[0041] Please refer to Figure 2A 、 Figure 2B 、 Figure 2C 、 Figure 2D 、 Figure 2E and Figure 2F In the present invention, in order to achieve the aforementioned purpose of improving printing performance in the present invention, the inkjet chip circuit structure 300 proposed by the present invention is used to control an inkjet chip structure 200. Among them, the plurality of nozzle holes 210 form a nozzle hole double-row parallel structure as shown in Figure 2A 、 Figure 2B on the surface of the inkjet chip structure 200 (this nozzle hole double-row parallel structure is on the same Y-axis and can be used for the same printing point to be printed twice by the left and right row nozzle holes 210, making the printing color bright and full), such as Figure 2C 、 Figure 2DThe double-row staggered structure of the nozzle holes shown in FIG. 1 (the double-row staggered structure of the nozzle holes can make the printing color bright and full), or Figure 2E , Figure 2F The single-row structure of the nozzles shown; wherein in the double-row parallel structure of the nozzles, the vertical distance between two longitudinally adjacent nozzles 210 in a single row is 80μm-90μm, and in the double-row staggered structure, the vertical distance between two laterally staggered adjacent nozzles 210 is 40μm-45μm, and in the single-row structure of the nozzles, the vertical distance between any two longitudinally adjacent nozzles 210 in the single row is 40μm-45μm. In addition, in the above-mentioned embodiments, the width of the ink supply hole 200A is more than 80μm.

[0042] In order to effectively control the above-mentioned inkjet wafer structure 200, please refer to Figure 3 and Figure 4 The present invention proposes a novel inkjet chip circuit structure 300, which includes: a plurality of control modules 310, thereby controlling inkjet printing, and the plurality of control modules 310 further have: a first power supply unit 311; a first power control unit 313, coupled to the first power supply unit 311, and controlling the opening and closing of the first power control unit 313 by the first power supply unit 311; an addressing unit 315, coupled to the first power control unit 313, and supplying the first power control unit 313 with power required for operation by transmitting an addressing signal; a second power control unit 317, coupled to the first power control unit 313, and controlling the opening and closing of the second power control unit 317 by the first power supply unit 311 and the addressing signal from the addressing unit 315; a second power supply unit 316, coupled to the second power control unit 317; The control unit 316 supplies the power required by the second power control unit 317; the third power supply unit 319 is coupled to the first power control unit 313; the third power control unit 320 is coupled to the third power supply unit 319 and the first power control unit 313, so that the third power supply unit 319 and the first power control unit 313 control the opening and closing of the third power control unit 320; and the heating unit 312 is coupled to the second power supply unit 316 to heat the ink required for inkjet printing; wherein, when the first power control unit 313 and the second power control unit 317 are both turned on and the third power control unit 320 is turned off, the heating unit 312 starts to heat the ink required for inkjet printing, and the printing range of the inkjet chip circuit structure control 300 is between 23900μm-27000μm.

[0043] According to an embodiment of the present invention, the operating mechanism of the above-disclosed inkjet wafer circuit structure 300 is as follows. When an addressing signal is input through the addressing unit 315 and the power input through the first power supply unit is a relatively high voltage, the first power control unit 313 will conduct. And if the power input through the second power supply unit 316 also provides a high voltage at this time, the second power control unit 317 will also be in a conducting state. At the same time, if the power from the third power supply unit 319 is a low voltage, the third power control unit 320 will be turned off. At this time, when the first power control unit 315 and the second power control unit 317 are turned on and the third power control unit 320 is turned off, the heating unit 312 will obtain the energy to heat the ink and the inkjet printing signal, and start to heat the ink, causing the ink to generate bubbles and be extruded to eject the ink from the nozzle 210. On the contrary, when the first power supply unit 311 provides a low voltage, the second power supply unit 316 provides a low voltage, and the third power supply unit 319 is a high voltage, the addressing signal will not be transmitted to the second power control unit 317 through the first power control unit 313, and the heating unit 312 will not start to heat the ink, thereby achieving the purpose of controlling inkjet printing of the inkjet wafer circuit structure 300.

[0044] Please refer to Figure 4 , according to an embodiment of the present invention, the plurality of control modules 310 can form an array with two rows S1 and S2 in the inkjet wafer circuit structure 300, corresponding to more than 600 nozzles 210 included in the inkjet wafer structure 200. This array is beneficial to the wiring layout that matches the arrangement space of the nozzles 210 on the inkjet wafer structure 200, so as to effectively improve the printing quality. In the embodiment of the present invention, S1 and S2 can respectively correspond to Figure 2A , Figure 2B the double-row side-by-side structure of the nozzles shown, thereby respectively controlling the nozzles 210 in the left and right rows, such as Figure 2C , Figure 2D the double-row staggered structure of the nozzles shown, thereby respectively controlling the nozzles 210 in the left and right rows, or such as Figure 2E , Figure 2FThe shown nozzle single-row structure is used to separately control the odd-numbered nozzles 210 (the 1st, 3rd, 5th,...) from top to bottom and the even-numbered nozzles 210 (the 2nd, 4th, 6th,...) from top to bottom. It should be noted that the left and right two rows or the odd and even nozzles 210 corresponding to the above S1 and S2 are only examples and are not used to limit the aspects of the present invention. Those skilled in the art can adjust the nozzles 210 corresponding to S1 and S2 or the arrangement aspect of the control module 310 in the inkjet chip circuit structure 300 according to the above description and the application requirements after reading the specification of the present invention, which is hereby described. According to an aspect of the present invention, in the arrays of the two rows of S1 and S2, corresponding first power supply units 311 will provide the corresponding power, so that the single and double control of the two rows of nozzles 210 such as the above left and right double-row parallel structure and double-row staggered structure, and the single row of nozzles 120 in the nozzle single-row structure can be completed. The description here is only an example, and those skilled in the art can adjust the structure of the present invention according to the manufacturing or application requirements to meet the needs of the actual industry.

[0045] According to the content of the present invention, the inkjet chip circuit structure 300 further includes a first grounding unit 314 and a second grounding unit 318, which are respectively coupled to the third power supply control unit 320 and the second power supply control unit 317 to provide power protection for grounding the inkjet chip circuit structure 300.

[0048] In summary, the main purpose of the present invention is to provide an inkjet chip circuit structure to control the corresponding inkjet chip structure. By optimizing the wiring of the inkjet chip circuit structure and cooperating with the spatial arrangement layout of the nozzles on the inkjet chip structure, the overall performance such as the printing color, resolution, printing range, and printing speed is further improved to meet the increasingly stringent requirements of the market and meet the needs of industrial utilization.
