What is the difference between outdoor LCD advertising machine and home LCD TV
From the appearance, outdoor LCD advertising machine and home LCD TV are indistinguishable to many people. Because they can meet the needs of desktop, wall hanging, hoisting, horizontal and vertical installation, they can be designed for different needs of various occasions. They are all used to play dynamic pictures. They can also be operated remotely. They look like twins. But they are completely different, and there are great differences in the categories of consumer groups. Today, the small series of outdoor advertising machine manufacturers will tell you how to distinguish between outdoor LCD advertising machine and household LCD. The details are as follows:
1. Differences in design
On the premise of good video and picture display, commercial LCD splicing wall and household TV are different in appearance design, user group attribute, structure, IC chip and circuit structure. For LCD TV, it needs to be placed in the living room, bedroom and other home environment, so it needs to be well matched with furniture. Designers usually start with TV color matching and modeling; However, for the commercial LCD splicing wall, people often pay attention to the video content it plays, rather than the product itself, so we can see that the body of the commercial LCD splicing wall is square, very simple and simple, and the color is black.
2. Equipped with different interfaces
LCD TV interface is very rich, but commercial LCD splicing wall is not necessary. They are usually equipped with the most basic interfaces that can be seen in traditional displays, such as DVI and D-sub, while new commercial displays will gradually add DisplayPort interfaces. In order to input video signals with higher resolution when multi screen splicing. For some special occasions, such as outdoor environment with high temperature and low temperature, commercial LCD splicing wall usually has the functions of overheating protection, heating, high brightness, waterproof and so on. LCD TV is generally located indoors with good environment, which does not have these characteristics.
3. The products of different IC cores are different
Although they have "telepathy" like twins, they think differently in some places. Another difference between LCD TV and commercial LCD splicing wall lies in IC chip and circuit design structure. The main function of LCD TV is to play TV programs, videos and game pictures, focusing on the definition of dynamic pictures, and the accuracy of color reproduction is not so strict. Therefore, LCD TV IC chip mainly optimizes the dynamic effect of image and the brightness of color.
Commercial displays mainly play static pictures, text or dynamic video. Therefore, manufacturers will adopt different calibration methods for different purposes and pay more attention to the accuracy of color reproduction, which is very different from the calibration of LCD TV. High end models will also have a built-in color calibration system.
4. Differences in consumer groups
Different user group attributes lead to completely different design concepts. As far as LCD TV is concerned, it is mainly for the public and individual users. It is an essential item for almost every family. Usually, their main purpose is entertainment, which is the carrier of TV programs, movies and games; The commercial LCD splicing wall is mainly for users in business, public information display, medical treatment, education and training and other industries. Although the broadcast content is basically the same as that of LCD TV, the users who buy commercial LCD splicing wall products are basically not individuals, but enterprises, administrative units, medical and educational units, institutions, etc. The purchasing groups they face are very different, so for manufacturers, they give these products different characteristics according to their different ideas and attributes.
For ordinary individual users, they need LCD TVs with fashionable appearance, personality, convenient operation, stable quality and excellent display effect. For industry users, the working time of commercial LCD splicing wall is usually 724 hours, so more stringent requirements are put forward for the stability, reliability, loss resistance, aging resistance and low power consumption of product quality.
