June 21, 2007, Chunan, Taiwan--TPO Displays is introducing Self-Refreshing-Pixel (SRP)-maximum intensity projection (MIP) technology, enabling mobile displays to achieve low-power consumption and high transmittance aperture at the same time. The technology offers higher luminance without affecting usage time.

In today's consumer market, mobile liquid crystal display (LCD) applications providers often need to choose between longer battery performance via lower power consumption, or stronger display brightness through a higher transmittance aperture. To overcome this challenge, TPO has developed a novel SRP-MIP technology on a 1.36-inch QQVGA LCD that provides lower power consumption with a high transmittance aperture, improving mobile display performance. Mobile phones equipped with TPO's SRP-MIP sub-displays can extend the battery life two days longer than mobile phones with conventional displays.

TPO based its proprietary SRP-MIP technology on DRAM-MIP technology for a low temperature polysilicon (LTPS) process. The key to TPO's SRP-MIP technology is in its refresh function, which is fully integrated within the pixel, thereby eliminating the transfer of data between the pixel and outside circuit. This process, achievable only on LTPS panels, dramatically reduces the number of voltage transitions applied to the column bus lines and common electrode for the frame refresh.

"Our SRP-MIP technology provides our clients a module that not only offers longer battery life, but also features high display brightness," said Bart Jeroen van der Bent, TPO Displays telecom product marketing director. "We anticipate demand in the sub-display panel market from tier-1 mobile device manufacturers."
