Description

플라즈마 디스플레이 패널Plasma display panel

본 발명은 플라즈마 디스플레이 패널(Plasma Display Panel)에 관한 것으로서, 특히 방전효율 및 콘트라스트를 향상시키기 위하여 내부구조를 변형시킨 PDP구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plasma display panel, and more particularly, to a PDP structure in which an internal structure is modified to improve discharge efficiency and contrast.

도 1 은 일반적인 3전극 면방전 PDP의 구조를 나타낸 것으로 구조를 살펴보면, 화상의 표시면인 전면기판(1)과, 상기 전면기판(1)과 일정거리를 사이에 두고 평행하게 위치한 배면기판(2)으로 이루어지는데, 상기 전면기판(1)에는 배면기판(2) 대향면에 일정간격으로 형성된 복수개의 유지전극라인(6,7)과, 상기 복수개의 유지전극라인(6,7)위에 형성되어 방전전류를 제한하는 유전층(8)과, 상기 유전층(8)위에 형성되어 상기 유지전극라인(6,7)을 보호하는 보호층(9)으로 구성되며, 상기 배면기판(2)에는 복수개의 방전공간을 형성시키는 복수개의 격벽(3)과, 상기 격벽(3)사이에 유지전극라인(6,7)과 직교하도록 형성된 복수개의 어드레스 전극라인(4)과, 상기 각 방전공간의 내부면 중 양측 격벽면과 배면 기판면에 해당 어드레스전극라인(4)을 감싸도록 형성되어 방전시 가시광선을 방출하는 형광층(5)으로 이루어진다.1 illustrates a structure of a general three-electrode surface discharge PDP. Referring to the structure, the front substrate 1, which is a display surface of an image, and the rear substrate 2 disposed in parallel with a predetermined distance therebetween The front substrate (1) is formed on the plurality of sustain electrode lines (6,7) and the plurality of sustain electrode lines (6,7) formed at regular intervals on the opposite surface of the back substrate (2) A dielectric layer 8 for limiting discharge current and a protective layer 9 formed on the dielectric layer 8 to protect the sustain electrode lines 6 and 7, and a plurality of discharges on the back substrate 2. A plurality of partitions 3 forming a space, a plurality of address electrode lines 4 formed to be orthogonal to the sustain electrode lines 6 and 7 between the partitions 3, and both sides of an inner surface of each of the discharge spaces. It is formed to surround the address electrode line 4 on the partition surface and the back substrate surface. When it made of the phosphor layer (5) for emitting visible light.

그리고 상기에서 한쌍의 유지전극라인은 도 2 에 나타낸 바와같이 약 300μm의 폭을 갖으며 투명전극라인(6)과 버스전극라인(7)으로 구성되는데, 상기 투명전극라인(6)은 양단에 방전전압이 공급되면 해당 방전공간 내부에서 상호 면방전을 일으키고, 상기 버스전극라인(7)은 금속재질로서 약50∼100μm의 폭을 갖으며 투명전극라인(6)위에 각각 형성되어 투명전극라인의 저항에 의한 전압강하를 방지한다.As shown in FIG. 2, the pair of sustain electrode lines have a width of about 300 μm and are composed of a transparent electrode line 6 and a bus electrode line 7, the transparent electrode lines 6 having both ends. When the discharge voltage is supplied to the surface, mutual surface discharge occurs in the corresponding discharge space, and the bus electrode line 7 is a metal material having a width of about 50 to 100 μm and formed on the transparent electrode line 6 to be transparent. Prevent voltage drop caused by resistance of electrode line.

도 2 는 도 1 의 상,하부 기판이 결합된후의 플라즈마 표시장치 단면도를 나타낸 것으로서 이해를 돕기위해 상부구조를 90도 회전하여 도시하였다.FIG. 2 is a cross-sectional view of the plasma display device after the upper and lower substrates of FIG. 1 are combined, and the upper structure is rotated 90 degrees for better understanding.

상기와 같이 구성된 종래기술에 의한 PDP중 임의의 셀의 화상표시과정은 다음과 같다.The image display process of any cell in the PDP according to the prior art configured as described above is as follows.

먼저, 해당 투명전극라인(6)에 150V∼300V의 방전개시전압이 공급되면 상기 투명전극라인(6) 간에 면방전(보조방전)이 일어나 해당 방전공간의 내부면에 벽전하가 형성된다.First, when a discharge start voltage of 150 V to 300 V is supplied to the transparent electrode line 6, surface discharge (auxiliary discharge) occurs between the transparent electrode lines 6 to form wall charges on the inner surface of the corresponding discharge space.

그후, 투명전극라인(6)과 해당 어드레스 전극라인(4)에 어드레스 방전전압이 공급되면 상기 투명전극라인(6)과 해당 어드레스 전극라인(4)간의 어드레스 방전(주방전)이 일어나게 된다. 즉, 셀 내부에서 전계가 발생하여 방전가스중의 미량전자들이 가속되고, 가속된 전자와 가스중의 중성입자가 충돌하여 전자와 이온으로 전리되며, 상기 전리된 전자와 중성입자와의 또 다른 충돌등으로 중성입자가 점차 빠른 속도로 전자와 이온으로 전리되어 방전가스가 플라즈마 상태로 되는 동시에 진공 자외선이 발생된다. 상기 발생된 자외선이 형광층(5)을 여기시켜 가시광선을 발생시키고 발생된 가시광선은 전면기판(1)을 통해서 외부로 출사되면 외부에서 임의의 셀의 발광 즉, 화상표시를 인식할 수 있게된다.Thereafter, when an address discharge voltage is supplied to the transparent electrode line 6 and the address electrode line 4, an address discharge (main discharge) occurs between the transparent electrode line 6 and the address electrode line 4. In other words, an electric field is generated inside the cell, and the trace electrons in the discharge gas are accelerated, the accelerated electrons and the neutral particles in the gas collide with each other, and are ionized into electrons and ions, and another collision between the ionized electrons and the neutral particles is performed. Neutral particles are gradually ionized into electrons and ions at high speed, and the discharge gas is turned into a plasma state and vacuum ultraviolet rays are generated. The generated ultraviolet rays excite the fluorescent layer 5 to generate visible light, and when the generated visible light is emitted to the outside through the front substrate 1, light emitted from any cell can be recognized from the outside, that is, image display. do.

그후, 해당 투명전극라인(6)에 150V 이상의 유지방전전압이 공급되면 상기 투명전극라인(6)간에 유지방전이 일어나 임의의 셀의 발광이 일정 시간동안 유지된다.After that, when the sustain discharge voltage of 150 V or more is supplied to the transparent electrode line 6, the sustain discharge occurs between the transparent electrode lines 6, so that light emission of any cell is maintained for a predetermined time.

그러나 상기와 같은 종래 구조는 주방전부(유지전극)가 전면기판에 있으므로 격벽높이의 증가에도 불구하고 구조변경이 어렵고 또한 방전효율의 증가를 위하여 입체형 구조의 도입도 투과율의 저하에 의하여 쉽게 적용하기 어렵다. 또한 가시광선의 투과를 위해 유지전극을 반드시 투명전극으로 형성하여야 하는데, 투명전극에 전압을 인가하기 위하여 사용되는 버스전극은 약 10∼25%의 광손실을 초래하게 되고, 외부광의 반사에 의한 콘트라스트 특성이 저하되고 있다.However, the conventional structure as described above is difficult to change the structure despite the increase in the height of the partition, and the introduction of the three-dimensional structure to increase the discharge efficiency, it is difficult to apply easily due to the decrease in transmittance. . In addition, the sustain electrode must be formed as a transparent electrode to transmit visible light. A bus electrode used to apply a voltage to the transparent electrode causes an optical loss of about 10 to 25%, and contrast characteristics due to reflection of external light. This is falling.

또한, 발광부위가 완전히 외부에 노출되어 있기 때문에 외부광에 의한 반사율이 높아서 외부광에 대한 콘트라스트 특성이 나쁘며, 이의 향상을 위하여 30∼50%에 이르는 광손실에도 불구하고 필터(filter:미도시)를 적용해야 하는 문제점이 있었다.In addition, since the light emitting part is completely exposed to the outside, the reflectance caused by the external light is high, resulting in poor contrast characteristics to the external light, and a filter (not shown) despite the light loss of 30 to 50% for improvement thereof. There was a problem to apply.

본 발명은 상기한 바와같은 종래 기술의 문제점을 해결하기 위하여 발명된 것으로 어드레스전극과 격벽 그리고 형광층을 전면기판측에 형성하고, 배면기판측에는 유지전극이 가시광의 반사경 역활을 하도록 구성시킴으로서, 형광층이 컬러필터의 역할과 가시광 발생원의 역할을 하도록 하고 전면기판의 개구율을 최대로 하여 방전효율 및 콘트라스트를 극대화시킨 플라즈마 디스플레이 패널을 제공하는데 목적이 있다.The present invention has been invented to solve the problems of the prior art as described above, by forming an address electrode, a partition, and a fluorescent layer on the front substrate side, and a sustain electrode on the rear substrate side to serve as a reflector of visible light. It is an object of the present invention to provide a plasma display panel that plays a role of the color filter and a source of visible light and maximizes the aperture ratio of the front substrate to maximize discharge efficiency and contrast.

이하, 본 발명을 첨부도면을 참조하여 설명하면 다음과 같다.Hereinafter, the present invention will be described with reference to the accompanying drawings.

먼저 본 발명 PDP의 구조는 도 3 에 도시된 바와같이(상부기판을 90도 회전하여 도시함) 화상의 표시면인 전면기판(101)과, 상기 전면기판(101)과 일정거리를 사이에 두고 평행하게 위치한 배면기판(102)으로 이루어지고, 상기 전면기판(101)에는 복수개의 방전공간을 형성시키는 복수개의 격벽(103)과, 상기 격벽(103)의 양측면과 전면 기판면에 형성되는 형광층(105)과, 상기 격벽(103)의 상단부를 따라 평행을 이루는 어드레스전극(104)이 광차단층(110;BM층)상에 형성되며, 상기 배면 기판(102)에는 2개가 한쌍을 이루는 금속재질의 유지전극라인(106)과, 상기 유지전극라인(106)위에 형성되어 방전전류를 제한하는 유전층(108)과, 상기 유전층(108)위에 형성되어 상기 유지전극라인(106)을 보호하는 보호층(109)으로 구성된다.First, the structure of the PDP of the present invention is as shown in FIG. The front substrate 101 includes a plurality of partitions 103 for forming a plurality of discharge spaces, and a fluorescent layer formed on both side surfaces of the partitions 103 and the front substrate surface. 105 and an address electrode 104 parallel to the upper end of the barrier 103 are formed on the light blocking layer 110 (BM layer), and the back substrate 102 has a pair of metal materials. A dielectric layer 108 formed on the sustain electrode line 106, a dielectric layer 108 formed on the sustain electrode line 106 to limit discharge current, and a protective layer formed on the dielectric layer 108 to protect the sustain electrode line 106. 109.

특히, 상기 구조에 있어서 형광체는 가시광의 투과가 용이하도록 최대한 얇게 도포하며, 유지전극라인(106)은 도 4 와 같이 가시광의 반사경 역할을 하도록 전극의 폭을 넓게 형성시킨다.In particular, in the above structure, the phosphor is applied as thinly as possible to facilitate the transmission of visible light, and the sustain electrode line 106 forms a wide width of the electrode to serve as a reflector of visible light as shown in FIG. 4.

이와같이 구성되는 본 발명 PDP의 동작을 살펴보면 다음과 같다.Looking at the operation of the present invention PDP configured as described above is as follows.

먼저, 해당 유지전극라인(106)에 방전개시전압이 공급되면 상기 쌍을 이루는 유지전극라인(106) 간에 면방전(보조방전)이 일어나 해당 방전공간의 내부면에 벽전하가 형성된다.First, when the discharge start voltage is supplied to the sustain electrode line 106, surface discharge (auxiliary discharge) occurs between the pair of sustain electrode lines 106, and wall charges are formed on the inner surface of the discharge space.

그후, 유지전극라인(106)과 해당 어드레스 전극라인(104)에 어드레스 방전전압이 공급되면 상기 유지전극라인(106)과 해당 어드레스 전극라인(104)간의 어드레스 방전(주방전)이 일어나게 되면 방전가스가 플라즈마 상태로 되는 동시에 진공 자외선이 발생된다. 상기 발생된 자외선이 형광층(105)을 여기시켜 가시광선을 발생시키고 발생된 가시광선은 형광층(105)을 투과하여 전면기판(101)을 통해서 외부로 출사되면 외부에서 임의의 셀의 발광 즉, 화상표시를 인식할 수 있게되는 것이다.Thereafter, when an address discharge voltage is supplied to the sustain electrode line 106 and the address electrode line 104, the discharge gas is generated when an address discharge (main discharge) occurs between the sustain electrode line 106 and the address electrode line 104. Becomes the plasma state and vacuum ultraviolet rays are generated. When the generated ultraviolet rays excite the fluorescent layer 105 to generate visible light, and the generated visible light is transmitted through the fluorescent layer 105 and emitted to the outside through the front substrate 101, light of an arbitrary cell is externally emitted. The image display can be recognized.

이때, 형광층(105)으로 부터 내부로 방출된 가시광은 배면기판(102)상의 금속재질로 형성된 유지전극(106)에 의해 다시 전면으로 반사되어 외부로 방출되게 된다.At this time, visible light emitted from the fluorescent layer 105 to the inside is reflected back to the front by the sustain electrode 106 formed of a metal material on the back substrate 102 is emitted to the outside.

그후, 해당 유지전극라인(106)에 유지방전전압이 공급되면 라인간에 유지방전이 일어나 임의의 셀의 발광이 일정시간동안 유지되게 된다.Thereafter, when the sustain discharge voltage is supplied to the sustain electrode line 106, sustain discharge occurs between the lines so that light emission of any cell is maintained for a predetermined time.

특히, 본 발명의 구조는 어드레스전극(104)을 격벽(103)과 최대한 가깝게 위치시켜 개구율의 감소를 최소화 하게 되고, 어드레스전극(104)에 의한 콘트라스트 저하를 방지하도록 광차단층(110)이 격벽(103)을 따라 형성되었다.Particularly, in the structure of the present invention, the address electrode 104 is positioned as close as possible to the partition 103 to minimize the reduction of the aperture ratio, and the light blocking layer 110 is formed to prevent the degradation of the contrast by the address electrode 104. 103).

또한 배면기판(102)상에는 반사층역활을 하도록 유지전극(106)을 형성하여 휘도를 증가시키게 되는데 상기 반사층역활을 위한 본 발명의 다른실시예를 이하에서 살펴본다.In addition, the sustain electrode 106 is formed on the rear substrate 102 to increase the brightness of the reflective layer, and another embodiment of the present invention for the reflective layer will be described below.

도 5 는 본 발명의 다른 실시예로서 유지전극(106)의 전극폭은 종래와 동일한 상태에서 전극 양측에 가시광 반사를 위한 반사보조체(116)를 형성한 예를 나타낸다.FIG. 5 shows an example in which the reflective assistant 116 for reflecting visible light is formed on both sides of the electrode in the same state as that of the sustain electrode 106 as another embodiment of the present invention.

그리고 도 6 는 본 발명의 또다른 실시예로서 유지전극 하부의 배면기판(102)전면에 유지전극과 전기적으로 절연된 반사층(126)을 형성하여 형광층(105)으로 부터 방출된 가시광을 반사시키게 된다.6 illustrates a reflective layer 126 electrically insulated from the sustain electrode on the back substrate 102 under the sustain electrode to reflect visible light emitted from the fluorescent layer 105 as another embodiment of the present invention. do.

이상 설명한 바와같이 본 발명의 플라즈마 표시장치는 투과형 형광체구조를 형성하여 형광층이 컬러필터의 역할과 가시광 발생원의 역할을 겸하도록 함으로 실제 방출되는 광효율을 향상시키게 되고, 가시광선에 대한 반사율 및 개구율이 증가하게 되어 휘도가 상승하게 되는 효과가 있다. 광학적으로는 유지전극이 가시광을 90%이상 반사시킬 수 있는 반사경역활을 하므로, 발생된 가시광의 방출효율을 최대한 증가시킬 수 있다.As described above, the plasma display device of the present invention forms a transmissive phosphor structure so that the fluorescent layer serves as a color filter and a visible light source, thereby improving light efficiency, and reflectance and aperture ratio of visible light are improved. There is an effect that the brightness is increased to increase. Optically, since the sustain electrode plays a reflection role capable of reflecting visible light by 90% or more, the emission efficiency of the generated visible light can be maximized.

또한, 유지방전전극의 전극폭을 증가시킴으로 전극의 두께를 얇게 가져갈 수 있게되어 제작수율이 향상되고, 증가된 전극폭에 의하여 선저항값이 충분히 적어질 수 있으므로 큰 선저항값에 의한 방전불균형을 감소시키는 효과를 가져올 수 있게된다.In addition, by increasing the electrode width of the sustain discharge electrode, the thickness of the electrode can be thinned, so that the production yield can be improved, and the wire resistance value can be sufficiently reduced by the increased electrode width. It can bring about a reducing effect.
