The Quarter Video Graphics Array (also known as Quarter VGA or QVGA) is a popular term for a computer display with 320x240 resolution. QVGA displays are most often seen in mobile phones and PDAs. Most often the displays are portrait mode(other mode is landscape) and are referred to as 240x320 as the displays are taller than they are wide.
The name is derived from the fact that it offers 1/4 of the 640x480 maximum resolution of the original IBM VGA display technology, which became a de facto industry standard in the late 1980s. QVGA implementations are not compatible with, nor directly derived from, standard VGA chipsets or interfaces; the term refers only to the display's resolution.

QVGA displays are most often seen in mobile phones, PDAs and some handheld game consoles.
The QVGA term is also seen in digital video recording equipment as a space-efficient mode, typically in multi-function devices that are also still digital cameras (such as the Fujifilm FinePix S602) or mobile phones (such as the Pantech PH-L4000V, Samsung SGH-D600).
QVGA video is typically 15 or 30 frames per second.
(QVGA stands for Quarter VGA, or 240x320 resolution, in case you're not hip with the lingo).
Now that I can see the pipeline of handsets filling up with QVGAscreens, I can really say without a doubt that they are going to make fundamental improvements in mobile usability and thus higher usage.
That's a QVGAscreen, and it's caused a complete industry wide landrush into portable video as a result.
