RGB LED for full-color LED display

Guide: Full-color LED display normally made by RGB LED. Best LED factory produce kinds of RGB LED with diferent size, like: 5mm RGB LED through-hole LED, 8mm RGB LEDthrough-hole LED, 3mm RGB LEDthrough-hole LED, 5050 RGB LED, 2835 RGB LED, 3535 RGB LED, 2727 RGB LED, 2020 RGB LED, 1010 RGB LED, 3528 RGB LED ect. And all of this RGB LED can widely work for LED display. Full color LED has now become more and more important in people's lives. Because of its advantages, full-color LED display is more and more popular. However, because of the irresponsibility of individual manufacturers, there has been a full-color LED display with different quality on the market. The following small series will introduce you how to identify the quality of the full-color LED display and how to maintain the full-color LED display. .

How to identify the quality of a full-color LED display:

The quality of a full-color display can be signed from the following aspects:

1 flatness

The surface flatness of the full-color LED display should be within ±1mm to ensure that the displayed image is not distorted. Local protrusion or recession may cause the viewing angle of the display to appear dead angle.

2 brightness and viewing angle

The brightness of the indoor full-color LED display should be above 800cd/m2, and the brightness of the outdoor full-color LED display should be above 1500cd/m2 to ensure the normal operation of the full-color LED display. Otherwise, the brightness will be too low. Clear the image displayed. The size of the viewing angle directly determines the number of full-color LED display audiences, so the bigger the better.

3 white balance effect

The white balance effect is one of the most important indicators of a full-color LED display. In color theory, when the ratio of the three primary colors of red, green and blue is 1:4.6:0.16, pure white will be displayed. If there is a slight deviation in the actual ratio, the deviation of white balance will occur. Generally, it should be noted whether white is blue or yellow. Green phenomenon. The quality of the white balance is mainly determined by the control system of the LED display, and the lamp beads also have an effect on the color reproduction.

4 color reduction

The redness of color refers to the color reproduction of the full-color LED display, that is, the color displayed by the full-color LED display should be highly consistent with the color of the source, so as to ensure the realism of the image.

5 product design

There are a wide variety of full-color LED displays, such as indoor and outdoor energy-saving high-brightness, high-speed refreshing and portable products. The requirements for full-color LED display screens vary from industry to industry. Therefore, buyers are distinguishing between full-color LED displays and their choices. When a full-color LED display is used, it is necessary to collect its own requirements, and whether the manufacturer's full-color LED display products can meet their needs to the greatest extent.

6 production process

Full-color LED display belongs to the application industry. Unlike chip LED tube, which belongs to the upper and middle reaches industry, it needs a lot of advanced equipment and high-demand production environment. Therefore, the production process mainly examines the details of its production environment, equipment type and brand (do not think The more equipment, the better).

How to maintain full color LED display

The full-color LED display screen is like a traditional electronic product. In the process of use, not only the method needs to be paid attention, but also the display screen needs to be maintained and maintained, so that the full-color LED display screen has a longer life span.

(4) Full-color LED display requires stable power supply and good grounding protection. Do not use it under harsh natural conditions, especially during strong lightning.

(5) It is strictly forbidden to enter the water, iron powder and other easily conductive metal objects. The full-color LED display screen should be placed in a low-dust environment as much as possible. Large dust will affect the display of the full-color LED display, and excessive dust will cause damage to the circuit. If water enters for various reasons, please immediately turn off the power and contact the maintenance personnel until the display panel in the screen is dry before use.

(6) Switching sequence of full-color LED display: A: first turn on the control computer to enable normal operation and then turn on the full-color LED display screen; B: first turn off the full-color LED display, then turn off the computer.

(7) Do not stay in full white, full red, all green, all blue, etc. for a long time during playback, so as to avoid excessive current, excessive power supply, and damage to LED lights, affecting the service life of full-color LED displays. . Do not disassemble or splicing the screen at will!
