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, 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 (gray scale without losing data). 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 Yidu direct LED display, 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. (1) the ambient temperature varies greatly. When the full-color LED display work itself must have a certain amount of heat, if the ambient temperature is too high heat and bad when the sun direct LED display, integrated circuits may not work properly direct LED display, LED display and even burned Jingzhou Direct , so that the display system does not work; (2) a wide audience, sight distance requirements far, wide field of view requirements, ambient light changes, in particular, may be subject to direct sunlight; (3) screen installed outdoors, the sun and the rain often leaching, wind dust cover, which the harsh environment, the electronic device is wet or damp can cause serious short circuit or fire, causing malfunction or a fire, resulting in the loss; (4) the display may be subject to strong electric magnetic attacks caused by lightning .
