We report single and two-stacked WOLED. Two-stacked WOLED structure adopts fluorescent blue EML and phosphorescent (red+green) EML. Current efficiency, EQE and color coordinate of two-stacked WOLED are 54.5cd/A, 28.8% and CIExy (0.322, 0.345), respectively. Those of single WOLED are also 20cd/A, 10% and CIExy (0.29, 0.37), respectively. Dual-plate OLED Display (DOD) employing the single WOLED shows high aperture ratio up to 67% in 2-inch panel of which pixel size is equivalent to that of 32 inch Full HD.

We report the improved AMOLED with a-Si TFT backplane based on our unique structure. Our new structure is called Dual-plate OLED Display (DOD). It can also achieve not only higher uniformity of luminance in large-sized display due to low electrical resistance of common electrode but also wider viewing angle.

In this work, we provided a novel test method to verify the sealing materials for flexible LCD cell. The ultraviolet type curing sealing material with low process temperature was suitable for LCD cell assembly. We also proposed the sealing materials which passed 13200 times bending test within 20 mm curvature.

We developed a novel growth method of CNTs on metal substrate for device applications, deposited by a triode direct current plasma enhanced chemical vapor deposition (dc-PECVD). With resist-assisted patterning (RAP) method, we had grown CNTs on metal substrate, which were strongly bonded with metal substrate.

In this paper we describe solutions to address critical challenges in direct fabrication of amorphous silicon thin film transistor (TFTs) arrays for active matrix flexible displays. For all flexible substrates a manufacturable handling protocol in automated display-scale equipment is required. For metal foil substrates the principal challenges are planarization and electrical isolation, and management of stress (CTE mismatch) during TFT fabrication. For plastic substrates the principal challenge is dimensional instability management.

The 6- inch electrowetting display (EWD) can be successfully developed by ink jet printing (IJP) technique. Due to the drop-on-demand characteristic of IJP technology, colored oil can be precisely dosed into the unit pixel. Here, we present the active matrix EWD in this article. By adopting this technique to dose different colored oils, single layer Multi-color EWD without adopting color filter can be achieved in the future.

A novel single cell gap transflective liquid crystal display was developed. By using the ink jet printing technology, we fabricated a transflective liquid crystal display with the hybrid alignment in the reflective region and the homogeneous alignment in the transmission region. Compared with the traditional technologies, our technology provided the advantages of easy process, high yield, fast throughput, and less material usage. We also applied this technology to the 2.4 inch prototype. This panel could be implemented in the handheld product applications.

Carbon nanotube arrays were fabricated using micro molding in capillary (MIMIC) process. Patterns remained on the surface in the pattern complementary to that present in the mold. CNTs were selectively grown on the MIMIC patterned sites with a triode PECVD. And turn on field for $10\;{\mu}A/cm^2$ electron emission current was $2.2\;V/{\mu}m$ turn on field.
