In the example of FIG. 3A, if the common voltage VCOM generated by the common voltage adjustment module 140 at step 6 can minimize the flickering degree of the display area 122, the control module 200 will record the corresponding scanning signals VS1-VS4 at this time. Voltage level, for example, the scanning signals VS2 and VS4 are high voltage levels (that is, the switching units M32 and M34 are turned on), and the scanning signals VS1 and VS3 are low voltage levels (that is, the switching units M31 and M33 are turned on) .

Please refer to FIG. 3C . FIG. 3C is a schematic diagram illustrating the operation of the common voltage adjusting module in FIG. 2B to generate a fixed common voltage according to an embodiment of the present invention.

In this way, compared with the prior art, the common voltage adjustment module 140 of this embodiment can generate a corresponding common voltage VCOM by automatically detecting the flickering degree of the display area 122, and fix the value of the common voltage VCOM through the fuse devices 142a-142d, The problem of the resistance value offset of the variable resistor in the prior art can be avoided.

Please refer to FIG. 4A . FIG. 4A is a schematic diagram illustrating a fuse device according to an embodiment of the present invention. As shown in FIG. 4A , the fuse device 400 includes an end portion 402 , an end portion 404 and a middle portion 406 .

For a clearer explanation, FIG. 4C only shows the backup fuse device 420a. As shown in FIG. There is an insulating dielectric layer 440 (for example, a silicon nitride layer) between each end and the second end of the corresponding fusing device 142a. Generally speaking, the fuse device 142a and the backup fuse device 420a are a metal layer. During normal operation, the backup fuse device 420 a and the fuse device 142 a are not in conduction due to the barrier of the insulating medium layer 440 . When the display panel 100 needs to adjust the common voltage VCOM again, the backup fuse devices 420a-420d can be fused by an external laser, and then the backup fuse devices 420a-420d are electrically coupled with a plurality of voltage dividing circuits 144, thereby adjusting the common voltage. The module 140 can readjust the common voltage VCOM again.

In step S560, when the degree of flickering of the display panel is the lowest, the switching of the multiple voltage dividing circuits is stopped, so that the multiple voltage dividing circuits provide a common voltage.

For example, as previously mentioned, as shown in FIG. 2A and FIG. 2C , the light sensor 222 in the detection module 220 can detect the degree of flicker of the display panel 100, and record when the degree of flicker of the display panel 100 is the lowest.

When the flickering degree of is the lowest, the switching unit M3 (such as the aforementioned M31, M33) is turned off. In this way, the corresponding fuse devices 142a, 142c can be blown by the programming current IB.

Then, as shown in FIG. 3C, after the corresponding fuse devices 142a and 142c are blown, the switching unit M1 and the switching units M31-M34 can be turned on, and the switching unit M2 can be turned off, thereby making the multiple voltage dividing circuits 144 fixed.
