    Abstract: A driving method and driving apparatus for light emitting diodes in a keyboard are provided. The driving method includes the following steps: obtaining a first driver color data table unmatched with a key light driver array from a first memory; generating a second driver color data table matched with the key light driver array in a second memory according to an arrangement order of keys in the key light driver array and the first driver color data table; driving the key light driver array according to the second driver color data table; and driving the light emitting diodes corresponding to keys in the keyboard through the key light driver array.

    Abstract: A digital image converting apparatus with auto-correcting phase and a method thereof are provided. The digital image converting apparatus includes a phase controller, a delay locked loop (DLL), an analog-to-digital converter (ADC) and a position adjuster. The phase controller selects one of preset phases for outputting and continuously changes the output preset phase for controlling a clock signal produced by the delay locked loop. The ADC converts an analog display frame according to the adjusted clock signal. After all the preset phases are output in sequence, the phase controller can obtain an optimal phase for converting the display frame according to the smallest front porch of horizontal scan line and the smallest back porch of horizontal scan line of a digital display frame produced by the position adjuster.
