The luminescent device of one one exemplary embodiment according to the present invention is described with reference to Fig. 1 to 5.
With reference to Fig. 1, the luminescent device 100 of an one exemplary embodiment comprises luminescent panel 10 and is arranged in luminescent panel 10 fronts and with a distance and luminescent panel 10 isolated light diffusers 12, described distance can be a preset distance.
With reference to Fig. 2 and 3, in containment member 18, first and second substrates 14 and 16 each be divided into active region and around non-active region of active region, in fact visible light is launched from active region.Comprise inner surface that the electron emission unit 26 of a plurality of electronic emission elements is arranged on first substrate 14 at the active region place, the luminescence unit 28 that is used for visible emitting is arranged on the inner surface of second substrate 16 at the active region place.
28 second substrates 16 thereon of luminescence unit can be the prebasal plates of luminescent panel 10, and 26 first substrates 14 thereon of electron emission unit can be the metacoxal plates of luminescent panel 10.
The material of emitting electrons formed when electron emission region 30 was formed at around it by electric field under vacuum environment, such as carbon-based material or nano-sized materials.For example electron emission region 30 can comprise and is selected from carbon nano-tube, graphite, gnf, diamond, diamond-like-carbon, fullerene (C
60), the material of silicon nanowires and the group that constitutes thereof at least a.Perhaps, electron emission region can be formed by the sharp-pointed sharp structure that molybdenum base material or silica-base material are made.
In said structure, cathode electrode 32, a gate electrode 34 and be positioned at negative electrode and the electron emission region of an intersection region of gate electrode 32 and 34 30 forms single electronic emission element.An electronic emission element can be corresponding to the single pixel region of luminescent panel 10.Perhaps, two or more electronic emission elements can be corresponding to the single pixel region of luminescent panel 10.
Sept 44 is arranged between first and second substrates 14 and 16, and it can bear the pressure that is applied to vacuum tank or pressure and can keep gap between first and second substrates 14 and 16 equably.Sept 44 is positioned at outside negative electrode and gate electrode 32 and 34 zones intersected with each other.For example, sept 44 can be positioned at outside the relative bight of intersection region.Sept 44 can form has multiple structure.For example, in one embodiment, sept 44 has quadrangular structure as shown in Figure 3.
When turntable driving voltage is applied to negative electrode or gate electrode 32 or 34, data drive voltage is applied to another in negative electrode or gate electrode 32 or 34, and anode voltage is when being applied to anode electrode 38, driven for emitting lights panel 10.
The pixel that voltage difference between negative electrode and gate electrode 32 and 34 is equal to or greater than threshold voltage forms electric field around being in electron emission region 30, so electronics is from electron emission region 30 emissions.Institute's electrons emitted attract by the anode voltage that is applied to anode electrode 38 and with the collision of the counterpart of phosphorescent layer 40, excite phosphorescent layer 40 thus.
In above-mentioned luminescent panel 10, sept 44 forms the height H (see figure 3) with 5-30mm.According to the height of sept 44, first and second substrates 14 and 16 distances with 5-30mm are spaced apart from each other.
In one embodiment, when the height of sept 44 during less than 5mm, even in vacuum tank, also be easy to generate arc discharge, so anode electrode 38 can not receive the above anode voltage of 5kV because be applied at anode voltage under the situation of anode electrode 38 less than 5kV.Therefore, the high voltage stability degradation of luminescent panel 10 and be difficult to realize enough brightness.

As shown in table 1, the resistance to arc discharge that comparative example 1 and 2 performances are gone on business (in the table *), example 1 and comparative example 3 and 4 show the satisfied resistance to arc discharge (zero in the table), and example 2 to 8 shows the excellent resistance to arc discharge (◎ in the table).In addition, as shown in table 1, the minimum range between luminescent panel and the light diffuser enlarges markedly in comparative example 3 and 4.
Especially, even under the anode voltage of 2-3kV is applied to the situation of the anode electrode in comparative example 1 and 2, also produce arc discharge.Yet, under the anode voltage of 7kV, 12kV and 17kV is applied to the situation of the anode electrode in each example 1,4 and 8 respectively, do not produce arc discharge.
As mentioned above, because can be applied to anode electrode 38, so the luminescent device 100 of present embodiment can be realized high brightness greater than the anode voltage of 7kV.In addition, the high voltage stability of luminescent panel 10 strengthens by preventing the arc discharge in the vacuum tank, and the efficient of luminescent device 100 (brightness/power consumption) can improve by minimizing or reduce the light loss that light diffuser 12 causes.
In addition, form sept 44 of the present invention and make that the width of a side is 0.2-5mm.With reference to Fig. 3 and 4, sept 44 can form has the quadrangular structure.At least one side in second side (for example vertical side) of first side of sept 44 (for example horizontal side) and sept 44 forms the width with 0.2-5mm.In Fig. 4, L1 indicates the width of first side, and L2 indicates the width of second side.
In one embodiment, when a side of sept 44 has width less than 0.2mm, be difficult to sept 44 is installed on electron emission unit 26 or the luminescence unit 28, and the crystallized ability of sept 44 descends.In addition, in one embodiment, when a side of sept 44 had width greater than 5mm, the brightness uniformity of luminescent panel 10 reduced.Therefore, in according to one embodiment of the invention, the distance between luminescent panel 10 and the light diffuser 12 increases or the transmissivity of light diffuser 12 reduces to improve brightness uniformity.
In an one exemplary embodiment, light diffuser 12 has greater than 80% transmissivity to minimize or to reduce light loss.When a side of sept 44 has the width that is less than or equal to 5mm, can use light diffuser 12 with 80% above transmissivity.
In addition, forming sept 44 makes the gross area that is occupied by sept 44 in active region 46 (Fig. 5) satisfy following condition.The sept 44 that Fig. 5 schematically shows the active region 46 of first and second substrates 14 and 16 and is arranged in active region 46.With reference to Fig. 5, in the luminescent panel 10 of present embodiment, sept 44 forms and satisfies following conditions:
0.1≤(S2/S1)×100≤1.5，
Here S1 represents the size of active region 46, and S2 is illustrated in the gross area that is occupied by sept 44 in the active region 46.
When the area of active region 46 and sept 44 than less than 0.1 the time, the mounting process of sept 44 must be accurately and the crystallized ability of sept 44 descend.When the area of active region 46 and sept 44 than greater than 1.5 the time, the transmissivity that the brightness uniformity of luminescent panel 10 descends and therefore needs to increase the distance between luminescent panel 10 and the light diffuser 12 or reduce light diffuser 12.
For example, if active region 46 is of a size of about 144cm in 7 inches luminescent panel 10
2, and have 12 septs 44 to be positioned at active region 46, and each first side of sept 44 and each second side have the width of 2mm, and then the gross area that is occupied by sept 44 is 48mm
2(0.48cm
2), and the area ratio of active region 46 and sept 44 is about 0.33%.The gross area that occupies by sept 44 can be by control interval thing 44 size and number and suitably changing.
Above-mentioned luminescent panel 10 can apply be higher than 7kV anode voltage to anode electrode 38, and in an one exemplary embodiment, therefore the anode voltage that can apply 7-17kV can realize about 10000cd/m at the core of active region 46 to anode electrode 38
2High-high brightness.
