Description
technical field [0001] The present invention relates to a light emitting device, in particular to a light emitting device including a circuit substrate with double-sided circuits. Background technique [0002] In the current light-emitting device, due to the different positions of the light sources in the light-emitting device, the distance of each trace is different, which leads to an increase in the impedance difference of the overall circuit. If the IR drop is not improved, it will decrease. device performance. Contents of the invention [0003] According to an embodiment of the present invention, a light emitting device is provided, including: a circuit substrate, an array substrate, a plurality of light emitting units, and a driving device. Wherein the circuit substrate has an upper surface and a lower surface, an upper circuit is arranged on the upper surface, a lower circuit is arranged on the lower surface, and is electrically connected to the upper circuit; the a...
