An anonymous reader quotes a report from Ars Technica, written by Andrew Cunningham: Back in 2013, Nvidia introduced a new technology called G-Sync to eliminate screen tearing and stuttering effects and reduce input lag when playing PC games. The company accomplished this by tying your display's refresh rate to the actual frame rate of the game you were playing, and similar variable refresh-rate (VRR) technology has become a mainstay even in budget monitors and TVs today. The issue for Nvidia is that G-Sync isn't what has been driving most of that adoption. G-Sync has always required extra dedicated hardware inside of displays, increasing the costs for both users and monitor manufacturers. The VRR technology in most low-end to mid-range screens these days is usually some version of the royalty-free AMD FreeSync or the similar VESA Adaptive-Sync standard, both of which provide G-Sync's most important features without requiring extra hardware. Nvidia more or less acknowledged that the free-to-use, cheap-to-implement VRR technologies had won in 2019 when it announced its "G-Sync Compatible" certification tier for FreeSync monitors. The list of G-Sync Compatible screens now vastly outnumbers the list of G-Sync and G-Sync Ultimate screens. Today, Nvidia is announcing a change that's meant to keep G-Sync alive as its own separate technology while eliminating the requirement for expensive additional hardware. Nvidia says it's partnering with chipmaker MediaTek to build G-Sync capabilities directly into scaler chips that MediaTek is creating for upcoming monitors. G-Sync modules ordinarily replace these scaler chips, but they're entirely separate boards with expensive FPGA chips and dedicated RAM. These new MediaTek scalers will support all the same features that current dedicated G-Sync modules do. Nvidia says that three G-Sync monitors with MediaTek scaler chips inside will launch "later this year": the Asus ROG Swift PG27AQNR, the Acer Predator XB273U F5, and the AOC AGON PRO AG276QSG2. These are all 27-inch 1440p displays with maximum refresh rates of 360 Hz.

Apple is building "a pricey tabletop home device" which uses "a thin robotic arm to move around a large screen," using actuators "to tilt the display up and down and make it spin 360 degree," according to Bloomberg's Mark Gurman. Citing "people with knowledge of the matter," Gurman writes that Apple assigned "several hundred people" to the project: The device is envisioned as a smart home command center, videoconferencing machine and remote-controlled home security tool, said the people... The project — codenamed J595 — was approved by Apple's executive team in 2022 but has started to formally ramp up in recent months, they said... Apple has now decided to prioritize the device's development and is aiming for a debut as early as 2026 or 2027, according to the people. The company is looking to get the price down to around $1,000. But with years to go before an expected release, the plans could theoretically change... The idea is for the tabletop product to be primarily controlled using the Siri digital assistant and upcoming features in Apple Intelligence. The device could respond to commands, such as "look at me," by repositioning the screen to focus on the person saying the words — say, during a video call. It also could understand different voices and adjust its focus accordingly. Current models in testing run a customized version of the iPad operating system... The company also is working on robots that move around the home and has discussed the idea of a humanoid version. Those projects are being led, in part, by Hanns Wolfram Tappeiner, a robotics expert who now has about 100 former car team engineers reporting to him. In a job listing published this month, Apple said it has a team "working to leverage and build upon groundbreaking machine learning robotics research, thereby enabling development of generalizable and reliable robot systems." The company said it's seeking experts with experience in "robot manipulation" and creating AI models for robot control. The article calls points out that Apple "still gets roughly half its revenue from the iPhone," and calls the robotics effort "one of a few avenues Apple is pursuing to generate new sources of revenue" — and to "capitalize" on its AI technology. (Apple is also working on both smart eyeglasses and augmented reality galsses.)

OLED panels have a number of advantages, including deep blacks, fast response times, and energy efficiency; most of these stemming from the fact that they do not need backlighting. However they also have drawbacks, as well, as trying to drive them to be as bright as a high-tier LCD will quickly wear out the organic material used. Researchers have been spending the past couple of decades developing ways to prolong the lifespans of OLED materials, and recently LG has put together a novel (if brute force) solution: halve the work by doubling the number of pixels. This is the basis of the company's new tandem OLED technology, which has recently gone into mass production.

The Tandem OLED technology introduced by LG Display uses two stacks of red, green, and blue (RGB) organic light-emitting layers, which are layered on top fo each other, essentially reducing how bright each layer needs to individually be in order to hit a specific cumulative brightness. By combining multiple OLED pixels running at a lower brightness, tandem OLED displays are intended to offer higher brightness and durability than traditional single panel OLED displays, reducing the wear on the organic materials in normal situations – and by extension, making it possible to crank up the brightness of the panels well beyond what a single panel could sustain without cooking itself. Overall, LG claims that tandem panels can hit over three-times the brightness of standard OLED panels.

The switch to tandem panels also comes with energy efficiency benefits, as the power consumption of OLED pixels is not linear with the output brightness.  According to LG, their tandem panels consume up to 40% less power. More interesting from the manufacturing side of matters, LG's tandem panel stack is 40% thinner (and 28%) lighter than existing OLED laptop screens, despite having to get a whole second layer of pixels in there.

In terms of specifications, the 13-inch tandem OLED panel feature a WQXGA+ (2880×1800) resolution and can cover 100% of the DCI-P3 color gamut. The panel is also certified to meet VESA's Display HDR True Black 500 requirements, which among other things, requires that it can hit 500 nits of brightness. And given that this tech is meant to go into tablets and laptops, it shouldn't come as any surprise that the display panel is also touch sensitive, as well.

"We will continue to strengthen the competitiveness of OLED products for IT applications and offer differentiated customer value based on distinctive strengths of Tandem OLED, such as long life, high brightness, and low power consumption," said Jae-Won Jang, Vice President and Head of the Medium Display Product Planning Division at LG Display.

Without any doubts, LG's Tandem OLED display panel looks impressive. The company is banking on it doing well in the high-end laptop and tablet markets, where manufacturers have been somewhat hesitant to embrace OLED displays due to power concerns. The technology has already been adopted by Apple for their most recent iPad Pro tablets, and now LG is making it available to a wider group of OEMs.

What remains to be seen is the technology's cost. Computer-grade OLED panels are already a more expensive  option, and this one ups the ante with two layers of OLED pixels. So it isn't a question of whether it will be reserved for premium, high-margin devices, but a matter of just how much it will add to the final price tag.

For now, LG Display does not disclose which PC OEMs are set to use its 13-inch Tandem OLED panel, though as the company is a supplier to virtually all of the PC OEMs, there's little doubt it should crop up in multiple laptops soon enough.
