In USA, Epson introduces two EX Pro series projectors, delivering high brightness and advanced connectivity options, including built-in wireless projection (available on EX7235 Pro only) and Mobile High-Definition Link (MHL) support.

The EX7235 Pro and EX7230 Pro are designed for meeting rooms with ambient light and deliver WXGA resolution for widescreen HD presentations, 3000 lumens of color light output and 3000 lumens of white light output, and a simple setup suite to ensure flexible placement in virtually any room.

The EX7235 Pro includes a Wi-Fi module and a new quick connect on-screen QR code feature for easy wireless setup.

Researchers from the University of São Paulo and University of British Columbia reveal what one might describe as a "true" 3D display-- Spheree, a spherical device allowing one to admire and interact with 3D objects.

Described as the first "3D perspective-corrected interactive spherical scalable display," Spheree was revealed at the SIGGRAPH 2014 conference. In another mouthful from the team, it "arranges multiple blended and calibrated mini-projectors to transform a translucent globe into a high-resolution perspective-corrected 3D interactive display."

The researchers add Spheree does not have seams and blind spots, since it uses no special mirrors or lenses. Instead it uses an auto-calibration algorithm dubbed FastFusion to combine the resolution and brightness of the pico-projectors, while a basic webcam provides the positions of each projector's images on the globe.

LG announces the Curved UltraWide Monitor (model 34UC97), a 34-inch display the company the company claims is the first featuring a curved IPS panel with a 21:9 aspect ratio and 178-degree viewing angles.

The 34UC97 handles 4K/UHD resolutions (3440 x 1440), with Thunderbolt 2 connectivity allowing the daisy chaining of multiple monitors and audio via the combination of MAXX AUDIO and a built-in 7W tree speaker system.

It is set to make a first appearance at IFA 2014 together with other new LG monitors-- namely the Digital Cinema 4K Monitor (31MU97) and the Gaming Monitor (24GM77).

One of the alloys found in CDs and DVDs might be key for the thin and flexible displays of the future-- University of Oxford researcher discovered one can "draw" images on a thin layer of GST alloy sandwiched between two transparent electrode layers.

GST (aka Ge2Sb2Te5 or Germanium-Antimony-Tellurium) alloy is a phase change material (PCM), meaning it is able to change between two states with the application of heat, light or electricity. It finds use in rewritable CDs and DVDs, where laser pulses cause it to switch between amorphous and crystalline states.

"We didn't set out to invent a new kind of display," research leader Professor Harish Bhaskaran says. 'We were exploring the relationship between the electrical and optical properties of phase change materials and then had the idea of creating this GST "sandwich" made up of layers just a few nanometres thick. We found that not only were we able to create images in the stack but, to our surprise, thinner layers of GST actually gave us better contrast. We also discovered that altering the size of the bottom electrode layer enabled us to change the colour of the image."

According to the researchers tiny PCM stacks can be turned into "nano-pixels" measuring just 300 x 300 nanometers. One can electrically switch these on and off at will to create the building blocks of a high-resolution display technology.
