TI to aim DLP display controller at smart glasses
Texas Instruments has reduced the size of its digital light projector (DLP) controller by 90% for more compact 4K UltraHD projectors, and is aiming at smart glasses.
The TI DLPC8445 DLP display controller is the first in a family and measures 9 x 9mm and supports submillisecond display latency and frame rates up to 240Hz for displays up to 100in.
The controller can be combined with TI’s compatible digital micromirror device (DMD), the DLP472TP, and power-management integrated circuit (PMIC) with LED driver, the DLPA3085 for high end televisions and gaming monitors in the form of a compact projector.
The DLPC8445 controller is the first device in the family. Future chipsets using the new controller technology will feature DMDs of different sizes and resolutions to address new trends in display applications such as augmented reality glasses. It is also the first DLP controller designed for laser-illuminated battery-powered projectors.
All previous DLP display controllers have used a double-frame buffer architecture, which adds a one-frame delay and higher power consumption. The DLPC8445 DLP display controller uses a new frame buffer architecture that enables significantly reduced display latency.
When combined with the fast switching speed of the digital micromirror device (DMD), the DLPC8445 can enable display latency less than 1ms when measured at the corner of the image from which new frame data enters.
“Immersive display entertainment is now sought out by everyday consumers, not just movie enthusiasts and gamers,” said Jeff Marsh, vice president and general manager of DLP Products at TI. “Where consumers once needed a big TV or monitor for a crisp and clear display, they can now use a lifestyle or gaming projector and transform a wall into the screen size of their choosing with 4K UHD quality. Our new controller is the latest example of how TI DLP technology is helping engineers develop epic displays for entertainment that can be taken anywhere.”
This is the first Integration of variable refresh rate (VRR) support to improve displays for gamers by allowing designers to easily sync frame rates and eliminate lagging, image tearing and stuttering. Advanced image-correction capabilities dynamically adjust for surface imperfections, making it possible for consumers to conveniently take their gaming and viewing experience anywhere.
Preproduction quantities of the DLPC8445 controller, DLP472TP DMD and DLPA3085 PMIC are available for purchase now on TI.com. Pricing for the new DLPC8445 controller starts at US$60 in 1,000-unit quantities.
