Abstract: A display panel includes a display module and an anti-glare layer. The display module has a pixel density PPI, and the display module includes an upper substrate. The anti-glare layer is over the display module. A top surface of the anti-glare layer has a plurality of microstructures, and the microstructures have a root mean square slope R?q. A thickness L from a bottom of the upper substrate of the display module to a top of the anti-glare layer complies with a following relational expression: L > 0.001 * PPI R ? ? ? q .

Abstract: In some examples, an electronic device comprises a wireless transceiver to transmit a packet and a processor coupled to the wireless transceiver. The processor is to update a running average of a radiation level over a time period. The running average is based on a quantity of packets transmitted by the wireless transceiver during the time period and a radiation level associated with the quantity of packets. The processor is to determine whether the running average exceeds a threshold and to control transmission power for the packet based on the determination and based on a destination of the packet.
