OGS faces a critical threshold, and the launch of the iPhone 5 is imminent, which also makes the touch panel industry more anxious, because Apple is preparing to use In-cell Touch panels with integrated touch functions this time. If this move is mature, it will allow the touch panel industry Throw away your rice bowl. The general manager of the invention, Li Xiangyu, said in the lecture of CTIMES Technology Forum "Patent Impact Analysis of Capacitive In-cell Touch Technology" that there are still many bottlenecks to be overcome in In-cell Touch technology. In contrast, single-chip OGS Technology development is relatively mature, and it still has a competitive advantage at this stage. OGS process of first strengthening and then cutting Compared with the traditional G / G type touch panel, OGS saves 30% of the cost and the light transmittance can be increased. In addition, without changing the LCD panel process, it can be produced in a small amount and diversely, so it has become the development trend of the touch panel industry. However, Li Xiangyu quoted Chen Hengyao, the chief technical officer of Chen Hong, and pointed out that the technical barriers of the OGS solution are still high, and the problems faced include the chain reaction of the industrial chain such as touch sensitivity, panel hardness, and transparency. Zhang Hengyao said that the first problem encountered in the current OGS program is to do chemical strengthening before cutting, or cutting first and then strengthening. The current whole piece of strengthened glass is more effective in the yellow light process, and the problem faced by the panel industry is that if the cut strengthened glass is used for OGS, it will inevitably encounter problems in the yellow light process, production efficiency and equipment. Will be affected. The second problem is that in touch sensitivity, there is almost no control IC factory that can solve the physical noise problem of LCD and power supply. Therefore, whether the technology of the IC design company can cooperate can become the mainstream of OGS. The key to the application. Another problem worth noting is that although OGS relatively reduces the single piece of glass, it will still be covered with a layer of anti-explosion film, but the anti-explosion film is prone to yellowing and uneven yield. OGS may move towards the Full LaminaTIon process. If the use of explosion-proof membrane is omitted, it will undoubtedly benefit the full lamination plant directly. Li Xiangyu also cited the analysis of Professor Lin Yanrui of the Chinese University of Science and Technology and pointed out that many touch panel factories are now accustomed to using optical tape (OCA) bonding technology with high production efficiency and easy thickness uniformity, but this technology is in When bonding, it is easy to generate bubbles to increase the defect rate, and tiny bubbles that cannot be found during bonding may also expand with time. Only the purchase of expensive vacuum equipment can have the opportunity to suppress the generation of bubbles. In addition to the air bubble problem that will affect the OGS yield, optical tape cannot be reworked, so most defective products can only be scrapped, resulting in inefficient production and increased pressure on the cost of the bonding plant. The more ideal way is to use liquid optical adhesive bonding technology, but it is more difficult to adjust the thickness and maintain the parallelism, and when bonding, the liquid optical adhesive may also exceed the bonding range due to pressure overflow It must be solved by manual wiping, resulting in the problem of low production efficiency. In response to this challenge, Chen Hong has developed a border around the substrate, and then cured the four sides, so that the liquid optical adhesive will not overflow when pressurized, and through the automatic bonding equipment of liquid optical adhesive, it can accurately Set the amount of glue, spreading speed, flatness and other parameters to solve the problems of residual bubbles, glue overflow, uneven coating and entrained dust during lamination. Overall, although OGS is regarded as the unique technology of the touch industry to consolidate the site, Li Xiangyu pointed out that almost no one manufacturer can propose a solution to solve the problems of hardness, touch sensitivity, and transparency. Therefore, the real evolution of OGS that can be adopted by mid-to-high-end touch products will take some time.
