Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If pixel density is reduced and driving circuits are shifted to edge positions to achieve high light transmittance, then light transmittance is improved, but the width of the edge position increases and signal wire distribution becomes complex
Solution Approach 1:
The display area is divided into a first display area with first pixel driving circuits and a light-transmitting display area with second pixel driving circuits. This segmentation allows the light-transmitting area to have reduced pixel density for high light transmittance while the first display area maintains normal pixel density, resolving the contradiction between light transmittance and edge width.
Solution Approach 2:
Second pixel driving circuits electrically connected to second light-emitting devices in at least two columns are located in the same column, utilizing vertical stacking in the column dimension. This dimensional reorganization consolidates driving circuits in the column direction, reducing the horizontal edge width while maintaining signal distribution capability to multiple columns.
2Illumination intensity
If pixel density is reduced in the light-transmitting area, then light transmittance is improved, but signal distribution complexity increases
Solution Approach 1:
Multiple second pixel driving circuits are merged into the same column location, where a single column position houses driving circuits for multiple columns of light-emitting devices. This merging simplifies signal wire distribution by consolidating connection points while maintaining the ability to drive multiple columns through the stacked circuit architecture.
3Area of stationary object
If second pixel driving circuits are centralized in the same column, then edge width is reduced and light transmittance is improved, but signal distribution to different columns must be managed
Solution Approach 1:
Second pixel driving circuits in the same column are designed to provide display signals to light-emitting devices in multiple different columns simultaneously. Each driving circuit performs multiple functions by serving multiple columns, which manages the signal distribution complexity while maintaining the centralized column structure that reduces edge width.
