Liquid Crystal Display
1. General description
LM230WF5-TLA1 is a Color Active Matrix Liquid Crystal Display Light Emitting Diode ( White LED) backlight
system without LED driver. The matrix employs a-Si Thin Film Transistor as the active element. It is a
transmissive type display operating in the normally white mode. It has a 23 inch diagonally measured active
display area with FHD resolution (1080 vertical by 1920 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
16,7M colors with Advanced-FRC(Frame Rate Control). It 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. It 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 LM230WF5-TLA1 characteristics provide an excellent flat panel display for office automation
products such as monitors.

3. Electrical specifications
3-1. Electrical characteristics
It requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and
liquid crystal. The second input power for the CCFL/Backlight, is typically generated by an inverter. The
inverter is an external unit to the LCDs.

whereas mosaic pattern(8 x 6) is displayed and fV is the frame frequency.
2. The current is specified at the maximum current pattern.
3. Permissive power ripple should be measured under VCC=5.0V, 25°C, fV (frame frequency)=75Hz
condition and At that time, we recommend the bandwidth configuration of oscilloscope
is to be under 20MHz.
4. The duration of rush current is about 2ms and rising time of power Input is 500us ± 20%.

LED driver design guide
: The design of the LED driver must have specifications for the LED in LCD Assembly.
The performance of the LED in LCM, for example life time or brightness, is extremely influenced by
the characteristics of the LED driver.
So all the parameters of an LED driver should be carefully designed and output current should be
Constant current control.
Please control feedback current of each string individually to compensate the current variation
among the strings of LEDs.
When you design or order the LED driver, please make sure unwanted lighting caused by
the mismatch of the LED and the LED driver (no lighting, flicker, etc) never occurs.
When you confirm it, the LCD module should be operated in the same condition as installed in
your instrument.
1. Specified values are for a single LED bar.
2. The specified current is input LED chip 100% duty current.
3. The specified voltage is input LED string and Bar voltage at typical 110 mA 100% duty current.
4. The specified power consumption is input LED bar power consumption at typical 110 mA 100% duty current.
5. The life is determined as the time at which luminance of the LED is 50% compared to that of initial
value at the typical LED current on condition of continuous operating at 25 ± 2°C.
6. The LED bar power consumption shown above does not include loss of external driver.
The used LED bar current is the LED typical current.
Min Power Consumption is calculated with PBar = Vs(Min.) x Is(Typ.) x Nstring
Max Power Consumption is calculated with PBar = Vbar(Max.) x Is(Typ) x Nstring
7. LED operating DC Forward Current and Junction Temperature must not exceed LED Max Ratings at 25 ± 2°C.

1. DE Only mode operation. The input of Hsync & Vsync signal does not have an effect
on LCD normal operation.
2. The performance of the electro-optical characteristics may be influenced by variance of the
vertical refresh rates.
3. Horizontal period should be even.

3-6. Color input data reference
The brightness of each primary color (red,green and blue) is based on the 8bit gray scale data input for the
color ; the higher the binary input, the brighter the color. The table below provides a reference for color versus

Optical characteristics are determined after the unit has been ‘ON’ for 30 minutes in a dark environment at
25°C. The values specified are at an approximate distance 50cm from the LCD surface at a viewing angle of
Φ and θ equal to 0 °.

9. Precautions
Please pay attention to the followings when you use this TFT LCD module.
9-1. Mounting Precautions
(1) You must mount a module using holes arranged in four corners or four sides.
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is
not applied to the Module. And the case on which a module is mounted should have
sufficient strength so that external force is not transmitted directly to the module.
(3) Please attach the surface transparent protective plate to the surface in order to protect
the polarizer. Transparent protective plate should have sufficient strength in order to the
resist external force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because
the former generates corrosive gas of attacking the polarizer at high temperature and the
latter causes circuit break by electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder
than HB pencil lead. And please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth.
(Some cosmetics are detrimental to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft
materials like chamois soaks with petroleum benzene. Normal-hexane is recommended
for cleaning the adhesives used to attach front / rear polarizers. Do not use acetone,
toluene and alcohol because they cause chemical damage to the polarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer
causes deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient strength.
9-2. Operating precautions
(1) The spike noise causes the mis-operation of circuits. It should be lower than following
voltage : V=± 200mV(Over and under shoot voltage)
(2) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes higher.)
And in lower temperature, response time(required time that brightness is stable after
turned on) becomes longer.
(4) Be careful for condensation at sudden temperature change. Condensation makes damage
to polarizer or electrical contacted parts. And after fading condensation, smear or spot will
occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic
interference shall be done by system manufacturers. Grounding and shielding methods
may be important to minimized the interference.
(7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can
not be operated its full characteristics perfectly.
(8) A screw which is fastened up the steels should be a machine screw (if not, it causes metal
foreign material and deal LCM a fatal blow)
(9) Please do not set LCD on its edge.
