Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
For transparent display, determine the transmittance that key parameter is this display device that whether good its transparent display effect is, specific to each pixel, how to guarantee that the transmittance of pixel cell has also just become the key that guarantees to realize good clear display effect.For traditional display device, the demonstration GTG value of pixel conventionally and transmittance have direct relation, especially for TFT display device, the demonstration GTG value of element is higher can drive liquid crystal deflecting element so that more light transmission, thereby the transmittance of pixel is also just higher.Therefore, in the transparent display driving method described in the embodiment of the present invention, can be by regulating the demonstration GTG value of pixel to adjust the transmittance of transparent display integral body.
Concrete, the transparent display driving method that the embodiment of the present invention provides, as shown in Figure 1, comprising:
S101, obtain the demonstration GTG value that shows subregion.
The demonstration GTG value of the demonstration subregion that S102, basis get obtains being positioned at this demonstration subregion the demonstration GTG value of the compensation subregion of same pixel region.
Concrete, on array base palte, can comprise a plurality of pixel regions, each pixel region can be divided into again at least one and show subregion and at least one compensation subregion, includes a plurality of pixel cells that matrix form is arranged that are in each shows subregion or compensates subregion.
In embodiments of the present invention, when showing that the demonstration GTG value of subregion changes, the transmittance of this demonstration subregion equally also can change, for the transmittance of pixel region integral body is compensated, can be by the transmittance that is positioned at the compensation subregion of same pixel region with this demonstration subregion is changed accordingly, to realize the balance of pixel region integral light-transmitting rate.
S103, the pixel cell output display signal according to the demonstration GTG value of compensation subregion to this compensation subregion, so that show that the transmittance of subregion and the transmittance sum of compensation subregion equal default transmittance.
Wherein, the transmittance that shows subregion is for showing the average transmittance and the product that shows subregion area of subregion; The average transmittance that the transmittance of compensation subregion is compensation subregion and the product of compensation subregion area.Due in the process of practical application, show that the area of subregion and the area that compensates subregion may be not identical, by the area in the average transmittance in each sub regions and this region comparatively transmittance situation of objective appraisal pixel region integral body that multiplies each other.Wherein average transmittance can be the transmittance in a certain less preset area, for example, can be the transmittance situation of a pixel cell.
Concrete, the transmittance of pixel region integral body equals to show the transmittance and the transmittance sum that compensates subregion of subregion, when the transmittance of pixel region integral body hour, because transmitted ray is very few, substantially do not see the background that is positioned at display device rear, be difficult to effectively realize transparent display effect.Therefore can be according to the value of the selected default transmittance of actual conditions, for example, for existing display device, default transmittance can be for being more than or equal to a determined value of 6%, and this is because could effectively see the background that is positioned at display device rear clearly when the transmittance of pixel region integral body is greater than 6%.
The transparent display driving method that the embodiment of the present invention provides, by obtaining the demonstration GTG value that shows subregion in pixel region, and according to this demonstration GTG value, obtain being positioned at equally the demonstration GTG value of the compensation subregion of this pixel region, regulate the demonstration GTG of compensation subregion pixel cell, so that show that the transmittance of subregion and the transmittance sum of compensation subregion equal default transmittance.So, by detecting inputting the image of each pixel region, in pixel region, outside the corresponding subregion pixel cell showing, form the transmittance that complementary retrieved image usually compensates this pixel region integral body, make when showing any picture, the transmittance of each pixel region remains unchanged substantially, avoided the variation of pixel transmittance, thereby make all can well observe the object that is positioned at display device rear when showing any picture, realize good transparent display effect.
For by detecting inputting the image of each pixel region, in pixel region, outside the corresponding subregion pixel cell showing, form transmittance that complementary retrieved image usually compensates this pixel region integral body to realize good transparent display effect, in embodiments of the present invention, compensation subregion can comprise at least one white pixel unit; Or compensation subregion can also comprise at least one white display element, and this white display element is carried out white displays by rgb pixels unit.
Take and there is RGB(RGB) three color pixel cellular array substrates are example, the array base-plate structure that comprises white display element can be as shown in Figure 2, wherein, each pixel region 20 comprises that 22 of subregions of compensation comprise a white sub-pixels 221 of extra setting by a red sub-pixel 211, green sub-pixels 212 and the demonstration subregion 21 that blue subpixels 213 forms.In array base palte as shown in Figure 2, the area of white sub-pixels 221 is identical with the sub-pixel area of its excess-three kind color, and this only illustrates certainly, and the present invention does not limit this.RGBW(red, green, blue and white like this) array base palte for structure, by the total light transmittance of RGB area image is detected, compensates adjusting to the transmittance of white sub-pixels and can realize good transparent display effect.
In the array base palte of RGBW structure, white sub-pixels cannot be carried out the demonstration of image, and the white sub-pixels of compensation subregion can also be carried out white displays by least one rgb pixels unit.As shown in Figure 3, each pixel region 30 comprises two groups of spaced RGB sub-pixels, without carry out transmittance compensation in the situation that, two groups of RGB sub-pixels all can normally show as display pixel, when the total light transmittance of pixel region is lower, one group of RGB sub-pixel region can be used as and shows subregion 31, and another group RGB sub-pixel now carries out white light demonstration, and subregion 32 by way of compensation.
Can see, in array base palte as shown in Figure 3, pixel cell by way of compensation can be used as display pixel equally, but owing to showing that the area of subregion equals to compensate subregion, like this when carrying out transmittance compensation, because display pixel area has nearly reduced half, therefore the resolution of display frame will be reduced greatly.Further, in embodiments of the present invention, the area of compensation subregion can be less than the area that shows subregion.Concrete, as shown in Figure 4, each pixel region 40 comprises one group of large RGB sub-pixel and one group little RGB sub-pixel, two groups of RGB sub-pixels are spaced up and down, and without carry out transmittance compensation in the situation that, two groups of RGB sub-pixels all can normally show as display pixel, when the total light transmittance of pixel region is lower, large RGB sub-pixel region can be used as and shows subregion 41, and little RGB sub-pixel now carries out white light demonstration, and subregion 42 by way of compensation.So, can when effectively realizing transparent display effect, guarantee the resolution of display frame, further improve the display effect of display device.
It should be noted that, in array base palte as above, the arrangement mode of sub-pixel also only illustrates, and the embodiment of the present invention is not restricted this.
Concrete, below to take the array base-plate structure with big or small pixel shown in Fig. 4 be example, and the transparent display driving method that the embodiment of the present invention is provided is elaborated.
Wherein, suppose to show that the demonstration GTG value of large pixel in subregion 41 is m, average transmittance corresponding to this demonstration GTG value is Ym, and this average transmittance Ym is difficult to realize effective transparent display effect.For the integral light-transmitting rate to pixel region 40 compensates, need to be to compensation the average transmittance Yn of the small pixel in subregion 42 adjust, the concrete demonstration GTG value n that can compensate small pixel in subregion 42 by adjustment adjusts.
The area that shows subregion 41 is a, and the area of compensation subregion 42 is b, in order to make to show that the transmittance of subregion and the transmittance sum of compensation subregion equal default transmittance, have relation accordingly:
A*Ym+b*Yn=K, wherein K is constant,
Make Yn=(K-a*Ym)/b, by the average transmittance of large pixel and the area of two sub regions, can obtain the average transmittance of small pixel.
Because GTG value is conventionally between 0～255, wherein the demonstration GTG value of small pixel is n, and this demonstration GTG value n with the relation of corresponding average transmittance Yn can be:
Yn=(n／255)^x，
Same, large pixel shows GTG m, and this demonstration GTG value m with the relation of corresponding average transmittance Ym can be:
Ym=(m／255)^z，
Wherein x and z are according to the selected constant of actual conditions.As choose x=2.0, z=2.2, can calculate:
Yn=(K-a*Ym)/b, will, with co-relation substitution, can obtain:
(n／255)^2.0=（K-a*(m／255)^2.2）/b
n／255=(（K-a*(m／255)^2.2）/b)^(1/2)
n=255*（(（K-a*(m／255)^2.2）/b)^(1/2)）。
The demonstration GTG value n that so, can obtain small pixel according to area a, the b of the demonstration GTG value m of large pixel, two sub regions and default transmittance K.
The demonstration GTG value n of this small pixel can be predefined analog voltage, to realize the complementation of big or small pixel transmittance, or the demonstration GTG value n of this small pixel also can adopt input data are judged, according to large pixel gray level, the GTG that calculates small pixel shows, carry out big or small pixel demonstration, realize when the large pixel display frame of RGB GTG is higher, small pixel shows lower picture GTG, otherwise when the large pixel display frame of RGB GTG is lower, small pixel shows higher picture GTG.Concrete, can show that the demonstration GTG value of subregion and the relation of transmittance can be as shown in curve A as shown in Figure 5, the compensation demonstration GTG value of subregion and the relation of transmittance can be as shown in curve B.
Further, the transparent display driving method that the embodiment of the present invention provides can as shown in Figure 6, comprise:
S601, obtain the demonstration GTG value that shows subregion.
The demonstration GTG value of the demonstration subregion that S602, basis get obtains the transmittance of this demonstration subregion.
For example, can search mapping table according to the demonstration GTG value of the demonstration subregion getting, obtain the transmittance of this demonstration subregion.Wherein, mapping table can comprise various transmittance and different demonstration GTG values, and each transmittance is all corresponding with a unique demonstration GTG value.
S603, according to showing the transmittance of subregion and the transmittance that default transmittance obtains being positioned at this demonstrations subregion the compensation subregion of same pixel region, show that the transmittance of subregion and the transmittance sum of compensation subregion equal to preset transmittance.
S604, according to the transmittance of compensation subregion, obtain the demonstration GTG value of this compensation subregion.
For example, can search mapping table according to the transmittance of compensation subregion equally, obtain the demonstration GTG value of this compensation subregion.
S605, the pixel cell output display signal according to the demonstration GTG value of compensation subregion to this compensation subregion, so that show that the transmittance of subregion and the transmittance sum of compensation subregion equal default transmittance.
Wherein, the transmittance that shows subregion is for showing the average transmittance and the product that shows subregion area of subregion; The average transmittance that the transmittance of compensation subregion is compensation subregion and the product of compensation subregion area.
Concrete, in showing subregion, the demonstration GTG value of RGB sub-pixel input is respectively R=100, G=120, B=200, according to corresponding Gamma formula, calculate, or show that according to searching GTG value and the mapping table between transmittance draw respectively the transmittance Tr(R100 of corresponding R)=1%, the transmittance Tr(G120 of G)=3%, the transmittance Tr(B200 of B)=1.4%, therefore show that the average transmittance of subregion is TrA=(Tr(R100)+Tr(G120)+Tr(B200))/3=1.8%, suppose that default transmittance is 10%, show that subregion and the area hypothesis of compensation subregion are 1, according to this, can calculate again the transmitance Trw=10%-1.8%=8.2% corresponding to RGB of W sub-pixel, so just W pixel can be realized to 8.2% transmittance, according to corresponding Gamma formula, calculate again, or show that according to searching the mapping table showing between GTG value and transmittance the demonstration GTG value of W sub-pixel shows.
Wherein, show mapping table between GTG value and transmittance can shape as following table 1:
| trw transmittance | show GTG |
| trw0 | 0 |
| trw1 | 1 |
| .。。 | 。。。 |
| Trw255 | 255 |
Table 1
The corresponding transmittance of 0 to 255 GTG of correspondence is all made to table to be stored in chip processor, by Trw being searched to the corresponding GTG that shows nearby, such as Trw=8.2%, through finding between Trw200=8.1%, between Trw201=8.25%, just can search corresponding demonstration GTG is nearby 201.
Or, show that the corresponding relation between GTG value and transmittance can also be tried to achieve mutually by Gamma formula.Show that the corresponding transmittance of GTG value n is:
Trwn=Trw255*(n／255)^r
Wherein Trw255 and r are known number, and corresponding, the corresponding demonstration GTG of transmittance Trwn value n is:
n=255*(Trwn/Trw255)^(1/r)
Certainly, with the constant in above formula, can choose according to actual conditions, also only illustrate above, and the restriction of not the present invention being done.
