How to reduce the light pollution brought by LED displays?

With the expansion of the LED display market, more and more LED screens bring about some light pollution problems, which have an impact on government legislation and market orientation, and also cause damage on LED display business.

Therefore, we suggest the following 4 points to be considered to reduce the possibility of light pollution:

1. The regulating system can automatically adjust the brightness by outdoor brightness acquisition system. At any time to collect the data of the ambient brightness, the display control system will collect data received by software analysis, automatic adjustment the brightness for broadcast environment.

2. The multi-level gray correction technology: using 14bit color control system to replace the ordinary 8bit display system, people can feel the color soft when watching the display, and to avoid the abrupt color phenomenon which causes people to create a sense of the discomfort of light when the LED display is playing a low gray scale and color excessive video and images.

3. Reasonable planning and reasonable choice of installation position: A specific design requirement is needed, viewing distance, viewing angle and the display area should be reasonable as far as possible at the designing and planning step.

4. The selection and design of the broadcast content: LED display is the public media; there are public welfare, advertising, instructions and so on. When we select the content of the broadcast, we must reach agreement with the public, so as people will not refuse to watch. This is also an important aspect of preventing and controlling light pollution of display screen.

The above methods are in fact not too difficult to achieve, most of the light pollution are caused by high brightness over seeking. In fact, if the screen brightness of the led screen is not exceeding 60% of the ambient brightness, and the stimulation of the human eye would be limited, also reduce the light pollution to the whole environment.  

Promising LED in the digital signage market

In recent years, the digital signage market has grown rapidly, and it is estimated that the display market will continue to grow at a CAGR of 16.7% by 2021. It’s reported that the global shipments of digital signage monitors increased by 19.7% in 2016, about 10.5 million units, the growth is driven by an increase in demand for vertical markets, technological advances and continued declining prices.

This vast blue ocean market has attracted the attention of many LED display enterprises. In many industry exhibitions, many LED display companies have launched LED digital signage products and related solutions, many of them already have some very exciting project cases. Although compared to LCD, LED display advantages in terms of price is small, the LED display technology have a brilliant future in the aspects of display effect ,durability and easy maintenance.

In addition, as a new area of LED display applications, digital signage field is entirely a new field, LED display companies give full play to the enthusiasm of innovation, and constantly integrate some new technologies, such as touch, recognition, human-computer interaction and process tracking, including 3D technology, remote control, WIFI positioning and other cross-border forms. These technologies create more possibilities for the future of LED digital signage.

CRIUS V4 integrated mobile phone APP control, WIFI communication and recognition technology, QSTECH is the first to achieve accurate display in LED industry, and provide users with highly intelligent digital signage solutions.

LED display development in 5 years

The export amount of LED will keep rising by 16% in next 5 years.

Market survey from HIS claims that there is big chance the export of direct-view LED video display will maintain 16% booming annually during 2016~2020.

Chief of HIS science & technology digital signage, San jukhatri said:“application of LED video business differs from other technologies. Owing to less usage of LED in commercial and educational industry, whose clients tend to use front projector and LCD. The popular application of LED display belongs to retails & outdoor sports, such public places. The wide range in publics, retails, control rooms which stand for indoor application seems to increase instantly.”　

HIS predicts that the research & develop small pixel pitch will slow down in short terms, because it’s subject to the size of LED seal, plus the price rising of 1.9mm and below 1mm.

According to the report of Persistence Market Research, the global outdoor fixed installation of LED will be 15.7 billion till 2021. It is the majority sales volume of LED. Outdoor LED advertising display will take 46%. outdoor fixed installation of LED will keep increasing exceed 16% steadily. 

LED display in age of mega data

At present, LED which stands for new digital media develops much faster, we are looking forward to figure out the chaos of LED outdoor installation, aim at developing the outdoor advertising further way. Only on the basis of big data, will outdoor advertising industries catch the development chance, both management of outdoor advertisement and scientific or digital evaluation need to base on the big data. In order to help the clients to advertise precisely in end markets, and serve the audiences better via big data. 

QS tech start putting investment into Crius digital product platform, especially for the mobile terminals. Besides outdoor advertising area, some control system enterprise from LED industries begin with big data analysis of sports events. So, the big data has a good perspective.
