Model for Luminance and Power Dissipation
where the symbols represent:
f = the Light Pulse Frequency
Ci = the Insulator Capacitance
Vmod = the Voltage above the External Threshold Voltage
Vdth = the Internal Diode Threshold Voltage
For a typical commercial TFEL display the values of these parameters are as follows:
Substituting these values into Equation 1 gives the result:
L = h * P = 2* h *f*Ci*Vmod*Vdth
Substituting these values into TFEL Luminance vs. Power Expression gives the result:
