1. General Description

The LM170E02-A5 is a Color Active Matrix Liquid Crystal Display with an integral Cold Cathode Fluorescent
Lamp(CCFL) backlight syst em. The matrix employs a-Si Thin Film Transistor as the active element.
It is a transmissive type display operating in the normally white mode. This TFT-LCD has a 17.0 inch diagonal
measured active display area with SXGA resolution(1024 vertical by 1280 horizontal pixel array)
Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arranged in vertical stripes.
Gray scale or the brightness of the sub-pixel color is determined with a 8-bit gray scale signal for each dot,
thus, presenting a palette of more than 16.2M colors with FRC(Frame Rate Control).

The LM170E02-A5 has been designed to apply the interface method that enables low power, high speed,low
EMI. FPD Link or compatible must be used as a LVDS(Low Voltage Differential Signaling) chip.
The LM170E02-A5 is intended to support applications where thin thickness,wide viewing angle, low power are
critical factors and graphic displays are important. In combination with the vertical arrangement of the sub-pixels,
the LM170E02-A5 characteristics provide an excellent flat panel display for office automation products such as
monitors.

3. Electrical specifications
3-1. Electrical characteristics

The LM170E02-A5 requires two power inputs. One is employed to power the LCD electronics and to
drive the TFT array and liquid crystal. Another which powers the CCFL, is typically generated by an inverter.

The inverter is an external unit to the LCD.

Note. The design of the inverter must have specifications for the lamp in LCD Assembly.

The performance of the Lamp in LCM, for example life time or brightness, is extremely influenced by
the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully
designed so as not to produce too much leakage current from high-voltage output of the inverter.
When you design or order the inverter, please make sure unwanted lighting caused by the mismatch of
the lamp and the inverter(no lighting,flicker,etc) never occurs.When you confirm it,the LCD Assembly
should be operated in the same condition as installed in your instrument.

Note. Do not attach a conducting tape to lamp connecting wire. If the lamp wire attach to conducting tape,

TFT-LCD Module have a low luminance and the inverter has abnormal action because leakage current
occurs between lamp wire and conducting tape.

1. The specified current and power consumption are under the V

=5.0V, 25°C, fV(frame frequency)

CC

=60Hz condition. Mosaic(black & white) pattern shown in the [ Figure 3 ] is displayed.

2. The duration of rush current is about 5ms. And V

rise time is 500us ± 20%.

CC

3. Operating voltage is measured under 25℃.The variance of the voltage is ±10%.

4. The voltage above V

should be applied to the lamps for more than 1 second for start-up.

BS

Otherwise,the lamps may not be turned on.

6

5. The output of the inverter must have symmetrical(negative and positive) voltage waveform and
symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter
which has unsymmetrical voltage and unsymmetrical current and spike wave.
Lamp frequency may produce interference with horizontal synchronous frequency and as a result this
may cause beat on the display.Therefore lamp frequency shall be as away as possible from the
horizontal synchronous frequency and from its harmonics in order to prevent interference.

6. Let’s define the brightness of the lamp after being lighted for 5 minutes as 100%.
T

is the time required for the brightness of the center of the lamp to be not less than 95%.

s

The used lamp current is the lamp typical current.

7. The lamp power consumption shown above does not include loss of external inverter under 25℃.
The used lamp current is the lamp typical current.

8. The life time is determined as the time at which brightness of lamp is 50% compared to that of initial
value at the typical lamp current on condition of continuous operating at 25 ±2℃.

9. Requirements for a system inverter design, which is intended to have a better display performance,

a better power efficiency and a more reliable lamp.
It shall help increase the lamp lifetime and reduce its leakage current.

a. The unbalance rate of the inverter waveform should be 10% below;
b. The distortion rate of the waveform should be within √2 ±10%;
c. The ideal sine wave form shall be symmetric in positive and negative polarities.

10. Inverter open voltage must be more than lamp starting voltage.

11. The inverter which is combined with this LCM, is highly recommended to connect coupling(ballast)

condenser at the high voltage output side. When you use the inverter which has not coupling(ballast)
condenser, it may cause abnormal lamp lighting because of biased mercury as time goes.

3-2. Interface Connections

Interface chip must be used LVDS, part No. SN75LVDS83 (Tx, Texas Instrument) or compatible.
This LCD employs a interface connection, a 30 pin connector is used for the module electronics interface.
Four 2pin connectors are used for the integral backlight system. The electronics interface connector is
a model MDF76LBRW-30S-1H manufactured by Hirose or compatible connector. And mating connector is
FI-X30H and FI-X30HL or it’s compatible manufactured by JAE.
The pin configuration for the connector is shown in the table 3 and the signal mapping with LVDS transmitter
is shown in the table 4.
