Abstract
The present invention discloses a plasma display panel which comprises a plurality of red, green and blue display units, wherein the display units are arranged on a base plate and are respectively formed into a plurality of red, green and blue display unit passages. The directions of the red, green and blue display unit passages face to an air ventilating hole on the base plate to rapidly exhaust air or ventilate the air.
Description
Technical field
The present invention relates to a kind of plasma display, and be particularly related to a kind of plasma display that can bleed rapidly or ventilate.
Background technology
Plasma display (Plasma Display Panel, PDP) have large scale, wide visual angle, high-resolution with it and show multinomial characteristics such as full-color image ability, make its display effect be much better than present cathode ray tube (Cathode Ray Tube, CRT) therefore display is subjected to popular attention in recent years gradually.
Please refer to Fig. 1, it illustrated is the stereogram of traditional plasma display.Plasma display is made of prebasal plate 102 and metacoxal plate 108.A plurality ofly keep electrode (sustainingelectrode) X and a plurality of scan electrode (scanning electrode) Y is set in parallel on the front glass substrate 102 alternately, and describedly can form and define a plurality of transparency electrode (not shown) earlier before keeping electrode X and scan electrode Y forming, this transparency electrode has different graphical definition according to different designs, then do not add book in this manual.Above-mentioned electrode X and the scan electrode Y of keeping is by 104 coverings of dielectric layer (dielectric layer).104 protective layers that are made of magnesium oxide 106 of dielectric layer cover, and keep electrode X, scan electrode Y and dielectric layer 104 in order to protection.In addition, a plurality of address electrodes (addressing electrode) A is arranged on the metacoxal plate 108 abreast, and is covered by dielectric layer 116.Wherein, the direction that is provided with of address electrode A intersects each other with the direction that is provided with of keeping electrode X and scan electrode Y.Spaced walls (rib) 112 is arranged on the metacoxal plate 108 abreast along the direction with address electrode A, and fluorescence coating 110 is coated between the two adjacent spaced walls 112.
Cavity between prebasal plate 102 and the metacoxal plate 108 is discharge space (discharge space), wherein has been full of the discharge gas (discharge gas) that is mixed by neon and xenon.Keep at one on the prebasal plate 102 that corresponding address electrode A defines a display unit on electrode X and scan electrode Y and the metacoxal plate 108.So, then a plurality of electrode X, scan electrode Y and address electrode A of keeping can define a plurality of display units of arranging with matrix (matrix) form on plasma display.By the gas that excites in the discharge space, the gas that is excited will be emitted ultraviolet light.Fluorescence coating 110 then behind the ultraviolet light that absorbs specific wavelength, is emitted visible light.
The configuration mode of a plurality of display units of plasma display can be horizontal or delta arrangement.Please refer to Fig. 2, it illustrated is the schematic diagram of the correlation of a plurality of display units of horizontal formula of plasma display and each electrode.Between adjacent spaced walls (rib), can obtain the display unit of different colours by the fluorescence coating that forms different colours.As shown in Figure 2, data electrode A1 is in order to control red display unit R 1 and R2, and data electrode A2 is in order to control green display unit G1 and G2, and data electrode A3 then is in order to control blue display unit B 1 and B2.When driving display unit, at first remove in the period (erase period), the video data of all display units is removed one.Afterwards, in an addressing period (address period), scan scan electrode Y1 and Y2 in regular turn, and choose the display unit that to light by addressing electrode A1～A3.Afterwards, keep in discharge period (sustain discharge period) in one, by providing an alternating voltage in adjacent electrode X1 and the scan electrode Y1 of keeping, and keep between electrode X2 and the scan electrode Y2, the display unit that is selected will be continued to light.
Please refer to Fig. 3, it illustrated is the schematic diagram of the correlation of a plurality of display units of traditional delta arrangement formula and each electrode.A plurality of display units of delta arrangement formula use spaced walls (rib) 302 to reach.Now be example with adjacent and interconnected green display unit G2 and red display unit R 2.Green display unit G2 is controlled by data electrode A2 and scan electrode Y1, and red display unit R 3 is controlled by data electrode A1 and scan electrode Y1.When scan electrode Y1 is scanned, can choose green display unit G2 and red display unit R 3 respectively respectively by scan electrode A1 and A2.
As previously described, the discharge space between prebasal plate 102 and the metacoxal plate 108 has been full of the discharge gas that is mixed by neon and xenon.Therefore, before charging into discharge gas, must earlier discharge space be evacuated to vacuum state, to keep the purity of discharge gas.Yet, no matter being horizontal, arranges or the trigonometric expression arrangement by traditional display unit, all can't promptly bleed or reach the gas purpose of circulation smoothly.
Summary of the invention
Therefore, the object of the present invention is to provide a kind of plasma display, the channel direction that makes display unit is corresponding to the air vent hole on the panel, to reach the purpose of bleeding rapidly and ventilating.
According to purpose of the present invention, propose a kind of plasma display (Plasma Display Panel PDP), comprising: a plurality of red display unit, it is arranged on the substrate, and forms a plurality of red display unit channels; A plurality of green display units, it is arranged on this substrate, and forms a plurality of green display unit passages; And a plurality of blue display units, it is arranged on this substrate, and forms a plurality of blue display unit passages.Wherein, the direction of those redness, green and blue display unit passage is towards an air vent hole of this substrate corner.
According to the present invention, a kind of plasma display is also proposed, comprising: a plurality of display units, be arranged on the substrate to its matrix form, and the channel direction of those display units formation is towards an air vent hole of this substrate corner.
