In recent times, many OEMs have been placing an increasing emphasis on the looks of their device. This holds true especially with Chinese smartphone makers like Realme that try and offer unique colors and designs on their offerings. Now, Vivo is also looking to offer an eye catching device, which features a color changing rear panel.
In a video shared by the Chinese tech giant, a device can be observed that features a rear panel with shifting colors. The technology used to achieve this is based on electrochromism. For those unaware, this phenomenon allows the glass to change colors and opacity based on the voltage applied to it. In the short video, a Vivo engineer can be seen explaining the technology.

While Electrochromatic glass isn’t something new in the world, but it is largely an untapped resource in the smartphone industry. To explain in brief, two transparent electrode sheets are sandwiched with two glass sheets with an electrochromic film in the middle alongside an ion conductor and ion storage film. So when low voltage is applied, the ios change their consistency, which in turn, changes the light and how it bends when it passes through the EC film.
In another leaked video, the smartphone used to demo the technology appears to be a Vivo S7 5G, as seen by its rear camera module. So, we might see the inclusion of electrochromism in future Vivo smartphones. It is a low power technology so it won’t strain the battery life or cause the device to overheat. Notably, since the technology is transparent by nature, we can also expect a dynamic rear panel that varies in its opacity as well. Although we will have to wait and see when Vivo finally decides to ship this technology in its smartphones.
