After LG and Hyundai Philips announced a new product series of polarized 3D LCDs. Still they will continue to offer active stereo. The advantage of polarized displays, in their opinion are the cheap glasses. Polarized displays will become available starting in two product series: First the 7000er series and the 50″ “Gold variant” of the 21:9 Cinema Display. In the 7000er series the 42″ 42-PFL7607K will be available starting in May followed by displays in the range of 32″ to 55″ between June and August.
A Laser Phosphor Display works in many ways like an old CRT Monitor. Instead of an electromagnet it uses a solid-state laser diode to energize a pattern of phosphors layered in a rigid glass or polymer structure. When excited by the Laser Engine, the Phosphor Panel emits red, green, or blue pixels extremely close to its surface, with no image filtering to waste power. This emissive display technology has the highest possible viewing angle (typically twice that of LCDs or LEDs) with no pixel burn-in or failure. The display may be modified with special coatings or substrates for specific viewing needs.
The company prysm now has several display systems based on that technology available. Most of them are modular and can be set up like classic video cubes.
Electrovibration could make for a better sensory experience on a smooth touch surface.
Touch screens are ubiquitous today. But a common complaint is that the smooth surface just doesn’t feel as good to use as a physical keypad. While some touch-screen devices use mechanical vibrations to enhance users’ experiences of virtual keypads, the approach isn’t widely used, mainly because mechanical vibrations are difficult to implement well, and they often make the entire device buzz in your hand, instead of just a particular spot on the screen.
Now, engineers from three different groups are proposing a type of tactile feedback that they believe will be more popular than mechanical buzzing. Called electrovibration, the technique uses electrical charges to simulate the feeling of localized vibration and friction, providing touch-screen textures that are impossible to simulate using mechanical actuators.

Some use cases for pico projectors.
One of the few available polarized LCD 3D Displays is the LG 47LD950. As of today the lowest internet price is ~1.000 Euro.
Hyundai has also some polarized LCDs available pdf but the 46″ sized displays internet price is now arround 9.200 Euro.
The last polarized display I found is the JVC GD-463D10. The internet price is arround 5.200 Euro.
What’s the reason for the huge price difference? I don’t know.
If this proves as promising as the demos look the new Microsoft Surface II means doomsday for a lot of other multi-touch products out there, especially for the DI kind. Like the old projection based Surface they need a lot of space behind the screen. The new Surface uses a LCD with infrared sensitive pixels developed by Samsung and is only 4 inches thick. The raw image from the device, as you can see in the demo video, looks pretty much the same as from a camera in a DI touch. But as the diffusion layer of the back projection screen is missing it is pretty sharp. This allows to use the display as a “scanner” and should extend it usability for object and tag recognition.
