OUTDOOR DISPLAY APPARATUS

摘要

An outdoor display apparatus includes a housing having an opening, an inlet port and an outlet port, a transparent member disposed in tile opening, a liquid crystal display panel module 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, a circuit disposed at a rear of the liquid crystal display panel module, an optical film disposed inside the transparent member at a position corresponding to the liquid crystal display panel, and an air circulation device 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.

主权项

1. An outdoor display apparatus comprising:
a housing having an opening formed at a front portion thereof, an inlet port through which air is introduced, and an outlet port through which air is discharged; a transparent member disposed in the opening; a liquid crystal display panel module disposed in the housing, spaced apart from the transparent member to define a gap therebetween, and provided with a liquid crystal display panel at a front side thereof to display an image; a circuit disposed at a rear portion of the liquid crystal display panel module; and an optical film disposed inside the transparent member at a position corresponding to the liquid crystal display panel of the liquid crystal display panel module; wherein the optical film is disposed on an inner surface of the transparent member and comprises a polarizing film having an optical axis the same as an optical axis of light passing through the liquid crystal display panel and a ¼ wavelength plate to convert an optical axis of an image displayed on the liquid crystal display panel into circular polarized light.
