As illustrated in FIG. 1, an OLED screen 100 can include a glass cover 110 and a display panel 130 adhered and connected by an optical glue layer 120. The OLED screen 100 also includes an auxiliary material 140 on a side of the display panel 130 away from the glass cover 110. The auxiliary material 140 has a light-transparent hole 150, and an optical sensor 160 is arranged at a side of the auxiliary material 140 away from the glass cover 110. The optical sensor 160 and the light-transparent hole 150 are arranged correspondingly. The side of the display panel 130 of the OLED screen 100 away from the glass cover 110 is divided into two regions, namely a first region 170 and a second region 180. The first region 170 is a region of the display panel 130 corresponding to a region of the auxiliary material 140 provided with the light-transparent hole 150, and the reflective material is not provided at the first region 170. The second region 180 is another region of the display panel 130 corresponding to another region of the auxiliary material 140 not provided with the light transparent hole 150, and a reflective layer formed by the reflective material (not illustrated in the drawings) is provided at the second region 180. When the OLED screen 100 is in sunlight, since the first region 170 is not provided with the reflective material, the first region 170 cannot reflect the ambient light incident on the OLED screen 100 from the external environment, and thus the dark spot is formed at the first region 170.
