Many Android phones use O- LED screens, such as the Nexus One. For example, DroidIncredible, the OLED screen is divided into many small pixels, and there are many color channels in the screen. In the test we found that the red channel area is the most energy efficient. In the mode of working in the red channel, assuming that the unit power consumed by the mobile phone is "i" at this time, the green channel working mode is "1.5i", and the blue channel working mode is "2i".
Five colors reveal OLED screens with less power consumption mystery
If you take it out alone, just let the screen display one of the colors and then count their power consumption. What will happen? We set the phone to flight mode, and turn off the GPS. Using a test called SurfaceFlinger for image display power consumption, we can find that the data in red mode is in a leading position, whether it is a browser, a map, etc. The power consumption of the function is the smallest.
Five colors reveal OLED screens with less power consumption mystery
In the same time performance, the screen in red mode only consumes 42% of the total power, which is the least of all modes. Although such a test does not represent an official structure, it is still convincing.
