Why did Huawei join the OLED driver chip?

SMM Network News: recently, it is reported that Huawei has entered the driver chip market. Huawei consumer BG said it was not clear. However, industry chain sources told the reporter that Huawei began to set foot in the driver chip a long time ago. At present, the mobile phone OLED driver chip is in the streaming stage, and Huawei's flagship machine does not necessarily carry the self-developed OLED driver chip this year and next.

The source further pointed out that Huawei's entry into the OLED driver chip may be to improve the design and display of mobile phones, so as to enhance the differentiation competitiveness of flagship machines.

It is understood that Huawei has been sanctioned by the United States, and TSMC will not be able to produce Kirin chips for Huawei Haisi after September 15. Huawei's high-end smartphone P series and Mate series can only use chips designed and produced by other manufacturers, and cannot draw a gap with Xiaomi, OPPO, vivo and other competitors on chips.

Similarly, Huawei does not make OLED screens and has been at a disadvantage in its competition with Samsung Electronics. Every time Samsung Electronics S-series or Note series smartphones have better screen effect than Huawei P-series and Mate series smartphones, because Samsung Electronics' OLED screens are self-made and can introduce the most advanced screens into new products. For example, Samsung Electronics Note 20 Ultra 5G uses the world's leading LTPO OLED screen, which consumes less power and helps improve battery life.

With the mass production of OLED screens by panel manufacturers such as BOE, Vicino, Tianma and LG Display, Huawei has introduced flexible OLED screens to improve the appearance and screen share of smartphones, which can compete with Samsung Electronics's flagship phones. According to Ji Wei.com, at present, Huawei Hayes has a display technology research and development team of hundreds of people, which can constantly improve Huawei smartphone screen design and display performance and ensure product quality.

Even so, the screen performance of Huawei's flagship machine is still not as good as that of Samsung Electronics. For example, Huawei's flagship curved screen edge dimming function and 120Hz refresh rate screen launch time is half a beat slower than Samsung Electronics's. Because Huawei's OLED driver chips are supplied by Lianyong, Xinsi, etc., they may not be able to keep up with Huawei's demand in real time. But in the future, after Huawei adopts self-designed OLED driver chips, it can work closely with screen manufacturers to develop advanced display products, which will help to further improve the quality of Huawei's flagship machines, narrow the gap with Samsung Electronics, and compete with Xiaomi, OPPO, vivo and other differentiation.
