The History of HTPS precision technology

Technology and Craftsmanship for downsizing, Cooperate culture of creativity and challenge, World's first quartz watch Seiko Quartz Astron 35SQ, World's first color liquid crystal panel module for EVF, Micro Piezo, 3LCD, QMEMS, New Core Technology, Precision Mechatoronics Technology(=High-Precision processing technology+electronics technology), Epson's innovation mindset Compact, Compact, energy-saving and high-precision technologies

On Christmas night 1969 a revolutionary wristwatch was unveiled. The Seiko Quartz Astron 35SQ was the world's first quartz watch, a timepiece that was accurate to within 0.2 seconds per day, which, at that time, was considered ultra-accurate.
This groundbreaking quartz watch was developed by Epson, which was at the time known as Suwa Seikosha.
The precision-machining technology that Epson nurtured and refined during the development of this quartz watch was later applied to products such as printers and electronic components. Over time they became what Epson calls its "compact, energy-saving, and high-precision technologies," technologies that shrink the dimensions of objects, reduce the amount of power required for operation, and incrementally improve precision and accuracy. These technologies are still the strengths that underpin Epson's product development and manufacturing.

In 1977, Epson started to develop active-matrix LCD panels, and in 1982, introduced the "TV Watch." Later on, the direction of development shifted to polysilicon TFT systems, which promised to sweep away picture quality and size issues. In 1984, Epson commercialized world's first pocket-sized color television, the ET-10. Then, in June 1988, putting the unique advantages of polysilicon TFT technology to good use, Epson created the EVF Liquid Crystal Panel Module.
In January 1989, Epson announced the VPJ-700, the first Epson brand projector, in response to the need for large-screen images. This projector was developed using 3 high temperature polysilicon (HTPS) panels. Since then, HTPS has continued to lead the market as the key component of 3LCD projectors. In 2012, Epson shipped its 80 millionth HTPS panel.

The electronic view finder (EVF), on the other hand, did not see the same success as digital cameras shifted from analog to digital. Despite advances in camera features and resolution, several usability issues, such as difficulty focusing due to jagged pixels, have prevented the EVF from fully replacing the optical view finder (OVF).
Thus, using the high-resolution and miniaturization technologies of its HTPS panels, Epson re-entered the EVF market with the 2009 announcement of its "ULTIMICRON" line, which provides the ultimate in both resolution and vividness.

Going forward, Epson will continue to refine its HTPS technology and contribute to its customers' enjoyment of taking and viewing images.
