2.1u, region 3 RC value be 2.0u, the RC value in region 4 is 1.9u, the RC value in region 5 is 1.8u and the RC value in region 6 is
1.7u。
In obtaining N number of region respectively after the corresponding RC value in each region, so that it may execute following S103:
S103, according to the corresponding RC value in each region, the corresponding VGH voltage in each region is adjusted, to adjust each region
Brightness.
After being got respectively by above-mentioned S102 and obtaining the corresponding RC value in each region in N number of region, so that it may root
According to the corresponding RC value in each region, the corresponding VGH voltage in each region is adjusted, exemplary, shown in Figure 3, Fig. 3 is this hair
A kind of schematic diagram for adjusting the corresponding VGH voltage in each region that bright embodiment provides, in conjunction with Fig. 3 as can be seen that can pass through
PMIC controls adjustable resistor and adjusts the corresponding VGH voltage in each region, thus realize the adjustment to each regional luminance, so that
The brightness in each region is consistent after adjustment, i.e., the difference between each regional luminance is less than preset value, is guaranteeing to show to realize
Under conditions of showing device image quality homogeneity, the flexibility of image quality adjustment is improved, and reduces the production cost and mould group of display
Cost.Wherein, preset value can be configured according to actual needs, here, specially how many for preset value, the present invention is implemented
Example, which is not done, further to be limited.
The adjusting method of panel luminance provided in an embodiment of the present invention, when adjusting panel luminance, in adjustment panel luminance
When, panel to be adjusted is first divided into N number of region, wherein N is the integer more than or equal to 2；And it obtains each in N number of region
The corresponding RC value in region；Further according to the corresponding RC value in each region, the corresponding VGH voltage in each region is adjusted, it is each to adjust
The brightness in region.It can be seen that the adjusting method of panel luminance provided in an embodiment of the present invention, in adjusting panel brightness, nothing
The adjusted value of display image quality need to be needed to obtain by the equipment except the panel that is additionally arranged as the prior art, but
Directly according to the corresponding RC value in each region, the corresponding VGH voltage in each region is adjusted, to adjust the brightness in each region, from
And realize under conditions of guaranteeing display image quality homogeneity, the flexibility of image quality adjustment is improved, and reduce display
Production cost and mould group cost.
Based on embodiment shown in FIG. 1, in order to more clearly in above-mentioned S103, how according to the corresponding RC in each region
Value, adjusts the corresponding VGH voltage in each region, exemplary to adjust the brightness in each region, shown in Figure 4, Fig. 4 is
The embodiment of the invention provides a kind of method schematic diagrams of brightness that each region is adjusted according to the corresponding RC value in each region, make
It obtains when adjusting the brightness in each region according to the corresponding RC value in each region, this method may include:
S401, according to the corresponding RC value in each region, determine target RC value.
Optionally, in embodiments of the present invention, when determining target RC value, can according to the corresponding RC value in each region,
The smallest RC value is determined as target RC value.Specifically, the corresponding RC value in each region in the N number of region that can be will acquire
It is compared, finds out the smallest RC value, which is target RC value.
It is exemplary, in combination with shown in Fig. 2, the RC value in the region 1 respectively obtained is 2.2u, the RC value in region 2 be 2.1u,
After the RC value in region 3 is 2.0u, the RC value in region 4 is 1.9u, the RC value in region 5 is 1.8u and the RC value in region 6 is 1.7u,
The corresponding RC value in each region can be compared, may thereby determine that the RC value in region 6 is the smallest RC value, i.e. region 6
Minimum RC value 1.7u is target RC value.

S402, difference between the corresponding RC value in first area and target RC value is determined.
Wherein, first area is any region in N number of region.
S403, according to the difference between the corresponding RC value in first area and target RC value, determine voltage change.
It should be noted that determining voltage tune according to the difference between the corresponding RC value in first area and target RC value
When whole value, difference is bigger, and corresponding voltage change is bigger.It, should when the corresponding RC value of second area is equal with target RC value
The voltage change of second area is 0, at this point it is possible to without adjusting the corresponding VGH voltage of the second area.
S404, according to voltage change, the corresponding VGH voltage in first area is adjusted, so that brightness and the mesh of first area
The difference marked between the brightness of the corresponding second area of RC value is less than preset value.
It, can be by target when adjusting the corresponding VGH voltage in first area it should be noted that according to voltage change
The brightness of the corresponding second area of RC value is as benchmark, i.e., without adjusting the corresponding VGH voltage of the second area, so that passing through tune
The corresponding VGH voltage in each first area is saved, so that the brightness of each first area second area corresponding with target RC value
It is close to get the brightness of the brightness second area corresponding with target RC value of each first area that difference between brightness is less than preset value
Like consistent.
It is exemplary, incorporated by reference to shown in following table 1, when adjusting the brightness in each region of panel, first area can be corresponded to
RC value be compared with target RC value, so that it is determined that the voltage change of first area, and according to the voltage change, adjustment
The corresponding VGH voltage in first area, so that between the brightness of the brightness of first area second area corresponding with target RC value
Difference is less than preset value.

In conjunction with table 1 as can be seen that being reference with L127 grayscale (511 ranks of 10bit), test obtains in each region M times
Brightness (M > 10) M brightness intrinsic brilliance of the mean value as the subregion, by the corresponding RC value in first area and target
When RC value is compared, since the RC value in region 1 is greater than the RC value in region 6, and the difference between the RC value in region 6 is 0.5,
It is corresponding, it can determine that the voltage change in region 1 is 2.5V, it at this time can will be according to voltage change 2.5V by region 1
VGH voltage 23.5V adjust to 26V so that the brightness in region 1 is approximate with the brightness in region 6 consistent；The RC value in region 2
Greater than the RC value in region 6, and the difference between the RC value in region 6 is 0.4, corresponding, can determine the voltage adjustment in region 2
Value is 2V, can will be adjusted the VGH voltage 24V in region 2 to 26V according to voltage change 2V at this time, so that region 2
Brightness it is approximate with the brightness in region 6 consistent；The RC value in region 3 is greater than the RC value in region 6, and between the RC value in region 6
Difference is 0.3, corresponding, can determine that the voltage change in region 3 is 1.5V, at this time can will be according to the voltage change
1.5V adjusts the VGH voltage 24.5V in region 3 to 26V, so that the brightness in region 3 is approximate with the brightness in region 6 consistent；
The RC value in region 4 is greater than the RC value in region 6, and the difference between the RC value in region 6 is 0.2, corresponding, can determine region
