LC185EXN
Product Specification
1. General Description
The LC185EXN is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
backlight system. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive display type which is operating in the normally black mode. It has a 26.01 inch diagonally
measured active display area with WXGA resolution (768 vertical by 1366 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in Horizontal stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot,
thus presenting a palette of more than 16.7M(6bit + A-FRC) colors.
It has been designed to apply the 8-bit 1-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

2. Temperature and relative humidity range are shown in the figure below.
Wet bulb temperature should be Max 39 C, and no condensation of water.
3. Gravity mura can be guaranteed below 40 C condition.
4. The maximum operating temperatures is based on the test condition that the surface temperature
of display area is less than or equal to 68 C with LCD module alone in a temperature controlled chamber.
Thermal management should be considered in final product design to prevent the surface temperature of
display area from being over 68 . The range of operating temperature may degraded in case of
improper thermal management in final product design.

Notes :
1. Electrical characteristics are determined after the unit has been `ON' and stable for approximately 60
minutes at 25 2 C. The specified current and power consumption are under the typical supply Input voltage
24Vand VBR (ExtVBR-B : 100%), it is total power consumption.
2. Electrical characteristics are determined within 30 minutes at 25 2 C.
The specified currents are under the typical supply Input voltage 24V.
3. The life time is determined as the time which luminance of the LED is 50% compared to that of initial
value at the typical LED current (ExtVBR-B :100%) on condition of continuous operating in LCM state at
25 2 C.
4. LGD recommend that the PWM freq. is synchronized with two time harmonic of Vsync signal of system.
Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected.
5. The duration of rush current is about 10ms.
6. Even though inrush current is over the specified value, there is no problem if I 2T spec of fuse is satisfied.

Product Specification
Notes :1. Contrast Ratio (CR) is defined mathematically as :
Surface Luminance at all white pixels
CR =
Surface Luminance at all black pixels
It is measured at center 1-point.
2. Surface luminance is determined after the unit has been `ON' and 1Hour after lighting the
backlight in a dark environment at 25 2 C. Surface luminance is the luminance value at center
1-point across the LCD surface 50cm from the surface with all pixels displaying white.
For more information see the FIG. 2.
3. The variation in surface luminance , G WHITE is defined as :
G WHITE(5P) = Maximum(Lon1,Lon2, Lon3, Lon4, Lon5) / Minimum(Lon1,Lon2, Lon3, Lon4, Lon5)
Where Lon1 to Lon5 are the luminance with all pixels displaying white at 5 locations .
For more information, see the FIG. 2.
4. Response time is the time required for the display to transit from any gray to white (Rise Time, TrR)
and from any gray to black (Decay time, TrD). For additional information see the FIG. 3.
G to GBW Spec stands for average value of all measured points.
Photo Detector : RD-80S / Field : 2
5. G to G is Variation of Gray to Gray response time composing a picture
Xi = Individual Data
G to G ( ) = (Xi- u)2 u = Data average
N N : The number of Data
6. Viewing angle is the angle at which the contrast ratio is greater than 10. The angles are
determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which
is normal to the LCD module surface. For more information, see the FIG. 4.
7. Gray scale specification
Gamma Value is approximately 2.2. For more information, see the Table 11.
