Abstract:

Optical metasurfaces are starting to find their way into integrated devices, where they can enhance and control the emission, modulation, dynamic shaping, and detection of light waves. In this study, we show that the architecture of organic light-emitting diode (OLED) displays can be completely reenvisioned through the introduction of nanopatterned metasurface mirrors. In the resulting meta-OLED displays, different metasurface patterns define red, green, and blue pixels and ensure optimized extraction of these colors from organic, white light emitters. This new architecture facilitates the cre

Abstract:

A 1.03‐inch 2560x2560 low power OLEDoS backplane with a proposed in‐pixel up‐scaling technique is designed and implemented. Due to the proposed technique based on interpolated pixel scheme, the pixel density of the backplane realizes 3514 PPI (Pixels per Inch) with lower power consumption. The backplane has 1280x1280 input video resolution and output video resolution is upscaled to 2560x2560 without additional up‐scaler. A measured power consumption per 1 mega pixel without OLED frontplane is 16.3mW which is less than our previous 0.7‐inch 1920x1080 OLEDoS backplane with the same semiconductor

Wafer-scale blue micro-light-emitting diode (micro-LED) arrays were fabricated with a pixel size of 12 μm, a pixel pitch of 15 μm, and a pixel density of 1692 pixels per inch, achieved by optimizing the properties of e-beam-deposited and sputter-deposited indium tin oxide (ITO). Although the sputter-deposited ITO (S-ITO) films exhibited a densely packed morphology and lower resistivity compared to the e-beam-deposited ITO (E-ITO) films, the forward voltage (VF) values of a micro-LED with the S-ITO films were higher than those with the E-ITO films.

According to the simulation results and a layout example, the proposed pixel circuit is expected to be applied in high pixels per inch (PPI) car displays in the future.

The QD‐LEDs with the nonohybrids showed a higher current efficiency over 4‐fold than that with a QD‐only active layer. EHD jet‐printing was independently performed up to 5µm pixel pitch on a substrate, resulting in a resolution of ca. 5,080 pixels per inch.

Abstract:

LaserJets, like many other printers, print in lines per inch (Ipi). The lines represent in digital image printing lines of pixels. If the pixels are printed squarely than each square area (of a width equal to that of the actual line width) must be printed with a desired amount of ink variations in order to generate the gray levels (see John Russ’ book for a nice illustration on how this is done in a LaserJet). LaserJets and Inkjets use dots as the smallest printed entity.

In NC-BPDVC, we convert the grayscale secret image into a multitone image by multilevel halftoning.

Abstract Perovskite quantum dots (PeQDs) are considered potential display materials due to their high color purity, high photoluminescence quantum yield (PLQY), low cost and easy film casting. In this work, a novel electroluminescence (EL) device consisting of the interface layer of long alkyl-based oleylammonium bromide (OAmBr), which passivates the surface defects of PeQDs and adjusts the carrier transport properties, was designed. The PLQY of the OAmBr/PeQD bilayer was significantly improved. A high-performance EL device with the structure of indium tin oxide/poly(3,4-ethylenedioxythiophene

Abstract:

The significance of backplane devices for ultra-high-resolution (UHR) display has increased with the recent development of augmented reality (AR) and virtual reality (VR) devices. Since the human visual resolution can distinguish up to 60 pixels per degree (PPD), the AR/VR device panel needs at least 3000 pixels per inch (PPI) to exceed the human retina resolution limit for clear display without screen effect. As a results, the unit pixel pitch of thin film transistor (TFT) for UHR display should be not only smaller than a few micrometers (~3 μm), TFT channel length should also be sub-micromet

Abstract:

This paper proposes an image processing approach to identify Gram-negative bacteria. Gram-negative bacteria are one of the bacteria that cause lung lobe damage-bacterial samples obtained through smears of the patient's sputum. The first step bacterium should pass the pathogen test process. After that, it bred using Mc Conkey's media. The problem faced is that the process of identifying bacterial objects is still done manually under a fluorescence microscope. The contributions offered from this research are focused on observing bacterial morphology for the operation of selecting shape f

Objectives: Since the easiest way to identify pills and obtain information about them is to distinguish them visually, many studies on image processing technology exist.

In the AMOLED display, many factors affect the user's visual perception, such as color ratio, refresh rate and drive ability of array circuit, pixel density and so on. In the past, the primary idea to improve the precision and smoothness of the display quality is to increase the pixel per inch (PPI) and optimize the sub pixel rendering (SPR) algorithm between pixel units. At present, the PPI has gradually stabilized at 400+ grade for mobile phone display, and the IC driver algorithm corresponding to the pixel arrangement of each panel factory has also stabilized gradually, therefore, more effo

The holographic image quality within phase‐only LCOS not only can be improved by using higher phase accuracy and compensation technologies, but also can realize the real 3D imaging into near‐eye displays to avoid the VAC phenomena.

However, reduced transistor count increases Vth variation, while smaller storage capacitors with higher parasitic capacitance degrade image quality.
