Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a display light-transmitting region is disposed on the display panel with an under-screen camera positioned below it, then the user experience is improved, but the light transmittance of the display light-transmitting region becomes low, resulting in poor photographing effect
Solution Approach 1:
The patent transitions from a two-dimensional planar arrangement where driving circuits are disposed beneath the display light-transmitting region to a three-dimensional stacked architecture. The first pixel driving circuits are positioned in the function add-on region above the main display region, utilizing the vertical dimension to separate the optical path from the electrical wiring path. This spatial reconfiguration allows light to pass through the display light-transmitting region with minimal obstruction while maintaining electrical connectivity through transparent conductive lines.
Solution Approach 2:
The patent divides the display panel into distinct functional regions: a main display region containing second display pixels and a function add-on region containing first pixel driving circuits and first display pixels. This segmentation allows the driving circuits to be isolated from the primary light transmission path while still controlling display elements. The functional separation enables the under-screen camera to operate effectively without interference from driving circuit structures in the display light-transmitting region.
2Adaptability or versatility
If pixel driving circuits are disposed in the display light-transmitting region to drive display pixels, then the display function is achieved, but the light transmittance is reduced due to the presence of circuit structures
Solution Approach 1:
The patent introduces transparent conductive lines as intermediary elements to establish electrical connectivity between the first pixel driving circuits in the function add-on region and the first display pixels in the display light-transmitting region. These transparent lines serve as mediators that conduct electrical signals while allowing light to pass through with minimal attenuation. The transparent nature of these conductive lines resolves the contradiction by providing necessary electrical connectivity without significantly obstructing the optical path.
Solution Approach 2:
The patent applies different structural configurations to different regions of the display panel. In the function add-on region, pixel driving circuits are disposed to provide driving functionality, while in the display light-transmitting region, the structure is optimized for light transmission with minimal obstructive elements. The first display pixels are positioned to receive electrical signals through transparent lines while maintaining high light transmittance characteristics in this critical optical region.
