When buying LED display, we need to calculating the area of LED display, so that the LED display supplier can give us an accurate quotation.
For customers who intend to buy LED screens, how to report the area to the LED display manufacturer is a headache.
So, what factors should we consider when calculating the area of the LED display?
In the calculation of the display area, we need to consider the following points:
- The relationship between the effective viewing distance and the actual site size;
- Pixel size and resolution;
- Area estimation based on units;
- Screen mechanical installation and maintenance operation space;
- The influence of screen inclination on distance.
Knowing these points, how do we calculating the area of the LED display?
Here’s a general formula:
Screen area = screen length * screen height
Screen length = length of the selected unit board * number of unit boards Screen height
Number of unit boards Screen height = height of the selected unit board * number of unit boards.
After knowing how to calculate the area of LED, some customers will be more concerned about the price.
Unlike LCD, LED can be sold directly as a whole screen, and the price of LED will vary greatly according to different accessories.
The price of LED display screens is closely related to the basic configuration of LED screens,
including LED lamp beads, chips, cabinet materials, etc., and even has a lot to do with the processing technology of direct insertion, surface mount or COB.
LED displays can be divided into outdoor, indoor, monochrome, and full-color.
The price of each LED screen is different, the resolution is different, the lamp bead specifications are different, and the price difference is also very large.
For the price, we can consider the following three points:
Specification Material
The material quality of the LED display is also critical. The quality of materials used in the production of indoor LED full-color displays mainly refers to the LED lamp core, module power supply, IC driver, control system, packaging technology and cabinet, etc.
Other equipment used mainly include: computer, audio power amplifier, air conditioner, power distribution cabinet, multi-function control card, and users who need it can also be equipped with TV card and LED video processor.
In addition, the manufacturing process of the display screen and the packaging technology of the lamp are also important considerations.
Dimensions
P3 and p2.5 are the most commonly used indoors. The small spacing with a dot spacing of ≤2 has better display effect and high definition, but the smaller the spacing, the more expensive it is.
Generally, it depends on the actual needs of customers. Video conferencing Classes generally choose p1.5-p1.8.
Since the viewing distance of indoor display screens is mostly limited (except for indoor stage screens), generally between 3 and 20 meters,
the main reference area for choosing an indoor full-color screen is the size of the indoor full-color screen.
The conventional one is more suitable for smaller areas, 10 square meters It is more affordable to choose a slightly larger spacing for the above.
Follow-up service
Subsequent maintenance and repairs are relatively simple. Monochrome display screens are generally used for outdoor door display, etc., and scrolling through different fonts is relatively straightforward. You can choose to be assembled by professionals or free to assemble. HOLA led display unit boards have perfect after-sales support.
For large-scale display projects, it is necessary to directly contact the LED display operator.
Whether it is price, strength, professionalism, or service depth, bidding procedures are obviously better than small service providers.
there will be greater protection for the screen in the future, and better cooperation will be obtained.
