본 고안은 액정 디스플레이(LCD ; Liquid Crystal Display)의 백라이트(Back Light)구조, 보다 상세하게는 액정 디스플레이의 표시부 판넬을 통하여 표출되는 특정부위의 문자 및 형상을 현저하게 강조할 수 있는 액정 디스플레이의 백라이트 구조에 관한 것이다.The present invention provides a backlight structure of a liquid crystal display (LCD), and more particularly, a backlight of a liquid crystal display capable of remarkably emphasizing characters and shapes of a specific portion displayed through a display panel of a liquid crystal display. It's about structure.
일반적으로 각종의 전자제품, 특히 가전제품은 그 작동 과정이나 상태를 발광 표시장치를 통하여 표출시킴으로써, 사용자로 하여금 용이하게 식별할 수 있도록 한 방법이 보편화되고 있다.In general, a variety of electronic products, particularly home appliances, by expressing the operation process or state through the light emitting display device, a method that makes it easy for the user to identify easily.
종래의 발광 표시장치는 발광 다이오드(LED ; Light Emitting Diode) 또는 7-새그먼트( segment) 등으로 제작한 후, 발광부의 색상을 서로 달리 구성함으로서 특정한 부위를 강조하여 표출하였다.The conventional light emitting display device is manufactured by using a light emitting diode (LED) or a 7-segment (segment), and then expresses a specific area by emphasizing the color of the light emitting unit.
그러나, 상기 종래의 표시 장치는 제작과정에서 많은 공수가 필요한 반면 상대적으로 불량률이 많은 결점이 있었으므로, 상기 LED 방법에 비해 제작이 손쉽고 불량률이 적은 액정 디스플레이(LED)를 선호하는 추세이다.However, since the conventional display device requires a lot of man-hours in the manufacturing process and has a relatively high defect rate, there is a tendency to prefer a liquid crystal display (LED) that is easier to manufacture and has a lower defect rate than the LED method.
한편, 위와 같은 종래의 액정 디스플레이의 경우는 전부분을 동일한 색상으로 발광되는 LED칩으로 제작할 수 밖에 없는 제약으로 인하여 특정 부위나 과정을 강조하여 나타낼 수 없었다.On the other hand, in the case of the conventional liquid crystal display as described above, due to the constraint that the entire part can be made of the LED chip emitting the same color, it could not be emphasized to indicate a specific part or process.
따라서, 특정부위를 강조하고자 할 때에는 그 특정 부위에 위치한 백라이트의 발광 다이오드를 반복적으로 점멸시켜 강조하였으므로, 그 원래의 목적에 비해 효과가 저조하였다.Therefore, in order to emphasize a specific portion, the light emitting diode of the backlight located in the specific portion is repeatedly flickered and emphasized, so that the effect is lower than the original purpose.
본 고안은 위와 같은 종래의 문제점을 해결하기 위한 것으로, 그 목적은 강조하기 위한 특정부위의 문자 및 형상을 시각변화를 통하여 표출시킬 수 있는 액정디스플레이의 백라이트 구조를 제공함에 있다.The present invention is to solve the above conventional problems, the object is to provide a backlight structure of the liquid crystal display capable of expressing the character and shape of the specific portion for highlighting through visual change.
이러한 본 고안의 목적은 액정 판넬의 이면에 부착되는 백라이트부에 서로 상이한 색상을 갖는 발광 다이오드를 적어도 2종류 이상 설치하여, 각 발광 다이오드를 동시에 혹은 제한적으로 점등시킴으로서 달성된다.This object of the present invention is achieved by providing at least two types of light emitting diodes having different colors to the backlight unit attached to the rear surface of the liquid crystal panel, thereby lighting each light emitting diode simultaneously or with limited lighting.
이하 본 고안의 액정 디스플레이의 백라이트 구조를 첨부도면을 참조하여 상세히 설명한다.Hereinafter, the backlight structure of the liquid crystal display of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 실시예의 액정 디스플레이를 나타낸 사시도로서, 살균가습기에 적용된 액정 디스플레이에 기기의 동작 과정의 일예를 표출시킨 것이다.FIG. 1 is a perspective view showing a liquid crystal display according to an embodiment of the present invention, and shows an example of an operation process of a device in a liquid crystal display applied to a sterilizing humidifier.
액정판넬(10)에는 각종의 문자와 기호등의 자판(11)이 배열되어 있으며, 상기 액정판넬(10)의 이면에는 발광기능을 제공하는 백라이트판(20)이 부착되어 있다.The liquid crystal panel 10 is arranged with a keyboard 11 such as various characters and symbols, and the back panel of the liquid crystal panel 10 is provided with a backlight plate 20 that provides a light emitting function.
또한, 백라이트판(20)과 액정판넬(10)사이에는 발광되는 빛을 확산시키는 확산지(30)가 개재되어 있다.In addition, a diffusion paper 30 is disposed between the backlight plate 20 and the liquid crystal panel 10 to diffuse the emitted light.
상기 백라이트판(20)은 제1도 (나)에서와 같이 일정배열로 전부분에 형성된 제1LED(21)와, 이 제2LED의 일부분(21')에 인접하여 형성된 제2LED(22)로 구성되어 있다.The backlight plate 20 is composed of a first LED 21 formed in all parts in a predetermined arrangement as shown in FIG. 1B and a second LED 22 formed adjacent to a portion 21 'of the second LED. It is.
위의 제1LED(21)와 제2LED(22)는 서로 다른 발광색을 가지며, 이 두 LED가 인접된 부위의 외곽은 제1LED(21)에 대해 차광막(23)으로 차단되어 발광시 빛을 집중시키고 산광을 방지하는 작용을 한다.The first LED 21 and the second LED 22 have different emission colors, and the outside of the area where the two LEDs are adjacent is blocked by the light shielding film 23 with respect to the first LED 21 to concentrate light when emitting light. It acts to prevent light scattering.
제2도는 본 고안의 실시예의 제어부를 나타낸 회로도로서, 입력단(40)에 형성된 다수의 단자(P1, P2, P3)가 각각 저항( R1, R2, R3)과 트랜지스터(TR1, TR2, TR3)를 통하여 백라이트판(20)의 전부분에 형성된 제1LED(21)와 차광막(23)에 의해 차단된 일부분(21')의 제1LED(21) 및 제2LED(22)에 로우(Low) 또는 하이(High) 신호를 보내는 구성이다.2 is a circuit diagram illustrating a control unit according to an embodiment of the present invention, in which a plurality of terminals P 1 , P 2 , and P 3 formed in the input terminal 40 have a resistor R 1 , R 2 , R 3 , and a transistor TR, respectively. The first LED 21 and the second LED 22 of the portion 21 ′ blocked by the first LED 21 and the light shielding film 23 formed on the entire portion of the backlight plate 20 through 1 , TR 2 , and TR 3 . ) To send a low or high signal.
상기 P1에 연결된 전체의 제1LED(21)와, P2에 연결된 일부분(21')의 제1LED 및 P3에연결된 제2LED(22)는 기기의 동작상태에 따라 상호간에 제한적으로 발광된다.The entire first LED 21 connected to P 1 , the first LED of the portion 21 ′ connected to P 2 , and the second LED 22 connected to P 3 emit a limited amount of light depending on the operating state of the device.
예를 들어, 본 고안이 적용되는 살균 가습기가 살균 동작중일 때에는 입력단(40)의 P1과 P3가 하이신호를 보내어 전부분의 제1LED(21)와 차광막(23)에 의해 구분된제2LED(22)가 온되어 발광하는 반면, P2는 로우신로를 보내어 상기 차광막(23)내에 위치한 일부분(21')의 제1LED는 오프상태가 된다.For example, when the sterilizing humidifier to which the present invention is applied is in sterilization operation, P 1 and P 3 of the input terminal 40 send a high signal to separate the second LEDs separated by the first LEDs 21 and the light shielding films 23. While 22 is turned on to emit light, P 2 sends a low path so that the first LED of the portion 21 'located in the light shielding film 23 is turned off.
또한, 살균동작이 중지되고 가습만 할 경우에는 P1과 P2가 하이로 되고 P3는 로우가 되어 전부분의 제1LED(21)와 차광막(23) 내부의 일부분(21')의 제1LED만이 발광하는 반면, 제2LED(22)는 오프상태가 된다.In addition, when the sterilization operation is stopped and only the humidification is performed, P 1 and P 2 go high and P 3 goes low, so that the first LEDs of all the first LEDs 21 and the part 21 'of the light shielding film 23 are inside. Only the light emits, while the second LED 22 is turned off.
한편, 위에서는 제1LED(21)(21')와 제2LED(22)로 구분하여 상호 제한적으로 서로 다른 색상의 빛을 발광토록 한 것이나, 상기 두 LED외에 또다른 LED를 추가적으로 배열하는 것도 가능하거니와 다수 종류의 LED를 제한적으로 발광시켜 액정판넬(10)의 특정 위치상의 자판(11)을 강조하는 것은 모두 본 고안의 범주에 속한다.On the other hand, the first LED (21) (21 ') and the second LED 22 is divided into two to emit light of different colors in a mutually limited, it is also possible to additionally arrange another LED in addition to the two LEDs and It is all within the scope of the present invention to emphasize the keyboard 11 on a specific position of the liquid crystal panel 10 by restricting light emission of a plurality of types of LEDs.
따라서, 위와 같은 본 고안은 백라이트판(20)에 형성된 제1LED(21)를 녹색으로하고 제2LED를 적색으로 하여 살균 가습기에 적용할 경우, 살균을 하는 동안에는 액정판넬(10)에 "살균증"이란 문자표시와 벌레 형상의 특정 부위만이 강조색인 적색을 띠게 되고, 나머지 일반 부위는 전부 녹색을 띠게 된다.Therefore, the present invention as described above is applied to the sterilizing humidifier with the first LED 21 formed in the backlight plate 20 in the green and the second LED in the red, "sterilization" to the liquid crystal panel 10 during sterilization Only certain parts of the letter mark and insect shape become red, and the rest of the general areas are green.
위와 달리 단순한 가습작동중 일 때에는 "살균증"이란 문자표시와 벌레 형상의 특정 부위만이 강조되었던 강조색인 적색이 없어지고 제1LED(21)(21')의 모든 부위가 점등되어 녹색을 띠게 된다.Unlike the above, during the simple humidification operation, “sterilization” disappears as a highlight color where only a specific portion of the letter display and insect shape is emphasized, and all parts of the first LEDs 21 and 21 'are turned on to have a green color. .
즉, 차광막(23)이 특정 부위에 설치되어 강조색을 갖는 제2LED(22)를 발광시킴에 따라 주위의 색상과 구분 강조되어 지고, 또한 특정부위가 지속적으로 깜빡거리게 된다.That is, as the light shielding film 23 is installed at a specific site to emit the second LED 22 having an accent color, the light shielding film 23 is distinguished from the surrounding color, and the specific site is continuously flickered.
이와 같은 본 고안은 색상의 사이함과 동적인 시각변화로서 기기의 동작상태를 표출시킴에 따라, 보다 용이하게 기기의 동작 상태를 식별할 수 있는 효과가 있다.As such, the present invention expresses the operating state of the device as the difference in color and the dynamic visual change, thereby making it possible to more easily identify the operating state of the device.
