Absolute maximum rating
Designing of power supply circuit for lamp
Please design the circuit so that high voltage output can be kept for more than 1
second. The shorter time may not start up lamp. The driving inverter circuit is
recommended to be the type w hich lamp current can be controlled.
The type w hich voltage is controlled is not recommended, because it may cause
big current under high temperature and insatiable start-up of lamp under low
temperature.
Heat radiation
Lamp generates heat at lighting and causes temperature rise inside system.
Therefore, designing to radiate heat like radiation slits at cabinet is recommended
to meet the specified operating temperature range for LCD module.
Noise on power line
Spike noise contained in power line causes abnormal operation of driving circuit
and abnormal display. To avoid it, spike noise should be suppressed below VDD
+/- 200mVp-p. (In any case, absolute maximum rating should be kept.)
Power sequence
Before LCD module is switched on, please make sure that power supply and input
signals of system, testing equipment, etc. meet the recommended power
sequence.
Absolute maximum rating specified in this specification has to be kept in any case.
It shows the maximum that cannot be exceeded.
Exceeding it may cause burning or non-recoverable break of electronic
components in circuit. Please make system design so that absolute maximum
rating is not exceeded even if ambient temperature, input signal and components
are varied.
Protection for power supply
Please study to adapt protection for power supply against trouble of LCD module,
depending on usage condition of system. Fuse installed on LCD module should be
never modified. Any modification to make the function of fuse ineffective may
cause burning or break of printed wiring board or other components at circuit
trouble.
Protection against electric shock
High voltage is applied to lamp connector, inverter circuit and lamp at lighting.
Please make design not to expose or be accessible to such high voltage parts to
avoid electric shock.
When LCD module is used under severe condition like outdoor, it is recommended
to use transparent protection cover over display surface to avoid scratches and
invasion of dust and water. In addition, when LCD module is exposed to direct sun
light for long time, use of cut-off filter for ultraviolet rays is also recommended.
Please be careful not to get condensation.
Protection against Static electricity
C-MOS LSI and semiconductors are easily damaged by static discharge. LCD
module should be handled on conductive mat by person grounded w ith w rist strap
etc. to avoid getting static electricity. Please be careful not to generate static
electricity during operation.
