Contrast and color rendering of Liquid Crystal Display (LCD) is highly sensitive to the angle at which it is viewed.
To overcome this issue, image enhancing films – retarders – are used.

Different characteristics and combinations of retarders are used depending on the LCD mode – Vertical Alignment, In-Plane Switching, etc.

LCD optical stack

In the general case a typical LCD optical stack includes some number of retarders situated around the LC cell.

Using retarders as part of the optical stack results in dramatic improvement of viewing characteristics of a LCD.

Effect of compensating a LCD using Crysoptix coatable TBF™ materials can be illustrated via simulated optical performance of a display with and without retarders.

Accurate simulation of optical performance of a LC screen provides crucial guidance on the required characteristics of retarders needed to achieve better viewing angle and color rendering of the screen.
