Improved Visibility Display Device using an Index-Matching Scheme

摘要

Display module (10) for use in an electronic device, comprising a front window (12) and a display unit (13,100), wherein an intermediate layer (24) of a transparent material is sandwiched between said front window (12) and the display unit (13,100). The intermediate layer (24) being formed by a material selected in dependence of the material of the front window (12) in order to minimize reflection in the interface between said front window (12) and said intermediate layer (24). The intermediate layer (24) consists of one or more layers whose refractive indices are chosen so that they closely match the refractive indices of the front window or the display unit.
