46.1: Invited Paper: A Novel Optical Switch and Display Based on Variable Aperture
Authors: Ren Hongwen , Xu Su 
Published: October 2012

AbstractWe report a novel optical switch and display using fringing field‐induced aperture change of a bracelet‐like liquid ring. To prove concept, we demonstrated a 4times4 color pixel array and a black‐and‐white single pixel for an optical switch. Without an electric field, the pixel has the largest clear aperture. The applied fringing field stretches the liquid surface, leading to a decreased aperture size. For a 230‐μm‐diameter pixel, the switchable aperture ratio is over 80% and the response time is ∼10 ms. This device has following advantages: polarization independence, fast response time, and easy fabrication.

56.4: Dual‐Gate IGZO TFT for Threshold‐ Voltage Compensation in AMOLED Pixel Circuit
Authors: Chou Lu‐Sheng , Chiu Hao‐Lin , Chen Bo‐Cheng , Tai Ya‐Hsiang 
Published: October 2012

AbstractIn addition to the gate electrode at the bottom, a dual‐gate InGaZnO4 (a‐IGZO) thin film transistor (TFT) has a secondary gate electrode on the top. The threshold voltage of the TFT using the bottom‐gate in its normal operation can be controlled by the top‐gate. Based on this phenomenon, a new concept of using the top‐gate to compensate threshold voltage variation is proposed. This new technique is demonstrated in two pixel circuits of active‐matrix organic light‐emitting diode and verified by the measurement results.

Published: October 2012

AbstractBridged grain (BG) technology was applied to fabricate MIC poly‐Si TFTs with AlOx gate dielectrics. The threshold voltage (Vth) and subthreshold swing (SS) of MIC TFTs are greatly improved. Meanwhile, the drawback of using high‐k dielectrics, such as large off‐state leakage current and early kink effect was effectively suppressed by using BG structure. Combination of BG and high‐k gate insulators makes the resulting device a promising candidate for system on panel applications.

P‐51: Low Temperature Crystallization of a‐InGaZnO4 Films
Authors: Hiroe Akihiko , Goto Tetsuya , Sugawa Shigetoshi , Ohmi Tadahiro 
Published: October 2012

AbstractWe have investigated the annealing behavior of a‐IGZO4 and found out that crystallization takes place at relatively low temperature of around 400°C when deposited by pure argon and then annealed in argon ambient. When deposited in 4%O2/Ar, on the other hand, only small network change is observed even after the annealing at 600°C in argon. These results show that oxygen vacancy, which is created during deposition and/or argon annealing, induces the lattice defects and helps create a crystalline phase of InGaZnO4.

P‐78: Electrophoretic Hybrid Particles Synthesis by Dispersion Polymerization in Organic Media: Towards Electrophoretic Display Applications
Authors: Charbonnier Antoine , Brochon Cyril , Cloutet Eric , Hadziioannou Georges 
Published: October 2012

AbstractThe effective sharing of information is a key parameter in our actual society. Electronic paper based on the controlled motion of electrophoretic particles appears thus promising since it combines the advantages of the usual paper (flexibility, reflective display) and the capacity to refresh information on the same support like the more common LCD or OLED technologies. Electrophoretic inks are composed of coloured charged particles which migrate under an electrical field between two electrodes. Depending of the position of the particles on the front plane, the colour on the screen can be tuned. The design of electrophoretic particles based on pigment or dyed polymer and their integration in electronic devices were successfully achieved during the last decade but are still limited to a two colour‐electrophoretic system. Up to date the majority of these particles were synthesized in aqueous media and the electrophoretic mobility was achieved by a ionic stabilizer or by a polyelectrolyte surfactant. Moreover the final electrophoretic particles incorporated in the electronic devices have to be dispersed in an organic media (paraffin oil) in order to achieve the desired stability of the display and thus leads to a large variety of problems during the phase exchange process.In this work our goals were to rationalize and improve the ink synthesis as well as to design electrophoretic inks with the full colour panel in order to realize the next generation of electrophoretic displays. We performed the particle synthesis by using an organic dispersion technique in aliphatic hydrocarbon solvents leading to chargeable electrophoretic particles with a good size control over a large range (from 75nm to 20μm) and a good stability. In order to obtain the full color panel, the encapsulation of several inorganic pigments was achieved by using the same technique and the electrophoretic behaviour of the resulting inks was characterized in a cell specially designed for electrophoretic measurements in organic media.

AbstractWe present advanced patterned vertical aligned nematic liquid crystal (APVA) mode characterized by multi‐electrodes with fixed voltages which play important role to generate horizontal electric field that prevents LC disclination in vicinity of the middle region of electrodes exhibiting patterned vertically aligned nematic liquid crystal mode (PVA mode). The proposed APVA mode is focused on improving dramatically transmittance with excellent image quality. The APVA mode improves transmittance by 20%, compared with the conventional VA modes. So the proposed APVA mode can improve response speed and transmittance remarkably. Consequently, it is useful to upgrade the LCD display quality.

Published: October 2012

AbstractA new architecture to improve the SNR of the readout circuit for capacitive TSPs is introduced. The architecture shows better performance in spite of requiring less power consumption and using an integration capacitor that is roughly half in size compared with a previous work. It averages noises by repeated integration and substantially mitigates the effect of display noise through a differential sensing technique. Furthermore, it does not require additional calibration circuitry to correct the settling error by different delay paths because two adjacent lines in differential sensing have almost the same R‐C time constant. The circuit is designed in a 0.35 μm CMOS technology.
