For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0032] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a low-cost, small-sized IC, a display module and a smart watch.

[0033] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0034] First, reference Figure 2, a low-cost and small-size IC, characterized by comprising: a first metal wiring layer 100, an insulating layer 200 and a second metal wiring layer 300 stacked in sequence;

[0037] When the voltage connection terminal 110 is charged, the charges are stored between the first metal wiring layer 100 and the second metal wiring layer 300 to form a voltage terminal capacitor.

[0038] According to the characteristics of the capacitor itself, the capacitor is composed of structural features such as electrode layers at both ends and an insulating layer in the middle. Generally speaking, charges will move under force in an electric field. When there is a medium between conductors, the movement of charges is hindered and the charges are accumulated on the conductors, resulting in the accumulation and storage of charges, and the amount of stored charge is the capacitance. Therefore, in the utility model, when the voltage connection end is charged, the charge is accumulated and stored between the first metal wiring layer and the second metal wiring layer to form a voltage end capacitor, which can replace the chip capacitor set in the peripheral circuit in the prior art, so that the capacitors of each voltage end are formed inside the IC, thereby eliminating the capacitor components outside the IC, eliminating the cost of capacitor components and SMT processing costs, and further streamlining the structure, making the IC, display module and smart watch products thinner and improving market competitiveness.

During use, the voltage terminal capacitor can be charged by charging the voltage connection terminal.
