Temperature Coefficient

As the viscosity, and therefore the contrast, of the LCD are subject to change with temperature, there's the need

to vary the LCD Voltage with temperature. The STE2002 provides the possibility to change the VLCD in a linear

fashion against temperature with eight different Temperature Coefficient selectable through the T2, T1 and T0

bits. Only four of them are available with basic instruction set (TC1 & TC0 Bits).

Figure 5.

Finally, the VLCD voltage at a given (T) temperature can be calculated as:

VLCD(T) = VLCDo · [1 + (T-To) · TC]
