Recently,2023 Connoisseur Says Display Annual Meeting and Connoisseur Aurora Award CeremonySuccessfully concluded. On the same day, the two topics of ecological exploration from small pitch to micro pitch and hot technology**: COB vs MIP attracted a lot of discussion, and the technical changes also caused many experts**Virtual pixelsIt is one of the hot technologies of this conference.
According to the 2023 small-pitch and micro-pitch display survey***, virtual pixel technology can achieve more resolution display effects with fewer LED chips through algorithms. On the one hand, virtual pixels reduce the amount of LED chips used and reduce material costsOn the other hand, the reduction in the number of LED chips can improve the first-pass rate and also help reduce costs.

In this conference,Unilumin TechnologyIndicates that dynamic (virtual) pixel technology uses a physical hardware cost investmentImplementation 25-3.Approximately 5 times the sharpness effectIt doubles the perceptible visual clarity of the picture and has a high cost performance.
In addition, Unilumin Technology also demonstrated its 3-lamp virtual pixel scheme (2 pixels and 1 group RGB lamp virtual pixel scheme (4 pixels and 1 group RGB), as well as the COB virtual pixel product UMINIP (P093、p1.2）
Zhongqi OptoelectronicsIt also demonstrated the virtual pixel technology using COB in the report, which is also P1In the case of 25mm, the RGGB4 lamp virtual pixel cost is only needed, RGB three-light sub-pixel cost required, RGB three-lamp virtual cost only
Zhongqi Optoelectronics
Hida ElectronicsIt is also stated in the report that COB dynamic pixel technology uses dynamic pixel + mini size miniaturizationThe total cost of chips will be significantly reducedThis is not possible with other technologies.
Kinglight StageIt is also said that MIP virtual pixel technology,It can reduce the number of MIP lamp beads by 75%.The number of LED chips is reduced by 666%, resulting in a significant reduction in costs.
In specific applications,MTC Crystal DisplayThe V168 series of virtual pixel products (P062/p0.78/p0.93/p1.25/p1.56/p1.87），ColorlightIt also said that its intelligent core detection equipment MICA can help virtual pixel technology.

Summary
This year, the competition and cooperation of COB, MIP and other technologies is a hot topic. The focus of development is how to grasp the needs of the market. Virtual pixels can reduce the number of chips and reduce costs, so as to promote the gradual sinking of smaller pitch products in the market, and on the other hand, it can also achieve low cost to achieve higher resolution. At present, virtual pixels appear in COB, MIP, and micro LEDs.
For example, at this year's SID2023, Porotech exhibited the world's first model for AR device applicationsMonolithic full-color Micro LED microdisplayThe product is based on Dynamic Pixel Tuning (DPT) technology.
And in general,This year, virtual pixels are more combined with COB, including many companies such as MTC Jingxian, in order to promote the reduction of COB costs and the sinking of applications.
In terms of technology, it should be noted that the core of virtual pixels lies in visual science, which not only needs to pay attention to the arrangement of pixels, but also needs the overall rendering technology, and also includes the cooperation of display control technology.
Unilumin Technology said that behind the virtual pixels, a variety of technical processes are required, including the placement of LED physical positions, the algorithm of sub-pixel reuse and rendering, information recording, the distribution of space and time sending, and the correction of the screen, all of which need to be supported by difficult mathematics, algorithms, processing and scientific knowledge of human vision.
At present, control system manufacturers such as:Nova Nebula, ColorlightIt is also helping to promote dynamic pixel technology, so that products using virtual pixels can achieve better display effects.
