Answers To Questions About LED Display


As an important carrier of modern information display, LED displays have been widely used in commercial advertising, stage performances, stadiums, public places, and other fields.

As a person who buys an LED display for the first time, you may have many questions to answer. Let’s answer them one by one. Let’s take a look.

1. How do you choose the resolution of the appropriate LED display?

Choosing the appropriate LED display resolution is a process that requires a comprehensive consideration of multiple factors. The following are detailed analyses and suggestions:

First of all, we need to consider the application scenario of LED displays. Different places have different requirements for resolution.

For example, in conference rooms, exhibition halls, and other indoor places, the audience is closer to the display screen, so choosing a high-resolution LED display screen, such as P2.5 or P3, can better display details and colors and provide a clearer and more vivid visual experience.

In outdoor places such as squares and stadiums, the audience is far away. Choosing lower-resolution display screens such as P8 or P10 can reduce costs and energy consumption while ensuring the viewing effect.

Secondly, the viewing distance is also an important consideration. The closer the viewing distance, the higher the requirement for resolution. If the audience is within 5 meters of the display, the P2.5 or P3 resolution display is the right choice.

If the viewing distance is within 10 meters, the P4 or P5 resolution display can meet the demand. When the viewing distance is more than 20 meters, a P8 or P10 resolution display is more suitable.

This is because, with the increase in viewing distance, the recognition of pixels by the human eye decreases, so the resolution can be appropriately reduced to reduce costs.

In addition, the display content is also one of the key factors that determine the resolution. If you need to display high-definition videos, pictures, and other detailed content, then a high-resolution LED display is indispensable.

High resolution can ensure the clarity and fineness of images and videos and improve the visual experience of the audience. If you only display simple text, icons, and other content, then choosing a lower-resolution display can also achieve better results.

In addition to the above factors, it is also necessary to consider the connection and matching of the LED display with computers or other devices. If the LED display is mainly used to display images, videos, and other content on the computer, its resolution should be at least 1920*1080, which is commonly known as 2K resolution.

This can ensure that the resolution of the display screen is consistent with that of the computer output so as to present the clarity of the source signal and ensure the picture quality.

For some special application scenarios, such as a big data display system or 4K film source playback, higher resolution may be required, even more than 4K, or point-to-point display to meet specific display needs.

When selecting the LED display resolution, other technical indicators should also be considered, such as pixel spacing, brightness, contrast, refresh rate, etc.

The smaller the pixel spacing, the higher the definition of the display; brightness and contrast affect the performance of the display under different light conditions, and the refresh rate determines the dynamic display effect of the display.

The careful consideration of these technical indicators can ensure that you choose the most suitable LED display.

Finally, the cost and cost performance of the LED display need to be considered. High-resolution displays tend to be more expensive, so it is necessary to weigh the relationship between resolution and cost when choosing.

Under the premise of meeting the needs of users, try to choose cost-effective products.

2. How do you choose the brightness of the suitable LED display?

Choosing the right LED display brightness is a process that needs to consider multiple factors. Here are some suggestions to help you determine the appropriate brightness when choosing an LED display:

First of all, the environment of the display should be considered. The brightness of the LED display needs to be adjusted according to the ambient light.

In a bright environment, such as outdoors or indoors near the window, you need to choose a higher brightness display to ensure that the content is clearly visible.

In a darker environment, such as staying away from windows indoors or at night, a lower brightness may be more appropriate to avoid discomfort to the eyes of the audience.

Secondly, the viewing distance is also an important consideration. Generally speaking, the closer the audience is to the display screen, the higher the requirement for brightness.

Because when viewed at close range, the high-brightness display can ensure the clarity of images and text. However, if the distance is far away, excessive brightness may cause visual fatigue or glare.

In addition, the display’s content will also affect the choice of brightness. For example, if the display is mainly used to display dynamic videos or images, higher brightness can ensure the brightness and contrast of the content. For static text or pictures, the brightness requirements may be relatively low.

At the same time, it is also necessary to consider the visual comfort of the audience. Excessive brightness may make the audience feel dazzling, while too low brightness may cause the content to be unclear.

Therefore, when selecting the brightness of the LED display, it is necessary to find a balance point that can ensure not only the visibility of the content but also the visual comfort of the audience.

In addition, according to the brightness calculation formula of the LED display, the brightness is related to the luminous intensity, the surface area or three-dimensional angle of the light source, and the brightness adjustment ratio.

Therefore, when selecting the LED display, it is also necessary to consider its physical characteristics, driving current, and other factors to ensure accurate brightness values.

Finally, there may be differences in the brightness performance of LED displays of different brands and models.

It is recommended that you consult the product manual or the salesperson before purchasing to understand the brightness parameters and scope of application of the specific product.

3. What is the viewing angle of the LED display?

The viewing angle of the LED display means that the user can clearly observe all the content on the screen from different directions. Generally speaking, the perspective includes horizontal and vertical indicators.

Taking the horizontal viewing angle as an example, it means that the vertical normal of the LED display screen is subject to, and the display image can still be seen normally at a certain angle perpendicular to the left or right of the normal. Similarly, the vertical viewing angle is subject to the horizontal norm, indicating the visual range above and below the vertical.

Most LED display manufacturers will provide perspective information about their products. The viewing angle range of common LED displays is between horizontal 160°~170° and vertical 160°~170°, but the specific value may vary depending on the screen size, application scenario, and manufacturing process.

For example, some products may be marked with a horizontal/vertical viewing angle of 140°/140°, while the high-definition LED small spacing display may reach 160°/160°.

It should be noted that the viewing angle is not as large as possible. It needs to be selected according to the actual use scenario. In some specific application scenarios, excessive viewing angles may lead to image distortion or color deviation.

Therefore, when choosing an LED display, in addition to the viewing angle, it is also necessary to comprehensively consider the screen size, resolution, brightness, contrast, and other factors to meet the actual application needs.

4. Is the energy consumption of the LED display high?

The energy consumption of LED displays is a relatively complex topic that needs to be discussed in detail from many aspects.

First of all, it should be clear that the energy consumption of the LED display is not fixed but is affected by a variety of factors.

The first factor is the size and resolution of the display. Generally speaking, the larger the screen size and the higher the resolution, the more pixels it contains, which will naturally lead to an increase in energy consumption.

Because each pixel needs a certain amount of electricity to drive its luminescence. However, with the continuous progress of LED technology, today’s high-resolution and large-size displays have significantly improved energy consumption control.

Secondly, brightness is also a key factor affecting the energy consumption of LED displays. High brightness means that more power is needed to support it.

Therefore, outdoors or in a bright environment, the brightness of the display screen is usually increased to ensure the visual effect, which will naturally increase energy consumption.

However, most modern LED displays are equipped with an automatic brightness adjustment function, which can automatically adjust the brightness according to the strength of the ambient light so as to reduce energy consumption as much as possible while ensuring the visual effect.

In addition, the energy consumption of LED displays is also closely related to the use time and switching frequency. Long-term use and high-frequency switches will increase energy consumption. Therefore, when the display is not needed, its brightness should be turned off or reduced in time to save electricity.

In terms of driving mode, constant current driving is a relatively energy-saving way. It can stabilize the brightness of the display screen by controlling the size of the current and avoid the increase in energy consumption caused by excessive current.

At the same time, some advanced LED displays also use energy-saving control technologies, such as intelligent dimming, dynamic backlight, etc., which can effectively reduce the energy consumption of the display.

In addition, it is worth noting that although the energy consumption of LED displays is relatively high, its advantages, such as long service life and low maintenance cost, cannot be ignored. Moreover, with the progress of technology and the popularization of applications, the energy consumption problem of LED displays is gradually being solved.

For example, some new LED chips and materials have higher luminous efficiency and lower energy consumption, which provides the possibility to reduce the energy consumption of LED displays.

5. How durable is the LED display?

The durability of the display is closely related to the performance of its light source devices. The attenuation characteristics, waterproof steam penetration characteristics, and ultraviolet resistance of LED lamp beads have an important impact on their life.

If the performance evaluation of LED lamp beads fails, it may shorten the life of the display. Therefore, choosing high-quality LED lamp beads is the key to ensuring the durability of the display.

In addition, the quality of the supporting parts also affects the life of the display screen. Quality problems with components such as switching power supplies, circuit boards, plastic shells, connectors, etc., may lead to a decrease in the life of the display. Therefore, when buying a display screen, you need to pay attention to the quality and brand reputation of these parts.

The production process is also an important factor affecting the durability of the LED display. The high-quality three-proof treatment process can ensure that the display screen can maintain stable performance when temperature and humidity change. If the production process is not good, it may lead to the failure or performance of the display in a harsh environment.

The working environment also has a significant impact on the durability of the LED display. Indoor and outdoor environmental conditions are very different, so it is necessary to choose the appropriate display type and protection level according to the specific environment.

For example, the outdoor display screen needs to be waterproof, dustproof, sunscreen, and have other functions to cope with the impact of bad weather and the natural environment.

In addition, the use and maintenance method will also affect the durability of the LED display. Long-term continuous work, harsh use environments, lack of regular maintenance, etc., may shorten the life of the display. Therefore, rational use and regular maintenance of the display are important measures to ensure its durability.
