[0027] Please refer to FIG. 2, which shows a block diagram of a wireless network projector. The wireless network projector 200 includes: a microprocessor 202 , a wireless network base station module 201 , a projection module 205 , a plurality of signal receiving units, a transmission line 209 and an image signal line 210 . The wireless network base station module 201 is electrically connected to the microprocessor 202 . The projection module 205 is also electrically connected to the microprocessor 202 . Through the image signal line 210 , the user can transmit the computer screen to the microprocessor 202 , and through the projection module 205 , the wireless network base station module 201 projects the received computer screen onto a screen.

[0028] The signal receiving units are, for example, the signal receiving unit 207a of the RGB connector, the signal receiving unit 207b of the DVI connector, the AV terminal signal receiving unit 207c, and the S terminal signal receivi...

[0035] Please refer to FIG. 2 . What is different from the first embodiment is that the two-way communication between the wireless network base station module and the microprocessor is through the transmission line. The function of the station module 201 is notified to the microprocessor 202. This method judges whether there is a user using the wireless network base station module 201 by the voltage level of the connector pin (Pin) between the microprocessor 202 and the wireless network base station module 201 . For example, if someone connects to the wireless network base station module 201 , the voltage level of a certain pin of the wireless network base station module 201 is changed and transmitted to the microprocessor 202 through the image signal line 210 . The microprocessor 202 can detect the change of the voltage level, and set the current signal receiving unit as the wireless network base station module 201 . On the contrary, if no one is connected, the microprocesso...

Abstract

The invention is a wireless network projector, comprising a microprocessor, a wireless network base station module, a projection module and several signal receiving units, where the wirelss network base station module comprises at least an image signal line connected to the microprocessor; the projection module is connected to the microprocessor to project a picture; the microprocess determines whether there is a user connected to the wireless network base station module to determine whether to scan the other signal receiving units; and it can make the microprocessor able to detect and differentiate signals from different sources.

Description

technical field [0001] The present invention relates to a projector, and in particular to a wireless network projector. Background technique [0002] Current wireless network projectors use a built-in or external wireless network base station module to transmit or receive signals. Please refer to FIG. 1A , which shows a block diagram of a wireless network base station module and a projection module. The wireless network projector 100 includes: a wireless network base station module 101 , a microprocessor 102 , a projection module 105 and various signal receiving units 107 . The wireless network base station module 101 receives a picture, and sends it to the projection module 105 via the microprocessor 102 to play the picture. The different signal receiving units are, for example, RGB, DVI, AV terminal or S terminal. The RGB signal receiving unit is used for receiving analog image signals, and the DVI signal receiving unit is used for receiving digital image signals. The ...
