Ic Card - Mitsubishi Electric MELDAS C6 Instruction Manual

(2) Other precautions for use
(a) Backlight life
The life of the backlight is 25,000 hours/25°C. (Time for luminance to drop to 50% of the initial
value.)
The backlight life is dependent on the temperature. The life tends to be shorter when used
continuously at lower temperatures.
(b) Luminance start
Due to the characteristics of the backlight, the luminance could drop slightly at lower temperatures. It
will take approx.10 to 15 minutes for the luminance to reach the rated value after the power is turned
ON.
(c) Unevenness, luminescent spots and irregularities
Uneven brightness, small luminescent spots or small dark spots may appear on LCD, but this is
not a fault.
(d) Contrast
The contrast of STN method LCD panels changes with temperature fluctuation. If this happens
and the panel is difficult to see, open the operation box door and adjust the contrast with the
contrast adjustment potentiometer on the LCD signal interface PCB.
When using the 10.4 LCD, the brightness can be adjusted with the parameter settings.
