In printed electronics, coating is a key process used not only in the fabrication of solar cell and organic light-emitting diodes but also in display devices. For this purpose, coating devices are designed with several unique characteristics. In particular, slot die coaters and inkjet coaters are advantageous in terms of high-quality morphology and a small dispensing area, respectively. This study proposes a slot die with a narrow-width coating as a fusion device derived from a slot die coater and an inkjet printer. This device is termed a micro-slot die and comprises a micro pump and a narrow-width slot. The device was designed and assembled with appropriate consideration of both dynamic and fluid motions. Consequently, the fabricated device achieves a high-quality coating suitable for application in the display industry. The proposed device is expected to be used in laboratory-scale research applications that require a minimal coating of ink.

在印刷电子产品中，涂层不仅是太阳能电池和有机发光二极管制造中的关键工艺，而且是显示设备中的关键工艺。为此，涂覆装置被设计成具有几个独特的特征。特别地，狭缝模头涂布机和喷墨涂布机分别在高质量的形态和小的分配面积方面是有利的。这项研究提出了一种具有窄幅涂层的狭缝模具，作为一种融合设备，它是由狭缝模具涂布机和喷墨打印机衍生而来的。该设备称为微槽模具，包括一个微泵和一个窄宽度的槽。该设备在设计和组装时会适当考虑动态和流体运动。因此，所制造的装置实现了适用于显示器行业的高质量涂层。
