Display Panel Layout With Overlapping Driver and Corner Pixels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face challenges in increasing the screen-to-body ratio while maintaining high display quality, as reducing the peripheral area is difficult due to the need for increased driver regions for fast driving capabilities.
Innovation Solution
The display device incorporates a corner portion with a round shape, utilizing a second display area with second light emitting elements that are electrically connected and overlap the driving circuit, allowing for a reduced peripheral area and increased screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the peripheral area is reduced to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the driver region area is insufficient for fast driving capabilities
Solution Approach 1:
The patent extends the display area into the peripheral region by placing second light emitting elements in the second display area that overlaps with the driver region. This dimensional extension allows the screen-to-body ratio to increase while maintaining sufficient driver region area for fast driving capabilities, as the drivers can be positioned in the overlapping region between the first and second display areas.
2Productivity
If drivers are positioned in the peripheral area for fast driving, then the fast driving capability is improved, but the peripheral area is increased
Solution Approach 1:
The patent merges the driver region with the second display area by positioning the drivers in the peripheral area that overlaps with the second display area. This merging allows the drivers to be integrated into the display structure, enabling fast driving capability while minimizing the additional peripheral area required, as the driver region and display region share the same physical space.
3Area of stationary object
If second light emitting elements are placed in the second display area to increase screen-to-body ratio, then the screen-to-body ratio is improved, but the light blocking is increased
Solution Approach 1:
The patent applies local quality by using a light blocking layer that selectively blocks light from specific second light emitting elements (e.g., even-numbered elements) while allowing other elements to emit light normally. This localized light blocking approach allows the screen-to-body ratio to be increased through the extended display area while minimizing the overall light blocking effect, as only specific regions are blocked rather than the entire second display area.
