Dual-touchscreen
A dual-touchscreen is a computer or phone display setup which uses two screens, either or both of which could be touch-capable, to display both elements of the computer's graphical user interface and virtualized implementations of common input devices, including virtual keyboards. Usually, in a dual-touchscreen computer or computing device, the most persistent GUI elements and functions are displayed on one, hand-accessible touchscreen (changing with the software application in use) alongside the virtual keyboard, while the other, more optically-centric display is used for those user interface elements which are either less or never accessed by user-generated behaviors. This approach is similar to that of the Nintendo DS handheld game console's construction, in which user-generated actions are initialized on the lower resistive touchscreen while the resulting graphical displays are executed in the upper screen. The same approach was adopted on its successor unit, the Nintendo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

AMOLED
AMOLED (active-matrix organic light-emitting diode; ) is a type of OLED display device technology. OLED describes a specific type of thin-film-display technology in which organic compounds form the electroluminescence, electroluminescent material, and active matrix refers to the technology behind the addressing of pixels. Since 2007, AMOLED technology has been used among mobile phones, media players, TVs and digital cameras, and the current progress over this technology is in lower power usage, lower cost, better resolution and specifically for larger screen (e.g. 8k screens). Design An AMOLED display consists of an active matrix of OLED pixels generating light (luminescence) upon electrical activation that have been deposited or integrated onto a thin-film transistor (TFT) array, which functions as a series of switches to control the current flowing to each individual pixel. Typically, this continuous current flow is controlled by at least two TFTs at each pixel (to trigger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

P-OLED
An organic light-emitting diode (OLED), also known as organic electroluminescent (organic EL) diode, is a type of light-emitting diode (LED) in which the emission (electromagnetic radiation), emissive electroluminescence, electroluminescent layer is an organic compound film that emits light in response to an electric current. This organic layer is situated between two electrodes; typically, at least one of these electrodes is transparent. OLEDs are used to create digital displays in devices such as television set, television screens, computer monitors, and portable systems such as smartphones and handheld game consoles. A major area of research is the development of white OLED devices for use in solid-state lighting applications. There are two main families of OLED: those based on small molecules and those employing polymers. Adding mobile ions to an OLED creates a light-emitting electrochemical cell (LEC) which has a slightly different mode of operation. An OLED display can be ...
