That is to say, the first lateral opening 272 and the second lateral opening 276 are respectively facing two opposite sides of the touch panel 21 instead of facing the substrate 10 , and the first lateral opening 272 has a first orientation, and the second lateral opening has a first orientation. 276 has a second orientation, the first orientation and the second orientation being opposite to each other. For example, assume that the first lateral opening 272 faces the left side of the touch panel 21 and the second lateral opening 276 faces the right side of the touch panel 21 . Thereby, during the assembly process of the touch panel device 1 , the touch module 20 can be placed on the substrate 10 first, and the first balance bar 30 and the second balance bar 40 are respectively moved from opposite sides of the touch module 20 The first lateral opening 272 and the second lateral opening 276 of the assembly plate 25 are inserted, so that the first rotating shaft 31 of the first balance rod 30 and the second rotating shaft 41 of the second balance rod 40 are pivoted to the first long groove respectively. In the groove 271 and the second long groove 275, therefore, the assembly plate 25 does not need to use the above-mentioned top-down pressing method to assemble the first balance bar 30 and the second balance bar 40, so as to achieve convenient, accurate and avoidance of assembly. Advantages of component damage.

In summary, according to the touch panel device according to the embodiment of the present invention, the circuit board of the touch module is accommodated in the receiving groove of the assembly board, so that the overall thickness of the touch module can be reduced to the thickness of the touch panel. The effect of making the device thinner. In addition, the first balance bar and the second balance bar are respectively connected to the first side and the second side of the assembly plate, that is, the assembly plate is not pivotally fixed to one side of the base plate, so that When any part of the touch module (such as all corners or edges of the touch module) is pressed, the first balance bar and the second balance bar can cause the average force of the touch module to decrease and provide good pressing. Feel.
