Projection device

Abstract

A projection device, including a projection module, a control unit, a cases, a wireless receiver unit and a control panel. Projection module suitable for projection is imaged to the screen, and control unit with the projection module, connectivity to control the projector module. Chassis suited to accommodate projection modules and control modules, and chassis, with exposure to a slot. Wireless receiver modules in the chassis configuration, and control unit with electrical connections, and control panel is removable to place slot in the card. When the control panel is in the exact place, the control panel are the control unit and electrical connections, and provide a suitable control panel signal to the control unit to control the projector module. When the control panel and the exact separation, control panels suitable for providing a wireless signal to a wireless receiver unit to control the projector module.

Description

technical field [0001] The present invention relates to a display device, and in particular to a projection device. Background technique [0002] With the advancement of modern video technology, projection devices have been widely used in occasions such as home theaters and conference reports. In order to increase the operation convenience of the projection device, generally the projection device is equipped with an infrared remote controller, so that the user can remotely control the projection device from a distance. [0003] FIG. 1A is a three-dimensional schematic diagram of a conventional projection device, and FIG. 1B is a structural block diagram of the projection device in FIG. 1A . Please refer to FIG. 1A and FIG. 1B , a conventional projection device 100 includes a projection module 110 , a control unit 120 , a housing 130 , a control panel 140 , an infrared receiving unit 150 and an infrared remote controller 160 . The projection module 110 is used to project im...

AI Technical Summary

Problems solved by technology

[0005] When the projection device 100 needs to be stored after use, since the infrared remote control 160 and the casing 130 are separate components, it is relatively difficult to store.

In addition, users often place the infrared remote controller 160 at hand after using it, and the infrared remote controller 160 is small in size, so it is easy to cause the infrared remote controller 160 to be difficult to find and lost.
