Display Panel Driving-Circuit Layout for Data-Line Space and Transmittance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display panels face inadequate wiring space for data lines in transition regions between photosensitive and display regions, which hinders the implementation of full-screen displays with integrated photosensitive functions.
Innovation Solution
The display panel is designed with a first region having higher light transmittance than a second region, featuring first and second driving circuits arranged in non-parallel arrays, with first driving circuits closer to the center of the first region, ensuring sufficient wiring space for data lines and improving light transmittance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If driving circuits are arranged in conventional arrays in the transition region, then the display panel can be manufactured with standard processes, but the wiring space for data lines is insufficient
Solution Approach 1:
The patent applies asymmetry by arranging the first driving circuits in a non-parallel array configuration rather than a conventional parallel array. Specifically, the driving circuits are positioned at different distances from the center line of the transition region, creating an asymmetric layout that optimizes wiring space for data lines while maintaining manufacturing feasibility
Solution Approach 2:
The patent utilizes the transition region between the photosensitive region and display region as an additional dimensional space for placing driving circuits. By positioning driving circuits in this intermediate zone rather than solely within the display region, the patent creates additional wiring pathways and reduces congestion in the data line routing
2Area of stationary object
If more driving circuits are placed in the transition region to improve wiring space, then data line routing is facilitated, but light transmittance in the transition region decreases
Solution Approach 1:
The patent applies local quality by creating distinct light transmittance characteristics in different regions. The first region (photosensitive region) maintains high light transmittance for photosensitive operations, while the transition region accommodates driving circuits with reduced light transmittance requirements. This localized differentiation allows the transition region to serve dual purposes: housing driving circuits and permitting sufficient light passage
Solution Approach 2:
The patent segments the display panel into distinct functional regions: a photosensitive region with high light transmittance requirements, a transition region with moderate light transmittance that houses driving circuits, and a display region with standard light transmittance. This segmentation allows each region to be optimized for its specific function while minimizing overall compromise
3Area of stationary object
If first driving circuits are positioned closer to the center of the first region, then wiring space for data lines is increased, but the distance uniformity for signal routing is reduced
Solution Approach 1:
The patent deliberately employs asymmetric positioning of the first driving circuits relative to the center line of the transition region. By offsetting the driving circuits from a symmetric arrangement, the patent creates asymmetric wiring pathways that provide adequate clearance and routing space for data lines while maintaining controlled signal integrity through careful design of the asymmetric configuration

AI summary
A display panel and a display device including the same. The display panel comprising: a first region, a second region, and a transition region disposed between the first region and the second region. Light transmittance of the first region is greater than that of the second region. The display panel comprises: multiple first driving circuits and multiple second driving circuits, each of which are disposed in the transition region and arranged in an array along a first direction and a second direction which are not parallel. A distance between a center of one of first driving circuits and a center of the first region is smaller than a distance between a center of one of second driving circuits, which are connected to a same gate-signal line as the first driving circuits, and the center of the first region.
