Looking back at the smartphone market in 2023, it is clear that the trend of LTPO replacing LTPS has taken hold in the industry. Especially since the second half of 2023, the 8T1C LTPO screen has been applied in domestic high-end flagship models. Industry experts generally believe that 8T1C LTPO is poised to become the mainstream solution for flagship smartphones in the future. Some even proclaim, "Without 8T1C LTPO, you can't call it a top-tier screen." 8T1C LTPO serves as the future direction and the standard configuration of flagship projects.

What is 8T1C LTPO?

8T1C is a new type of pixel driving circuit that achieves a higher reset frequency for the anode and driving transistor TFT. Initially, LTPO technology utilized the traditional 7T1C pixel circuit. On such a basis, 8T1C is added with a driver transistor TFT reset driver circuit. This innovation means each pixel on a screen of the same size requires an additional driving circuit, significantly increasing both design complexity and cost.

Why is the 8T1C LTPO screen favored by high-end flagships? What are its technical advantages?

Superior display effect

For users, the hallmark of a great screen lies in its display performance. As an upgrade to the LTPO driving pixel circuit, 8T1C first significantly enhances the visual experience.

In terms of display uniformity, based on the traditional 7T1C, the 8T1C circuit's added reset driver allows for three periodic compensation and reset actions (at a base frequency of 120 Hz), improving the pixel display frequency from 120 Hz to 360 Hz. This results in superior pixel consistency, enabling clearer and more transparent display quality. For example, whether browsing TikTok or Little Red Book, the 8T1C minimizes the impact of one frame on the next, delivering a smoother visual experience.

Smoother image

The frequency-switching capability of 8T1C has been upgraded from 120 Hz in 7T1C to 360 Hz. Thanks to uniform 360 Hz reset and compensation, the screen transitions faster and more seamlessly while significantly reducing screen flicker. Whether using WeChat, TikTok, Toutiao, or gaming, this delivers a smoother image and better operation experience.

Lower power consumption

LTPO is renowned for its low power consumption benefits brought by adaptive regulation. Nowadays, with a long battery lifespan increasingly becoming a must-have feature, 8T1C LTPO takes power efficiency to the next level.

First, the 8T1C LTPO supports a wider range of driving frequencies, enabled by its multi-pulse reset driving circuit. This allows for a variety of frequencies such as 1 Hz, 30 Hz, 40 Hz, 60 Hz, 72 Hz, 90 Hz, and 120 Hz, each tailored to specific application scenarios. Through precise and efficient frequency management, power consumption is minimized without compromising performance. Additionally, the 8T1C LTPO achieves direct frequency switching without the need for transitional frames, further reducing power consumption.

Moreover, 8T1C LTPO ensures power-saving benefits and flicker effects, enabling displays to operate at 1 Hz across all scenarios. It allows for faster, flicker-free transitions to 1 Hz and is key to achieving true global AOD at 1 Hz. Meanwhile, it excels in overall eye protection performance. 

With its exceptional display quality, smoother transitions, lower power consumption, and extended battery life, the 8T1C LTPO screen has rightly earned its place as a favorite among high-end flagship models.
