Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not paying creative work belongs to the scope that the present invention protects.
The embodiment of the invention provides a kind of crosstalk reduction method and double-vision display of double-vision display.
Embodiment 1:
As shown in Figure 3, the reduction method of crosstalking of the double-vision display that the embodiment of the invention provided comprises:
S1: obtain and desire the corresponding primary voltage of gray-scale displayed;
S2: the bucking voltage of obtaining primary voltage;
S3: primary voltage and bucking voltage are superposeed, obtain compensation back voltage;
S4: will compensate back voltage and be applied on the pixel electrode of sub-pixel.
Because the influence of crosstalk phenomenon; Primary voltage can produce deviation, and the effect of bucking voltage is exactly to compensate this a part of deviation, has reduced the influence of crosstalking to primary voltage; Also reduced the deviation of display gray scale on the sub-pixel; Improved display quality, so solved existing double-vision display because the crosstalk phenomenon between the adjacent subpixels causes the affected technical matters of display quality.
Further, in the embodiment of the invention, bucking voltage is two side bucking voltage sums; Two side bucking voltages are respectively applied for the crosstalking of interference voltage generation on compensation this pixel electrode left side and the right.Because in the double-vision display; The sub-pixel of left side vision area and right vision area is alternately; So except that the pixel electrode on both sides; What most pixel electrode received crosstalks from the right and left, so bucking voltage also is made up of two side bucking voltages, is respectively applied for compensation crosstalking from the right and left.
Further, in the embodiment of the invention, interference voltage is the primary voltage on the pixel electrode on this pixel electrode left side or the right.Interference voltage should be the actual voltage that applies, just primary voltage and a bucking voltage sum on the pixel electrode on this pixel electrode left side or the right.In fact, bucking voltage is much smaller than virtual voltage, thus in order to simplify calculating, ignore bucking voltage, and only the primary voltage of interference source as interference voltage.
Further, in the embodiment of the invention, the numerical value of side bucking voltage draws according to the interference voltage of primary voltage on this pixel electrode and a certain side of this pixel electrode.The numerical value of side bucking voltage depends on the departure that the interference voltage of this side causes primary voltage, and this departure is determined by two factors: the one, and the size of primary voltage itself, the 2nd, the size of the interference voltage of this side.The difference of these two voltages and proportionate relationship have determined the size of departure, so the numerical value of side bucking voltage also draws according to the size of these two voltages.
Further, in the embodiment of the invention, the numerical value of side bucking voltage draws according to the interference voltage of primary voltage on this pixel electrode and a certain side of this pixel electrode, is specially:
S11: first image that shows certain gray scale in the left vision area of double-vision display; Give on the pixel electrode of sub-pixel of left vision area and apply and the corresponding primary voltage Va of this gray scale; Show second image of another gray scale in right vision area, give on the pixel electrode of sub-pixel of right vision area to apply and the corresponding primary voltage Vb of this another gray scale;
S12: measure left vision area gray-scale displayed, regulate Va simultaneously, reach normal until the gray scale of left vision area;
S13: this moment, Va was adjusted to Va ', and then bucking voltage is Va '-Va=2Vab, and Vab is the side bucking voltage of primary voltage Va when the interference voltage of a side is Vb.
As primary voltage, Vb reaches normal gray scale as interference voltage when Va is adjusted to Va ', promptly compensated the influence of crosstalking with Va.The Va ' of this moment is the actual voltage that applies on the pixel electrode of left vision area, and just primary voltage and bucking voltage sum are so bucking voltage is Va '-Va.Because the interference voltage from the right and left that the pixel electrode of left vision area receives all is Vb, thus bucking voltage 1/2nd, promptly Vab is exactly the side bucking voltage of primary voltage Va when the interference voltage of a side is Vb.
Embodiment 2:
Present embodiment and embodiment 1 are basic identical, and its difference is: as shown in Figure 4, in the present embodiment, the numerical value of side bucking voltage draws according to the interference voltage of primary voltage on this pixel electrode and a certain side of this pixel electrode, is specially:
S21: first image that shows certain gray scale in the right vision area of double-vision display; Give on the pixel electrode of sub-pixel of right vision area and apply and the corresponding primary voltage Va of this gray scale; Show second image of another gray scale in left vision area, give on the pixel electrode of sub-pixel of left vision area to apply and the corresponding primary voltage Vb of this another gray scale;
S22: measure right vision area gray-scale displayed, regulate Va simultaneously, reach normal until the gray scale of right vision area;
S23: this moment, Va was adjusted to Va ', and then bucking voltage is Va '-Va=2Vab, and Vab is the side bucking voltage of primary voltage Va when the interference voltage of a side is Vb.
In the present embodiment, be equivalent to left vision area among the embodiment 1 and right vision area transposition.In practical operation, both can measure right vision area to left vision area as interference source, also can measure left vision area to right vision area as interference source, select easy mode as the case may be.
Embodiment 3:
Present embodiment and embodiment 1 are basic identical; Its difference is: in the present embodiment; The numerical value of side bucking voltage draws according to the interference voltage of primary voltage on this pixel electrode and a certain side of this pixel electrode; Be specially: the numerical value of side bucking voltage is chosen according to the interference voltage of primary voltage on this pixel electrode and a certain side of this pixel electrode from pre-prepd side null balance voltmeter.
Sub-pixel can show the how many kinds of gray scale, and just the exponent number of GTG is fixed, and to the value identical a plurality of not of the same race of primary voltage being arranged, normally 64 kinds or 256 kinds.Utilize the computing method of Vab among embodiment 1 and the embodiment 2, can calculate all n kind values of all n kind values of Va and Vb, the Vab of the n * n under all combined situation, and form the side null balance voltmeter, like following table.
If the primary voltage on two adjacent pixel electrodes equates, then can not crosstalk each other, so the side bucking voltage on the diagonal line (for example V11, V22) is zero in the side null balance voltmeter; Because two adjacent pixel electrodes are crosstalked each other, thus in the side null balance voltmeter about two side bucking voltages of diagonal line symmetry opposite number (for example V12=-V21) each other.Therefore, in fact calculative side bucking voltage is not n
2Individual, and compare n
2Half also to lack.
