With the increasing demand for screen occupation ratio of consumer products such as mobile terminals in the market, in order to increase the screen occupation ratio, a transparent display area which can be used for displaying and collecting images at the same time can be arranged on the display panel. This transparent display area can realize the pixel normal display in functional area, if can realize the normal use of function piece, thereby needs high screen body transmissivity to guarantee enough external light and get into function piece department, just can realize shooing or the fingerprint identification function of function piece. In the prior art, a COE (color on encapsulation) technology is adopted, an ultrathin optical filter structure is adopted to replace a polarizer, so that the light utilization rate can be improved, the COE in the conventional design is made by patterning 4 organic glues with different colors, 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 is completely blocked when the external light irradiates the black organic glue; when light irradiates the red organic glue, only red light can be allowed to penetrate through the red organic glue; when light irradiates the green organic glue, only green light can be allowed to penetrate through the green organic glue; when light is irradiated to the blue organic glue, only blue light is allowed to pass through, and thus light loss due to superposition is severe. Therefore, when the self-timer is started, a large part of external light can be lost, and the sensing light quantity is not enough to sense the starting to finish the photographing.
If the COE layer organic glue corresponding to the transparent display area is simply removed, the purity of the light emitted by the transparent display area is insufficient because the light is not filtered by the red organic glue, the green organic glue and the blue organic glue; and the light that the light of other display areas filters through red organic glue, green organic glue, blue organic glue makes the display screen more pure more, and the display effect in two regions will have the difference like this, then can arouse the colour cast problem.
The present invention is proposed to solve the above-mentioned technical problems. For better understanding of the present invention, the display panel and the display device according to the embodiment 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 amount of the shielded light depends on the size of 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 shielded light is the distance h tan alpha between the film layer and the substrate, and alpha is the incident angle of the external light, so the smaller the distance h between the film layer and the substrate, the less the shielded light is. According to the embodiment of the invention, the distance between the first filtering unit of the first display area and the substrate is reduced to reduce the shielding of external light so as to increase the light transmittance of the first display area.
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 side surface of the substrate 10 close to the filter unit 70; in the thickness direction of the display panel, the distance between the first surface and the surface of the first filter unit 71 far away from the substrate 10 is smaller than the distance between the first surface and the surface of the second filter unit 72 far away from the substrate 10. According to the embodiment of the invention, the distance between the first filtering unit of the first display area and the substrate is reduced to reduce the shielding of external light so as to increase the light transmittance of the first display area.
As shown in fig. 1, the first filter unit 71 and the second filter unit 72 are arranged to be shifted 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 in 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 filtering unit 72 of the second display area is located on one side of the package layer 50 away from the substrate 10, and the first filtering unit of the first display area is disposed on one side of the package layer close to the substrate, so that the distance between the first filtering unit 71 and the substrate 10 is smaller than the distance between the second filtering unit 72 and the substrate 10, that is, 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 includes a light emitting layer 20, the light emitting layer 20 is located between the substrate 10 and the filter unit 70, and the light emitting layer 20 includes a first light emitting layer 21 located in the first display area 100 and a second light emitting layer 22 located in the second display area 200.
In the thickness direction of the display panel 1, the distance between the surface of the first filter unit 71 away from the substrate 10 and the surface of the first light-emitting layer 21 away from the substrate 10 is smaller than the distance between the surface of the second filter unit 72 away from the substrate 10 and the surface of the second light-emitting layer 22 away from the substrate 10. The light transmittance of the first display area 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 shielded from when the ambient 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 light emitted by the first light emitting layer is purer, and the color gamut of the first display area is enhanced while the ambient light transmittance of the first display area is increased.

The first filter unit 71 is disposed on a surface of the encapsulation layer facing the first light emitting layer to reduce a distance between the first filter unit 71 and the substrate 10, so as to reduce light blocked by the first display area. Meanwhile, the first filtering unit 71 is disposed on a side surface of the encapsulation layer facing the first light emitting layer, and the organic glue is coated on the side surface of the encapsulation layer facing the light emitting layer and patterned, so that the process is simpler, the encapsulation layer is not easily damaged, and the encapsulation effect is not easily affected. Preferably, the packaging layer is glass packaging or film packaging, and if the packaging layer is glass packaging, the surface of the glass can be directly coated with organic glue and then patterned to form a first filtering unit, so that the packaging layer cannot be damaged; if the film packaging is adopted, the organic glue is prepared on the auxiliary substrate firstly, the first light filtering unit is formed after the patterning, the auxiliary substrate is removed, and then the film packaging layer is prepared, so that the reliability of the packaging film layer can be effectively protected, and the invasion of water and oxygen can be prevented.

The first filter unit 71 is located on a surface of the first sub-electrode 31 away from the first light-emitting layer 21.
