A backlight module and a driving circuit are provided. The driving circuit includes a plurality of current sources and a current switching unit. The current sources provide a plurality of driving currents. The current switching unit is coupled between a plurality of light emitting element strings and the current sources for transmitting the driving currents to the light emitting element strings, and switching the driving currents received by the light emitting element strings by timing. Therefore, the brightness of the light emitting element strings can be equalized.

An assembly for securing plates includes a first plate having two pairs of protruding portions, and a second plate having two tongue pieces at opposite ends thereof. Each of the protruding portions has a first guiding surface and a second guiding surface intersecting with the first guiding surface for the tongue piece sliding thereon. The tongue pieces firstly slide downwardly along the first guiding surfaces of the pair of protruding portions and are then clamped between the corresponding protruding portions, thereby detachably securing the second plate to the first plate.

An apparatus for digital-to-analog conversion and the method thereof is disclosed, wherein the complete scale-tuned levels of more bits may be presented with an output of less bits. The apparatus comprises a timing controller, a scale-tuned circuit and a digital-to-analog converter. The timing controller receives an a-bit grayscale value, and outputs a selection signal and a b-bit control signal, wherein a, b are both positive integers and a>b>=1. The selection signal has two states: if the grayscale value is less than or equal to 2a−2c, wherein c is equal to a−b, the selection signal is in a first state; and if the grayscale value is equal to 2a−2c+n, wherein n is an integer and 0

A support assembly for a portable device includes a base (10), a support body (20) and a holder (30) for holding the portable device. The support body extends from the base. A protrusion (25) is formed on the support body. The holder defines a cutout (37) and a groove (375). The cutout receives the support body. The protrusion of the support body slides into the groove of the holder to detachably mount the holder to the support body.
