Electronic device including non-flat display surface and image display method thereof

An electronic device having a non-flat display surface, comprising:

• a non-flat cover;
• a display device, disposed under the non-flat cover and comprising
• a display panel;
• and
• an image processing circuit, coupled to the display panel, and
• configured to group a plurality of edge display pixels in an edge display region of the display device into at least one pixel group according to a tilt state of an edge of the non-flat cover, wherein the display panel comprises the edge display pixels driven by the image processing circuit, and adjust image data according to a quantity of the at least one pixel group to drive the display panel to display according to the adjusted image data, wherein
• the edge display pixels in one of the at least one pixel group are configured to display a same image pixel of the adjusted image data,
• wherein the tilt state of the edge of the non-flat cover comprises a surface tilt angle respectively corresponding to each of the edge display pixels, and the edge display pixels comprise a first edge display pixel and a second edge display pixel, wherein
• when the surface tilt angle corresponding to the first edge display pixel satisfies a grouping condition, the first edge display pixel and the second edge display pixel adjacent to the first edge display pixel are grouped into the at least one pixel group, and
• when the surface tilt angle corresponding to the first edge display pixel does not satisfy the grouping condition, the first edge display pixel is not grouped with another edge display pixel.
