    • This invention relates to a backlight unit that is adaptive for increasing brightness uniformity, and a liquid crystal module using the same. The backlight unit includes a plurality of light emitting diodes with the (2i −1)th (where i is a natural number) light emitting diodes of the plurality connected in a first series circuit between an input terminal and an output terminal and the 2ith light emitting diodes of the plurality connected in a second series circuit. The second series circuit is connected in parallel with the first series circuit between the input terminal and the output terminal, and each of the 2ith light emitting diodes is disposed adjacent to a respective (2i−1)th light emitting diode.

    • A temperature measuring method has the steps of (a) coating a mixture of fluorescent dye on a surface of the micro device, (b) heating the micro device with a calibration heater, (c) acquiring an emission intensity image of the mixture with a camera by illuminating the surface of the micro device with a light, (d) averaging the emission intensity image by units of a plurality of pixels, (e) calculating a temperature calibration curve indicating a change of the emission intensity with respect to the temperature, from the image averaged by units of a plurality of pixels, and (f) removing the calibration heater, acquiring an emission intensity image by actually driving the micro device, and converting the acquired emission intensity image into a temperature, using the temperature calibration curve. According to the method, the temperature calibration curve is obtained through the averaged emission intensity image, and a temperature field on the micro device is measured using the temperature calibration curve. Thus, the emission intensity of fluorescent dye can correct a deviation occurring between each pixel of the image, thereby making it possible to precisely measure the temperature field in microscale.
    • 温度测量方法具有以下步骤:(a)在微器件的表面上涂布荧光染料的混合物,(b)用校准加热器加热微器件,(c)用a获得混合物的发射强度图像 通过用光照亮微器件的表面,(d)以多个像素为单位平均发光强度图像;(e)计算表示相对于温度的发光强度变化的温度校准曲线, 从(f)去除校准加热器,通过实际驱动微型装置获取发射强度图像,并使用温度校准曲线将获取的发射强度图像转换成温度。 根据该方法,通过平均发射强度图像获得温度校准曲线,并使用温度校准曲线测量微器件上的温度场。 因此,荧光染料的发光强度可以校正图像的每个像素之间发生的偏差,从而可以以微观尺度精确地测量温度场。
