ALP is the proud innovator of TRIOLCD
® ALP has been very encouraged to receive all the positive responses we have from our customers regarding this line of products and to see that our innovative enhancement approach has stirred up some “common interests in the industry since its original introduction. ALP has teamed up with RayShine Photonics Corp. in Taiwan since 2004 to expand our manufacturing capacity and R&D resources. As a part of ALP/RSP continuous combined efforts and commitments to the display industry, we have recently advanced our innovative LCD enhancement technology to include the integration of a resistive touch panel, RT-TRIOLCD™ series. RT-TRIOLCD™is a resistive touch panel integrated display system designed with similar concept of Trio process - the Transmissive and reflective illuminations optimization process, which is again a result of our R&D effort in understanding the optical properties of the parts involved in the integration. Integrated with a resistive touch screen of ~75% transmission, RT-TRIOLCD™ has the similar optical properties to TRIOLCD® with very low surface reflectance, Fig. 1, and can also utilize the transmitted ambient light as its reflective illumination. A 15" notebook screen with various integration areas under indoor and outdoor environments are shown in Figs. 2, 3, and 4, where A is a regular resistive touch panel integrated screen area, B is a TRIOLCD® integrated screen area, and C is a RT-TRIOLCD™ integrated screen area. In an Indoor environment all areas are viewable. However, in outdoors with shady or direct sunlight conditions, only areas B and C integrated with TRIOLCD® and RT-TRIOLCD™ are readable, Figs. 3 and 4. Further shown in Fig. 5, a 15" notebook TRIOLCD® on the left-hand side and a 12.1" RT-TRIOLCD™ of the monitor on the right-hand are simply clear in both the direct sunlight and shady areas.
