Display screen, display device integrated with display screen, and cover plate

A display terminal, comprising:

• a device body having a component area;
• and
• a display panel, comprising:
• a first display area;
• a display transition area having a plurality of display transition unit areas, the plurality of display transition unit areas including a first display transition unit area and a second display transition unit area and a third display transition unit area, the first display transition unit area being adjacent to the second display transition unit area, the first display transition unit area and the second display transition unit area being characterized by a first luminance difference of 3 nits, the third display transition unit area being adjacent to the second display transition unit area, the third display transition unit area and the second display transition unit area being characterized by a second luminance difference of 3 nits;
• and
• a second display area, a second type of the second display area being different from a first type of the first display area;
• wherein, the first display area and the second display area are disposed at two opposite sides of the display transition area respectively;
• in a direction from the first display area to the second display area, the display transition unit areas are sequentially arranged adjacent to one another;
• and
• in a full-screen display, a luminance of the first display area, a luminance of the display transition unit area and a luminance of the second display area change sequentially, and a luminance of the display transition unit areas is different;
• wherein the display panel is provided on the device body;
• wherein the component area is disposed below the second display area;
• wherein a photosensitive component is arranged in the component area;
• and
• wherein the photosensitive component receives light passing through the second display area.
