Abstract: An electronic device includes a host controller. The host controller splits a to-be-displayed image into at least two sub images, where each sub image and an adjacent sub image thereof include at least one column of overlapping image pixels. The host controller sends the at least two sub images to at least two display drive circuits, so that the at least two display drive circuits can jointly drive a display screen to display the to-be-displayed image in a sub pixel rendering (SPR) manner.

Abstract: This application provides a signal transmission method and apparatus. The method includes: A collaboration device receives a synchronization trigger frame delivered by a central device; the collaboration device obtains information about a time domain offset and/or information about a frequency domain offset; and the collaboration device sends a signal based on the synchronization trigger frame and the information about the time domain offset and/or the information about the frequency domain offset by using a corresponding time domain resource and a corresponding frequency domain resource. In this way, a plurality of collaboration devices send different time domain resources and/or frequency domain resources to a same terminal, and an interfering signal in channel estimation can be removed. This improves precision of the channel estimation and noise estimation at a receiving end, and improves demodulation performance at the receiving end and entire-network throughput.
