Subsequently, at next step 104, executing state is provided with step, comprises that the control LCD gets into white screen show state.For ease of accurately measuring the brightness of LCD, technical scheme provided by the invention at first places white screen show state with LCD.However, those skilled in the art should be understood that in concrete implementation procedure, for measuring the brightness of LCD, also can LCD be placed under other color show states.
Subsequently, at next step 106, carry out initialization step, its idiographic flow is as shown in Figure 2.
Fig. 2 is the process flow diagram according to the initial method 200 of the present invention's one preferred embodiment.As shown in Figure 2, initial method 200 starts from step 202.
Subsequently,, the input backlight value is set at the initial value that is provided with in advance, carries out measuring operation then at next step 204.
In actual mechanical process, the boundary luminances value comprises the brightness upper limit and two boundary values of brightness lower limit, and the adjustable brightness range of LCD is just by the brightness upper limit and the decision of brightness lower limit.For the different brightness boundary value, need in step 202, select the initial value corresponding with it, promptly when confirming the backlight value of brightness upper limit correspondence, set initial value should be the pairing initial value of the brightness upper limit; When confirming the backlight value of brightness lower limit correspondence, set initial value should be the pairing initial value of brightness lower limit.For example, the brightness of supposing backlight is at 0cd/m
2～350cd/m
2Between, and selected scope is 10cd/m
2～300cd/m
2, then be limited to 10cd/m under its brightness
2, be limited to 300cd/m in the brightness
2, promptly its boundary luminances value is 10cd/m
2And 300cd/m
2Therefore; In step 202; Should the input backlight value be set at and the corresponding initial value that is provided with in advance of boundary luminances value (the brightness upper limit or brightness are rolled off the production line),, should the input backlight value be set at the initial value that in advance be provided with corresponding with the brightness lower limit promptly for the brightness lower limit; For the brightness upper limit, should the input backlight value be set at the initial value that in advance be provided with corresponding with the brightness upper limit.In concrete implementation procedure; The corresponding initial value of boundary luminances value can be provided with according to experience in advance, for example is limited to example with under the brightness, can select an enough low backlight value as initial value; So that on all LCDs to be calibrated, the brightness value of this initial value correspondence is all less than the brightness lower limit; In like manner, for the brightness upper limit, also can select an enough low backlight value as initial value, so that on all LCDs to be calibrated, the corresponding brightness value of this initial value is all less than the brightness upper limit.Hence one can see that, and the brightness value of LCD under initial value is less than the boundary luminances value.
In concrete implementation procedure, measuring operation comprises measures the brightness value of LCD under the input backlight value, and input backlight value and the brightness value that records are added in the backlight illumination table of comparisons.
In concrete implementation procedure, the backlight illumination table of comparisons can adopt following form:
| Backlight value | Brightness value |

Subsequently, at next step 206, improve the input backlight value, and carry out measuring operation with the step value that is provided with in advance.
Subsequently, at next step 208, whether the measured brightness value of measuring operation is greater than the boundary luminances value, if then forward step 210 in the determining step 206; Otherwise, get back to step 206.Hence one can see that, and in method 200, the brightness value of LCD under the input backlight value that after repeatedly improving, finally obtains will be higher than the boundary luminances value.Hence one can see that, and the boundary luminances value is between the corresponding brightness value of the corresponding brightness value of initial value and input backlight value end value.Can be seen from the foregoing, write down a plurality of backlight value that begin from initial value in the backlight illumination table of comparisons, also write down the corresponding intrinsic brilliance value of each backlight value simultaneously, and the intrinsic brilliance value of maximum backlight value correspondence is greater than the boundary luminances value.So; In fact the backlight illumination table of comparisons reflects the brightness value of LCD under a series of backlight value; And both comprised the backlight value that pairing brightness value is lower than the boundary luminances value among these backlight value; Also comprise the backlight value that pairing brightness value is higher than the boundary luminances value, therefore come match backlight liquid crystal display brightness model (being the backlight illumination curve) according to this backlight illumination table of comparisons, its result is with the true backlight brightness curve of ten minutes near LCD.
At last, method 200 ends at step 210.
Get back to method 100 now.After execution of step 106, method 100 forwards step 108 to, carries out calibration steps, and its idiographic flow is as shown in Figure 3.
Fig. 3 is the process flow diagram according to the calibration steps 300 of the present invention's one preferred embodiment.As shown in Figure 3, method 300 starts from step 302.
Subsequently, at next step 304, carry out the match evaluate operation, and operating result is labeled as the benchmark result based on the backlight illumination table of comparisons.
In concrete implementation procedure; The match evaluate operation comprises; According to the backlight illumination table of comparisons, generate the backlight illumination model based on the cubic spline interpolation algorithm through initial model, and according to the backlight illumination model search as operating result near backlight value; Wherein this corresponding brightness value is near the boundary luminances value in the backlight illumination model near backlight value, wherein initial model is:
In above-mentioned initial model S (x), x is the backlight value that writes down in the backlight illumination table of comparisons, and y is the corresponding brightness value of x in the backlight illumination table of comparisons, M
jBe y
jAt x
jThe second derivative at place, h
jBe x
J+1-x
jValue, wherein j 0,1...., n-1.
As indicated above, near backlight value in the backlight illumination model corresponding brightness value near the boundary luminances value.Because the backlight illumination model that generates is a continuous curve; And in concrete implementation procedure; Each backlight value in the LCD adjustable extent is generally integer; Therefore can't use the boundary luminances value directly through the corresponding backlight value of backlight illumination Model Calculation (because result of calculation is likely decimal), and can only adopt method provided by the invention, use near backlight value.
Subsequently,, will import backlight value and be set at the benchmark result, carry out measuring operation then at next step 306.
Subsequently,, carry out the match evaluate operation, obtain operating result, and judge whether this operating result equates with the benchmark result, if then forward step 310 to, otherwise forward step 312 to based on the backlight illumination table of comparisons at next step 308.Through another time match evaluate operation, make the backlight illumination model obtain more near the actual backlight illumination curve of LCD.
As indicated above, if equate with the benchmark result, then forward step 310 in step 308 decision operation result, the corresponding backlight value of boundary luminances value is set to the benchmark result, forwards step 314 then to.
As indicated above, if unequal, then forward step 312 in step 308 decision operation result and benchmark result, according to this operating result the benchmark result is replaced, get back to step 306 then.
At last, method 300 ends at step 314.
The present invention also provides a kind of LCD brightness calibrating installation, just combines Fig. 4 described below.
