The car central control screen fitting, which needs to deal with the high requirements of large screen size, environmental weather resistance, display imaging clarity, etc., has been transferred from the traditional “frame stick” process to the “full fit” process.The organic silicon liquid optical adhesive produced by BTL is a kind of water adhesive specially designed for the full-fitting of automobile central control large screen. Compared with the “frame-paste technology”, it achieves better air tightness, ultra-thin appearance design and excellent screen display effect, while compared with the “acrylic all-adhesive water adhesive”, it perfectly solves various problems such as poor reliability, poor screen side fixation, MURA phenomenon and water splash phenomenon, making it the best choice for the central control screen fitting of automobiles at present.
