1. Display Effect
The display effect of a good LED display can be evaluated from seven dimensions, namely brightness, contrast, viewing angle, color gamut, refresh rate, resolution, and response time.
Brightness
Brightness is an indicator of how bright an image a display screen can produce. High brightness ensures that the display screen can remain clear and visible even in bright environments, making it suitable for outdoor or strong light environments.
Contrast
Contrast is the brightness difference between the brightest and darkest pixels that digital LED signage can display. High contrast provides deeper blacks and brighter whites, offering richer colors and more vivid images.
Viewing Angle
The viewing angle indicates the optimal angle for viewing display content with minimal color and brightness variation, ensuring great viewing effects from different positions.
Refresh Rate
The refresh rate of the LED digital signage, also known as “visual refresh rate” or “refresh frequency,” refers to how many times per second the screen refreshes the displayed image. It is measured in Hertz (Hz). A higher refresh rate enables more stable image display and less visual flicker.
Generally, there are three options of refresh rates for full-color LED displays, which include 960Hz, 1920Hz, and 3840Hz. They are known respectively as low, standard, and high refresh rates. Higher refresh rates ensure smoother dynamic visuals, which are crucial for video playback and gaming.
Resolution
Resolution refers to the amount and arrangement of pixels on the display screen. It is used to describe the display capability of the digital LED signage, that is, how many pixels the screen can display. Common resolutions include 720P, 1080P, 2K, 4K, etc.
Color Gamut
Color gamut denotes the range of colors the display can reproduce. A wider color gamut enhances color richness and accuracy.
Response Time
Response time measures how quickly each pixel responds to input signals, that is, the time taken for a pixel to change from dark to bright or vice versa. The shorter the response time, the faster the screen changes, which can reduce motion blur and ghosting during video playback.
2. Power Consumption
Power consumption is a critical consideration in digital LED signage selection. Although it is often overlooked, it directly impacts operational costs (electricity bills) and environmental footprint.
For instance, a P16 pixel pitch LDE display typically consumes between 30-300 watts per square meter, varying significantly with different manufacturing techniques. Typically, SMD displays have a higher power consumption, followed by DIP, with LOB displays being comparably more energy-efficient.
3. Durability and Reliability
The reliability of a display screen is tied to its durability and long-term stability, influenced by factors such as heat generation and dissipation, protection level, materials, and component lifespan.
Heating Generation and Dissipation
The high temperature caused by heat generation and poor heat dissipation can lead to reduced display performance, shortened lifespan, and safety hazards.
Protection Level
Protection level, typically indicated by an IP rating, describes the device’s ability to withstand dust and water. The IP rating consists of two digits (e.g., IPXX), with the first digit representing the dustproof rating and the second digit indicating the waterproof rating. The higher numbers suggest greater protection. Usually, the protection level for outdoor LED signage is IP65.
Material and Component Lifespan
The choice of the screen materials and components directly impacts the service life. High-quality materials reduce risks such as module cracking and water ingress, provide fire resistance and UV resistance, and maintain display performance by reducing yellowing. Meanwhile, reliable components enhance efficiency, minimize heat generation, and reduce maintenance costs.
4. Ease of Use
Ease of use refers to the convenience of user interaction with the digital LED signage. This is important throughout the entire process, including installation, software control during use, and after-sales maintenance.
Installation
LED screen display installation usually involves multiple steps. Simple installation solutions or straightforward hardware design can significantly save labor and time costs.
Software Control
Users interact with the display screen through software during use, and intuitive software operation can reduce training and usage costs.
After-sales Maintenance
Different maintenance and after-sales solutions can impact customer experience significantly. Straightforward and reliable maintenance solutions facilitate module replacement, reduce risks during high-altitude operations, and minimize repeated work.
