Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices with integrated photosensitive devices, such as cameras, suffer from image deformation due to differences in pixel unit shapes between transparent and non-transparent display regions, affecting full-screen display and user experience.
Innovation Solution
A display substrate with a first display region of higher light transmittance and a second display region of lower light transmittance, featuring OLED pixels arranged in a specific pattern to reduce diffraction and ensure similar pixel unit shapes, allowing for full-screen display without image deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a notch is provided in the display panel for accommodating cameras, earpieces and infrared sensing elements, then these components can be integrated, but the notch area cannot be used to display images
Solution Approach 1:
The patent extracts the photosensitive device from the traditional side-mounted position and relocates it to the rear of the display panel, allowing the front surface to be fully utilized for display purposes while maintaining camera functionality
Solution Approach 2:
The patent transitions from a planar integration approach (notch cutout) to a three-dimensional arrangement by placing the photosensitive device on the rear surface of the display panel, enabling full-frontal display coverage
2Adaptability or versatility
If a hole is provided on the screen for accommodating cameras, then the camera can be integrated, but external light may enter the photosensitive element via the hole causing image deformation
Solution Approach 1:
The patent removes the hole from the front display surface and relocates the camera module to the rear of the display panel, eliminating the source of light interference and image deformation
Solution Approach 2:
The display panel itself acts as an intermediary structure that houses the photosensitive device on its rear surface, allowing light to reach the sensor without passing through holes in the display surface
3Ease of manufacture
If different pixel unit shapes are used in transparent and non-transparent display regions, then the structural requirements can be met, but image deformation occurs
Solution Approach 1:
The patent applies different pixel configurations to different regions: the first display region uses pixel units with first electrode blocks arranged to achieve high transmittance, while the second display region uses pixel units with second electrode blocks arranged for normal display, with each region's pixel shape optimized for its specific function
Solution Approach 2:
The patent varies key parameters including electrode block arrangement, pixel unit shape, and light transmittance characteristics across different display regions to meet both structural requirements and display uniformity

AI summary
A display substrate and a display panel are provided. The display substrate includes: a substrate. The display substrate includes a first display region and a second display region. A light transmittance of the first display region is greater than a light transmittance of the second display region. The first display region is provided with a first pixel unit, and the second display region is provided with a second pixel unit, wherein a ratio of a first size of the first pixel unit in a first direction to a second size of the first pixel unit in a second direction is substantially same as a ratio of a first size of the second pixel unit in the first direction to a second size of the second pixel unit in the second direction, the first direction intersecting with the second direction.
