  • How to control the quality of your products?
    Our products have a 72-hour workshop aging test, and have passed the lamp life attenuation test, waterproof test, low and high temperature resistance test, leakage test, and high voltage test
  • How to choose high-quality chips?
    REISSDISPLAY uses a large gold wire chip, which is more stable than the products on the market. High brightness, long life, low attenuation rate, the brightness of the lamp chip will not decrease during long-term use
  • Does your factory support OEM?
    Yes. Our factory can OEM customized production. Can provide technical team support
  • What is the delivery time of your LED display?
    Our factory standard LED display manufacturing time is 10-15 working days, including 72 hours of aging and testing
  • What services can your company provide for the LED display project?
    Our factory has a professional LED display team, including construction engineers, structural engineers, product R&D engineers, and software engineers to provide the design of a complete set of solutions from production to installation
  • How to install the LED display for the first time?
    Our factory can provide professional engineers to serve you. Solve engineering installation design problems, and remotely solve software installation and debugging problems for you. Able to successfully complete all your after-sales problems
  • How to become your LED display distributor?
    We are looking for partners with LED display experience as local agents or distributors. For more information, please contact us
  • Why is it important to choose an LED display module circuit board?
    1. The circuit board design also affects the color and vividness, brightness and low grayscale of the entire LED display. Therefore, the design of the circuit board in our factory will be different from the products in the market.
    2.  The thickness of the copper sheet in the circuit board will also affect the conductivity and current of the entire LED display. Our factory adopts thickened design, so that the module circuit has better conductivity. Lower heat generation.
    3.  Our electronic component materials strictly follow international standards. Able to pass EMC certification. The failure of the module will be lower than the products on the market. Reduce maintenance costs.
  • Why can our products adapt to harsh environments such as climate temperature and humidity in different regions?
    Reasons why the failures are very low in different regions and different ambient temperatures:
    1. Our LED display module materials can work normally in environments with a low temperature resistance of -45 degrees and a high temperature resistance of 85 degrees.
    2. The standards of our power supply are customized according to different regions.
    3. Our module interfaces are all customized with gold-plated materials. The data cable and power cable are customized according to international standards.
  • What is grey level ?
    Grey level: A calibrated sequence of grey tones, ranging from black to white. In remote sensing, electromagnetic radiation falling on a photosensitive receiver generates an electrical current proportional to the intensity of the radiation. The receiver is usually tuned to specific wavelength bands and the signal from each receiver is amplified and its intensity classified into different levels, usually 0 (black) to 256. These are the digital numbers of each of the pixel units that together make up a remotely sensed frame. Grey level: A calibrated sequence of grey tones, ranging from black to white.

These are the digital numbers of each of the pixel units that together make up a remotely sensed frame.In the multispectral scanning system, the numbers are classified into gray bands, up to 22bit (HDR).
  • What is LED dispaly ？
    LED display is composed of the array of LED devices used to display text, text, graphics, images, animation, market, as well as a variety of television, video, live events and the like.  LED display screen is a new type of information and communication media; It is a collection of electronic, optical, communication, computer, network, structure, civil engineering and other disciplines.LED display is kind of customized products due to different specifications and sizes.
  • What the LED Colors & Intensities mean ?
    The color and brightness emitted by an LED are determined by the chemical composition and construction. Single-color (monochrome) displays are made up of one color of LEDs, whereas full-color displays contain LEDs that emit red, green and blue light. The color efficiency of the human eye has different sensitivity to different colors, and therefore perceives the brightness of each color differently.The number of LEDs alone does not determine display brightness. The design, quality, brightness, lens and viewing angle of the LEDs, as well as the drive method and contrast of the module, determine the overall brightness of a display. In fact, using more LED’s per unit area creates more hear and therefore requires more cooling.
  • What are Pixel Pitch, Pixel Density, and Pixel Configuration ?
    Pixel Pitch is the distance between neighboring pixels which calculated by mm.Pixel Density is the quantity of pixels per square meter.
    Pixel Configuration is the description of the consistence of a pixel. For example, we use 1 red lamp, 1 green lamp, 1 blue lamp to compose a pixel, the pixel configuration is 1R1G1B or SMD 3 in 1.
  • LED Display’s lifetime ?
    The operational lifetime of an LED Display is determined by the lifetime of the LEDs. LED Manufacturers estimate the LED lifetime to be 100,000 hours under certain operating conditions. The lifetime is decided when the brightness has decreased to 50% of original brightness.Three primary factors determine LED lifetime:Manufacturing process of the LEDDriving (powering) method of the LEDTemperatures present at the LED die during operationLED thermal management is vitally important to maintaining LED lifetime. Increasing the power through an LED increases brightness but reduces its lifetime due to increased heat generation. Increased exposure to higher temperature also shortens the lifetime. LED thermal management can only be done through the LED lead frame by conducting the heat to a Printed Circuit Board (PCB) and by allowing airflow to cool the LED lead frame.LED Display components must be designed to handle a wide range of outdoor environmental factors, such as temperature and humidity. All components must be coated to protect from possible corrosion.
  • The explanation of Ingress Protection (e.g.IP65)
    Ingress Protection (IP) is a European rating that describes the degree of protection provided by an enclosure of electrical equipment. The rating system consists of the letters IP followed by two numbers:
    The first number indicates the degree of protection against solid foreign object ingress.
    The second number indicates the degree of protection against liquid ingress.According to this system an IP65 enclosure will not allow the ingress of dust and is protected against jets of water from any direction. IP65 enclosures are ideal therefore for use in wet and wash-down environments for example food preparation areas.
