Product Specification

1. General Description
The LC320EUN is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED)
b ac k l i g ht s ys t em . T he m a t r i x em p l o ys a - S i T h i n F i lm T r an s is t or a s t he a c t i v e e l em en t .
It is a transmissive display type which is operating in the normally black mode. It has a 31.55 inch diagonally
measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel array).
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 8-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 16.7Million colors.
It has been designed to apply the 8-bit 2-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 be 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
24V and VBR (ExtVBR-B : 100%), it is total power consumption.
2. The life time (MTTF) 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.
3. LGD recommend that the PWM freq. is synchronized with One time harmonic of V_sync signal of system.
Though PWM frequency is over 120Hz (max 252Hz), function of LED Driver is not affected.
4. The duration of rush current is about 200ms. This duration is applied to LED on time.
5. Even though inrush current is over the specified value, there is no problem if I2T spec of fuse is satisfied
6. ExtVBR-B signal have to input available duty range and sequence.
After Driver ON signal is applied, ExtVBR-B should be sustained from 5% to 100% more than 500ms.
After that, ExtVBR-B 1% and 100% is possible
For more information, please see 3-6-2. Sequence for LED Driver.

Note: 1. The input of HSYNC & VSYNC signal does not have an effect on normal operation (DE Only Mode).
If you use spread spectrum of EMI, add some additional clock to minimum value for clock margin.

2. The performance of the electro-optical characteristics may be influenced by variance of the vertical
refresh rate and the horizontal frequency

Timing should be set based on clock frequency.

Notes : 1. T1 describes rising time of 0V to 24V and this parameter does not applied at restarting time.
Even though T1 is over the specified value, there is no problem if I2T spec of fuse is satisfied.
2. In T6 section, ExtVBR-B should be sustained from 5% to 100% .

Product Specification
Note : 1. Contrast Ratio(CR) is defined mathematically as :
Surface Luminance with all white pixels
Contrast Ratio =
Surface Luminance with all black pixels
It is measured at 5 point
2. Surface luminance are determined after the unit has been `ON' and 1 Hour after lighting the
backlight in a dark environment at 25 2 C. Surface luminance is the luminance value at n = the
Position number(1, 2, 3, 4, 5) 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 G(N) to G(M) (Rise Time, TrR)
and from G(M) to G(N) (Decay Time, TrD). For additional information see the FIG. 3. (N G to G Spec stands for average value of all measured points.
