OLED in the context of "Touch screen"

A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device. Touchscreens are commonly found in smartphones, tablets, laptops, and other electronic devices. The display is often an LCD, AMOLED or OLED display.

A user can give input or control the information processing system through simple or multi-touch gestures by touching the screen with a special stylus or one or more fingers. Some touchscreens use ordinary or specially coated gloves to work, while others may only work using a special stylus or pen. The user can use the touchscreen to react to what is displayed and, if the software allows, to control how it is displayed; for example, zooming to increase the text size.

Primary colors are colorants or coloured lights that can be mixed in varying amounts to produce a gamut of colors. This is the essential method used to create the perception of a broad range of colors in, e.g., electronic displays, color printing, and paintings. Perceptions associated with a given combination of primary colors can be predicted by an appropriate mixing model (e.g., additive, subtractive) that uses the physics of how light interacts with physical media, and ultimately the retina to be able to accurately display the intended colors.

The most common colour mixing models are the additive primary colors (red, green, blue) and the subtractive primary colors (cyan, magenta, yellow). Red, yellow, and blue are also commonly taught as primary colors (usually in the context of subtractive color mixing as opposed to additive color mixing), despite some criticism due to its lack of scientific basis.

AMOLED (active-matrix organic light-emitting diode; /ˈæmoʊˌlɛd/) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescent material, and active matrix refers to the technology behind the addressing of pixels.

Since 2007, AMOLED displays have been used in mobile phones, media players, TVs, and digital cameras. The current progress for this technology is towards lower power usage, lower cost, and higher screen resolutions (e.g., 8K).

The Nintendo Switch is a video game console developed by Nintendo and released worldwide in most regions on March 3, 2017. Released in the middle of the eighth generation of home consoles, the Switch succeeded the Wii U and competed with Sony's PlayStation 4 and Microsoft's Xbox One; it also competes with the ninth generation consoles, the PlayStation 5 and Xbox Series X/S.

The Switch is a tablet that can either be docked for home console use or used as a portable device, making it a hybrid console. Its wireless Joy-Con controllers function as two halves of a standard controller and alternatively as individual controllers, featuring buttons, directional analog sticks for user input, motion sensing, and tactile feedback. A pair can attach to the sides of the console for handheld-style play, attach to a grip accessory to provide the form of a separated gamepad, or be used unattached. The Switch's system software supports online gaming through internet connectivity, as well as local wireless ad hoc connectivity with other consoles. Switch games and software are available on both physical flash-based ROM cartridges and digital distribution via Nintendo eShop; the system has no region lockout. Two hardware revisions were released: the handheld-only Switch Lite, released on September 20, 2019; and a higher-end version featuring an OLED screen, released on October 8, 2021.

A dot-matrix display is a low-cost electronic digital display device that displays information on machines such as clocks, watches, calculators, and many other devices requiring a simple alphanumeric (and/or graphic) display device of limited resolution.

The display consists of a dot matrix of lights or mechanical indicators arranged in a rectangular configuration (other shapes are also possible, although not common) such that by switching on or off selected dots, text or graphics can be displayed. These displays are normally created using LCD, OLED, or LED technology. Some later VF Displays also use a dot-matrix instead of a Seven-segment display. A dot-matrix display controller converts instructions from a processor into signals that control the individual dots in the matrix so that the required display is produced.

Moisture vapor transmission rate (MVTR), also water vapor transmission rate (WVTR), is a measure of the passage of water vapor through a substance. It is a measure of the permeability for vapor barriers.

There are many industries where moisture control is critical. Moisture sensitive foods and pharmaceuticals are put in packaging with controlled MVTR to achieve the required quality, safety, and shelf life. In clothing, MVTR as a measure of breathability has contributed to greater comfort for wearers of clothing for outdoor activity. The building materials industry also manages the moisture barrier properties in architectural components to ensure the correct moisture levels in the internal spaces of buildings. Optoelectronic devices based on organic material, generally named OLEDs, need an encapsulation with low values of WVTR to guarantee the same performances over the lifetime of the device.
