At present, full-screen mobile phones have become the mainstream mobile phone design direction. In the case that major manufacturers are constantly pursuing higher screen ratio, some mobile phone manufacturers have launched off-screen camera phones, and put the front camera at the bottom of the screen. Although this can present a complete screen on the front of the mobile phone, the technology is still immature and there are still some shortcomings. For example, the front camera can still see through the screen at a specific angle, and the imaging quality is different from that of the conventional camera.
VIVO, a domestic mobile phone manufacturer, seems to intend to achieve a full screen in another way. At present, VIVO has applied for related patents. This technology allows the mobile phone to hide the selfie camera when not in use, and even has two front cameras, which makes the selfie more fun.
In late June of 20021year, VIVO applied to WIPO for a practical patent for "screen control method and device and electronic equipment", and the patent document was officially published on February 30, 20021year.
Judging from the patent documents applied by VIVO, the highlight of this patent invention of VIVO is that VIVO is equipped with a flexible display screen for the mobile phone, and some display screens are curled in the upper and lower housings, and rollers are used on both sides, and the display screen is curled around the rollers. Mobile phone scrolling screen can not be used to increase the screen area, mainly used to hide the camera lens. The flexible display has a hole, which is completely hidden under the top frame when the front camera is not used. If necessary, the display screen will slide down, and users can use the front camera normally by punching holes, while the display screen can continue to slide and use the second selfie lens.
Compared with the simple off-screen camera phone, VIVO is undoubtedly more creative in realizing a full-screen mobile phone, but at present, its disadvantage is also obvious, that is, the cost control of flexible screen may be higher than that of ordinary off-screen camera phone. So at this stage, it may be more as a patent. If mass production is to be carried out, it is impossible to estimate in a short time.
