Reel screen mobile phones are still at the level of concept phones, and thinness, cost, and yield are issues that need to be broken down in the next step.

The folding screen has not yet become a mass product, OPPO has already focused on the scroll screen.

On November 17, OPPO released a concept phone OPPO X 2021 at the Future Technology Conference. Compared with the folding screen with a fixed screen size, the scroll screen can be stepless from a minimum of 6.7 inches to a maximum of 7.4 inches. adjust.

Compared with folding screen phones, this scroll screen phone also achieves the purpose of changing the phone screen and can eliminate creases.

However, the scroll phone is still in the concept stage, and there are some unresolved problems. For example, the diameter of the reel of the mobile phone reaches 6.8mm, not counting other horizontal structures. Jin Xiang, the hardware structure engineer of OPPO Research Institute, told that in the future, the product will not give up the classic selling point of light and thin OPPO mobile phones, so the next product structure needs to be refined.

In addition, the landing of the product needs to achieve a certain yield. Jinxiang told that the current internal yield test shows that the mobile phone can reach a lifespan of 5 years after 50 operations per day.

The price is also a concept machine.Vector produces the biggest problem. Liu Chang, the dean of OPPO Research Institute, told me that a lot of verification work has been done on the yield rate. Although the cost of launching to the market has not yet been calculated, it will eventually be a “relatively reasonable price” if it is listed.

In the exploration of mobile phone screen form, the current more unified direction is still the folding screen. Only Samsung, Motorola and Rouyu have launched mature folding screen mobile phone products. Xiaomi and Apple have alsoWith relevant patent reserves, more mainstream mobile phone manufacturers will launch corresponding folding screen products next year. Liu Chang said that OPPO has not given up the folding screen, which is also one of the most important product lines on the research institute’s technology shelf.

In addition to the scroll screen, OPPO also released two other concept products that day: AR glasses OPPO AR Glass 2021 and the full-time spatial computing AR application OPPO CybeReal.

OPPO AR glasses adopt a “split design”, which has been further improved in terms of wearing experience, optical solutions, interactive methods, and content ecology compared with the concept products released at the Future Technology Conference last year. Some OPPO people said that the new concept product has a product plan change compared to the previous generation, and pays more attention to the landing scene. This time OPPO’s AR glasses and iqiyi and JD.com have both explored family movie viewing and shopping scenes Landing.

The third concept product CybeReal released this time is a software-side product that can provide high-precision full-time positioning and scene recognition experience.

At the OPPO Future Technology Conference, founder Chen Mingyong once again appeared and released OPPO’s“3+N+X” technology transition strategy. “3″ refers to the basic technology of hardware, software and services. “N” is the long-term competence center built by OPPO, including artificial intelligence, security and privacy, multimedia, Interconnection etc. “X “Refers to OPPO’s differentiated technologies, including images, flash charging, new forms, AR, etc.
