LP133WH2
Liquid Crystal Display
The LP33WH2 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 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.
2. This impedance value is needed to proper display and measured form
LVDS Tx to the mating connector.
3. The specified LED current and power consumption are under the Vled = 12.0V , 25• , Dimming of Max
luminance whereas White pattern is displayed and fv is the frame frequency.
4. The operation of LED Driver below minimum dimming ratio may cause flikering or relaibility issue.
5. 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.
6. The life time is determined as the time at which brightness of LCD is 50% compare to that of minimum
value at Table 7. These LED backlight has 6 strings on it and the typical current of LED’s
string is base on Table 2.
