[0023] Hereinafter, a plurality of embodiments of the present invention will be disclosed with reference to the drawings. For the sake of clarity in the description, many practical details will be explained in the following description. However, as will be understood by those skilled in the art, these practical details are not essential in some embodiments of the present invention and do not limit the present invention. Also, for the sake of simplifying the drawings, some of the known structures and members are shown schematically in a simplified manner. Furthermore, considering the visibility of the reader, the dimensions of each member in the drawings may be different from the actual dimensional ratios.

[0024] FIG. 1 is a perspective view of a transmission device 100 for wireless projection according to an embodiment of the present invention. FIG. 2 is a block diagram of the transmission device 100 for wireless projection in FIG. 1. As shown in FIGS. 1 and 2, the transmission device 100 for wireless projection includes a housing 110, a transmission line 120, an operation circuit module 130, a signal transmission / reception unit 140, a display screen 150, and a command input interface 160. The operation circuit module 130 is fixed within the housing 110 and is electrically connected to the transmission line 120. The transmission line 120 is coupled to one end of the housing 110 and extends outward from the housing 110. The signal transmission / reception unit 140 is fixed within the housing 110 and is electrically connected to the operation circuit module 130 by being coupled to the operation circuit module 130. The display screen 150 is attached to the housing 110 and is electrically connected to the operation circuit module 130. The command input interface 160 is located on the housing 110 and is electrically connected to the operation circuit module 130.

[0025] In this embodiment, for example, the housing 110 is a substantially rectangular body and includes two main surfaces 111 and a plurality of side surfaces 112. These main surfaces 111 face each other. Each main surface 111 is adjacent to and surrounded by these side surfaces 112. Each side surface 112 is smaller than each main surface 111. The display screen 150 is located on one of the main surfaces 111. In particular, the display screen 150 completely covers the main surface 111 of the housing 110. However, the present invention is not limited thereto. In other embodiments, the display screen 150 may be arranged to be located on one of the side surfaces 112, or simultaneously on the main surface 111 and the side surface 112 adjacent to each other. Further, the present invention is not limited to the outer shape of the housing 110, and the main surface 111 and the side surface 112 of the housing 110 are not limited to being a flat surface or an arc surface.

[0026] For example, the command input interface 160 includes a touch panel. The touch panel is translucent and is covered over the display area of the display screen 150, so that the touch panel and the display screen 150 together form a known touch screen. That is, both the display screen 150 and the command input interface 160 are located on the same surface of the outer shell 110. However, the present invention is not limited to the form and position of the command input interface 160. In other embodiments, for example, the command input interface 160 may be located beside the display screen 150 and may be represented in at least one form of, for example, a trackball, a tap button, and a touch pad. Alternatively, the command input interface 160 and the display screen 150 may be disposed on different surfaces of the outer shell 110 respectively.

[0027] The operation circuit module 130 includes a wiring board 131, an image processing unit 132, and a central control unit 133. The wiring board 131 is fixed within the outer shell 110. The image processing unit 132 is fixed to one surface of the wiring board 131 and is used to process the image signals received from the outside. The central control unit 133 is fixed to the wiring board 131 and is respectively coupled to and electrically connected to the image processing unit 132, the signal transceiver unit 140, the display screen 150, and the command input interface 160, and is used to control the normal operations of the image processing unit 132, the signal transceiver unit 140, the display screen 150, and the command input interface 160. The image processing unit 132 is, for example, a GPU card or a GPU chip, etc. The central control unit 133 is, for example, a CPU or a single chip, etc.

[0028] For example, the transmission line 120 includes a first conductor 121 and a connector 122. One end of the first conductor 121 extends into the outer shell 110 and is fixedly welded to a signal connection pad (not shown) of the wiring board 131. The connector 122 is located at one end of the first conductor 121 facing the outer shell 110 and is removably connected to an external device (such as a signal source device).

The electrical connection port 320 is disposed on the device host 310 and is electrically connected to the device host 310.

[0030] In this way, when the connector 122 of the transmission line 120 is detachably connected to the electrical connection port 320 of the signal source device 300, the wireless projection transmitter 100 is electrically connected to the device host 310. Subsequently, the signal transmission / reception unit 140 identifies one or more receiving-side devices 400 and other operation functions 202 (such as up / down direction, addition, deletion, or modification, etc.) in a wireless manner, the display screen 150 displays at least one projection option list 200 (FIG. 4), and the projection option list 200 includes the numbers 201 (FIG. 4) of these receiving-side devices 400 for the user to browse and select one by one. Therefore, the operation circuit module 130 processes the image signal provided by the device host 310 and transmits the image signal to the receiving-side device 400 selected via the signal transmission / reception unit 140.

[0031] In this embodiment, the signal transmission / reception unit is a wireless transmission unit (such as a WIFI or Bluetooth (registered trademark) transmission element) and can be connected to the signal source device 300 in a wireless manner, but the present invention is not limited thereto.

The receiving-side device 400 is, for example, a television, a projector, or other similar mobile devices, but the present invention is not limited thereto.

[0032] Also, when the signal source device 300 is not a computer device, the signal source device 300 does not necessarily have a display device 330 and has only one display output interface (not shown). The display output interface is disposed on the device host 310 and is electrically connected to the device host 310 and is used to detachably connect the display device 330.
