采用涂布和印花相结合的方法，在涤纶织物上实现了交流驱动电致发光器件。将PEDOT：PSS前电极用刀涂覆在织物上。所有其他层都是使用专门改装的三维打印机和三维打印软件进行数字打印的。评估了每种油墨的切片参数(线距、打印速度、打印图案)以及其他硬件参数和油墨粘度，以获得良好的打印效果。最终结果显示，所有被调查的参数之间存在复杂的相互作用。全数字印刷电致发光器件显示的发光强度为44 lx，但数字印刷和刀具涂层的组合对于发光层厚度更小的样品显示出高得多的高达128 lx的发光。
Alternating current–driven electroluminescent devices on polyester fabrics were realized using a combination of coating and printing. The PEDOT:PSS front electrode was coated onto the fabric using knife coating. All other layers were digitally printed using a specially modified three-dimensional printer and three-dimensional printing software. Slicing parameters (line distance, printing speed, printing pattern) as well as other hardware parameters and ink viscosity were evaluated for each ink to obtain a good print. Final results show a complex interaction of all investigated parameters. Fully digitally printed electroluminescent devices show a luminescence of 44 lx, but combinations of digital printing and knife coating show a much higher luminescence of up to 128 lx for samples with an even smaller luminous layer thickness.
