Progress in optical adhesive and lamination process of touch screen in 3C products

Abstract

Compared with the traditional keyboard and mouse input method, touch screen technique has high convenience for users. With the development of technology, touch screen is widely application in various electronic products because of their high transmittance, clear images, and convenient operation. This review mainly introduces the optical clear adhesive (OCA), liquid optical clear adhesive (LOCA), and the most commonly used LOCA ultra violet (UV)curable adhesives. Preparation and performance of UV-curable adhesives are deeply explored. The structure of touch screen, such as one glass solution (OGS), on-cell and in-cell is discussed. Moreover, lamination process includes full lamination and non-full lamination is also discussed. This review introduces the alignment technique comprise mechanical alignment technique and non-mechanical alignment technique (such as machine vision) and laminating equipment. The recent development and existing problems with the touch screen lamination process are discussed. Furthermore, this review describes the latest developments in the adhesive of touch screen lamination process and predicts possible future development trends, which could provide references for subsequent research work.

Progress in Active Infrared Imaging for Defect Detection in the Renewable and Electronic Industries

“…The advancement of technology has led to increasingly stringent requirements for the quality of electronic components [11]. This chapter provides an overview of the application of IRT in electronic component defect detection from four aspects.…”

“…The electronics industry, stemming from the advancement and application of electronic science and technology, is not only one of the pillar industries of the national economy, but also an emerging science and technology development industry. In integrated circuits, for example, the electronic circuits of printed circuit boards (PCBs) are widely made [10,11], and these contain a high density of electronic components in the board power supply and many electronic connections, which are potential manufacturing defects. And the identification and localization of these defects are critical to the error-free performance of PCBs.…”

Study of Heat Transfer Strategy of Metal Heating/Conduction Plates for Energy Efficiency of Large-Sized Automotive Glass Molding Process

“…As a major contributor to the world economy, China is the world's largest producer and consumer of coal and, naturally, the world's largest emitter of carbon [25][26][27][28]. Therefore, improving the efficiency of energy use and reducing carbon emissions are necessary parts of our production and processing [29][30][31]. During the process of forming large-scale automotive instrument glass, the heating apparatus requires electrical energy, the main source of which is coal used for electricity generation.…”

Inserting auxeticity into graphene oxide via bottom-up strategy

“…[42][43][44] In addition, due to the ultrawide bandgap of α-BK-C 2 O, its dielectric constant (calculated to be ∼8.54) is ∼50% higher than that of diamond (∼5.87), which will garner increasing attention in the fields of photodetectors 45 and touch screens. 46 Furthermore, α-BK-C 2 O would maintain its configuration over 2000 K, thereby guaranteeing extremely high thermodynamic stability. Owing to its excellent dielectrics, C 2 O-based materials in the α-family could replace diamond and have considerable wide-ranging applications.…”
