[0019] The first driving layer 31A is disposed on the upper surface S1. The first driving layer 31A faces one side of the upper surface S1 and is connected to one side of the first conductive hole 32A. The first conductive hole 32A extends from the upper surface S1 to the lower surface S2 and penetrates the substrate 10 to connect the driving circuit 20, that is, the other side of the first conductive hole 32A is connected to the driving circuit 20.

The first conductive hole 32A obtains the corresponding driving signal from the driving circuit 20 and transmits the corresponding driving signal to the first driving layer 31A. In other words, the first conductive hole 32A serves as an auxiliary element for transmitting the driving signal between the first driving layer 31A and the driving circuit 20, and the first driving layer 31A obtains the corresponding driving signal through the first conductive hole 32A. The first insulating layer 40 is disposed on the first driving layer 31A, covers the first driving layer 31A to protect the first driving layer 31A, and separates the first driving layer 31A from the second driving layer 31B. The first insulating layer 40 is formed in the form of thermosetting adhesive or thermal lamination.

In other words, the second driving layer 31B partially overlaps with the second conductive hole 32B, and the second conductive hole 32B partially overlaps with the driving circuit 20. The opposite sides of the second conductive hole 32B connect the second driving layer 31B and the driving circuit 20. The depth of the second conductive hole 32B is greater than the depth of the first conductive hole 32A. The second driving layer 31B is connected to the driving circuit 20 through the second conductive hole 32B. The second conductive hole 32B obtains the corresponding driving signal from the driving circuit 20 and transmits the corresponding driving signal to the second driving layer 31B.

The second insulating layer 50 is disposed on the second driving layer 31B and covers the second driving layer 31B to protect the second driving layer 31B. In other words, the second insulating layer 50 serves as a protective layer for the second driving layer 31B. The material of the second insulating layer 50 can be a resin material.

[0021] In the driving device of the present embodiment, multiple different driving signals from the driving circuit are received by setting up multiple driving modules. In addition, multiple driving layers of the multiple driving modules are protected by setting up multiple insulating layers corresponding to the multiple driving modules. The multiple driving modules (30A, 30B) are placed on the upper surface S1, and each driving module (30A, 30B) includes a corresponding driving layer (31A, 31B) and a conductive hole (32A, 32B). The driving layer (31A, 31B) is connected to the driving circuit 20 through the conductive hole (32A, 32B), and the two driving layers (31A, 31B) of two adjacent driving modules (30A, 30B) overlap in the projection part on the substrate 10. Specifically, the multiple driving modules are set independently of each other, and the multiple positions of the multiple driving modules are different from each other. The driving layer of each driving module receives the driving signal through the corresponding conductive hole, and the driving signals received by the multiple driving layers of the multiple driving modules are different from each other, and the multiple receiving signal time points of the multiple driving signals received by the multiple driving layers are different from each other. In other words, the driving of the multiple driving modules is independent of each other and is segmented, and the operating frequencies corresponding to the multiple driving layers of the multiple driving modules are different from each other.

[0022] Further, the driving layer of each driving module group is a driving circuit, and the conductive holes of each driving module group are through holes containing metal materials, and the metal materials may include copper, tin and lead, for example. The driving layer of each driving module group is connected to one side of the corresponding conductive hole, and the other side of the conductive hole is connected to the driving circuit 20. The conductive holes of each driving module group receive the corresponding driving signals from the driving circuit 20 and transmit the corresponding driving signals to the corresponding driving layer. The driving layer of each driving module group is actuated according to the corresponding driving signals.
