Certain optical properties of the crystal. LCD in 1888 by the Austrian botanist Reinitzer found between a solid and a liquid, with the rules of the molecular arrangement of organic compounds, the liquid crystal molecules arranged in a certain order, led display, and this sequence of external conditions, such as temperature, are very sensitive to changes in the electromagnetic field. Under the action of an electric field, liquid crystal molecules are arranged will change, thus affecting its optical properties, a phenomenon known as electro-optic effect. LDX advertising: LED display brightness color uniformity problem has plagued the industry since a major problem, is generally believed that the uneven brightness of the LED can be a single point calibration to improve brightness uniformity and color non-uniformity can not be correction, only through the LED color coordinates segmentation and filtering to improve. As people increasingly high demand for LED display, LED color coordinates only to be broken down and screening has been unable to meet the people critical eye on the integrated display correction, chroma uniformity improvement is achievable a. First, due to the different LED itself results in a certain level of luminance and chrominance are inconsistent (for example: using the same current lighting the same production batch two green LED, there may be 30% of the brightness variations, the wavelength may Changes will 10-15nm). Secondly, after a period of use blue LED dims the greatest extent, the red led display quotes Taiyuan minimum, but the biggest problem is after a period of time in different degrees LED dims. Therefore, even if the LED screen in the factory is the perfect consistency Taiyuan color led display, but with the LED dims Taiyuan led display system, consistency will be lost, inconsistent after three years of non-stop use LED screen resistance will be a significant discovery. To do this, use the world's most advanced monochrome luminance and chrominance correction technology (also known as: luminance and chrominance signature technology), to solve color color inconsistencies due to different color light-emitting diode attenuator brought inconsistent. By-point calibration system is an integrated LED display can for each pixel measurement and calibration software and hardware system that can provide the entire screen of each pixel brightness and color correction to achieve consistent performance characteristics.
