About drive two 4 digits TM1650 modules

Hi,
I bought two 4 digits TM1650 LED modules,these two modules connected to MCU's I2C interface in parallel.
At first, I thought every module can be set I2C address,so I can set the two with different address,but after I read this chip datasheet,I find every digit have an address, and the TM1650.h seems will set address using beginTransmission method and then write display string.

But how to write string to different modules in parallel?Can I set different addresses for these and how?
thank u.

normally user gives one address to determine devices on I2C bus. positioning for each digit does the lib with
void setPosition(unsigned int aPos, byte aValue);
