Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the display device size is increased to achieve larger display resolution, then the display resolution is improved, but the voltage drop (IR drop) during signal transmission worsens
Solution Approach 1:
The display panel is divided into multiple block zones, with each zone having its own receiver antenna structure. This segmentation allows independent optimization of antenna parameters for different regions, enabling compensation for voltage drop in specific areas without affecting the entire display device.
Solution Approach 2:
Different receiver antennas in different block zones are designed with different winding numbers, outer diameters, and line thicknesses according to their specific positional requirements. This local quality approach ensures that each antenna is optimized for its specific location, compensating for IR drop variations across the large display device.
2Area of stationary object
If wireless transmission technology is used to eliminate peripheral non-display area, then the display area is increased, but the signal transmission distance increases causing severe voltage drop
Solution Approach 1:
The display panel is divided into multiple block zones, with each zone having its own receiver antenna structure. This segmentation allows independent optimization of antenna parameters for different regions, enabling compensation for voltage drop in specific areas without affecting the entire display device.
Solution Approach 2:
The antenna parameters (winding number, outer diameter, line thickness) are changed according to the positional requirements of different block zones. This parameter optimization compensates for the increased transmission distance in larger display devices, maintaining signal integrity while maximizing display area.

AI summary
A display panel includes a pixel structure corresponding to a display area, and a receiver antenna structure disposed on the pixel structure. The receiver antenna structure includes multiple receiver antennas providing first signals to the pixels of the pixel structure. Each receiver antenna corresponds to at least one pixel, and has an induced decibel (dB). For each receiver antenna, the induced dB is determined by multiple parameters of the receiver antenna, such as a winding number of the receiver antenna; an outer diameter of the receiver antenna; an inner diameter of the receiver antenna; a line pitch of the receiver antenna; a line width of the receiver antenna; and a line thickness of the receiver antenna. The induced dB of at least one of the receiver antennas is greater than the induced dB of other receiver antennas. The display panel may be used in a tiled micro LED display apparatus.
