Problems solved by technology

The control circuit usually uses a passive drive chip, but due to the limited drive capability of the passive drive chip, when it is desired to perform a large number of chemical micro-reactions or substance detection at the same time, it is necessary to set a lot of drive electrodes
In order to provide signals for many driving electrodes, the driver chip needs to have many signal channels (pins / pins), but the current passive driver chip cannot support
[0005] In the prior art, the signal channels of the drive chip can be reduced by setting the drive electrodes and control circuits arranged in an array. At this time, the drive chip is an active drive chip, but the drive voltage and the output of the active drive chip in the prior art The voltage that can drive the droplet movement varies greatly. Generally, the voltage that can drive the droplet movement needs to be around 50V. However, according to the driving voltage of the active drive chip in the prior art, the high-voltage drive chip can generally only provide a drive of about 30V. Voltage, so the existing active driver chip has the problem of insufficient driving voltage
