Est-ce que le camescope possède un écran LCD ou OLED?

Le LCD est un écran à cristaux liquides. Ces écrans sont très plats et petits.
Ils vous permettent de visualiser en direct le résultat de votre enregistrement, comme sur une petite télévision. Il peut être utilisé en remplacement du viseur traditionnel. Par ailleurs, ces écrans sont souvent rotatifs et/ou inclinables, ce qui donne une plus grande liberté de mouvement lors de la prise de vues.

LE OLED est une technologie d'affichage lumineux apparue vers 1995 et mise au point par Kodak.
Avantages: faible consommation électrique, meilleur rendu des couleurs, meilleur contraste et angle de confort de vision plus étendu, minceur et souplesse de l'écran.

(Universal Serial Bus) A widely used hardware interface for attaching peripheral devices. USB ports began to appear on PCs in 1997, and Windows 98 was the first Windows to support it natively. Within a few years, USB became popular for connecting nearly every external peripheral device. Replacing the serial and parallel ports on a PC, at least four USB ports are standard on every computer.Hot SwappableUSB devices can be connected to without turning the computer off, enabling removable devices to be plugged and unplugged as needed. This feature, combined with easy-reach ports on the front of the computer case, gave rise to the ubiquitous USB drive.USB 1.0 and USB 2.0USB has a maximum bandwidth of 12 Mbps for USB 1.0 and 1.1 and 480 Mbps for Hi-Speed USB 2.0. Up to 127 peripheral devices can be attached to the bus, and USB 1.1 devices can plug into USB 2.0 ports. Fast devices can use the full bandwidth, while low-speed ones can use a 1.5 Mbps sub channel.
