SAN FRANCISCO NXP Semiconductors Monday (Feb. 12) announced a new technology said to improve mobile viewing experience by bringing "living-room quality" video images to cellular handsets and other mobile devices.
NXP (Eindhoven, the Netherlands) said its PNX4150 companion chip pairs the company's patented Mobile Pixel Plus (MPP) and Mobile Natural Motion (MNM) technologies to enable video sharpness, vivid and realistic colors, natural detail, smooth motion and enhanced contrast on mobile handset and personal media player (PMP) displays. Adaptive backlight control allows all of these features to be enjoyed with 40 percent lower power consumption of the display, according to the company.
Many people feel that video applications on mobile phones will never become ubiquitous in the U.S. because of the small screen size of most handsets. But NXP said the size of the screen is not as important as resolution quality.
"Too many people get hung up on screen size," said Rutton Ruttonsha, senior vice president of the NXP's mobile and personal business unit, in a statement. "It's not a matter of screen size. It's a matter of resolution. NXP has run focus groups. If you ask 10 people if they'd watch TV on a small screen, they'd say no. Then, if you actually give them a high-resolution screen running content, seven out of 10 said they would get one."
According to Vinita Jakhanwal, principal analyst for mobile displays at market research analyst iSuppli Corp. ( El Segundo, Calif.), "If visually intensive, interactive mobile applications, such as TV-on-mobile, streaming video, 3D gaming and location-based services are to reach mass acceptance and adoption among today's savvy consumers, handset and portable device OEMs must ensure they can deliver these groundbreaking applications with technology that provides both high quality and ease of usethis includes a high-definition, low-power mobile display."
In addition to MPP and MNM video-processing algorithms implemented in hardware, PNX4150 incorporates additional display-processing algorithms, including Adaptive Color Gamut Mapper (ACGM); Adaptive Contrast Booster (ACB); and Advanced Frame Mixer (AFM), NXP said. Because the video- and display-processing algorithms are implemented in hardware, they require less power than software equivalents, according to the company.
The PNX4150 companion chip sits between any baseband/application processor and cost-effective RAM-less display, NXP said. It accepts streaming video with input resolution up to QVGA, and can optionally up-sample the video to accommodate the full display size (for certain cases up to WVGA), according to the company.
"This device, in a very intelligent way, quadruples the amount of frames per second," said Kees Joosse, senior director of business development at NXP.
The PNX4150 companion chip will begin sampling in the second quarter, NXP said. The company is demonstrating the device this week at the 2007 3GSM World Congress in Barcelona, Spain.
