Transparent Laptop Display Raises Eyebrows

Lenovo has designed a laptop with a see-through display. But it's pretty transparently a gimmick. The company demonstrated the screen at the Mobile World Congress in Barcelona, an annual trade show where tech companies often unveil their latest ... ideas for portable gadgets. The technology behind a transparent display isn't particularly new. Generally they work by blocking or reflecting light to create an image, rather than emitting light as happens with traditional displays that are black when not in use or showing a "blank" image. The main use of the Lenovo "Project Crystal" display is for ... (view more)

New Smartphone Touchscreen Works When Wet

A high-end smartphone may solve one of the main problems with touchscreens. The OnePlus Ace 2 Pro works even in the rain or when the user has wet fingers. A touchscreen works by passing a very low-powered (and safe) electrical charge across the ... screen. When a finger touches the screen, the charge is diverted to run across the finger. The device can then see which part of the screen "lost" charge and thus where the finger pressed. (Source: iop.org ) This is why touchscreens don't work well with most gloves, which are made of various materials that work as insulators and don't conduct ... (view more)

Apple Considers Auto-Folding Phone

Apple has patented a folding smartphone that would automatically close up when dropped in an attempt to protect the screen. Several manufacturers of high-end smartphones already offer folding display screens. The idea is to allow a much larger ... screen size without being too bulky for a pocket. Analysts note one of the reasons Apple has yet to make a folding iPhone is fears that folding screens are more vulnerable to cracking, particularly when dropped. It's possible it may have intentionally waited for other manufacturers to lead the way so that it can then see such problems with a new ... (view more)

Android Malware Hides Behind Black Screen

A new variant of Android malware quite literally hides its activities. 'Octo' darkens the screen so that users can't see it stealing data. Researchers at Threat Fabric say the malware takes advantage of a built-in Android feature called ... "STREAM_SCREEN". It's not quite a live feed, but remotely transmits around one screenshot a second. (Source: threatfabric.com ) The scammers then misuse an accessibility feature in Android to remotely control the device. The stream screening lets them see what they are doing, despite not having physical access. Black Screen Disguise The sneakiest ... (view more)

Phone Screens Could Use Less Power

New technology could significantly reduce power that phone and other gadget screens consumer. It could also reduce the risk of screens being damaged by images "burning in." The technology is for OLED (organic light-emitting diode) screens which are ... now common in smartphones and other displays. In simple terms, the pixels in an OLED screen light themselves, whereas regular LED screens need a backlight behind the display. The main advantages are less power use and a thinner screen. The biggest drawback is a likely shorter lifespan, though that doesn't necessarily play a factor in devices such ... (view more)

Samsung Plans Triple-Screen Phone

Samsung has got approval for a patent on a phone with a double-folding mechanism. It would effectively be a tablet computer that fits in the pocket. The company already has a range of foldable phones with a single hinge, meaning a double-width ... screen. The new patent is for a double-hinge with one folding forward and one folding backward, a little like a "zed bed" mechanism. (Source: techradar.com ) The patent shows that the screens would be arranged so that an "ordinary" size screen was usable when the phone was fully folded. When the phone was unfolded, the entire display would be accessible ... (view more)

Recent Update Glitches Windows 'Alt-Tab' Shortcut

A recent Windows 10 update appears to have broken the Alt-Tab feature. Thankfully there's a simple fix that doesn't involve compromising security or performance. Holding down the Alt button and then hitting Tab is one of the more long-standing and ... useful Windows keyboard shortcuts. For those who've somehow missed out, it lets users quickly switch between open windows, including those not currently visible at the foreground. In later editions of Windows, including Windows 10, the shortcut displays a small image of every open windows showing its current content. That's useful when running two ... (view more)

Microsoft has explained the thinking behind some of the main changes in Windows 11. It's also tweaked a notification feature that could have been unnecessarily annoying. According to Microsoft it used a "new approach" in designing Windows 11. It ... suggests that the "new approach" was to give users what they wanted. The move to "human-centered design practices" involved giving users several pieces of paper marked with different operating system features and asking them to arrange them in order of importance. In an amazing coincidence, Microsoft says "the research matched up perfectly ... (view more)

Mobile Chrome Users Could Be Scammed

A tech expert has spotted a security risk in the mobile edition of Chrome. The way the exploit works means that scammers could make the browser appear to show a fake website address. This type of exploit would be particularly useful in a phishing ... scam, where hackers could develop a bogus website (such as a major banking site) to trick people into handing over personal information or passwords to sensitive data. James Fisher noted a potential problem with what's meant to be a useful measure in mobile Chrome. As the user scrolls down the page - which is much more likely to happen on a phone ... (view more)
