AI Technical Summary

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

[0004] In the prior art, the signal channel of the driver chip can be reduced by setting the driving electrodes and the control circuit arranged in an array. At this time, the driver chip is an active driver chip, but the driving voltage and output of the active driver 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 about 50V. However, according to the driving voltage of the active driver chip in the prior art, the high-voltage driver chip can generally only provide about 30V. Voltage, so the existing active driver chip has the problem of insufficient driving voltage
