Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
For transparent display, determine that a whether respond well key parameter of its Transparence Display is this display
How the light transmittance of device, for each pixel, ensure that the light transmittance of pixel cell has also just become to guarantee reality
The key of existing good clear display effect.For traditional display device, the display grey decision-making of pixel is generally and light transmittance
Have direct relation, especially for TFT display device, the display grey decision-making of element is higher can drive liquid crystal molecule deflection with
So that more light transmissions, thus the light transmittance of pixel is also higher.Therefore, the Transparence Display described in the embodiment of the present invention
In apparatus driving circuit, the overall light transmittance of transparent display can be adjusted by adjusting the display grey decision-making of pixel.
Specifically, transparent display driving method provided in an embodiment of the present invention, as shown in figure 1, include：
S101, the display grey decision-making of acquisition display subregion.
The display GTG of the display subregion that S102, basis get is worth to be located at same pixel with this display subregion
The display grey decision-making of the compensation subregion in region.
Specifically, array base palte can include multiple pixel regions, each pixel region can be divided at least one again
Display subregion and at least one compensate subregion, each display subregion or compensate subregion in all include multiple in square
The pixel cell of formation formula arrangement.
In embodiments of the present invention, when showing the display GTG value changes of subregion, the light transmittance of this display subregion
Equally also can change, in order to the light transmittance overall to pixel region compensates, can by this display subregion
The light transmittance of the compensation subregion in same pixel region is changed, accordingly to realize pixel region integral light-transmitting rate
Balance.
S103, the display pixel cell output display signal to this compensation subregion for the grey decision-making according to compensation subregion,
So that the light transmittance of display subregion is equal to default light transmittance with the light transmittance sum compensating subregion.
Wherein, the light transmittance of display subregion is the average transmittance of display subregion and taking advantage of of display subregion area
Long-pending；The light transmittance compensating subregion is to compensate the average transmittance of subregion and the product compensating subregion area.Due in reality
During the application of border, the area of display subregion and the area compensating subregion may and differ, by each sub-regions
Average transmittance be multiplied with the area in this region can the more overall light transmittance situation of objective appraisal pixel region.Wherein
Average transmittance can be the light transmittance in a certain less preset area, for example, can be the light transmittance feelings of a pixel cell
Condition.
Specifically, the overall light transmittance of pixel region is equal to the light transmittance of display subregion and the light transmittance compensating subregion
Sum, when the overall light transmittance of pixel region is less, because transmitted ray is very few, does not substantially see after display device
The background of side is it is difficult to be effectively realized Transparence Display effect.The value of default light transmittance, example therefore can be selected according to practical situation
As, for existing display device, default light transmittance can be a determination value more than or equal to 6%, this is because in picture
The light transmittance of plain region entirety could effectively see the background positioned at display device rear clearly when being more than 6%.
Transparent display driving method provided in an embodiment of the present invention, shows subregion by obtaining in pixel region
Display grey decision-making, and it is worth to the display GTG compensating subregion being similarly positioned in this pixel region according to this display GTG
Value, adjusts the display GTG compensating subregion pixel cell, so that showing the light transmittance of subregion and the saturating of compensation subregion
Light rate sum is equal to default light transmittance.So, by detecting to the image inputting each pixel region, in pixel
The retrieved image forming complementation outside the subregion pixel cell of corresponding display in region usually compensates the saturating of this pixel region entirety
Light rate is so that when showing any picture, the light transmittance of each pixel region is held essentially constant, it is to avoid pixel transmittance rate
Change so that object positioned at display device rear all can be observed well when showing any picture, realize good
Good Transparence Display effect.
In order to by detecting to the image inputting each pixel region, correspond to the sub-district of display in pixel region
Forming the retrieved image of complementation outside the pixel cell of domain, usually to compensate the overall light transmittance of this pixel region good transparent to realize
Display effect, in embodiments of the present invention, compensates subregion and can include at least one white pixel unit；Or compensation sub-district
Domain can also include at least one white display element, and this white display element carries out white displays by rgb pixels unit.
To have RGB（RGB）As a example three-color pixel cellular array substrate, including the array base of white display element
Hardened structure can as shown in Fig. 2 wherein, and each pixel region 20 is included by 211, sub- picture of green of a red sub-pixel
Element 212 and the display subregion 21 of blue subpixels 213 composition, compensate that subregion 22 then includes additionally arranging
White sub-pixels 221.In array base palte as shown in Figure 2, the sub- picture of the area of white sub-pixels 221 and its excess-three kind color
Vegetarian noodles amasss identical, and this is merely illustrative certainly, and the present invention is not limited to this.Such a RGBW（Red, green, blue and white）Knot
The array base palte of structure, by detecting to the total light transmittance of RGB area image, compensates to the light transmittance of white sub-pixels
Adjust and can realize good Transparence Display effect.
In the array base palte of RGBW structure, white sub-pixels cannot be carried out the display of image, compensates the white of subregion
Sub-pixel can also carry out white displays by least one rgb pixels unit.As shown in figure 3, each pixel region 30
Including two groups of spaced RGB sub-pixels, in the case of need not carrying out light transmittance compensation, two groups of RGB sub-pixels all can
Normally show as display pixel, when the total light transmittance of pixel region is relatively low, one group of RGB sub-pixel region can conduct
Display subregion 31, another group of RGB sub-pixel now carries out white light and shows, as compensation subregion 32.
Can see, in array base palte as shown in Figure 3, can also serve as showing picture as the pixel cell compensating
Element, but compensate subregion due to showing that the area of subregion is equal to, so when carrying out light transmittance compensation, due to display pixel face
Amass and decrease nearly half, therefore will substantially reduce the resolution of display picture.Further, in embodiments of the present invention, mend
The area repaying subregion can be less than the area of display subregion.Specifically, as shown in figure 4, each pixel region 40 includes
One group of big RGB sub-pixel and one group little RGB sub-pixel, two groups of RGB sub-pixels are spaced up and down, need not carry out light transmittance benefit
In the case of repaying, two groups of RGB sub-pixels all normally can show as display pixel, when the total light transmittance of pixel region is relatively low
When, big RGB sub-pixel region can now carry out white light and show, as benefit as display subregion 41, little RGB sub-pixel
Repay subregion 42.So, the resolution of display picture can be guaranteed while effectively realizing Transparence Display effect, enter one
Step improves the display effect of display device.
It should be noted that in array base palte as above, the arrangement mode of sub-pixel is also merely illustrative,
The embodiment of the present invention is not restricted to this.
Specifically, shown in below by Fig. 4 there is the array base-plate structure of size pixel as a example, the embodiment of the present invention is carried
For transparent display driving method be described in detail.
Where it is assumed that the display grey decision-making of big pixel is m in display subregion 41, this display grey decision-making is corresponding averagely saturating
Light rate is Ym, and this average transmittance Ym is difficult to effective Transparence Display effect.For the integral light-transmitting to pixel region 40
Rate compensates, and needs the average transmittance Yn of the small pixel compensating in subregion 42 is adjusted, specifically can pass through
The display grey decision-making n that adjustment compensates small pixel in subregion 42 is adjusted.
The area of display subregion 41 is a, and the area compensating subregion 42 is b, in order that the light transmittance of display subregion
It is equal to default light transmittance with the light transmittance sum compensating subregion, there is relation accordingly：
A*Ym+b*Yn=K, wherein K are constant,
Make Yn=（K-a*Ym）/ b, can be obtained by the area of the average transmittance of big pixel and two sub-regions
Average transmittance to small pixel.
Because grey decision-making is generally between 0～255, wherein small pixel display grey decision-making be n, this display grey decision-making n with
The relation of corresponding average transmittance Yn can be：
Yn=(n/255) ^x,
Likewise, big pixel shows that GTG m, this display grey decision-making m with the relation of corresponding average transmittance Ym can be：
Ym=(m/255) ^z,
Wherein x and z is the constant according to selected by practical situation.As chosen x=2.0, z=2.2, then can calculate：
Yn=（K-a*Ym）/ b, relation above is substituted into, and can get：
(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)）.
So, according to the display grey decision-making m of big pixel, area a, b of two sub-regions and default light transmittance K it is
The display grey decision-making n of small pixel can be obtained.
The display grey decision-making n of this small pixel can be analog voltage set in advance, to realize size pixel light transmittance
Complementation, or the display grey decision-making n of this small pixel can also be using judging to input data, according to big pixel gray level, meter
The GTG calculating small pixel shows, carries out size pixel and shows, realizes when RGB big pixel display picture GTG is higher, little
Pixel shows the relatively low picture GTG of ratio, on the contrary when RGB big pixel display picture GTG than relatively low when, small pixel shows higher picture
Face GTG.Specifically, can be as shown in figure 5, the display grey decision-making of display subregion and the relation of light transmittance can be as curve A institutes
Show, the relation of the display grey decision-making and light transmittance that compensate subregion can be as curveb.
Further, transparent display driving method provided in an embodiment of the present invention can be as shown in fig. 6, include：
S601, the display grey decision-making of acquisition display subregion.
The display GTG of the display subregion that S602, basis get is worth to the light transmittance of this display subregion.
For example, it is possible to mapping table is searched according to the display grey decision-making of the display subregion getting, obtain this display
The light transmittance of subregion.Wherein, mapping table can include various different light transmittances and different display grey decision-making, often
One light transmittance is all corresponding with unique one display grey decision-making.
S603, the light transmittance according to display subregion and default light transmittance obtain being located at same pixel with this display subregion
The light transmittance of the compensation subregion in region, the light transmittance of display subregion and the light transmittance sum compensating subregion are equal to default
Light transmittance.
S604, the display grey decision-making of this compensation subregion is obtained according to the light transmittance compensating subregion.
For example, equally mapping table can be searched according to the light transmittance compensating subregion, obtain this compensation subregion
Display grey decision-making.
S605, the display pixel cell output display signal to this compensation subregion for the grey decision-making according to compensation subregion,
So that the light transmittance of display subregion is equal to default light transmittance with the light transmittance sum compensating subregion.
Wherein, the light transmittance of display subregion is the average transmittance of display subregion and taking advantage of of display subregion area
Long-pending；The light transmittance compensating subregion is to compensate the average transmittance of subregion and the product compensating subregion area.
Specifically, in display subregion, the display grey decision-making of RGB sub-pixel input is respectively R=100, G=120, B=
200, calculated according to corresponding Gamma formula, or according to the corresponding relation searched between display grey decision-making and light transmittance
Table draws the light transmittance Tr of corresponding R respectively（R100）The light transmittance Tr of=1%, G（G120）The light transmittance Tr of=3%, B（B200）=
1.4%, therefore show that the average transmittance of subregion is TrA=（Tr（R100）+Tr（G120）+Tr（B200））/ 3=1.8% it is assumed that
Default light transmittance is 10%, and display subregion is assumed to be 1 with the area compensating subregion, can calculate W further according to this
W pixel thus can be realized 8.2% light transmittance by corresponding transmitance Trw=10%-1.8%=8.2% of RGB of pixel, then root
Calculated according to corresponding Gamma formula, or drawn W according to searching the mapping table between display grey decision-making and light transmittance
The display grey decision-making of sub-pixel is shown.
Wherein, the mapping table between display grey decision-making and light transmittance can be with shape such as table 1 below：
| Trw light transmittance | Display GTG |
| Trw0 | 0 |
| Trw1 | 1 |
| ... | ... |
| Trw255 | 255 |
Table 1
The corresponding light transmittance of corresponding 0 to 255 GTGs is all made table be stored in chip processor, by carrying out Trw
Search corresponding display GTG nearby, such as Trw=8.2%, through finding between Trw200=8.1%, Trw201=8.25%, just
It is 201 that corresponding display GTG can be searched nearby.
Or, the corresponding relation between display grey decision-making and light transmittance mutually can also be tried to achieve by Gamma formula.Display
Light transmittance corresponding to grey decision-making n is：
Trwn=Trw255* (n/255) ^r
Wherein Trw255 and r is datum, and accordingly, the display grey decision-making n corresponding to light transmittance Trwn is：
n=255*(Trwn/Trw255)^(1/r)
Certainly, the constant in above formula can be chosen according to practical situation, above is also merely illustrative, and simultaneously
The non-restriction that the present invention is done.
The such a transparent display driving method being provided using the embodiment of the present invention, by input each
The image of pixel region is detected, and forms the compensation of complementation outside the subregion pixel cell of corresponding display in pixel region

Wherein, the light transmittance of display subregion is the average transmittance of display subregion and taking advantage of of display subregion area
Long-pending；The light transmittance compensating subregion is to compensate the average transmittance of subregion and the product compensating subregion area.Due in reality
During the application of border, the area of display subregion and the area compensating subregion may and differ, by each sub-regions
Average transmittance be multiplied with the area in this region can the more overall light transmittance situation of objective appraisal pixel region.Wherein
Average transmittance can be the light transmittance in a certain less preset area, for example, can be the light transmittance feelings of a pixel cell
Condition.
Specifically, the overall light transmittance of pixel region is equal to the light transmittance of display subregion and the light transmittance compensating subregion
Sum, when the overall light transmittance of pixel region is less, because transmitted ray is very few, does not substantially see after display device
