  • Patent number: 8305353
    Abstract: A glare-resistant touch panel has a touch-sensing layer, a polarizing filter, a diffraction layer and an anti-reflection layer. The polarizing filter is mounted on the touch-sensing layer. The diffraction layer is mounted on the polarizing filter and splits lights into different polarized angles. The anti-reflection layer is mounted on the diffraction layer. With the diffraction layer, light polarized at a specific angle are split to be polarized at different angles and are allowed to partly pass through polarized sunglasses. Hence a sunglasses wearer can still see what the screen from the touch panel displays even if the sunglasses and the polarizing filter are oriented perpendicular to each other.
