ELD stands for Electroluminescent Display
SED stands for Surface-conduction Electron-emitter Display
HMD stands for Head Mounted Display
A significant benefit of OLED displays over traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight to function. Thus they draw far less power and, when powered from a battery, can operate longer on the same charge. Because there is no need for a backlight, an OLED display can be much thinner than an LCD panel. Degradation of OLED materials has limited their use.
ELD works by exciting atoms by passing an electric current through them, causing them to emit photons. By varying the material being excited, the colour of the light emitted can be changed. The actual ELD is constructed using flat, opaque electrode strips running parallel to each other, covered by a layer of electroluminescent material, followed by another layer of electrodes, running perpendicular to the bottom layer. This top layer must be transparent in order to let light escape. At each intersection, the material lights, creating a pixel. ELDs are sometimes used as backlights in LCDs. They are also useful for creating soft ambient light, and for low-colour, high-contrast screens.
A surface-conduction electron-emitter display (SED) is a flat panel display technology that uses surface conduction electron emitters for every individual display pixel. The surface conduction emitter emits electrons that excite a phosphor coating on the display panel, the same basic concept found in traditional cathode ray tube (CRT) televisions. This means that SEDs use tiny cathode ray tubes behind every single pixel (instead of one tube for the whole display) and can combine the slim form factor of LCDs and plasma displays with the superior viewing angles, contrast, black levels, color definition and pixel response time of CRTs. Some also claim that SEDs consume less power than LCD displays.
A head-mounted display or Helmet mounted display, both abbreviated 'HMD', is a display device, worn on the head or as part of a helmet, that has a small display optic in front of one (monocular HMD) or each eye (binocular HMD). A typical HMD has either one or two small displays with lenses and semi-transparent mirrors embedded in a helmet, eye-glasses or visor. The display units are miniaturised and may include CRT, LCDs, Liquid Crystal on Silicon (LCos), or OLED. Some vendors employ multiple micro-displays to increase total resolution and field of view. HMDs differ in whether they can display just a computer generated image (CGI), show live images from the real world or a combination of both. Most HMDs display only a computer-generated image, sometimes referred to as a virtual image. Some HMDs allow superimposing a CGI upon a real-world view. This is sometimes referred to as augmented reality or mixed reality. Combining real-world view with CGI can be done by projecting the CGI through a partially reflective mirror and viewing the real world directly. This method is often called Optical See-Through. Combining real-world view with CGI can also be done electronically by accepting video from a camera and mixing it electronically with CGI. This method is often called Video See-Through. Major HMD applications include military, governmental (fire, police, etc.) and civilian/commercial (medicine, video gaming, sports, etc.). Military, police and firefighters use HMDs to display tactical information such as maps or thermal imaging data while viewing the real scene. HMDs are increasingly being integrated into the cockpits of modern helicopters and fighter aircraft. These are usually fully integrated with the pilot's flying helmet and may include protective visors, night vision devices and displays of other symbology. Engineers and scientists use HMDs to provide stereoscopic views of CAD schematics. These systems are also used in the maintenance of complex systems, as they can give a technician what is effectively ''x-ray vision'' by combining computer graphics such as system diagrams and imagery with the technician's natural vision. There are also applications in surgery, wherein a combination of radiographic data (CAT scans and MRI imaging) is combined with the surgeon's natural view of the operation. Low cost HMD devices are available for use with 3D games and entertainment applications. Such systems allow 'virtual' opponents to peek from real windows as a player moves about.
Other interesting recent technological developments AGS-TECH is closely monitoring are:
Laser illumination technology remained too costly to be used in commercially viable consumer products and too poor in performance to viably replace lamps except in some rare ultra-high-end projectors. However in recent years, companies demonstrated their laser illumination source for projection displays and a prototype rear-projection ''laser'' TV. The first commercial Laser TV, a 65'' model has been unveiled. First audiences who were shown reference clips from popular movies reported that they were blown away by a Laser TV's hitherto unseen color-display prowess. Some even described it as being too intense to the point of seeming artificial.
Other future display technologies may include carbon nanotubes (experimental), nanocrystal displays (experimental), using quantum dots to make vibrant, flexible screens.
As always, if you provide us details of your requirement and application, we can custom manufacture displays and touchscreens for you.
