Published: August 2007

AbstractWe describe a new single layer anti‐reflective film for optical display applications. The performance advantages of this new AR film are described including low reflectivity, neutral color, abrasion resistance to steel wool and low haze. The film's properties are discussed, along with reflectivity and abrasion resistance up to 400gr/cm2. In order to quantify the abrasion resistance, we've developed a procedure to image the scratches of abraded samples and quantify the scratches in terms of the percent of image that is abraded. This new technique that will be described is reproducible and correlates well with visual scratch observations.

Published: August 2007

AbstractUsing current technology, it is possible to design and fabricate performance‐competitive TV‐Sized AMOLED displays. In this paper the system design considerations are described that lead to the selection of the device architecture (including a stacked white OLED‐emitting unit), the backplane technology (an amorphous Si backplane with compensation for TFT degradation), and module design (for long life and low cost). The resulting AMOLED displays will meet performance and lifetime requirements, and will be manufacturing cost‐competitive for TV applications. We fabricated a high‐performance 14″ AMOLED display using an in‐line OLED deposition machine to demonstrate some of these approaches. The chosen OLED technologies are scalable to larger glass substrate sizes compatible with existing a‐Si backplane fabs.

As a first step toward the mass production, we set up Gen 4 LITI pilot system.

Published: August 2007

AbstractThe applicability of an ink‐jet printing method to microdeposition of high‐viscosity resin and phosphor dispersion for light‐emitting‐diode (LED) packaging was examined for the first time. An ultrasonic ink‐jet printing method was used, in which ink droplets are ejected by focused ultrasonic beam from nozzle‐less printhead. for fabricating white LEDs, high‐viscosity phosphor‐dispersed resin was deposited to form an encapsulant dome, and hydrophobic surface treatment of the lead frame substrate enabled fabrication of a small encapsulant dome to improve color uniformity. A silicone microlens was deposited on an encapsulant dome using the ink‐jet method for light directivity control. The results show the ultrasonic ink‐jet printing is an applicable technique to optimize and modify on demand optical characteristics of the LED devices.

Published: August 2007

AbstractA single‐wall carbon nanotube (SWNT) transparent conductive film (TCF) was fabricated using a simple inkjet printing method. The TCF could be selectively patterned by controlling the dot size to diameters as small as 34μm. In this repeatable and scalable process, we achieved 71% film transmittance and a resistance of 900 ohm/sq sheet with an excellent uniformity, about ± 5% deviation overall. Inkjet printing of SWNT is substrate friendly and the TCF is printed on a flexible substrate. This method of fabrication using direct printing permits mass production of TCF in a large area process, reducing processing steps and yielding low‐cost TCF fabrications on a designated area using simple printing.

Published: August 2007

AbstractRecent TFT‐LCD panels continue to increase their sizes. When TFT‐LCD panels become large, the image data writing into liquid crystal cells becomes a serious issue. This issue is caused by a large RC‐delay due to the loads for TFT‐LCD panel's data‐lines. In this paper, we propose a Pre‐Empasis Driving which can reduce writing times into liquid crystal cells. Using the proposed driving, writing into pixels for 37 inch panels can be completed within about 1 us.

Published: August 2007

AbstractTwisted Nematic (TN) liquid crystal display is optimized for transflective liquid crystal displays. This new configuration does not need to separate the pixel into two sub‐pixels of transmissive and reflective mode. Each pixel is partially transmissive and reflective with the help of a semi transparent mirror. The electro‐optical characteristics in the transmissive mode and reflective mode match each other, which indicates that the transmissive and reflective function could be controlled using the same voltage in a transflective LCD. This TN LCD configuration has a good contrast, viewing angle, response time and color coordination. Also it is very easy to fabricate and suitable for high quality transflective TFT‐LCDs.

Dual emission layer white OLED devices were fabricated using high Tg materials with typical efficiencies ∼ 10 cd/A and CIE x and y coordinates of 0.32 and 0.34 respectively. Stable color coordinates over a wide range of video grey levels were obtained from white using color filters. Room temperature operating luminance half‐life at 20 mA/cm2 exceeds 6,000 hrs (>25,000 hrs in video mode). The optical characteristics of the devices were simulated using a full vector field calculation.

AbstractIn this paper, we describe our development of Frame Rate Conversion (FRC) technology that provides picture quality improvement for LCD by doubling its frame rate. Based on an analysis of motion speed of real broadcasting video, we point out that the “character telop” is a special type of input signal that is considered to be able to obtain a significant picture quality improvement by using double‐frame rate LCD‐TV. Then, an FRC technology that has a feature of improving a picture quality of “character telop” in particular, as well as a LSI implementing FRC is introduced. We also verified that the FRC was effective by actually measuring the effect using TV sets equipped with the FRC‐LSI.

66.1: Distinguished Student Paper: Deriving LED Driving Signal for Area‐Adaptive LED Backlight in High Dynamic Range LCD Displays
Authors: Li Feng , Feng Xiaofan , Sezan Ibrahim , Daly Scott 
Published: August 2007

AbstractLED backlight technique dramatically enhances the dynamic range of an LCD display and hence extends its ability to present images with high reality. This is achieved by modulating LEDs individually, thus providing an area‐adaptive backlight for the display. However, crosstalk of LEDs is not only a blessing for supplying high brightness but is also a curse for causing potential artifacts, making the derivation of LED driving signal a challenging task. This paper formulates the problem in two mathematical models: an iterative de‐convolution approach and a linear optimization approach. Algorithms for solving these two models are provided. An image database composed of 161 high dynamic range images is built to evaluate the performances of these two approaches.

Published: August 2007

AbstractA novel emi‐flective display that integrates a reflective liquid crystal display (R‐LCD) and an organic light emitting diode (OLED) display was demonstrated. Under the light ambience of 30 nits, the OLED achieved a gain factor of 8 in contrast ratio (CR) compared with the conventional non‐integrated OLED; besides, the OLED was fully operational and the system's CR of 5000:1 at the viewing cone of 50° could be achieved. Moreover, the R‐LCD retained a CR of 10:1 at the viewing cone of 55° in the bright ambience. To enhance the image quality of both R‐LCD and OLED, we laid a nano‐particle film (NPF) in the intermediate section of the hybrid device. The NPF was demonstrated to enhance the light extraction in transmission mode of the integrated device to 103% and the haze function of the reflection mode to a factor of 15 compared with the freestanding mirror.
