DMD control module characteristics:
One, colour consistency system:
Because of the material behavior of LED, the luminance of every LEDs there are differences.While how to guarantee to produce in enormous quantities, the consistance of every video machine on color is very important link.An our cover software and hardware system brief introduction of exploitation is as follows:
At first require to determine preliminary Duty cycle, show colour gamut, brightness etc. according to characteristic, system power dissipation, the product Show Color of the RGB LED body that uses on ray machine.All these data are inputed in the data model of building up in advance in conjunction with the LED driveability parameter that adopts simultaneously, computing obtains preliminary LED sequence.The PCBA LEDsequence that rear use obtains that returns, the some electronic bright bare engine, measure the light coordinate brightness value of actual displayed simultaneously with chroma meter under the state that shows RGB three pure colors and white.Again according to the needed parameter differences of actual measured value and expection, thereby the corresponding parameter of the data model of building is adjusted, drive ray machine with the new LED sequence of data model output after adjusting again and measure with chroma meter simultaneously, the parameters such as the actual light coordinate brightness value that obtains like this can reach desired requirement gradually.
There is LED and various parts parameter characteristic deviation to some extent within the specific limits for when batch production, the data model of in data model, the deviate input being built, so just can obtain a lot of LED sequences, thus in theory when volume production arbitrary machine always can find suitable one group to reach same display effect in the LED sequences database that obtains when reality is exported.
In formal production, every machine can be done a calibration actions:, with the light coordinate brightness value under chroma meter measurement RGB three pure colors and white states, by a cover tool and tool software, adjust the LED electric current and select suitable LED sequence; The parameter that to finally determine finally is cured in the storer of every machine intimate, can automatically record simultaneously the corresponding measured value of luminance brightness sensor under each state, uses during in order to follow-up automatic calibration.
Annotate:
Duty cycle refers to each primary colours of RGB are opened in one-period unit interval sheet time and the ratio of whole unit interval sheet.The duty cycles sum of RGB three looks is 1.
Two: auto color/white balance correction:
After long-time use, each parts of projection computer (LED, main board elements etc.) can produce certain performance change, cause final display effect and the initial difference that produces; Thereby the skew of colour cast and the white balance point of color appears.
We are provided with the luminance brightness sensor in system, each LED luminance brightness of RGB of meeting real-time monitoring system, and with initial value, compare, depart from certain value as difference and can revise to reach the constant function of long-time use color.Working method is as follows:
Each start time luminance sensor light sensor can monitor the luminance brightness of each LED of RGA, and the raw data when dispatching from the factory compares, and draws the brightness number difference that the decay of LED lamp produces; Then automatically select by the software of special exploitation the data sequence that is complementary with current LED characteristic.Also implanted the LED monochrome information when software can record each shutdown automatically in system, and set up table list, data and Benchmark brightness value that when start shooting next time, system was transferred while shutting down last time are compared, if necessary, system will be adjusted the power supply of each LED lamp of RGA automatically to guarantee the consistent of white balance point.
