Quantum Extended Graphics Array. It is a display mode in which the resolution is 2048 pixels horizontally by 1536 pixels vertically (2048 x 1536). This results in 3,145,728 pixels in the image. A QXGA display might be preferred by computer users who want or need extreme detail, or who want to view multiple images on a single screen. Advanced projection systems use QXGA to obtain images that appear crisp even when enlarged to dimensions such as those used in presentations.
昆腾扩展图像序列。分辨率达到水平2048像素,垂直1536像素(2048 x 1536)的显示器模式,这使得图像有3,145,728个像素。需要极其细节的或者需要在一个屏幕上查看多个图像的计算机用户会喜欢QXGA。高级
投影系统使用QXGA来使得图像放大到很大(例如做演说的时候)仍然保持清晰。
目前苹果公司发布的new ipad、ipad4和NEW MAC BOOK PRO产品中所使用的retina屏幕应用的就是这种技术,这种屏幕技术使得整块屏的显示显示效果达到了一个相当高的细腻程度,像素密度达到326像素/英寸(ppi)。
