Quarter Video Graphics Array (QVGA)

QVGA (Quarter Video Graphics Array) is a small-screen display mode in which the resolution is 320 pixels horizontally by 240 pixels vertically (320 x 240). This is 25 percent of the total number of pixels afforded by the VGA (Video Graphics Array) display mode originally introduced by IBM in 1987. Because the display on small-screen devices is frequently greater in height than width, QVGA resolution is sometimes expressed as 240 x 320.

QVGA displays are used in small computers and consumer electronic devices such as personal digital assistants (PDAs), cellular telephones, digital cameras, camcorders, handheld game consoles, portable MP3 players and portable electronic test equipment. Liquid crystal display (LCD) panels with the QVGA specification offer full color-viewing. Some QVGA displays are equipped with touch screen capability.
