TI Officially Unveils 4K Home Theater DLP Chip
The new chip is said to be based on DLP Cinema technology and combines the fast switching speed of TI’s digital micro mirror device (DMD) with advanced image processing. It also provides manufacturers of home cinema front projectors with a 4K DMD microdisplay solution to compete against native or pixel-shifting 4K liquid crystal on silicon (LCoS) chip designs.
This latest 4K UHD DLP chipset, which TI said will be available to projector manufacturers this spring, is being produced as a single-chip projector architecture enabling high resolution and high brightness solutions at a price point that allows manufacturers to expand 4K UHD projection displays to a broad audience.
More on TI’s new home theater 4K UHD DLP chip after the jump:
The DLP 4K UHD solution uses the fast speed of the chip with advanced image processing to deliver more than 8 million pixels to the screen using just 4 million micro mirrors. TI said “each mirror is capable of switching over 9,000 times per second, creating two distinct and unique pixels on the screen during every frame to deliver full 4K UHD resolution.”
The DLP 4K UHD solution includes a high-performance 4K UHD imager with the fast switching speed of the DMD enabling each mirror to display two distinct and unique pixels on the screen during every frame, reducing blur and delivering full resolution. The inherent one-chip DLP system alignment enables the color integrity of the content to be maintained without blurriness between colors.
The 0.67-inch 4k DMD will enable affordable 4K UHD with a similar size to the DLP 0.65-inch 1080p chip. This will provide customers with access to more affordable 4K UHD solutions for homes and classrooms.
The technology is said to deliver strong ANSI contrast that brings out fine details in 4K UHD content, which will be discernible in large projection screen applications.
In addition, advanced image processing through proprietary algorithms will deliver sharp, high quality images with crisp and clear fine lines and details.
TI said the new 4K DLP chip can be used with multiple light sources including lamps, LEDs, and laser phosphor to enable projector manufacturers to create unique solutions for a variety of applications.
Early supporters of the new chip are expected to be manufacturers of value-priced home cinema projectors, such as Optoma and others.
“4K UHD comes to life when all of the details in the content are accurately displayed,” stated Dave Duncan, DLP Products business manager, Texas Instruments. “By giving customers the ability to incorporate a 4K UHD display chip that’s roughly the same size as our 1080p chip, this new solution from TI DLP Products can be a game changer for the industry.”
