Gradual Pixel Density Transition in Micro LED Display Sensor Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The abrupt change in pixel density between normal display areas and areas with optical electronic elements in display panels leads to poor transition and display effects, as reducing pixel density in these areas results in visible boundaries and impaired transparency.
Innovation Solution
A display panel design featuring a first display area with micro light-emitting diode pixel units and a second display area with organic light-emitting diode pixel units, where the pixel density of the first display area gradually decreases, creating a smooth transition and increasing the light-transmitting area to enhance the display effect and usability of sensors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If pixel density is reduced in the area where optical electronic elements are disposed, then transparency of the area is improved, but pixel density changes abruptly between normal display area and the area where optical electronic elements are disposed, resulting in poor transition of display effect
Solution Approach 1:
The patent applies local quality by differentiating pixel density across different regions of the display panel. The normal display area maintains high pixel density for optimal display quality, while the sensor reserved area uses low pixel density to maximize light transmission. The transition area implements gradual pixel density reduction, creating a gradient that smoothly connects the two extreme regions. This spatial variation in pixel density quality resolves the contradiction between maintaining transparency in the sensor area and preserving display effect uniformity across the panel.
2Illumination intensity
If pixel density is reduced in the area where optical electronic elements are disposed, then light transmission is improved, but display effect is affected due to abrupt pixel density change
Solution Approach 1:
The patent implements dynamics by creating a gradient transition in pixel density rather than using fixed, abrupt boundaries. The pixel density dynamically changes from high in the normal display area through intermediate values in the transition area to low in the sensor reserved area. This dynamic variation in pixel density distribution allows the display panel to adaptively balance light transmission requirements in the sensor area with display quality requirements in the normal area, resolving the contradiction between these two opposing demands.
