Abstract: This application provides a security authentication method and apparatus applied to Wi-Fi, to help prevent a password from being shared among a plurality of devices, and implement management of a second device by a first device. In the method, an access point AP receives a first password input by the first device, where the first password is a password preset before delivery; and when checking on the first password by the AP succeeds, the AP obtains a second password shared between the AP and the first device, and performs 4-way handshake with the first device based on the second password. The second password is a shared key between the first device and the AP. Then, the AP can receive a first request from the first device, and send a third password to the first device in response to the first request, where the first request is used to request the second device to access the AP, and the third password is a shared key between the second device and the AP.

Abstract: A pixel structure is provided, where the pixel structure is used in a self-luminous display panel. The pixel structure includes: a plurality of subpixels. At least one subpixel in the plurality of subpixels includes a plurality of sub-subpixels, and a partition layer is arranged between two adjacent sub-subpixels. Light emission of the plurality of sub-subpixels is separately and independently controlled. In a case of a low display gray scale, density of a current flowing through a light emitting device is low, and only some sub-subpixels are controlled to emit light. Because a light emitting area of a sub-subpixel is smaller than a light emitting area of a subpixel, a current density of the sub-subpixel is greater than a current density of the subpixel. When the current density is large, stability of a light emitting spectrum is better, and color display is more accurate. In addition, because the current density is increased, impact of electric leakages on uneven display is reduced, and a problem of uneven display is greatly alleviated.
