Redmi K40 uses the E4 AMOLED screen for audiovisual & gamers

Redmi K40

In a few days (February 25th), Redmi will unveil its latest flagship smartphone, the Redmi K40 series. It is already public knowledge that this smartphone will come with an E4 AMOLED screen. This is the same display that the Xiaomi Mi 11 uses. However, Redmi’s president, Lu Weibing, recently explained why this device will use this display.

Firstly, the Redmi K40 will be the first smartphone to come with an E4 AMOLED screen. According to Lu Weibing, the Redmi K40 adopts the E4 AMOLED straight screen to “create a perfect screen for users who like straight screens”. In addition, Lu Weibing claims that the Redmi K40 will use a 120Hz refresh rate. 

Furthermore, Lu Weibing believes that there are always users who have a soft spot for straight screens. He claims that there is no difference between the straight screen and the curved screen. However, the curved screen gives a higher display ratio and is thinner and lighter while the straight screen feels better and is suitable for audio-visual and gaming scenarios. Thus, the Redmi K40 is coming to give users a better audiovisual and gaming application.
