1. General Description

The LP141WX5 is a Color Active Matrix Liquid Crystal Display with an integral LED backlight 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 14.1 inches diagonally measured active display area with
WXGA resolution (1280 horizontal by 800 vertical 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 LP141WX5 has been designed to apply the interface method that enables low power,
high speed, low EMI. The LP141WX5 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 LP141WX5 characteristics provide an excellent flat display for office automation products
such as Notebook PC.

3. Electrical Specifications

3-1. Electrical Characteristics

The LP141WX5 requires two power inputs. The first logic is employed to power the LCD electronics and to

drive the TFT array and liquid crystal. The second backlight is the input about LED BL with LED Driver.

2. The specified Icc current and power consumption are under

the Vcc = 3.3V , 25ఁ, fv = 60Hz condition and Mosaic pattern.

3. This Spec. is the max load condition for the cable impedance designing.

4. The below figures are the measuring Vcc condition and the Vcc control block LGD used.
The Vcc condition is same as the minimum of T1 at Power on sequence.

9. The operation of LED Driver below minimum dimming ratio may cause flickering or reliability issue.

10. If Jitter of PWM is bigger than maximum, it may induce flickering.

11. This Spec. is not effective at 100% dimming ratio as an exception because it has DC level equivalent

to 0Hz. In spite of acceptable range as defined, the PWM Frequency should be fixed and stable for
more consistent brightness control at any specific level desired.

12.

The life time is determined as the sum of the continuous operation time at which brightness of LCD at the

typical LED current is 50% compare to that of minimum value specified in table 7 under general user condition.
