2. Introduction
LCD MODULE
INT028ATFT / INT028ATFT-TS
Version: 1.0
INT028ATFT
&
INT028ATFT-TS
are integrated display module based upon a TFT display
with 320 x 240RGB resolution. The TFT module is mounted on a PCB on which is mounted
a RAIO RA8872 controller with integrated touch screen control and PWM driving circuit
for the LED backlight. The TFT module is automatically initialised upon power up by an
on-board controller circuit.

Component Life Cycle
1) Storage Life: min. 1 Year
2) Operation Life (*1): min. 43 x 10³ h (24hr/day x 7days/week x 52weeks/year x 5years)
(Not include backlight)
3) Storage and Operation Life Times are defined for a temperature of +25°C
Notes:
*1. Operation life ends when one of the listed faults occurs:
The on/off response-times reach 1.5 times of the max. value specified for a new
display
The contrast is reduced to 0.5 of the original contrast value
Loss of function
The number of cosmetic defects exceeds the maximum defined
