LG Display Begins Mass Production of 1Hz LTPO LCD Laptop Screens
▼ Summary
– LG Display has begun mass-producing laptop screens with a refresh rate that automatically adjusts between 1 Hz and 120 Hz.
– These screens, called Oxide 1Hz, switch to 1 Hz for static images like emails to conserve battery.
– They automatically increase to up to 120 Hz for dynamic content like movies, sports, or games.
– LG claims to be the first company to mass-produce displays with this specific 1–120 Hz adaptive range.
– The technology uses proprietary algorithms, panel designs, and special low-power-leakage oxide materials.
LG Display has initiated mass production of a new generation of laptop panels that can dynamically adjust their refresh rate from as low as 1 Hz up to 120 Hz. This adaptive refresh rate technology is designed to significantly extend battery life by intelligently matching the display’s power consumption to the content being viewed. The company claims it is the first to bring such a wide-ranging 1Hz to 120Hz LCD screen into mass production for laptops.
These displays, branded as Oxide 1Hz, function by automatically detecting on-screen activity. When a user is engaged with static content like reading emails, e-books, or documents, the panel switches to an ultra-low 1 Hz refresh rate to conserve power. For dynamic content such as streaming video, sports, or gaming, the display seamlessly ramps up to a high 120 Hz refresh rate for smooth motion. This dynamic switching happens automatically, requiring no user input.
The development required LG Display to create proprietary circuit algorithms and panel design technology. The company also engineered new materials and applied a specific oxide formulation to the display’s thin-film transistor. This specialized oxide is critical, as it features the lowest power leakage during the panel’s low-refresh-rate operations, which is fundamental to achieving the power savings.
