Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is described in more detail.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Consult Fig. 1, display device of the present invention comprises backlight module and display panel, display panel comprises spaced array base palte 10 and glass substrate 20, be located at the polaroid 30 of glass substrate 20 outside surface and to be located on array base palte 10 inside surface, with the spaced quantum rod material layer 40 with R, G, B tri-kinds of colors of glass substrate 20, the orientation of quantum rod material layer 40 changes with the voltage swing applied thereon.
In the present embodiment, quantum rod material layer 40 is divided into R quantum rod material layer 41, G quantum rod material layer 42, B quantum rod material layer 43, three is arranged on array base palte 10 inside surface in order in turn, as the mode of R, G, B, R, G, B, three kinds of colors are uniformly distributed, improve color uniformity.
Wherein, quantum rod material layer 40 comprises at least one material in CdSe (cadmium selenide), CdS (cadmium sulfide), InP (indium phosphide), ZnSe (zinc selenide) and ZnS (zinc sulphide).Quantum rod material can absorb the ultraviolet light of short wavelength, and can inspire the light of R, G, B tri-kinds of colors by the adjusted size of quantum rod.
And the exiting surface of backlight module under display panel sends ultraviolet light, in order to excite the quantum rod material layer 40 of display panel, quantum rod material layer 40 is connected with outside control circuit, can the orientation circuit of quantum rod material in control R, G, B quantum rod material layer by external circuit.After specifically backlight module sends ultraviolet light, excite the quantum rod material layer 40 of shades of colour, simultaneously, the orientation that the voltage swing being applied to quantum rod material layer 40 controls its quantum rod is changed by control circuit, quantum rod material layer 40 is subject to the impact of orientation to control the polarization direction of the light inspired, finally by polaroid analyzing function, control the number of bright dipping, to realize the display of RGB tri-look.
As shown in Figure 2, indicate the absorption spectrum A2 of G quantum rod material layer 42 and excite frequency spectrum B2; As shown in Figure 3, indicate the absorption spectrum A2 of G quantum rod material layer 42 and excite frequency spectrum B2, quantum rod material absorbs the ultraviolet light of shorter wavelength in the light injected, and inspires the light of R, G, B tri-kinds of colors.As shown in Figure 4, for the absorption spectrum A of quantum rod material layer 40 be stimulated after the schematic diagram exciting frequency spectrum B, owing to self there is certain orientation in quantum rod, polarized light will be changed into after natural light excites this material, the orientation of quantum rod can be adjusted again by adjusting the size being applied to quantum rod both end voltage, controlling the polarization direction of this exciting light thus.
Preferably, in order to prevent the ultraviolet portion in backlight module from penetrating display device injection, glass substrate 20 penetrates design through uvioresistant, such as can at its plated surface layer protecting film.
Fig. 5 ~ Fig. 7 is the orientation situation of quantum rod material layer 40 under three kinds of different applying voltages.Suppose that the penetration direction of polaroid 30 is the vertical direction in figure, in Fig. 5, the applying voltage at quantum rod material layer 40 two ends is 0, under zero grey menu, the impressed voltage be applied on this quantum rod material layer 40 is zero, at the initial orientation of quantum rod material layer 40, the polarization direction of the rgb light line be stimulated is vertical with the penetrating shaft of polaroid 30, then cannot penetrate, present low grey menu, the black form that namely brightness is minimum; In Fig. 7, the applying voltage at quantum rod material layer 40 two ends is greater than the applying voltage in Fig. 6, Fig. 6 represents under low grey menu, the impressed voltage be applied in this quantum rod is less, the whereabouts direction change degree of quantum rod material layer 40 is less, the ratio that the polarization direction of the rgb light line be stimulated can be mated with the penetrating shaft of polaroid 30 is less, can be also on the low side through the light of polaroid 30, present low grey menu, i.e. Color vector morphological; Fig. 7 represents under high gray picture, the impressed voltage be applied on this quantum rod material layer 40 is larger, the whereabouts direction of quantum rod material layer 40 changes angle close to 90 degree, the polarization direction of the rgb light line be stimulated is parallel with the penetrating shaft of polaroid 30, also can increase through the light of polaroid, present high gray picture, the white form that namely brightness is the highest.
Owing to being provided with quantum rod material layer in display panel of the present invention, display panel eliminates liquid crystal, the lower structure such as polaroid and colored filter, cost declines to a great extent, deflect by applying voltage on quantum rod material layer, instead of the effect of original liquid crystal, and the light self inspired by the orientation of quantum bar material layer with polarization state instead of original lower polaroid effect, three coloured light exciting generation RGB of ultraviolet light are subject to by RGB quantum rod material layer, thus no longer need to realize filter action according to resistance to colored filter, that while ensureing color saturation and work efficiency, has broken away from colored filter penetrates spectrum limitations, by using ultraviolet light as backlight, excite the quantum rod material layer of RGB wave band, optimize display frame, display device has higher color saturation and work efficiency.
The above is only the embodiment of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection domain of the application.
