Patent ID: 8274631

Claim:
A reflective functional part integrated display comprising: a liquid crystal display module defining vertical and horizontal axes and having a module front surface, said liquid crystal display module comprising, from front to rear, a liquid crystal cell comprising a liquid crystal layer sandwiched between two transparent electrodes, a first linear polarizer having a first linear polarization axis, and a backlight module; a first retarder layer forward said liquid crystal display module, said first retarder layer having a front surface, a rear surface, a retardance of about (2n+1)λ/4, and a first slow axis, which forms an angle θ 1 to said first linear polarization axis, where n is an integer and λ is a wavelength and is between about 400 nm to 700 nm; a reflective functional part forward said first retarder layer, said reflective functional part having a rear surface and comprising at least one of a touch panel, an EMI shield, an infrared filter, and an LCD heater; a second retarder layer forward said reflective functional part, said second retarder layer having a second slow axis and a retardance of about (2m+1)λ/4, where m is an integer and λ is a wavelength and is between about 400 nm to 700 nm; a second linear polarizer forward said second retarder layer, said second linear polarizer having a second linear polarization axis, which forms an angle θ 2 to said second slow axis of said second retarder layer; and a display front surface through which light from said backlight module exits, wherein θ 2 is between about 25° to about 65° and said second linear polarization axis is set at about 90 degree with respect to said first linear polarization axis, and wherein θ 1 is between about −25° to about −65° when (m+n) is zero or an even integer, or θ 1 is between about +25° to about +65° when (m+n) is an odd integer.
