Abstract:
A digital controlled multi-light driving apparatus for driving and controlling a plurality of lights. The digital controlled multi-light driving apparatus includes a plurality of oscillation step-up circuits and a digital control circuit. The digital control circuit has a counter unit, a memory unit, a comparator unit, and a driving unit. The counter unit starts counting to generate a counting value whenever a digital start signal is generated. The memory unit stores at least one target counting value. The comparator unit is electrically connected to the counter unit and the memory unit to generate triggering signals whenever the counting value matches the target counting value. The driving unit is electrically connected to the comparator unit to output sequentially delayed driving signals to the oscillation step-up circuits respectively on receiving the triggering signals.
Abstract:
A desktop liquid crystal displaying (LCD) device, which can be disposed on a surface, includes an LCD monitor, a first frame and a second frame. The LCD monitor has a bottom side facing the surface. The first frame and the second frame are mounted on the LCD monitor. The first frame and the second frame protrude from the bottom side of the LCD monitor towards the surface and are placed over the surface to support the LCD monitor. Portions of the first frame and the second frame extruding from the bottom side of the LCD monitor are distanced apart over 25 centimeters.
Abstract:
A diffusion unit of a light-emitting module is disposed adjacent to at least one light source. The light source emits a light beam. The diffusion unit includes a first diffusion sheet and a second diffusion sheet. The thickness of the first diffusion sheet is less than 1 mm, and the thickness of the second diffusion sheet is also less than 1 mm. The second diffusion sheet is disposed adjacent to the first diffusion sheet. The light beam is directly emitted from the light source directly to the first diffusion sheet. A light-emitting module and a diffusion sheet are also disclosed.
Abstract:
A control method for a backlight module having a driving circuit and at least one lighting element includes the steps of controlling the driving circuit to drive the lighting element according to a first-type control signal before a first time instant, controlling the driving circuit to drive the lighting element according to a transition modulation signal at a time instant between the first time instant and a second time instant, and controlling the driving circuit to drive the lighting element according to a second-type control signal after the second time instant.
