Duty cycle
This parameter is also known as Duty number or COM number. Because
STN/TN LCD is usually driven by time-division dynamic scanning
mode, in this mode, the ratio of the effective turn-on time of each
COM to the whole scan cycle, i.e. Duty, is fixed, equal to 1/COM
number. Bias: Bias
The driving waveform of SEG/COM of LCD is analog signal, and the
ratio of analog voltage to the maximum output voltage of LCD is
called bias. Generally speaking, Bias is expressed by the ratio of
the lowest output voltage to the highest output voltage. Generally
speaking, there is a certain relationship between Bias and Duty.
The more the number of Duty, the shorter the scanning time of each
COM. To achieve the same display brightness and contrast, the
voltage of VON will be increased, and the difference between the
selection level and the non-selection level needs to be increased,
that is, Bias needs to be increased. There is an empirical formula
between Duty and Bias, that is, to achieve the same display
brightness and contrast.
