LED rental display products will require frequent loading, unloading and repeated use according to different use locations and scenarios, making related products have higher requirements for product structure design and product production processes to ensure the convenient transportation and installation of rental LED displays. Service life and stable operation.
In addition, seamless splicing can be said to be one of the most important aspects of the structure design of the LED rental screen box. The seamless degree of cabinet splicing can directly affect the visual experience of multi-angle viewing on the LED full-color screen. At present, the LED rental displays advertised on the market are all emphasizing and highlighting its four major characteristics: portability, lightness and thinness, seamless splicing and shock resistance.
LED display manufacturers remind you that in addition to the general requirements of LED screens, rental LED displays also need to meet a series of special requirements in order to meet the needs and usage habits of rental customers.
1. The LED rental display must first meet the safety requirements
●Safety that can be checked quickly
Rental screens are often stacked high, or hoisted at a high place, and there will be cast and crew members and audiences nearby. Structural safety is particularly important. Due to the short installation time, it is unwilling to allow a long time to check whether it is firm, so the safety that can be quickly checked is particularly important. At a glance, you can know whether it is tightened or installed in place. If the installation is not in place, it will be obvious and easy to find.
●Strong tolerance to slight bumps during transportation and handling
Rental screens usually take longer to be transported on cars, boats, and airplanes than the lighting time. The tolerance to bumps in transportation is the requirement that the rental screens and their packaging boxes must meet. There may be occasions where vehicles cannot enter, and even the flight box cannot be pushed through. Manual handling is required. Minor bumps are unavoidable. Therefore, the product should not be too sensitive to bumps, and there should be no obvious deformation, paint peeling or damage due to slight bumps.
Second, the rental LED display must meet the requirements of fast loading and unloading
Almost all over the world, labor costs are on the rise. If the leasing products are not considered in this respect, it will increase the operating costs of the leaser.
● Fast installation and removal
The speed of installation and disassembly largely determines the customer's labor costs and the ability to intensively receive orders. Therefore, customers like products that can be quickly assembled, disassembled, and transported. This not only involves the design and performance of the screen and its accessories, but also the design of the packaging (air case).
●Less reliance on professionals
Usually, some of the personnel involved in installation site handling and structural assembly are temporary workers who have no experience in using LED displays. Therefore, installation without tools and no complicated training is a feature that rental screens need to meet.
●Support single-handed operation
Don’t design the work that can be done by one person to require two people to work together. For high-altitude operations, the safety of personnel should be considered, and the needs of one-handed operations should be met as much as possible.
●Quick partial replacement and repair
In addition to improving product reliability, rapid partial (module or cabinet) replacement is a special requirement for rental screens, which is different from fixed installation screens. Sometimes it takes more than two minutes to make it difficult for customers to accept.
●There should be fewer types of accessories and accessories, and the identification should be clear
The types of accessories and cables should be small, easy to identify, and usually use color or shape to make obvious differences to prevent mistakes (especially in the case of urgent time and poor light).
Third, the LED rental display must also meet the compatibility requirements
●Consistency of mixed use of multiple batches of products and ease of adjustment
For satisfactory rental products, customers will buy multiple times and the time span may be relatively long. At the same time, familiar customers will also use a certain product on large projects. Therefore, the rental screen must meet the optical consistency of the products within and between batches, so that customers can mix and match the screens at will. At the same time, customers can easily adjust the color and brightness of different batches by themselves to achieve an acceptable screen-splicing effect. This puts forward consistent requirements for the selection of panel materials, design and spraying, and the angle characteristics of the lamp. If a certain type of LED is discontinued and there is no alternative product with the same optical characteristics (please note that this problem cannot be solved by point-by-point chromaticity correction), it will cause us to be unable to provide customers with fully compatible and mixable products. Products (customers will be very annoyed and the consequences will be serious).
●Different varieties can share power supply and control system
Experienced leasing chambers require that the controllers, distributors, distribution boxes and other accessories of different products can be used universally. Many leasing companies with cooperative relations in the same area adopt a common standard to purchase certain types of leasing products.
Fourth, LED rental screens must also meet the requirements of the TV industry
TV is the largest mainstream media. The first impression that LED screens give people is that as an outdoor super-large TV, it occupies an important position in TV evenings, sports meets and various exhibitions.
●Normal gray scale and no flicker during shooting, which is a requirement that the rental screen must meet
Rental screens usually have TV cameras in the use occasions. Generally speaking, the shutter speed of the camera is 1/50s or 1/60s, and the refresh rate of rental LED displays is generally designed to be relatively high, and it is mainly based on the needs of TV cameras. (Although the camera can use a high-speed electronic shutter to reach a thousandth of a second or faster, professional videographers will not use it. Professional videographers can avoid flickering by combining a slower shutter with exposure. Mobile phones usually have a fixed aperture, using iPhone4S as For example, the aperture is 2.4, and the shutter for outdoor shooting in the daytime is about 1/1,600s. The electronic shutter speed can be very high. Such a shutter speed is still relatively difficult for an LED display).
●The TV industry requires LED displays to achieve excellent image quality and high refresh rate under low brightness
TV camera requires low-brightness display effect of LED display. At present, the brightness of mainstream indoor LED display products has reached 1,500 to 2,000 nit, which is almost double the previous era when it was usually around 1,000 nit. On the other hand, due to the improvement of the low-brightness adaptability of the camera, the brightness of the TV studio has been lowered. The typical illuminance has been reduced from about 800lux to about 500lux, which puts forward a higher display effect on the low-brightness state of the LED screen. Requirements (the LED display with a maximum brightness of 2,000 nits requires sufficient gray scale and refresh rate to be displayed at a brightness of 200-300 nits), which requires that the control system and hardware configuration of the LED display have sufficient resources to meet the high Brightness and low brightness state.
Five, LED rental display needs to meet other requirements
●Low noise
In some occasions, museums, concerts, etc. put forward requirements on the noise of LED display screens. Low-noise fans or fanless and low-noise power supplies are required. Sometimes to achieve this effect, higher requirements are placed on the power supply.
●Support stacking and hoisting
Rental LED displays usually support stacking and hoisting at the same time, and have matching quick installation accessories. In order to ensure the safety of stacking and hoisting, the rental LED display has a clear limit on the maximum number of layers for stacking and hoisting.
●Lightweight modular distribution box
Rental LED screens usually use lightweight distribution boxes, which do not require complex functions, but need reliability and easy maintenance.
●The connector has a long life and many plug-in times
The rental product has many installation times, so it is necessary to use a connector with a large number of insertion and removal times.
