LED rental display installation precautions
LED rental display products will be frequently loaded, unloaded and reused according to different use locations and scenarios, so that related products have higher requirements on product structure design and product production process to ensure the convenient transportation, installation, and production of rental LED displays. longevity and stable operation.
In addition, seamless splicing can be said to be the most important aspect of the structural design of the LED rental screen cabinet. The seamless degree of cabinet splicing can directly affect the visual experience effect of multi-angle viewing of the LED full-color screen. At present, the LED rental displays on the market are emphasizing and highlighting their four major features: portability, 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
● Security that can be checked quickly
Rental screens are often stacked high, or hoisted at high places, with cast members and audiences nearby, and structural safety is particularly important. Due to the short installation time, it is impossible to set aside a long time to check whether it is firm, so the safety that can be checked quickly is particularly important. At a glance, you can tell 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 in transportation and handling
The rental screen is usually transported on a car, ship, or plane for longer than the lighting time. Tolerance to transportation bumps is a requirement that the rental screen and its packaging must meet. There will be some occasions where vehicles cannot enter, and even the air box cannot be pushed through, requiring manual handling. Slight bumps are unavoidable, so the product should not be too sensitive to bumps, and minor bumps should not have obvious deformation, paint peeling or damage.
2. The rental LED display must meet the requirements of quick loading and unloading
Labor costs are rising almost all over the world. If this aspect of leasing products is insufficiently considered, it will increase the operating costs of the leasing companies.
● Faster installation and disassembly
The speed of installation and disassembly largely determines the customer’s labor cost and the ability to receive intensive orders, so customers like products that can be assembled, disassembled and shipped quickly. This not only involves the design and performance of the screen and its accessories, but also the design of the packaging (air box) will have a great impact.
●Less reliance on professionals
Usually, some of the personnel who install on-site handling and structural assembly are temporary workers who do not have experience in using LED displays. Therefore, installation without tools and without complex training is a feature that rental displays need to meet.
●Support single-person operation, one-handed operation
The work that can be done by one person should not be designed to require the cooperation of two people. When working at heights, considering the safety of personnel, the needs of one-handed work should be met as much as possible.
●Quick local replacement and repair
In addition to improving product reliability, being able to perform rapid local (module or box) replacement is a special requirement for rental screens that are different from fixed installation screens. Sometimes it takes more than two minutes for customers to accept.
●There should be fewer types of accessories and accessories, and the identification should be clear
Accessories and cables should be of few types, easy to identify, and usually clearly differentiated by color or shape to prevent mistaking (especially in the case of time constraints and poor lighting).
3. The LED rental display must also meet the requirements of compatibility
●Consistency of mixed use of multiple batches and convenience 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 a large project. Therefore, the rental screen must meet the optical consistency of products within batches and between batches, so that customers can mix and match screens arbitrarily. At the same time, customers can also easily adjust the color and brightness of different batches to achieve an acceptable screen effect, which puts forward consistent requirements for the selection of panel materials, design and spraying, and the angle characteristics of lamps. If a certain type of LED is discontinued, and there is no substitute for the same optical characteristics (please note that this problem cannot be solved by point-by-point chromaticity correction), we will not be able to provide customers with a fully compatible mix of Product (customers will be annoyed with serious consequences).
●Different varieties can share power supply and control system
Experienced leasing companies will require that the controllers, distributors, distribution boxes and other accessories of different products can be used in common use, and multiple leasing companies with cooperative relations in the same area use common standards to purchase certain types of rental products.
4. LED rental screens must also meet the requirements of the TV industry
TV is the first major mainstream media, and the first impression of LED screen is that it is an outdoor super-large TV, occupying an important position in TV parties, sports games and various exhibitions.
The grayscale is normal and flicker-free when shooting, which is a requirement that rental screens must meet
Generally speaking, the shutter speed of the camera is 1/50s or 1/60s, and the refresh rate of the rental LED display is generally designed to be relatively high, mainly considering the needs of TV cameras. (Although cameras can use high-speed electronic shutters to a thousandth of a second or faster, professional videographers do not use this. Professional videographers can avoid flickering by combining exposures with slower shutters. Mobile phones usually have fixed apertures, such as the iPhone 4S. 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, and such a shutter speed is still relatively difficult for LED displays).
The TV industry requires the LED display to achieve excellent picture quality and high refresh rate at low brightness
TV cameras have low-brightness display requirements for LED displays. At present, the brightness of mainstream indoor LED display products has reached 1,500 to 2,000nit, which is almost double the previous era when it was usually around 1,000nit. On the other hand, due to the improvement of the low-brightness adaptability of the camera, the brightness of the TV studio has been reduced, and the typical illuminance has been reduced from about 800lux to about 500lux, which provides a higher display effect for the LED screen in the low-brightness state. Requirements (LED display with a maximum brightness of 2,000nit requires enough grayscale and refresh rate to display at a brightness of 200-300nit), which requires the control system and hardware configuration of the LED display to have sufficient resources to meet the high requirements at the same time. Brightness and low brightness states.
5. Other requirements that the LED rental display needs to meet
In some occasions, museums, concerts, etc. have put forward requirements on the noise of the LED display, and it is necessary to use a low-noise fan or no fan and a low-noise power supply. Sometimes, in order to achieve this effect, higher requirements will be placed on the power supply.
●Support stacking and hoisting
Rental LED displays usually support stacking and hoisting at the same time, and there are matching quick installation accessories. In order to ensure the safety of stacking and hoisting, rental LED displays have a clear limit on the maximum number of layers for stacking and hoisting.
●Lightweight and modular distribution box
Rental LED screens usually use lightweight distribution boxes, which do not require complex functions, but require reliability and easy maintenance.
●The connector has a long life and many times of plugging and unplugging
The rental products are installed many times, and the connectors with many times of plugging and unplugging should be used.
