Abstract: The invention relates to a display rear shell with waterproof and fireproof properties comprising a main layer of a pulp made from hardwood in an amount from 80% to 90% by weight of the main layer, a pulp waterproof composition in an amount from 5% to 15% by weight of the main layer, and a flame retardant in an amount of a remaining weight percentage by weight of the main layer, a fireproof layer and a waterproof layer, in place of a traditional plastic display rear shell using plastic materials for characteristics as waterproof, fireproof and light weight.

Abstract: The invention relates to a display connector with a 4K image resolution. It primarily comprises a first connector, a second connector and a third connector. The present invention is a connector for a display to support high specification images with quad full high definition (QFHD). The third connector is used to connect an existing video playback device merely having the playback function of full high definition (FHD). Then the FHD image data is upscaled through an electrically connected image upscaling module of the first connector, and QFHD image signals with an ultra-high definition resolution is displayed through an electronic display device. Accordingly, the QFHD image signals with the ultra-high definition resolution can be displayed without upgrading the hardware of the player or computer so as to dramatically reduce the required cost of upgrading the hardware.

Abstract: A rotary lighting fixture having a speaker with a playback function is revealed herein, comprising a shell having an opening, a speaker fitted inside the shell, and an annular LED module having plural LEDs fitted at the opening of the shell for illumination and playback functions. In addition, the lighting fixture also combines with a power supply base with a rotary function embedded in a ceiling and a wall for substantially saving space in use thereof, promoting interior designs by its aesthetic appearance and adjusting angles of incidence from the LEDs as desired.

Abstract: The invention relates to a LED display device. Primarily, it comprises a liquid crystal display, a shell, a plurality of lighting modules and two reflective layers. The present invention is a liquid crystal display device which uses the light emitting diode to combine with polymethylmethacrylate (PMMA) as a lighting module. The secondary lens theory composed of different refractive index between air and PMMA and the angle of the reflective layers on the inner surface of the side planes are used to effectively increase the refracted angle of light emitted from the light emitting diode and the distance of the mixed light and to effectively reach the advantages of thinner liquid crystal display and lower power consumption.
