If mmWave module is integrated with display device, then device size is reduced, but interference from adjacent components increases
Solution Approach 1:
A phase tuning layer is introduced as an intermediary component between the mmWave module and the display device. This layer actively manages and adjusts the phase of electromagnetic waves passing through it, serving as a mediator that controls signal propagation while minimizing interference between the mmWave module and adjacent display components.
Solution Approach 2:
The phase tuning layer dynamically changes the phase parameter of electromagnetic waves by adjusting its electrical properties. By varying the phase shift according to control signals, the system optimizes signal transmission characteristics and reduces interference effects, allowing the mmWave module to operate effectively within the integrated display device.
2Object-affected harmful factors
If phase tuning layer is added to control signal propagation, then interference is minimized, but device complexity increases
Solution Approach 1:
The phase tuning layer is merged with the display device structure, integrating multiple functions into a unified component. This combination allows the phase tuning functionality to be implemented without adding separate, independent modules, thereby controlling device complexity while achieving interference minimization.
Solution Approach 2:
The phase tuning layer serves multiple functions simultaneously: it acts as an electromagnetic wave phase controller, an interference reduction mechanism, and an integral part of the display device structure. This multi-functionality reduces the need for additional dedicated components, thereby managing device complexity while achieving the desired interference mitigation.
