From the commonly used warning screen to the door screen, outdoor full color display, indoor high-definition screen, full-color LED display applications continue to expand, the application of the display has been extended. Below we will first understand the main features of the full color LED display.

Full color LED display features

The full-color LED display is a kind of LED display. Its main features are:

(1) Rich color: It consists of three primary colors (red, green, blue) display unit plates, and 256 gray levels of red, green and blue each constitute 16,777,216 colors, which makes the electronic screen display rich in color, high saturation and high resolution. Dynamic image with high display frequency;

(2) Good effect: using nonlinear correction technology, the image is clearer and the layering is stronger;

(3) Strong reliability: using distributed scanning technology and modular design technology, reliability and stability are higher;

(4) Super detection function: real-time detection of whether the pixel points in the screen are invalid, and the working state of the pixel is remotely transmitted;

(5) The new mask design makes the light emitted by the LED almost zero reflection, ensuring the display effect of the screen;

(6) High flatness: the flatness coefficient of the box is <0.5mm, and the power factor is as high as 88 or more;

(7) Diversified input signals: support stage signals such as RF, S-VIDIEO, RGBTV, YUT, YC, COMPOSITION;

(8) High waterproof performance: waterproof aprons on the back of the module, high-quality imported glue on the front for filling;

(9) Durability: High-temperature spraying technology is adopted to greatly improve the anti-rust function; the light-emitting module is guaranteed for ten years, the mask is not reflective, and it is resistant to ultraviolet rays, and does not fade for five years.

Copper smelting methods can be divided into two categories: pyrometallurgy and hydrometallurgy. More than 85% of the world's refined copper output is recovered from pyrophyllite concentrates and recycled copper by pyrometallurgical process, and the refined copper produced by hydrometallurgy only accounts for about 15%.

In China, copper metal is extracted from copper concentrates mainly by the pyrometallurgical method. The more advanced one is flash smelting, whose output accounts for over 30% of the total copper produced in the country. Due to low energy consumption, large-scale, can effectively control the advantages of environmental pollution. This smelting technology is being developed in the copper industry. Flash smelting furnace according to different working principle can be divided into two types: Outokumpu flash melting, InCo flash melting. The following describes Outokumpu smelting process.
