IPS display tech

Overview

IPS = "In=Plane Switching"

IPS panel layers (top-to-bottom)

  • glass surface - protects the layers below. The glass may be smooth and glossy or it can be etched so that it provides both anti-glare effects as well as some physical texture or a drawing tablet pen

  • Front polarizing filter - polarizes light in the other direction (i.e. horizontally)

  • Color filter glass substrate - r,g,b filters aligned to the sub-pixels in the TFT glass substrate. Light going up from here now have color

  • Liquid crystal layer - Controls which subpixels can be seen by selectively controlling what light below passes through.

  • TFT glass substrate - thin sheet of glass with microscopic circuitry with sub-pixels, light from below passes up through layer.

  • Rear polarizing filter - polarizes light in one direction (i.e vertically)

  • Diffuser and Prism films

  • Light Guide Plate - Evenly distributes the light from the BLU across the entire screen

  • Backlight Unit (BLU) - LED lights provide illumination
