Pixelworks ICs are used in this projector
The three 0.7-inch polysilicon thin-film transistor LCD panels of the 
PLV-ZE1 display 964 x 544-pixel images (a total of 1,573,248 pixels) in 
true 16:9 format.Lens shift lets you precisely adjust the 
projection screen position (full-screen 
shift up and down, 1/2-screen shift left 
and right). The projected image stays 
undistorted and there is no quality 
degradation.
Vertical keystone correction with a correction range of +/- 20 degrees 
compensates for trapezoidal image distortion.
The remote control function keys light up for easy use in dark rooms.
The 1.3x zoom/focus optimizes viewing conditions.
The sleek, minimalist design suits any room decor, and a drop-down 
panel protects the lens when not in use.
The short-throw zoom lens projects images onto a 100-inch screen 
from as close as about ten feet.
A new compact, low-noise fan keeps noise down to a quiet 23 dBA.
The PLV-Z1X has component, S-Video, composite, and Serviceport (RS-232C) 
terminals.
Wide LCD Panel with High 1.55-Million Pixel Resolution 
The PLV-Z1Xs advanced 
optical system delivers a high 
1000:1 contrast ratio for 
sharp images with stunningly 
real blacks.
This system divides the lamp light into the three primary colors (red, 
green and blue) and projects them separately onto the screen to 
eliminate color mixing. It projects high-quality images with faithful color 
reproduction from DVD and other sources.
The 3D Automatic Uniformity Correction Control (AUCC) circuit 
ensures uniform projection, balancing uneven color and brightness 
gradations for more natural images.
This function adjusts contrast in line with the input signal, improving gradation 
for sharper images.
The gamma correction mode has Standard, Cinema, Real (for 
graphics), and four user settings to select from.

1. Precautions and Safety Notices 
1. Appropriate  Operation   
(1)  Turn off the product before cleaning.   
(2)  Use only a dry soft cloth when cleaning the LCD panel surface.   
(3)  Use a soft cloth soaked with mild detergent to clean the display housing.   
(4)  Use only a high quality, safety approved AC/DC power cord.   
(5) Disconnect the power plug from the AC outlet if the product will not be used for a long period of time.   
(6) If smoke, abnormal noise, or strange odor is present, immediately switch the LCD display off.   
(7) Do not touch the LCD panel surf ace with sharp or hard objects.   
(8) Do not place heavy objects on the LCD di splay, video cable, or power cord.   
(9) Do not use abrasive cleaners, waxe s or solvents for your cleaning.   
(10) Do not operate the product under the following conditions:    -  Extremely hot, cold or humid environment.   
-   Areas containing excessive dust and dirt.   
-   Near any appliance generating a strong magnetic field.   
-   In direct sunlight.   
2. Caution   
  No modification of any circuit should be attempted. Servi ce work should only be performed after you are thoroughly 
familiar with all of the following safety checks and servicing guidelines.   
3. Safety Check   
  Care should be taken while servicing this LCD display. Because of the high voltage used in the inverter circuit, the voltage i s 
exposed in such areas as the a ssociated transformer circuits.   
4. LCD Module Handling Precautions   
4.1 Handling Precautions   
(1) Since front polarizer is easily damaged, pay attention not to scratch it.   
(2)  Be sure to turn off power supply when connecting or disconnecting input connector.   
(3)  Wipe off water drops immediately. Long contact with water may cause discoloration or spots.   
(4)  When the panel surface is soiled, wipe it with  absorbent cotton or other soft cloth.   
(5)  Since the panel is made of glass, it may break or  crack if dropped or bumped on hard surface.   
(6)  Since CMOS LSI is used in this module, take care of static electricity and ensure human earth when handling.   
(7)  Do not open or modify the Module Assembly.   
(8)  Do not press the reflector sheet at the back of the module in any direction.   
(9)  In the event that a Module must be put back into the packing container slot after it was taken out of the    container, do 
not press the center of the CCFL Reflector edge. Instead, pr ess at the far ends of the CFL Reflector edge softly. 
Otherwise the TFT Module may be damaged.   
(10)  At the insertion or removal of the Signal Interface Connector , be sure not to rotate or tilt the Interface Connector of 
the TFT Module.   
(11)  After installation of the TFT Module into an enclosure (LCD  monitor housing, for example), do not twist or bend the 
TFT Module even momentarily. When designing the enclosure, it should be taken into consideration that no 
bending/twisting forces may be applied to the TFT Mo dule from outside. Otherwise the TFT Module may be 
damaged.  
(12)  The cold cathode fluorescent lamp in the LCD contains a small amount of mercury. Please follow local ordinances or 
regulations for disposal.   
(13)  The LCD module contains a small amount  of materials having no flammability grade. The LCD module should be 
supplied with power that complies with the requirements  of Limited Power Source (IEC60950 or UL1950), or an 
exemption should be applied for.   
(14) The LCD module is designed so that the CCFL in it is supplied by a Limited Current Circuit (IEC60950 or 
UL1950). Do not connect the CCFL to a Hazardous Voltage Circuit

Correct methods :  Incorrect Methods : 
Only touch the metal-frame of the panel or the front 
cover of the monitor. 
Do not touch the surface of the polarizer .  Surface of the panel is pressed by fingers & this may 
cause “ MURA “ 
  
  Take out the monitor with cushion  Take out the monitor by grasping the LCD panel.  That may cause “ MURA“. 
  
Place the monitor on a clean & soft foam pad .  Place the monitor on foreign objects . 
That could scratch the surface of panel
