Abstract

Reflective display technology is very important for electronic paper (e-paper) displays, as it will create images and need no power to hold images (bistability nature). With the advantage above, more and more applications of color e-paper displays appeared in the market. For the convenience of reading, some of e-paper displays are equipped with a front light. In this chapter, suitable measurement methods are proposed to evaluate the color and correlated optical properties of e-paper displays under the condition whether the front light is on or off.

Abbreviations

DUT:

Display under test

EPD:

e-Paper display

ILU:

Integrated lighting unit (e.g., an edge-lit front light plate)

LMD:

Light-measuring device

Bistability:

Ability to hold the image without applied voltage.

Contrast ratio:

Ratio of the DUT brightness at white state to that at black state.

Gamut area:

Area enclosed by the chromaticity coordinates of the display primary colors.

Gamut area ratio:

Ratio of the gamut area to the area defined by a particular specification in a color space coordinate.

Uniformity:

Characterizes the change in brightness or color difference over the display area of the DUT.

Viewing direction:

Direction from which the observer looks at the point of interest on the DUT. Viewing direction dependence characterizes the change in brightness, contrast ratio, and color relative to their values at the normal viewing direction.
