Flat-panel displays are thin panels of glass or plastic used for electronically displaying text, images, or video. Liquid crystal displays (LCD), OLED (organic light emitting diode) and microLED displays are not quite the same; since LCD uses a liquid crystal that reacts to an electric current blocking light or allowing it to pass through the panel, whereas OLED/microLED displays consist of ...
Matchbook cover, World War II, Uncle Sam. A "matchcover", or "matchbook cover", is a thin cardboard covering that folds over match sticks in a "book" or "pack" of matches. Covers have been used as a form of advertising since 1894, two years after they were patented, and since then, have attracted people who enjoy the hobby of collecting.
Smart glass in an opaque state. Smart glass,also known as switchable glass, dynamic glass, and smart-tinting glass, is a type of glassthat can change its optical properties, becoming opaque or tinted, in response to electrical or thermal signals. This can be used to prevent sunlight and heat from entering a building during hot days, improving ...
In many cases, flat-panel displays are combined with touch screen technology, which allows the user to interact with the display in a natural manner. For example, modern smartphone displays often use OLED panels, with capacitive touch screens. Flat-panel displays can be divided into two display device categories: volatile and static.
Flexible screens can open the doors to novel and alternative authentication schemes by emphasizing the interaction between the user and the touch screen. In “Bend Passwords: Using Gestures to Authenticate on Flexible Devices,” the authors introduce a new method called Bend Passwords where users perform bending gestures and deform the touch screen to unlock the phone.
Description and design. Window coverings comprise materials used to cover a window to manage sunlight, privacy, additional weatherproofing or for purely decorative purposes. Window coverings are typically used on the interior side of windows, but exterior solutions are also available. Window coverings may be used to manage overheating and glare ...
See-through display. An optical combiner for a see-through display. A see-through display or transparent display is an electronic display that allows the user to see what is shown on the screen while still being able to see through it. The main applications of this type of display are in head-up displays, augmented reality systems, digital ...
IPS panel. IPS ( in-plane switching) is a screen technology for liquid-crystal displays (LCDs). In IPS, a layer of liquid crystals is sandwiched between two glass surfaces. The liquid crystal molecules are aligned parallel to those surfaces in predetermined directions ( in-plane ). The molecules are reoriented by an applied electric field ...
