ENH050Q1-320/450/600 Color TFT-LCD Module Features
GENERAL DESCRIPTION
Slim, lightweight and compact
Panelview provides optically enhanced solutions to the
standard Sharp LQ5AW136 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 accepts full color
video signals conforming to the NTSC(M) and PAL(G-B)
system standards.
It can withstand an intense environment, the online
dimension is suitable for an automotive display, compact
size, compatible with 2DIN size.
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.
FEATURES
Dual mode type. [NTSC(M) and PAL(B-G)
standards]
1. Active area/Outline area=70%
2. Thickness: 16.5mm
3. Mass: 185g (Max)
Built-in video interface circuit and control circuit
responsive to two sets of standard RGB analog
video signals.
Reduced refleciton as a resuld of low reflectance
Black-Matrix and Index Matching (IM) film
lamination. IM is available in two surface
treatments, IM/Clear (glossy) and IM/110 (10%
diffusion).
It is possible to use both the simultaneous and the
independent time sampling.
An external clock mode is available.
Optical viewing angle: wide view angle (6 o'clock
direction.) (Customer can use this module as a 12
o'clock viewing direction type by using a display
rotating function to rotate right/left and up/down
scanning direction electrically.)
This module includes a high luminance edge light
that is excellent at low temperature.
It is possible to use the dimming frequency (PWM)
for backlight.
MBK-PAL enables the 234-scanning lines panel to

14. In case of CKC='Lo'. it shows the phase difference from VSY to HSY. In that
case, VSY will be taken at the rise timing of HSY.
15. Adjsuting the optimal voltage on every module at the typical value of power
supply voltage to get the maximum value of contrast. However, in the case that
the power supply voltage is changed, for example the level of power supply
voltage is reduced, adjust it externally to get the best contrast with a resistor you
add to this terminal, or semifixed resistor, VCDC, in module. A recommended circuit
is shown in Fig. 5.
