Product Specification

1. General Description

The LC260WX2 is a Color Active Matrix Liquid Crystal Display with an integral External Electrode
Fluorescent Lamp(EEFL) backligh t system. The matrix employs a-Si Thin Film Transistor as the active
element. It is a transmissive type display operating in the normally black mode . This TFT-LCD has a 26.0
inch diagonally measured active display area with WX GA 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 vertical
stripes. Gray scale or the luminance of the sub-pixel color i s determined with a 8-bit gray scale signal for
each dot, thus, presenting a palette of more than 16.7M(True) colors. The LC260WX2 has been designed to
apply the LVDS interface. It is intended to support LCD TV, PC TV where high brightness, super wide
viewing angle, high color gamut, high color depth, and fast response time are important.

Notes :

1. Electrical characteristics are determined after the unit has been ‘ON’ and stable for approximately 120
minutes at 25±2°C. The specified current and power consumption are under the typical supply Input voltage
24Vand V

The ripple voltage of the power supply input voltage is under 0.5 Vp-p. LGD recommend Input Voltage is

24.0V ± 5%.

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 brightness of the lamp after lighted for 5minutes is defined as 100%.
TS is the time required for the brightness of the center of the lamp to be not less than 95% at typical current.

The screen of LCD module may be partially dark by the time the brightness of lamp is stable after turn on.

4. Specified Values are for a single lamp which is aligned horizontally.
The life time is determined as the time which luminance of the lamp is 50% compared to that of initial value
at the typical lamp current (V

5. LGD recommend that the PWM freq. is synchronized with One or Two times harmo nic of Vsy ncsignal of system.

Notes :

1. All GND(ground) pins should be connected together to the LCD module’s metal frame.

2. All VLCD(power input) pins should be connected together.

3. All Input levels of LVDS signals are based on the EIA 644 Standard.

4. Specific pins(pin No. #10, #27~#28) are used for DCR function of the LCD module.
If not used, these pins are no connection.

5. Specific pin No. #30 is used for “No signal detection” of system signal interface.
It should be GND for NSB(No Signal Black) during the system interface signal is not.
If this pin is “H”, LCD Module displays AGP(Auto Generation Pattern).

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.
