Chromatic aberration (Chromatic aberration; chromatic aberration): Chromatic aberration, also known as chromatic aberration, is a serious defect of lens imaging. In simple terms, chromatic aberration is the difference in color. When polychromatic light is used as the light source, monochromatic light does not produce chromatic aberration. . The wavelength range of visible light is about 400 to 700 nanometers. Lights of different wavelengths have different colors, and their refractive index when passing through the lens is also different. In this way, a point on the object side may form a color spot on the image side. Chromatic aberration generally has positional chromatic aberration and magnification chromatic aberration. Positional chromatic aberration causes the image to be viewed at any position with colored spots or halos, which makes the image ambiguous, and the magnification chromatic aberration causes the image to have colored edges. The main function of the optical system is achromatic.
It is the biggest problem facing LCD splicing products to show that the colors of LCD splicing are not different. Usually encountered such a situation, when dealing with problems such as color difference, technicians have to adjust dozens of monitors one by one. This is not only time-consuming and laborious, but also faced with a lack of uniform color reference standards, and the naked eye can identify tiredness and different monitors. There are many problems such as different color performance effects, which often result in exhaustion of time and manpower, but the color difference problem of splicing displays still exists. Recently, Shenzhen Leroy Digital, a pioneer in the LCD splicing industry, has launched a new "maintenance-free, black-out" LCD splicing series. It is understood that this series of products can not only successfully eliminate the problem of chromatic aberration differences in liquid crystal displays, but also can handle the technical bottleneck of traditional LCD splicing products that are difficult to maintain.
Since Samsung introduced ultra-narrow-edge LCD splicing, many domestic and foreign companies have successively expanded their business in different areas of LCD splicing. According to digital control information, the current DID narrow-edge LCD splicing display system mainly includes 46-inch LCD splicing and 55-inch LCD splicing. Two common specifications. The LCD splicing of these two specifications is the main digital product. Of course, it is not only digital, the LCD splicing display equipment launched by various LCD splicing manufacturers also mainly coils 46-inch LCD splicing and 55-inch LCD splicing with the narrow edge advantages of these two products to stop the extension of the business.
