4 . General Description The A3 is a Color Active Matrix with an integral Cold Cathode Fluorescent Lamp(CCFL) backlight system. The matrix employs asi Thin Film Transistor as the active element. t is a transmissive type display operating in the normally white mode. This TFTLCD has a 5. inches diagonally measured active display area with XGA resolution(768 vertical by 24 horizontal pixel array). Each pixel is divided into Red, Green and Blue subpixels or dots which are arranged in vertical stripes. Gray scale or the brightness of the subpixel color is determined with a 8bit gray scale signal for each dot, thus, presenting a palette of more than 6M colors. The A3 has been designed to apply the LVDS(8bit,port) interface method. The A3 LCD is intended to support applications where high brightness, wide viewing angle, high color saturation, and high color depth are very important. n combination with the vertical arrangement of the subpixels, the A3 characteristics provide an excellent flat panel display for office automation products such as monitors.

6 3. Electrical Specifications 3. Electrical Characteristics The A3 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. Table 2. Electrical characteristics Parameter Symbol Values Min. Typ. Max.

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 DCAC nverter. So all the parameters of an inverter should be carefully designed so as not to produce too much leakage current from highvoltage 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.. f the lamp wire attach to conducting tape, TFTLCD Module have a low luminance and the inverter has abnormal action because leakage current occurs between lamp wire and conducting tape.. The specified current and power consumption are under the V CC =3.3V, 25 C, f V (frame frequency) =6Hz condition whereas mosaic(black & white) pattern shown in the [ Figure 3 ] is displayed. 2. The duration of rush current is about 2ms. 3. Operating voltage is measured under 25.The variance of the voltage is %. 4. The voltage above V BS should be applied to the lamps for more than second for startup. Otherwise,the lamps may not be turned on. Ver.. Jan. 3, 22 6/27

7 The output of the inverter must have symmetrical(negative and positive) voltage waveform and symmetrical current waveform.(unsymmetrical ratio is less than %) 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. Let s define the brightness of the lamp after being lighted for 5 minutes as %. T s is the time required for the brightness of the center of the lamp to be not less than 95%. The used lamp current is the lamp typical current. The lamp power consumption shown above does not include loss of external inverter under 25. The used lamp current is the lamp typical current. The life time is determined as the time at which brightness of lamp is 5% compared to that of initial value at the typical lamp current on condition of continuous operating at Requirements for a system inverter design, which is intended to have a better display performance, a better power efficiency and a more reliable lamp. t shall help increase the lamp lifetime and reduce its leakage current. a. The unbalance rate of the inverter waveform should be % below; b. The distortion rate of the waveform should be within 2 %; c. The ideal sine wave form shall be symmetric in positive and negative polarities. p * Asymmetry rate = p p / rms * % p * Distortion rate = p (or p ) / rms. nverter open voltage must be more than lamp starting voltage.

17 Notes. Contrast ratio(cr) is defined mathematically as Surface luminance with all white pixels Contrast ratio = Surface luminance with all black pixels 2. Surface luminance is the center point across the LCD surface 5cm from the surface with all pixels displaying white. For more information see [ Figure ]. When BL =8mA, L WH =2cd/m 2 (Min.) 25cd/m 2 (Typ.) 3. The variation in surface luminance, WHTE is determined by measuring L ON at each test position through 5, and then dividing the maximum L ON of 5 points luminance by minimum L ON of 5 points luminance. For more information see [ Figure ]. WHTE = Maximum(L ON,L ON2,.. L ON5 ) Minimum(L ON,L ON2,.. L ON5 ) 4. Response time is the time required for the display to transition from to black(rise Time, Tr R ) and from black to white(decay Time, Tr D ). For additional information see [ Figure ]. 5. Viewing angle is the angle at which the contrast ratio is greater than. The angles are 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 [ Figure 2 ]. 6.

26 9. Precautions Please pay attention to the following when you use this TFT LCD module. 9. Mounting Precautions () 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 a 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 describe because the former generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break by electrochemical 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 determined 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. Normalhexane 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. 92. Operating Precautions () The spike noise causes the misoperation of circuits. t should be lower than following voltage V= 2mV(Over and under shoot voltage) (2) Response time depends on the temperature.(n lower temperature, it becomes longer.) (3) Brightness depends on the temperature. (n 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. Ver.. Jan. 3, 22 26/27

27 93. 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. 94. Precautions for Strong Light Exposure Strong light exposure causes degradation of polarizer and color filter. 95. Storage When storing modules as spares for a long time, the following precautions are necessary. () 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. t is recommended that they be stored in the container in which they were shipped. 96. Handling Precautions for Protection Film () 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 or its vestige is recognized, please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normalhexane. Ver.. Jan. 3, 22 27/27
