Chinese mobile phone manufacturers are interested in 1.5K high-frequency

Xiaomi Redmi K50 Extreme Edition was released on August 12. It uses a 1.5K OLED straight screen and is jointly developed with two screen partners, Tianma and Huaxing Optoelectronics. Lu Weibing said that the 1.5K screen of the Redmi K50 Extreme Edition can achieve a power consumption close to that of a 1080P screen, which is also the result of innovative hardware and software upgrades. Now it seems that the 1.5K screen will not only appear on the Redmi K50 Extreme Edition but also more mobile phones will be equipped with such a screen. According to Weibo blogger @Digital Chat Station, "1.5K" high-frequency dimming domestic flexible screens will be launched one after another, mainly used in mid-to-high-end and sub-flagship models, and a lot of plans are planned from the end of the year to the next year.

According to reports, the 1.5K screen of the Redmi K50 Extreme Edition has the following features:

  1. The double-layer circuit trace design has lower resistance and lower power consumption than single-layer traces.
  2. Increasing the pixel aperture ratio increases the efficiency of light passing. To achieve the same brightness, the required current is smaller and the luminous efficiency is higher.
  3. Intelligent circuit control to dynamically adjust the light-emitting device to drive the voltage, adjust in real-time according to the screen brightness, and appropriately reduce the power when high voltage is not needed.

The 1.5K straight screen of the Redmi K50 Extreme Edition has a pixel density of 446PPi, and is Redmi's first 12bit screen with up to 68.7 billion colors while supporting 1920Hz high-frequency PWM, hardware-level low blue, and obtaining SGS low vision Fatigue certified phone.
