    High Picture Quality 3.4 cm (1.35-Type) 1.05M-dot Wide XGA
    HDTV Projector LCD for the Coming Digital Age
    LCX037BL
    As the trend towards digital TV broadcasting acceler-
    ates, the needs for large screen high picture quality
    displays are growing rapidly. The HDTV LCD projec-
    tor is expected to become one of the mainstays of
    this area.
    To respond to these hopes, Sony has now developed
    a new 3.4 cm (1.35-Type) 720P digital HDTV LCD that
    adopts Sony’s unique high picture quality circuit tech-
    nology and optimal pixel design technology.
    This device, the LCX037BL, is an HDTV front projec-
    tor LCD, a device that will be indispensable for home
    theater displays in the digital age.

    Achieves high transmittance (17%) as a 3.4 cm
    (1.35-Type) 1.05M-dot wide XGA LCD.
    I
    Improved contrast and completely horizontal
    crosstalk-free due to display the adoption of the
    Dot-Line inversion drive method.
    I
    Vertical crosstalk-free up to the HD format due
    to the adoption of the 2STEP dot sequential
    precharge method.
    I
    Brightness shading-free due to the adoption of
    OCS (on-chip spacer) technology.
    I
    Vertical crosstalk-free due to adoption of a high
    light resistance device structure (DMS

    3.4 cm (1.35-Type) LCD
    for 720P Digital HDTV
    Sony has achieved an aperture ratio of
    52% and an optical transmittance of
    17% in a wide XGA display (1366H
    ×
    768V) LCD with 1.05M dots. Achiev-
    ing this required the introduction of a
    unique new Sony-developed structure
    (DMS), the development and introduc-
    tion of a new fabrication process, and
    the use of high-precision LCD orienta-
    tion technology. As a result, this device
    can provide bright fine-grained display
    of digital HDTV broadcasts, and can
    create bright but subtle pictures even on
    a large screen.
    High Picture Quality
    Achieved
    By adopting Sony’s unique newly-
    developed picture quality improving
    “Dot-Line inversion drive method,”
    complete crosstalk-free is achieved.
    (See figure 1.) Due to this drive tech-
    nology and an optimized pixel design
    that reduces the amount of light leak-
    ing around pixels, Sony was able to im-
    prove the contrast to over 350:1 when
    VSIG =
    ±
    5.0 V. Furthermore, to achieve
    vertical crosstalk-free display even for
    video formats such as HDTV that have
    an extremely short blanking period,
    Sony developed the new 2STEP dot se-
    quential precharge drive method. (See
    figure 2.) The LCX037BL achieves high
    uniformity while supporting even higher
    brightness levels by using both the high
    light resistance DMS structure and the
    OCS (on-chip spacer) structure in the
    surface of the device structure. (See fig-
    ure 3.) Additionally, by using the
    CXD3503R color shading correction
    IC, end products can provide fine-
    grained correction not only for the color
    shading due to the LCD panel itself, but
    also that due to the optical system. This
    allows end products to provide excel-
    lent image uniformity.
    Ease of Use
    At the same time, Sony has also devel-
    oped the new CXD3504R as a system
    IC for the LCX037BL, which adopts a
    new drive method. A system structure
    consisting of the CXA3512R high-
    voltage sample-and-hold IC, which has
    an excellent reputation, and the
    CXD2467AQ, which integrates both a
    programmable TG and RGB drivers on
    a single chip, can create an environment
    that can take full advantage of the
    characteristics of this LCD panel. (See
    figure 4.)

    We developed the LCX037BL
    with the goal of achieving the
    superb picture quality required
    to satisfy the home theater
    market. We developed a new
    LCD drive technique, a new device
    structure, and a new system IC
    for this product. All of us in the
    development team strove to
    improve the LCD characteristics
    as much as possible. We are
    confident that the LCX037BL will
    be rated number one in the home
    theater market.
