Larger panels often require brighter = effective detection. If it is the detection condition (such as the type 1 of the flat panel display is changed, or if the backlight module is replaced ... the 7C degree corresponding to the dimming value will also change. At this time, if the aforementioned test conditions are changed, the specific dimming The brightness corresponding to the value will also change. 〃 200529152 Schematic n 2 mm light f system, ballast 30 circuit stabilizer 30, it is converted to DC power supply through the source supply voltage supplied to the rectifier. The Kugu circuit and the capacitors U and C2 turn off the semiconductors _, _, and then pass the open-frequency signal to the anti-current coil T2 ^ "T1 to signal. Kose. Called, the pressure is T3, so The lamp of the hot bulb. The rectified DC power supply dragon also transmits part of the current to the transformer. When the variable voltage of the transformer is output to the operational amplifier 1c, the output of the operational amplifier is equal to the output frequency of the two mu smoke g. 2 The output rate of the energy obtained by the output signal of Du mz is changed to the PUT element. On the other hand, the output of the oscillating transistor T1 5 will also change, so that the brightness of the light source can be controlled. Therefore, due to the traditional flat display The backlight module and security system of the detection device are set up, so the user must use the dimmer to handle ^. The shell of Zhou Zhengyue light module does not increase the inconvenience of operation. In addition, due to the brightness adjustment of the backlight module Because the ballast is fine-tuned, the flicker phenomenon also occurs when the ballast is turned on, which shortens the life of the backlight module bulb and shortens the life of the flat display. [Abstract] The main purpose of Ben Mingming is to provide a flat surface. The display detection device is self-controlled and controls the stabilizer with a dimming control circuit to perform brightness adjustment, so as to automatically control the brightness of the backlight module according to the size and classification of the flat display. Another object of the present invention is to provide a low- There is no flickering phenomenon when the brightness is 200529152. The backlight is extended by using two sets: a flat-panel detection device, including a table 4 state that includes a single device, including a dimming control circuit to continuously regulate one light source. -Stabilize the voltage to the backlight module; ―the brightness of the ^ th light source ^ and transmit the number to control the turn of the ——light source controller to dimming & Control system and delivery—control signal and a control module for transmitting the signal, and the size of the signal. The heart value is a source controller to decide to control the flat display detection device = and the axis brightness corresponds to the plane. The classification of the display = the classification or the detection method is changed. Does the tunnel operator display a pre-lower control signal to supply power to the DC power source and is between [Embodiment] Yes, the features and components of the present invention The example shown in Figure 2 will be used in conjunction with the implementation. The following is a good example to familiarize yourself with this technique == clear book = understand the technical means and implementation of the present invention. Examining the nuclear diagram carefully, Iϊ = ”. The present invention is shown Structure of the flat-panel display detection device. The flat-panel display detection device 100 includes a body to carry: a backlight module 120 under the body 110 to illuminate the hibiscus. A drive with stability 11 (baiiast all over the mountain). Stable voltage to f-light module 12G, a rectifier controller 140 = control drive module 13G, a control module ⑽ to supply power and power to the rectifier controller 控制器 40, a database 160 to store each panel Tone 200 529152 Jian'er classification, Nafa, and rotation. The entire back includes a Γ dimming control circuit 131, which is used to continuously adjust 140's so that the backlight module can set 10 = Jin 1ΐ according to the rectifier controller to emit appropriate brightness. When the flat panel monitor detects the mounted panel, the dimming control circuit 131 automatically adjusts the degree to emit light of appropriate brightness to illuminate the panel. Receiving the digital dimming value generated by the i4G according to the control module 150 will build the right corpse t J for the DC power supply. In addition, the ^ = ^ ^ of the internal controller of the rectifier controller 140 can be supplied to a control module 150 composed of a Γ program logic controller (PLC) to control the brightness of the corresponding dimming value and a backlight. The brightness data corresponding to the dimming value is received by the self-calibration unit 151, and the material is stored in the material storehouse within 16 °. The backlight controller 152's self-adjustable dimming f should be based on the panel classification or detection method input by the input unit 170; = device: Outputs a dimming value molding (such as panel classification and detection method) corresponding to the input value of the input unit 17 ° ) When changing, the brightness value of the backlight corresponding to the control 151, that is, the light value for 5 weeks will also change. The calibration unit is bad and needs this; ί = value: when the left backlight module's light bulb is damaged, the redundancy value of the calibration operation will also change. At this time, the brightness needs to be adjusted. That is, each of the extreme value disks of the present invention has 3 ^; ^ '1 ° _indicating that step S200 is to establish a tuning ⑽ LV said [, each increase in value for 5 weeks. In step S210, the brightness is reduced in the database. f. Store the data in step s22〇, and confirm whether the dimming value is equal to the maximum dimming 200529152 value at 4S230. When the dimming value is not equal to the maximum dimming value, steps S210 to ㈣ are performed by using a specific value that is increased by the establishment of $ ^ θ, that is, in step lake. M — Off value 'and then step S250 is performed. 4When the maximum dimming value is reached, the detection conditions (such as panel classification and size, and detection classification disk method) that are stopped will be stored. After being determined, the dimming value corresponding to each detection condition is stored to); == The table of the relative relationship with the value should be received from the calibration unit 151 to the shell value of the adjusted value. Figure ΐFigure 6 shows the rectifier controller block structure of the control ballast of the present invention. The rectifier controller 140 includes an interface unit 141 (such as a face) to receive digital control signals from the control module 150 and a central processing unit. / 丨 142 uses control operation, a read-only memory (ROM) 143, and a switch ^ -number = ratio converter 145 to generate an analog DC voltage of about 1 ¥ to the eye. The analog DC voltage of j IV to 10V is from the digital analog conversion world 145, to the dimming control circuit 131 of FIG. 3, so as to adjust the driving analog signal and finally adjust the brightness of the backlight module 120. Although the present invention uses a rectifier controller and 14 to increase the direct-k power supply voltage in the foregoing description, the same purpose can be achieved without departing from the spirit and scope of the present invention. For example, various resistors can be used to increase or decrease the voltage transmitted to the operational amplifier, and the resistance value can be between Γϋ. If it is a 10k resistor, the output frequency of the operational amplifier 1c is about t. Ξζζ If it is a 100k resistor, the output frequency of the operational amplifier ic is a dimming control circuit 131 which is built in the driver module 13 to automatically tune. The flicker phenomenon of the device can improve the device's: measuring the negative load and extending the life of the bulb. The brightness data of the brightness value of the light bulb which changes with the classification, base and production process of the substrate is stored in a table format ^ control module 200529152 150, and then selected according to the classification, size and production process of the panel. The display panel 2 ===== The circuit can be based on flat — In addition, the present invention effectively solves the problem of backlight at low brightness, thereby extending the life of the backlight.
