BOE’s touch technology---having high tech at your fingertips
Publish time:2015-01-05

    A host of artificial intelligence products such as voice assistants are doing increasingly well in getting what people want. More advanced human-computer interaction (HCI), however, require such smart products to be as reliable as friends and make timely, accurate responses to our actions. The advance from single-touch to multi-touch technology has paved the way for the advent of the HCI era. The mainstream of touchscreen
technology in the next five years will be Add-On, One Glass Solution (OGS), On-Cell, and In-Cell. The latter three, in particular, will see their
market shares keep growing due to their strengths in thickness, cost and integration.
    OGS is a touch technology that enables integrated touch. It means that the touch sensor and protective glass are combined into one. Given
that, OGS touch panels are less costly and lighter, and enables better transmittance and touch sensitivity. However, the one problem with the
technology is that the strength of glass needs to be great since the single-sheet glass is both a strong and safe cover and a touch sensor. To
address the problem, BOE adopts laser cutting technology and isotropic etching process in its OGS touch panel production line in Hefei, which
makes the world’s largest touch panels. As for in-cell technology, a part of or the entire touch portion is placed in the “cell” so an integrated
structure is adopted for both display and touch control. In-cell displays are highly integrated, thinner, and touch sensitive. As in-cell technology
develops, users will surely experience the natural, direct and instant human-computer interaction. For example, BOE’s first 5.0-inch in-cell mobile
phone panel has a bezel of only 1.2mm, two-thirds that of iPhone 5s. Besides, its 5.5-inch FHD in-cell mobile phone panel, the first of its kind in the world, features a pixel density of 403PPI and ultra high contrast of 1500:1, and its display and touch control functions are highly integrated.
Thanks to ultra low color shift, the panel displays images finer and more precisely.
    In addition, touch panels are used not only in smart phones and tablets but also in various electronic products with LCD displays, such as
notebooks, all-in-one PCs, monitors, and public displays.
