Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.

The technical scheme of the embodiment of the invention aims at the local non-uniform resolution display, and the display can allocate more pixels in a watching area (such as a middle attention area) of a user watching screen and allocate less pixels in other areas (such as an edge area) so as to achieve the purpose of reducing the cost of the display. In order to enable the common film source to be displayed normally on such a display, the resolution of the source end and the resolution of the screen need to be matched, and the ratio of the displayed image is ensured to be unchanged by performing image processing on the source end signal in a subarea manner.
