Question:
Recently LED Screenmaker anounce for LED Video screen Grayscale function.
14~16bit Grayscale for each color and reflashrate 1000Hz etc.
I dont' understanding how to LED Brightness PWM Controle above high spec.
Would you mind teach to me PWM Controle methode and algorithme ?
Or...
Do you know this Problem ? Answer to me cause and solution.
Fig1 : Video Server SDI Source
Fig2 : Another Video Server SDI Source
Scene1 top is black.
Why is same scene different ? What is cause and solution ?
Please answer to me look forward.
Who have a KS0127B Apllication Sheet?
I am first try this device. I want to know a apllication circuit and component layout.
My first design sample is designed by referance circuit in KS0127B datasheet.
But sometime this device is dead or internal register erasing at power on
and off. I think...
atmel at29 flash write
Now, I am testing for Flash memory(AT29c256), but not working.
How to using for flash memory. Where I can found MCS51 source file.
Do anyone have a experiance for LED color correction methode or
algorithm. I have try it but very difficult. Anyone help me.
This Color correction means for each pixel color differancial and
luminunce differencial. Not mean the Whole screen color correction.

Thanks roadster
What is a LED Drive IC from TexasInstrument. TLC5911 or anyone? Please explain for DSP processor purpose function.
I want know more detail.
Generaly video processor is output 10bit RGB after Gamma correction for 8bit RGB. Is this meaning realy 10bit. What is this for...
techie
1st quation meaning really 16bit . Generally decoder output is 8bit, but
after Gamma correct by LUT. Actually ADConverting is not 10 or 16bit.
2nd quastion is meaning, actually LED have a problem brightness and color variation problem in same current and same Pulsewidth(by data)...
Dear romanp.
I have 2 quastion.
One is how to make 16bit pixel data.
Another one is how to control color and brightness of
each LED cluster. How to obtain Same color and brightness.
