Note:
*1. This rating applies to all parts of the module. And should not be exceeded.
*2. The operating temperature only guarantees operation of the circuit. The contrast, response speed,
and the other specification related to electro-optical display quality is determined at the room temperature, T OP =25 ℃
*3. Ambient temperature when the backlight is lit (reference value)
*4. Any Stresses exceeding the Absolute Maximum Ratings may cause substantial damage to the device. Functional operation of this device at
other conditions beyond those listed in the specification is not implied and prolonged exposure to extreme conditions may affect device
reliability.

Cautions:
Exceeding the recommended driving current could cause substantial damage to the backlight and shorten its lifetime.
I F is defined for one channel LED. Optical performance should be evaluated at Ta=25 only If LED is driven by high current, high
ambient temperature & humidity condition. The life time of LED will be reduced. Operating life means brightness goes down to
50% initial brightness. Typical operating life time is estimated data.

Note 1: Definition of optical measurement system.
The optical characteristics should be measured in dark room. After 5 Minutes operation, the optical
properties are measured at the center point of the LCD screen. All input terminals LCD panel must
be ground when measuring the center area of the panel.
Note 2: Definition of viewing angle range and measurement system.
viewing angle is measured at the center point of the LCD by CONOSCOPE(ergo-80)
Note 3: Definition of contrast ratio
“White state “: The state is that the LCD should drive by Vwhite.
“Black state”: The state is that the LCD should drive by Vblack.
Vwhite: To be determined
Vblack: To be determined.

Note 4: Definition of Response time
The response time is defined as the LCD optical switching time interval between “White” state and
“Black” state. Rise time (T ON ) is the time between photo detector output intensity changed from 90%
to 10%. And fall time (T OFF ) is the time between photo detector output intensity changed from 10% to
90%.
Note 5: Definition of color chromaticity (CIE1931)
Color coordinates measured at center point of LCD.
Note 6: Definition of Luminance Uniformity
Active area is divided into 9 measuring areas (Refer Fig. 2). Every measuring point is placed at the
center of each measuring area.
Luminance Uniformity (U) = Lmin/ Lmax
L-------Active area length W----- Active area width
Lmax: The measured Maximum luminance of all measurement position.
Lmin: The measured Minimum luminance of all measurement position.
Note 7: Definition of Luminance:
Measure the luminance of white state at center point.

8. Touch panel Design Precautions
8.1 Mounting Precaution
9.1.1 Bezel Mounting
When mounting the CTP underneath a bezel,the CTP assembly should be mounted using a configuration
that supports the back surface of the TFT module.The bezel edge must be positioned outside the active area
of the CTP.A gap of 0.5mm to 1.0mm is needed between the bezel and the CTP surface.A foam gasket or
similar material should be used to compensate for the tolerance of the enclosure,compression for the
screw,etc.
9.1.2 Flush Mounting
When flush mounting the faceplate with the top of the enclosure,the enclosure must have a ledge for
attaching the overhang of the faceplate as well as a ledge for supporting the back of the TFT module.
9.1.3 Optical Bonding
When flush mounting the faceplate with the top of the enclosure,the enclosure must have a ledge for
attaching the overhang of the faceplate as well as a ledge for supporting the back of the TFT module.
9. Precautions of using LCD Modules
