Luminance difference.Luminance difference be present between perceiving the region maximum less than script luminance difference due to user, then user also just feels
Know less than luminance difference be present between other regions, so as to avoid influenceing the viewing effect of user and avoid reducing user
Viewing experience.
Wherein, in an embodiment of the invention, when the GTG after with increase is in display content on liquid crystal panel, detection
Whether liquid crystal panel also has light leakage phenomena, can by it is following 11)~13) flow realize：
11), when the GTG after with increase is in display content on liquid crystal panel, the regional on liquid crystal panel is obtained
Display brightness；
In embodiments of the present invention, as shown in Fig. 2 technical staff in advance can be in the front of the liquid crystal panel of terminal 01
Image capture device 02 is set, and image capture device 02 is directed at liquid crystal panel, and by terminal 01 and image capture device
02 communication connection.In this way, terminal 01 can control the image of the regional on the shooting liquid crystal panel of image capture device 02, and
The image of shooting is back to terminal 01, terminal 01 receives the image that image capture device 02 is sent.
Wherein it is possible to according to the model split of similar nine grids it is 9 regions or 16 regions etc. by liquid crystal panel.
For any one region on liquid crystal panel, the figure in the region that image capture device is sent is received in terminal
As after, red component, green component and the blue component of each pixel in the image can be obtained.
Then for any one pixel in the image, red component, green component that can be according to the pixel
And blue component obtains the display brightness of the pixel.It is same to perform for other each pixels in the image
Operation is stated, the display brightness of each pixel in the image can be so obtained, afterwards, the picture in the image can be calculated
The average value of the display brightness of vegetarian refreshments, and as the display brightness in the region.
For other each regions on liquid crystal panel, aforesaid operations are equally performed, can so obtain liquid crystal panel
On regional display brightness.
Wherein, the display brightness of pixel is obtained in the red component according to pixel, green component and blue component
When, pixel can be calculated according to equation below according to the red component, green component and blue component of pixel
Display brightness：
L=O*R+P*G+Q*B；
Wherein, in above-mentioned formula, L is the display brightness of pixel, and O, P and Q are respectively default weight coefficient, and R is red
Colouring component, G is green component and B is blue component.
For example, it can be that 0.587 and Q can be 0.114 etc. that P, which can be 0.229, P,.
12) luminance difference between the display brightness in each two region, is obtained；
In embodiments of the present invention, for any one region on liquid crystal panel, calculate the region respectively with liquid crystal surface
The luminance difference between each region of other in addition to the region on plate.For other each areas on liquid crystal panel
Domain, equally perform aforesaid operations.In this way, the luminance difference between the display brightness in each two region can be obtained.
13), in multiple luminance differences, if there is the luminance difference more than preset difference value threshold value, liquid crystal panel is determined
Light leakage phenomena be present.
In embodiments of the present invention, if liquid crystal panel is not present light leakage phenomena, the regional on liquid crystal panel it
Between luminance difference it is all smaller, for example, the luminance difference between regional on liquid crystal panel is respectively less than preset difference value threshold value,
The luminance difference between regional even on liquid crystal panel is all 0.For a user, when user see liquid crystal plate face it
Afterwards, it will not feel that some regions on liquid crystal panel are brighter, some regions are dark, but feel all areas on liquid crystal panel
Brightness it is almost identical, and then do not interfere with the viewing effect of user and the viewing experience of user will not be reduced.
However, in multiple luminance differences, once at least one luminance difference be present is more than preset difference value threshold value, then illustrate
The light transmittance that at least one region on liquid crystal panel be present is more than the light transmittance in other regions, in this way, for a user, when with
After liquid crystal plate face is seen at family, it will feel that some regions on liquid crystal panel are brighter, some regions are dark, influence the sight of user
See effect and reduce the viewing experience of user, so as to light leakage phenomena occur.
Wherein, in an alternative embodiment of the invention, increase display content when GTG, can by it is following 21)~24)
Flow is realized：
21), in the luminance difference more than preset difference value threshold value, a luminance difference is selected；
22), in the corresponding relation between the luminance difference and GTG increment pre-set, the luminance difference with selection is searched
It is worth corresponding GTG increment；
If the luminance difference between certain two region on liquid crystal panel is larger, illustrate the light leakage phenomena of liquid crystal panel
The order of severity it is higher, that is, the light transmittance in a region on liquid crystal panel is much larger than the light transmittance in another region, human eye
The luminance difference between the two regions can be experienced easily.Exist in order that obtaining between human eye is not felt by the two regions
Luminance difference, that is, in order to eliminate light leakage phenomena, it is necessary to GTG when rolling up display content.Therefore, pre-setting
In corresponding relation between luminance difference and GTG increment, luminance difference is bigger, then corresponding GTG increment is bigger.
If the luminance difference between certain two region on liquid crystal panel is smaller, illustrate the light leakage phenomena of liquid crystal panel
The order of severity it is relatively low, that is, the light transmittance in a region on liquid crystal panel is just slightly larger than the printing opacity in another region
Slight luminance difference be present between the two regions can be experienced in rate, human eye.In order that obtaining human eye is not felt by the two
Luminance difference between region be present, that is, in order to eliminate light leakage phenomena, need to only increase GTG during display content on a small quantity.Therefore,
In corresponding relation between the luminance difference and GTG increment pre-set, luminance difference is smaller, then corresponding GTG increment
It is smaller.
So luminance difference is bigger, then need increased GTG increment bigger in display content on liquid crystal panel, it is bright
It is smaller to spend difference, then increased GTG increment is needed in display content on liquid crystal panel with regard to smaller.
Wherein, technical staff can set the corresponding relation between luminance difference and GTG increment in advance, in luminance difference
In corresponding relation between GTG increment, GTG increment is larger corresponding to larger luminance difference, less luminance difference pair
The GTG increment answered is smaller.Corresponding relation between luminance difference and GTG increment can be stored in local, can also be stored in
High in the clouds.
In this way, in this step, can be searched in the corresponding relation between the luminance difference and GTG increment pre-set
The GTG increment corresponding with the luminance difference of selection.
23), the GTG after being increased will be added with GTG and GTG increment；
24), with the GTG after increase on liquid crystal panel display content.
In embodiments of the present invention, in the luminance difference between the display brightness in each two region, if there is multiple
More than the luminance difference of preset difference value threshold value, and in the luminance difference more than preset difference value threshold value, larger luminance difference with
Gap between relatively low luminance difference is also larger.Meanwhile if it is in the brightness more than preset difference value threshold value in step 21)
Relatively low luminance difference is have selected in difference, then in step 22), because the luminance difference of selection is relatively low, is then found correspondingly
Voltage increment it is relatively low, although then causing the GTG after the increase that is obtained in step 23) more than original GTG, still
It is the GTG in a reduced levels.
Afterwards in the GTG after with increase after liquid crystal panel display content, the higher region of the luminance difference of script
In, may can also there is the problem of luminance difference is more than preset difference value threshold value, that is, after user sees liquid crystal panel, can also
Feel obvious luminance difference, and then influence the viewing effect of user and reduce the viewing experience of user.That is, it can also deposit
In light leakage phenomena.
Therefore, in order to avoid the GTG after with increase is after liquid crystal panel display content, also there is light leakage phenomena,
, can be big when a luminance difference is selected in the luminance difference more than preset difference value threshold value in another embodiment of the present invention
The luminance difference of maximum is selected in the luminance difference of preset difference value threshold value.
So in step 22), because the luminance difference of selection is maximum luminance difference, then corresponding GTG is found
Increment is also the maximum GTG increment in GTG increment corresponding to multiple luminance differences difference, and then is caused in step 23)
In GTG after obtained increase be more than original GTG, and the GTG after increasing can cause the maximum region of luminance difference it
Between luminance difference be less than preset difference value threshold value, even 0 so that user perceives has luminance difference less than between these regions
It is different.Luminance difference be present between perceiving the region maximum less than script luminance difference due to user, then user also just perceive less than
Luminance difference be present between other regions, so as to avoid influenceing the viewing effect of user and avoid reducing the viewing of user
Experience.
In step S105, with the target gray scale determined on liquid crystal panel display target content.
Wherein it is possible to according to the corresponding relation between the GTG and voltage pre-set, it is determined that with the target ash determined
The corresponding voltage of rank；Then the target gray scale with determining is applied to liquid crystal panel in display target content on liquid crystal panel
Corresponding voltage.
The embodiment of the present invention is to adjust the voltage applied to liquid crystal panel to adjust the GTG for display content.Technology
Personnel can set the corresponding relation between GTG and voltage in advance, different in the corresponding relation between GTG and voltage
Voltage corresponding to GTG is different.Corresponding relation between GTG and voltage can be stored in local, can also store beyond the clouds.
Therefore, if it is desirable to show a certain content on liquid crystal panel with a certain GTG, then obtaining being used to show that this is interior
After the GTG of appearance, it can be searched corresponding with the GTG in the corresponding relation between the GTG and voltage pre-set
Voltage, and apply the voltage that finds to liquid crystal panel when showing the content on liquid crystal panel, such can realize with
The GTG shows the content on liquid crystal panel.
In embodiments of the present invention, when applying different voltages to liquid crystal panel, the rotation of the liquid crystal molecule on liquid crystal panel
Gyration is different.In the anglec of rotation difference of the liquid crystal molecule on liquid crystal panel, the light transmittance of liquid crystal panel is different, and then liquid
The brightness for the content that crystal panel is shown is different, that is, GTG is different.
Therefore, if applying the target gray scale phase with determining to liquid crystal panel in display target content on liquid crystal panel
Corresponding voltage, then liquid crystal panel will be with target gray scale display target content.
In embodiments of the present invention, due to the light leakage phenomena of liquid crystal panel be often as the self gravitation of liquid crystal panel with
And the effect of module screen structural stress and caused by, and generally can not by repairing hardware and liquid crystal panel not light leak, and then
Avoid influenceing the viewing effect of user and avoid reducing the viewing experience of user.
In embodiments of the present invention, terminal with low GTG on liquid crystal panel after display content, if liquid crystal panel leaks
Light, because light can pass through the region of the light leak on liquid crystal panel, without by other regions on liquid crystal panel, that is, its
His region is light tight, and therefore, the region of light leak is brighter, and other regions are dark, and now user is easily with regard to that can experience liquid crystal
The luminance difference of different zones on panel, and then the viewing effect of user is influenceed, and the viewing experience of user is reduced, occur
Light leakage phenomena.
And terminal with high gray on liquid crystal panel after display content, even if liquid crystal panel light leak, but light not only can be saturating
The region for the light leak crossed on liquid crystal panel, other regions on liquid crystal panel can be also passed through, through the light leak on liquid crystal panel
The light in region be not only due to liquid crystal panel self gravitation and module screen structural stress effect and caused by, due also to liquid
Caused by liquid crystal molecule skew in crystal panel, simultaneously because light through the light-leaking area on liquid crystal panel and through liquid crystal surface
The just same light source in other regions of plate, therefore, the region of the light leak on liquid crystal panel is brighter, and other regions are also brighter,
That is, the luminance difference between the region of the light leak on liquid crystal panel and other regions is very low, or even indifference.In this way, even if by
Cause liquid crystal panel light leak in self gravitation and module screen the structural stress effect of liquid crystal panel, but user will not also feel
Luminance difference be present by the different zones on liquid crystal panel, do not interfere with the viewing effect of user and will not reduce user's
Viewing experience, and then light leakage phenomena is not present.
