Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The shapes and sizes of the various elements in the drawings are not to scale and are merely intended to facilitate an understanding of the contents of the embodiments of the invention.
As shown in fig. 2 and 3, wherein fig. 3 is a side sectional view of fig. 2 taken along the direction C-D. The present embodiment provides a display panel including a substrate 1, and a plurality of pixel units 01 disposed on the substrate 1, each pixel unit 01 being divisible into a display area a1 and a non-display area a2, the pixel unit 01 including a light emitting device 11 and a driving device 21 disposed over the substrate 1, and the light emitting device 11 being disposed corresponding to a position of the display area a1, the driving device 21 being disposed between the light emitting device 11 and the substrate 1, the driving device 21 being for driving the light emitting device 11 to emit light. The display panel may further include a light-shielding layer 12 and an anti-reflection layer 13.
Specifically, as shown in fig. 3, the light-shielding layer 12 is located on the side of the light-emitting device 11 away from the substrate 1, and the light-shielding layer 12 is disposed at a position corresponding to the non-display area a2 of the pixel unit, and the light-shielding layer 12 can prevent light below the non-display area a2 from being transmitted to the top. The position of the light shielding layer 12 corresponding to the display area a1 is a hollow structure, so that light emitted by the light emitting device 11 is transmitted. The anti-reflection layer 13 is disposed on a side of the light shielding layer 12 away from the light emitting device 11, the anti-reflection layer 13 is disposed at a position corresponding to the display area a1 of the pixel unit, and the anti-reflection layer 13 is configured to absorb external light reflected in the display area a1 of the pixel unit.
When the display panel is used, after external light is irradiated onto the display panel, the external light may be irradiated onto the light emitting devices 11 in the display area a1, and the light emitting devices 11 have electrodes, and the electrodes on the light emitting devices 11 may reflect the external light, thereby affecting the display effect of the display panel, such as reducing the contrast of the display panel, and especially if the display panel is used under strong light, the external light reflected in the display area a1 may cause "glare" on the display panel. In the display panel provided by this embodiment, the anti-reflection layer 13 is disposed in the display area a1 of the pixel unit, so that the anti-reflection layer 13 can absorb the external light reflected by the display area a1 in the display area a1, thereby preventing the display panel from reflecting light and improving the display effect of the display panel. Furthermore, light emitted from the light emitting device 11 may leak into the non-display area a2 of the pixel unit through reflection of structures inside the display panel, and the display panel provided in this embodiment can prevent light below the non-display area a2 from being transmitted to the top because the light shielding layer is disposed in the non-display area a2 of the pixel unit. By matching the anti-glare layer 13 with the light shielding layer 12, the luminance of the display area a1 of the pixel unit can be ensured, and the non-display area a2 of the pixel unit is ensured to be strictly light-tight, so that the display effect of the display panel can be improved, the contrast of the display panel is improved, and the display panel has an excellent black level.
Further, as shown in fig. 3, in the above display panel provided in the present embodiment, the anti-reflection layer 13 may include various types, for example, the anti-reflection layer 13 may be a Circular Polarizer (CPOL). The circular polarizer may include a quarter-wave retarder and a linear polarizer, which are stacked, the quarter-wave retarder being disposed at a side close to the light emitting device 11.

If external light is irradiated onto the display panel provided in this embodiment, after the external light passes through the linear polarizer in the CPOL on the display area a1, the first polarized light is changed into the first polarized light, after the first polarized light passes through the quarter-wave retarder under the linear polarizer in the CPOL, becomes circularly polarized light which is irradiated onto the light emitting device 11 in the display area a1, reflected by the light emitting device 11, passes through the quarter-wave retarder in CPOL again, becomes second polarized light, and the phase of the second polarized light is 90 degrees different from that of the first polarized light layer, so that the second polarized light can not be transmitted out through the linear polarizer in the CPOL, therefore, the CPOL disposed in the display area a1 corresponding to the pixel unit can prevent external light from reflecting on the display panel after being reflected by the light emitting device 11, which may affect the display effect of the display panel. Moreover, the light emitted by the light emitting device 11 in the display area a1 can normally transmit through the CPOL without affecting the light emitting effect of the light emitting device 11 in the display area a 1.

Wherein the APF 15 is arranged on the side of the anti-reflection layer 13 which is far away from the light shielding layer 12. On the side of the APF 15 close to the light emitting device 11, light emitted from the light emitting device 11 may be transmitted by the APF 15, and thus the display panel can normally display an image. On the side of the APF 15 away from the light emitting device 11, if the external light irradiates the display panel, the APF 15 reflects the external light, so that the display panel can have a mirror function.
