In the optoelectronics, information, and communications industries, photocuring technology has made significant progress. Photoresists are also among the earliest photocurable products used, ranging from early polyvinyl cinnamate, cyclized rubber, and o-naphthoquinone azide to current deep-UV photoresists, electron beam photoresists, and nanoimprint photoresists used in large-scale integrated circuit manufacturing. In recent years, photoresists have also become increasingly popular in the production of flat-panel displays. Liquid crystal displays, plasma displays, and organic electroluminescent displays all rely on photoresists.

Optical fiber manufacturing is one area where photocuring technology has been successfully applied. After quartz is melt-drawn, it is immediately coated with UV fiber inner and outer coatings, and then with UV coloring inks to create optical fibers. Twelve different colored optical fibers are bonded together using UV tape coatings to form tapes, which are then assembled into optical cables. UV adhesives are used to connect the fibers.

Printed circuit board (PCB) manufacturing is another successful application of photocuring technology. Single-sided and flexible circuit board production requires UV etch-resist inks, UV solder mask inks, and UV character inks; double-sided and multi-layer circuit board production requires dry film etch-resist or photoimageable etch-resist inks, dry film solder mask or photoimageable solder mask inks, and UV character inks; build-up printed circuit boards require UV resin for photo-induced hole formation.

Plastic housings of various household appliances, such as televisions, refrigerators, air conditioners, and laptops, require UV wear-resistant coatings for protection. In mobile phone production, UV coatings, UV inks, and UV adhesives are used for protective coatings on plastic housings, keyboard production, keyboard surface printing, and assembly and bonding of multi-layer boards, LCD displays, and various components. Protective coatings and text and pattern printing on magnetic and IC cards, production of RFID chips and antennas, "three-proof" protective coatings on motherboards of important instruments and equipment, sealing, bonding, and securing electronic components, bonding, sealing, and securing coils, and manufacturing touch switches are all areas where various UV-curable products are highly effective.
