Conductive structure and circuit apparatus

Abstract

The invention provides a conductive structure and a circuit apparatus; wherein, the conductive structure adopted by a power-supply circuit device comprises a base plate, a first conductive layer, a first isolating layer, a second conductive layer, a second isolating layer, a bridging conductive layer, a first through hole and a second through hole. The first conductive layer covers the base plate and the first isolating layer covers the first conductive layer; the second conductive layer partially covers the first isolating layer. The second isolating layer covers the second conductive layer and is exposed to the first isolating layer on the outside of the second conductive layer. The bridging conductive layer covers the second isolating layer. The first through hole is formed on an upper part of the first conductive layer and between two opposite second conductive layers and is simultaneously threaded through the second isolating layer and the first isolating layer. A plurality of second through holes are arranged on the upper part of the second conductive layer and are threaded through the second isolating layer. The first conductive layer and the second conductive layer are respectively and electrically connected with the bridging conductive layer through the conductive materials filled in the first through hole and second through holes. The invention reduces the burning possibility of the conductive layer and increases the charge flow paths with better durability.

Description

technical field [0001] The invention relates to a conductive structure and a circuit device, in particular to a conductive structure applied to the circuit device. Background technique [0002] Liquid Crystal Displays (LCDs) are widely used in various electronic products such as computers, televisions, and mobile phones. like Figure 1a As shown, the signal of the circuit device of the known liquid crystal display 99 is transmitted by the circuit. In the liquid crystal display 99, the signal outside the visible area 99a can be transmitted through the first metal layer 10, but in order to avoid interference between lines, part of the signal can be transferred to the second metal layer after entering the visible area 99a through the conductive structure 90. Layer 20 passes. Therefore, the durability and current conduction stability of the conductive structure 90 become one of the important factors affecting the performance of the liquid crystal display. [0003] like Figu...

Problems solved by technology

In other words, since the current is concentrated at the junction of the first metal layer and the second metal layer, the charge flux of the first through hole 50 far away from the second metal layer will be smaller, but the charge flow rate of the first through hole 50 closer to the second metal layer 20 will be smaller. The charge flux in the first through hole 50' will be relatively large, which will cause the indium tin oxide layer 80 in this area to be easily damaged, and cause the display screen to be abnormal.
