ENH064V1-300/450 Color TFT-LCD Module Features
GENERAL DESCRIPTION
WEDC provides optically enhanced solutions to the
standard Sharp LQ64D343 color active matrix LCD
module. The first 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, power supply circuit and a backlight
unit. Graphics and text can be displayed on a 640 X 3
X 480 dot panel with 262, 144 color by supplying 18-bit
data signal (6bit/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 is the type of wide viewing angle and high
brightness (350cd/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.
