“…In addition, the more pixels for the EL display are, the more cost the driver will be. That's why the colorful EL displays are not small and cheap [25][26][27]. Except the colorful display, the monochrome EL materials are cheaper and widely used as a visual indication for many devices such as watch backlight or exit indicators.…”

Visualizing mechanical strain/stress changes is an emerging area in structural health monitoring. Several ways are available for strain change visualization through the color/brightness change of the materials subjected to the mechanical stresses, for example, using mechanoluminescence (ML) materials and mechanoresponsive polymers (MRP). However, these approaches were not effectively applicable for civil engineering system yet, due to insufficient sensitivity to lowlevel strain of typical civil structures and limitation in measuring both static and dynamic strain. In this study, design and validation for high-sensitivity strain visualization using electroluminescence technologies are presented. A highsensitivity Wheatstone bridge, of which bridge balance is precisely controllable circuits, is used with a gain-adjustable amplifier. The monochrome electroluminescence (EL) technology is employed to convert both static and dynamic strain change into brightness/color change of the EL materials, through either brightness change mode (BCM) or color alternation mode (CAM). A prototype has been made and calibrated in lab, the linearity between strain and brightness change has been investigated.

“…Another technology which has been used to fabricate microdisplays is thin-film electroluminescence [5] (TFEL), wherein a thin film of ZnS sandwiched between two insulating films emits light under the influence of a high electric field of alternating polarity. In this case, the emitting structure is deposited onto a silicon chip containing the active-matrix circuitry.…”

“…for video-rate high-information-content flat-panel displays (those of formats greater than QVGA color). While dualor quad-scan techniques 5 have been used for directview LCDs, essentially for cost reasons, the resulting performance has always been compromised, frequently exhibiting crosstalk and response-time artifacts. A scanned display uses only one line or column of information and an electromechanical system that moves this line perpendicularly to create a virtual image plane.…”

Microdisplays, some of which exploit the dense electronic circuitry in a silicon chip, are enabling a new wave of ultraportable information products, including headsets for viewing movies and cell phones with fullscreen Internet access. This paper reports the approach to microdisplay development at eMagin Corporation. The requirements for microdisplays are reviewed, and the case is made that organic light-emitting diodes (OLEDs) are the best candidate transducer technology for meeting these requirements. A 1280 ؋ 1024 (SXGA) monochrome OLED microdisplay is described as an example.

“…Display devices such as color plasma display panels (PDPs) [1], digital micromirror devices (DMDs) [2], ferroelectric LCDs [3], and ELs [4] reconstruct gray scales and colors by combining frame-sequential sub-sets of pictures. For PDPs, one TV field of 16.7 ms is divided into typically 8 sub-fields, whose light-emission durations are arranged according to the 1-2-4-8-... binary sequence as shown in Fig.…”

Many display devices including color PDPs, DMDs, ferroelectric LCDs, and ELs express gray levels by accumulating pictures of multiple sub-frames with the aid of retinal after-image effect. Additionally, some of these devices use frame-sequential color-multiplexed backlights. When the observer's eye sweeps across the screen, unexpected visual artifacts, e.g. false contours and color breakup may be produced.These artifacts will be quantified, and methods of reducing them will be introduced.
