液晶显示器电源电路图220V交流市电通过交流保险管F101后进入由CXl01、LFl01等组成的抗干扰电路，经抗干扰电路处理后再进入BDl01进行整流。
为了防止瞬间大电流冲击，在整流后加入了THl01 NTC热敏电阻，最后经C101滤波生成约300V的直流电压。
从中可以看出，本电路不同于其他显示器开关电源的地方，一是THl01的位置不同(一般电路多设置在电源进线端)，另一点就是未设置电源开关，从而决定了只要插头接人市电，整个开关电源电路就开始工作，这也恰恰是借助于FAN7601优良的“绿色”功能来实现的。
整流滤波电路产生的约300V直流电压分两路输入开关电源电路，一路经开关变压器T1的①一②绕组加到开关管Q101的漏极。
另一路通过启动电阻R117加到开关电源PWM控制器FAN7601的①脚，通过启动控制电路由⑦脚对外部电容c108充电，当C108两端电压上升到11V时，FAN7601内部振荡电路起振，从⑥脚输出驱动脉冲，通过D103、R106、R107加到Q101栅极,使开关管工作于开关状态。
开关变压器各绕组有感应电压产生，通过各整流滤波系统向负载提供直流电压。
其中开关变压器的③-④绕组产生感应电压经R105限流、D102滤波后向FAN7601的⑦脚提供芯片工作电压，第 1 页启动控制电路关断①脚的电流输入。
第 2 页在以往的开关电源维修中，尽管采用启动电阻功率比较大但依然是易损元件之一，而且发热量也比较大，实际上就是由于通电后启动电阻一直有电流通过的原因。
而在这款电源中，启动电阻却采用了一个0Ω的贴片元件，是明显区别于其他电路的，这里我们学习到新型“绿色电源芯片”内部都设有一个启动开关，一旦电源达到正常工作状况(启动过程结束)，就会切断启动电阻器，这样便可省去一大部分的功率损耗。
其电路本身的故障率也接近于零该机稳压控制电路主要由U101、光电耦合器PC201、精密稳压器件U201(KIA431)及取样电阻R205、R211、R214、R210等组成。

The performance of the Lamp in LCD panel, for example life time or brightness, is extremelyinfluenced by the characteristics of the DC-AC Inverter. So all the parameters of an inverter should be carefully designed 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. After confirmation, the LCD panel should be operated in the same condition as installed in your instrument.6. 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.7. The relative humidity must not exceed 80% non-condensing at temperatures of 40 or less. At℃temperatures greater than 40, the wet bulb temperature must not exceed 39. When operate at ℃℃low temperatures, the brightness of CCFL will drop and the life time of CCFL will be reduced. 8. Specified values are for a single lamp only which is aligned horizontally. The lifetime is defined asthe time which luminance of the lamp is 50% compared to its original value.

PRECAUTIONSPlease 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 theformer 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 polarizer with glass, tweezers or anything harder thanHB 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 softmaterials like chamois soaks with petroleum benzene. Normal-hexane is recommended for cleaning the adhesives used to attach front/ rear polarizer. 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 polarizercauses deformations and color fading.(9) Do not open the case because inside circuits do not have sufficient strength.9-2 OPERATING PRECAUTIONS(1) The device listed in the product specification sheets was designed and manufactured for TVapplication(2) The spike noise causes the mis-operation of circuits. It should be lower than following voltage:V=±200mV(Over and under shoot voltage)(3) Response time depends on the temperature. (In lower temperature, it becomes longer..) (4) Brightness depends on the temperature. (In lower temperature, it becomes lower.) And inlower temperature, response time (required time that brightness is stable after turned on) becomes longer.(5) Be careful for condensation at sudden temperature change. Condensation makes damage topolarizer or electrical contacted parts. And after fading condensation, smear or spot will occur. (6) When fixed patterns are displayed for a long time, remnant image is likely to occur. (7) Module has high frequency circuits. Sufficient suppression to the electromagnetic interferenceshall be done by system manufacturers. Grounding and shielding methods may be important to minimize the interface.©Copyright AU Optronics, Inc.January, 2008 All Rights Reserved. T315XW02 VT - Specs. ver 0.5 30/31No Reproduction and Redistribution Allowed9-3 ELECTROSTATIC DISCHARGE CONTROLSince 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 EXPOSUREStrong 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 thetemperature between 5 and 35 at normal humidity.℃℃(2) The polarizer surface should not come in contact with any other object. It is recommended that they bestored 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 peeledoff, 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 verysmall amount of flue still on the Bezel after the protection film is peeled off.(3) You can remove the glue easily.
