For ease of being more clearly understood that the brightness adjusting method of the display screen of first embodiment of the invention, below will be especially exemplified by tool
Style is described in detail.
Assuming that display resolution is 640*640, it is 128* that its display control card such as receiving card band carries area size
128.Multiple fritters that preferably be divided into for receiving card band load regional simulation by the embodiment of the present invention are bright for unit regulation display screen
Degree：For example, each receiving card band carries region (128*128) and is modeled and is divided into multiple 8*8 fritters, then whole display screen viewing area
Domain can be divided into 80*80 8*8 fritter, and each 8*8 fritter is to that should have a brightness adjustment, then the image transition after processing is equal
It is even, in the absence of obvious bulk effect.Below to simplify explanation, it is that unit is simulated along line direction that every receiving card is arranged with M
It is divided into fritter.
(1), principle explanation：
Here by taking the screen of court as an example, illustrate the embodiment of the present invention realizes step；It is well known that the control of LED display
Realized typically by multiple receiving cards, each receives card control/a part of viewing area with LED display is carried.
The present embodiment captures the illumination data that the receiving card band carries region by configuring one or more light probes for every receiving card
(namely intensity of illumination data), then average to the illumination data that individual receiving card is obtained and obtain average illumination as the reception
Cassette tape carries the illumination in region；Because the illumination data for collecting there may be error, it is therefore desirable to the average of all receiving cards
Illumination carries out LPF, to ensure the flatness of average illumination；Then closed according to the illumination and brightness ratio appointed in advance
It is table Table (such as shown in Fig. 2, the 1st is classified as illumination, and the 2nd is classified as brightness ratio) and brightness ratio identical columns M, meter
(wherein Table (i, 1) represents the illumination of the i-th row in Fig. 2 to the brightness ratio of calculation row per M, and Table (i, 2) represents corresponding i-th row
The brightness ratio of illumination)；The brightness ratio that will finally calculate is applied on correspondence M row LED point.Wherein, every receiving card
The light probe quantity of configuration can be with identical, it is also possible to different.
(2), brightness adjusting method flow：
A () gathers the initial illumination data [IntensityValue that every receiving card is captured by light probe1,
IntensityValue2,...,IntensityValueN], individual receiving card is set herein is configured with N number of light probe；
B () calculates every initial illumination data average of receiving card collection to obtain the average illumination of receiving card
IntensityAvg；
C () is the influence of the deviation of the initial illumination data that guarantee is collected, to all receiving cards of LED display configuration
Average illumination carry out LPF to obtain average illumination IntensityFinal after every filtering of receiving card, to ensure number
According to flatness；Exclude the influence of abnormal illumination data；The main purpose of LPF is to carry out abnormal mean illumination herein
Amendment, because there may be the situation of light probe failure in actual applications, if having been acknowledged in advance certainly, light probe is normal,
It is contemplated that omit the LPF step.
D () calculates every receiving card and exists according to the illumination and brightness ratio relation table (such as shown in Fig. 2) being previously set
Brightness ratio under correspondence illumination IntensityFinal, can calculate according to bilinear interpolation here：
Assuming that the illumination data of receiving card to be solved is IntensityFinal, it is located at illumination and brightness ratio relation table
Between the Nth row and N+1 rows of (such as shown in Fig. 2), then the brightness ratio of the receiving card is calculated as follows：

IntensityFinal-Table(N,1)；
2) distance of N+1 row brightness values is Dis2=in receiving card illumination data IntensityFinal distance relation tables
Table(N+1,1)-IntensityFinal；
3) coefficient of bilinear interpolation is respectively Coef1=Dis2/ (Dis1+Dis2), Coef2=Dis1/ (Dis1+
Dis2)；

×Table(N,2)+Coef2×Table(N+1,2)。
Each receiving card is calculated according to step (d) realize the brightness ratio under correspondence illumination IntensityFinal；
Herein it is understood that in the receiving card illumination data IntensityFinal just energy in illumination and brightness ratio relation table
Enough directly inquiries are obtained, then need not carry out interpolation calculation.
E (), according to the brightness ratio identical columns M for setting, the realization of every M row LED point is bright on calculating receiving card
Degree ratio：
1) assume that adjacent two receiving card is respectively according to the illumination corresponding brightness ratio that step (d) is calculated
BrightnessValue1 and BrightnessValue2, adjacent two receiving card bands carry for example adjacent two receptions between region
Between two edges being located remotely from each other in cassette tape load region, between adjacent two receiving card bands load regional center etc., and be preferably
LED points with carrying between regional center are TotalNum, then the LED point between two receiving card band load regional centers can
Group number as unit is arranged as DivisionNum=ceil (TotalNum/M) to mark off with M, and (ceil represents the letter that rounds up
Number)；
2) the brightness ratio difference value per adjacent M row LED point is Diff=(BrightnessValue2-
BrightnessValue1)/DivisionNum；
3) brightness ratio that final each M row LED point is realized is：BrightnessPerDivisionDivisionCount
=BrightnessValue1+ (DivisionCount-1) × Diff, wherein DivisionCount represent which M is arranged, model
Enclose is [1, DivisionNum].
Calculated to every brightness ratio of receiving card each M row LED point according to step (e).
F () finally acts on the brightness ratio for calculating on LED display, the effect needed for realizing.
Additionally, it is noted that diversity and the diversity to brightness demand in order to be applicable practical matter, here
Using the illumination shown in Fig. 2 and brightness ratio relation table Table and brightness ratio identical columns as the revisable number of user
According to.
Furthermore, it is worth mentioning at this point that, present invention is not limited to using per M row brightness ratios identical side
Formula, it is also possible to M × M as minimum unit, correspondingly can calculate every M row LED of each receiving card according to step (e)
After the brightness ratio of point, then the bright of the every M rows LED point of calculating the step of similar to step (b) and step (e) is done in a column direction
Degree ratio, so as to be calculated the brightness ratio of every M × M minimum unit.Certainly, M × M minimum units can also be replaced and embarked on journey
The different block of cells of LED points on column direction.
