The display panel disclosed in the present application will be specifically explained and illustrated with reference to fig. 1 to 16.
Fig. 1 is a schematic structural diagram of a display panel 100' provided in the related art. The display panel 100' includes a light emitting unit layer including a plurality of repeating units, each repeating unit including two or more light emitting units. The light emitting units may include a plurality of color light emitting units, such as a red light emitting unit 106', a green light emitting unit 108', and a blue light emitting unit 110'.
Referring to fig. 1, a display panel 100' includes a substrate 104' and a metal layer 102'. The metal layer 102' may be a metal layer in a driver circuit layer, a connection wire in a display panel, or the like, but the present invention is not limited thereto.
The inventor finds through experiments that when external ambient light enters the display panel, part of the external ambient light is reflected out of the display panel through one or more film layers (such as the metal layer 102' or other film layers) inside the display panel, the color of the reflected ambient light is different from that of light emitted by the light emitting unit, human eyes receive light of display light and the reflected ambient light at the same time, and the ambient light interferes with the displayed light to weaken the display effect.
In order to solve the above technical problem, the present application proposes a new display panel.
Referring to fig. 2 and 3, fig. 2 isbase:Sub>A schematic top view ofbase:Sub>A display panel provided in an embodiment of the present application, and fig. 3 isbase:Sub>A schematic cross-sectional view of the display panel provided in fig. 2 cut alongbase:Sub>A dotted linebase:Sub>A-base:Sub>A';
referring to fig. 2 and 3, the display panel 100 includes a substrate 104, and a light emitting cell layer is disposed on one side of the substrate 104. Further, an array layer or various metal wires may be further disposed on one side of the substrate.
In this embodiment, the substrate 104 may be made of PET (Polyethylene terephthalate, PET or PEIT, commonly called polyester resin, a condensation polymer of terephthalic acid and ethylene glycol), PMMA (poly (methyl methacrylate), PMMA), also called acryl, acryl or organic glass, PC (Polycarbonate, PC) is a high polymer containing carbonate in its molecular chain, PI (Polyimide), and the like. Further material types for the substrate 104 are not listed and described in detail herein, as would be understood by one of ordinary skill in the art.
The light emitting unit layer may include a plurality of repeating light emitting units, each of which may include light emitting units of one or more colors, such as a red light emitting unit, a green light emitting unit, a blue light emitting unit, and the like, and the three-primary color lights emitted from the red light emitting unit, the green light emitting unit, and the blue light emitting unit may be mixed with each other, so that the display panel may display a plurality of colors. The Light Emitting unit may include a Micro-LED (Micro Light Emitting Diode), a Mini-LED (Micro Light Emitting Diode), or an OLED (organic Light Emitting Diode).
In one embodiment of the present application, the repeating light emitting unit includes a first color light emitting unit 106. Illustratively, the first color light emitting unit 106 may include a red light emitting unit.
The display panel 100 further includes a first color filter layer 112 disposed on a side of the light emitting unit layer close to the substrate 104. Specifically, the first color filter layer 112 may include a red filter layer. It should be noted that, the first color light emitting units in fig. 2 and 3 are the same as the corresponding first color filter filling patterns, and are only used for identifying that the filter color of the first color filter is the same as the light emitting color of the first color light emitting units, and they are not substantially the same.
Further, in a direction perpendicular to the plane of the display panel, the first color filter layer 112 at least partially overlaps with an orthographic projection of the first color light emitting unit 106 on the substrate.
In the present application, in a direction perpendicular to a plane of the display panel, the first color filter layer 112 at least partially overlaps an orthographic projection of the first color light-emitting unit 106 on the substrate 104, and the first color filter layer 112 is located on a side of the first color light-emitting unit 106 close to the substrate. When the film on the substrate 104 reflects incident ambient light to the outside of the display panel (light-emitting side of the display panel), the reflected ambient light passing through the first color light-emitting unit 106 is first filtered by the first color filter layer 112, and the color of the filtered ambient light is changed into a first color, that is, the color of the filtered ambient light is the same as or similar to the color of the light emitted by the first color light-emitting unit 106, and the filtered ambient light cannot interfere with the light of the first color light-emitting unit 106, so that the display effect is improved.

Fig. 6 is a schematic structural diagram of a driving circuit of a display panel according to another embodiment of the present disclosure. Fig. 7 is a schematic structural diagram of a display panel according to another embodiment of the present application. Fig. 8 is a schematic structural diagram of a display panel according to another embodiment of the present application. Fig. 9 is a schematic structural diagram of a display panel according to another embodiment of the present application. Fig. 10 is a schematic structural diagram of a display panel according to another embodiment of the present application.
Referring to fig. 4, unlike the display panel shown in fig. 3, the display panel 100 further includes a driving circuit layer 102 disposed on one side of the substrate 104, and the driving circuit layer 102 is used for driving the light emitting units of the respective colors to emit light.
With continued reference to FIG. 4, the display panel further includes a first light reflecting layer 118, the first light reflecting layer 118 for reflecting incident ambient light away from the display panel. The first light reflecting layer 118 may be a metal reflecting layer or other materials with good light reflecting properties, and the metal coating of the metal reflecting layer may be silver (Ag), aluminum (Al), or platinum (Pt) with stable optical properties and high reflectivity.
Specifically, the first light reflecting layer 118 may be disposed between the first color filter layer 112 and the driving circuit layer 102. The inventors have found that when the active layer in the driver circuit layer 102 is irradiated with light, ions are likely to migrate, and the driver circuit becomes unstable during operation. In the present application, the first light reflective layer 118 is disposed between the first color filter layer 112 and the driving circuit layer 102, so that the driving circuit layer on the substrate 104 can be directly prevented from being directly irradiated by the ambient light, thereby improving the stability of the display panel.
Referring to fig. 5, fig. 5 is a schematic structural diagram of a display panel according to another embodiment of the present disclosure. Fig. 6 is a schematic structural diagram of a driving circuit in the display panel provided in fig. 5.
In the embodiment shown in fig. 5, the first light reflecting layer 118 may be disposed between the film layers of the driving circuit layer. As shown in fig. 5 and 6, the driving circuit layer 102 includes a plurality of film layers. The driving circuit layer may include an active layer 1020, a gate metal layer 1026, a source drain metal layer 1022 (1024), and the like. For example, the first light reflective layer 118 may be disposed between the active layer 1020 and the source/drain metal layer 1022, and in a direction perpendicular to the plane of the display panel, the first light reflective layer 118 at least partially overlaps the first color filter layer 112. It can be understood that, the multiple metal layers in the driving circuit layer generally have a strong reflection capability, and the first light reflection layer can cooperate with the metal film layer inside the driving circuit layer, so that the first light reflection layer and the metal film layer reflect ambient light together.
It will be appreciated that in this embodiment, part of the metal layers in the driver circuit layer are multiplexed into the first light reflecting layer, i.e. the first light reflecting layer 118 is used to reflect ambient light together with the metal film inside the driver circuit layer, which has the following advantages: the requirement of reflecting ambient light is met, and meanwhile, a first light reflecting layer with an overlarge area is not required to be arranged, so that the process cost is reduced.
Referring to fig. 7, a schematic structural diagram of a display panel according to another embodiment of the present disclosure is shown. In this embodiment, the first light reflecting layer 118 may also be disposed on a side of the substrate 104 away from the first color filter layer 112. Since the first reflector layer 118 generally comprises a metal material, when disposed on the side of the substrate 104 away from the first color filter layer 112, the first reflector layer can avoid the parasitic capacitance generated by the too close distance between the first reflector layer and the driving circuit layer on the substrate, which affects the operation of the driving circuit layer.
Referring to fig. 8, a schematic structural diagram of a display panel according to another embodiment of the present application is provided. In this embodiment, first light reflecting layer 118 may also be disposed between substrate 104 and driving circuit layer 102. The first light reflecting layer is generally made of a metal material, in this embodiment, the first light reflecting layer 118 may be further disposed between the substrate 104 and the driving circuit layer, and the first light reflecting layer 118 may serve as an electrostatic shielding layer for shielding static electricity on the substrate side. In addition, the first light reflecting layer 118 can also be used to conduct away static electricity generated by the driving circuit. In addition, when the first light reflecting layer is disposed on a side of the substrate 102 close to the light emitting unit layer, the substrate 102 can better protect the first light reflecting layer 118, and prevent the first light reflecting layer 118 from being damaged and affecting the reflection effect.
Referring to fig. 9, a schematic structural diagram of a display panel according to another embodiment of the present disclosure is shown.
To further improve the efficiency of the first light reflecting layer 118 in reflecting ambient light, a plurality of grooves may be disposed on the first light reflecting layer 118. As shown in fig. 9, a plurality of curved grooves 126 may be disposed in the first light reflecting layer 118, and in a direction perpendicular to the plane of the display panel, the first color light emitting unit 106 at least partially overlaps with an orthographic projection of the grooves 126 on the substrate 104. It can be understood that the groove 126 can collect the light incident to the groove 126 and adjust the emitting angle thereof, so that the ambient light can be emitted from the filter layer as much as possible, and the influence of the ambient light on the light of the first color light emitting unit can be better avoided.
With continued reference to fig. 7, each light emitting cell further includes a binding terminal 130, and the binding terminal 130 is used to bind the light emitting cell to the driving circuit layer 102. The binding terminal 130 may be inserted in the first color filter layer 112 to connect the light emitting unit and the driving circuit layer 102 on the substrate 102 to each other. Specifically, an opening may be provided when forming the first color filter layer 112, the opening penetrating the entire first color filter layer 112, and then the binding terminal 130 may be formed in the opening. Further, referring to fig. 4, one end of the binding terminal 130 is connected to the driving circuit layer 102, and the other end of the binding terminal 130 is connected to the light emitting unit, so that the light emitting unit is electrically connected to the driving circuit.
With continued reference to fig. 2-9, the repeating light-emitting units further include a second color light-emitting unit 108 and a third color light-emitting unit 110. Illustratively, the second color light emitting unit 108 may include a green light emitting unit, and the second color light emitting unit 108 may include a blue light emitting unit.
Further, the display panel further includes a second color filter layer 114 and a third color filter layer 116. Alternatively, the second color filter layer 114 and the third color filter layer 116 may be provided on the same layer as the first color filter layer 112.
In one example of the present application, the second color light emitting unit 108 at least partially overlaps with an orthographic projection of the second color filter layer 114 on the substrate 104, and the second color filter layer 114 is located on a side of the second color light emitting unit 108 close to the substrate 104. When the film on the substrate reflects incident ambient light to the outside of the display panel (light-emitting side of the display panel), the reflected ambient light passing through the second color light-emitting unit 108 is filtered by the second color filter layer 114, and the color of the filtered ambient light is changed into a second color, that is, the color of the filtered ambient light is the same as or similar to the color of the light emitted by the second color light-emitting unit 108, and the filtered ambient light cannot interfere with the light of the second color light-emitting unit 108, so that the display effect is improved.
In one example of the present application, the third color light emitting unit 110 at least partially overlaps with an orthographic projection of the third color filter layer 116 on the substrate 104, and the third color filter layer 116 is located on a side of the third color light emitting unit 110 close to the substrate 104. When the film on the substrate reflects incident ambient light to the outside of the display panel (light-emitting side of the display panel), the reflected ambient light passing through the third color light-emitting unit 110 is filtered by the third color filter layer 116, and the color of the filtered ambient light is changed to a third color, that is, the color of the filtered ambient light is the same as or similar to the color of the light emitted by the third color light-emitting unit 110, and the filtered ambient light cannot interfere with the light of the third color light-emitting unit 110, so that the display effect is improved.
Referring to fig. 10, a schematic structural diagram of a display panel according to another embodiment of the present application is provided.
Referring to fig. 10, fig. 10 is a schematic structural diagram of a display panel according to another embodiment of the present disclosure. Unlike the display panel shown in fig. 4, the filter layers corresponding to the light emitting units of the respective colors may be disposed on both sides of the binding terminals 130 of the light emitting units on the premise that the filter layers at least partially overlap with the orthographic projections of the light emitting units on the substrate 104.
Specifically, as shown in fig. 10, the first color filter layer 112 includes a first sub-filter layer 1122 and a second sub-filter layer 1124, and the first sub-filter layer 1122 and the second sub-filter layer 1124 are disposed at two sides of the bonding terminal 130 of the first color light emitting unit 106. Specifically, the first sub-filter layer 1122 is disposed on a side of the binding terminal of the first color light emitting unit 106 away from the second color light emitting unit 108. When the filter layer is disposed on both sides of the binding terminal 130, the contact area of the binding terminal 130 with the driving circuit layer is larger, and the stability of welding the binding terminal 130 with the driving circuit layer 102 can be further increased.
Fig. 11 is a schematic structural diagram of a display panel provided in another embodiment of the present application.
Referring to fig. 11, a retaining wall 150 is further disposed between each light emitting unit of the display panel, and the retaining wall 150 is used for shielding light of the light emitting units, so as to prevent color crosstalk between adjacent light emitting units from affecting the display effect.
Further, the retaining wall 150 may be located between different color filter layers in the present application. For example, referring to fig. 11, the dam 150 may be disposed between the first color filter layer 112 and the second color filter layer 114, or the dam 150 may be disposed between the third color filter layer 116 and the second color filter layer 114.
In an embodiment of the present application, the retaining wall 150 may be made of a reflective material, so that when the light of the light emitting unit is incident on the retaining wall 150, the retaining wall 150 may reflect the light out of the display panel, thereby improving the display brightness and the display effect.
In another embodiment of the present application, filter layers are further disposed on both sides of the retaining wall 150 to filter the ambient light more completely. Fig. 12 is a schematic structural diagram of a display panel provided in another embodiment of the present application. As shown in fig. 12, the first filter layer 1502 and the second filter layer 1504 are disposed on both sides of the wall 150 between the first color filter layer 112 and the second color filter layer 114, respectively. The third filter layer 1506 and the second filter layer 1508 are disposed on both sides of the wall 150 between the third color filter layer 116 and the second color filter layer 114, respectively. The first filter layer 1502 is located on a side of the second filter layer 1504 away from the second color light emitting unit 108, and the fourth filter layer 1508 is located on a side of the third filter layer 1506 away from the second color light emitting unit 108. The color of the second filter layer 1504 and the color of the third filter layer 1506 may both be the second color. The color of the first filter layer 1502 is a first color and the color of the fourth filter layer 1508 is a third color.
This application still sets up the filter layer through keeping off wall 150 both sides, can guarantee that the ambient light of incidenting is filtered by the filter layer as far as possible to avoid ambient light to influence the display effect better.
In another embodiment of the present application, the filter layers on both sides of the dam 150 and the filter layer under the light emitting unit may be integrally formed. As shown in fig. 13, the first color filter layer 112 is provided integrally with the first filter layer 1502, and the second color filter layer 114 is integrally formed with the second filter layer 1504 and the third filter layer 15046. Thus, the filter layer can be better ensured to filter the ambient light.
