Display Device Load Compensation for Sensor Transmission Regions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices face challenges in minimizing luminance differences across regions, particularly when a transmission region is integrated into the front display area, affecting image quality and resolution.
Innovation Solution
A display device design that includes a load compensation element in the side display regions, connected to first pixels in the front display regions via a connection line detouring the transmission region, to balance load values and compensate for differences in pixel density, thereby minimizing luminance variations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmission region is formed in the front display region to accommodate a sensor device, then the sensor device can be integrated into the display, but luminance differences occur in the front display region
Solution Approach 1:
The patent applies local quality by creating a transmission region with different optical properties in a specific location of the front display region. This transmission region allows light to pass through to accommodate the sensor device, while the surrounding regions maintain normal light-blocking properties. The connection line is routed through this transmission region to electrically connect pixels on opposite sides, solving the luminance difference issue by utilizing the existing transmission area rather than creating additional disruptions.
2Adaptability or versatility
If a transmission region is created in the front display region, then a sensor device can be positioned there, but the resolution and image quality of the front display region deteriorate
Solution Approach 1:
The patent uses the transmission region as an intermediary space that serves dual purposes: it allows light transmission for the sensor device while also providing a pathway for the connection line. The connection line acts as a mediator that electrically connects pixels separated by the transmission region, ensuring that the display resolution and image quality are maintained despite the presence of the transmission region.
3Reliability
If pixels are connected directly across the transmission region, then electrical connection is achieved, but luminance differences and resolution loss occur
Solution Approach 1:
The patent routes the connection line through the transmission region, utilizing the vertical dimension and the existing optical transmission pathway. Instead of creating a horizontal disruption in the pixel array, the connection line passes through the transmission region from one side to the other, effectively using the transmission region as a conduit. This dimensional approach allows electrical connection without compromising luminance consistency or resolution.

AI summary
A display device includes a display panel including a substrate including a front display region, a side display region extending from a side of the front display region, and a transmission region including at least a portion overlapping the front display region in a plan view; and a sensor located on a bottom of the substrate, the sensor having at least a portion overlapping the transmission region in a plan view. The display panel includes first pixels in the front display region; a load compensation element in the side display region; and a connection line electrically connecting the first pixels and the load compensation element by detouring the transmission region.
