Abstract
The invention discloses a display substrate which comprises a color film; the color film contains red pixels, a green pixel and a blue pixel, wherein D-Phi-A structure dye molecules are doped in the blue pixels. With the adoption of the display substrate, a certain degree of color error compensation can be realized.
Description
Technical field
The present invention relates to demonstration field, relate in particular to a kind of display base plate and display device.
Background technology
Matrix form public electrode (Matrix-Vcom) is a kind of more common Array Design, and it can increase the homogeneity of common electric voltage (Vcom), reduces the generation of greening (greenish) phenomenon.But, also there is drawback in this design: owing to will passing through the public electrode of adjacent two pixels of depositing metal layers conducting, and the metal level position of corresponding blue pixel just in time of deposition, this has just caused the aperture opening ratio between different pixels inconsistent, finally produces color offset phenomenon.
Summary of the invention
In view of this, fundamental purpose of the present invention is to provide a kind of display base plate and display device, can the color offset phenomenon in display device be compensated.
For achieving the above object, technical scheme of the present invention is achieved in that
A display base plate, includes color rete, and described color rete includes red pixel, green pixel and blue pixel; Wherein, in described blue pixel doped with D-π-A structure dye molecule.
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 base palte that is integrated with color rete.
A display device, comprises display base plate as above.
By technique scheme, can be found out, by D-π-A structure dye molecule that adulterates, utilize the photoelectric transformation efficiency of D-π-A structure dye molecule in blue pixel, can realize colour cast compensation to a certain degree.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of display base plate of the present invention.
Embodiment
The invention provides a kind of display base plate, as shown in Figure 1, display base plate comprises: substrate 1, black matrix 2, color rete and transparency conducting layer 6; Described color rete comprises red pixel 3, green pixel 4, blue pixel 5; Wherein, in described blue pixel 5 doped with D-π-A structure dye molecule 7.
Another embodiment of the present invention provides another kind of display base plate, and the array base palte forming by COA (Color Filteron Array) technology is about to color rete and is produced on array base palte and forms.In the array base palte based on COA technology, in the blue pixel of color rete doped with D-π-A structure dye molecule.
Display base plate provided by the invention is applied to liquid crystal display, OLED display etc.
The following describes the principle that D-π-A structure dye molecule carries out colourity compensation.
The structural formula that has provided three D-π-A structure dye molecules above, these three molecules are respectively:
Compound 1:2-cyano group-3-{6-{4-[N, N-bis-(the own oxygen base of 4-phenyl) amido] phenyl }-4,4-dihexyl-4H-bis-thiophene [2,1-b:3,4-b '] pentalene } acrylic acid;
Compound 2:2-cyano group-3-{6-{4-[N, N-bis-(the own oxygen base of 4-phenyl) amido] phenyl }-4,4-dihexyl-4H-bis-thiophene [2,1-b:3,4-b '] pentalene-2-mono-base } acrylic acid;
Compound 3:2-cyano group-3-{6-{4-[N, N-bis-(the own oxygen base of 4-phenyl) amido] phenyl }-4,4-dihexyl-4H-bis-thiophene [2,1-b:3,4-b '] thiophene cough up-acrylic acid.
Wherein, electron withdraw group is that cyano group and carboxyl are firmly adsorbed on color film, and electronics, while rolling into a ball through the transmission arrival triarylamine of pi-conjugated system, energy level transition occurs, thereby launches the optical radiation of certain wavelength, finally realizes colour cast compensation.
Below the transmitance of the blue pixel of the display panel doped with D-π-A structure dye molecule and traditional Matrix-Vcom panel is compared.
According to an example of the present invention, under the consistent prerequisite of aperture opening ratio, by simulated experiment, obtain the transmitance doped with the blue pixel of the display panel of D-π-A structure dye molecule and traditional Matrix-Vcom panel; Wherein, after doping D-π-A structure dye molecule, the transmitance of blue pixel is 6.73, and the transmitance of the blue pixel of traditional Matrix-Vcom panel is 6.44, visible, after doping D-π-A structure dye molecule, the transmitance of blue pixel has promoted approximately 4.5%, thereby has realized colour cast compensation to a certain degree.
The present invention also provides a kind of display device, and it comprises display base plate as above.
In embodiments of the present invention, above-mentioned display device can be but be not limited to be the display device such as liquid crystal display, liquid crystal panel, LCD TV, OLED (organic light emitting diode) display.
The above, be only preferred embodiment of the present invention, is not intended to limit protection scope of the present invention.
