06.) "Reflective light control device of a side mirror for a vehicle" detects the headlight of a rear vehicle at night and the brightness of sunlight illuminating the room mirror during the day. The control unit operates the driving motor according to the intensity of light to adjust the angle of determination of the first to second polarizing glass plates to control the brightness of the reflected light to adjust the reflected light.

그러나 이와 같이 구동모터를 통해 편광유리판의 결을 조절하여 반사광의 발기를 조절할 경우 그 반응속도가 3∼6초로 비교적 느려 운전자의 시력을 보호하는데에는 미흡한 문제점이 있었다. However, when controlling the erection of the reflected light by adjusting the texture of the polarizing glass plate through the drive motor as described above, the response speed is relatively slow to 3 to 6 seconds, which is insufficient to protect the driver's vision.

따라서, 반응속도를 향상시키며 운전자의 눈부심을 최소화하기 위해 공개특허 특2003-0091898호(2003. 12. 03) "반사율 조절이 가능한 엘시디 미러"에서는 반응속도를 0.2초 이하로 개선하여 운전자의 눈부심을 최소화하였으며 엘시디 평광판의 흡수에 의한 빛의 반사율 저하를 최소화하여 미러의 반사율을 증대시키며 차량에 장착하기 용이하도록 구동전원을 휴대용 배터리로 사용하고 있다. Accordingly, in order to improve the reaction speed and minimize the glare of the driver, the LCD mirror capable of adjusting the reflectance is improved in the response speed to 0.2 seconds or less in order to reduce the glare of the driver. It minimizes the decrease in reflectance of light due to the absorption of LCD flat panel, increases the reflectivity of the mirror, and uses the driving power as a portable battery for easy installation in a vehicle.

그러나, 위와 같이 엘시디 미러의 경우 엘시디 제조 공정에서 액정 특성상 그 제작 공정이 복잡한 문제점이 있다. However, in the case of LCD mirror as described above, there is a problem that the manufacturing process is complicated due to the liquid crystal characteristics in the LCD manufacturing process.

이하, 본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 설명한다. 또한 본 실시예는 본 발명의 권리범위를 한정하는 것은 아니고, 단지 예시로 제시된 것이다. Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. In addition, this embodiment is not intended to limit the scope of the present invention, but is presented by way of example only.

도 1은 본 발명에 의한 반사율 조절이 가능한 OLED 룸미러를 나타낸 블록구성도이다. 1 is a block diagram showing an OLED room mirror capable of adjusting the reflectance according to the present invention.

여기에 도시된 바와 같이 차량의 루프라이닝(미도시)에 설치되어 정후방을 감시하기 위한 OLED 미러(30)와, OLED 미러(30)의 소정위치에서 주행중 룸미러에 비춰지는 전조등 또는 햇빛의 밝기를 감지하기 위한 광센서(10)와, 광센서(10)의 값을 입력받아 OLED 미러(30)의 발광 밝기를 제어하는 제어부(20)로 이루어진다. As shown here, the OLED mirror 30 is installed on the roof lining (not shown) of the vehicle and the brightness of the headlight or sunlight shining on the room mirror while driving at a predetermined position of the OLED mirror 30 is shown. It consists of a light sensor 10 for detecting the light, and a control unit 20 for controlling the light emission brightness of the OLED mirror 30 by receiving the value of the light sensor 10.

또한, OLED 미러(30)는 도 2에 도시된 바와 같이 거울면을 이루는 투명기판(32)과, 투명기판(32) 상부 전면에서 반투과 성질을 갖도록 형성된 양전극(34)과, 양전극(34) 상부 전면에 유기발광을 위한 유기발광층(36)과, 유기발광층(36) 상부 전면에 형성된 음전극(38)으로 이루어져 간단한 증착공정에 의해 간단하게 형성하게 된다. In addition, as shown in FIG. 2, the OLED mirror 30 includes a transparent substrate 32 forming a mirror surface, a positive electrode 34 formed to have a transflective property on the entire upper surface of the transparent substrate 32, and a positive electrode 34. The organic light emitting layer 36 for organic light emission on the upper surface and the negative electrode 38 formed on the upper surface of the organic light emitting layer 36 are simply formed by a simple deposition process.

이때, 유기발광층(36)은 단색광으로써 화소 구분없이 전면에서 발광하도록 형성하여 발광된 빛과 거울에 반사되는 빛의 조합으로 거울에 반사되는 빛의 강도를 조절할 수 있도록 한다. At this time, the organic light emitting layer 36 is formed to emit light from the front surface as a monochromatic light without distinguishing the pixels so that the intensity of the light reflected on the mirror can be adjusted by a combination of the emitted light and the light reflected on the mirror.

따라서, OLED 미러(30)가 동작하지 않을 경우에는 양전극(34)의 반투과 성질에 의한 반사성질에 의해 OLED 미러(30)에 비치는 사물이 반사하는 거울로써 사용하게 되고 반사율을 조절하기 위해 OLED 미러(30)가 동작하게 되면 투과성질에 의해 OLED 미러(30)의 유기발광층(36)에 발광된 빛이 양전극(34)을 통해 발광되면서 OLED 미러(30)에 비치는 햇빛이나 전조등의 빛과 조합되어 빛의 강도를 줄여 눈부심을 방지하게 된다 Therefore, when the OLED mirror 30 does not operate, it is used as a mirror reflecting an object reflected on the OLED mirror 30 by the reflective property of the semi-transmissive property of the positive electrode 34 and the OLED mirror to adjust the reflectance. When the 30 is operated, the light emitted from the organic light emitting layer 36 of the OLED mirror 30 is transmitted through the positive electrode 34 by the transmissive property, and is combined with the light of the sunlight or the headlamp reflected on the OLED mirror 30. Reduces light intensity to prevent glare

이와 같이 이루어진 본 발명의 작동을 도 3에 도시된 본 발명에 의한 반사율 조절이 가능한 OLED 룸미러의 작동을 설명하기 위한 흐름도를 참조하여 설명하면 다음과 같다. The operation of the present invention made as described above will be described with reference to a flowchart illustrating the operation of the OLED room mirror capable of adjusting the reflectance according to the present invention shown in FIG. 3.

먼저, 광센서(10)를 통해 OLED 미러(30)에 비치는 햇빛의 발기나 후방차량에 의한 전조등의 밝기를 측정한다(S10). First, the brightness of the headlamps caused by the erection of the sunlight or the rear vehicle reflected on the OLED mirror 30 through the optical sensor 10 is measured (S10).

이와 같이 측정된 광센서(10)의 값에 의해 반사율을 조절하기 위한 OLED 미러(30)의 구동값을 결정한다(S20). The driving value of the OLED mirror 30 for adjusting the reflectance is determined by the value of the optical sensor 10 measured as described above (S20).

즉, OLED 미러(30)에 비치는 햇빛이나 전조등의 밝기에 따라 OLED 미러(30)의 유기발광층(36)으로 인가되는 전류나 전압을 조절하여 발광밝기를 조절할 구동전류나 구동전압을 결정한다. That is, the driving current or the driving voltage to adjust the emission brightness is determined by adjusting the current or voltage applied to the organic light emitting layer 36 of the OLED mirror 30 according to the brightness of sunlight or the headlights reflected on the OLED mirror 30.

이렇게 결정된 OLED 미러(30)의 구동값에 따라 OLED 미러(30)를 구동하게 되 는 1㎲의 빠른 동작속도로 양전극(32)에서 주입되는 정공과 음전극(38)에서 인가되는 전자에 의해 OLED 미러(30)의 유기발광층(36)에서 발광되는 발광 빛과 OLED 미러(30)에 반사되는 햇빛이나 전조등의 빛들간의 조합에 의해 OLED 미러(30)에 반사되는 빛의 강도를 조절하게 된다(S20). The OLED mirror is formed by holes injected from the positive electrode 32 and electrons applied from the negative electrode 38 at a fast operating speed of 1 kHz that drives the OLED mirror 30 according to the determined driving value of the OLED mirror 30. The intensity of the light reflected by the OLED mirror 30 is controlled by a combination of the light emitted from the organic light emitting layer 36 of the 30 and the light of the sunlight or the headlamp reflected by the OLED mirror 30 (S20). ).

이때, OLED 미러(30)에 비치는 햇빛이나 전조등의 밝기가 밝을 경우에는 OLED 미러(30)의 발광밝기를 밝게 조절하고 OLED 미러(30)에 비치는 햇빛이나 전조등의 밝기가 어두울 경우에는 OLED 미러(30)의 발광밝기를 어둡게 조절한다. At this time, when the brightness of the sunlight or the headlights reflected on the OLED mirror 30 is bright, the light emission brightness of the OLED mirror 30 is adjusted brightly, and when the brightness of the sunlight or the headlights reflected on the OLED mirror 30 is dark, the OLED mirror 30 Adjust the brightness of the light.

상기한 바와 같이 본 발명은 야간 운전시 후방차량의 전조등이나 주간의 햇빛에 의해 룸미러에 비춰지는 광도를 감지하여 감지된 광도의 크기에 따라 OLED 소자의 밝기를 조절하여 눈부심을 줄일 수 있는 이점이 있다. As described above, the present invention has the advantage of reducing the glare by adjusting the brightness of the OLED device according to the detected intensity of light by detecting the light emitted to the room mirror by the headlights or daytime sunlight of the rear vehicle during night driving have.

또한, OLED 미러의 제조공정이 단순하여 간단하게 OLED 미러를 제조할 수 있을 뿐만 아니라 빠른 동작속도로 인해 눈부심을 방지하여 시력을 보호하며 운전의 안전성을 도모할 수 있는 이점이 있다.
In addition, the OLED mirror manufacturing process is not only simple to manufacture the OLED mirror, but also has the advantage of preventing the glare due to the fast operating speed to protect eyesight and to improve the safety of operation.
