The difference between the standard device 200 and the electric two-set 100 is that the standard device 200 senses the result (ie, 7 information) as the electronic device 1〇: the manufacturer wants to ^^ standard, Every electricity produced by Qian is produced under the == ray. L can be obtained with the standard device. The calibrated electronic device (10) senses the result and uses the μ system.兀 Just calculate the voltage ratio of the voltage signals W and S2, ” * voltage ratio to calibrate the sensing result of the photo sensor 1〇2. For example, the relationship between the illuminance of the illuminating light and the voltage and the voltage of the package according to the embodiment of the present invention is shown. It is assumed that the straight line m in FIG. 3 is generated under the calibration light of different illumination according to the voltage signal S1 generated by the calibration photon according to the light sensing 201126147 m^Cz/5-0-TW 33175twf.d〇c/n illuminance. The signal pressure value is formed. Among them, the linear equation of the line A1 can be expressed as y=ax, =$ B. The linear equation of 1 can be expressed as y. When the photo sensor ι〇2 is used, the control unit 1〇4 calculates the line A1. The ratio of the slope to the straight line B1, that is, the value of a/b, is also a voltage ratio of the J voltage signals S1 and S2 at the same calibration light PL intensity. The control unit may just multiply the slope ratio by the voltage signal S1 sensed by the photo sensor 102. The sensing result of the photosensor 102 may be the same as the sensing result of the standard photo sensor • 〇2. The slope of the straight line β1 is changed so that the meander line A1 overlaps. /, by adjusting the light sensor 1〇2 light sensing result to 4 quasi-light sensing 202, the control unit is the same, the control unit 1〇4 can be, according to the adjusted persimmon g 1G2 The associated specific work is performed such that the electronic device (10) can have the same product nature as the standard device. For example, the electronic device 100 of FIG. 1 , the correcting light PL, the sensor 102, must receive a receiving hole H1 through the electronic housing 100 before receiving the sensor 102. In order to improve the connection purity of the electronic device, it is usually composed of dyed materials, so that the receiving hole = two = 丄rf is difficult to control due to the uniformity of ink dyeing, so each electron, the correcting light pL received through the receiving hole H1 has a household ^ "This hollow order 70 1〇4 can adjust the light sensor 1依据 according to the 201126147 HTCU98275-0-TW 33I75twf.doc/n standard information and initial information stored in the electronic device and according to 驴The post-sensing effect is performed to perform the backlight module m adjustment so that the display panel 1 8 of the electronic device 100 and the display panel 208 of the standard setting are in the same loop. For example, although the specific function performed by the unit 1G4 is adjusted by the backlight mode 2, the control unit 104 can perform other functions according to the sensed result of the 102 calibration in other embodiments. . , Bu Jie Please refer to ==:!:== calibration method, = can be summarized as the following steps. First === Obtain standard information (step _) = , use 4 = : : look at the sensing characteristics of the electronic device. The communication (step i senses the corrected light to obtain the initial capital f). After taking the calibration, the standard information and the initial sensing voltage value are called according to the initial information and the standard information, and the voltage value represents the light intensity of the light sensor. Thus, by calibrating the specific function of the photosensor = production, the electronic coffee is not produced. The port is the same as the standard device. The invention utilizes fresh: #讯 and initial information to calibrate the manufacture of the electrical component; fruit: this can overcome the same product of the electronic device in the electronic device i:.; i mother a factory electronic device with the coffee although the invention has The present invention is disclosed in the above embodiments, but it is not intended to limit the present invention to the present invention.
