본 발명은 패널 구동을 위한 듀얼 스캔 방식의 스캔라인 배선 방법에 관한 것으로, 보다 상세하게는 PM(Passive Matrix)방식의 OLED를 구동하기 위해 현재 적용되고 있는 듀얼(Dual) 스캔(Scan) 방식에서 듀얼 스캔라인의 배선을 각 개별의 두개의 셀 형식으로 배선하여 각 구역을 별도의 셀처럼 한 개의 IC를 사용하여 구동함으로써 스캔라인의 저항을 감소시키고 소비전력을 감소시킬 수 있게 한 패널 구동을 위한 듀얼 스캔 방식의 스캔라인 배선 방법에 관한 것이다.The present invention relates to a dual scan type scan line wiring method for driving a panel. More specifically, the present invention relates to a dual scan type in a dual scan method that is currently being applied to drive a PM (Passive Matrix) OLED. Dual for driving the panel, which allows wiring of the scanline in two separate cell types to drive each zone using a single IC as a separate cell, reducing the resistance of the scanline and reducing power consumption. The present invention relates to a scan line wiring method of a scan method.
일반적으로 현재 PM 방식의 OLED 패널 구동시 고해상도로 갈수록 많은 패널 사이즈 증가와 함께 스캔라인의 저항 증가와 이로 인한 전압강하 등으로 인해 소비전력 상승을 초래하고 있다.In general, in the case of driving PM-type OLED panels, power consumption is increasing due to the increase in panel size and the increase in the resistance of the scan line and the resulting voltage drop.
이를 방지하기 위하여 현재는 패널을 데이터라인과 스캔라인으로 나누어 몇 개의 IC를 사용하여 패널을 두 구역으로 분리하여 구동하는 듀얼 스캔 방식을 적용하고 있다.To prevent this, currently, the panel is divided into a data line and a scan line, and a dual scan method using a plurality of ICs to separate the panel into two zones is used.
도 1 은 종래의 패널 구동을 위한 듀얼 스캔 방식의 스캔라인 배선을 도시한 도면이다.1 is a diagram illustrating a scan line wiring of a dual scan method for driving a conventional panel.
도 1 에 도시한 바와 같이, 종래에는 패널 사이즈 증가로 인한 스캔라인의 저항증가를 1/2로 감소시키기 위한 방법으로 듀얼 스캔 구동 방식이 사용되는데, 이 방식은 패널의 상단에서 하단까지 연장되는 데이터라인이 패널 중앙부에서 분리되어 있다. 그리고 한 프레임(frame)의 데이터를 반으로 나누어 두 개의 메모리에 각각 저장한 다음 각 메모리에 저장된 데이터를 패널의 상단에서 패널의 중앙까지 와 패널의 하단에서 패널의 중앙까지 공급하고, 스캔라인을 동시 또는 약간의 시간차를 두고 스캐닝하기 때문에, 앞에서 설명한 바와 같이 데이터라인의 부하를 1/2로 감소시킬 수 있을 뿐만 아니라 스캐닝 신호가 스캔라인에 충분한 시간 동안 인가되도록 할 수 있다.As shown in FIG. 1, a dual scan driving method is conventionally used as a method for reducing the increase in the resistance of a scan line by 1/2 due to an increase in panel size, which is a data extending from the top to the bottom of the panel. The line is separated at the center of the panel. The data of one frame is divided in half and stored in two memories, and the data stored in each memory is supplied from the top of the panel to the center of the panel and from the bottom of the panel to the center of the panel. Alternatively, because scanning with a slight time difference, as described above, not only can the load on the data line be reduced to 1/2 but also the scanning signal can be applied to the scan line for a sufficient time.
그러나, 이러한 듀얼 스캔 방식으로 구동되는 패널에서는 한 프레임의 스캔라인마다 각각 패널의 상, 하에 구비된 별도의 IC와 연결시켜 배선하므로 IC 개수의 증가와 IC 본딩(Bonding) 등의 공정이 추가되어 모듈의 가격이 상승하고 작업공정도 복잡하게 되는 문제점이 있다. 또한, 스캔라인의 사이드 부위의 저항과 중앙부위의 저항의 차이로 인해 휘도의 불균일과 전압강하 발생으로 인하여 소비전력이 증가하는 문제점이 있다.However, the panel driven by the dual scan method is connected to separate ICs provided at the top and the bottom of the panel for each scan line of the frame so that the number of ICs and the IC bonding process are added to the module. There is a problem that the price of the rise and the work process is complicated. In addition, there is a problem in that power consumption increases due to uneven brightness and voltage drop due to the difference between the resistance of the side portion of the scan line and the resistance of the center portion.
본 발명은 상기와 같은 종래 기술의 문제점을 해결하기 위해 창안된 것으로, PM방식의 OLED를 구동하기 위해 현재 적용되고 있는 듀얼 스캔 방식에서 듀얼 스캔라인의 배선을 각 개별의 두개의 셀 형식으로 배선하여 각 구역을 별도의 셀처럼 한 개의 IC를 사용하여 구동함으로써 스캔라인의 저항을 감소시키고 소비전력을 감소시킬 수 있게 한 패널 구동을 위한 듀얼 스캔 방식의 스캔라인 배선 방법을 제공하는데 그 목적이 있다.
The present invention was devised to solve the above problems of the prior art, and in the dual scan method currently applied to drive the OLED of the PM method, the wiring of the dual scan line is formed in each of two individual cell types. The purpose of the present invention is to provide a dual scan type scanline wiring method for driving a panel that enables each zone to be driven using a single IC as a separate cell, thereby reducing scanline resistance and power consumption.
상기와 같은 목적을 달성하기 위한 본 발명은 패널의 수평 방향으로 형성된 다수의 스캔라인과, 상기 스캔라인과 수직으로 교차하는 수직 방향으로 패널 상반부에 형성되는 다수의 데이터라인을 포함하는 제 1 데이터라인 그룹과, 상기 데이터라인과 각각 동일선상으로 패널 하반부에 형성되는 다수의 데이터라인을 포함하는 제 2 데이터라인 그룹과, 상기 두 데이터라인 그룹은 패널 중앙에서 서로 분리되어 있는 듀얼 스캔 방식의 스캔라인 배선 방법에 있어서, 상기 제 1 데이터라인 그룹과 수직으로 교차하는 다수의 스캔라인을 제 1 데이터라인으로 데이터를 제공하는 IC와 배선하고, 상기 제 2 데이터라인 그룹과 수직으로 교차하는 다수의 스캔라인을 제 2 데이터라인으로 데이터를 제공하는 IC와 배선하여 구성한 것을 특징으로 한다.The present invention for achieving the above object is a first data line comprising a plurality of scan lines formed in the horizontal direction of the panel, and a plurality of data lines formed in the upper half of the panel in the vertical direction perpendicular to the scan line A second data line group including a group, a plurality of data lines formed at the lower half of the panel in the same line as the data line, and the two data line groups are separated from each other at the center of the panel by a dual scan type scan line wiring A method, comprising: interconnecting a plurality of scan lines perpendicular to the first group of data lines with an IC providing data to a first data line, and a plurality of scan lines perpendicular to the group of second data lines. And an IC that provides data to the second data line.
본 발명에서, 상기 듀얼 스캔라인을 서로 교호하여 좌우로 어긋나게 연결시켜 배선함을 특징으로 한다.In the present invention, the dual scan lines are alternately connected to each other alternately from side to side and are wired.

위와 같이, 본 발명은 PM방식의 OLED를 구동하기 위해 현재 적용되고 있는 듀얼 스캔 방식에서 듀얼 스캔라인의 배선을 각 개별의 두개의 셀 형식으로 배선하여 각 구역을 별도의 셀처럼 한 개의 IC를 사용하여 구동함으로써 스캔라인의 저항을 감소시키고 소비전력을 감소시킬 수 있게 한다.As described above, the present invention uses a single IC as a separate cell by wiring the wiring of the dual scan line in two separate cell types in the dual scan method currently applied to drive the PM type OLED. In this case, the resistance of the scan line and the power consumption can be reduced.
이하, 본 발명의 바람직한 실시예를 첨부한 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail.
도 2 는 본 발명에 의한 패널 구동을 위한 듀얼 스캔 방식의 스캔라인 배선 방법을 설명하기 위한 도면이고, 도 3 은 본 발명의 다른 실시예에 따른 패널 구동을 위한 듀얼 스캔 방식의 스캔라인 배선 방법을 설명하기 위한 도면이다.2 is a view illustrating a dual scan type scan line wiring method for driving a panel according to the present invention, and FIG. 3 is a dual scan type scan line wiring method for driving a panel according to another embodiment of the present invention. It is a figure for demonstrating.
도 2 에 도시한 바와 같이, 본 발명은 패널의 수평 방향으로 형성된 다수의 스캔라인(14)과, 상기 스캔라인(14)과 수직으로 교차하는 수직 방향으로 패널 상반부(10)에 형성되는 다수의 데이터라인(12)을 포함하는 제 1 데이터라인 그룹과, 상기 데이터라인(12)과 각각 동일선상으로 패널 하반부(10')에 형성되는 다수의 데이터라인(12')을 포함하는 제 2 데이터라인 그룹과, 상기 두 데이터라인 그룹은 패널 중앙에서 서로 분리되어 있다.As shown in FIG. 2, the present invention provides a plurality of
그리고, 이러한 듀얼 스캔 방식의 스캔라인을 배선함에 있어서, 본 발명은 상기 제 1 데이터라인 그룹과 수직으로 교차하는 다수의 스캔라인(14)을 제 1 데이터라인으로 데이터를 제공하는 IC(20)와 배선하고, 상기 제 2 데이터라인 그룹과 수직으로 교차하는 다수의 스캔라인(14')을 제 2 데이터라인으로 데이터를 제공하는 IC(20)와 배선한다.In the wiring of the dual scan type scan line, the present invention provides a plurality of
특히, 상기 듀얼 스캔라인을 서로 교호하여 좌우로 어긋나게 연결시켜 배선한다. 즉, 기존의 하나의 PAD 방식을 듀얼 스캔에 적용하여 두개의 PAD, 두개의 IC를 통한 듀얼 스캔 방식을 구현하는 것이다.In particular, the dual scan lines are alternately connected to each other and wired alternately from side to side. That is, by applying one existing PAD method to dual scan, a dual scan method through two PADs and two ICs is implemented.
그러면 두개의 IC를 이용하여 각기 패널을 별도로 구동하므로 하나의 화면 또는 별개의 화면을 동시에 상,하 패널에서 구동하여 화면에 표시할 수 있다. 그리고, 도 1과 도 2 에 도시한 두개의 패널을 구분하는 절단선은 실제로 눈에 보이지 않을 정도로 작은폭으로 두 화면이 단절되어 형성된다.Then, each panel is driven separately using two ICs, so one screen or separate screens can be driven simultaneously on the upper and lower panels and displayed on the screen. In addition, the cutting line for dividing the two panels shown in FIGS. 1 and 2 is formed by cutting the two screens in such a small extent that they are not actually visible.
그리고, 본 발명은 도 2 에 도시한 바와 같이 듀얼 스캔라인을 전류의 흐름이 양분되어 저항이 반으로 감소되도록 스캔라인의 양단을 모두 IC와 연결시켜 배선할 수도 있다.As shown in FIG. 2, the dual scan line may be wired by connecting both ends of the scan line to the IC so that the current flow is divided into two and the resistance is reduced by half.
즉 듀얼 스캔방식에서 스캔라인의 배선을 양단으로 모두 배선하고 데이터라인에 데이터를 제공하는 IC 연결함으로써 스캔라인에서 발생하는 저항과 전압강하로 인한 중앙부위와 양사이드 부위의 휘도차를 줄이고 소비전력을 감소시키는 것이다.In other words, in the dual scan method, the wiring of the scan line is wired at both ends and the IC is connected to provide data to the data line, thereby reducing the luminance difference between the center and both sides due to the resistance and voltage drop generated in the scan line and reducing power consumption. To reduce.
또한, 상기 스캔라인의 모든 배선은 최단거리 배선을 위해 일정각도를 가진 사선과 직선으로 구성하여 배선한다. In addition, all the wirings of the scan line are wired by forming a diagonal line and a straight line having a predetermined angle for the shortest distance wiring.
위와 같이 본 발명은 듀얼 스캔 방식에서 듀얼 스캔라인의 배선을 각 개별의 두개의 셀 형식으로 배선하고 각 구역을 별도의 셀처럼 한 개의 IC를 사용하여 구동하므로 스캔라인의 사이드 부위의 저항과 중앙부위의 저항의 차를 줄여 패널의 사이드 부위와 중앙부위 간에 휘도의 차를 줄일 수 있는 것이다.As described above, in the dual scan method, since the wiring of the dual scan line is wired in two separate cell types and each zone is driven using one IC as a separate cell, the resistance and the center of the side portion of the scan line are driven. By reducing the difference in resistance, the difference in luminance between the side and center of the panel can be reduced.
상술한 바와 같이, 본 발명은 PM방식의 OLED를 구동하기 위해 현재 적용되고 있는 듀얼 스캔 방식에서 듀얼 스캔라인의 배선을 각 개별의 두개의 셀 형식으로 배선하여 각 구역을 별도의 셀처럼 한 개의 IC를 사용하여 구동함으로써 스캔라인의 저항을 감소시키고 소비전력을 감소시킬 수 있는 이점이 있다.As described above, the present invention is to provide a single IC by wiring the wiring of the dual scan line to each individual two cell type in the dual scan method currently applied to drive the PM type OLED. By driving with the advantage of reducing the resistance of the scan line and the power consumption can be reduced.
또한, 본 발명은 데이터라인으로 데이터를 제공하는 IC 와 스캔라인을 배선하므로 IC 개수의 절감에 따른 모듈 비용을 절감시키고 IC 본딩 등의 공정이 줄어 작업공정을 단순화하는 이점이 있다.In addition, the present invention has the advantage of simplifying the work process by reducing the module cost and IC bonding process according to the reduction of the number of ICs by wiring the IC and the scan line for providing data to the data line.
또한, 본 발명은 스캔라인의 사이드 부위의 저항과 중앙부위의 저항의 차를 줄여 패널의 사이드 부위와 중앙부위 간에 휘도의 불균일을 해소하는 이점이 있다.
In addition, the present invention has the advantage of reducing the difference between the resistance of the side portion of the scan line and the resistance of the center portion to solve the unevenness of luminance between the side portion and the center portion of the panel.
