Fig. 2-1 is the flow chart of the display packing of another kind of display floater according to an exemplary embodiment.This shows
Show that the display packing of panel can include following several steps：
In step 201, obtain the brightness of display floater.
In the display packing of the display floater provided using the embodiment of the present disclosure, the bright of display floater can be obtained first
Degree, the brightness of the display floater refers to the overall brightness of display floater, and the overall brightness can be the current bright of display floater
The percentage ratio of the maximum brightness value of angle value and display floater, the unit of brightness value can be per square metre of candelas (cd/m2).

Brightness it is relatively low when, drive that the electric current of the luminescence unit of display floater is less, the concordance of display floater is poor, thus control group
When the brightness of display floater is less than predetermined luminance, part can determine that display floater is in low current driving condition.
When driving the electric current of the luminescence unit of display floater less, when the driving current of different luminescence units has differences,
The shared percentage ratio in the driving current of each luminescence unit of the difference can be than larger, therefore the difference is for luminescence unit
Brightness affects also the concordance of display floater can be caused relatively low than larger.Exemplary, the driving current of luminescence unit A is 1 milli
Peace, the driving current of luminescence unit B is 2 milliamperes, and gap is 1 milliampere, driving of this 1 milliampere gap equivalent to luminescence unit A
The 100% of electric current, 50% of the driving current equivalent to luminescence unit B, this light sent by the two luminescence units it is bright
The impact of degree is huge, and the driving current for working as luminescence unit A is 10 milliamperes, and the driving current of luminescence unit B is 11 milliamperes
When, gap is still 1 milliampere, but this 1 milliampere equivalent to the 10% of luminescence unit A driving currents, equivalent to the driving of luminescence unit B
9% of electric current or so, the difference are less for the impact of the brightness of the light that the two luminescence units send.

Control assembly can obtain the average gray-scale value of each pixel clusters in the image that display floater shows, any of which picture
Plain cluster can include sub-pixel, a pixel or a multiple pixels including at least one sub-pixel, i.e. each pixel clusters.
And the average gray-scale value of each pixel clusters can be the arithmetic mean of instantaneous value of the grey decision-making of all sub-pixels in pixel clusters, geometric average
Value, mean square, harmonic-mean or weighted mean etc..
Display floater can be that, come display image, each pixel shows a color by multiple pixels of array arrangement
Block, and each pixel is that (each pixel can include three sub-pixels of RGB, or including RGB by multiple sub-pixels
White four sub-pixels) constitute, each sub-pixel can have a grey decision-making, and the grey decision-making represents the brightness of each sub-pixel
Rank, grey decision-making are lower, and gray scale is lower.Exemplary, when GTG has 256 grades, the scope of grey decision-making is just 0-255,0
For most secretly, 255 is most bright.
Sub-step 2042, obtain average gray-scale value in the image that shows of display floater less than the pixel clusters of preset gray scale value and
The number ratio of all pixels cluster in the image that display floater shows.Perform sub-step 2043.
It is considered that average gray-scale value is less than in the pixel clusters of preset gray scale value, the driving current of luminescence unit is less than electric current
Preset value, control assembly can obtain average gray-scale value in the image that display floater shows less than preset gray scale value pixel clusters with
The number ratio of all pixels cluster in the image that display floater shows, during the number ratio can reflect display floater, driving current is little
In the ratio of the luminescence unit of electric current preset value.
Whether sub-step 2043, judge the number than more than default ratio.When the number ratio is more than default ratio, perform
Sub-step 2044, when the number is than no more than default ratio, performs sub-step 2045.
Control assembly may determine that the number than whether more than default ratio, and according to structure is judged performing different steps
Suddenly.
Sub-step 2044, determines that display floater is in low current driving condition.
In the image that display floater shows, average gray-scale value is all with the image less than the pixel clusters of preset gray scale value
When the number ratio of pixel clusters is more than default ratio, it is believed that the driving current of the luminescence unit of the predetermined number of display floater is low
In electric current preset value, control assembly can determine that display floater is in low current driving condition.Wherein, predetermined number and electric current are pre-
If value can be determined previously according to concordance of the luminescence unit in display floater under the driving of different electric currents.
Sub-step 2045, determines that display floater is not at low current driving condition.
In the image that display floater shows, average gray-scale value is all with the image less than the pixel clusters of preset gray scale value
When the number of pixel clusters is than no more than default ratio, it is believed that there is no the drive of the luminescence unit of predetermined number in display floater
Streaming current is less than electric current preset value, and control assembly can determine that display floater is not at low current driving condition.
As in Figure 2-4, second embodiment includes following 4 sub-steps：
Sub-step 2046, obtains the average gray-scale value of the image that display floater shows.Execution step 2047.
The average gray-scale value of the image that display floater shows can be all sub-pixels in the image that display floater shows
The meansigma methodss of grey decision-making, the meansigma methodss can be the arithmetic mean of instantaneous value of all sub-pixels, geometrical mean, mean square, tune
With meansigma methodss or weighted mean etc..
Exemplary, with arithmetic mean of instantaneous value, the image that display floater shows has 1000 sub-pixels, sub by this 1000
The grey decision-making of pixel is added again divided by 1000 average gray-scale values that the image that display floater shows is obtained.
Sub-step 2047, judge average gray-scale value whether less than default meansigma methodss.It is average less than default in average gray-scale value
During value, sub-step 2048 is performed；When average gray-scale value is not less than default meansigma methodss, sub-step 2049 is performed.
Whether control assembly may determine that average gray-scale value less than default meansigma methodss, and be performed according to judged result different
Step.
Sub-step 2048, determines that display floater is in low current driving condition.
When the meansigma methodss of the grey decision-making of all sub-pixels are less than default meansigma methodss, it is believed that default of display floater
The driving current of several luminescence units is less than electric current preset value, and control assembly can determine that display floater drives shape in low current
State.
Sub-step 2049, determines that display floater is not at low current driving condition.
When the meansigma methodss of the grey decision-making of all sub-pixels are not less than default meansigma methodss, it is believed that do not deposit in display floater
Electric current preset value is less than in the driving current of the luminescence unit of predetermined number, it is low that control assembly can determine that display floater is not at
Electric current driving condition.
In step 205, adjust the gamma value of display floater so that the gamma value after adjustment is less than acquiescence gamma value.
When display floater is in low current driving condition, control assembly can adjust the gamma value of display floater so that
Gamma value after adjustment is less than acquiescence gamma value.
When signal is shown to display floater input, the image that display floater shows can be with the image described in display signal
There is certain distortion, in order to correct the distortion, can be with Gamma correction (English：Gamma Correction) technology is to display surface
A default gamma (the English of plate：Gamma) value, the brightness of the gamma value and display floater display picture are negatively correlated, for according to
Certain function curve lifts the brightness of the picture that display floater shows, and carrys out correction chart picture with this, makes what display floater showed
Image is closer to the image shown described in signal.As shown in Figure 2-5, when which is different gamma values, the GTG of luminescence unit
The graph of relation of the brightness of value and luminescence unit, wherein, transverse axis represents grey decision-making (may range from 0-255), from left to right
Increase, the longitudinal axis represent brightness (brightness can be the normalized value of the brightness of display floater), increase from bottom to up, and curve q1 is gal
Relation curve when value of gamma is 1.8, curve q2 are relation curve of gamma value when being 2.0, and curve q3 is gamma value when being 2.2
Relation curve, by Fig. 2-5 as can be seen that after reducing gamma value, the brightness of driven for emitting lights unit can become big.
Step 205 can include following two embodiment.
As shown in figures 2-6, the first embodiment includes following 3 sub-steps：
Sub-step 2051, obtains the average gray-scale value of the image that display floater shows.
When gamma value is adjusted, control assembly can obtain the average gray-scale value of the image that display floater shows.If control
Component processed obtains average gray-scale value in the sub-step 2046 of step 204, then can directly read sub-step in this step
The average gray-scale value obtained in 2046, if control assembly does not obtain average gray-scale value in sub-step 2046, in this step
The mode that may be referred in sub-step 2046 obtains average gray-scale value.
Sub-step 2052, according to default grey decision-making and the corresponding relation of gamma value, determines corresponding to average gray-scale value
