LCD Display Color Process

White field color coordinate leveling is one of the most basic technology of full-color LED display. However, LCD Display in the mid 1990s, due to the lack of industry standards and basic testing methods, LCD Display usually only rely on the eye, based on the feeling to determine the white field color coordinates, resulting in serious bias and white color temperature of the random color. With the promulgation of industry standards and the completion of testing methods, many manufacturers began to standardize full-color color process. However, LCD Display there are still some manufacturers due to lack of color theory guidance, often at the expense of some of the base color gray level to allocate $number color coordinates, LCD Display comprehensive performance is not improved.

To sum up, we have mainly discussed three issues:

1, how to improve the color uniformity of LED HD display;

2, how to expand the gamut, to restore more natural color;

3, how to improve the color reduction of LED display;

The industry has a very wide range of applications, and in different application place to the LED's base wavelength has different requirements, for the LED color wavelength selection some is to achieve good visual effect, LCD Display some are to conform to people's habits, and some are industry standards, national standards and even international standards.

The above-mentioned chroma processing techniques are interrelated when they are implemented, and some of them are not even available for both fish and paws. LCD Display The integrated LED display is also necessary for brightness uniformity correction, gray-scale nonlinear transformation, noise reduction processing, image enhancement processing, dynamic pixel processing and so on, the whole signal processing process is very complex. Therefore, we must from the point of view of the system to comprehensively weigh the performance, grasp the order of the various processing, and increase the depth of signal processing, LCD Display in order to make Full-color LED display a colorful, colorful wonderful world.

For example, the selection of the wavelength of green nanotube-based in Full-color LED display; Early everyone generally choose the wavelength of 570nm yellow green LED, although the cost is low, LCD Display but the display color gamut, color reduction, low brightness. And after selecting the pure green tube with wavelength of 525nm, the color gamut of the display screen is enlarged nearly one times, LCD Display and the color reduction degree greatly improves, which greatly enhances the visual effect of the display.
