Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices face challenges in achieving uniform transmittance across different areas of the display panel, particularly where electronic modules are integrated, leading to variations in display quality.
Innovation Solution
The display panel is designed with a first area having a higher transmittance and a second area with lower transmittance, incorporating a light emitting unit and a copy light emitting unit with synchronized emission colors and connections to enhance display quality, and includes a barrier layer with specific light blocking layers to optimize transmittance and visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the display panel integrates electronic modules in certain areas, then the functionality and versatility of the device are improved, but the transmittance uniformity and display quality are worsened due to visibility differences between areas with and without electronic modules
Solution Approach 1:
The patent applies local quality by implementing different light emitting characteristics in different areas of the display panel. Specifically, the first light emitting unit in the element area and the second light emitting unit in the connection area emit different colors of light (first color and second color respectively). This allows each area to have optimized properties for its specific function while maintaining overall display quality and transmittance uniformity across the panel.
2Adaptability or versatility
If different areas of the display panel have different transmittance characteristics to accommodate electronic modules, then the adaptability is improved, but the display quality consistency is worsened
Solution Approach 1:
The patent implements local quality by configuring different light emitting units to emit different colors in different areas. The first light emitting unit in the element area emits a first color while the second light emitting unit in the connection area emits a second color, allowing each region to be optimized for its specific purpose while maintaining consistent display quality across the entire panel.
Solution Approach 2:
The patent applies segmentation by dividing the display panel into distinct functional areas: an element area with a first light emitting unit and connection areas with second light emitting units. This segmentation allows independent optimization of each area's transmittance and light emitting characteristics to suit its specific function while maintaining overall display consistency.

AI summary
An electronic device includes a display panel with a first area including a transmissive area, an element area, and connection areas extending from the element area, and a second area. The display panel includes a first light emitting unit in the element area and including first, second, and third light emitting elements, and a first copy light emitting unit in the connection areas, including copy light emitting elements, and operating in synchronization with the first light emitting unit. The connection areas include a first connection area adjacent to the first light emitting element, a second connection area adjacent to the second light emitting element, and third and fourth connection areas adjacent to the third light emitting element. An emission color of the first light emitting element is different from an emission color of a first copy light emitting element of the copy light emitting elements in the first connection area.
