Specifications
Performance characteristics are guaranteed when measured at 25°C with rated
input voltage unless otherwise specified.
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. Required operating voltages
are provided by an integrated DC/DC converter.
Power
The supply voltages required for the displays are shown in Table 1. All internal
high voltages are generated from display supply voltage (V
voltage (V
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.

There is no overcurrent protection on either the V H or V L inputs to protect
against catastrophic faults. Planar recommends the use of a series fuse on the 12
volt supply. A general guideline is to rate the fuse at 1.8 to 2 times the display
maximum current rating.
