LP101WSB
Liquid Crystal Display
Product Specification
1. General Description
The LP101WSVGA 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 10.1inches diagonally measured active display
area with WSVGA resolution(1024 horizontal by 600 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 LP101WSB has been designed to apply the interface method that enables low power, high speed, low
EMI.
The LP101WSB 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
LP101WSB characteristics provide an excellent flat display for office automation products such as Notebook
PC.

3-1. Electrical Characteristics
The LP101WSB 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.

1. The measuring position is the connector of LCM and the test conditions are under 25℃, fv = 60Hz,
Mosaic pattern.
2. The specified Icc current and power consumption are under
the Vcc = 3.3V , 25℃, fv = 60Hz condition whereas Mosaic pattern
is displayed and fv is the frame frequency.
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 the minimum of T1 at Power on sequence.

5. This impedance value is needed to proper display and measured form LVDS Tx to the mating connector.
6. The measuring position is the connector of LCM and the test conditions are under 25℃.
7. The current and power consumption with LED Driver are under the Vled = 12.0V , 25℃, Dimming of
Max luminance whereas White pattern is displayed and fv is the frame frequency.
8. The below figures are the measuring Vled condition
and the Vled control block LGD used.

9. The operation of LED Driver below 10% dimming ratio may cause flickering or reliability issue.
10. If Jitter of PWM is bigger than maximum. It may cause 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 time at which the typical brightness of LCD is 50% compare to that of
initial value at the typical LED current. These LED backlight has 2 strings on it and the typical current
of LED‟s string is base on 22mA.
