Abstract: A computing device and an input device are provided. Each of the computing device and the input device includes a control unit, a light source, a projection plate and a casing. The control unit, the light source and the projection plate are accommodated within the casing. The light source emits light beams. The projection plate includes a pattern. After the light beams pass through the projection plate, the light beams are projected outside the casing and an image corresponding to the pattern of the projection plate is formed on a projection surface that is located outside the casing. Since the projection plate is cheap and small, the fabricating cost of the computing device or the input device is reduced and the purpose of developing the computing device or the input device toward light weightiness, slimness and small size is achievable.

Abstract: A color adjusting method for a color light-emitting element is provided. Firstly, a first white light beam is produced by red, green and blue light-emitting units collaboratively, and a second white light beam is produced by a white light-emitting unit. Then, a second chromaticity value corresponding to the second white light beam is acquired. Then, the red, green and blue light-emitting units are controlled to produce a third white light beam according to the second chromaticity value, and a first adjusting parameter is acquired. Then, the white light-emitting unit is controlled to produce a fourth white light beam according to a third luminance value corresponding to the third white light beam, and a second adjusting parameter is acquired. Then, a gray level adjustment process is performed according to the first and second adjusting parameters.

Abstract: A light source module includes a transparent conductive substrate and plural light source groups. The transparent conductive substrate includes a substrate base, plural positive electrodes, plural negative electrodes and plural gaps. The plural positive electrodes and the plural negative electrodes are installed on the substrate base. Each light source group includes plural light-emitting elements. The plural positive electrodes are separately arranged. Consequently, the resistances of the light-emitting elements are substantially equal.

Abstract: An input system includes a first input device and a second input device. Each of the first input device and the second input device includes a main body, a first connecting port, at least two second connecting ports, a power switching circuit and a control unit. When the first connecting port of the first input device is connected with an external power source, the power switching circuit of the first input device receives a first voltage from the external power source. When one of the second connecting ports of the first input device is connected with one of the second connecting ports of the second input device, the first voltage is converted into a second voltage by the power switching circuit of the first input device and the second voltage is transmitted to the second input device.

Abstract: An input device includes a universal serial bus interface, a white light-emitting diode unit, a red light-emitting diode unit, a green light-emitting diode unit, a blue light-emitting diode unit and a driving part. The driving part receives electricity through the universal serial bus and drives at least one of the white light-emitting diode unit, the red light-emitting diode unit, the green light-emitting diode unit and the blue light-emitting diode unit to emit a light beam. Consequently, the light beam with a higher luminous intensity and a specified color is outputted from the input device.
