A backlight is a form of illumination used in liquid crystal displays (LCDs). One type of backlight is made by LEDs, which can be either white or RGB (red green blue). White LEDs are used most often in notebooks and desktop screens, and in virtually all mobile LCD screens. RGB LEDs for backlighting are found in high-end color proofing displays such as HP DreamColor LP2480zx monitor or selected HP EliteBook notebooks, as well as newer consumer grade displays such as Dell's Studio series laptops which have an optional RGB LED display.

Le rapport d'aspect est le rapport entre la largeur d'une image et sa hauteur. Le rapport d'aspect natif est celui pour lequel le projecteur/écran est particulièrement conçu. Les images affichées dans leur format d'origine utiliseront toute la résolution de l'écran et atteindront une luminosité maximale. Les images affichées dans un format autre que le format d'origine auront toujours une résolution et une luminosité moindres que les images affichées dans le format d'origine.

La luminosité est la qualité de la quantité de lumière rayonnante émise par l'écran. La luminosité est mesurée en candelas par mètre carré, communément appelés "nits".

La différence d'intensité lumineuse entre le blanc le plus clair et le noir le plus foncé.

Bluetooth is a low-power radio technology developed to replace the cables and wires currently used to link or connect electronic devices such as personal computers, printers, and a wide variety of handheld devices including mobile phones. Because it uses radio-wave connectivity, a Bluetooth-enabled device has a constant, established connection to whatever browser it uses. This saves the user the trouble of logging on to check for emails or news updates, for example.

The type of bluetooth technology in the product e.g. Bluetooth Smart (v4.0).

Type of operating system on a device e.g. IOS on Apple devices, Android for mobile devices.

Software distributed with another product such as a piece of computer hardware or other electronic device, or a group of software packages which are sold together. A software suite is an example of bundled software, as is software which is pre-installed on a new computer.

The type of battery in the device, e.g. nickel–cadmium (NiCd).

A measure of the charge stored by the battery. Determined by the mass of active material contained in the battery.

Holes on the edge of devices through which a cable lock can be passed, so the device can be locked to a desk etc.

A scanner used to identify a person's fingerprint for security purposes. After a sample is taken, access to a computer or other system is granted if the fingerprint matches the stored sample. A PIN may also be used with the fingerprint sample.
