What is QVGA (Quarter VGA)? An easy-to-understand explanation of the basic concepts of display technology
When it comes to display technology, there are various terms and acronyms floating around. One of them is QVGA, which stands for Quarter VGA. In simple terms, it refers to a display resolution that is one-fourth the resolution of the VGA (Video Graphics Array) standard.
To understand QVGA better, let’s first explain what VGA is. VGA is a display standard that was introduced in the late 1980s, and it quickly became the most common resolution for computer displays. It has a resolution of 640 pixels horizontally by 480 pixels vertically, resulting in a total of 307,200 pixels.
Now, if VGA has a resolution of 640×480 pixels, QVGA reduces that resolution by a quarter. This means a QVGA display has a resolution of 320 pixels horizontally by 240 pixels vertically, giving a total of 76,800 pixels. As a result, QVGA displays are typically smaller in size compared to VGA displays.
QVGA has been widely used in various devices, especially in the early days of mobile phones and handheld gaming consoles. It provided a decent level of resolution while also being more accessible due to the technology limitations of the time. However, with advancements in display technology, QVGA has become less common in recent years, giving way to higher-resolution displays like HD and 4K.
It’s important to note that QVGA is just one of many display resolutions that exist today. There are numerous other standards and resolutions, each tailored to specific use cases and devices. From low-resolution displays for simple devices to ultra-high-definition screens for professional applications, the world of display technology is vast and ever-evolving.
In conclusion, QVGA, or Quarter VGA, refers to a display resolution that is a quarter of the VGA standard. While it may not be as prevalent as it once was, QVGA played a significant role in the development of display technology, particularly in early mobile devices. It’s just one piece of the puzzle in the wide array of display resolutions available today.
