A system for controlling multiple light sources is provided. The system includes a controller, a digital to analog converter (DAC), and at least one power amplifier. The controller is configured for receiving light control data for at least one light circuit, and for determining a digital luminance signal and an encoded address for each light circuit according to the light control data. The DAC is connected to the controller and configured for receiving the digital luminance signal and the encoded address for each light circuit, converting the digital luminance signal into an analog luminance signal, and for outputting the analog luminance signal according to the encoded address. Each power amplifier is connected to the DAC, and is configured for amplifying the analog luminance signal for the light circuit so as to drive the light circuit to control a corresponding light source.

A system and method for measuring a curve of an object includes aligning the ideal curve and the real point-cloud of the object, and defining a plurality of tolerance ranges for an area of a real curve of the object having a tolerance in a predetermined range. The method further includes determining a closest ideal point on the ideal curve corresponding to each real point in the real point-cloud, and assigning a serial number to each real point in the real point-cloud according to a sequence of the closest ideal points on the ideal curve. Furthermore, the method includes generating the real curve by connecting every two real points in the real point-cloud according to the serial number, and assigning a color to each line-segment according to the tolerance range in which two closest distances corresponding to two end-points of each line-segment fall.

A method for calculating coordinate values of a measuring machine is provided. The method includes receiving signals in three dimensions from a raster ruler signal generator, identifying a direction of each signal and multiply a frequency of each signal. The method further includes counting each of multiplied signals in each dimension, sending the counted data to the MCU. The method further includes adding the counted data of each of the multiplied signals in each dimension to obtain an accumulated number in each dimension and calculating coordinate values of the measuring machine according to the accumulated number in each dimension and a proportionality factor of the raster ruler signal generator.

A direct-light illuminating backlight unit with a reflective structure for a liquid crystal display has a case with a back, at least one lamp mounted in alignment with the back, a reflective layer formed on the back and facing the lamp. The case has a front opening that has at least one brighter region immediately in front of the lamp and at least one dimmer region away from the lamp. The reflective layer is composed of multiple reflective protrusions each has two inclined faces. Each inclined face projects light radiated backward from the lamp onto the dimmer region. Therefore, light emit from the illuminating backlight unit has a homogenous brightness.

A direct-light illuminating backlight unit for LCD module has two elongated lamps, each of which is bent into a substantial S-shape having three straight portions and two connection portions connected with the neighboring straight portions respectively. The lamps are mounted side by side on a frame with the straight portions of the lamps are substantially parallel to each other and interval pitches between the straight portions are substantially equal to each other. Such arrangement of the backlight unit is applied to LCD modules with nominal sizes ranged from 12 inches to 17 inches and more preferably applied to modules of, in name, 14 inches or 15 inches.
