ENH150X1-200/300 Color TFT-LCD Module Features
GENERAL DESCRIPTION
Panelview provides optically enhanced solutions to the
standard Sharp LQ150X1DG16 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) providing
for up to 40% 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 1024 x 3
x 768 dot panel with 262, 144 color by supplying 36-bit
data signal (6bit x 2 pixel x RGB), four timing signals, +5V
DC supply voltage for TFT-LCD panel driving and supply
voltage for backlight.
It is a wide viewing-angle-module (Vertical viewing angle:
120° Horizontal viewing angle: 140°).
Input signal timing conforms with 75Hz mode of VESA
standard.
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.

BACKLIGHT DRIVING SECTION
The backlight system is an edge-lighting type with single CCFT (Cold Cathode Fluorescent Tube).
The characteristics of a single lamp are shown in the folliowing table. tA=25°C
The value mentioned below is at the case of one CCFT.

Notes:
1. A lamp can be lit in the range of the lamp current shown above.
Maximum rating for current is measured by high frequency current measurement equipment connected to VLOW at circuit shown below. (Note: To keep enough kick-off voltage
and necessary steady voltage for CCFT.)
Lamp frequency: 20~60kHz
Ambient temperature: 0~50°C

*3 pin is VLOW
2. Referential data per one CCFT by calculation (IL x VL).
The data does not include loss at inverter.
3. Lamp frequency of inverter may produce interference with horizontal synchronous frequency, and this may cause horizontal beat on the display. Therefore, adjust lamp frequency
keep inverter far from module or use electronic shielding between inverter and module to avoid interference.
4. The voltage above this value should be applied to the lamp for more than 1 second to startup. Otherwise, the lamp may not be turned on.
5. Lamp life time is defined as the time when either (1) or (2) under the continuous operation under the condition of tA=25°C and IL=6.0 ± 0.5mArms)
1. Brightness becomes 50% of the original value under standard condition.
2. Kick-off voltage at tA=0°C exceeds maximum value,1450 Vrms.
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 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.
