AU Optronics has taken the wrapping off the world’s highest resolution, 5.7-inch AMOLED touchscreen. How high is the pixel count? It’s 2,560 x 1,440 pixels, or 1440p, which is widely expected to be the next big thing in smartphone screens.

It’s not the first of its type we’ve seen. Both LG Display and Japan Display have shown early prototype versions of 1440p screens, but this is the first time an AMOLED panel with such a high resolution has been produced. Many of you will already be aware of the benefits AMOLED brings, such as a sharper image and brighter colors, but it also takes less energy to power, helping the battery inside your phone last longer.

AU Optronics says the super thin panel measures just 0.57mm thick, which is less than half the thickness of Japan Display’s 5.4-inch, 1440p screen announced last year. The large size and impressive resolution returns a very high pixel density of 513ppi, and the panel uses In-cell touch technology for the best possible sensitivity. The company has also introduced a non-AMOLED, 6-inch screen with a 1440p resolution.

Interestingly, the press release also states AU Optronics is looking at making screens for smartwatches, and confirms it has a 1.6-inch AMOLED screen in development. We’ve recently seen how good an AMOLED screen can look on a wrist-worn device, thanks to the beautiful Samsung Gear Fit. Samsung also used a 1.6-inch AMOLED screen on the original Galaxy Gear.

AU Optronics, like LG Display and Japan Display, usually operates behind the scenes, and is unlikely to be a name many recognize. However, it is a former Apple supplier, and has also collaborated with Sony on some of its OLED televisions. So-called Quad HD screens are expected to be quite a hit later this year, following the announcement of hardware such as the Oppo Find 7, and we could be introduced to the first mainstream Quad HD phone – potentially the LG G3 – next month, if the rumors are correct.

Sadly, AU Optronics doesn’t mention whether the new AMOLED screen will find its way on to a smartphone any time soon.

Ray-Ban Meta glasses get ‘major’ update with minor feature

The Ray-Ban Meta smart glasses next to a pool.

Someone maybe should tell Meta that point releases — software updates that move things along, but maybe don’t justify entire whole-number increases in the version scheme — are a thing. But here we are, and the Ray-Ban Meta glasses have received an update to Version 8.0, a little less than seven months since things really kicked off with Version 2.0.

What changes from Version 7.0 to Version 8.0? You can now share photos to your Facebook story without having to touch anything. It’s gone hands-free. You’ll need to go into the Meta View app and connect your Facebook account, but otherwise, you’re free to tell your glasses to share whatever it is you’re looking at that simply must be shared right that second. So not quite as big a deal as when the Ray-Ban Meta tripled their recording time.

One of the fastest internet speeds you can get, and the fastest speed that Verizon offers, this is the sort of subscription you should grab if all the members of your family are essentially watching 4K content all the time. It's also great for those who want to host their own media server to share with friends or family while not impacting anybody else in the home. You also get a lot of great freebies included here, such as a $400 savings on Samsung home appliances and a free $200 Verizon gift card.

Apple Watch Series 10 now expected to get a major new health feature

A person checking the fitness data on an Apple Watch Series 9.

Apple is expected to announce the Apple Watch Series 10 and Apple Watch Ultra 3 at Monday's iPhone 16 event. We've heard little beyond hardware speculation about these watches — untilnow. Today, Bloomberg's Mark Gurman reported that both watches may have a sleep apnea detection feature. If accurate, it would be the first time an Apple wearable device has offered this functionality.

Those suffering from sleep apnea experience repeated breathing stops and starts during sleep. This leads to poor sleep quality and a range of health problems. Unfortunately, it's hard for a person actually to know that they are suffering from this disorder. Detecting sleep apnea makes it much easier for health care providers to diagnose and determine the best course of treatment.
