Sharp Develops 'Two-Way Viewing-Angle' LCD

Filed under
Sci/Tech

At last, a way to end squabbles over which TV channel to watch - without buying a second set. Sharp Corp. has developed a liquid-crystal display that shows totally different images to people viewing the screen from the left and the right.

One person can be surfing the Internet, using the display as a PC screen, while another watches a downloaded movie or TV broadcast. It also works for watching two TV channels: One person can watch baseball while another watches a soap opera.

The "two-way viewing-angle LCD," announced by the Japanese consumer electronics maker Thursday, will go into mass production this month and will cost roughly twice as much as a standard display.
Sharp will offer the product for worldwide sale, but the Osaka-based company will also supply other manufacturers with the displays for various products expected later this year, said spokeswoman Miyuki Nakayama.

Sharp says the technology offers many possibilities.

It could be used in cars so drivers can look at a map while the passenger watches a movie. Or at a store, sales clerks and clients can view different data on the same display simultaneously.

Another possible use is for billboards that display two kinds of advertisements depending on where viewers stand. The display will also work in the regular way and show a single image to all viewers.

One catch is that the images overlap if viewers stand right in front of the screen. Moving a few inches to the left or right may be necessary for a clear view.

Another drawback is that users will have to work out a way to listen to the sounds coming from the different channels. One solution is for one viewer to use earphones.

The technology appears to derive from Sharp's three-dimensional LCD displays, which work by projecting slightly different images to the right and left eyes without the use of special glasses. Sharp has been selling 3D laptops for a few years, aiming them mainly at engineers, architects and other professionals.

A U.S. startup, Deep Light LLC, plans to launch its own monitors next year that can present several different images to different viewers in 3D without glasses.

Vulkan FOSS Adoptions

  • SDL 2.0.6 released, introduces Vulkan support
    The cross-platform development library has seen the release of its latest version. Quite a few exciting changes this time around, including support for Vulkan and more types of gamepads. SDL [Official Site] is something that has been used in quite a diverse array of projects and plenty of game ports that have made their way to Linux have taken advantage of it. The latest release has its fair share of general improvements but most noticeable is the implementation of Vulkan support. This hopefully will make it easier for developers to take advantage of the Vulkan API and help it gain more traction.
  • X.Org Foundation Has Become A Khronos Adopter
    The X.Org Foundation board announced during this week's XDC2017 summit that they have officially completed the paperwork to become a Khronos adopter.

Security: DHS on Potential Voting Machines Cracking, Joomla Patches Critical Flaw

  • DHS tells 21 states they were Russia hacking targets before 2016 election
  • 1. WikiLeaks, Russian edition: how it’s being viewed
    Russia has been investing heavily in a vision of cyberdemocracy that will link the public directly with government officials to increase official responsiveness. But it is also enforcing some of the toughest cybersecurity laws to empower law enforcement access to communications and ban technologies that could be used to evade surveillance. Could WikiLeaks put a check on Russia’s cyber regime? This week, the online activist group released the first of a promised series of document dumps on the nature and workings of Russia’s surveillance state. So far, the data has offered no bombshells. “It’s mostly technical stuff. It doesn’t contain any state contracts, or even a single mention of the FSB [security service], but there is some data here that’s worth publishing,” says Andrei Soldatov, coauthor of “The Red Web,” a history of the Soviet and Russian internet. But, he adds, “Anything that gets people talking about Russia's capabilities and actions in this area should be seen as a positive development.”
  • Joomla patches eight-year-old critical CMS bug
    Joomla has patched a critical bug which could be used to steal account information and fully compromise website domains. This week, the content management system (CMS) provider issued a security advisory detailing the flaw, which is found in the LDAP authentication plugin. Lightweight Directory Access Protocol (LDAP) is used by Joomla to access directories over TCP/IP. The plugin is integrated with the CMS. Joomla considers the bug a "medium" severity issue, but according to researchers from RIPS Technologies, the problem is closer to a critical status.
  • Joomla! 3.7.5 - Takeover in 20 Seconds with LDAP Injection
    With over 84 million downloads, Joomla! is one of the most popular content management systems in the World Wide Web. It powers about 3.3% of all websites’ content and articles. Our code analysis solution RIPS detected a previously unknown LDAP injection vulnerability in the login controller. This one vulnerability could allow remote attackers to leak the super user password with blind injection techniques and to fully take over any Joomla! <= 3.7.5 installation within seconds that uses LDAP for authentication. Joomla! has fixed the vulnerability in the latest version 3.8.

OpenSUSE fonts – The sleeping beauty guide

Pandora’s box of fonts is one of the many ailments of the distro world. As long as we do not have standards, and some rather strict ones at that, we will continue to suffer from bad fonts, bad contrast, bad ergonomics, and in general, settings that are not designed for sustained, prolonged use. It’s a shame, because humans actually use computers to interface with information, to READ text and interpret knowledge using the power of language. It’s the most critical element of the whole thing. OpenSUSE under-delivers on two fonts – anti-aliasing and hinting options that are less than ideal, and then it lacks the necessary font libraries to make a relevant, modern and pleasing desktop for general use. All of this can be easily solved if there’s more attention, love and passion for the end product. After all, don’t you want people to be spending a lot of time interacting, using and enjoying the distro? Hopefully, one day, all this will be ancient history. We will be able to choose any which system and never worry or wonder how our experience is going to be impacted by the choice of drivers, monitors, software frameworks, or even where we live. For the time being, if you intend on using openSUSE, this little guide should help you achieve a better, smoother, higher-quality rendering of fonts on the screen, allowing you to enjoy the truly neat Plasma desktop to the fullest. Oh, in the openSUSE review, I promised we would handle this, and handle it we did! Take care. Read more
