LED display - knowledge
LED display since its birth has attracted much attention, along with the advance of the installation technology in recent years, the application has been approved by many industry fields.
LED display production and maintenance also needs professional knowledge.
The LED display show how to realize the hd?
In fact to achieve high-resolution display must have four factors, the following is the small make up to analyze the four elements which is for everyone.
A, improve the contrast of full-color LED display, contrast is one of the key factors affecting the visual effects, generally the higher the contrast, the clearer image lifelike, strong color more gorgeous.
High contrast for image clarity, details of performance, the gray level are of great help.
Full color LED display contrast enhance mainly is to improve the brightness of the LED display, and reduce the screen surface reflectivity, however, the higher the brightness is not better, is too high, but counterproductive, will not only affect the service life of LED display, also can cause adverse effects of light pollution to environment and crowd.
Full-color LED display, LED panel and LED tube to carry on the special craft processing, can reduce the reflectance of LED panel, also can improve the contrast of full-color LED display.
Second, improve the full-color LED display screen to grayscale, grey scale refers to the full color LED from the darkest to the brightest in the single color brightness can distinguish between the brightness of the series, full-color LED display gray level is higher, the color is rich, colour is gorgeous;
On the other hand, according to a single color, simple changes.
Grey level enhancement, can greatly enhance the color depth, making image color shows an geometric increase in the number of levels.
Three, to narrow the points spacing, full-color LED display screen to narrow the points spacing, full-color LED display screen can be very good to improve the clarity, full-color LED display point spacing is smaller, LED display pixel density per unit area is higher, can show more details, it showed more exquisite.
Four, full-color LED display screen and video processor, LED video processor can use advanced algorithm of image quality is not good signal to the decoration of execution to interlaced, edge sharpening, motion compensation and so on a series of processing, enhance the detail of the image, improve image quality.
Video processor image scaling processing algorithm, was used to ensure video images after scaling processing, maximum keep the image resolution and gray levels.
In addition, you also need to video processor has rich image adjustment options and adjustment effect, to deal with image brightness, contrast, gray level, in order to make sure the screen output soft clear picture.
