Description
The present invention relates to a kind of plasma scope, particularly a kind of area coverage of fluorescence coating of can adjusting is to improve the colour plasma display of colour temperature (color temperature).
Colour plasma display (Plasma Display Panel, PDP) be to be arranged in a combination by hundreds thousand of individual display units of hundreds of microns approximately, its principle of luminosity is to apply a voltage to make ionized gas discharge to produce ultraviolet ray, and when the different fluorophor of ultraviolet irradiation, just can make this fluorophor respectively send the three primary colors of light respectively: red, green and blueness.Generally speaking, the color that fluorophor sent is to depend on its employed fluorescent material.When fluorescent material is yttrium borate salt ((Y, Gd) BO
3), wherein and add erbium (Eu), then can produce red fluorescence as luminescence center; When fluorescent material is zinc sulfate (Zn
2SO
4), wherein and add manganese (Mn), then can produce green fluorescence as luminescence center; And work as fluorescent material is magnesium aluminate barium salt (BaMgAl
14O
23), wherein and add erbium (Eu), then can produce blue-fluorescence as luminescence center.
But, owing to the blue-fluorescence that utilizes fluorophor to send has the phenomenon that the color deterioration takes place Yin Re.Therefore the method for improving the luminescent quality of colour plasma display at present is the discharge space increasing with blue-fluorescence, to increase the area coverage of its fluorophor, use the proportion of adjusting redness, green and blue-fluorescence that colour plasma display sent, make colour temperature be promoted to 11000 ° of K by 7000 ° of K.
With reference to Fig. 1, Fig. 1 is the schematic diagram of known colour plasma display 10.Known colour plasma display 10 includes two parallel first substrate 12 and second substrates 14, one ionized gas (not shown) is filled between first, second substrate 12,14, a plurality of first electrodes 18, a plurality of second electrodes 20 and a plurality of address electrode (address electrode) 22.Wherein each first electrode 18 and second electrode 20 are parallel to each other being arranged on first substrate 12, and each address electrode 22 is to be arranged on second substrate 14 with the perpendicular mode of first electrode 18 and second electrode 20.
Each first electrode 18, second electrode 20 are kept electrode 181,201 and are made up of the auxiliary electrode 182,202 that chromium/copper/chromium (Cr/Cu/Cr) three-layer metal material is constituted by what the ITO material constituted, but it is bigger wherein to keep the visible light resistance value that electrode 181,201 can permeation parts, and auxiliary electrode 182,202 has good conductivity, can effectively increase the conductivity of first electrode 18 and second electrode 20.
Colour plasma display 10 includes a dielectric layer 24 in addition and covers on first substrate 12; one protective layer 26 is covered on the dielectric layer 24; a plurality of barrier ribs (rib) 28 are located on second substrate 14 in the mode that is parallel to each other; be used for isolating two adjacent address electrodes 22; with the discharge space (discharge space) 30 that forms a plurality of strips; and one fluorescence coating 32 be coated on each bar discharge space 30 bottom and barrier rib 28 sidewalls, be used for producing redness, green or blue light.Wherein each bar discharge space 30 all includes a plurality of display units (unit display element) 34, is arranged between first substrate 12 and second substrate 14 and all display units 34 are modes with matrix.
In addition, all strip discharge spaces 30 are made of a plurality of discharge space groups, and each discharge space group includes the red discharge space 30R of a coating red fluorescence layer 32R, the green discharge space 30G and of a coating green fluorescence layer 32G and is coated with the blue discharge space 30B of blue fluorescent body 32B.Therefore can form a plurality of red display unit 34R in the red discharge space 30R, can form a plurality of green display unit 34G in the green discharge space 30G, can form a plurality of blue display unit 34B in the blue discharge space 30B.Red display unit 34R, a green display unit 34G and a blue display unit 34B are commonly referred to as a pixel (pixel).
As previously mentioned, in order to improve the blue-fluorescence quality that colour plasma display 10 is sent, known method is that the A/F with red discharge space 30R is designed to the narrowest mostly, and the A/F of green discharge space 30G is designed to moderate 1.2 times of being about red discharge space 30R A/F, last be designed to the A/F of blue discharge space 30B the wideest again, 1.6 times of A/F that are about red discharge space 30R, make the space minimum of red display unit 34R, the space that makes blue display unit 34B is used and is adjusted the redness that colour plasma display 10 is sent for maximum, the proportion of green and blue-fluorescence.Thus, the machining surface that is coated on the blue fluorescent body 32B of blue display unit 34B can be maximum, and coat the machining surface meeting minimum of the red fluorescence layer 32B of red display unit 34R.Therefore when ionized gas discharge generation visible light, the proportion of the blue-fluorescence that is sent can be bigger, make redness, green mix knifeedge with blue-fluorescence and reach preferable white balance (white balance) state, and then the colour temperature of colour plasma display 10 is promoted to about 11000 ° of K.

Fig. 1 is the schematic diagram of known colour plasma display.
Fig. 2 is the schematic diagram of the colour plasma display of first embodiment of the invention.
Fig. 3 is the schematic diagram of the colour plasma display of second embodiment of the invention.
With reference to Fig. 2, Fig. 2 is the schematic diagram of first embodiment of colour plasma display 40 of the present invention.Colour plasma display 40 includes a back plate 42 and a header board 44, and header board 44 is to be arranged on abreast on the plate 42 of back.A plurality of first electrodes 46, second electrode 48 are located on the header board 44, and a dielectric layer 52 also covers on the header board 44, and last, a protective layer 54 covers on the dielectric layer 52.Wherein have a gap between header board 44 and the back plate 42, so that an ionized gas is filled between back plate 42 and the header board 44.
In addition, there are a plurality of address electrodes 50 to place on the plate 42 of back.Each first electrode 46 and second electrode 48 are to be arranged on the header board 44 in mode parallel to each other, and each address electrode 50 is to be arranged on the plate 42 of back with first electrode 46 mode vertical with second electrode 48.First electrode 46 and second electrode 48 all keep electrode 461,481 by one and 462,482 of auxiliary electrodes are formed.Wherein keep electrode the 461, the 481st, be used for carrying out surface discharge, have light transmission, can use ITO (Indium Tin Oxide) or SnO (Tin Oxide) as the material of keeping electrode 461,481, but its resistance value is bigger.Auxiliary electrode the 462, the 482nd can increase the conductivity of first electrode 46 and second electrode 48, has good conductivity, can use chromium/copper/chromium (Cr/Cu/Cr) three-layer metal or silver (Ag) metal as material.
Also be provided with the first bottom barrier rib (bottom rib), the 62 and second bottom barrier rib 63 on back plate 42 surfaces, be respectively formed on the back plate surface of red discharge space 60R and green discharge space 60G.These " bottom barrier ribs " are not to be used for " obstruct " different fluorophor, but use and the barrier rib identical materials, and form in same manufacture process.The first bottom barrier rib 62 is different with the thickness of the second bottom barrier rib 63, to form the discharge space of different depth.Do not form the bottom barrier rib among the blue discharge space 60B, so the degree of depth of blue discharge space 60B is the darkest, green discharge space 60G takes second place, and red discharge space 60R is the most shallow.
As shown in Figure 2, blue fluorescent body 58B is barrier rib 56,57 sidewall surfaces of coating plate 42 surfaces, the pairing back of blue discharge space 60B and being centered around blue discharge space 60B, is used for producing a blue ray.Green fluorescence layer 58G be coated among the green discharge space 60G the second bottom barrier rib 63 surface and around barrier rib 57,59 sidewall surfaces of green discharge space 60G, be used for producing a green light.Red fluorescence layer 58R be coated among the red discharge space 60R the first bottom barrier rib 62 surface and around barrier rib 59,61 sidewall surfaces of red discharge space 60R, be used for producing a red light.
The present invention utilizes the mode of printing to make these to be parallel to each other, equidistantly and the barrier rib 56 of different depth.At first at back plate 42 printing one deck barrier rib materials, be used to define the pattern (pattern) of each discharge space 60, earlier form first to fourth barrier rib 56,57,59,61 with (or etching) method that sandblasts, the height of those barrier ribs is suitable, makes the degree of depth of each discharge space identical.Then in the groove of red discharge space 60R, be covered with the wet type photoresist, remove barrier rib green and blue discharge space 60G, 60B base section with the method for sandblasting again, arrive desired depth up to green discharge space 60G.In the groove of red and green discharge space 60R, 60G, be covered with photoresist layer subsequently, remove the interior barrier rib material in blue discharge space 60B bottom with the method for sandblasting again, to produce the blue discharge space 60B of desired depth.The residual barrier rib material in red discharge space 60R bottom is defined as the first bottom barrier rib, and the residual barrier rib material in green discharge space 60G bottom is defined as the second bottom barrier rib.Last be coated with identical but the fluorescence coating 58 that color is different of a thickness respectively at each discharge space 60 again.
With reference to Fig. 2, in this embodiment, because the red discharge space 60R degree of depth is the most shallow, the barrier rib sidewall surfaces that therefore can be coated with red-emitting phosphors 58R among the red discharge space 60R is long-pending minimum, and the degree of depth of blue discharge space is the darkest, and the barrier rib sidewall surfaces that therefore can be coated with blue emitting phophor 58B among the blue discharge space 60B is long-pending maximum.When ionized gas discharge generation visible light, the proportion of the blue-fluorescence that colour plasma display 40 is sent can increase, therefore pass through the change of red, green and blue-fluorescence mixed proportion, just can reach preferable white balance state, the colour temperature of colour plasma display 40 is promoted to about 11000 ° of K.Because the restriction on the blue emitting phophor material makes the luminance of blue emitting phophor relatively poor.For the luminous efficiency that makes blue emitting phophor improves, therefore, the area maximum that is designed to blue emitting phophor of present embodiment, the area of green-emitting phosphor takes second place, the area minimum of red-emitting phosphors.On the actual design, so long as the area of blue emitting phophor gets final product greater than the area of red-emitting phosphors, the area of green-emitting phosphor can be with the area of blue emitting phophor identical or littler can.
When the size of colour plasma display is dwindled, all discharge spaces all are required to dwindle, a plurality of barrier ribs still can be kept equally spaced arrangement mode, and then adjust the area coverage of the fluorescence coating 58 in each discharge space 60 by the degree of depth of each discharge space 60, therefore do not need excessively to shorten the spacing between a plurality of barrier ribs.So, not only can reduce the difficulty in the making, can also avoid ionized gas in the discharge space to disturb (cross talk) to adjacent discharge space and influence the electrical performance of colour plasma display 40.
In addition, by changing the coating thickness of fluorescence coating, also can adjust the area coverage of the fluorescence coating in each discharge space.
