DuPont Teijin Films™ (DTF) have developed engineered substrates specifically for the flexible electronics market. Teonex ®Q65 and Melinex ST506/504 are biaxially oriented crystalline polyesters with the option of planarised surfaces are emerging as competitive materials for the base substrate in OLED displays and active matrix backplanes. Given the demanding dimensional reproducibility requirements in the display applications, it is critical to control the several factors that can influence the film distortion to achieve the ultimate performance that can be achieved with the base substrate. This paper will discuss the impact of thermal stress, mechanical stress and the processing environment on dimensional reproducibility of polyester film and give examples of how this impacts on the film in device manufacture.
