Abstract: A display includes first and second pixel devices. The first pixel device includes a first control circuit and a first light emitting circuit. The first control circuit generates a first light emitting signal according to a first clock signal and a data signal during a first period. The first light emitting circuit emits light according to the first light emitting signal during second and third periods. The second pixel device includes a second control circuit and a second light emitting circuit. The second control circuit generates a second light emitting signal according to a second clock signal and the data signal during the second period. The second light emitting circuit is coupled to the second control circuit and emits light according to the second light emitting signal during the third period. The first period to the third period are arranged continuously in order.

Abstract: A backlight module is provided, including a circuit board, a plurality of light-emitting elements, a frame, and a plurality of first and second light-reflecting portions. The light-emitting elements are disposed on the circuit board and separated from each other. The frame includes a base plate and two lateral plates extended from the base plate, wherein the circuit board is disposed on the base plate. The first and second light-reflecting portions are disposed on at least one of the lateral plates and arranged in a staggered manner. The first light-reflecting portions are closer to the light-emitting elements than the second light-reflecting portions. The reflectivity of the second light-reflecting portions exceeds that of the first light-reflecting portions.

Abstract: A dimming module and a solid state lighting device are shown. The dimming module includes a rectifying circuit, a phase control circuit, a processing circuit and a first driving circuit. The rectifying circuit is configured to convert an input AC voltage to a rectified voltage signal. The phase control circuit is configured to receive the rectified voltage signal and a dimming command, and output a control voltage signal correspondingly in which the phase control circuit controls a phase delay angle of the control voltage signal according to the dimming command. The processing circuit is configured to receive the control voltage signal and adjust a first driving voltage signal according to the phase delay angle. The first driving circuit is configured to receive the first driving voltage signal to drive a first lighting module.

Abstract: A dimming module and a solid state lighting device are shown. The dimming module includes a rectifying circuit, a first driving circuit, and a processing circuit. The rectifying circuit is configured to convert an AC voltage to a rectified voltage. The first driving circuit is configured to receive the rectified voltage to provide a first current so as to drive a first lighting module. The first driving circuit includes a first switch. The first switch turns ON or OFF selectively according to a first control voltage signal so as to control the first current. The processing circuit is configured to receive a dimming command, and adjust the first control voltage signal according to the dimming command. The first control voltage signal is configured to control a phase delay angle and a duty cycle of the first current.
