DISPLAY DEVICES HAVING AN ANTIGLARE LAYER PROVIDING REDUCED SPARKLE APPEARANCE

摘要

A display device and an anti-glare layer that minimize the phenomenon of glare and glare are described. One type of display device includes a pixel substrate with a pixel array, and an anti-glare layer. The anti-glare layer has a spatial frequency such that the reference focal length of the anti-glare layer is at least four times larger than the surface of the pixel array and the anti-glare interlayer optical distance, or at least three times smaller than the surface of the pixel array and the anti- Surface roughness. In some embodiments, the pixel pitch of the pixel array is less than 120 占 퐉. In some embodiments, the anti-glare layer has an elliptical power spectral density with a minor axis parallel to the color direction of the pixel array.
