The more common ones in China are Tianma Screen and BOE, which are generally used in thousand yuan machines. In fact, the quality control and pixels of BOE's high-end OLED screen are still very good, and the performance of Tianma's top LCD screen is also very good. It is rarely commercialized by major manufacturers on the strongest flagship models. Personally, I think it may just be a problem that has not been widely recognized or a problem of productivity.
Huawei is the largest mobile phone manufacturer in China, and mate series is its top flagship model, so it will definitely not be sloppy in choosing the material and screen of mobile phones. Huawei mate 10 screen is 5.9 inches with a resolution of 2560* 1440. The screen supplier JDI is made of TFT.
Huawei mate 10Pro is a full-screen design of 18:9, and the resolution of 6.0 inches is 2 160* 1080. Samsung AMOLED screen is considered to be the best organic light-emitting diode screen at present, with amazing production capacity, which can supply so many mobile phone manufacturers at the same time. But people often complain that its output is low and its price is expensive.
