본 고안은 액정 표시장치를 이용한 색구현 장치에 관한 것으로, 특히 액정 셀에 투과되는 빛을 회전하는 편광판으로 조절하여 다양한 색깔의 빛을 이용하기에 적당하도록한 색구현 장치에 관한 것이다.The present invention relates to a color realization device using a liquid crystal display, and more particularly, to a color realization device that is suitable to use various colors of light by adjusting the light transmitted through the liquid crystal cell with a rotating polarizing plate.

일반적으로 액정 표시소자는 상부 및 하부 패널에 액정을 주입하고 그 상하부 패널을 합착한 후 편광판 사이에 끼워 액정층에 전압을 인가하여 사용한다.In general, a liquid crystal display is used by injecting a liquid crystal into the upper and lower panels, bonding the upper and lower panels, and sandwiching between polarizing plates to apply a voltage to the liquid crystal layer.

이때 인가전압에 의해 액정 분자는 전계 방향으로 전계되고 전압을 제거하면 다시 원래의 나선형 배열로 돌아온다.At this time, the liquid crystal molecules are electric fields in the electric field direction by the applied voltage, and when the voltage is removed, the liquid crystal molecules are returned to the original spiral array.

즉 90°틀어진 부분에서는 빛이 통과하고 전압이 가해진 부분에서는 액정이 전계의 방향으로 배열되어 빛이 통과하지 못하므로 원하는 데이터를 표시할 수 있다.That is, since the light passes through the 90 ° portion and the liquid crystal is arranged in the direction of the electric field in the portion where the voltage is applied, the light does not pass and thus display the desired data.

제1도는 일반적인 액정 셀 구조도로서, 이에 도시한 바와같이 빛을 투과시킬수 있는 절연 기판등으로 형성된 상부 패널(1)과 하부판넬(2)의 전계에 따라 배열 방향이 변화하여 빛의 통과 여부를 결정하는 액정(4)을 포함하여 씰수지(5)에 의해 합착되고, 상기 상하부 판넬(1)(2)의 하부와 상부에 액정(4)의 배열을 정해 주는 배향막(3)이 형성되며, 상기 상하부 패널(1)(2)상하부에 편광판(6)이 각기 부착되며 상기 하부판넬(2)의 편광판(6)에 빛을 투사하는 백라이트로 구성한다.FIG. 1 is a general structure of a liquid crystal cell. As shown in FIG. 1, an arrangement direction is changed according to an electric field of an upper panel 1 and a lower panel 2 formed of an insulating substrate that can transmit light to determine whether light passes. The liquid crystal 4 is bonded to each other by the seal resin 5, and an alignment layer 3 is formed on the lower and upper portions of the upper and lower panels 1 and 2 to determine the arrangement of the liquid crystals 4. The upper and lower panels 1 and 2 are attached to upper and lower polarizing plates 6, respectively, and consist of a backlight for projecting light onto the polarizing plates 6 of the lower panel 2.

상기와 같이 구성한 액정 표시소자를 이용한 색구현 장치의 동작 과정 및 문제점을 설명하면 다음과 같다.Referring to the operation process and problems of the color implementation device using the liquid crystal display device configured as described above are as follows.

액정 셀에 전압을 인가하면 액정(4)의 전계의 방향에 따라 배열되어 빛의 투과여부를 결정하고 전압을 차단하면 원래방향으로 배열된다. 이때 편광판(6)은 부착 각도에 따라 전압을 인가하지 않을 시에 백라이트 빛을 투과 시키거나 흡수시키는 역할을 하여 전압인가시와 반대의 현상을 나타내어 측백의 빛을 표현한다.When voltage is applied to the liquid crystal cell, the liquid crystal 4 is arranged according to the direction of the electric field to determine whether light is transmitted, and when the voltage is blocked, the voltage is arranged in the original direction. At this time, the polarizing plate 6 transmits or absorbs the backlight light when no voltage is applied according to the attachment angle, thereby exhibiting a phenomenon opposite to that of voltage application, thereby expressing light of white matter.

한편 조명기기는 전압인가에 따라 전류를 흐르게 하여 전기적 특성을 광학적 특성으로 변화시키며 백열등과 형광 등에 여러 색깔을 주기 위해서는 표면이나 외부에 착색하여 원하는 색을 표현할 수 있다.On the other hand, the lighting device changes the electrical characteristics to the optical characteristics by flowing a current according to the application of voltage, and in order to give various colors to incandescent lamps and fluorescent lamps, they can be colored on the surface or the outside to express a desired color.

이상에서 설명한 바와같이 종래의 색구현 장치중 액정 표시소자는 편광측을 고정시켜 사용하므로 원하는 단색의 색상만을 선택하여 사용하고 색구현 장치의 성능을 저하시키며, 또한 조명기기도 원하는 색상을 만들고자할 때 형광등, 백열 등의 표면이나 외부 커버에 착색하여야 하므로 조명기기의 성능을 저하시키는 문제점이 있었다.As described above, since the liquid crystal display device of the conventional color implementer is used by fixing the polarization side, it is necessary to select and use only a single color of the desired color, and deteriorate the performance of the color implementer. Since it should be colored on the surface or the outer cover, such as a fluorescent lamp, incandescent, there was a problem of deteriorating the performance of the lighting equipment.

본 고안은 상기와 같은 종래의 문제점을 감안하여, 회전 장치로 편광판의 회전을 제어하여 빛의 파장을 조절함으로써 특별한 착색방법 없이 원하는 여러 가지 색을 표현하고자 한다.The present invention, in view of the conventional problems as described above, to control the rotation of the polarizing plate with a rotating device to adjust the wavelength of the light to express a variety of colors without a special coloring method.

제2도는 액정 표시소자를 이용한 색구현 장치도로서, 이에 도시한 바와같이 전압 인가에 따라 전계의 방향으로 배열되는 액정을 포함하여 빛의 투과 여부를 결정하는 액정 셀(9)과, 그 액정 셀(9)에 빛을 인가하는 광원부(7)와, 빛의 파장 조절을 위해 제어하는 제어부(12)와, 그 제어부(12)의 제어신호에 의해 상기 광조절부(8)를 회전시키는 회전장치(11)와, 그 회전장치(11)와 상기 광조절부(8)을 접속시키는 접속부(10)로 구성한다.FIG. 2 is a diagram of a color realization device using a liquid crystal display device. As shown therein, a liquid crystal cell 9 including liquid crystals arranged in the direction of an electric field in response to voltage application to determine whether light is transmitted therethrough, and the liquid crystal cell A light source unit 7 for applying light to the light source 9, a control unit 12 for controlling the wavelength of light, and a rotating device for rotating the light control unit 8 by a control signal of the control unit 12. And a connecting portion 10 for connecting the rotary device 11 and the light adjusting portion 8 to each other.

상기와 같이 구성한 본 고안의 액정 표시소자를 이용한 색구현 장치의 동작과정 및 작용효과를 상세히 설명하면 다음과 같다.Referring to the operation process and operation effect of the color implementation device using the liquid crystal display device of the present invention configured as described above in detail as follows.

전압이 인가되면 광원부(7)는 그 전압에 의해 전기적 에너지를 광학 에너지로 변화시켜 빛을 발생하여 광조절부(8)의 편광판(6)에 인가하고, 이 빛은 편광판(6)을 통과하면서 그 편광판(6)에 맞는 파장만 통과한다.When a voltage is applied, the light source unit 7 converts electrical energy into optical energy by the voltage, generates light and applies the light to the polarizing plate 6 of the light control unit 8, and the light passes through the polarizing plate 6. Only the wavelength matching the polarizing plate 6 passes.

이때 액정 셀(9)에 전압이 인가되지 않을 경우 액정이 빛을 통과시키는 형태로 액정 셀을 구성하면 액정을 통한 파장이 마지막 편광판(6')의 회전각도에 따라 여러 가지 색에 맞는 파장을 내보냄으로 인하여 사용자가 원하는 다양한 색을 표현할 수 있으므로 제어부(12)는 사용자가 원하는 색깔에 상응하는 파장의 제어신호를 회전장치(11)에 인가하고, 그 회전장치(11)는 제어신호 및 수동신호로 접속부(10)를 통해 광조절부(8)의 상기 편광판(6)을 액정 셀(9)을 통과한 빛에서 원하는 파장만 통과시켜 색을 표현한다.In this case, when no voltage is applied to the liquid crystal cell 9, the liquid crystal cell is configured to pass light, and the wavelength through the liquid crystal emits wavelengths suitable for various colors according to the rotation angle of the last polarizing plate 6 ′. Therefore, since the user can express various colors desired by the user, the control unit 12 applies a control signal having a wavelength corresponding to the color desired by the user to the rotating device 11, and the rotating device 11 is a control signal and a manual signal. The polarizing plate 6 of the light control unit 8 through the connection portion 10 passes through the liquid crystal cell 9 and passes only a desired wavelength to express colors.

한편 일반적인 스탠드에 있어서 빛을 방출하는 광원부 밑에 액정 셀을 장착하고 사용자가 원하는 색깔의 파장을 선택하여 편광판을 회전시켜 파장을 조절하면 별도의 착색 과정없이 다양한 색의 신호를 얻을수 있다.Meanwhile, in a general stand, a liquid crystal cell is mounted under a light emitting part that emits light, and a user selects a wavelength of a desired color and rotates a polarizing plate to adjust the wavelength to obtain signals of various colors without a separate coloring process.

이상에서 상세히 설명한 바와같이 본 고안의 색구현 장치는 기존에 사용되고 있는 모든 조명기기에 액정 셀을 장착하여 종래의 착색 과정없이 편광판을 회전시켜 원하는 색에 상응하는 파장의 투과를 제어함으로써 다양한 색을 구현할수 있어 조명기기의 성능을 향상시키는 효과가 있다.As described in detail above, the color realization device of the present invention implements various colors by mounting a liquid crystal cell to all the lighting devices that are used in the past and controlling the transmission of a wavelength corresponding to a desired color by rotating a polarizing plate without a conventional coloring process. It can have the effect of improving the performance of the lighting equipment.
