ENH064V1-800 Color TFT-LCD Module Features
GENERAL DESCRIPTION
WEDC provides optically enhanced solutions to the
standard Sharp LQ64D343 color active matrix LCD
module. The ENH064V1-800 enhancement is an index
matching (IM) film lamination to the front surface of the
display polarizer. The IM film is available in two surface
treatments - IM/Clear and IM/110 (a 10% diffusion). The
second enhancement is the incorporation of an enhanced
light guide (ELG) providing for up to 30% increase in
brightness.
This module is composed of a color TFT-LCD panel, driver
ICs, control circuit and power supply circuit and a backlight
unit. Graphics and texts can be displayed on a 640 x
RGB x 480 dot panel with 262,144 colors by supplying
18-bit data signal (6-bit/color), four timing signals, +5V
DC supply voltage for TFT-LCD panel driving and supply
voltage for backlight.
The TFT-LCD panel used for this module is a low-reflection
and higher-color-saturation type. Therefore, this module is
also suitable for multimedia use. Viewing angle is 6 o’clock
direction. This module offers a wide viewing angle and high
brightness (800cd/m2). Backlight-driving DC/AC inverter is
not built in this module.
WEDC assumes no responsibility for any damage
resulting from the use of the device which does not
comply with the instructions and the precautions specified
in these specification sheets. WEDC does assume the
responsibility for the warranty of the enhanced product.

BACKLIGHT DRIVING
The backlight system is an edge-lighting type with
four CCFTs (Cold Cathode Fluorescent Tube).
The Characteristics of a single lamp are shown in the

Notes:
1) Lamp current is measured with current meter for high frequency as shown below.
Module
1
3 ~A
Inverter
3 pin is VLOW
2) At the condition of YL=(300) cd/m2
3) Lamp frequency may produce interference with horizontal synchronous frequency,
and this may cause horizontal beat on the display. Therefore, lamp frequency shall
be detached as much as possible from the horizontal synchronous frequency and
from the harmonics of horizontal synchronous to avoid interference.
4) The open output voltage of the inverter shall be maintained for more than 1 sec;
otherwise the lamp may not be turned on.
5) Since lamp is consumable, the life time written above is referential value and is not
guaranteed in this specification sheet by WEDC.
Lamp life time is defined that it applied either (1) or (2) under this condition
(Continuous turning on at Ta=25°C, IL=6mArms)
1) Brightness becomes 50% of the original value under standard condition.
2) Kickoff voltage at Ta=0°C exceeds maximum value, 1000 Vrms. If operating under
lower temp environment, the lamp exhaustion is accelerated and the brightness
becomes lower.
(Continuous operating for around 1 month under lower temp condition may reduce
the brightness to half of the original brightness.)
In case of such usage under lower temp environment, periodic lamp exchange by
WEDC is recommended.
Note:
1) The performance of the backlight, for example life time or brightness, is influenced by
the characteristics of the DC /AC inverter for the lamp. When designing or ordering
the inverter, make certain that poor lighting caused by the mismatch of the backlight
and the inverter (mis-lighting, flicker, etc.) do not occur. Once this is confirmed, the
module should be operated in the same condition as it is installed in the instrument.
