The first region has a physical pixel density smaller than that of the second region. By providing a first region and a second region and having a greater physical pixel density in the second region than that in the first region, light can transmit through the gap between the pixels in the first region configured to house the under-screen photosensitive module such as a camera and the like, so as to achieve a high light transmittance and therefore to achieve an entire screen or full screen display. A non-display region above the active display region can be omitted and the screen-to-body ratio is increased, user experience is optimized and thus the technical problem of unfavorable user experience due to the presence of the non-display region is addressed.
