3 : 관찰창 3a : 결상면(結像面)3: observation window 3a: imaging surface
4 : 확대렌즈4: magnifying lens
본 고안은 전자기기의 표시장치에 관한 것으로서, 특히 LCD(liquid crystal display) 등의 편판형 표시소자의 사용에 적합한 표시장치에 관한 것이다.The present invention relates to a display device of an electronic device, and more particularly, to a display device suitable for use of a flat plate display device such as a liquid crystal display (LCD).
음향기기나 영상기기 등 각종의 전자기기에는 그 작동 상태를 표시하기 위해 각종의 인디케이터(indicator)나 표시장치 등이 설치된다.Various indicators, display devices, and the like are installed in various electronic apparatuses such as sound apparatuses and video apparatuses to display the operation states thereof.
이러한 표시장치는 주로 기기의 프론트 패널(front panel) 등에 설치되며, 사용되는 표시소자로는 LCD나 형공표시관 등 편판형 소자가 널리 쓰이고 있다.Such a display device is mainly installed in a front panel of a device, and a plate-like device such as an LCD or a mold display tube is widely used as a display device.
이와 같은 표시장치의 일례를 제1도에 보인바, 이것은 프론트 패널 등 기기의 케이싱(casing : 14)에 유리 등의 투명기재로 된 관찰창(13)을 설치하여 회로기판(12)에 설치된 표시소자(11)가 이 관찰창(13)을 통하여 판독되도록 되어 있다.An example of such a display device is shown in FIG. 1, which is a display provided on a circuit board 12 by providing an observation window 13 made of a transparent substrate such as glass in a casing 14 of a device such as a front panel. The element 11 is intended to be read through this observation window 13.
그런데 이 표시장치는 사용자가 기기로부터 충분히 이격된 위치에서도 판독이 가능해야 하는바, 종래의 표시장치에 있어서는 표시소자(11)의 크기로서 이 요구를 충족시켰다. 따라서 표시소자(11)가 대형화되고, 이에 따라 회로기판(12)의 큰 영역을 점유하므로 회로구성에 많은 난점이 있으며 표시소자(11)의 가격이 상승하는 문제가 발생되었다. 또 유리 등 취약한 기재로 제작되는 표시소자는 크기가 커짐에 따라 상대적으로 강도가 낮아지므로 이에 대해 적절한 지지등 추가적인 배려도 필요하였다.However, the display device must be able to be read even at a position sufficiently spaced apart from the apparatus by the user. In the conventional display device, the display element 11 satisfies this requirement. Therefore, since the display element 11 is enlarged and thus occupies a large area of the circuit board 12, there are many difficulties in the circuit configuration and the price of the display element 11 increases. In addition, display devices made of fragile substrates, such as glass, are relatively low in strength as their size increases, requiring additional consideration such as proper support.
이와 같은 종래의 문제점을 감안하여 본 고안은 소형의 표시소자를 사용하면서도 원기렝서 판독이 가능한 전자기기의 표시장치를 제공하는 것을 목적으로 한다.In view of such a conventional problem, an object of the present invention is to provide a display device of an electronic device capable of reading a refresher while using a small display element.
이와 같은 목적을 달성하기 위해 본 고안은, 표시소자에 표시되는 화상을 관찰창을 통해 인식하도록 된 전자기기의 표시장치에 있어서, 상기한 관찰창이 반투명처리된 결상면을 형성하고, 상기한 표시소자와 관찰창 사이에 그 표시소자의 화상을 확대하여 상기한 관찰창의 결상면에 투영하는 확대렌즈를 설치하고, 상기한 표시소자와 확대렌즈 사이의 측방에 그 표시소자를 조명하는 램프를 설치하여 구성하는 것을 그 특징으로 한다.In order to achieve the above object, the present invention provides a display device for an electronic device that recognizes an image displayed on a display device through an observation window, wherein the observation window forms an image transmissive surface translucently processed, and the display device. A magnification lens for enlarging the image of the display element and projecting the image on the image forming surface of the observation window between the and the observation window, and a lamp for illuminating the display element on the side between the display element and the magnification lens. It is characterized by that.
이러한 본 고안의 바람직한 실시예를 도면 제2도를 참조하여 상세하게 설명하면 다음과 같다.When described in detail with reference to Figure 2 the preferred embodiment of the present invention as follows.
제2도에 도시된 본 고안 표시장치는 회로기판(2)에 배치 및 접속된 표시소자(1; 특히 LCD 패널)와, 지지부(2a)를 통해 표시소자(1)와 소정간격으로 이격되게 배치된 확대렌즈(4)와, 결상면(3a)을 가지고 있고 이 결상면(3a)이 확대렌즈(4)와 소정간격으로 이격되어 케이싱(5)에 지지되는 관찰창(3), 그리고 표시소자(1)를 측방에서 조명하는 램프(lamp : 6)로 구성되어 있다.The display device of the present invention shown in FIG. 2 is arranged to be spaced apart from the display element 1 at a predetermined interval through a display element 1 (especially an LCD panel) and a support part 2a arranged and connected to the circuit board 2. An observation window 3 having a magnified lens 4 and an imaging surface 3a, the imaging surface 3a being spaced apart from the magnifying lens 4 at a predetermined interval and supported by the casing 5, and a display element. It consists of a lamp (lamp 6) which illuminates (1) from the side.
여기서 표시소자(1)의 확대렌즈(4)와 관찰창(3)의 위치관계는, 확대렌즈(4)의 후촛점거리(back focal length)에 그 표시소자(1)가 위치되고, 전촛점거리(front focal length)에는 관찰창(3)의 결상면(3a)이 위치되게 하는 것이 바람직하다. 또한 관찰창(3)의 결상면(3a)은 거기에 투영되는 영상이 사용자의 눈에 잘 보이도록 도막(塗膜) 또는 연마 등의 방법으로 반투명처리하여 구성한다.Here, the positional relationship between the magnification lens 4 and the observation window 3 of the display element 1 is that the display element 1 is located at the back focal length of the magnification lens 4, It is preferable to position the imaging surface 3a of the observation window 3 at the front focal length. In addition, the image formation surface 3a of the observation window 3 is comprised by the translucent process by methods, such as a coating film or grinding | polishing, so that the image projected thereon can be seen by a user's eye well.
상기한 구성의 본 고안 표시장치의 작동은 다음과 같다.Operation of the present invention display device of the above configuration is as follows.
표시소자(1)에 표시되는 세그먼트(segment) 정보 형태의 화상은 확대렌즈(4)에 의한 상으로서 예를 들면 도립허상(倒立虛像)으로 결상되도록 관찰창(3)의 결상면(3a)에 투영된다. 따라서 사용자는 그 관찰창(3)의 결상면(3a)에 확대투영된 화상을 보고 그 표시내용을 쉽게 그리고 분명하게 인식할 수 있는 것이다. 한편, 램프(6)가 표시소자(1)를 밝게 조명하므로 광찰창(3)의 결상면(3a)에 확대투영되는 화상의 밝기를 높여 그 인식도를 높이는 효과가 제공되는 것이다.An image in the form of segment information displayed on the display element 1 is an image by the magnification lens 4 and is formed on the imaging surface 3a of the observation window 3 so as to form an image, for example, as an inverted image. Projected. Therefore, the user can easily and clearly recognize the display contents by viewing the image projected on the image formation surface 3a of the observation window 3. On the other hand, since the lamp 6 illuminates the display device 1 brightly, the effect of increasing the brightness of the image projected on the image plane 3a of the light reflection window 3 is increased, thereby improving the recognition.
상기와 바와 같이, 본 고안에 따른 표시장치는 소형의 표시소자로 충분한 크기의 화상 정보를 제공하는 것이 가능하여 기기 내부의 회로기판 등의 효율적 설계 및 배치가 수월해지고, 특히 결상면을 갖는 관찰창에 확대투영되는 화상을 인식하게 하므로써 그 화상의 시야범위를 넓게 확보하고 또한 조명을 사용함으로써 양호한 화상 및 인식도 높은 화상정보를 제공할 수 있고 이로써 사용자의 편리를 크게 향상시킬 수 있는 효과를 제공하는 것이다.As described above, the display device according to the present invention is capable of providing image information of a sufficient size with a small display element, thereby facilitating efficient design and arrangement of circuit boards and the like inside the device, and in particular, an observation window having an image plane. By recognizing the image to be projected on the screen, it is possible to secure a wide field of view of the image and to provide good image and high image information by using illumination, thereby providing an effect that can greatly improve the user's convenience. .
