Redmi K40 series uses a 120Hz OLED straight screen: may be the most expensive in history

Today, Lu Weibing, Vice President of Xiaomi Group, and General Manager of Redmi Brand released some spoilers regarding the upcoming Redmi K40. His post Weibo post reveals quite a few important information. The most important is probably the price. According to Lu Weibing, the Redim K40 will start at 2999 yuan which is approximately $463. According to @DigitalChatStation, the Redmi K40 series will adopt a 120Hz OLED full screen. Furthermore, Lu Weibing and Wang Teng confirmed that the K40 display may be the most expensive straight screen in the industry. However, this device will also be on top as a “cost-effective device”.

We know that Redmi K30 Pro uses a pop-up full screen, a design that is not very common with 5G devices.  One of its down points is the use of a 60Hz refresh rate straight screen. Well, it appears that Redmi will not make the same mistake on the Redmi K40 series. The step-up from 60Hz to 120Hz is obviously a huge leap. The overall quality of this display will be top-notch, at least that’s what we expect.

In addition, the Redmi K40 series starting price of 2,999 yuan ($463) means that it has created a new low price for the Snapdragon 888 flagship phones. If there are no surprises, this device should be the cheapest Snapdragon 888 phone at launch.
