  • Publication number: 20240243114
    Abstract: An electronic package structure includes first and second package modules combined with each other. The first package module includes a substrate and a first electronic component disposed thereon, at least one second electronic component, and an insulation film. The first electronic component and the second electronic component are adjacent to each other. The insulation film includes a base material and a foam glue body, and the foam glue body is viscous and compressible. The second package module includes a heat dissipation plate and a liquid metal and an insulation protrusion portion disposed thereon. The liquid metal is pressed by the heat dissipation plate and the first electronic component. The insulation protrusion portion covers and abuts against the insulation film to press the foam glue body through the base material so as to deform the foam glue body and enable the foam glue body to cover the second electronic component.

  • Publication number: 20240163987
    Abstract: A dimming circuit is configured to generate a dimming signal to control a brightness of a light emitting device. The brightness is correlated with a duty ratio of the dimming signal. The dimming circuit is configured to count a conduction time of the dimming signal according to a programmable period count code and a programmable brightness code, based upon a fundamental frequency, wherein when the conduction time is less than a conduction time lower limit, based upon a down conversion ratio, the dimming circuit reduces a frequency of the dimming signal according to the programmable period count code and the programmable brightness code, wherein the down conversion ratio is greater than 1 to an extent where a dimming conduction time is greater than or equal to a conduction time lower threshold.
