Optical effects of anti-glare films on a dual-view display

The effects of different anti-glare films on an 8-inch dual-view display were investigated. To quantify the display performance, the image sharpness, speckle, and crosstalk were evaluated. The image sharpness and sparkle were first measured, and the obtained values were compared with the results of a jury appraisal for devising acceptance levels. For image sparkle, it was found that the standard deviation for the individual pixel luminance must be less than 40 to be acceptable to the user. Finally, it was found that the crosstalk of the display needs to be less than 0.5 to be unnoticeable and less than 1.0 to be acceptable.
