Specifications
The TFEL panel is a matrix structure with column and row electrodes arranged in an X-Y
formation. Light is emitted when an AC voltage of sufficient amplitude is applied at a row-
column intersection. The display operation is based on the symmetric, line-at-a-time data
addressing scheme.
3.1
Power
The supply voltages are shown in Table 1. All internal high voltages are generated from the
display supply voltage (V
H
). The logic supply voltage (V
L
) should be present whenever video
input signals are applied. The minimum and maximum specifications in this manual should be
met, without exception, to ensure the long-term reliability of the display. Performance
characteristics are guaranteed when measured at 25
C with rated input voltage unless
otherwise specified. Beneq does not recommend operation of the display outside these
specifications.
