This document outlines methods and precautions for selecting indoor LED displays. When choosing an indoor LED display, first determine your specific needs, such as intended use, pixel pitch, and main functions. LED display manufacturers will then provide reasonable suggestions and corresponding solutions based on your requirements. Below are some methods summarized by manufacturers for your reference:
How to choose an LED display?
1. Determine whether your LED display will be used indoors or outdoors. If indoors, it's an indoor LED display; if outdoors, it's an outdoor LED display.
2. Determine whether you need a monochrome, bi-color, or full-color display. Full-color means a full-color LED display.
3. Determine the pixel pitch, commonly referred to as P2.5, P6, P8, P10, etc. How to determine the pixel pitch? Here's a formula: P = L / 1700, where P is the pixel pitch in mm, and L is the closest viewing distance in mm; that is, a P1.6 LED display is suitable for viewing from a distance of 2.7m or more.
What aspects should be considered when purchasing an indoor LED display?
I. Packaging form. Indoor LED displays have several LED surface forms: single lamp, sub-surface mount, three-in-one surface mount, and three-in-one surface mount, each with a different appearance. The advantage of surface mount packaging is a large viewing angle and good light emission consistency. It is easy to automate welding and processing, and is the mainstream product for full-color LED screens, but the price is currently relatively high; single lamps have a slightly smaller viewing angle, slightly higher brightness, and lower price. Sub-surface mount is actually a type of single lamp. Single lamps and sub-surface mount are relatively inexpensive and are transitional products.
II. Density. Due to the large heat generation of indoor full-color LED chips and the high density of control circuits, the pixel density of commercially available full-color screens cannot yet be very high.
III. Real pixels and virtual pixels. Similar to outdoor full-color screens, the number of pixels in indoor full-color screens is also divided into real pixels and virtual pixels.
IV. LED chip. A good LED chip ensures the quality of the LED.
V. Driving method. The driving method of indoor full-color LED displays is constant current driving, using dynamic scanning (mainly 1/4, 1/8, etc. scanning methods). With the same LED chip, 1/4 scan displays require more circuitry and offer higher brightness.
In summary: When choosing an indoor LED display, the correct approach is to select a product that suits your needs, rather than blindly choosing based on price. Choosing the right product will allow you to better utilize the LED display and generate more benefits. This concludes our discussion on how to choose an LED display.
