Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, the invention provides a kind of autoluminescence module, comprising:
The first substrate 1 be oppositely arranged and transparent second substrate 2, and be arranged on the luminescent device being no less than between first substrate 1 and this second substrate 2;
Wherein, each luminescent device all has an annular seal space, and the inwall of annular seal space is provided with excitation layer 4, and is filled with the energizing gas that can excite this excitation layer 4 luminescence.
In actual applications, excitation layer 4 can be fluorescence coating or quantum dot layer, and energizing gas can be tritium gas.For quantum dot layer (fluorescence coating principle is identical), the charged particle (β particle) that tritium gas sends when decaying can bombard quantum dot layer, thus makes quantum dot layer output photon, realizes luminous.
Based on above-mentioned principle, the autoluminescence module of the present embodiment, when not having power supply energy supply, can reach several years by self-luminescence, and being specially adapted to be assemblied in needs in the display device of low-power consumption.
Particularly, as shown in Figure 1, the annular seal space of the present embodiment comprises: epicoele wall (i.e. second substrate 2), chamber, side wall 3 and cavity of resorption wall (i.e. first substrate 1);
Wherein, preferably, chamber, side wall 3 is acute angle with the angle of second substrate 2, makes the light in annular seal space after getting to chamber, side wall 3, is easy to reflect on second substrate 2, and brightness of illumination is got a promotion.
In the product of reality, chamber, the side wall 3 of the present embodiment can be integrated with first substrate 1 or second substrate 2.For first substrate, the present embodiment can pass through to form cavity structure to first substrate carrying out etching, to form chamber, side wall further on the first substrate.
In addition, the quantum dot layer 4 of the present embodiment is formed on chamber, side wall 3, thus can not shut out the light through second substrate 2.
Certainly, for improving the brightness of luminescent device further, the present embodiment can arrange reflection horizon 5 between excitation layer 4 and chamber, described side wall 3, and this reflection horizon can by can making, as metal material the material that light plays reflex.
Be more than the autoluminescence module of the present embodiment, the light that excitation layer produces can concentrate reflection on second substrate, makes autoluminescence module have higher brightness.
Accordingly, another embodiment of the present invention also provides a kind of display device comprising above-mentioned autoluminescence module, because this autoluminescence module can not produce energy consumption, therefore the display device of the present embodiment has higher cruising time, can meet the user demand of some special screnes.
Particularly, with reference to figure 2, in the present embodiment, the second substrate of autoluminescence module is the array base palte 30 of display device, and this array base palte 30 comprises:
To be arranged on second substrate and away from multiple thin film transistor (TFT) (not shown) of luminescent device 21 side and multiple light valve 31; Wherein, light valve 31 and thin film transistor (TFT) one_to_one corresponding, and controlled by thin film transistor (TFT).
In actual applications, the opening angle of display device by driving thin film transistor (TFT) to control light valve 31 of the present embodiment, thus change the transmittance of the light of below autoluminescence module, obtain the display frame of different GTG.
Particularly, Fig. 3 is the vertical view of display device, and each luminescent device 21 in figure on autoluminescence module can control transmittance by the corresponding light valve 31 of on array base palte 30.If display device of the present invention presents colour picture by autoluminescence module, then each luminescent device 21 is all a sub-pixel in corresponding display device.Be provided with the quantum dot layer of different special materials in luminescent device 21 annular seal space, after energizing gas excites, the light of a kind of base color in red R, green G, blue B can be sent.If display device of the present invention presents sprite by autoluminescence module, then in Fig. 3, luminescent device 21 can one or more sub-pixels of corresponding display device, compared to the display of colour picture, more simple to the structural requirement of autoluminescence module.
Here need to be described, the light valve shown in Fig. 3 is MEMS structure, only for exemplary introduction.Light valve as other feasible program the present embodiment also can adopt liquid crystal structure, and owing to being prior art, the present invention is no longer described in detail.
In addition, preferably, display device of the present invention can also use traditional passive illuminating module as light source further, describes in detail below to the association schemes of autoluminescence module and passive illuminating module.
As shown in Figure 4, the autoluminescence module of display device of the present invention comprises multiple luminescent device, and the annular seal space of each luminescent device comprises: epicoele wall 2, chamber, side wall 3 and cavity of resorption wall 1.
Wherein, the cavity of resorption wall 1 of annular seal space is as the first substrate of autoluminescence module, and this first substrate is formed by transparent material.
Arrange passive illuminating module 6 further in first substrate backward luminous device side, luminous after this passive illuminating module 6 is energized, the light of generation can through transparent first substrate 1.
Here it should be noted that, if for the autoluminescence module that can send colored light, the color of the light of luminescent device is then arrived by passive illuminating module, the solid colour of the light sent after exciting with the excitation layer of this luminescent device, thus make the light of autoluminescence module and passive illuminating module form the superposition of same color, and then improve the display quality of display device.
When stating scheme in realization, passive illuminating module 6 comprises a colored filter 61, is arranged on the side of autoluminescence module.The light of passive illuminating module 6, after colored filter 61, obtains the color corresponding with the luminescent device of autoluminescence module.
In actual applications, user can close passive illuminating module, makes display device only using autoluminescence module as light source, to extend cruising time.Certainly, the cruising time of display device is considered if do not need, user can open passive illuminating module, display device is shown as light source jointly by autoluminescence module and passive illuminating module, compared to traditional display device only arranging passive luminous mould, there is higher display brightness and display quality.
Certainly, be attached in actual display device, the intelligence that the present embodiment also can realize light source switches.For mobile phone, if configure autoluminescence module of the present invention, user just checks the time by mobile phone, then, before mobile phone unlocks, can only use passive illuminating module to light screen, thus saves electric quantity consumption.As can super low-power consumption be met when being applied in outdoor products, the demand of overlength display.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle of the present invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
