Specifications

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. Operating voltages required
are provided by a DC/DC converter.
Unless otherwise specified, performance characteristics are guaranteed when
measured at 25°C.

Power

The supply voltages required for the displays are shown in Table 1. All internal
high voltages are generated from display supply voltage (V H ). The logic supply
voltage (V L ) should be present whenever video input signals or V H is applied.

CAUTION: Absolute maximum ratings are those values beyond which
damage to the device may occur.

Description
Video logic high voltage
Video logic low voltage
Video logic input current
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.
