At present, the application scope of big data continues to expand, and more and more companies are beginning to deploy big data strategies. At the same time, big data technology also makes business development faster and more efficient. Through big data technology, companies can more easily obtain information in order to make more accurate decisions. Many companies have already benefited from big data.
Why is big data gaining more and more attention? From the initial traditional business to the later cross-industry competition, the rise of e-commerce, and the catalysis of the Internet and mobile Internet, everything happened too fast, and you can’t wait for you to think too much. The era of big data has been I have brought it up, what has happened, and what is the future trend?
Service transformation money changes the flow
When the traditional business thinking is operating in "conventional sense", eating hot pot comfortably, singing songs, suddenly a group of "snap bandits" come, anti-virus software is free to use, free chat software appears, and the development of e-commerce , The market has undergone earth-shaking changes, and the flow of money has also changed with the changes in consumer experience. The cake is finally no longer enjoyed by those few people. In the future, the competition in the service industry will become more and more fierce. Convenient and affordable services will be the top priority.
The era of big data is coming, but "quantity" will no longer exist
With more and more data, the situation is becoming more and more complex. The competitive pressure of Internet thinking makes it more difficult to choose the future direction. It is natural for big data to be valued, but the development of big data is faced with the difficulty of sharing, high degree of monopoly, and poor integration capabilities. , A series of restrictive factors such as low application value and high security risk. Therefore, some experts believe that the "volume" of data is no longer the focus of data. Instead of blindly pursuing the amount of data, it is better to study how to improve the efficiency of the use of data at hand.
Big data will be divided into data blocks, which will break the restrictions on the flow of information in the industry. Through the cross-border aggregation of different types and fields of data, it will greatly change the production, dissemination, processing and organization of information, and then give each The innovation and development of the industry bring new driving forces to promote the radical transformation and reinvention of various fields. As far as the current cooperation strategies of major e-commerce companies are concerned, data has been divided into data blocks and data resource sharing has begun. This allows them to grasp more consumer demand information and will continue to optimize in marketing and logistics. .
As the amount of data continues to grow, data analysis methods will also be further improved. The requirements for terminal display equipment will also increase, and the size of the terminal screen directly affects the visual display and comparative analysis of data. At present, large-screen displays use splicing methods, which are mainly divided into three types: LCD splicing screens, LED small-pitch splicing screens and DLP rear-projection splicing screens. There is also a PDP splicing screen, which has been gradually eliminated due to its shortcomings such as high power consumption and heat generation, and diminishing picture quality over time.
In the era of big data, commercial display manufacturers cannot just come to "hard" LCD splicing.
In terms of brightness, there is no need to worry about the three splicing technologies being insufficient. Although the brightness of DLP splicing is gradually increased after the use of a laser light source, due to the different imaging principles, there is still a gap between the splicing screens that are actively illuminated by LCD and LED in resisting natural ambient light. However, in most applications, DLP splicing The brightness still meets the basic needs. On the contrary, the small-pitch LEDs, which are known for their high brightness, face the problem of over-brightness. One of the main marketing techniques for small-pitch LEDs is "low brightness." In contrast, liquid crystal appears more appropriate in terms of brightness level, and is suitable for large display screen applications.
In terms of contrast index, small-pitch LEDs are the highest, and the gap between DLP splicing units and liquid crystals is not very large. From the demand side, the contrast of the three major technologies exceeds the actual display needs and the resolution limit of the human eye. This makes the contrast effect, the pros and cons of the three technologies more dependent on the optimization of the software, rather than the limit value on the hardware.
In terms of resolution (ppi) indicators, although small-pitch LEDs have been breaking through, they still cannot compete with DLP splicing and LCD splicing. At present, only liquid crystals can achieve the popularization of 2K on 55-inch units, and only LCDs are expected to popularize 4K in the future. For small-pitch LEDs, higher pixel density means that the difficulty of stable design has increased geometrically. It is worth reminding that the "real value of the pixel density advantage of liquid crystals is not very clear", because users rarely demand That high pixel density.
The reaction speed indicator is mainly aimed at the tailing problem of dynamic pictures. This is one of the most significant weaknesses of liquid crystals. For the other two technologies, there is basically no visually visible lack of response speed. The nature of the tailing of the liquid crystal is not because the reaction speed of the liquid crystal is lower than the limit of the naked eye, but because of the delay superimposition caused by the moving elements in the picture on the distance. This principle determines the disadvantage in response speed, and does not significantly affect the application of the product in most customer needs-most market requirements for large-screen video walls do not focus on sports effects.

The index of color range is generally not the most concerned direction of splicing wall products. In addition to applications such as radio and television, the splicing wall market has never been strict with regard to the demand for color reproduction range. From a comparative perspective, small-pitch LEDs are natural wide-color gamut products. DLP splicing and liquid crystal depend on the light source used.
Refresh frequency is a key indicator to effectively suppress the flicker of the screen picture. The refresh rate of LED screens is generally very high, DLP can also reach the level of 60-240HZ, and most of the liquid crystals are at the level of 60-120HZ-all exceeding the human eye's resolution limit.
Editor's conclusion: The era of big data needs to strengthen software development to obtain valuable information in big data, but at the same time as software development, strong hardware support is needed. Whether it is in the era of big data, or striving towards a smart city, the purpose is all In order to facilitate users, let users have a better interactive experience, and life is more convenient and faster.
