The radio frequency wireless module can be integrated into the CPU main board. In the circuit board, it can also be ... connected to the main board of the CPU in the form of eight or or PCI cards and through the slots of PCMCIA or CF or PCI. It can also be a daughter card type and through a The slot is electrically connected to the CPU main board. When the radio frequency wireless module of the CPU main board and the radio frequency wireless module 20 is of the type of PCMCIA or CF or PCI card, and when the radio frequency wireless module # is not inserted in the wireless display, the wireless display can pass through The connector 70 is used to receive the screen signal transmitted by the connector 8 M240731. When the radio display is inserted with the radio frequency wireless module, the radio display can pass through the c PU main board and the radio frequency wireless module on it. 2 0 to receive the screen signal transmitted by the dock through radio frequency. The signal detection device 30 is coupled to the first and second input ports of the signal selection device 10 to generate a selection signal 31. The signal selection device 10 selects the first or second input port as its output. It can detect the HSYNC signal line or VSYNC signal line of the first input port of the signal selection device 10, and calculate a specific time by a timer to determine whether there is an HSYNC signal or a VSYNC signal on the HSYNC signal line or VSYNC signal line . If the HSYNC signal or VSYNC signal is detected within a certain period of time, it can be determined that the first input port of the signal selection device 10 has a screen signal. At this time, a selection signal 31 is generated, and the signal selection device 10 selects The first input port is its output. If the HSYNC signal or the VSYNC signal cannot be measured within a specific time, it can be determined that the first input port of the signal selection device 10 has no screen signal, and the selection signal is now selected. 3 1 Disable. The signal selection device 10 selects the second input as its output. The signal detection device 30 also detects the HSYNC signal line or the VSYNC signal line of the second input port of the signal selection device 10 in the above manner. If the HSYNC signal or the VSYNC signal cannot be measured within a specific time, Then it can be judged that the signal 9 M240731 selects the second input port of the device 10 and there is no screen signal. At this time, a power-off signal 32 is generated, and the CPU main board and the radio frequency wireless module 20 enter the power-off mode. When the screen signal of the second input Keyboard is used, the Keyboard / Mouse function on the CPU main board can be used, and the Keyboard / Mouse can be connected to the CPU main board via the connectors 103 and 104. The enlargement / reduction device 40 (Scalar) 'is coupled to the output of the signal selection device 10 to enlarge / reduce the screen signal (Up-Scaling / Down-Scaling), so that screens with different frequencies and resolutions cannot be displayed. The signal is displayed correctly on the panel. The driving circuit 50 drives the screen panel 60 according to the signal output from the enlargement / reduction device 40. The screen panel 60 displays the screen signal transmitted from the outside or the CPU main substrate and The screen signal transmitted by the RF wireless module 20, the screen panel 60 can be an LCD panel, which is easy to carry when separated from the base. In this creation, a backup battery 80 is also included. When the wireless display is moved and disconnected from the power supply or when the power is cut off momentarily, it can provide power to the CPU main board and the RF wireless module to enter the sleep state to increase the convenience of use. As can be seen from the above, this creation uses a CPU main substrate and a radio frequency wireless module 20 to separate the wireless display from the connector, not only to display normally, but also to display at any location as the wireless display moves, increasing Ease of use. 10 M240731 In summary, regardless of the purpose, method and effect, this creation shows its characteristics that are quite different from the known technology. It is a highly practical creation. I implore your reviewers to make a clear observation and grant the patent at an early date. , Jia Jiahui society, I really feel virtuous. However, it should be noted that the above-mentioned embodiments are just examples for the convenience of explanation.
