Color, brightness and angle of view
With the combination of diodes and semiconductors, their production materials and processes are gradually upgraded, breaking through the limitations of the original brightness and color, and a large number of blue diodes and pure green light-emitting diodes are used to improve the brightness of the display effect. Further, it can improve the advantages of LED display in outdoor environment, adapt to different display needs, and improve the effective value of LED in different environments. The evaluation of LED display performance must be the result of comprehensive consideration, because relevant performance indicators are closely related, and indicators such as brightness, visual angle and resolution affect each other. At present, surface mounted LED devices are used in high-density, full-color indoor displays to improve the visual angle and brightness performance of the display.
Gray scale
The gray level of LED display screen is mainly used to evaluate its color authenticity. The display color is evaluated according to the gray level by judging the brightness level between the darkest single primary color and the lightest single primary color. When the gray scale is high, the display color is rich; When the gray level is low, the color change is single. Therefore, the increase of gray level is conducive to improving the color display level and color depth of the image. Improvement of.
contrast ratio
The contrast of the display affects the visual imaging effect. High contrast can improve the definition of the picture, bright colors, and effectively improve the quality of image details, clarity and grayscale. In addition, contrast also affects the resolution of dynamic video. To some extent, high contrast can make it easier for the naked eye to distinguish the light dark transition process in dynamic images.
