1Area of stationary object
If the optical module is placed under the display panel, then the screen ratio is improved and full screen display is achieved, but the light transmittance to the optical module is reduced
Solution Approach 1:
The display panel is divided into multiple regions: an optical module arrangement region with reduced pixel density for light transmission, and a first display area with normal pixel density for display functionality. This segmentation allows different areas to serve different purposes, optimizing both screen ratio and light transmittance.
Solution Approach 2:
The pixel density is locally adjusted in the optical module arrangement region, reducing it from the standard display density to a lower density that facilitates light transmission. This local modification enables the optical module to receive sufficient light while maintaining high display quality in other regions.
2Area of stationary object
If pixel circuits are relocated to the first display area, then the light transmission region area is increased, but the device complexity increases
Solution Approach 1:
The pixel circuits are relocated from the optical module arrangement region to the first display area, utilizing the spatial dimension of the display area to accommodate additional circuitry. This relocation increases the light transmission region area while managing complexity through structured spatial organization.
