12.2: Invited Paper: Colloidal Quantum Rods and Wells for Lighting and Lasing Applications
Authors: She Chunxing , Fedin Igor , Boles Michael A. , Dolzhnikov Dmitriy S. , Schaller Richard D. , Pelton Matthew , Talapin Dmitri V. 
Published: July 2014

AbstractColloidal semiconductor nanocrystals, also known as “quantum dots” (QDs), represent an example of a disruptive technology for display and lighting applications. Their high luminescence efficiency and tunable, narrow emission are nearly ideal for achieving saturated colors and enriching the display or TV color gamut. Our contribution will discuss the next generation of inorganic nanostructures with electronic structure optimized for achieving emission characteristics beyond traditional near‐spherical QDs. For example, nano‐heterostructures with spherical CdSe QDs epitaxially integrated into CdS quantum rods combine high luminescence efficiency with giant extinction coefficients, large Stokes shifts, and linearly polarized emission. Such a set of characteristics can be ideal for LCD backlighting. The other class of emitters includes colloidal quantum wells (QWs) whose ensemble luminescence is significantly narrower than emission spectra of the best QD samples. Moreover, we show that colloidal QWs produce amplified spontaneous emission (ASE) with pump‐fluence thresholds as low as 6 μJ/cm2 and gain as high as 600 cm−1, on par with the best values for any solution‐processed material.

AbstractExo‐electron currents emitted from MgO Nano‐powders sprayed on MgO thin film were measured using a highly‐sensitive and fast‐responding measuring apparatus. The results indicated that the short statistical delay with the MgO nano‐powders is mainly due to increased exo‐electron currents from MgO nano‐powders.

Authors: Lee Jae‐Youl , Pae Hansu , Lee Kil‐Hoon , Lee Dongmyung , Lim Jung‐Pil , Tak Wonho , Choi Yoonkyung , Hwang Gyoocheol 
Published: July 2014

AbstractThis paper has reviewed several key features of intra‐panel interfaces for high‐resolution tablet personal computers to satisfy essential requirements such as high‐speed operation, low power consumption, and low radio frequency interference (RFI). The clock‐embedding scheme and the type of transmitter driver affect maximum data rate and minimum power consumption. Power saving can be achieved through physical layer implementation as well as protocol layer design by optimizing current consumption of column drivers. RFI from signal channels on PCB can be effectively suppressed by modified data scrambling scheme with low toggle ratio and pattern randomization. These techniques of intra‐panel interfaces will realize future tablets with high display resolution.

Published: July 2014

AbstractAn enhanced reduced voltage differential signaling (eRVDS) intra‐panel interface addressing both low‐power and low‐EMI requirements for tablet PC applications is presented. The proposed interface features a novel function called scrambled transition‐minimized coding (STMC) to perform both data pattern randomization and toggle reduction. Additionally, automatic skew calibration (ASC) is proposed to further reduce dynamic power and EMI radiation in the eRVDS interface. For verification, a WQXGA (2560times1600) TFT‐LCD system is implemented with the timing controller and source driver ICs that are fabricated using 65‐nm and 180‐nm CMOS processes, respectively. At the maximum operation speed of 1.8‐Gbps, the display module adopting the eRVDS interface demonstrated 24.3% power saving and 6.2‐dB suppression in EMI level.

AbstractWe have presented the brightness changes in positive and negative dielectric anisotropy liquid crystal (P‐LC and N‐LC) with different alignment materials for no eye‐strain at low frequencies. We propose a method for analyzing the brightness changes and find that flexoelectric effect (FEE) is a dominant factor to affect the eye‐strain in P‐LC, and the other crucial part is brightness holding ratio effect (BHRE). This work offers an easy approach to analyze the eye‐strain quantitatively, which indicates a way to solving the problem.

AbstractWe investigated the origins of the viewing angle problems caused in single‐domain AH‐IPS LC mode. To enhance the viewing angle property, we applied polystyrene which is well known for realizing zero pretilt angle. But polystyrene has poor alignment stability due to its low anchoring energy. In this paper, we improved alignment stability by employing UV‐curable reactive mesogen and enhanced the viewing angle property by realizing zero pretilt angle with rubbing process.

Authors: Farrell Joyce E. , Jiang Haomiao , Winawer Jonathan , Brainard David H. , Wandell Brian A. 
Published: July 2014

AbstractWe describe a new approach to the design of visible difference metrics that is based on calculating the information available at different points in the visual pathway and determining whether an ideal linear classifier can use this information to reliably predict the difference between two stimuli. This approach, referred to as the computational observer model, establishes a near upper bound on performance by assessing whether the information necessary to make discrimination is present in the visual system. We describe the implementation of a software framework that embodies the computational observer and illustrate how this framework can be used to address specific questions about display design.

Published: July 2014

AbstractContinuous improvements in inkjet printing of organic light emitting diode (OLED) displays have resulted in a number of recent demonstrations of uniform, mura‐free TV‐sized panels. These improvements combined with steady progress in solution OLED material performance, have allowed inkjet to become a realistic near term enabler of cost‐effective mass production of large size OLED TVs. However, for inkjet to make the transition from R&D to mass production, a number of equipment challenges must be overcome, including achieving low particle contamination, maintaining the optimal process environment while preserving serviceability, and providing consistent, uniform, mura‐free results with a wide process window. In this paper, the methodology (with respect to algorithms and process control) used in Kateeva's YIELDjet platform are described that lead to the uniform deposition of ink across an OLED display using inkjet printing, resulting in a highly uniform OLED emission with a wide process window.

Published: July 2014

AbstractHigh‐mobility single‐grain Si TFTs have been successfully fabricated on a polyimide‐coated substrate with solution process of Si. After doctor‐blade coating of cyclopentasilane (CPS), a‐Si:H was obtained at a temperature below 350°C. With dehydrogenation and crystallization by excimer laser, grains with a maximum diameter of 3 μm were obtained at predetermined positions. Single‐grain Si TFTs showed mobilities of 460cm2/Vs and 121cm2/Vs for electrons and holes, respectively. The devices were transferred onto a PEN foil and operated under a bending diameter as small as 6 mm. The results suggest the proposed technology to be attractive for various innovative applications, not only for driver‐integrated flexible displays, but also for ultra‐high‐frequency RF‐ID tag, highly‐sensitive bio‐medical sensors and eventually for integrated smart‐systems on a plastic.
