LOS ANGELES—We’ve heard of 1Hz laptop screens to save on battery life. But Chinese display manufacturer TCL CSOT is going 100x further with a 0.01Hz laptop panel.
At SID Display Week here, the company showed off the technology in a 14-inch laptop with a 1,920-by-1,200-resolution screen. The display stands out by featuring a refresh rate that can hit one frame per 100 seconds, rather than the usual one frame per second of an 1HZ panel.

TCL CSOT’s technology goes even further by using 12 zones across the screen that can jump from 0.01Hz to a regular 120Hz. This means a user could view a video in one part of the screen at normal refresh rates, but the rest of the display would remain at 0.01Hz, thus saving energy.
TCL CSOT estimates that the lower refresh rate can extend video playback time on a laptop by over an hour. The screen is an LCD that uses the company’s own backplane technology, known as “Oxide TFT.” LG has been developing a similar concept, but it doesn't appear to feature the region-level variable refresh rate across parts of the screen.

TCL CSOT, a subsidiary under TCL Technology Group, told us the technology is production-ready. But the company needs to work with software and chip vendors, including Microsoft, Intel, and AMD, to fully enable the refresh rate switching. So it's not clear if we'll see the technology in a laptop anytime soon.

The monitor is also thin, like a tablet, especially when folded. The company plans to mass-produce the trifold monitor next year, though pricing remains unclear.
Although it's overkill, the company also improved on its 8K 1,000Hz ultra-wide gaming monitor, which debuted at last year’s Display Week. The monitor can now hit a refresh rate of 1,200Hz.
