When it comes to outdoor LCD display hardware equipment, for now, it mainly includes outdoor LCD display and player equipment. As trend-leading equipment, they are the main force for manufacturers' technological innovation, not only the update speed is fast, but also the variety is varied. Taking the outdoor LCD display as an example, every two to three years, the outdoor LCD display will be lighter, brighter, more efficient in power consumption, and provide higher resolution. Moreover, there are outdoor LCD display, LCD splicing screen, small-pitch LCD large screen and other options.
In order to ensure investment efficiency, "everything starts from actual needs and avoids blindly chasing trends" has become the basic principle for end users to purchase. For the selection of outdoor LCD displays hardware equipment, we summarize the following four major misunderstandings that need to be avoided:
Under the inertial thinking of human beings, the longer the service life of the product, the better, and this is no exception when purchasing outdoor LCD monitors. But from a long-term perspective, this kind of thinking is not advisable. It should be known that the longer the service life of the outdoor liquid crystal display, the higher the technical requirements, the corresponding increase in the manufacturing cost, and the higher the investment for industry users.
In order to ensure the return on investment, industry users will choose to extend the LED and LCD display use time as much as possible, and the direct consequence is that they cannot experience the latest technology in time.
Balance the cost of use and the application experience. When purchasing an outdoor LCD display, users should not blindly pursue long life. According to the application needs, it is just fine, so that the saved funds can be invested in the software content level to ensure the outdoor LCD display. The system reaches the best application state.
In the field of outdoor liquid crystal display nowadays, highlighting has become an important parameter to show the leading technology, and it has been infinitely enlarged in the marketing promotion of some manufacturers, which has directly led to serious highlighting episodes for many users.
In fact, the brighter the screen is not the better, the effect of screen brightness is a superposition effect, including contrast, viewing angle, viewing distance, brightness of the surrounding environment, playback content, etc. Therefore, simply pursuing high brightness may not necessarily achieve The best application effect will even have negative effects. For example, the higher the screen brightness, the more heat generated, the power consumption will increase, not only the expected service life will be shortened, but also the maintenance cost will be increased. The high cost of the product itself, thereby greatly increasing the capital investment, does not conform to the established economic principles. At the same time, in indoor digital signage applications, an excessively bright screen may also cause discomfort to the human eye, thereby affecting the viewing experience of the audience.
At present, many commercial digital signage displays are equipped with metal casings. Under the vigorous guidance of manufacturers, many industry users have also been convinced that metal casings are safer.
In fact, unless the outdoor LCD screen is installed in a public space that people can tamper with at will, the metal casing becomes a completely unnecessary expense. For example, elevator billboards in offices, menu boards in fast-food restaurants, and information displays at the cashier at the back, which are almost inaccessible to outsiders, are obviously very suitable for plastic enclosure applications.
For the purchase of LCD players, the smaller the volume, the better. Due to the demand for beautiful design, many users prefer to choose products with small size, which is understandable, but also pay attention to moderation.
Although compact player products are more flexible in installation, they put forward higher requirements for heat dissipation design. The increase in technical threshold not only leads to high costs, but also increases the potential risks of system application. After all, liquid crystal display requires 7x24 hours of continuous operation. Once there is a problem with heat dissipation, the consequences are unimaginable.
