LED display have many forms, such as LED unit board, single color led display, dual color led display, full color LED display, etc. If the led screen display is not more clear, it will affect the overall results directly. So how do we make the display more clearly. Gray scale, contrast, refresh rate and other technical indicators directly affect full color LED display effect.
1. The gray level
Gray level is a single color led display brightness series from the darkest to brightest, the higher LED display gray level, the more beautiful and richer color. Gray level increasing can enhance the color depth and make image color levels increasing. The control level of LED gray between 14 bit and 16 bit, it make high-end display resolution details and display results reached the world advanced level. With the development of hardware technology, LED gray scale will continue to higher control precision development.
2. Contrast enhancement
Contrast is one of the key factors affecting the visual effect, generally the higher contrast, the image more clear. High contrast is good for image clarity, detail performance and gray levels. High contrast led display in black and white contrast, clarity and completeness have great advantages
The method of improved LED display
1. Increasing the brightness of the LED display
The brightness of the LED display in some occasions and not the higher the better. For indoor LED display, if too bright, it will make light pollution and damage to the observer's eye.
2. Reduce the surface reflectivity of the LED display
Making special treatment with LED panel and LED light tube, reducing reflectivity of LED panel and improving the LED display contrast.
