Detailed ways

In order to make the technical problem solved by the utility model, the technical scheme adopted and the technical effect achieved clearer, the technical scheme of the embodiment of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiment is only Some embodiments of the utility model, but not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present utility model.

Please refer to FIG. 1 , which is a schematic structural diagram of a full-touch all-in-one machine provided in a specific embodiment of the present invention. The full-touch all-in-one machine in this embodiment is mainly used for various content display during information dissemination, such as classrooms, auditoriums, information release, forums, etc., to facilitate content presentation by the speaker and support the speaker's speech content. As shown in the figure, the all-touch all-in-one machine includes a display screen and a touch device covered on the touch display screen, and also includes a TV motherboard, a gesture recognition circuit for recognizing gestures detected by the touch device, and a circuit for receiving A gesture function forwarding device for TV control commands generated by the gesture; the touch device is connected to the input end of the gesture recognition circuit, and the output end of the gesture recognition circuit is connected to the input end of the gesture function forwarding device. The output end of the gesture function forwarding device is connected with the control input end of the TV main board.

For the existing TV motherboard, it does not have the data processing capability of the smart operating system (such as Android/Windows/Mac), so its use and control process is relatively simple compared with the smart operating system, for example, it cannot recognize more complex gesture operations .

During the use of the display screen, in order to adapt to different environments and different users, the display parameters of the display screen may be set. In the prior art, the setting process is basically realized by means of mechanical buttons or area touch. Gesture control is not possible.

In this solution, the touch device uses two output signals to output to the main board of the TV and the gesture recognition circuit respectively, correspondingly realizing normal touch and gesture touch respectively.

Normal touch: Match the physical size of the touch sensing device with the display screen, and perform a touch function on the same physical position in the content display area by means of normal touch. A low-level occlusion signal. When the TV main board receives this signal, perform an operation through the corresponding physical location of the OSD interface, such as selecting the image parameter setting in the OSD menu, and you can select its parameter setting content through normal touch.

Gesture touch: First, physically divide the gesture function area corresponding to the content display area of the display screen. When the touch body performs a gesture function in one of the gesture function areas, the touch sensing device will transmit the corresponding received occlusion signal to the gesture recognition Circuit, the current channel will keep a low state within a cycle to block the channel signal, and then the signal will be transmitted to the gesture function receiving module through the gesture recognition circuit, and the corresponding command code will be transmitted to the TV main board, and the TV main board will compare the command code content, and correspondingly pop up the OSD interface of the corresponding area.

By adding a gesture recognition circuit, the gesture detected in the touch device is generated into a TV control command that can be recognized by the TV main board, and the TV control command is sent to the TV main board through the gesture function forwarding device, and the non-intelligent operation of the TV is realized through gesture control system operation. At the same time, because the full touch control is implemented in this solution, the physical buttons of the device are eliminated, which can better prevent dust from the internal structure of the all-in-one machine, and will not cause mechanical failures that may exist in the physical buttons .

Preferably, it also includes an OPS all-in-one machine, the output port of the OPS all-in-one machine is connected to the display screen, and the control input port of the OPS all-in-one machine is connected to the touch device.

In the actual use of teaching, lectures, etc., the display screen often involves not only the display of TV content, but also the display of computer content. At this time, the display of computer content is realized through the OPS all-in-one machine. The OPS all-in-one machine is equivalent to a host, and the display screen is equivalent to the monitor of the computer. At this time, the combination of the two can realize the functions of the computer, and for the OPS all-in-one machine, it can realize the recognition of touch gestures. The touch device can be connected with the OPS all-in-one machine.

Preferably, the touch device is an electromagnetic induction touch device, an optical touch device, an infrared touch device or a capacitive touch device.

Although the operation of the capacitive touch device is more delicate and precise, the display area of the all-in-one machine is relatively large. For the use environment of the all-in-one machine, the user experience caused by the difference in this level of fineness is almost negligible. , the optical touch device can highlight the cost advantage.

Furthermore, the infrared touch device includes a frame, the frame protrudes from the periphery of the display screen, and a plurality of infrared light sources are arranged on the inner wall of the frame.

Wherein, the infrared light source is uniformly arranged.

Wherein, the distance between two adjacent infrared light sources is 4-8 mm.

Preferably, the distance between two adjacent infrared light sources is 6 mm.

Generally speaking, the smaller the distance between two adjacent infrared light sources, the higher the precision of the touch operation. The specific implementation of infrared touch has been realized in the prior art, and no further description is given here.

The technical principles of the present utility model have been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the utility model, and cannot be construed as limiting the protection scope of the utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific implementations of the present utility model without creative work, and these forms will all fall within the protection scope of the present utility model.
