LED displays have become an increasingly popular way for businesses to engage with customers, showcase products, and communicate important information. However, with so many different options available, it can be challenging to determine the quality of an LED display and choose the right one for your business needs. 

In this article, we will shed light on how to determine the quality of an LED screen display for your business. From assessing your business needs to understanding image quality and durability, we will provide a comprehensive guide to help you make an informed decision when selecting an LED display.


Determining Your Business Needs

LED displays have a wide range of business applications that can benefit different industries and settings. Here are some examples:


Advertising and Marketing

LED displays are often used to advertise products or services in retail settings, at trade shows or exhibitions, and in outdoor advertising.

When it comes to advertising and marketing, LED displays come in a wide variety of sizes and resolutions to suit different needs and settings. For indoor advertising in smaller retail stores, a 32-inch or 40-inch LED display with a resolution of at least 1080p is typically sufficient. However, larger displays with higher resolutions may be necessary for larger retail spaces, shopping malls, and exhibitions.

For outdoor advertising, larger LED displays with higher brightness and weather-resistant capabilities are recommended. A common size for outdoor LED billboards is 14 feet by 48 feet, although smaller sizes such as 10 feet by 30 feet or 10 feet by 20 feet can also be effective. These displays typically have a resolution of at least 720p or higher.

In terms of image quality, a higher resolution and pixel density will generally result in a better picture. For advertising and marketing, it is recommended to use LED displays with a minimum resolution of 1080p for indoor displays and 720p for outdoor displays. Additionally, displays with a high refresh rate and contrast ratio can enhance the visual impact of the content being displayed.




LED displays are used in entertainment venues such as cinemas, concert halls, and sports stadiums to display high-quality images and videos, as well as for live event streaming and interactive displays.

The recommended size of an LED screen for entertainment venues varies depending on the specific application and viewing distance. For example, a cinema screen typically requires a larger screen size than a sports stadium display due to the different viewing distances involved.

A typical screen size applicable for cinemas ranges from 30 feet to 100 feet in width, while for a sports stadium display, a screen size of 16 feet to 25 feet in height is recommended.

And for halls, the recommended screen size is dependent on the venue size and layout, but typically a screen size of at least 16 feet in height is recommended to provide a clear view of the stage for all attendees.

Interactive displays such as those used in museums or art galleries may require smaller screens, ranging from 10 inches to 65 inches in size, depending on the intended use and the viewing distance.


Important Technical specifications of an LED screen

The technical specifications of an LED screen are important to businesses because they determine the quality and effectiveness of the display. 

Brightness and viewing angle

To ensure the best performance of LED display screens, brightness, and viewing angle are important factors to consider. For indoor full-color displays, it is recommended to have a brightness level above 800cd/m, while outdoor full-color displays should have a brightness level above 1500cd/m. This ensures that the images on the screen are clear and not fuzzy due to low brightness. The quality of the LED die used in the display screen greatly affects the brightness level.

Moreover, a wider viewing angle is preferred to cater to a larger audience. The packaging method of the LED dies determines the magnitude of the viewing angle. Therefore, it is recommended to choose a display screen with a wider viewing angle to ensure that the display is visible to as many people as possible.


Having a flat LED display screen is crucial for businesses as it ensures that the image displayed is not distorted and can be viewed clearly from all angles. To achieve this, businesses should ensure that they invest in high-quality LED screens with flat surfaces. It is also recommended that businesses work with reputable manufacturers or suppliers that can guarantee the flatness of their LED screens. Additionally, regular maintenance and calibration of the LED screens can help to maintain their flatness and ensure the best possible image quality.

White balance

White balance is a critical factor in determining the color accuracy of an LED screen display. Inaccurate white balance can result in distorted colors, making the display less effective in conveying information or attracting customers. To ensure proper white balance, businesses should consider investing in LED screens with high-quality control systems that can accurately adjust the color temperature and balance of the display. It is also essential to select LED screens with high-quality dies that can accurately restore colors and maintain consistent white balance.

To maintain accurate white balance, businesses should also regularly calibrate their LED screens to ensure that they are functioning correctly. Calibration involves adjusting the display’s settings to match a specific color standard, such as the industry-standard Rec. 709. Regular calibration ensures that the LED screen remains accurate and effective in conveying information or advertising products or services. It is recommended to have a professional calibration at least once a year, or more frequently depending on the usage of the display screen.

Color restoration

Color restoration is a crucial factor when it comes to selecting the right LED display screen for your business. It refers to the ability of the screen to accurately display colors that match the source material. If the colors on the screen don’t match the source, the image can appear distorted or unrealistic.

To ensure that the colors are accurately restored, it is recommended to select an LED display screen with a high color gamut. The color gamut refers to the range of colors that the screen can display, and a wider color gamut means that the screen can display more colors.

It is also important to consider the color temperature of the screen. The color temperature is the degree of warmth or coolness of the white light that the screen emits. For indoor displays, a color temperature of around 6500K is recommended, while for outdoor displays, a color temperature of around 7500K is recommended.

Refresh rate

Refresh rate is a key specification to consider when selecting an LED display screen. It is a measure of the number of times the display information is fully updated per second, and it is typically measured in Hz. A low refresh rate can cause images to appear dithered and may result in scanning lines appearing on cameras when filming the screen.

To ensure a smooth viewing experience for the human eye, it is recommended that the refresh rate is above 300Hz. This means that as long as the refresh rate is above 300Hz, people will not see dithering on the screen with the naked eye. For shooting purposes, the refresh rate should be at least above 600Hz to prevent scanning lines from appearing in the footage. Different cameras may have different requirements for the refresh rate based on their settings.

In addition to improving the viewing experience, a high refresh rate can also improve the brightness and color fidelity of the display screen. Digital cameras can detect the difference between a high and low refresh rate, with high refresh rate screens resulting in sharper images without snow spots or scanning lines. This is particularly important for leased screens and those used for television rays.

Power consumption

Power consumption per square is an important technical specification to consider when selecting an LED display screen. This parameter measures the amount of power consumed by the display screen per square meter of its area, and its unit is the watt. It’s essential to know the power consumption to determine the cost of electricity and avoid exceeding the electrical capacity of the venue where the screen will be used.

For instance, if the functional consumption of a one-square-meter LED display screen is 300 watts, the display screen consumes 300 watts of electricity per hour per square meter. Typically, there are two indicators for the power consumption of LED display screens: maximal power consumption and functional power consumption.


In the business world, LED screens with high contrast are important for creating engaging and eye-catching advertisements, product displays, and presentations. For example, a clothing store might use an LED screen to showcase a new clothing line with bright, vivid colors and sharp contrast to attract customers. A car dealership could use an LED screen to display high-quality images and videos of their cars with crisp, clear contrast to give customers a closer look at the features and design.

High contrast is also important in the entertainment industry, such as for concerts or live performances, where LED screens are used as a backdrop. The higher the contrast, the more vibrant and immersive the visuals can be, adding to the overall experience for the audience.

To ensure high contrast, it is recommended to choose LED screens with high-quality LED chips, which will provide better color reproduction and contrast. Additionally, proper calibration of the screen is important to optimize contrast levels and ensure the best possible visual experience.

Color Temperature

Color temperature refers to the measurement of the color of white light emitted by a display screen. It is important because it affects the overall color accuracy and consistency of the displayed images. When the color temperature of a display screen is not properly balanced, the images can appear distorted or different from the source.

In business, color temperature is particularly important for LED screens used for advertising or promotional purposes. For example, a company may use an LED screen to display its product images or videos at a trade show or exhibition. If the color temperature of the screen is not properly adjusted, the colors of the products may appear different from their actual appearance, which can negatively impact the customer’s perception of the product.

To ensure the color accuracy and consistency of the displayed images, it is recommended to adjust the color temperature of the LED screen to a range of 6500K to 8000K for direct viewing by human eyes. However, if the screen will be used for television broadcast, it should be adjusted to around 5500K to ensure that the recorded and broadcasted images are true to life.

Check to see if there is a color block displayed anywhere on the LED Screen

Color blocks can be a significant issue in LED display screens, as they create an uneven and unprofessional appearance that can distract viewers from the intended message. The term “color block” refers to an obvious difference in color between adjacent modules on the screen.

The presence of color blocks is often related to technical factors such as the quality of the control system, the gray level, and the scanning frequency. A poor control system can result in inaccurate color rendering, while a low gray level means that there are fewer steps in the transition from black to white, which can make color transitions more noticeable. Similarly, a low scanning frequency can cause color blocks to appear more prominently, especially in fast-moving images.

To ensure the best possible display quality, it is recommended that LED display screens have a high-quality control system, a high gray level, and a high scanning frequency. For example, a gray level of 14 bits or higher can help minimize color blocks, while a scanning frequency of at least 1920 Hz can provide smooth, seamless transitions between colors.

Wavelength establishes the color’s purity and consistency

Wavelength is an important factor that determines whether the color of an LED screen is pure and consistent. To ensure accuracy, professional equipment is usually required, but there is a simple way to confirm the wavelength accuracy without such equipment. 

Firstly, you can make the whole screen white and check if it is pure white without any other colors mixed in. Any deviation from pure white indicates problems with the materials or the quality control of the production process. 

Secondly, you can check the whole screen with red, green, and blue colors respectively. If the colors look darker or lighter than they’re supposed to be, it proves that the wavelength deviates. If a certain color is inconsistent, it indicates that the wavelength difference is too large.

High-quality display screens have a wave difference that is controlled within specific ranges. For example, the wave difference should be controlled at 3nm for green and blue, and at 5nm for the red of high-quality display screens within the range of central wavelength. This ensures that the colors on the screen are pure and consistent, which is crucial for businesses that rely on high-quality visual displays, such as advertising or entertainment industries.



The cost of a quality LED screen display for a business can vary greatly depending on factors such as size, resolution, and features. Generally, a high-quality LED screen display can range from several thousand dollars to tens of thousands of dollars.

For example, a small LED screen display with a resolution of 1080p and basic features such as brightness and contrast control can cost around $2,000 to $5,000. A larger LED screen display with a higher resolution of 4K and additional features such as remote control and video wall capabilities can cost upwards of $10,000 to $20,000.

The cost also depends on the manufacturer and the specific model. Some of the top manufacturers of LED screen displays include Samsung, LG, and Sony, with prices varying depending on the size and features of the display.

It is important to note that while a high-quality LED screen display can be a significant investment, it can also provide long-term benefits for a business in terms of advertising, branding, and attracting customers. Additionally, a well-maintained LED screen display can have a longer lifespan and require less maintenance and replacement costs in the long run.



In conclusion, investing in a high-quality LED screen display can have a significant impact on your business, from attracting customers to improving engagement and increasing sales. However, it’s important to carefully consider factors such as pixel pitch, brightness, contrast, color temperature, color block, wavelength accuracy, and power consumption when choosing a display. 

As we have seen, prices can vary greatly depending on the size and specifications of the display, with a range of $1,000 to $10,000 per square meter for high-quality screens. It’s important to find a balance between cost and quality to ensure that you get the most value for your investment. By taking the time to research and choose the right LED screen display for your business, you can create an impressive and effective visual display that sets you apart from the competition.
