The present invention provides display panels including, but not limited to, the following embodiments and combinations of the following embodiments.
In one embodiment, as shown in fig. 1 to 4, the display panel 100 includes: the first substrate set 10 and the second substrate set 20 disposed opposite to each other, and a liquid crystal layer 30 disposed between the first substrate set 10 and the second substrate set 20, where the second substrate set 20 is disposed on a light incident side and a light emergent side, the first substrate set 10 includes: a light absorbing layer 101 for absorbing light; the reflective layer is located on a side of the light absorbing layer 101 near the second substrate set 20, and the reflective layer includes at least one reflective portion 102, where each reflective portion 102 is concave in a first direction 01, and the first direction 01 is a direction in which the first substrate set 10 points to the second substrate set 20.
The first substrate set 10 may be a rigid substrate or a flexible substrate, the second substrate set 20 may be a rigid substrate or a flexible substrate, and the constituent materials of the first substrate set 10 and the constituent materials of the second substrate set 20 may be the same or different. The rigid substrate may be glass or silicon wafer, the constituent materials of the rigid substrate may include, but are not limited to, at least one of quartz powder, strontium carbonate, barium carbonate, boric acid, boric anhydride, aluminum oxide, calcium carbonate, barium nitrate, magnesium oxide, tin oxide, zinc oxide, the flexible substrate may be a polymer material substrate, a metal foil substrate, an ultrathin glass substrate, a polymer/inorganic substrate, or a polymer/organic/inorganic substrate, and the polymer material may include at least one of polyethylene, polypropylene, polystyrene, polyethylene terephthalate, polyethylene naphthalate, and polyimide. It should be noted that, for the display panel 100, the ambient light is directed to the side of the second substrate set 20 away from the first substrate set 10 to enter the display panel 100, and is reflected by the reflective layer, but not limited to, and then penetrates the second substrate set 20 to enter the outside, so that the light incident side and the light emergent side of the display panel 100 are both the sides of the second substrate set 20.
The material of the liquid crystal layer 30 may include, but is not limited to, polymer dispersed liquid crystal, polymer network liquid crystal, and other materials capable of changing between transparent state and scattering state under voltage control. Here, as shown in fig. 1 to 4, the liquid crystal layer 30 is illustrated by taking a case where the liquid crystal layer 30 includes a plurality of liquid crystal molecules 301, and the plurality of liquid crystal molecules 301 may deflect under the action of an electric field to change the transmittance of the liquid crystal layer 30 for light. Specifically, as shown in fig. 1 and 3, when the liquid crystal layer 30 is in a transparent state, incident light may pass through the plurality of liquid crystal molecules 301 along a straight line; as shown in fig. 2 and 4, when the liquid crystal layer 30 is in a scattering state, incident light may be reflected in different directions by the action of the plurality of liquid crystal molecules 301.
As can be understood, as shown in fig. 1 and 3, when the liquid crystal layer 30 is in a transparent state, the light absorbing layer 101 in the first substrate set 10 in the present embodiment can absorb external light to greatly reduce light emitted out of the display panel 100, so that the corresponding area of the display panel 100 is in a black state; further, in the embodiment, the reflective layer 101 is disposed on a side of the light absorbing layer 101 near the second substrate set 20, and since the plurality of reflective portions 102 in the reflective layer are concave in the first direction 01, as shown in fig. 2 and 4, when the liquid crystal layer 30 is in a scattering state, the reflective portions 102 have a relatively flat surface, and can receive the reflected light emitted to the light absorbing layer 101 after passing through the effect of the liquid crystal molecules 301, that is, the reflective portions 102 block between the corresponding reflected light and the light absorbing layer 101, so as to prevent the corresponding reflected light from being emitted to the light absorbing layer 101 to be absorbed, and reflect the reflected light to penetrate through the second substrate set 20, so as to improve the light output of the display panel 100, thereby improving the brightness of the display panel 100 and further improving the visibility of the display screen of the reflective display device.
It should be noted that, as shown in fig. 2 and fig. 4, when the liquid crystal layer 30 is in the scattering state, the reflective portions 102 reflect the reflected light and then emit the reflected light through the portions located above the two sides of the reflective portions 102 to penetrate the second substrate set 20, so that a predetermined distance may be left between at least one side of each reflective portion 102 and the corresponding side of the display panel 100, so that the light penetrates the second substrate set 20.
In an embodiment, the constituent material of the reflecting portion 102 includes at least one of a metal and a metal alloy. It will be appreciated that, in conjunction with the discussion above, the reflective portion 102 reflects the reflected light to penetrate the second substrate set 20, i.e., the reflective portion 102 may be made of a high reflectivity material, and the constituent materials of the reflective portion 102 may include, but are not limited to, aluminum, silver. Further, as shown in fig. 2 and 4, in the cross-sectional view, the edge shape of the reflecting portion 102 recessed in the first direction 01 may be, but is not limited to, trapezoid, arc, parabola, or other multi-segment line or curve having a light collecting effect. Further, in the cross-sectional view, the distance between both ends of the reflection part 102 and the degree of the recess of the reflection part 102 may be set according to the light output amount of the display panel 100.
In one embodiment, as shown in fig. 1 to 4, the first substrate set 10 further includes: the bearing layer is located at a side of the reflecting layer away from the second substrate set 20, a plurality of concave portions 03 are formed at a side of the bearing layer close to the second substrate set 20, the concave portions 03 and the reflecting portions 102 are in one-to-one correspondence, and each reflecting portion 102 is located in the corresponding concave portion 03.
It should be noted that, since the reflective portion 102 is concave in the first direction 01, the plurality of concave portions 03 may be disposed by disposing the supporting layer to form a plurality of concave portions 03 on a side of the supporting layer near the second substrate set 20 so as to support the plurality of concave portions 03, so as to improve stability of the plurality of concave portions 03. Further, on a side of the carrier layer near the second substrate set 20, two adjacent concave portions 03 may be formed as a plane perpendicular to the first direction, or two adjacent concave portions 03 may be formed as an uneven microstructure therebetween, so as to implement diffuse reflection. For the display panel 100, the carrier layer may be separately fabricated to carry the plurality of reflective portions 102, or a film layer having other functions may be multiplexed as the carrier layer to carry the plurality of reflective portions 102.
In one embodiment, as shown in fig. 1 to 4, the first substrate set 10 further includes: a first substrate 103 located on a side of the light absorbing layer 101 near the second substrate set 20; a first electrode layer 104 located on a side of the first substrate 103 near the second substrate set 20, the first electrode layer 104 including a plurality of first electrode portions; as shown in fig. 1 to 2, the carrier layer is a first insulating layer 105, and the first electrode layer 104 is located on a side of the first insulating layer 105 away from the second substrate set 20 or on a side of the first insulating layer 105 close to the second substrate set 20; alternatively, as shown in fig. 3 to 4, the carrier layer is the light absorbing layer 101, and the first electrode layer 104 is located on a side of the light absorbing layer 101 near the second substrate set 20.
In the present embodiment, the first substrate 103 may carry the first electrode layer 104 and other film layers, and the light absorbing layer 101 is located on a side of the first substrate 103 away from the second substrate set 20, i.e. the light absorbing layer 101 is the film layer farthest from the light emitting side in the display panel 100. It can be appreciated that when the liquid crystal layer 30 is in a transparent state, the light absorbing layer 101 can maximally absorb the external light incident to the display panel 100 to maximally reduce the light emitted from the display panel 100, so as to improve the proximity between the black frame and the pure black frame in the corresponding region of the display panel 100, and improve the contrast ratio of the display panel 100.
The display panel 100 may include a plurality of sub-pixels, and the plurality of first electrode portions may correspond to the plurality of sub-pixels one by one, and each of the first electrodes has a corresponding first voltage to control a deflection angle of the plurality of liquid crystal molecules 301 located above the first electrode, thereby controlling transmittance of the corresponding plurality of liquid crystal molecules 301 to light, so as to present a corresponding screen brightness. Further, the second substrate set 20 may further include a second electrode layer 201, where the second electrode layer 201 may be disposed entirely and have a second voltage, and in combination with the above discussion, a voltage difference between each first electrode and the second electrode layer 201 forms a corresponding pad length to control the deflection angle of the plurality of liquid crystal molecules 301 located above the first electrode, so as to control the transmittance of the corresponding plurality of liquid crystal molecules 301 for light, so as to present a corresponding brightness of the screen.
Specifically, as shown in fig. 1 to 2, the carrier layer is a first insulating layer 105, and here, the first electrode layer 104 is illustrated as being located on a side of the first insulating layer 105 away from the second substrate set 20. According to the above discussion, each first electrode has a corresponding first voltage, and the plurality of reflective portions 102 made of metal also has conductivity, and the embodiment can avoid the plurality of reflective portions 102 electrically connected to the plurality of first electrode portions to have voltages by disposing the first insulating layer 105 between the reflective layer and the first electrode layer, thereby avoiding the influence of the voltages on the reflective portions 102 on the deflection of the liquid crystal molecules 301. Similarly, when the first electrode layer 104 is located on the side of the first insulating layer 105 near the second substrate set 20, the plurality of first electrode portions in the first electrode layer 104 may be disposed in an insulating manner with the plurality of reflective portions 102, so as to avoid that the plurality of reflective portions 102 have voltages to affect the deflection of the liquid crystal molecules 301, for example, the first electrode portions may be located on a plane perpendicular to the first direction formed between two adjacent concave portions 03 in the carrier layer. The constituent material of the first insulating layer 105 may include, but is not limited to, silicon nitride and silicon oxide, for example, the first insulating layer 105 may be a single-layer film or a composite film formed of at least one of silicon nitride, silicon oxide and an oxide resin.
Specifically, as shown in fig. 3 to fig. 4, the carrier layer is a light absorbing layer 101, and the first electrode layer 104 is located on a side of the light absorbing layer 101 close to the second substrate set 20. According to the above discussion, the light absorbing layer 101 is used for absorbing light, and can be multiplexed to carry a plurality of reflecting portions 102; further, since the light absorbing layer 101 is located at the bottommost side of the display panel 100, the distance between the first electrode layer 104 and the second electrode layer 201 in the present embodiment is smaller, so that the electric field intensity between the two can be increased, and power consumption can be saved, and at the same time, the plurality of reflecting portions 102 are not disposed between the first electrode layer 104 and the second electrode layer 201, so that the interference to the electric field between the first electrode layer 104 and the second electrode layer 201 can be reduced.
In an embodiment, as shown in fig. 3 to 4, the carrier layer is the light absorbing layer 101, and the first substrate set 10 further includes: and a second insulating layer 106 located between the reflective layer and the first electrode layer 104, where the second insulating layer 106 includes a plurality of protruding portions 04, and the plurality of protruding portions 04 and the plurality of reflecting portions 102 are in one-to-one correspondence, and each reflecting portion 102 is located between a corresponding protruding portion 04 and a corresponding recessed portion 03.
It can be understood that, in this embodiment, each protrusion 04 and the corresponding recess 03 are disposed opposite to each other, so that the shape of the corresponding reflection portion 102 can be further fixed, the stability of the reflection portion 102 is improved, and further, the shape of each protrusion 04 can be complementary to the shape of the corresponding recess 03. Specifically, the second insulating layer 106 may be first fabricated to form the protruding portions 04, and then a corresponding reflecting portion 102 is formed on the surface of each protruding portion 04 to cover the protruding portion 04; of course, a corresponding reflection portion 102 may be formed on the surface of each recess portion 03 in the light absorbing layer 101 to cover the recess portion 03. The constituent materials of the second insulating layer 106 may be referred to above in relation to the first insulating layer 105.
In one embodiment, as shown in fig. 1 to 4, the second substrate set 20 includes: the light absorbing portions 202 are configured to absorb light, the light absorbing portions 202 are in one-to-one correspondence with the reflecting portions 102, and each light absorbing portion 202 is disposed opposite to the corresponding reflecting portion 102.
Specifically, as shown in fig. 1 and 3, when the liquid crystal layer 30 is in a transparent state, the incident light incident on the light absorbing portion 202 is absorbed by the light absorbing portion 202, most of the incident light incident outside the light absorbing portion 202 penetrates through the first substrate 103 and is absorbed by the light absorbing layer 101, and a small part of the incident light incident outside the light absorbing portion 202 is reflected after entering the reflecting portion 102, and the light collecting effect of the concave reflecting portion 102 on the light is combined, so that the distance d between the upper end of the reflecting portion 102 and the light absorbing portion 202 is further reasonably set, and the light reflected by the reflecting portion 102 is absorbed by the light absorbing portion 202. Therefore, when the liquid crystal layer 30 is in the transparent state, a large amount of incident light may be absorbed by the light absorbing portion 202 or the light absorbing layer 101, so that the corresponding region of the display panel 100 may be in the black state. The distance d between the upper end of the reflective portion 102 and the light absorbing portion 202 may be 1 micron to 1 millimeter.
Specifically, as shown in fig. 2 and fig. 4, when the liquid crystal layer 30 is in the scattering state, most of the incident light incident outside the light absorbing portion 202 is scattered in the liquid crystal layer 30, a part of the scattered light is reflected to penetrate through the second substrate set 20 to enter the outside, and another part of the scattered light is reflected after being incident on the reflecting portion 102, and then is scattered in the liquid crystal layer 30 to penetrate through the second substrate set 20 to enter the outside, so that the area corresponding to the display panel 100 is in a bright state.
It can be understood that the light absorbing layer 101 is matched with the plurality of concave reflecting portions 102, so that the light absorbing layer 101 absorbs the light which is not scattered by the liquid crystal layer 30 but directly penetrates the liquid crystal layer 30 in the transparent state to help the display panel 100 to display in the black state, and the plurality of reflecting portions 102 change the route of the light scattered by the liquid crystal layer 30 in the scattering state to avoid being absorbed by the light absorbing layer 101, but are injected into the second substrate group 20 to improve the light output, thereby improving the brightness of the display panel 100 and further improving the visibility of the display screen of the reflective display device.
In a top view, the area ratio of the light absorbing portions 202 or the reflecting portions 102 projected on the display panel 100 may be set according to the light output of the display panel 100, and may be set to 5% to 90%. Of course, the present invention can also be used for displaying a color screen of an LCD, and the light absorbing portions 202 and the reflective portions 102 corresponding to each other can be distributed in a plurality of gaps formed between the sub-pixels, so as to prevent the light of different colors from being mixed.
In an embodiment, as shown in fig. 1 to 4, the projection of at least one of the reflecting portions 102 on the second substrate set 20 is located inside or on the edge of the corresponding light absorbing portion 202. It should be noted that, in conjunction with the above discussion, when the liquid crystal layer 30 is in a transparent state, the light reflected after being incident on the reflective portion 102 needs to be absorbed by the light absorbing portion 202; therefore, in this embodiment, the size of the light absorbing portion 202 is set to be sufficiently large, for example, in the cross-sectional view, the size of the reflective portion 102 may be smaller than the size of the corresponding light absorbing portion 202 in the second direction 02, so that the light absorbing portion 202 covers the corresponding reflective portion 102, and in the case that the distance d between the upper end of the reflective portion 102 and the light absorbing portion 202 is constant, the corresponding area of the display panel 100 may be further facilitated to be in a black state, thereby improving the contrast of the display screen. Wherein the second direction 02 is perpendicular to the first direction 01.
In an embodiment, as shown in fig. 1 to 4, in the cross-sectional view, in the second direction 02, the absolute value of the difference between the dimension w1 of at least one of the reflective portions 102 and the dimension w2 of the corresponding light absorbing portion 202 is 4 micrometers to 4 millimeters. It should be noted that, in conjunction with the above discussion, although the light absorption portion 202 is required to absorb the light reflected after entering the reflective portion 102 when the liquid crystal layer 30 is in the transparent state, the light absorption portion 202 also absorbs the light reflected by the reflective portion 102 and/or scattered by the liquid crystal layer 30 when the liquid crystal layer 30 is in the scattering state, so as to reduce the light output; therefore, the size relationship between the reflective portion 102 and the corresponding light absorbing portion 202 is not limited in this embodiment, but the size difference between the reflective portion and the light absorbing portion is further limited, so that one of the reflective portion and the light absorbing portion is prevented from being too small or too large to seriously affect the black or bright image of the display panel 100.
In one embodiment, as shown in fig. 1 to 4, the second substrate set 20 further includes: a second substrate 203 located at a side of the plurality of light absorbing parts 202 away from the first substrate set 10; the second electrode layer 201 extends from between the second substrate 203 and the plurality of light-absorbing portions 202 to cover the second substrate 203, or from a side of the plurality of light-absorbing portions 202 away from the second substrate 203 to cover the second substrate 203. In connection with the above discussion, the second electrode layer 201 may be disposed entirely, specifically, in this embodiment, the second substrate 203 is disposed to carry the light absorbing portions 202 and the second electrode layer 201, where the relative positions of the light absorbing portions 202 and the second electrode layer 201 are not limited, and only the second electrode layer 201 needs to be entirely covered on the side of the second substrate 203 near the first electrode layer 104, so that the corresponding region has the corresponding electric field. Further, the side of the second substrate 203 away from the liquid crystal layer 30 may be provided with an anti-reflection coating or other transparent anti-dazzle coating to play a role in anti-reflection.
