Note1: I is defined for each channel.

Note2: Optical performance should be evaluated at Ta=25 ℃ only.

Note3: If LED is driven by high current, high ambient temperature & humidity condition,The life time of LED will

Note4: Operating life means brightness goes down to 50% of initial brightness. Typical operating life time is

Table 5.2.2 Thermistor Description

Note1: I F is defined for one channel LEDs. There are a total of 3 LED channels in the backlight unit.

While the LCM is operating, a stable forward current should be supplied. The PWM value is

only for inrush current.

Note3: Optical performance should be evaluated at Ta=25 ℃ only. If the LEDs are driven at high

current or at high ambient temperature & high humidity environment, the lifetime of the LEDs

will be reduced. Operating lifetime means the brightness will decrease to 80% of the original

Note4: An NTC thermistor is included in the LED circuit. Part number: NCP15XH103F0SRC. It is

used for the measuring LED temperature and is located in the LED circuit on the backlight

Note5: To reduce the influence of NTC self-heating and improve the measurement accuracy. suggest

the operating current of NTC be xx mA

Note6: When operating at high temperature, NTC resistance should not be below xx k Ώ

Note1: Definition of optical measurement system.

The optical characteristics should be measured in dark room. After 5 Minutes operation, the optical

characteristics are measured at the center point of the LCD screen.

Note3: Definition of contrast ratio

Note4: Definition of Response time

For TN LCM,t he response time is defined as the LCD optical switching time interval between “White”

state and “Black” state. Rise time (T r ) is the time between photo detector output intensity changed from

90% to 10%. And fall time (T f ) is the time between photo detector output intensity changed from 10% to

For SFT LCM, t he response time is defined as the LCD optical switching time interval between “White” state

and “Black” state. Rise time (T r ) is the time between photo detector output intensity changed from 10% to 90%.

And fall time (T f ) is the time between photo detector output intensity changed from 90% to 10%.

Note5: Definition of color chromaticity (CIE1931)

Color coordinates measured at center point of LCD.

Note 6: Contrast ratio against temperature

CR defines the allowed contrast reduction at the defined temperature based on the CR at room

temperature. For example: CR = (CR@25°C – CR@85°C) / CR@25°C x 100%

Note7: Definition of Luminance Uniformity

Active area is divided into 9 measuring areas (Refer Fig.4). Every measuring point is placed at the

center of each measuring area.

Luminance Uniformity (U) = Lmin/ Lmax

Lmax: The measured Maximum luminance of all measurement position.

Lmin: The measured Minimum luminance of all measurement position.

L-------Active area length; W----- Active area width
