PORTLAND, Ore. — Wearables is just one of the applications of Texas Instruments (TI's) digital light processing (DLP) 1080p pico-sized display measuring just 0.47 inches announced last fall. Today TI is announcing volume production of the chip plus a DLP LightCrafter Display 4710 Evaluation Module to help engineers get up and running quickly on applications ranging from digital signage to mobile projectors to screen-less TVs to control panels to interactive displays to wearables including Google-Glass-like head-mounted displays.
"We have engineers building applications that we never thought of," Frank Moizio, business unit manager for DLP told EE Times. "For instance, we have a stove maker working to project their control panel instead of using switches. Another is projecting scenes from other rooms onto the kitchen countertop to keep track of the children while cooking."
TI has also built up an ecosystem of third party developers to provide the needed items TI does not manufacturer, such as the optical engines that provide just the right amount of illumination onto the mirrored surface of the tilt-and-roll pixel (TRP) arrays that deflect just the right amount of red, green and blue light to form a 1080p image from the Pico 0.47-inch TRP Full-HD DLP.
"Together with our new LightCrafter Display 4710 Evaluation Module--which includes all the chips needed plus a light engine and optical lens--our ecosystem partners can supply everything you need to quickly evaluate the 0.47-inch TRP Full-HD DLP chip set and implement it in your design," Moizio told us.
TI's 1080p pico display evaluation module--LightCrafter Display 4710--comes with everything you need in a form factor that resembles a small portable projector.
The TRP technology make its pico-DLPs much more energy efficient than its previous designs, according to Moizio, allowing both battery powered an AC powered devices to use the same DLP depending on how much light they need to reflect--which can range from 5-to-10 lumens for heads-up-displays to as much as 1000 lumens for large screenless TVs.
"Wearables require much less lumens than a 50-inch screenless TV," Paul Rancuret, pico system engineer at TI told EE Times. "But the 0.47-inch TRP Full-HD DLP easily scales down to make a wearable at 1080p too."
The LightCrafter Display 4710 Evaluation Module also uses TI's Intellibright scene-by-scene analysis of images making realtime adaptive adjustments to brightness and contrast to optimize for lowest battery power, brightness, contrast or any combination of all three.

TI is also providing test data, optical engine specifications, schematics and block diagrams of all circuit boards along with design files. The designer can use that full infrastructure to build their device, from scratch to turn-key module. The full suite of offerings is available as free downloads..
The LightCrafter Display 4710 Evaluation Module takes its video input from a mini-HDMI with a USB port used for access to a graphical user interface (GUI) that manages features and peripherals, all available in the TI Store. You can also watch a video of how it works before you buy.
