LC260EXN
Product Specification
1. General Description
The LC260EXN 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(true) colors.
It has been designed to apply the 8-bit 1-port LVDS interface.
It is intended to support LCD TV, PCTV where high b
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.

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
(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(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.
4. LGD recommend that the PWM freq. is synchronized with One 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
T spec of fuse is satisfied.

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
3. Timing should be set based on clock frequency.
