With the increasing demand of screen ratio of consumer products such as mobile terminals in the market, a transparent display area capable of being used for displaying and collecting images at the same time can be arranged on the display panel in order to improve the screen ratio. The transparent display area can realize normal display of pixels of the functional area, and if normal use of the functional piece is to be realized, high screen transmittance is required to ensure that enough external light enters the functional piece, so that photographing or fingerprint identification functions of the functional piece can be realized. In the prior art, the light utilization rate can be improved by adopting a COE (Color on Encapsulation) technology and adopting an ultrathin filter structure to replace a polaroid, the COE of conventional design is formed by patterning 4 different color organic glues, namely black organic glue, red organic glue, green organic glue and blue organic glue, and when external light enters a transparent display area, the light rays irradiate the black organic glue to be completely blocked; when the light irradiates the red organic glue, only red light can be allowed to pass through the red organic glue; when the light irradiates the green organic glue, only green light can be allowed to pass through the green organic glue; when light irradiates the blue organic glue, only blue light can be allowed to pass through the blue organic glue, and the light is seriously lost by superposition. Therefore, when the self-timer is started, a large part of external light is lost, and the sensing light quantity is insufficient to sense the starting to finish photographing.
However, if the organic glue of the COE layer corresponding to the transparent display area is simply removed, the light rays of the transparent display area are not filtered by the red organic glue, the green organic glue and the blue organic glue, so that the purity of the emitted light rays is not enough; the light rays of other display areas are more pure after being filtered by the red organic glue, the green organic glue and the blue organic glue, so that the display picture is more pure, and the display effects of the two areas are different, thereby causing the color cast problem.
The present invention has been made to solve the above-mentioned problems. In order to better understand the present invention, a display panel and a display device according to embodiments of the present invention are described in detail below with reference to fig. 1 to 3.
The inventor of the application finds that after the external light enters the film layer, the film layer can shield the incident light to a certain extent, and the quantity of the shielded light depends on the distance between the film layer and the substrate needing to transmit the light. The relationship between the blocked light and the spacing between the film and the substrate is as follows: the blocked light is the distance h between the film and the substrate, and the distance h is tan alpha, and the distance alpha is the angle of incidence of external light, so that the smaller the distance h between the film and the substrate is, the less the blocked light is. According to the embodiment of the invention, the shielding of external light is reduced by reducing the distance between the first filter unit of the first display area and the substrate, so that the light transmittance of the first display area is increased.
An embodiment of the first aspect of the present invention provides a display panel, where the display panel 1 includes a first display area 100 and a second display area 200 disposed adjacent to the first display area 100, the display panel 1 includes a substrate 10, a filter unit 70 is disposed on one side of the substrate 10, the filter unit 70 includes a first filter unit 71 located in the first display area 100, and a second filter unit 72 located in the second display area 200, the substrate 10 includes a first surface, and the first surface is a surface of the substrate 10 adjacent to the filter unit 70; in the thickness direction of the display panel, a distance between a side surface of the first filter unit 71 away from the substrate 10 and the first surface is smaller than a distance between a side surface of the second filter unit 72 away from the substrate 10 and the first surface. According to the embodiment of the invention, the shielding of external light is reduced by reducing the distance between the first filter unit of the first display area and the substrate, so that the light transmittance of the first display area is increased.
As shown in fig. 1, the first filter unit 71 and the second filter unit 72 are disposed to be offset from each other in the thickness direction of the display panel. The distance range between the first light filtering unit and the substrate is adjusted by arranging the first light filtering unit and the second light filtering unit of different layers, so that the first light filtering unit is closer to the substrate than the second light filtering unit, and the transmittance of the first display area is increased.
Specifically, in the present application, the second filter unit 72 of the second display area is located on the side of the encapsulation layer 50 away from the substrate 10, and the first filter unit of the first display area is disposed on the side of the encapsulation layer close to the substrate, so that the distance between the first filter unit 71 and the substrate 10 is smaller than the distance between the second filter unit 72 and the substrate 10, and the transmittance of the external light of the first display area can be increased.
The method is realized by the following scheme:
the display panel 1 comprises a light emitting layer 20, said light emitting layer 20 being located between said substrate 10 and said filter unit 70, said light emitting layer 20 comprising a first light emitting layer 21 located in said first display area 100 and a second light emitting layer 22 located in said second display area 200.
In the thickness direction of the display panel 1, the distance between the side surface of the first light filtering unit 71 away from the substrate 10 and the side surface of the first light emitting layer 21 away from the substrate 10 is smaller than the distance between the side surface of the second light filtering unit 72 away from the substrate 10 and the side surface of the second light emitting layer 22 away from the substrate 10. The first display area light transmittance is increased by setting the distance between the first light filtering unit and the first light emitting layer to be smaller than the distance between the second light filtering unit and the second light emitting layer. So that the less light the first display area is blocked when the external light is irradiated. The first filter unit 71 is located on a surface of the first light emitting layer 21 away from the substrate, so that the light emitted from the first light emitting layer is purer, and the color gamut of the first display area is enhanced while the external light transmittance of the first display area is increased.
As shown in fig. 2, in another embodiment of the present application, the display panel 1 includes a first electrode 30 and an encapsulation layer 50 on a side of the light emitting layer 20 away from the substrate 10; the first electrode 30 is located between the light emitting layer 20 and the encapsulation layer 50, and the first electrode 30 includes a first sub-electrode 31 located in the first display area 100 and a second sub-electrode 32 located in the second display area 200; the first filter unit 71 is located between the first light emitting layer 21 and the encapsulation layer 50, and the second filter unit 72 is located at a side of the encapsulation layer 50 away from the substrate. The first filter unit 71 is disposed on a surface of the encapsulation layer facing the first light emitting layer, so as to reduce the distance between the first filter unit 71 and the substrate 10, thereby reducing the light blocked by the first display area. Meanwhile, the first filter unit 71 is disposed on a side surface of the encapsulation layer facing the first light emitting layer, and can be coated with an organic adhesive on a side surface of the encapsulation layer facing the light emitting layer, and patterned, so that the process is simpler, the encapsulation layer is not easy to damage, and the encapsulation effect is affected. Preferably, the packaging layer is glass packaging or film packaging, if the packaging layer is glass packaging, the first filter unit can be formed by directly coating organic glue on the surface of the glass and then patterning, so that the packaging layer is not damaged; if the film is packaged, the first filter unit can be formed after the organic glue is prepared on the auxiliary substrate for patterning, and then the film packaging layer can be prepared after the auxiliary substrate is removed, so that the reliability of the packaging film layer can be effectively protected, and the intrusion of water and oxygen can be prevented.
Optionally, the first filter unit 71 is located between the first sub-electrode 31 and the encapsulation layer 50. Wherein the first filter unit 71 is located on a side surface of the first sub-electrode 31 away from the first light emitting layer 21. The closer the first filter unit 71 is to the first light emitting layer 21, the more external light is transmitted through the first display area.
As shown in fig. 3, in still other embodiments of the present application, the distance between the first filter unit and the substrate is smaller than the distance between the second filter unit and the substrate by reducing the thickness of the thin film layer in the first display area.

Preferably, the first filter unit 71 is located on a side surface of the first light emitting layer 21 away from the substrate, or the first filter unit 71 is located on a side surface of the first sub-electrode 31 away from the substrate, or the first filter unit 71 is located on a side surface of the first light extraction layer away from the substrate.

Specifically, the display panel further includes an array driving layer 11 and a second electrode stacked between the light emitting layer 20 and the substrate 10, and a first electrode 30, a light extraction layer 40, and an encapsulation layer 50 on a side of the light emitting layer 20 away from the substrate 10.
