“In 2017, there is a hot word in the display field--small spacing. At present, the indoor small-spacing market is hot, so from the perspective of technological development, how is the outdoor small-pitch development? How will it be positioned?†Dr. Shao Pengrui of Jingtai Co., Ltd. Gaogong LED was presented at the annual meeting.
From December 21st to 22nd, 2017, the 2017 High-tech LED Annual Meeting and Golden Globe Awards Ceremony hosted by Gaogong LED was held at the Baoding Dunxi Road in Shenzhen Baoan. The big hotel opened.
As the annual year-end event of the LED industry chain, the 2017 High-Tech LED Annual Meeting will once again bring together the LED LED industry leaders, and the on-site 400+ industry elites will fully look forward to the LED industry landscape, market, capital, technology trends and trends, deep integration and Excavate new opportunities and strategies under the current industrial situation, and jointly solve the "decisive victory" of industry and enterprises.
On the afternoon of December 21st, Jing Peng Opto's "Opening Conference: Focusing on the Industrial Opportunities and Corporate Strategies in the Chinese Market", Shao Pengrui delivered a keynote speech entitled "From the technology to the market, the future shows the packaging trend".
Dr. Shao Pengrui, Jingtai Shares
Shao Pengrui said that my understanding is that the outdoor small-pitch size grade will be one level higher than the small-size resolution of the same size in the future, that is, the early outdoor screen and the fixed installation of the large screen will turn to the commercial door, pedestrian street, and window in the later stage. , advertising machines, bus shelters, newsstands, gas stations, shopping kiosks and other application areas.
In addition, the rental market, the development of small indoor spaces will develop towards small outdoor spaces, and will bring a bigger market to both indoor and outdoor rental markets. At present, the indoor high-definition P3 has become the mainstream, mass production P2.5/1.9/1.6/1.2/0.95; while the outdoor leased high-density P3, P4 accelerates development, and even develops indoors like P2.5.
Shao Pengrui said frankly that our slogan is compatible development of the rental market inside and outside the home.
As far as the outdoor display is concerned, it has the following three characteristics:
First, far and near, from a fixed installation at a close distance to a fixed installation at a close distance;
Second, high density, because high density brings about an increase in capacity;
Third, full-color full-color, all the technology related to display is full-color, monochrome will slowly withdraw from the stage of history.
Based on the above characteristics, the current outdoor display mainly focuses on the following three aspects. First, solve problems with and without; second, solve problems with good and bad; third, focus on good and better problems.
What is the display now? In Shao Pengrui's view, this current domestic social contradiction is related, that is, the contradiction between the people's growing need for a better life and the under-balanced development, that is, the difference in display demand is increasing.
In fact, now everyone is more concerned about the visual effect, like the mobile phone display, the display is not clear enough, the drift is not beautiful, the display is not enough.
According to market research, the audience has the main reference for the image on the display: resolution, brightness, viewing angle, and color saturation.
Resolution:
Resolution P, viewing distance D, minimum viewing angle θ
P=D*tanθ=D*0.291
The application scene changes, and the specification requirements of the lamp bead device are increased.
saturation:
Take P10 as an example (pixel pitch 10mm, minimum viewing distance 35m)
The device does not match, the image quality is seriously reduced, and the graininess is enhanced.
Brightness and contrast
In the same maximum brightness, it can be increased by 2 to 5 times.
Under the same chip configuration conditions, there is an increase of more than 50%.
Perspective
In the case of SMD devices alone, the visual graininess is increased and the visual angle of the upper and lower sides is lowered.
"Of course, different application scenarios have different standards for the above four key parameters. For example, in terms of resolution, the range of resolution is required to be viewed from a long distance; in terms of brightness, the brightness is required when viewed from a distance. High; at the same time, taking into account both saturation and viewing angle. From a packaging perspective, how to match these high-quality solutions? This is the focus of packaging enterprise research. Display demand differentiation of light source devices is the mainstream of high-quality visual development in the future." Finally concluded.
