Common Issues in the Design Plan of LED Outdoor Display Screens

　　LED outdoor display screens are very common in daily life, and their design plans are also very important. Do you know the major considerations for customizing LED outdoor display screens? Below, the editor will explain them to you.

　　LED outdoor display screens are favored by customers for their clear interface, durability, energy efficiency, and environmental protection features. When manufacturing the product, certain requirements must be observed to produce a good product.

　　In heat dissipation design, the heat dissipation of the PCB board and the natural ventilation design of the casing must be set in a timely manner. Excessive machine temperature will affect the performance reliability and service life of the LED outdoor display screen.

　　In mixed light design, the lamp insertion diagram is created according to the discrete variable law, ensuring consistent brightness of the display and avoiding chromatic inconsistency.

　　When designing the optocoupler circuit, attention must be paid to the arrangement of the driver IC on the circuit board. The transmission distance on the PCB affects the overall brightness of the display. Therefore, it is common for the edges to be brighter than the center.

　　The vertical angle of the lamp determines the chromaticity, which requires high manufacturing processes to ensure all LEDs are vertical on the PCB board while maintaining overall chromatic consistency.

　　The main cause of LED outdoor display screen crashes is internal component cold solder joints. To improve this issue, strict processes and product quality inspections are necessary. Products should be tested before market release, with anti-static operations, control of wave soldering temperature, and oven time—all important considerations during design.

　　Where do the price differences of outdoor LED display screens lie?

　　1. In terms of color, LED displays can be divided into single primary color, dual primary color, and full-color LED displays. Currently, full-color LED displays are more expensive than single or dual primary color ones.

　　2. In terms of usage scenarios, they can be divided into indoor, outdoor, and semi-outdoor. Each type of LED display has different prices. Currently, popular indoor small-pitch displays are much more expensive than outdoor or semi-outdoor ones due to their technology and cost.

　　3. Different raw materials can be divided into imported and domestic materials. Taking the light-emitting chip as an example, whether imported or domestic, each has its own advantages and disadvantages. Imported chips from the US and Japan have always controlled key technologies and are naturally more expensive. Conversely, domestic chips are cheaper. If the LED display is to be used in important venues, imported materials are more suitable; otherwise, domestic materials offer better cost performance.

　　4. Screen total area size: Outdoor LED displays generally have a much larger total screen area than indoor LED displays. Outdoor LED displays are usually tens of square meters to thousands of square meters, while indoor LED displays are limited by indoor space to only tens of square meters. Therefore, when calculating by total area, the final price difference can be quite large.
