LED display to show a more clear a few tips

LED display can be divided into many types, such as: LED unit board, led monochrome display, double color LED display screen, screen printing, full-color LED display and so on. If the LED display effect is not more clear, it will directly affect the overall effect of LED display. So how can we let the LED display shows more clearly, let LED display experts for everyone support weapon.

LED full-color display of gradation, contrast, refresh frequency and other technical indicators the level directly affect the display effect of LED full color display. Gray level refers to the single color LED display screen brightness between from the dark to the brightest to different brightness series, LED display screen of the gray level is high, color is more rich, color more gorgeous; on the contrary, the display color of a single, simple changes. Improved gray level, can greatly enhance the color depth, so that the image color display level increased geometric number. LED grayscale control level is 14bit~16bit, which makes the image level resolution details and display results of the high-end display products reach the world advanced level. With the development of hardware technology, the LED gray level will continue to develop to a higher control precision.

contrast is one of the key factors that affect the visual effect, in general, the higher the contrast, the more clear the image, the more bright color. High contrast for image clarity, detail performance, gray level performance has a great help. In some of the larger black and white contrast text, video display, high contrast led display in black and white contrast, clarity, integrity and other aspects have the advantage. Contrast for dynamic video display effect on some of the larger, due to the dynamic image of bright and dark conversion faster, higher contrast ratio, eyes more easy to distinguish this conversion process.

enhance the display contrast of two kinds of main methods: (1)

(2) to reduce the LED display surface reflectance is mainly in the LED panel and LED light emitting tube for special processing, reduce the LED panel reflectivity, and thus improve the contrast of LED display. NX series point spacing of LED 4mm full color high-end display, from the original process of 950:1 to 4000:1, so that the product in contrast to the key indicators have been greatly improved.
