Tech Glossary
A curated, technical glossary covering display, touch, and deployment terminology used across Tech Global solutions.
Showing 54 terms.
Touch at each position on the glass generates a unique sound. Four tiny transducers attached to the edges of the touch screen glass pick up the sound, which is digitized and compared to prerecorded sounds for each position. The system updates cursor position instantly and is effective on larger displays, with tolerance for scratches and dust. A motionless finger cannot be detected. (See Single-Touch)
(active-matrix organic light-emitting diode) is a display technology for use in mobile devices and televisions. OLED refers to thin-film electroluminescent materials, while active matrix refers to the pixel addressing method.
The proportional relationship between image width and height.
Illumination used in LCDs, which do not emit light themselves. Backlights illuminate LCDs from the side or back and improve readability in low-light conditions.
OEM monitor manufacturer.
A touch panel made from an insulator like glass with a transparent conductive coating. A finger changes the electrostatic field by distortion, which is measured as a capacitance change. The location is processed by a controller. Requires a conductive body or special glove/stylus in many use cases.
A cold cathode used in gas discharge lamps such as nixie tubes and some vacuum tube types; not electrically heated by the circuit.
Delivery of computing resources, software, and information as a metered service over a network, typically the Internet.
17"–30" small format monitor with a built-in stand.
17"–30" small format electronic display used for menus, information, advertising, television programming, and similar messages.
Digital public-display systems that protect information and are designed for public environments and outdoor/field use.
Sensors detect piezoelectric signals generated in glass by a touch. Algorithms locate the point of contact. It works well with dust and scratches and does not need extra touch-layer elements. Works with fingers or styluses but cannot detect a stationary finger.
Common display metrics include luminance (cd/m²), aspect ratio, viewable image size, resolution, dot pitch, refresh rate, response time, contrast ratio, power consumption, delta-E color accuracy, and viewing angle.
Protective filters for LCD screens that help resist dust, dirt, and impacts from light accidental contact; useful accessories for prolonging display life.
Touch technology that supports two simultaneous inputs and may support gesture control.
A durable surface capacitive stack with high optical quality, anti-bacterial characteristics, 9H hardness and vandal-resistant design. Supports glove use and advanced gesture use in some variants.
A thin LED back-lighting architecture where LEDs are placed around the edge of the panel and diffuser layers spread light uniformly.
Protective, easy-to-clean solutions used in school environments to reduce visible residue and maintain clean touchscreen/monitor surfaces.
A complete computer integrated on a single board for dedicated functional use, often built around controllers, microcontrollers, or DSP processors.
A motherboard interface on a motherboard or backplane that accepts cards to add functionality through an expansion bus.
Recognized finger motions on touch surfaces (for example, pinch, rotate, swipe, scroll) that trigger programmable actions in software.
Display technology in healthcare environments where protective surfaces must tolerate frequent sanitizing chemicals.
Sunlight-readable monitor often used for kiosk or outdoor advertising in high-ambient-light conditions.
IR touch uses LED/photo-detector arrays on panel edges to detect disruptions in light paths. It supports stylus, pen, and gloved input in many cases, with higher point counts for multi-touch.
Relating to continuous two-way information exchange between user and a system such as a computer, kiosk, or display.
An interactive terminal with public-facing interfaces, typically for guided self-service.
A 32"+ monitor.
A 32"+ display used to present programming, menus, information, advertising, and message streams in commercial spaces.
Liquid-crystal display: a low-power flat-panel technology that uses electrically charged liquid crystals between layers to control light transmission.
Semiconductor diode that emits light when conducting current; used widely in electronics and digital displays.
An LCD display that uses LED backlight for thinner panels, lower power consumption, and improved heat management compared with CCFL systems.
LG Display Solutions is referenced as a commercial display OEM partner.
A visual display unit for computers made of a display panel plus enclosure, circuitry, and related controls.
Surface that detects multiple touch points simultaneously, enabling advanced gestures such as pinch and zoom.
NEC Display Solutions is referenced as a commercial display OEM partner (alongside Sharp).
Technology using cameras around display corners/edges to detect finger/hand occlusion by shadow and triangulate touch points and object size.
Open Pluggable Specification (OPS) creates interoperable standards for digital signage players and peripherals, helping modular deployment and easier upgrades.
A client virtualization model that separates desktop rendering from a remote compute source via server-side infrastructure.
Point-of-sale; point-of-sales systems used in retail workflows.
An accessory that narrows viewing angle to prevent side viewing, useful in healthcare, financial, and education environments.
Projected capacitive touch forms an electrode grid and can operate under protectors or glass. Supports multiple points and may support stylus depending on implementation.
A touch screen using conductive layers that register contact when pressed together. It is inexpensive and robust around contaminants but lower-cost and lower-resolution by nature.
A complete computer built on one circuit board with processor, memory, I/O, and support logic in one compact module.
Touch technology that resolves one input at a time and supports simple gestures such as swipe and scroll.
Monitor diagonal screen dimension.
A traditional monitor aspect format of 4:3 or 5:4.
A conductive surface layer forms a uniform field, and a finger creates a measurable capacitance change at one point. Often reliable for industrial control and kiosk use.
A visual display interface where touching the display surface sends user commands without needing physical keyboards.
A high-clarity, lightweight display protector material (acrylic/polycarbonate) with very low glare and strong scratch resistance.
A privacy solution integrated with armor and touch stack technologies to reduce shoulder-surfing and side-angle leakage.
A company that manufactures interactive hardware and software for medical, industrial, retail, education, and other verticals.
A virtualization platform allowing multiple VMs to run with a host OS; supports desktop and infrastructure separation for managed environments.
All Tech Global products carry warranty; coverage details are assigned per product and sold through sales support.
Display geometry wider than standard formats (such as 16:9 or similar), commonly used for modern video and digital signage experiences.
