The SkyScout had a 12 channel GPS receiver and orientation sensors (whose accuracy was sensitive to proximity to metal objects, indicated by a horseshoe magnet icon on the display) that measured location and pointing angle. The LCD screen (known to scratch easily [citation needed]) displayed the name of the object (star, planet, deep sky object ...
With LCD screens, some manufacturers have opted to measure the contrast ratio and report the viewing angle as the angle where the contrast ratio exceeds 5:1 or 10:1, giving minimally acceptable viewing conditions. The viewing angle is measured from one direction to the opposite, giving a maximum of 180° for a flat, one-sided screen.
The viewing cone refers to the effective viewing directions of an LCD display, as seen from the eye. This collection of angles resembles a cone. The concept has been introduced as an international standard ISO 13406-2, which defines it as the range of viewing directions that can safely be used for the intended task without "reduced visual performance".
An LCD screen used as a notification panel for travellers. Each pixel of an LCD typically consists of a layer of molecules aligned between two transparent electrodes, often made of indium tin oxide (ITO) and two polarizing filters (parallel and perpendicular polarizers), the axes of transmission of which are (in most of the cases) perpendicular to each other.
An active-matrix liquid-crystal display (AMLCD) is a type of flat-panel display used in high-resolution TVs, computer monitors, notebook computers, tablet computers and smartphones with an LCD screen, due to low weight, very good image quality, wide color gamut and fast response time.
The articulating screen is known under different other names such as flip-out screen, flip screen, adjustable screen, articulated screen, or hinged screen. According to the way it moves, there are five main types: The display moves around one axis, so that it only tilts. It is called tilting screen or tiltable screen.
Clock with an early LCD prototype based on the twisted nematic field-effect. The twisted nematic effect (TN-effect) was a major technological breakthrough that made the manufacture of large, thin liquid crystal displays practical and cost competitive. Unlike earlier flat-panel displays, TN-cells did not require a current to flow for operation ...
Playdate uses a Sharp Memory LCD screen visually similar to e-paper displays. [11] Each pixel can remember its state (black/white) without needing to be refreshed, resulting in faster refreshing and lower power usage with a wide 170° viewing angle.
