ENH084V1-300/400 Color TFT-LCD Module Features
GENERAL DESCRIPTION
Panelview provides optically enhanced solutions to the
standard Sharp LQ084V1DG21 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, +3.3V/+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. Optimum viewing
direction is 12 o'clock.
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.
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.

Notes:
1. Lamp current is measured with current meter for high frequency as shown above.
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 consumables, the life time written above is referential value and it is not guaranteed in this specification sheet by Panelview. 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. Kick-off voltage at tA=0°C exceeds maximum value,1500 Vrms. In case of operating under lower temp environment, the lamp exhaistion is accelerated and the brightness
becomes lower.
(Continuous operating for around 1 month under lower temp condition may reduce the brightness to 50%.)
In case of such usage under lower temp environment, periodical lamp exchange by Panelview is recommended
Note:
1. The performance of the backlight, for example life time; or brightness, is extremely infuenced by the characteristics of the DC-AC inverter for the lamp. When designing or
ordering the inverter, make sure 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. Recommemded inverter is "CXA-L0612A-VJL(TDK corporation)".
