Abstract
The invention discloses a kind of display base plate, include color film layer, described color film layer includes red pixel, green pixel and blue pixel；Wherein, doped with D π A structure dye molecule in blue pixel.Use the present invention to be capable of a certain degree of colour cast to compensate.
Description
Technical field
The present invention relates to display field, particularly relate to a kind of display base plate and display device.
Background technology
Matrix form public electrode (Matrix-Vcom) is a kind of relatively common array design, and it can increase common electric voltage
(Vcom) homogeneity, reduces the generation of greening (greenish) phenomenon.But, this design there is also drawback: owing to lead to
Cross deposition metal level and turn on the public electrode of adjacent two pixels, and the position of the metal level deposited just corresponding blue pixel,
Which results in the aperture opening ratio between different pixels inconsistent, finally produce color offset phenomenon.
Summary of the invention
In view of this, present invention is primarily targeted at a kind of display base plate of offer and display device, can be to display dress
Color offset phenomenon in putting compensates.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:
A kind of display base plate, includes color film layer, and described color film layer includes red pixel, green pixel and blue picture
Element；Wherein, doped with D-π-A structure dye molecule in described blue pixel.
Wherein, described D-π-A structure dye molecule is chosen from following structure:
Further, above-mentioned display base plate is color membrane substrates；Or, above-mentioned display base plate is the array being integrated with color film layer
Substrate.
A kind of display device, including display base plate as above.
By technique scheme it can be seen that by blue pixel adulterate D-π-A structure dye molecule, utilize D-π-
The photoelectric transformation efficiency of A structure dye molecule, it is possible to achieve a certain degree of colour cast compensates.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of display base plate of the present invention.
Detailed description of the invention
The invention provides a kind of display base plate, as it is shown in figure 1, display base plate includes: substrate 1, black matrix 2, color film layer
With transparency conducting layer 6；Described color film layer includes red pixel 3, green pixel 4, blue pixel 5；Wherein, described blue pixel 5
In doped with D-π-A structure dye molecule 7.
Another embodiment of the present invention provides another kind of display base plate, i.e. by COA (Color Filteron
Array) array base palte that technology is formed, will be produced on array base palte and is formed by color film layer.In battle array based on COA technology
In row substrate, doped with D-π-A structure dye molecule in the blue pixel of color film layer.
The display base plate that the present invention provides is applied to liquid crystal display, OLED display etc..
Explanation D-π-A structure dye molecule carries out the principle of chromatic compensation below.
Being presented above the structural formula of three D-π-A structure dye molecules, these three molecule is respectively as follows:
Compound 1:2-cyano group-3-{6-{4-[N, N-bis-(4-Hexyloxy-phenyl) amido] phenyl }-4,4-dihexyl-4H-
Two thiophene [2,1-b:3,4-b '] pentalene } acrylic acid；
Compound 2:2-cyano group-3-{6-{4-[N, N-bis-(4-Hexyloxy-phenyl) amido] phenyl }-4,4-dihexyl-4H-
Two thiophene [2,1-b:3,4-b '] pentalene-2-one base } acrylic acid；
Compound 3:2-cyano group-3-{6-{4-[N, N-bis-(4-Hexyloxy-phenyl) amido] phenyl }-4,4-dihexyl-4H-
Two thiophene [2,1-b:3,4-b '] thiophene cough up-} acrylic acid.
Wherein, electron withdraw group i.e. cyano group and carboxyl firmly adsorb on color film, and electronics is sent to through pi-conjugated system
There is energy level transition when reaching triaryl amine group, thus launch the light radiation of certain wavelength, finally realize colour cast and compensate.
Blueness to display floater and traditional Matrix-Vcom panel doped with D-π-A structure dye molecule below
The transmitance of pixel compares.
An example according to the present invention, on the premise of aperture opening ratio is consistent, is obtained doped with D-π-A by simulation experiment
The display floater of structure dye molecule and the transmitance of the blue pixel of traditional Matrix-Vcom panel；Wherein, doping D-π-
After A structure dye molecule, the transmitance of blue pixel is 6.73, and the passing through of the blue pixel of traditional Matrix-Vcom panel
Rate is 6.44, it is seen then that after doping D-π-A structure dye molecule, the transmitance of blue pixel improves about 4.5%, thus realizes
A certain degree of colour cast compensates.
Present invention also offers a kind of display device, it includes display base plate as above.
In embodiments of the present invention, above-mentioned display device can be but not limited to liquid crystal display, liquid crystal panel, liquid crystal
The display devices such as TV, OLED (organic light emitting diode) display.
The above, only presently preferred embodiments of the present invention, it is not intended to limit protection scope of the present invention.
