Answer: A. Convenient and flexible installation
Answer analysis:
When discussing the advantages of LED rental displays, we must first clarify the main application scenarios and design features of LED rental displays.
LED rental displays are usually used for temporary large-scale events, performances, exhibitions and other occasions, so their design needs to meet the needs of fast installation, disassembly, transportation and flexible configuration.
Now, let's analyze each option one by one:
A. Convenient and flexible installation: This option directly corresponds to the core advantage of LED rental displays.
Since rental displays need to be frequently installed and disassembled in different occasions, their design must take into account the convenience and flexibility of installation.
This type of display usually has a modular design and can be quickly assembled and disassembled to adapt to different venues and layout requirements.
B. Thicker cabinets: This option does not constitute an advantage of LED rental displays.
On the contrary, thicker cabinets will increase the weight and volume of the display, which is not conducive to rapid transportation and installation.
In the rental market, lightweight and compact designs are more popular.
C. Lightweight: Although lightness is a positive feature for LED rental displays, it is not its most significant or unique advantage. Lightness is more of a design consideration than a core advantage of rental displays.
D. Not easy to disassemble: This option is obviously contrary to the actual needs of the LED rental display.
The rental display needs to be frequently disassembled and assembled.
If the disassembly and assembly are inconvenient, the use cost and time cost will be greatly increased.
In summary, the main advantage of the LED rental display is that it is easy and flexible to install.
This flexibility is not only reflected in the rapid assembly and disassembly, but also in the flexible configuration and adjustment according to the needs of different occasions.
Therefore, the correct answer is A. Easy and flexible installation.
