ENH057Q1-350/450/600 Color TFT-LCD Module Features
GENERAL DESCRIPTION
Panelview provides optically enhanced solutions to the
standard Sharp LQ057Q3DC02 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 a reflective polarizer (RP) to improve
brightness by up to 40%. The third enhancement is
the addition of prism films (RPp) further increasing the
brightness of the display. The 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 320 X 3 X 240 dot panel with 262,
144 color by supplying 18 bit data signal (6bit/color), four
timing signals.
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 12
o'clock direction. This module is the type of wide viewing
angle and high brightness 350cd/m2. It has horizontal
display mode and vertical display mode.
Backlight-driving DC/AC inverter is not built in this
module.
Panelview 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. Panelview does assume the
responsibility for the warranty of the enhanced product.

6. 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. In case of such usage under
lower temperature environments, periodic lamp exchange by Panelview is recommended.
