1. General Description

The LP141XA-C1FJ is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) back light system. The matrix employs a-Si Thin Film Transistor as the active element. It is a
transmissive type display operating in the normally white mode. This TFT-LCD has a 13.3 inch diagonally
measured active display area with XGA resolution(768 vertical by 1024 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
brightness of the sub-pixel color is determined with a 6-bit gray scale signal for each dot, thus, presenting a
palette of more than 262,144 colors.
The LP141XA-C1FJ has been designed to apply the interface method that enables low power, high speed
low EMI. Flat Link must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LP141XA-C1FJ is intended to support applications where thin thickness, low power are critical factors
and graphic displays are important. In combination with the vertical arrangement of the sub-pixels, the
LP141XA-C1FJ characteristics provide an excellent flat panel display for office automation products such as
Notebook PC.

3. Electrical Specifications
3-1. Electrical Characteristics

The LP141XA-C1FJ requires two power inputs. One is employed to power the LCD electronics and to drive
the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an
inverter. The inverter is an external unit to the LCD.

Notes: 1. The specified current and power consumption are under the Vcc = 3.3V , 25℃, fv = 60Hz condition
whereas Black pattern is displayed.

2. This impedance value is needed to proper display and measured form LVDS Tx to the mating
connector.

www.jxlcd.com

3. The duration of rush current is about 20ms.

4. The variance of the voltage is ±10%.

5. The transformer output voltage in the inverter must be high considering to the loss of the ballast
capacitor in the inverter.

6. The lamp power consumption shown above does not include loss of external inverter.

7. The life time is determined as the time at which brightness of lamp is 50% compare to that of initial
value at the typical lamp current
