본 고안은 두부탑재형 디스플레이장치(Dead Mounted Display)에 관한 것으로, 특히 두 광원에서 방출되는 광량의 차이를 비교, 조절하여 사람의 양쪽 눈으로 입사되는 화상의 밝기를 동일하게 할 수 있는 두부탑재형 디스플레이장치에 관한 것이다.The present invention relates to a head-mounted display device (Dead Mounted Display), in particular the head-mounted type that can equalize the brightness of the image incident to both eyes of the human by comparing and adjusting the difference in the amount of light emitted from the two light sources It relates to a display device.
종래의 두부탑재형 디스플레이장치는, 제1도에 나타낸 바와 같이, 화상신호를 공급하는 화상신호공급부(1)와, 인가되는 구동전압의 크기에 따라 광량이 다른 광선을 방출하는 제1광원(3) 및 제2광원(4)와, 상기 제1광원(3) 또는 제2광원(4)으로부터의 광선을 입력받아 상기 화상신호공급부(1)의 화상신호에 따른 화상을 디스플레이하는 제1화상표시부(5) 및 제2화상표시부(6)와, 상기 제1화상표시부(5) 또는 제2화상표시부(6)가 디스플레이한 화상을 확대하는 제1확대경(7) 및 제2확대경(8)과, 상기 제1광원(3) 및 제2광원(4)에 고정된 크기의 구동전압을 인가하는 전원공급부(2)를 포함하여 구성된다. 이때, 제1화상표시부(5) 및 제2화상표시부(6)는 액정표시소자(Liqued Crystal Display)로 각각 구현되며, 제1확대경(7) 및 제2확대경(8)은 루뻬(lupe)경으로 각각 구현된다.In the conventional head mounted display device, as shown in FIG. 1, an image signal supply unit 1 for supplying an image signal and a first light source 3 for emitting light having a different amount of light depending on the magnitude of a driving voltage applied thereto. ) And a first image display unit for receiving a light beam from the second light source 4 and the first light source 3 or the second light source 4 and displaying an image according to the image signal of the image signal supply unit 1. (5) and the second image display unit 6, the first magnifying glass 7 and the second magnifying glass 8 for enlarging the image displayed by the first image display unit 5 or the second image display unit 6; And a power supply unit 2 for applying a driving voltage having a fixed size to the first light source 3 and the second light source 4. In this case, the first image display unit 5 and the second image display unit 6 are each implemented as a liquid crystal display, and the first magnification 7 and the second magnification 8 are loupe diameters. Each is implemented as
이와 같이 구성된 종래의 두부탑재형 디스플레이장치의 작용을 살펴보면, 먼저 인가된 구동전압의 크기에 따라 광량이 다른 광선을 방출하도록 된 우측의 제1광원(3) 및 좌측의 제2광원(4)이 전원공급부(2)로부터 각각 일정한 크기의 구동전압을 공급받아 광선을 각각 방출하면 이 광선은 제1광원(3)과 대응되도록 설치된 제1화상 표시부(5) 및 제2광원(4)과 대응되도록 설치된 제2화상표시부(6)에 각각 입사되며, 이와 같이 광선을 입사받는 제1화상표시부(5) 및 제2화상표시부(6)는 화상신호를 공급받는 화상신호공급부(1)로 부터의 화상신호에 따른 화상을 각각 디스플레이한다.Referring to the operation of the conventional head-mounted display device configured as described above, the first light source 3 on the right side and the second light source 4 on the left side are configured to emit light with different amounts of light depending on the magnitude of the driving voltage applied. When each of the light sources receives a predetermined driving voltage from the power supply unit 2 and emits light beams, the light beams correspond to the first image display unit 5 and the second light source 4 installed to correspond to the first light source 3. The first image display unit 5 and the second image display unit 6 respectively incident on the second image display unit 6 provided therein and receiving light rays as described above are provided from the image signal supply unit 1 receiving the image signal. Each image according to the signal is displayed.
그리고, 제1화상표시부(5)와 제2화상표시부(6)가 디스플레이한 화상은 제1확대경(7) 및 제2확대경(8)에 의해 확대되어 사람의 왼쪽눈(이하, 좌안이라 한다) 및 오른쪽눈(이하, 우안이라 한다)에 각각 입사된다.The image displayed by the first image display unit 5 and the second image display unit 6 is enlarged by the first magnifier 7 and the second magnifier 8 to be referred to as the left eye of the person (hereinafter referred to as the left eye). And right eye (hereinafter, referred to as right eye).
사람은 입사된 두 화상이 동일한 정보를 갖는 것이라면 결과적으로 동일한 화면을 느끼게 되고, 입사된 두 화상이 분할된 입체화상이라면 결과적으로 조합된 입체화상을 느끼게 된다.If the two incident images have the same information, a person may feel the same screen, and if the two incident images are the divided three-dimensional images, the result is a combined three-dimensional image.
그리고 이때 사람의 좌안과 우안에 입사되는 상기 두 화상의 밝기는 같아야 하며, 만약 두 화상의 밝기가 다르면 사람이 눈의 피로를 느끼게 되는 등의 부작용이 발생한다.At this time, the brightness of the two images incident on the left and right eyes of the person should be the same, and if the brightness of the two images is different, side effects such as a person feeling eye fatigue occur.
두 화상의 밝기가 서로 다르게 되는 이유는 제1광원(3)과 제2광원(4)에서 방출되는 두 광선의 광량이 서로 다르기 때문이며, 또 그 두 광선의 광량이 다르게 되는 이유는 상기 제1광원(3)과 제2광원(4) 자체에 문제가 있기 때문이다.The brightness of the two images is different from each other because the light quantity of the two light rays emitted from the first light source 3 and the second light source 4 is different from each other, and the reason that the light quantity of the two light rays is different from the first light source is different. This is because there is a problem with (3) and the second light source (4) itself.
이와 같이, 종래에는 인가전압의 크가에 따라 광량이 다른 광선을 방출하는 제1광원에서 동일한 양의 광선이 방출되도록 하기 위해서 전원공급부가 그 제1광원과 제2광원에 각각 동일한 크기의 구동전압을 인가하더라도 제1광원 및 제2광원 자체에서 발생한 차이에 의해, 가령 제1광원의 수명과 제2광원의 수명이 다르다거나, 서로의 사용조건이 다르다거나, 또는 아예 제조시부터 두 광원 자체에 차이가 있었다든가에 의해, 두 광원에서 서로 다른 광량을 갖는 광선이 방출되어 결국 사람의 좌안 및 우안으로 입사되는 화상의 밝기가 달라지기 때문에 사람의 눈이 쉽게 피로해질 뿐만 아니라, 경우에 따라서는 사용자가 화상의 화질이 저하된 것으로 오인할 수 있다는 문제점이 있다.As such, in the related art, in order to emit the same amount of light from the first light source that emits light with different amounts of light depending on the magnitude of the applied voltage, the power supply unit has a driving voltage having the same magnitude to the first light source and the second light source, respectively. Even if is applied, the lifespan of the first light source and the second light source itself is different, for example, the lifespan of the first light source and the second light source is different, the conditions of use of each other are different, or the two light sources themselves are not manufactured at all. The difference between the two light sources results in the emission of light with different amounts of light, and thus the brightness of the image which is incident on the left and right eyes of the person is different, which not only makes the human eye easily tired, but also sometimes the user. There is a problem that can be mistaken that the image quality is degraded.
따라서, 본 고안의 목적은, 앞서 열거한 이유에 의해 두 광원에서 방출되는 광량에 차이가 발생하더라도 자동적으로 그 광량의 차이를 보상해 줄 수 있는 두부탑재형 디스플레이장치를 제공하는 것이다.Accordingly, an object of the present invention is to provide a head mounted display device that can automatically compensate for the difference in the amount of light even if a difference occurs in the amount of light emitted from the two light sources for the reasons listed above.
상기 목적에 따른 본 고안의 두부탑재형 디스플레이장치는, 화상신호를 공급하는 화상신호공급부와, 인가되는 구동전압의 크기에 따라 광량이 다른 관선을 방출하는 제1광원 및 제2광원과, 상기 제1광원 또는 제2광원으로부터의 광선을 입력받아 상기 화상신호공급부의 화상신호에 따른 화상을 디스플레이하는 제1화상표시부 및 제2화상표시부와, 상기 제1화상표시부 또는 제2화상표시부가 디스플레이한 화상을 확대하는 제1확대경 및 제2확대경과, 상기 제1광원 또는 제2광원에서 출력되는 광선의 광량을 검출하는 제1광센서 및 제2광센서와, 상기 제1광센서 또는 제2광센서가 검출한 광선의 광량에 따라 조절된 구동전압을 상기 제1광원 및 제2광원에 공급하는 전원조절공급부로 구성된다.According to the above object, the head mounted display device of the present invention includes an image signal supply unit for supplying an image signal, a first light source and a second light source for emitting a conduit with a different amount of light depending on the magnitude of a driving voltage applied thereto; A first image display unit and a second image display unit which receive light rays from one light source or a second light source and display an image according to the image signal of the image signal supply unit; and an image displayed by the first image display unit or the second image display unit A first magnification mirror and a second magnification mirror for enlarging a light source, a first optical sensor and a second optical sensor for detecting an amount of light emitted from the first light source or a second light source, and the first optical sensor or a second optical sensor And a power regulation supply unit for supplying a driving voltage adjusted according to the light amount of the detected light beam to the first light source and the second light source.
이와 같이 구성된 본 고안의 작용을 하나의 구체적 실시예를 나타낸 제2도 및 제3도를 참조하여 상세히 설명하면 다음과 같다.The operation of the present invention configured as described above will be described in detail with reference to FIGS. 2 and 3 showing one specific embodiment.
제1광센서(15-1)는 제1광원(13)과 마주보도록 제1화상표시부(15)에 그리고, 제2광센서(16-1)는 제2광원(14)과 마주보도록 제2화상표시부(16)에 각각 설치되어 있으므로 각각 해당하는 광원에서 방출되는 광선을 감지할 수 있는데, 즉 제1광센서(15-1)는 제1광원(13)에서 방출되는 광선의 광량을 측정하고 그 측정된 광량에 따른 검출신호(이하, 제1검출신호라 한다)를 전원조절공급부(12)로 보낸다.The first light sensor 15-1 faces the first image display unit 15 so as to face the first light source 13, and the second light sensor 16-1 faces the second light source 14. Since each of the image display unit 16 is installed in each of the light sources emitted from the corresponding light source can be detected, that is, the first light sensor 15-1 measures the amount of light emitted from the first light source 13 A detection signal (hereinafter referred to as a first detection signal) corresponding to the measured light amount is sent to the power control supply unit 12.
아울러, 제2광센서(16-1)도 제2광원(14)에 방출되는 광선의 광량을 측정하고 그 측정된 광량에 따른 검출신호(이하, 제2검출신호라 한다)를 역시 전원조절공급부(12)로 보낸다.In addition, the second optical sensor 16-1 also measures the amount of light emitted from the second light source 14, and also detects a detection signal (hereinafter referred to as a second detection signal) according to the measured amount of power. Send to (12).
이와 같이 제1광센서(15-1)로부터 제1검출신호 그리고 제2광센서(16-1)로부터 제2검출신호를 입력받은 전원조절공급부(12)는 제1증폭기(12-1)와 제2증폭기(12-2)를 이용하여 그 제1검출신호 및 제2검출신호를 각각 소정의 크기로 증폭한 다음, 제1비교기(12-3)에서 상기 제1증폭기(12-1)에 의해 증폭된 제1검출신호와 설정된 기준전압이 서로 비교되고 그 비교결과에 따른 비교신호가 제1비교기(12-3)에서 출력된다.As such, the power supply control unit 12 receiving the first detection signal from the first optical sensor 15-1 and the second detection signal from the second optical sensor 16-1 is connected to the first amplifier 12-1. Using the second amplifier 12-2, the first detection signal and the second detection signal are amplified to a predetermined size, respectively, and then the first comparator 12-3 is used to transmit the first amplifier 12-1. The first detection signal amplified by the first reference signal and the set reference voltage are compared with each other, and a comparison signal according to the comparison result is output from the first comparator 12-3.
역시 상기 제2증폭기(12-2)에 의해 증폭된 제2검출신호도 제2비교기(12-4)에서 외부에서 입력된 상기 기준전압과 비교되고 그 비교결과에 따른 비교신호가 제2비교기(12-4)에서 출력된다.Also, the second detection signal amplified by the second amplifier 12-2 is also compared with the reference voltage input from the second comparator 12-4 externally, and the comparison signal according to the comparison result is compared with the second comparator ( 12-4).
그러면 제1전원공급부(12-5)는 그 제1비교기(12-3)에서 출력된 비교신호를 입력받아 제1광원(13)를 구동하고, 제2전원공급부(12-6)도 제2비교기(12-4)에서 출력된 비교신호를 입력받아 제2광원(14)를 구동한다.Then, the first power supply unit 12-5 receives the comparison signal output from the first comparator 12-3 to drive the first light source 13, and the second power supply unit 12-6 also receives the second signal. The second light source 14 is driven by receiving the comparison signal output from the comparator 12-4.
즉, 제1검출신호와 기준신호를 비교하여 얻은 값과, 상기 제2검출신호와 기준신호를 비교하여 얻는 값이 동일하면, 제1광센서(15-1)에서 방출되는 광선의 광량과 제2광센서(16-1)에서 방출되는 광선의 광량이 동일한 것으로 되어 결국 제1광원(13) 및 제2광원(14)에는 동일한 구동전압이 인가된다.That is, when the value obtained by comparing the first detection signal and the reference signal and the value obtained by comparing the second detection signal and the reference signal are the same, the amount of light emitted from the first optical sensor 15-1 and the first signal The amount of light emitted from the two light sensors 16-1 is the same, and thus, the same driving voltage is applied to the first light source 13 and the second light source 14.
그러나 반대로 제1검출신호와 기준신호를 비교하여 얻은 값과, 상기 제2검출신호와 기준신호를 비교하여 얻은 값이 동일하지 않으면, 제1광센서(15-1)에서 방출되는 광선의 광량과 제2광센서(16-1)에서 방출되는 광선의 광량은 동일하지 않은 것이 되므로 결국 제1광원(13)과 제2광원(14)에 인가되는 구동전압의 크기가 조절된다.On the contrary, if the value obtained by comparing the first detection signal and the reference signal and the value obtained by comparing the second detection signal and the reference signal are not the same, the amount of light emitted from the first optical sensor 15-1 Since the amount of light emitted from the second light sensor 16-1 is not the same, the magnitude of the driving voltage applied to the first light source 13 and the second light source 14 is adjusted.
이와 같이 전원조절공급부(12)는 1개의 기준전압을 이용하여 제1검출신호와 제2검출신호의 크기를 비교하고 그 크기의 동일여부에 따라 제1광원과 제2광원에 인가되는 구동전압의 크기를 조절하여 구동전압을 공급하므로 두 광원에서 방출되는 광선의 광량의 차이를 보상할 수 있다.In this way, the power supply control unit 12 compares the magnitudes of the first detection signal and the second detection signal using one reference voltage, and determines whether the magnitudes of the driving voltages applied to the first and second light sources are equal. Since the driving voltage is adjusted by adjusting the size, the difference in the amount of light emitted from the two light sources can be compensated.
지금가지 설명한 바와 같이, 본 고안은 제1광센서와 제2광센서를 이용하여 두 광원에서 방출되는 광선의 광량을 측정하고 전원조절공급부가 그 제1광센서 및 제2광센서가 측정한 두 광량을 기준전압과 비교하여 그 비교 결과에 따라 제1광원과 제2광원에 인가되는 구동전압의 크기를 조절하여 공급해 주기 때문에 항상 동일한 밝기의 화상이 출력되므로 사용자는 눈의 피로를 느끼지 않게 되며 그리고 화상의 질이 저하되었다는 오인도 하지 않는다는 효과를 갖는다.As described above, the present invention measures the amount of light emitted from the two light sources by using the first light sensor and the second light sensor, and the power supply is measured by the first light sensor and the second light sensor. Since the amount of light is compared with the reference voltage and the driving voltage applied to the first light source and the second light source is adjusted and supplied according to the comparison result, an image of the same brightness is always output, so that the user does not feel eye fatigue, and It has the effect of not misunderstanding that the image quality is degraded.
