[0018] In order to make the technical features, objects and effects of the present invention more clearly understood, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] As shown in FIG. 1, in a first embodiment of the wireless touch Bluetooth reverse control system of the present invention, the wireless touch Bluetooth reverse control system 10 includes at least a first electronic device (not shown) and a second electronic device (not shown).

[0020] Specifically, at least a touch control board 300 and a touch screen 400 are disposed on the first electronic device (for example, a portable display screen or a mobile display screen).

[0021] The touch control board 300 and the touch screen 400 are used to sense and obtain operational controls for operation.

[0022] Furthermore, the second electronic device (e.g., a mobile phone, a tablet, a computer, or a cloud computer) wirelessly connects to the first electronic device (e.g., a portable display screen or a mobile display screen) via the wireless screen projection panel 100 or the Bluetooth module 200, establishes a signaling channel, and transmits the screen projection image to the first electronic device (e.g., a portable display screen or a mobile display screen).

[0023] In addition, the first electronic device (e.g., a portable display screen or a mobile display screen) and the second electronic device are both equipped with a Bluetooth module 200 and a WIFI circuit (belonging to the wireless screen projection panel 100), and the two are paired and connected through the transmitting and receiving ends of the Bluetooth module 200 to realize short-range wireless communication.

[0024] Specifically, by operating the touch control board 300, the sensed operation control command is output to the second electronic device via the Bluetooth module 200, and the first electronic device operates and controls the image displayed on the second electronic device (e.g., a mobile phone, a tablet, a computer, or a cloud computer), and the first electronic device (e.g., a portable display screen or a mobile display screen) sends an operation command to the second electronic device based on the operation control.

[0025] The second electronic device (e.g., a mobile phone, a tablet, a computer, or a cloud computer) performs a corresponding operation based on the input operation command, and the second electronic device (e.g., a mobile phone, a tablet, a computer, or a cloud computer) transmits the screen projection image after performing the corresponding operation to the first electronic device (e.g., a portable display screen or a mobile display screen) through a signaling channel, and further realizes the reverse operation control of the first electronic device (e.g., a portable display screen or a mobile display screen) to the second electronic device (e.g., a mobile phone, a tablet, a computer, or a cloud computer).

[0026] For example, a user can project the display interface of a second electronic device (e.g., a mobile phone, tablet, computer, or cloud computer) onto a first electronic device (e.g., a display screen) using wireless screen projection technology (Bluetooth module 200 or WIFI circuit), and then operate the display interface of the second electronic device displayed on the first electronic device through a touch screen on the first electronic device to control the second electronic device (e.g., a mobile phone, tablet, computer, or cloud computer) in reverse, thereby realizing the multi-screen collaboration function and viewing and using the mobile phone, tablet, computer, or cloud computer on the first electronic device.

[0027] When a user operates the display interface of a mobile phone, tablet, laptop or computer displayed on the first electronic device through the touch screen on the first electronic device (for example, the user clicks, drags or performs other operations on the APP, control or software on the display interface of the mobile phone, tablet, computer or cloud computer displayed on the first electronic device by touching the touch screen), the first electronic device receives the command corresponding to the user's operation sent by the touch control board 300, packages the processed operation command, and sends it to the mobile phone, tablet, computer or cloud computer through a signaling channel, so that the mobile phone, tablet, computer or cloud computer responds after receiving the operation command.

[0028] When a user controls a mobile phone, tablet, computer, or cloud computer that projects a screen in the reverse direction through a first electronic device that projects a screen, the first electronic device that projects a screen needs to receive the user's operation, process the user's operation, and transmit the user's operation command to the electronic device that projects a screen, so that the electronic device that projects a screen responds according to the command.

[0029] For example, a user can click on an icon of an application program on the screen-projected desktop of a mobile phone, tablet, computer, or cloud computer on the first electronic device and reversely control the mobile phone, tablet, computer, or cloud computer to open the corresponding application program.

[0030] Using this technical solution, the second electronic device wirelessly connects to the first electronic device through a Bluetooth module to establish a signaling channel, and the first electronic device operates and controls the screen-projected image sent by the second electronic device and transmits operation commands to the second electronic device, thereby realizing reverse control of the second electronic device. This effectively solves the problem that in order to realize reverse control of a mobile phone, tablet, computer or cloud computer, the electronic device whose screen is to be projected and the mobile phone, tablet, laptop or computer need to be connected by a Type-C or data cable, but the length of the Type-C or data cable limits the user's usage scenarios and results in a poor user experience.
