Unconventional LED Screen - LED Screen Parts


With the development trend of micro-pitch displays, 4-layer and 6-layer boards have been adopted. Printed circuit boards will use micro-via and buried-hole designs, printed circuit pattern wires will be fine, and micro-holes will be narrowed. The mechanical drilling technology can no longer meet the requirements, and the rapidly developing laser drilling technology will meet the fine hole processing.

How Much Influence Does Heat Dissipation Have On High-Brightness LEDs


With global energy shortage and environmental pollution, LED display screens have a wide application space due to their energy saving and environmental protection characteristics. The application of LED lighting products in the lighting field is attracting the attention of the world. Generally speaking, whether the LED lamp works stably and with good quality is very important for the heat dissipation of the lamp body itself.

Ordinary Graphics Processing Technology LED Screen Parts

We know that the point-to-point image display effect is the best. After reducing the image, if only ordinary graphics processing technology or general FPGA graphics processing algorithm is used, the edges of the image will appear jagged, and even pixels will be missing. The brightness will also decrease. High-end image processing chips or FPGA systems that use complex graphics processing algorithms will maximize the display effect of reduced images.

LED Transparent Screen Selection Reference Analysis For Shopping Mall - Technology News Shopping LED parts

With the development of the economy, it is common [...]

With the development of the economy, it is common to install LED displays in shopping malls. LED power supply in shopping malls are generally used for brand promotion and product promotion, creating a good shopping atmosphere and mobilizing the atmosphere. The emergence of a new type of advertising media tool, the transparent LED display, provides more choices for shopping malls: transparent, cool, stylish, and full of technology.

Generally speaking, the LED display screen in conventional shopping malls weighs more than 30kg / ㎡, which requires high load-bearing capacity of the original building structure. It requires a large-scale steel frame structure during construction, which is time-consuming and labor-intensive. Bright is a dark piece, affecting the beautiful appearance of the mall building, blocking sunlight and sight, and affecting daylighting.

The transparent LED display is thin and beautiful, and has relatively low requirements for building load bearing. When it is not lit, it does not affect the aesthetic appearance of the building; high permeability ensures the lighting requirements of lighting structures such as floors between malls, glass facades, windows, etc. At the same time, it has good heat dissipation function and is easy to install and maintain. When playing advertisements, when designing the advertisement content screen, remove the unnecessary background color and replace it with black. You only need to display the expressed content, and the appropriate part does not emit light during playback, which is a transparent effect. This playback method is extremely Greatly reduce light pollution, can also reduce energy consumption LED Display, can achieve more than 30% energy saving than conventional LED display.

According to the characteristics of the mall and the actual needs of customers, the following is a reference for the selection of LED transparent screens in malls given by Orida:

  • Indoor use, protection grade IP43, no waterproof required, high protection grade can be customized for special places;     
  • The fixed installation method does not affect the original wall structure;   
  • High permeability, does not affect the shielding effect;
  • Consistent with the image of the mall center, remote control and operation can be realized.
  • The viewing distance is short, the display is required to be clear, and the pixel pitch is within 5mm.
      

The advertising content on the LED transparent screen can be changed at any time, displaying different advertisements around the clock;

High-efficiency optical fiber LED transmission system is adopted to effectively reduce the signal delay caused by long transmission distance and ensure the consistency of picture playback.

Shopping mall LED transparent screens are generally personalized according to the shopping mall environment and are coordinated with the installation environment. The front-maintained LED full-color transparent screens are selected for various modeling designs. The products with small LED cabinet sizes and ultra-thin, Surface-mount LED transparent screen with a dot pitch of about 10mm.

Evaluation of Micro-Pitch LED Show Technology


The display with density above P2 generally uses 1515, 2020, and 3528 lights, and the NovaPro UHD Jr shape adopts J or L package. Side welding pins, the welding area will be reflective, the ink effect is poor, it is necessary to add a mask to improve the contrast. The density is further increased, and the L or J package cannot meet the application requirements. A QFN package must be used. The characteristics of this process are no lateral welding pins and no reflection in the welding area, which makes the color rendering effect very good.

Relationship Between Chip Size And Heat Dissipation


The most direct way to increase the brightness of a power LED display video processor is to increase the input power, and in order to prevent saturation of the active layer, the size of the pn junction must be increased accordingly; increasing the input power will inevitably increase the junction temperature and thus the quantum efficiency.

LED Video Processor | LED Screen Parts


This design not only saves the packaging cost, but also improves the reliability of the product. It has been widely used in outdoor LED display products. The SAM (Scanning AcousTIc Microscope) was used to test the airtightness of the LED bracket with the folded structure design and the normal bracket. As a result, it can be found that the product with the bent structure design has better airtightness. View More >> LED tools

Multi Function Stadium Requirements For LED Displays


The multifunctional modern gymnasium can be used not only to hold various sports competitions, but also to hold various large-scale cultural events and rallies. Therefore, the requirements for the display screen can be summarized as rich, diverse, and real-time. Sports competitions, cultural performances, and large-scale events held in the stadium can be broadcast live through the electronic display, and have special effects such as panoramas, close-ups, slow motion, flash action, drag images, nostalgic movies and so on.

Perchase Best LED Module | LED Screen Parts


The safe use current of LED lamps is generally 20 milliamps. Above this value, although the brightness will increase a little, the color attenuation will significantly accelerate. Therefore, when purchasing an assembled LED module, you must test its output current value. Brightness below 20 milliamps is not enough, and more than 22 milliamps affects LED life and accelerates color decay. Read More >> Indoor LED Module

Purchase Best Qualified LED Parts


Purchase qualified LED single lamp pellets produced by regular manufacturers (the quality parameter description provided by the manufacturer is required), and make the module yourself. Do not try to buy a single LED light bulb or a manufactured module in the electronic display market. If you need to buy a module, you should see how many resistors are installed on the module. It is best not to use a module with one resistor installed. Read More >> LED Control Card
