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.

Display panel and display device using the same for wireless signal transmission

A display panel includes a substrate, a pixel structure, a receiver antenna structure and a transmitter antenna structure. The pixel structure includes multiple pixels arranged in an array. The receiver antenna structure provides first signals to the pixels, and includes multiple receiver antennas. The transmitter antenna structure transmits wireless signals to the receiver antenna structure such that the receiver antenna structure generates the first signals, and includes multiple transmitter antennas. Each transmitter antenna one-to-one corresponds to one receiver antenna. The transmitter and receiver antenna structures may be disposed on different sides of the substrate, and each receiver antenna may have a corresponding hole formed on the substrate for filling a ferrite structure to enhance transmission efficiency thereof. Alternatively, the transmitter and receiver antenna structures may be disposed on the same side of the substrate, thus reducing the distance between the transmitter and receiver antennas and enhance transmission efficiency thereof.

Wireless display scan line control

An active matrix display panel includes a pixel structure having multiple pixels arranged in an array, and a receiver antenna structure. The receiver antenna structure include multiple first receiver antennas having a greater size for providing power voltages to the pixels, and multiple second receiver antennas having a greater resonance frequency for providing data signals to the pixels. Each first receiver antenna and one or more second receiver antennas being surrounded by the first receiver antenna form a receiver antenna group. In the receiver antenna group, each second receiver antenna corresponds to multiple pixels. For each pixel, in a reset period, the pixel circuit controls a pixel capacitor to reset. In a data writing period, the pixel circuit controls the corresponding second receiver antenna to charge the pixel capacitor. In an emission period, the charged pixel capacitor controls the corresponding first receiver antenna to provide the power voltage.
