OLED Display Panel With Transparent Hole Above Electronic Component
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing OLED display screens have a smaller screen-to-body ratio due to the large space occupied by O-cut and U-cut areas in the camera module, which reduces the available display area.
Innovation Solution
An OLED display panel design that includes a sub-pixel area with a transparent material-filled hole above an electronic component area, reducing pixel density and increasing light transmittance, and a thin film transistor layer with a corresponding hole filled with transparent material, allowing for a smaller electronic component area and higher screen-to-body ratio.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If O-cut area and U-cut area are designed in the camera area, then electronic component can be positioned, but non-display area increases and screen-to-body ratio decreases
Solution Approach 1:
The patent merges the electronic component area with the display area by positioning the camera module within the display region. The transparent material filled in the hole allows the display to function while accommodating the electronic component, effectively combining areas that were previously separate.
Solution Approach 2:
The patent applies local quality by creating a specific region with different optical properties - a hole filled with transparent material at the location of the electronic component. This localized modification allows light transmission where needed while maintaining normal display functionality in surrounding areas.
2Manufacturing precision
If pixel density is maintained in sub-pixel area corresponding to electronic component area, then display resolution is preserved, but light transmittance decreases
Solution Approach 1:
The patent extracts the pixel structure from the hole region where the electronic component is positioned. By removing pixels from this specific area and filling with transparent material, light transmittance is improved while the surrounding pixel structure maintains display resolution.

AI summary
An organic light emitting diode (OLED) display panel, a manufacturing method thereof, and an intelligent terminal are provided. The OLED display panel includes an electronic component area configured to position an electronic component and a sub-pixel area correspondingly disposed above the electronic component. The sub-pixel area includes a plurality of sub-pixels, and a first hole disposed on one of the sub-pixels is filled with a transparent material, which increases a screen-to-body ratio of the OLED display screen.
