A display panel design that incorporates a first area for combining various functions within the display panel, utilizing a data distributor with switches to efficiently route data signals to data lines, and arranging data lines to overlap in the intermediate area, thereby minimizing the non-display area and optimizing image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If data lines are arranged in the intermediate area to minimize non-display area, then the area efficiency is improved, but the coupling capacitance between adjacent data lines increases
Solution Approach 1:
The patent applies dimensionality change by routing data lines through different spatial layers. Specifically, first data lines are arranged in the intermediate area while second data lines are arranged in the display area, utilizing the third dimension (vertical stacking) to separate signal paths. This reduces coupling capacitance between adjacent data lines while still minimizing the overall non-display area, as the lines occupy different z-heights rather than being tightly packed in the same plane.
2Adaptability or versatility
If a first area is incorporated for various functions within the display panel, then the versatility is improved, but the device complexity increases
Solution Approach 1:
The patent implements multi-functionality by designing the first area to serve multiple purposes: it functions as both a non-display area for housing circuitry (data distributor, switches, data lines) and as a structural region that contributes to the overall panel architecture. The intermediate area contains the data distributor and switches that control multiple data lines, allowing a single region to perform routing, switching, and signal distribution functions simultaneously, thereby reducing the need for separate dedicated areas for each function.

AI summary
A display panel including a substrate having a first area (OA), a display area (DA), and an intermediate area (MA) between the first area and the display area; a plurality of data lines (DL) extending in a first direction in the display area; and a data distributor (150) including switches electrically connected to the plurality of data lines. The plurality of data lines include a first data line DL1 and a second data line DL3, and each of the first data line and the second data line bypasses an edge of the first area in the intermediate area, and a bypass portion of the first data line and a bypass portion of the second data line overlap each other in the intermediate area.
