In recent years, the flat-panel display (FPD) technology has undergone great development. Currently, FPDs are present
in many devices. A significant element in FPD manufacturing is the display front surface. Manufacturers sell FPDs with
different types of front surface which can be matte (also called anti-glare) or glossy screens. Users who prefer glossy
screens consider images shown in these types of displays to have more vivid colours compared with matte-screen
displays. However, external light sources may cause unpleasant reflections on the glossy screens. These reflections can
be reduced by a matte treatment in the front surface of FPDs. In this work, we present a method to characterize the front
surface of FPDs using laser speckle patterns. We characterized three FPDs: a Samsung XL2370 LCD monitor of 23"
with matte screen, a Toshiba Satellite A100 laptop of 15.4" with glossy screen, and a Papyre electronic book reader. The
results show great differences in speckle contrast values for the three screens characterized and, therefore, this work
shows the feasibility of this method for characterizing and comparing FPDs which have different types of front surfaces.
