  • 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.

  • Depending on the optical design method, a novel dual-mode transflective LCD with proper LC material and optical films was developed. The design increased the optical transmittance and the reflectivity of dual-mode transflective LCDs with the proper parameters of cell gap, alignment layer and optical films. These parameters were evaluated by computer simulation. The simulation results also revealed that the transmissive and reflective states presented similar performance in the transflective LCDs.

  • Two new cell structures for optical compensated bend were proposed. There are two groups of slit electrodes, which are driven by two different signals corresponding to the entire electrode as common electrode. The transmittance was enhanced without increasing the response time and light leakage. Compared with the traditional OCB mode, the increment of the transmittance of each kind is about 90% and 30%.

  • 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.

  • 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.

  • In this paper, the plastic organic thin-film transistors (OTFTs) with $32{\ast}32$ array are presented. Flexible organic light emitting diodes (OLEDs) operated by OTFTs are fabricated with a novel lamination method and the results are also presented. OTFT pixels defined by photolithography, and pentacene deposited by thermal evaporation. Fabrication method and the performances of green PHOLEDs with high efficiency, stability, and electrical performance are discussed.

  • Pentacene based TFT showed a degraded mobility and saturation current (Ion) after exposure to the high energy ultraviolet (UV). In this article, we optimize the thickness of UV resisted layer on OTFT to restrain the degradation from protect layer deposition and study the UV aging effect of pentacene based TFT. The OTFT deivce with UV resisted layer could keep over 50% mobility after suffered UV $10^3J$.

  • Carbon nanotubes backlight unit (CNT-BLU) that lightened by field emission was developed into practicability. According to our novel structure, AC mode circuit design and simple printing process, CNT-BLU could achieve 85% of uniformity, 8000 nits of brightness and low material and fabrication cost. Based on these performances, this new planar backlight technology has chances to proceed to mass production and has the potential to replace traditional backlight technology because of its good properties, like the simple processes, easy to large scale, low surface temperature, low power consumption, optical film-free and Hg-free, etc.
