5. Combined protective anti-reflection filters

In modern aviation universal protective anti-reflection filters (PAF) performing several functions simultaneously are in demand.

Most important PAF functions are:

  • EMI shielding

  • Front heating of LCD

  • Image contrast enchancement

  • Low specular front and back reflection

  • Low diffuse front and back reflection

1. A schematic representation of PAF wich provides EMI shielding and LCD front heating function (PAF-EMI-N) is shown in Fig. 1, external view in Fig. 2, general characteristics are shown in table 1 .

An example is given for LQ040Y3DX80B Sharp LCD module.

2. A schematic representation of PAF wich provides EMI shielding and image contrast enchancing (PAF-EMI-K) is shown in Fig. 2, external view in Fig. 4, general characteristics are shown in table 2 .

An example is given for LG LCD module of the B11 series.
