LED luminous color and luminous efficiency and production of LED materials and processes related to the beginning of all light blue ball, plus phosphor back, depending on the needs of the user to adjust the different light color, red is widely used , green, blue, yellow four. Because LED low voltage (only 1.2 ~ 4.0V), capable of self-luminous and have a certain brightness, Brightness and voltage (or current) regulation, which itself has impact resistance, anti-vibration, long life (100,000 hours) Yichang display Which is good, so the large display device, there is no other way to display and LED display match. Gradation nonlinear transformation means in accordance with the gradation data arithmetic empirical data or some non-linear relationship between the conversion and then supplied to the monitor display. As the LED linear devices, and non-linear display characteristics different from traditional monitors. In order to make possible consistent with the traditional LED display data source without loss of gray level Yichang display quality, typically in the LED display will do after a system-level non-linear transformation of the gray-scale data, the transformed data will increase the number of bits (guaranteed gradation data is not lost). Some domestic control system supplier so-called gray 4096 or 16384 gray or higher mean after all the nonlinear transformation gray space. 4096 is the adoption of eight sources to the 12 space technology nonlinear transformation, 16384 is the use of 8-16 non-linear transformation technology. From 8 sources as nonlinear transformation, the converted space is definitely bigger than the eight source. Generally at least 10. As gray as this parameter is not bigger is better, generally 12 can do enough transformed.
