Abstract

Provided are a light source module and a circuit board circuit device. The device comprises a substrate, a circuit layer, first electronic components, and second electronic components. The circuit layer is formed on a bearing surface of the substrate, and comprises a central circuit, a first circuit group, and a second circuit group which are disposed on a same plane. The first electronic components are disposed on the circuit layer and are electrically connected with the central circuit or the first circuit group. The second electronic components are disposed on the circuit layer and are electrically connected with the central circuit or the second circuit group. The central circuit passes through the first electronic components and the second electronic components and branches respectively extend among the first electronic components and substrate end edges and among the second electronic components and the substrate end edges. The first circuit group and the second circuit group respectively at least extend among the central circuit and the first electronic components, and among the central circuit and the second electronic components.

Description

technical field [0001] The present invention relates to a light source module and a circuit board circuit device; specifically, the present invention relates to a light source module and a circuit board circuit device using circuit substrate wiring. Background technique [0002] Existing displays use light source modules to provide light sources, such as LED light bars. Classified according to the light emitting modes of the light source modules, the light source modules include side-light light source modules and direct-light light source modules. For example, the edge light source module is disposed on the side of the light guide plate and emits light on the side. [0003] For example, please refer to Figure 1A and Figure 1B , Figure 1A It is a top perspective view of a known light source module circuit board; Figure 1B It is a side view of a conventional light source module circuit board. In practical applications, the light source module circuit board 8 is a doub...

AI Technical Summary

Problems solved by technology

like Figure 1B As shown, the light source module circuit board 8 has a thickness of 85, which is difficult to achieve light and thin products, and the material cost cannot be reduced due to the high cost of the double-layer circuit board.

In addition, the light source module circuit board 8 has layer change holes 910, 920, which are prone to coupling capacitance and signal noise

In addition, the layer-changing holes 910, 920 need to reserve an area to facilitate layer-changing, and it is difficult to shorten the width 75 of the substrate 80.

In other words, the light source module circuit board 8 has disadvantages such as thick board body and high material cost.
