Display Pixel Voltage Line Stacking for Improved Aperture Ratio

The patent applies dimensionality change by transitioning from a planar voltage line layout to a three-dimensional stacked configuration. Multiple initialization voltage lines are arranged in different layers (first, second, and third initialization voltage lines on different conductive layers), allowing them to overlap in the vertical dimension while maintaining electrical connectivity through connecting members. This vertical stacking enables the aperture ratio to improve by reducing the horizontal space occupied by voltage lines, while the multi-layer structure manages the increased complexity through systematic spatial organization.

The patent segments the initialization voltage lines into multiple distinct components arranged in different layers. The first initialization voltage line is disposed on a second conductive layer, the second initialization voltage line on a fourth conductive layer, and the third initialization voltage line on a third conductive layer. Each segment can be fabricated independently using standard multi-layer conductive layer processes, making the manufacturing complexity manageable through incremental fabrication steps rather than requiring a completely new manufacturing approach.

The patent introduces connecting members as intermediary elements to bridge the electrical connection between voltage lines in different layers. These connecting members are disposed on conductive layers between the stacked initialization voltage lines, serving as mediators that transfer electrical signals vertically between layers. This intermediary approach simplifies the electrical connectivity management by providing dedicated connection pathways, rather than requiring complex direct inter-layer routing or through-substrate vias.
