Liquid Crystal Display

Product Specification

1. General Description

LM215WF3 is a Color Active Matrix Liquid Crystal Display with 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 black mode. It has a 21.5inch diagonally measured active display area with Full HD resolution (1920 vertical by 1080 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 8bit gray scale signal for each dot, th u s, pr ese nt in g a p a le tt e of mo r e t ha n 16M co lor s. .

It has been designed to apply the 8bit 4Lane Display port interface.

It is in te nd ed to s up po rt di spl ay s wh er e h i g h b ri gh t n e s s , s u pe r w id e vi ew in g a ng le, high color saturation, and high color are important.

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 350mA 100% duty current.

4. The specified power consumption is input LED bar power consumption at typical 350mA 100% duty current.

5. The LED life time is determined as the time at which brightness of the LED is 70% compared to that of initial value at the typical LED current on condition of continuous operating at below junction temperature 90°C.

6. The LED power consumption shown above does not include loss of external driver. The used LED BL current is the LED typical current.

String Power Consumption is calculated with PS= VSx 350mA

BL Power Consumption is calculated with PBL= VSx 350mA x 2(string no.)

7. LED operating DC Forward Current and Junction Temperature must not exceed LED Max Ratings.

8. The LED life time and the maximum rating of LED junction temperature are evaluated at LED package level, not at liquid crystal module level.

Notes 1. Contrast Ratio(CR) is defined mathematically as :

It is measured at center point(Location P1)

2. Surface luminance(LWH)is luminance value at 5 points average across the LCD surface 50cm from the surface with all pixels displaying white. For more information see FIG 9.

= = Average[ Lon1,Lon2,Lon3,Lon4,Lon5]

3. The variation in surface luminance ,  WHITE is defined as :

Where L1 to L13 are the luminance with all pixels displaying white at 13 locations.

For more information see FIG 9.

4. Response time is the time required for the display to transition from black to white (Rise Time, TrR) and from white to black (Decay Time, TrD). For additional information see FIG 10

determined for the horizontal or x axis and the vertical or y axis with respect to the z axis which is normal to the LCD surface. For more information see FIG 12.

7. Effective viewing angle is the angle at which the gamma shift of gray scale is lower than 0.3.

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.

www.jxlcd.com

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 higher 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‟t be operated

its full characteristics perfectly.

(8) A screw which is fastened up the steels should be a machine screw.

(if not, it causes metallic foreign material and deal LCM a fatal blow)

(9) Please do not set LCD on its edge.

9-3. 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.

9-4. PRECAUTIONS FOR STRONG LIGHT EXPOSURE

Strong light exposure causes degradation of polarizer and color filter.

9-5. STORAGE

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.

9-6. 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 ionblown 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 normalhexane.
