Display device, its operation principle are, and filter panels shinny by the quanta point material in excitation optical filtering panel
In each color pixel cell it is adjacent with the pixel cell of other two colors, therefore, existing any type of liquid crystal
The problem of color cross-talk be present in display device.Based on this, it is proposed that the technical scheme of the embodiment of the present invention.
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below by embodiment it is required use it is attached
Figure is briefly described, it should be apparent that, for those of ordinary skills, do not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Referring to Fig. 2, Fig. 2 be liquid crystal display device provided in an embodiment of the present invention structural representation, the embodiment of the present invention
The liquid crystal display device of offer, using the optical filtering panel of " pixel of three color four ", and coordinate the exciting light of two colors, can carry on the back
In the case that the shooting angle of radiant is excessive, still ensure that the light of each color will not be by crosstalk.
Specifically, the liquid crystal display device of this programme includes:Light source mechanism 21, liquid crystal cell 22 and optical filtering panel 23, wherein,
Liquid crystal cell 22 and optical filtering panel 23 are arranged in parallel, also, each pixel cell of the corresponding optical filtering panel 23 of liquid crystal cell 22
It is provided with switch.In this scenario, light source mechanism 21 is provided with blue light source 211 and red-light source 212, wherein, blue light source
211 are used to provide blue excitation light, and red-light source 212 is used to provide red exciting light.Optical filtering panel 23 is provided with red pixel
Unit 231, green pixel cell 232 and transparent pixels unit 233.
Wherein, the adjacent red pixel cell 231 in the both ends of each green pixel cell 232, each transparent pixels unit
Also adjacent red pixel cell 231, one end of each red pixel cell 231 abut green pixel cell at 233 both ends
232, other end adjoining transparent pixels unit 233.Also, green pixel cell 232 is provided with green quanta point material, for connecing
Blue excitation light by blue light source 211 is shinny;Red pixel cell 231 is provided with optical filter, and optical filter is used to swash in red
It is shinny under luminous irradiation;Transparent pixels unit 233 is used for the blue excitation light of transparent transmission blue light source 211, obtains blue light.
According to the position relationship between above-mentioned pixel cell, and the attribute of the pixel cell of each color, pass through blueness
The green quanta point material in light irradiation green pixel cell 232 is excited, green quanta point material is excited shinny by blue light.Its
In, because the both ends of green pixel cell 232 are red pixel cells 231, and the optical filter in red pixel cell 231, only
By red light, the light of other wavelength is filtered out, and therefore, even if blue excitation light shooting angle is excessive, is irradiated to red picture
It plain unit 231, can also be filtered out by the optical filter in red pixel cell 231, therefore, crosstalk will not be produced.Likewise, blueness swashs
Luminous irradiation transparent pixels unit 233, and be emitted from transparent pixels unit 233, obtain blue light.And it can be seen from foregoing description,
The both ends of transparent pixels unit 233 are also red pixel cell 231, and therefore, blue light also will not be by crosstalk.Shone by red exciting light
Red pixel cell 231 is penetrated, and through the optical filter outgoing in red pixel cell 231, obtains feux rouges.Due to red pixel list
First 231 both ends are green pixel cell 232 and transparent pixels unit 233 respectively, and the wavelength of feux rouges is grown compared with green glow, therefore, i.e.,
Make red exciting light shooting angle excessive, be irradiated to green pixel cell 232, red exciting light can not also excite green quantum dot
Material is shinny, even and if red exciting light is irradiated to transparent pixels unit 233, resulting emergent light also feux rouges, institute
With also will not be by crosstalk.
As can be seen here, the liquid crystal display device described in this programme, even if the shooting angle of back light is excessive, it is irradiated to mesh
When marking the adjacent pixel cell of pixel cell, also it will not cause each color will not be by crosstalk so that liquid crystal display device institute
The color of image corrigendum of display, and then the usage experience of user can be improved.
In addition, on the basis of foregoing description, transparent pixels unit 233 can be with transparent transmission red exciting light, i.e. red swashs
It is luminous to be emitted by red pixel cell 231 and transparent pixels unit 233, feux rouges is obtained, so as to improve feux rouges
Light extraction efficiency.
Further, because green quanta point material is excited by blue excitation light shinny, caused light scatters,
A part of light is scattered to screen orientation, and this part light can be used directly, and another part light scatters to the direction of liquid crystal cell 22,
It can not be utilized, so as to reduce the light extraction efficiency of green glow.In view of this, on the basis of said structure, in optical filtering panel 23
The end face of green pixel cell 232 towards liquid crystal cell 22 is provided with reflecting layer, and the reflecting layer is dichroism reflecting layer, only to green
Optical band has reflection characteristic, has high-permeability for the light of its all band.Thus, blue excitation light can be directed through,
And blue excitation light excites green quanta point material shinny, when being scattered to the direction of liquid crystal cell 22, screen orientation is reflected to, weight
Newly it is utilized, so as to improve the light extraction efficiency of green glow.
