摘要:
An outdoor display apparatus includes a housing (10) having an opening (10a), an inlet port (10b) and an outlet port (10c), a transparent member (20) disposed in the opening, a liquid crystal display panel module (30) disposed in the housing so that the liquid crystal display panel module is spaced from the transparent member to define a gap therebetween, the liquid crystal display panel module being provided at a front thereof with a liquid crystal display panel (31) to display an image, a circuit (33) disposed at a rear of the liquid crystal display panel module, an optical film (21,22) disposed inside the transparent member (20) at a position corresponding to the liquid crystal display panel of the liquid crystal display panel module, and an air circulation device (40) to distribute air introduced through the inlet port so that the distributed air passes through the gap between the transparent member and the liquid crystal display panel and through the circuit and is discharged through the outlet port. The optical film comprises a linear polariser (21) and a 1/4 wavelength plate (22) for preventing the contrast being lowered by ambient light.

摘要:
A stereoscopic imaging system to prevent deterioration in brightness and optical characteristics due to deviation of an optical axis upon formation of a stereoscopic image is provided. The stereoscopic imaging system includes a stereoscopic image display device to output linearly polarized light, a phase difference plate provided at a front surface of the stereoscopic image display device and which converts the linearly polarized light output from the stereoscopic image display device into circularly polarized light, and liquid crystal shutter glasses having a phase difference plate attached to a front surface thereof and which restores the circularly polarized light having passed through the phase difference plate into the linearly polarized light. Upon formation of a stereoscopic image, the liquid crystal shutter glasses may restore light output from the stereoscopic image display device without loss.
