Abstract— By using 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 (a‐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. A high‐performance 14‐in. AMOLED display was fabricated by 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. 相似文献

High pixel density displays are demanded for active matrix organic light‐emitting diode displays (AMOLED) in applications such as virtual reality headsets, micro‐displays, and high‐end smartphones. Parasitic emission from non‐addressed neighboring pixels (crosstalk) is a common problem in such high pixel density AMOLED, and this crosstalk becomes more severe as the pixel density and fill ratio of the display increases. One of the causes of crosstalk is parasitic currents that travel through common organic semiconductor layers. In this paper, we model and quantify the pixel crosstalk using a 2 + 1D finite element model that is based on the conductivity of the common layer and the luminance–current–voltage curves of the subpixels as measured input parameters. We assess the effect of crosstalk on the pixel current, observed color, and luminance. The 2 + 1D model limits the number of degrees of freedom so that calculations on a standard personal computer are feasible. 相似文献

Abstract— A high‐transmittance transflective device based on a hybrid structure consisting of a transparent organic light‐emitting diode (OLED) stacked on top of a reflective liquid‐crystal device (RLCD) was conceptually demonstrated. By placing the transparent OLED on top of a vertically aligned LCD operated under normally black mode, a transmittance as high as 75.7% was obtained due to the asymmetric emission characteristics of a transparent OLED. To further improve the performance in the transmissive mode, a polarizer‐free LCD was used, which yielded an ultra‐high transmittance (82.2% overall). 相似文献

A flexible vertically stacked flexible polychromatic color‐tunable OLED has been developed by means of low resistive intermediate electrode technology. The polychromatic OLED has a capability to show 16 million colors with 105% National Television Committee Standard (NTSC) color reproduction. The device can produce arbitrary shape with arbitrary colors, suitable for artistic expressions, just as many as those used in information displays. Independently controlled red, green, and blue light‐emitting layers are stacked vertically. With conventional indium tin oxide technology, because of the temperature restriction, it was quite difficult to achieve low resistance on plastic substrate. The reported numbers were all more than 80 Ω/□. According to the surface mobility control using Fick's law analysis, low sheet resistance 7.34 Ω/□ on plastic film was developed. At first, flexible 7.17 cm2 transparent OLED was fabricated for the performance confirmation of transparent electrode. And then polychromatic color‐tunable OLED with the same size were successfully fabricated on plastic. With optical length optimization for each color stack of polychromatic OLED, more than 100% color reproduction in National Television Committee Standard was achieved by stack design. The polychromatic device can be used for colored illumination, as well as for organic‐light‐emitting display pixels for three times emission than conventional pixel design. The device is fabricated on plastic substrate so that the polychromatic organic‐light‐emitting‐diode device is manufacturable with roll‐to‐roll production line. 相似文献

We fabricated new 2.78‐in 1058‐ppi organic light‐emitting diode (OLED) displays. The displays used OLED devices with a tandem structure and a single structure and a field effect transistor (FET) using c‐axis aligned crystalline In–Ga–Zn–O (CAAC‐IGZO) for an active layer and employing the 1.5‐µm rule over a glass substrate. Even in the displays with such high resolution exceeding 1000 ppi, crosstalk that was observed in the lower luminance region was suppressed. The displays achieved high color reproducibility and reduced viewing angle dependence. 相似文献

Abstract— A highly efficient deep‐blue organic light‐emitting device (OLED) incorporating a novel composite hole‐transport layer (c‐HTL) and an emitter based on the new non‐symmetrical mono(styryl)amine fluorescent dopant in the stable host MADN, which achieved a luminance efficiency of 5.4 cd/A with a Commission Internationale d'Eclairage (CIEx,y) of (0.14, 0.13) and an external quantum efficiency of 5.1% at 20 mA/cm2 and 6.8 V, is reported. The increased device efficiency is attributed to an improved balance between hole and electron currents in the recombination zone. 相似文献

In this work, novel blue‐fluorescent dopants with a heteroaromatic ring skeleton instead of the conventional pyrene skeleton were investigated. Bottom‐emission organic light‐emitting diodes (OLEDs) fabricated using the novel blue‐fluorescent dopants in light‐emitting layers achieved better deep‐blue chromaticity than OLEDs based on a conventional pyrene‐based dopant, while maintaining both high external quantum efficiency (EQE) and comparable reliability. The attainment of deep‐blue chromaticity without losing high EQE was ascribed to the improvement of the efficiency of energy transfer from the host to the dopant. Furthermore, it was estimated that using this novel dopant in a top‐emission OLED panel that satisfies BT.2020 chromaticity enables the power consumption of the whole panel to be 24% lower than that of the panel with a conventional dopant. 相似文献

Abstract— A transfer‐printing method for the patterning of thin polymer layers is described. A hard stamp with a raised feature is brought into contact with a spin‐coated organic film under elevated pressure and temperature to break the films. The patterned film is then transfer printed onto the devices. This method is used to print red/green/blue subpixel arrays with a pattern size as small as 12 μm at a resolution of 530 ppi to demonstrate its ability for full‐color organic light‐emitting‐display fabrication. Devices with printed organic layers have similar performance to spin‐coated controls under optimized printing temperature and pressure settings. The critical physical parameters include a soft intermediate plate for the sharp breaking of edge patterns, control of surface energies, and printing at moderate temperature and pressure to achieve intimate contact between the printed layer and the underlying substrate. 相似文献

Abstract — We achieved operationally stable white OLEDs with a single solution processed EML fabricated using a self‐layered technique. An LT70 of 10 khr at an initial luminance of 1000 cd/m2 was obtained by suppressing the exciplex formation between the EML and ETL, preventing Li diffusion into the EMLs, and using red dopants with shallow LUMO levels and stable host materials. 相似文献

In this paper, the information package (IP) used within the Victorian Electronic Records Strategy (VERS) is described. The
VERS IP was designed in 1999 to support the long-term preservation of digital information and has been implemented in government
agencies and it is the basis of the Public Record Office Victoria's digital archive. Its key feature is the use of a self-documenting
encapsulation. The encapsulation binds the content information to be preserved and its metadata into a single object that
can survive independently of an archival system. The self-documentation ensures that the content can be manually extracted
from the encapsulation using only the simplest tools. The VERS IP is compared with the IP defined in the Open Archival Information
System (OAIS) and the Metadata Encoding and Transmission Standard (METS). 相似文献
