Outdoor lcd display panel.The price and quality of LCD screen. Recently, the slogan of ultra-low price competition has appeared frequently in the outdoor LCD display market: want to seize the outdoor LCD display market with low price.

However, after multi-market investigation, it is found that some products with ultra-low prices are not up to standard, including insufficient brightness, poor heat dissipation, ultra-high energy efficiency ratio of lamps and beads, not resistant to high temperature, shell Jerry, easy to rust, poor dustproof, design defects, high failure rate of electrical devices, chaotic internal structure, etc., and there is serious false propaganda at the same time. Therefore, in order to let the market and customers have a correct understanding and judgment of outdoor LCD display, as a senior expert in the industry, I think it is necessary to make an analysis of the price of outdoor LCD display.

In fact, outdoor LCD displays, like other products such as cars, have different prices, but more often, the prices are not comparable, especially the outdoor LCD displays that are now on the market:

1) there is no comparability between unqualified products and qualified products.

2) there is no comparability between products with different configurations.

3) the products with different technological generation differences are not comparable.

4) products of different grades (to meet different levels of customers) are not comparable.

Therefore, the current outdoor LCD display screen is also complete and qualified and unqualified era, qualified products are very few, the price is completely incomparable.

However, thanks to the fact that the new infrastructure has recently become one of the most important focal points for the country to stimulate economic development, the relevant intelligent urban outdoor display devices such as intelligent transportation and intelligent parks, in which the intelligent bus stop board is the core product, it has attracted wide attention from various industries, and the fundamental reason is that the intelligent bus stop is a natural station of 5G platform. Intelligent bus stop sign related communications industry, urban planning and design institute, traditional advertising industry, online media platform, system integration industry are all scrambling to enter, even Huawei, Ali, Dahua, Haikang, BOE, Zhouming, Huaxing Optoelectronics, Urban Construction, China Railway and other central enterprises have set up teams to join in, for a time 5G intelligent bus stop signs are the same.

Outdoor LCD display screen, an important device on the intelligent bus stop, has also become a big hot spot, causing a stir in the outdoor LCD display industry. Dozens of new companies have advertised that their companies make outdoor LCD displays, and some enterprises have even started to promote them everywhere with low prices as the selling point, which is also the usual style in the outdoor LCD display industry. No matter what the quality requirements of the project or customers are, their strategy is always only one: “attract you first at a low price, and then get the order.”

In fact, there is little relationship between outdoor LCD display and indoor LCD display. In outdoor LCD display, the module of outdoor LCD display is completely different from that of conventional display, such as structure, backlight, LCD panel, driver and so on. Outdoor LCD display screen should be in line with urban characteristics, surrounding architectural style structure, different parameter requirements, different functional requirements, different installation methods, different use environment, intelligent control, and these technologies are difficult, virtually increased a very large cost, but these are the key points to determine whether the outdoor LCD display screen is qualified or not.

Outdoor LCD display screen requires more than 2500CD brightness, the current market is the purchase of liquid crystal glass assembly screen, LCD panel quality, backlight LED bead brand, lamp bead use energy efficiency, structure, diaphragm, light guide plate, board design circuit, etc., these are important factors that affect the stability and life of the highlight LCD screen. However, the quality, price and stability of these accessories, the selection of different manufacturers are different, the embarrassing thing is that the quality of the screen of different manufacturers needs to be verified over time.

There are three kinds of glass used in outdoor advertising machine, AR glass, AG glass and ultra-white toughened glass, usually AR glass.
