Cutting OLED Smartphone Displays with a UV Femtosecond Laser
In the last few years OLED (organic light-emitting diode) technology has revolutionized the display industry. As the technology advances and OLED displays continuously improve in contrast, resolution, color range, lifetime and power efficiency, older display technologies are rapidly being supplanted in devices ranging from TVs and laptops to smartphones and wearables. Moreover, as the demand for thinner, flexible, foldable and transparent screens continues, so too does the quest for new manufacturing tools. Because of the high resolution and sensitive circuitry in OLED displays, a key challenge in their manufacture is achieving narrow kerf widths with negligible heat-affected zones (HAZ).
