STN displays improved on that by twisting the liquid crystal molecules at a much greater angle, typically between 180 and 270 degrees. This allows for a sharper image and passive matrix addressing , a simpler way to control the pixels in an LCD.
Various computer display standards or display modes have been used in the history of the personal computer. They are often a combination of aspect ratio (specified as width-to-height ratio), display resolution (specified as the width and height in pixels ), color depth (measured in bits per pixel), and refresh rate (expressed in hertz ).
A comparison between a blank passive-matrix display (top) and a blank active-matrix display (bottom). A passive-matrix display can be identified when the blank background is more grey in appearance than the crisper active-matrix display, fog appears on all edges of the screen, and while pictures appear to be fading on the screen.
DSTN (double super twisted nematic), also known as dual-scan super twisted nematic [1] or simply dual-scan, is an LCD technology in which a screen is divided in half, which are simultaneously refreshed giving faster refresh rate than traditional passive matrix screens. [2]
Different display technologies have vastly different temporal characteristics, leading to perceptual differences of motion, flicker, etc. Sketch of some common display technologies' temporal behaviour. The figure shows a sketch of how different technologies present a single white/grey frame. Time and intensity is not to scale.
Currently, the only display technology capable of multi-syncing (displaying different resolutions and refresh rates without the need for scaling). [50] Display lag is extremely low due to its nature, which does not have the ability to store image data before output, unlike LCDs, plasma displays and OLED displays. [51]

The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.
