1. General Description
This specification applies to the 20.1 inch Color TFT-LCD Module T201VN01. This LCD module has a TFT active matrix type liquid crystal panel 640x480 pixels, and diagonal size of 20.1 inch. This module supports 640x480 VGA mode (Non-interlace). This module is without inverter. 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. The T201VN01 has been designed to apply the 8-bit 1 channel LVDS interface method. It is intended to support displays where high brightness, wide viewing angle, high color saturation, and high color depth are very important.

3. Electrical Specification
3-1 Electrical Characteristics
The T201VN01 requires two power inputs. One is employed to power the LCD electronics and to drive the TFT array and liquid crystal. The second input which powers the CCFL, is typically generated by an inverter. Parameter Symbol Min LCD: Power Supply Input Voltage Power Supply Input Current Power Consumption Inrush Current Lamp Power Consumption Life Time Vcc Icc Pc IRUSH 4.5 5.0 600 3.0. 41.04 50,000 5.5 4.7 Vdc mA Watt Apeak W 1 1 0.2ms 2 3 Values Typ Max Unit Notes
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. Note: The relative humidity must not exceed 80% non-condensing at temperatures of 40J or less. At temperatures greater than 40J , the wet bulb temperature must not exceed 39J . When operate at low temperatures, the brightness of CCFL will drop and the life time of CCFL will be reduced.

Note: 1.
The specified current and power consumption are under the Vcc=5.0V, 25J , fv= 60Hz, fCLK=25.2Mhz condition whereas mosaic pattern (8x6) is displayed and fv is the frame frequency.
Sequence of Power-on/off and signal-on/off
Apply the lamp voltage within the LCD operating range. When the backlight turns on before the LCD operation or the LCD turns off before the backlight turns off, the display may momentarily become abnormal. Caution: The above on/off sequence should be applied to avoid abnormal function in the display. In case of handling, make sure to turn off the power when you plug the cable into the input connector or pull the cable out of the connector. 2. 3. The lamp power consumption shown above does include loss of external inverter at 25J. The used lamp current is the lamp typical current The life is determined as the time at which luminance of the lamp is 50% compared to that of initial value at the typical lamp current on condition of continuous operating at 25OJ 2
Note: The output of the inverter must have symmetrical (negative and positive) voltage waveform and symmetrical current waveform (Asymmetry ratio is less than 10%). Please do not use the inverter which has asymmetrical voltage and asymmetrical current and spike wave. 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 asymmetry rate of the inverter current and voltage waveform should be 10% below; b. The distortion rate of the current and voltage waveform should be within O2O0%; 1 c. The ideal sine current and voltage waveform shall be symmetric in positive and negative polarities.

Note: 1. Contrast Ratio (CR) is defined mathematically as: Surface Luminance with all white pixels Contrast Ratio= Surface Luminance with all black pixels
1.
Surface luminance is luminance value at point 1 across the LCD surface 50cm from the surface with all pixels displaying white. From more information see FIG 2. When IBL = 5.0mA, LWH=500cd/T(typ.) LWH=Lon1 Where Lon1 is the luminance with all pixels displaying white at center 1 location.
2.
The variation in surface luminance, _WHITE is defined (center of Screen) as: _ WHITE(5P)=Maximum(Lon1, Lon2,... ,Lon5)/Minimum(Lon1, Lon2,... Lon5)
3.
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 FIG3.
4.
Viewing angle is the angle at which the contrast ratio is greater than 5. 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 FIG4.

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 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=O00mV(Over and under shoot voltage) 2 (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 minimize the interface.
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.

21/24
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 5J and 35J 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 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 flue 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 normal-hexane.
