Touch Taiwan showcases touch panel full-fit optical materials

2018/08/27 | Science and Technology Corridor | Huang Zhiwei

With the continuous improvement of touch display technology, the demand for bonding materials and technology is also more diverse and improved. The professional glue solution provider Joe Yue Group, during the smart display and touch exhibition Touch Taiwan, exhibited touch panel full-fit optical materials and related bonding applications, in response to the industry's optical full-fit process Quality and yield requirements.

With the rapid spread of smart products, from portable handheld devices to large displays, outdoor billboards, and even car display and curved panels, users are constantly pursuing thin, thin, and better display effects, prompting major manufacturers to work hard. Technically strive to break through and provide an optimized screen rendering effect. At present, the current full-fitting technology can greatly reduce the reflection of light, reduce the loss of light, enhance the original brightness, and enhance the overall display effect; at the same time, the bonding strength of the full fit is also higher than that of the traditional word-of-mouth. The interference of the touch signal will also be reduced, thereby improving the smoothness of the touch function.

Qiao Yue said that in the full-bonding materials, it can be divided into two types: OCA (Optical Clear Adhesive) and Liquid Transparent Adhesive (LOCA) (Liquid Optical Clear Adhesive/ OCR, Optical Clear Resin). For the roll of FILM material, the latter is liquid optical glue. The reason why OCA is widely used is because the process speed is fast, and the requirements for yellowing are not so harsh in the early stage. The OCA of the acrylic system is low in cost, and then Strong, naturally become the best choice for consumer products. OCR is divided into acrylic and silicone, the former is mostly UV fast curing, the same applies to non-outdoor, less demanding weathering requirements The latter will be used in models with strict temperature and humidity tests, such as military flat panels.automotive panels and outdoor displays. Early silicone-based OCRs were heat-cured or cured at room temperature

In the past two years, the demand for outdoor display. vehicle. and military-controlled models has increased, and the test specifications of applied materials have become more stringent. In particular, the threshold for resistance to yellowing and high temperature and high humidity has become higher and higher. The weather resistance of the rubber system is also more favored. In order to balance the weather resistance of the products and the pursuit of production capacity, the manufacturers have introduced UV curing and Snap cure silicone OCRs, and through UV curing, the entire panel of the touch panel and the glass protective layer. The fit can be fully cured in just a few seconds, even without equipment; with Snap cure, it takes only 20 minutes to stand at room temperature to achieve full cure, providing the best fit for display products. solution

Qiao Yue Group is a professional rubber material solution provider, representing the new brand of Dow DuPont, the internationally renowned chemical material manufacturer, on the full-fit materials - DOWSIL OCR VE-2003 UV optical curing silicone, in Korea Taiwan, Japan and Japan have been recognized by well-known brand factories and first-line foundries, and the original factory has continuously improved product characteristics to be closer to customer requirements. In terms of product layout, we will introduce different features such as Snap cure and two-component UV curing, in order to meet the high process yield requirements of many customers in the pursuit of optical full-fit process. .
