LM230WF5

Liquid Crystal Display

Product Specification

1. General description

LM230WF5-TRA1 is a Color Active Matrix Liquid Crystal Display with an integral Light Emitting Diode (LED) backlight system. 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 23.0 inch diagonally measured active display area with Full HD 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 6-bit gray scale signal for each dot, thus, presenting a palette of more than 16,7M colors in case of using 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 mini-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-TRA1 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 LED/Backlight, is typically generated by an LED Driver. The LED Driver is an external unit to the LCDs.

* 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.

Values

Unit Notes

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 60 mA 100% duty current.

4. The specified power consumption is input LED bar power consumption at typical 60 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 r 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 = Vs(Max.) x Is(Typ) x Nstring

7. LED operating DC Forward Current and Junction Temperature must not exceed LED Max Ratings at 25 r 2¶C.

7. Luminance Uniformity - angular – dependence (LR& TB)

TCO ‘03 Luminance uniformity ୧ angular dependence, is the capacity of the VDU

to present the same Luminance level independently of the viewing direction. The angular-dependent luminance uniformity is calculated as the ratio of maximum luminance to minimum luminance in the specified measurement areas.

- Test pattern : 80% white pattern

- Test point : 2-point

- Test distance : D * 1.5 = 87.63

- Test method : LR = ((Lmax.+30deg. / Lmin. +30deg.) + (Lmax. -30deg. / Lmin.

-30deg.)) / 2 TB = ((Lmax.+15deg. / Lmin. +15deg.)

7. Precautions

Please pay attention to the followings when you use this TFT LCD module.

7-1. 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.

7-2. 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 lower.)

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.

7-3. Electrostatic discharge control

Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.

7-4. Precautions for strong light exposure

Strong light exposure causes degradation of polarizer and color filter.

7-5. Storage

www.panelook.com

LM230WF5

Liquid Crystal Display

Product Specification

When storing modules as spares for a long time, the following precautions are necessary.

(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep

the temperature between 5¶C and 35¶C at normal humidity.

(2) The polarizer surface should not come in contact with any other object.

It is recommended that they be stored in the container in which they were shipped.

7-6. Handling precautions for protection film

(1) The protection film is attached to the bezel with a small masking tape.

When the protection film is peeled off, static electricity is generated between

the film and polarizer. This should be peeled off slowly and carefully by people who are

electrically grounded and with well ion-blown equipment or in such a condition, etc.

(2) When the module with protection film attached is stored for a long time,

sometimes there remains a very small amount of glue still on the bezel after the protection film is peeled off.

(3) You can remove the glue easily. When the glue remains on the bezel surface or

its vestige is recognized, please wipe them off with absorbent cotton waste or

other soft material like chamois soaked with normal-hexane.
