    1.1 SCOPE

    This document defines the design and performance

    requirements for an 20/22W inch diagonal , flat panel

    monitor .The display element shall be a WSXGA

    (1680x1050) resolution TFT-LCD (Thin Film Transistor

    Liquid Crystal Display).16.7M color(RGB 6bits+FRC)

    images are displayed on the panel.Video input signals are

    analog RGB (0.7Vp-p). When the systemis powered-on ,

    previously stored screen parameters for a pre-defined

    mode will be recalled if the operating mode is one of stored

    in memory( 19 factory , 9 users timing ).This monitor

    operates normal by non-interlaced mode. DDC (Display

    Data Channel) function is DDC2Bi compliance Power

    saving function complies with the DPMS (Display Power

    Management Signaling) standard.

    1.2 GENERAL REQUIREMENTS1.2.1 Test Condition

    Brightness level & contrast level max. Full white

    pattern test mode following spec. Warm up more than

    1 hr, ambient light < 10 Lux , Luminance meter CA110

    or BM7 or same equipment .

    1.2.2 Test Equipment

    The reference signal source is a calibrated Chroma2135 video generator or higher.The use of other

    signal generators during qualification and production

    is acceptable provided the product complies with this

    specification.

    1.3 ELECTRICAL

    This section describes the electricalrequirement of the

    monitor.The block diagram in Figure1 illustrates the various

    1.3.8 Display Communications Channel

    The monitor assembly shall provide a display

    communications channel that conforms to VESA

    DDC2Bi hardware requirements. This configuration

    shall contain the 128-byte EDID file as specified by

    VESA EDID standard.The monitor should not write to

    the EDID file for the first two minutes of operation

    following power-up UNLESS some action taken by the

    user or the host CPU forces the write (for instance,

    requesting the serial number via the OSD).

    Furthermore, it is recommended that CMOS switches

    be incorporated to isolate the DDC IC from outside

    connections while the EDID Fault Management is

    being updated. This is to prevent corruption of the data

    by attempts to read the data while it is being changed.

    1.3.9 Firmware Update Function (same ISP function)The update firmware need through from the D-Sub

    connector, use DDC I2C bus to do update firmware.

    1.4 PANEL ELECTRICAL

    1.4.1 General Requirements

    The panel used as the display device shall be an

    WSXGA resolution,20/22W, TFT-LCD.This panel shall

    be approved for use in this monitor.

    1.4.2 Panel Timings

    The controller included with the monitor shall translate

    all video timings from the CPU that meet the timing

    requirements listed in Panel specification into timings

    appropriate for the panel. Under no circumstances may

    the controller supply the panel with timings that may

    result in damage. The controller shall insulate the

    panel from the CPU , so that the panel shall always be

    driven per it's own specification regardless of the

    timings being sent from the CPU.

    1.4.3 Polarizer Hardness

    The outer face of the front polarizer panel shall be

    1.4.5.5 Defect Terminology

    Table 3 gives the descriptive terms used in classifyin

    defects.

    1.4.5.6 Smudges, Streaks and Smears

    When viewing the panel oriented so as to maximize

    reflected light , there shall be no visible smudging ,

    streaking, smearing or other nonuniformity fromcontaminants ,fingerprints,or defects in any of the vi

    surfaces. This is independent of whether the unit is

    operating or off .

    1.4.5.7 Other Defects

    Undefined defects that are considered to be rejectab

    by LiteOn will be reviewed by Lite-On as they beco

    apparent. These panels will be referred to the Lite - Corporate / Manufacturer Purchasing Agreement fo
