Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display technologies face issues of uneven display and complex wiring in the main display region due to the arrangement of second signal lines and pixel driving circuit islands in under-screen camera regions of active matrix organic light-emitting diode (AMOLED) panels, leading to impedance differences and display inconsistencies.
Innovation Solution

Engineering Contradiction Analysis
1Illumination intensity
If second signal lines are arranged around the light-transmitting region to connect pixel driving circuit islands, then light transmission of the light-transmitting region is increased, but wiring becomes complex and requires changes in wiring configuration
Solution Approach 1:
The display region is segmented into three distinct zones: light-transmitting region, transition display region, and main display region. Pixel driving circuit islands are specifically placed in the transition display region, which acts as an intermediate zone. This segmentation allows signal lines to connect to pixel driving circuits in the transition region without passing through the light-transmitting region, thus maintaining high light transmission while avoiding complex wiring changes.
Solution Approach 2:
The transition display region serves as an intermediary zone between the light-transmitting region and the main display region. Pixel driving circuit islands are positioned in this transition region, acting as mediators that receive signal lines from the main display region and drive pixels in both the transition and light-transmitting regions. This intermediary positioning eliminates the need for complex wiring around the light-transmitting region while maintaining full-screen display functionality.
2Ease of manufacture
If pixel driving circuit islands are arranged in the transition display region, then wiring is simplified and manufacturing process is easier, but display uniformity in the main display region may be affected
Solution Approach 1:
Different regions of the display are assigned different functional qualities: the light-transmitting region prioritizes light transmission, the transition display region houses pixel driving circuit islands with specific spacing and arrangement, and the main display region ensures display uniformity. The transition region's pixel driving circuits are designed with appropriate density and positioning to drive pixels in adjacent regions without compromising the uniformity of the main display region, thus achieving local optimization without sacrificing overall display quality.
3Reliability
If second signal lines are routed circuitously around the light-transmitting region, then connection to pixel driving circuit islands is achieved, but impedance differences cause uneven display in the main display region
Solution Approach 1:
Pixel driving circuit islands in the transition display region are positioned to receive signal lines with minimized impedance variations. The transition region acts as an equipotential zone where signal lines can connect to pixel driving circuits without experiencing significant impedance changes that would occur with circuitous routing around the light-transmitting region. This equipotential positioning ensures uniform signal distribution and consistent display quality across the main display region.
