Wireless Display Antenna Segmentation for Brightness Uniformity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless display devices often experience non-uniform brightness due to interference between data signals transmitted by adjacent antennas, leading to inconsistent illumination across the display panel.
Innovation Solution
The use of multiple receiving antenna units to provide phase-differentiated data signals to pixel units, allowing for controlled brightness adjustment across different areas of the display, maintaining an average brightness level by adjusting phase differences between signals during successive frames.

1Area of stationary object
If wireless transmission is used to transmit display data, then the display area can be increased and bezel area narrowed, but non-uniform brightness occurs
Solution Approach 1:
The display panel is divided into multiple areas (first area, second area, third area) that are respectively driven by different antenna units (first, second, third antenna units). Each antenna unit transmits data signals to its corresponding area through dedicated data lines, preventing signal interference between adjacent areas and ensuring uniform brightness across the entire display.
Solution Approach 2:
Different antenna units are assigned to drive different local areas of the display panel. The first antenna unit drives the first area, the second antenna unit drives the second area, and the third antenna unit drives the third area. This local assignment ensures that each area receives optimized signal transmission without interference from other areas, maintaining consistent brightness characteristics across the display.
2Illumination intensity
If multiple antenna units are used to drive different areas, then brightness uniformity can be improved, but device complexity increases
Solution Approach 1:
Multiple antenna units are designed with identical functional capabilities, each capable of independently driving a corresponding area of the display panel. This modular universal design allows the system to maintain brightness uniformity across multiple areas while keeping each antenna unit's structure standardized and manageable, reducing overall system complexity through repetition of proven functional blocks.
