Abstract
The invention relates to a plasma display panel (PDP) fluorescent powder material, which comprises green fluorescent powder, wherein the green fluorescent powder is formed by mixing any two kinds of materials or more than two kinds of materials in Zn2SiO4:Mn<2+>, YBO3:Tb<3+>, NewZn2SiO4:Mn<2+>, Y, GdAl3(BO3)4:Tb<3+>, Y3Al5O12:Ge<3+>, BaMgAl10O17:Mn<2+> and BaMgA110O17:Mn, the PDP fluorescent powder material also comprises red fluorescent powder and the like. The PDP fluorescent powder material can realize the goal of reducing the brightness decay period of a PDP screen within 8ms under the condition of ensuring the cost, the brightness, the service life and the color purity of the PDP screen. The mixture decay period is reduced to 6ms under the condition of ensuring that the brightness, the color coordinate offset and the service life reliability meet the PDP module group product requirements.
Description
Technical field
The invention belongs to chemical engineering and display device field, be specially the PDP phosphor material powder.
Background technology
PDP normally sends visible light by the electron ion excitated fluorescent powder, and the state characteristic of fluorescent material can impact the life-span of luminous efficiency, colourity, time of response and the product of screen.The red fluorescence powder that common PDP is commonly used is Y, GdBO
3: Eu3+, green emitting phosphor are Zn
2SiO
4: Mn2+, YBO
3: Tb3+, blue colour fluorescent powder are BaMgAl
10O
17: Eu2+.Red fluorescence powder also has Y (P, V) 0
4: Eu3+, Y, Gd
2O
3: Eu3+, Y
20
3: Eu3+, green emitting phosphor also have New Zn
2Si
O4: Mn2+, Y, GdAl
3(BO
3)
4: Tb3+, Y
3Al
5O
12: Ce3+, BaMgAl
10O
17: Mn2+ etc., but because colourity and brightness are all not too suitable, general use less among the common 2DPDP.
Usually the brightness decay cycle of PDP is 9 ~ 10ms, after extinguish in a complete bright zone in other words, need be through time of 10ms nearly, its brightness just can be reduced to peak brightness 10% once, enter " extinguishing " state in general sense.
In common 2D uses, this persistence characteristic of fluorescent material has enough been used, because the television image signal of 60Hz, per field duration is 16.67ms, and the display mode of common AC-PDP is a son formula, and this mode is once full frame discharge after finishing full frame addressing, all picture points are lighted simultaneously, extinguish from being illuminated to, can be calm in a field duration, finish, this also is that PDP is in the reason that is better than liquid crystal aspect dynamic definition and the hangover.
But during as switch spectacle 3D, because in the cycle of every 16.67ms, to finish the demonstration of two pictures of right and left eyes respectively, field frequency will double in other words, each cycle of simple eye has shortened to 8.83ms, use the common phosphors will be so because of when showing next width of cloth picture, the brightness of a last width of cloth picture does not also lower fully, the effect of seeing is that the shadow of a last width of cloth picture remains on this width of cloth picture, form the cross-talk phenomenon of right and left eyes picture, cause the decline of 3D rendering quality.
The brightness decay cycle of PDP is to mix decision by the characteristics of luminescence of three kinds of fluorescent material, the fading period of a certain display area, determine jointly that by the weight of three kinds of pure colors in brightness of the color of forming it and the fluorescent material fading period characteristic of its color calculation formula is: τ white=Lred * τ red+Lgreen * τ green+Lblue * τ blue.For the zone of a white, red fluorescence powder generally is 0.25 ~ 0.3 to the contribution rate of brightness, and green generally is 0.6 ~ 0.65, and blueness generally is 0.09 ~ 0.11.
In general it is the longest to go up the brightest white portion fading period of screen, because green and redness account for the luminance weights maximum, so the performance of green emitting phosphor is also maximum to the influence of cross-talk problem.
Red fluorescence powder uses Y, GdBO
3: luminous efficiency is the highest during Eu3+, has used the PDP unit of this fluorescent material to extinguish under 100% peak brightness condition, and fading period generally is 10ms, Y (P, V) 0
4: the luminous efficiency of Eu3+ is lower, it by electron excitation after luminous peak brightness can only reach Y usually, 65% of GdBO3:Eu3+, but its fading period is shorter, 4ms only.Other two kinds: Y, Gd
2O
3: Eu3+, Y
20
3:The fading period of Eu3+ also has only 4ms.
Red fluorescence powder adopts Y, GdBO
3: Eu3+ is main, in order to improve brightness, and mixed powder material according to a certain percentage, as selecting scheme more cheaply, also can be still with Y, GdBO
3: Eu3+ is main, mixes with Y
2O
3: the fluorescent material of Eu3+.Green emitting phosphor need be adjusted to the Mn content in the ZSM series material that uses below 30%, lower Mn content can improve decay time(replicative cycle), the fading period of one of main raw of considering green emitting phosphor simultaneously is long, the YAG series that the cycle that should change into is shorter, perhaps BaMgA1
100
17: Mn.
