In this embodiment, the first pixels 1111, the second pixels 1211 and the sub light-transmitting portion 1221 have the same shape and size, the colors of the first pixels 1111 in the same column are the same, for example, the first pixels 1111 in the same column may be red pixels, green pixels or blue pixels, and the adjacent three columns of the first pixels 1111 include red pixels, green pixels and blue pixels, so that the first display portion 110 can display various colors.

Referring to fig. 5, in some embodiments, the first display portion 110 may include a first display panel 113, the first display panel 113 includes a first pixel portion 111, and the first pixel portion 111 is configured to emit first circularly polarized light as first polarized light; the second display section 120 includes a second display panel 123, and the second display panel 123 includes a second pixel section 121, and the second pixel section 121 is configured to emit second circularly polarized light as second polarized light. The first circularly polarized light and the second circularly polarized light have opposite rotation directions, for example, the first circularly polarized light is left circularly polarized light, and the second circularly polarized light is right circularly polarized light. Therefore, the first polarized light and the second polarized light with different polarization directions can be directly generated through the first pixel part 111 and the second pixel part 121, the structure is simple, and the size of the display screen 100 can be effectively reduced.

In this embodiment, the first display panel 113 and the second display panel 123 may be both OLED (Organic Light-Emitting Diode) display screens, and further, the first display panel 113 and the second display panel 123 may be both OLED display screens with RGB pixels Emitting Light independently. The OLED display screen comprises a high-molecular OLED luminescent material, wherein the high-molecular OLED luminescent material generally generates linearly polarized light, and when the light passes through a luminescent layer containing chiral molecules, the light can be changed into circularly polarized light, so that the OLED display screen can emit left-handed circularly polarized light, right-handed circularly polarized light, horizontal linearly polarized light, vertical linearly polarized light or unpolarized light and the like by changing the characteristics of the chiral molecules in the luminescent layer.

The second display panel 123 may also include a light emitting layer, a hole transport layer, an anode layer, and a substrate sequentially stacked on the light emitting side of the light emitting layer, and an electron transport layer, a cathode layer, and the like stacked on the other side of the light emitting layer. The light emitting layer of the second display panel 123 may include the second pixel part 121 and the light-transmitting part 122, that is, the second pixel part 121 and the light-transmitting part 122 constitute the light emitting layer of the OLED display screen, and the second pixel part 121 is used to emit second circularly polarized light. The hole transport layer, the anode layer, and the substrate are transparent, and the electron transport layer and the cathode layer are also transparent, light generated by the second pixel portion 121 is emitted outward through the hole transport layer, the anode layer, and the substrate, and light generated by the first display portion 110 is emitted outward through the cathode layer, the electron transport layer, the light-transmitting portion 122, the hole transport layer, the anode layer, and the substrate.

In some other embodiments, the first pixel portion 111 is configured to emit a first linearly polarized light as a first polarized light, and the second pixel portion 121 is configured to emit a second linearly polarized light as a second polarized light. The first linearly polarized light and the second linearly polarized light are perpendicular to each other, for example, the first linearly polarized light is a horizontal linearly polarized light, and the second linearly polarized light is a vertical linearly polarized light, so that the first polarized light and the second polarized light having different polarization directions can be generated in the first display part 110 and the second display part 120.

Further, the external natural light can transmit through the second display panel 123, the external natural light transmitted through the second display panel 123 is converted into horizontal linear polarized light through the second 1/4 phase retarder 116 and the horizontal line polarizing film 115, and then converted into right-handed circular polarized light through the first 1/4 phase retarder 114, when the right-handed circular polarized light irradiates the metal cathode layer or other metal substrate of the first display panel 113, the left-handed circular polarized light with the opposite direction generated by mirror reflection is emitted from the first display panel 113, and then converted into vertical linear polarized light through the first 1/4 phase retarder 114, and then absorbed by the horizontal line polarizing film 115, so that the influence of the external natural light (i.e., the ambient light) on the display effect of the display screen 100 can be eliminated.
