Specifications
Performance characteristics are guaranteed when measured at 25°C with rated
input voltage unless otherwise specified. The minimum and maximum
specifications in this manual should be met, without exception, to ensure the
long-term reliability of the display. Planar does not recommend operation of
the display outside these specifications.
Control Basics
The EL 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.
Power
The supply voltages are shown in Table 1. All internal high voltages are
generated from the display supply voltage (V H ).
