Published: October 2010

AbstractAn LED streetlight with a new efficient cooling system was developed and demonstrated. The front side of an LED streetlight with Al heatsink and with a new heat exchange system were completely sealed by the transparent plastic case and the backside by the case made from Al plate. The temperature of the metal PCB within the lamp was 61 °C and 50 °C after 4 hours of operation at room temperature, respectively. The temperature of the metal PCB with the heat exchange system was much lower than the temperature with the LED streetlight with the conventional Al heatsink.

AbstractAn optimized energy efficient design of a Hybrid LED backlight is presented. This incorporates side‐emitting LEDs distributed equally in a two‐dimensional array across the backlight area and embedded in a multi‐layer light‐guide structure. Good energy efficiency is achieved by: 1. LEDs embedded in the light‐guide to remove air‐guide optical coupling loses, 2. Very short average optical path lengths (cm 's) to minimize optical loss in the light‐guide polymer, 3. Integrated high performance surface light extraction features to minimize surface scattering but achieve good extracted light beam profile. The combination of these features produces a high optical efficiency (>90%) and thin LED backlight. The full results from the design and manufacture of an optimized 40″ demonstrator will be presented.

Published: October 2010

AbstractAn evaluating procedure was introduced and demonstrated to reveal the impact of color appearance induced by ambient illumination for reflective‐type LCDs. The concepts of Color Rendering Index and Color Quality Scale were cooperated to account for the differences of color rendering between LED lightings with identical correlated color temperature but various spectra. The results showed that the colorimetric performance of reflective LCD was strongly dependent on various LED spectra and light level. And the proposed assessments, CRI and CQS, can effectively describe how well LED lighting renders the reflective‐type LCD.

AbstractIn this paper, we have fabricated TFTs with a‐IGZO. DC magnetron sputtering was employed for a‐IGZO deposition. The a‐IGZO TFTs were fabricated and evaluated using various deposition conditions with sputtering power and repeating the deposition of a‐IGZO. All TFTs were annealed after the deposition of etch stopper to maximize stability between a‐IGZO and etch stopper. Bias temperature stress characteristics were relevant to the initial property of a‐IGZO before annealing. Very stable TFTs were achieved optimizing the condition of a‐IGZO deposition and annealing after etch stopper. The Vth shift was 0.8V under positive bias temperature stress (Vgs=30V, 3600s, 60 °C). Also, the 17‐inch IPS AMLCD display panel with a‐IGZO TFTs was demonstrated.
