LG Display starts mass-producing LTPO-like 1 Hz LCD displays for laptops
Dell XPS laptops will be the first to use the display tech that reaches up to 120 Hz.
LG Display is mass-producing laptop screens that automatically change their refresh rate from 1 Hz to up to 120 Hz, based on what’s on-screen, it announced this week. The display supplier said that it’s the first company to mass-produce these 1–120 Hz screens, which are supposed to boost battery life.
According to LG’s announcement, the LCD screens, which it’s calling Oxide 1Hz, will automatically use a 1 Hz refresh rate when detecting a static image on-screen and switch to up to 120 Hz when needed. Without providing more detail, LG said it created proprietary “circuit algorithms and panel design technology” and discovered “new materials and [applies] the oxide with the lowest power leakage during low-refresh-rate mode to the display’s thin-film transistor.”
In its announcement this week, LG said that “when performing tasks involving primarily still images—such as checking emails or reading e-books and research papers—the panel operates at the lowest refresh rate of 1 Hz. Conversely, it runs in high-refresh-rate mode at up to 120 Hz when streaming content such as movies or sports as well as playing games with frequent screen changes.
