With the advent of the information age, the use of LED screens is becoming more and more widespread. When we need to use the LED screen, the specific need for a large size of the LED screen is the first thing we need to be clear, the LED screen is too big will squeeze the space, too small will lead to viewing is not clear. So, how to confirm the size of the LED screen for us is how much? Let’s take a look.
Why do we need to clarify the LED screen size
Application of environment and function
In different environments, our requirements for LED screen size is also subject to change. Imagine, when we are in the outdoors, around the traffic, people coming and going, very lively; at this time, we want to set up a billboard to let the crowd see, and memorable, then, by setting up a huge LED display to the pedestrians to bring enough shock.
When we just have a meeting indoors, then the use of indoor LED screens can be clear enough to focus the eye without taking up too much space.
Cost Calculation
Cost-effective is never a word that can not be ignored, the same configuration of the LED screen, the larger the size, the more expensive. If we know exactly what size LED screen we need, we can achieve the visual effect we want and avoid paying extra.
Technical compatibility
There are some standard-sized LED screen modules on the market, using these standard-sized modules to assemble, of course, means that it is easier and faster, so that we can more skillfully grasp the effect that the LED display is expected to produce, to maximize the restoration.
Factors that may affect the choice of LED screen size
In addition to these considerations are closely related to our selection of LED screen size, there are other factors that we can not be ignored, if we ignore these factors, may lead to our selection of the screen size and site viewing needs do not match, affecting our subsequent viewing effect.
Resolution and pixel pitch
Pixel pitch refers to the distance between the center of the two LED lamp beads, the larger the pixel pitch, the greater the distance between the appropriate viewing, and generally the screen size needs to be larger.
Resolution determines the clarity of a screen image, the larger the LED screen size requires a higher resolution.
Viewing distance
The optimal viewing distance of the LED screen is usually a range of values, we need to envision the audience’s viewing distance to confirm the appropriate LED screen size.
Generally, the larger the LED screen size and the larger the pixel pitch, the further away the optimal viewing distance will be.
Project Budget
When we are clear about how much resolution we need the LED screen to have for the broadcast effect, the larger the LED screen size picked, the more expensive it will be.
For example: the same 2k resolution LED screen, 10 square meters of LED screen than 6 square meters of LED screen price; and when we need a 10 square meters of LED screen, 4k resolution than 2k resolution LED screen price.
Therefore, in combination with the budget to consider the situation, we can properly sacrifice some screen size or resolution to get a suitable LED screen.
Installation environment and space limitation
Installation environment in the outdoor, usually means that the viewing distance is farther, then you need a larger size and pixel pitch to achieve a better viewing effect. Installation environment in indoor, usually means that the viewing distance is closer, we need to take into account the space limitations, and high resolution, clear viewing.
Impact of screen aspect ratio on content display
LED screen aspect ratio affects the proportion of the playback screen, selecting the screen size, but also pay attention to the screen aspect ratio is appropriate, if the screen aspect ratio compared to the commonly used on the market screen aspect ratio difference is large, you will need to use the video player to adjust the screen in order to display the best picture effect.
In addition, choose the right LED screen aspect ratio and the environment more compatible, the appearance will be more beautiful.
Play content and purpose of use
LED screen is used in different ways, play different content, which means that the size of the different needs.
If it is used for outdoor advertising video, of course, is the larger size is powerful enough to attract people’s attention.
If it is used for indoor exhibition video, usually close viewing, the size does not need to be too large, clear can be.
Visual Impact
The larger the size, the stronger the visual impact. When people face an oversized LED screen, the dynamic video presentation will always make them exclaim.
How to calculate the LED screen size?
Different types and specifications of LED screen size will be calculated differently, which usually depends on the shape of the LED screen we want to calculate, as well as some of our known conditions of the LED screen.
According to viewing distance
When we know the pixel pitch and the average viewing distance of the audience, according to the appropriate viewing distance of 1 square meters of LED screen for the pixel pitch of 1 ~ 1.5 times to calculate the size of the screen size.
Formula: screen area = viewing distance ÷ pixel pitch ÷ (1 ~ 1.5)
For example: the average viewing distance of the audience for 45m, the use of pixel pitch p10 LED screen;
- According to 1 times to calculate: screen area = 45 ÷ 10 ÷ 1 = 4.5 square meters
- According to 1.5 times to calculate: screen area = 45 ÷ 10 ÷ 1.5 = 3 square meters
Then you can get, when the average viewing distance of the audience for 45m, with p10 LED screen, the appropriate size of the screen area of 3 square meters ~ 4.5 square meters.
According to width and height (standard rectangle method)
When we face the standard rectangular screen, can directly measure the width as well as height, then we can directly use the height × width to get the area of the LED screen.
Formula: screen area = width × height
For example: it is known that our display is 6m wide and 4m high, then its area is calculated as 4m × 6m = 24 square meters.
According to cabinet size and number of cabinets
When our LED screen is assembled using a box, then in the case of known cabinet size and the number of cabinets, you can calculate the LED screen area.
Formula: screen area = cabinet width × cabinet height × number of cabinets
For example: it is known that we use the box is 1m height and 1m width, assembly of LED screen using a total number of 200, then its area is calculated as 1m × 1m × 200 = 200 square meters
According to the pixel pitch and the pixels
When we know the pixel pitch of the LED screen, and the pixels in the horizontal and vertical directions, we can also calculate the size of the LED screen.
Formula: Width = Pixel Pitch x Number of Horizontal Pixels
Height = pixel pitch x number of vertical pixels
Screen area = width x height
For example: the specification is P10 (10mm pixel pitch), the number of pixels is 1920 (vertical) and 1080 (horizontal)
Calculation of screen area:
- Width = 1920 x 10mm = 19200mm = 19.2m
- Height = 1080 x 10mm = 10800mm = 10.8m
- Screen area = 19.2m × 10.8m = 207.36 square meters
According to LED Screen Aspect Ratio
Formula: Aspect Ratio = Screen Width ÷ Screen Height
4:3 LED Screen Size Ratio
The traditional LED screen size ratio is 4:3. Although it is less common nowadays, some special scenarios still use this aspect ratio.
16:9 LED Screen Size Ratio
The most widely used screen size ratio in the movie and television industry today is 16:9, which is more in line with people’s viewing habits.
Customized LED Screen Sizes
In the LED screen application more and more widely today, we use the LED screen habits are no longer limited to several aspect ratios, more or according to the use of occasions to freely customize the size of the LED screen, LED screen module assembly and cabinet assembly is very good to meet our needs and ideas about the size.
How to choose the right LED screen?
Check the budget
The size of the LED screen and related specifications are associated with the cost, so we need to consider the budget to meet the demand as much as possible. If the budget and space are sufficient, we can of course pick the top size and resolution configuration; if the budget is limited, we can increase the pixel pitch or reduce the size.
Consider the size of the LED display provided by the supplier
Some module sizes commonly used in the market, JYLED’s production batch is larger, and the profit of a single LED screen module will be reduced. If a custom module is chosen, there may also be a new mold involved in production, which can be more expensive.
Generally speaking, using a supplier’s existing LED module sizes for assembly will be more cost effective than customized sizes. If you still have questions about this, you can send a form to contact us, we will provide you with more professional and detailed solutions.
Consider various factors
Measure the expected installation area
Usually we need to measure the installation area in advance to ensure that the size of the LED screen to be installed is within the space. In addition, we can combine the expected installation space and the expected installation size to consider, in order to more closely match the installation environment, sometimes can be appropriate to increase or reduce the size of the LED screen, so that the LED screen and the environment as a whole more harmonious and beautiful.
assessment of environmental lighting conditions
LED screen installation environment itself is different brightness, the brightness of the LED screen requirements will be different. In the indoor, low environmental brightness, the brightness of the LED screen requirements are generally between 500 ~ 800; in the outdoor, high environmental brightness, the brightness of the LED screen requirements are generally between 4000 ~ 5500.
Of course, these are just reference values in general, the specific demand for brightness values need to be determined according to the specific installation environment.
determine the use of space
Typically, the larger the event venue, the more the number of viewers, the larger the screen size required, the larger the appropriate pixel pitch.
Determine the type of installation and flexibility according to the use
According to the use of LED screen we can plan the installation of LED screen is a short-term installation or long-term installation, such as stage activities show, competition activities show belongs to the short-term installation, should choose the LED screen rental series cabinet to assemble, rental series cabinet volume is small, light weight, assembly flexibility is higher, installation and disassembly will be more convenient.
For example, the skyscraper giant advertising display board, shopping mall display board, etc., belongs to the long-term installation, the use of fixed installation, only need to pay the labor cost of an installation.
Choose the configuration according to the demand
Resolution directly determines the degree of clarity and vividness of the screen, pixel pitch and viewing distance are closely related. We need to match the appropriate configuration of the LED screen according to the needs of the site.
Maintenance and repair
We often based on the installation and removal of LED modules to distinguish the maintenance mode, in general, the larger the size of the installed LED screen, the higher the relative maintenance costs.
Conclusion
When selecting the ideal size of LED screen, we need to consider the resolution, pixel pitch and viewing distance of the LED screen in conjunction with the size of the venue and the expected audience, and then use these factors to comprehensively calculate the appropriate LED screen size.
More importantly, the screen size and other relevant configurations should be selected to fit our project budget. If you still have questions about the selection of LED screen, you can contact JYLED consulting detailed program and quotation.
