The embodiment of the application provides a display panel and a display device.

As shown in fig. 1, the display panel provided in the embodiment of the present disclosure includes a first substrate 10, a second substrate 20, and a light valve medium layer 30, wherein the first substrate 10 and the second substrate 20 are disposed opposite to each other, and the light valve medium layer 30 is located between the first substrate 10 and the second substrate 20.
The light valve medium layer 30 can control whether external light can pass through the display panel by adjusting the propagation direction of the light, for example, the light valve medium layer 30 may specifically be a liquid crystal layer including liquid crystal molecules, and of course, the light valve medium layer 30 may also be other light valve medium materials.
In addition, the display panel provided by the embodiment of the present application further includes a heating electrode layer and a pixel electrode layer 12, and the display panel further includes a common electrode layer 14, where the heating electrode layer, the pixel electrode layer 12 and the common electrode layer 14 are located between the first substrate 10 and the second substrate 20. The heating electrode layer may be provided in the same layer as the pixel electrode layer 12 and/or the common electrode layer 14, in the same layer as another conductive layer, or in a single layer.
Referring to fig. 1 and fig. 2, fig. 3, fig. 4, and fig. 5, respectively, the heating electrode layer includes a plurality of heating electrodes 11, and the heating electrodes 11 are arranged along a first direction X in a plane perpendicular to a thickness direction of the display panel. It should be noted that the heating electrode 11 is disposed between adjacent sub-pixels, which are arranged along the first direction X in the display region of the display panel and a plurality of heating electrodes 11 may be electrically connected in the non-display region of the display panel.
The pixel electrode layer 12 includes a plurality of first pixel electrodes 121, a plurality of second pixel electrodes 122, and a plurality of third pixel electrodes 123, wherein the first pixel electrodes 121, the second pixel electrodes 122, and the third pixel electrodes 123 are respectively disposed corresponding to a sub-pixel.
The first pixel electrode 121, the second pixel electrode 122 and the third pixel electrode 123 can respectively control the adjustment effect of the light valve medium material in the corresponding sub-pixel on the propagation direction of the light. The heating electrode 11 may generate heat to change the characteristics of the nearby light valve dielectric material, so that the portion of the light valve dielectric material in the light valve dielectric layer 30 reacts rapidly under the control of the electrical signal. For example, the light valve medium layer 30 is specifically a liquid crystal molecule layer, when the heating electrode 11 is heated, the viscosity of the liquid crystal molecules may be reduced, so that the response speed of the liquid crystal molecules under the action of the electric field between the first pixel electrode 121, the second pixel electrode 122, the third pixel electrode 123 and the common electrode layer 14 is improved.
With reference to fig. 1 and fig. 2, fig. 3, fig. 4, and fig. 5, in a plane perpendicular to the thickness direction of the display panel, at least one of the first pixel electrode 121 and the second pixel electrode 123 is included between the third pixel electrode 123 and the adjacent heating electrode 11 along the first direction X. That is, the third pixel electrode 123 is not directly adjacent to the heating electrode 11 in the first direction X, and the first pixel electrode 121 and/or the second pixel electrode 123 are disposed therebetween. For example, as shown in fig. 1 to 5, the heating electrode 11 is located between the adjacent first and second pixel electrodes 121 and 122, but is not adjacent to the third pixel electrode 123, along the first direction X.
In an embodiment of the present application, referring to fig. 2-5, each of the first pixel electrode 121, the second pixel electrode 122, and the third pixel electrode 123 includes at least one branch electrode 12 a. The branch electrode 12a included in the first pixel electrode 121 is specifically a first branch electrode 121a, the branch electrode 12a included in the second pixel electrode 122 is specifically a second branch electrode 122a, and the branch electrode 12a included in the third pixel electrode 123 is specifically a third branch electrode 123 a.
In the embodiment of the present application, the branch electrodes 12a included in the first pixel electrode 121, the second pixel electrode 122 and the third pixel electrode 123 extend substantially along a second direction, the second direction is perpendicular to the first direction X, and the second direction is substantially parallel to the alignment angle of the liquid crystal molecules.
And when at least one of the first pixel electrode 121, the second pixel electrode 122 and the third pixel electrode 123 includes a plurality of branch electrodes 12a, the plurality of branch electrodes 12a are arranged along the first direction X and are electrically connected through the connection electrode 12 b. The connection electrode 12b included in the first pixel electrode 121 is specifically a first connection electrode 121b, the connection electrode 12b included in the second pixel electrode 122 is specifically a second connection electrode 122b, and the connection electrode 12b included in the third pixel electrode 123 is specifically a third connection electrode 123 b.
Further, an angle between the extending direction of at least one of the branch electrodes 12a in the third pixel electrode 123 and the first direction X is a first angle α, 89 ° < α ≦ 90 ° or 75 ° < α < 84 °. That is, an angle between the extending direction of at least one third sub-electrode 123a in the third pixel electrode 123 and the first direction X is a first angle α, 89 ° < α ≦ 90 ° or 75 ° < α < 84 °.
In one specific implementation, as shown in FIGS. 2 and 3, a first angle α between the extending direction of at least one of the branch electrodes 12a in the third pixel electrode 123 and the first direction X satisfies 89 ° < α ≦ 90 °. For example, as illustrated in FIG. 2, a first angle α between the extending direction of each of the two third branch electrodes 123a in the third pixel electrode 123 and the first direction X satisfies 89 ° < α ≦ 90 °; for example, as illustrated in FIG. 3, a first angle α between the extending direction of one third sub-electrode 123a in the third pixel electrode 123 and the first direction X satisfies 89 ° < α ≦ 90 °.
In another specific implementation, as shown in fig. 4 and 5, a first included angle α between at least one of the branch electrodes 12a in the third pixel electrode 123 and the first direction X satisfies 75 ° ≦ α < 84 °. For example, as illustrated in fig. 4, a first angle α between the extending directions of both the third branch electrodes 123a in the third pixel electrodes 123 and the first direction X satisfies 75 ° ≦ α < 84 °; for example, as illustrated in fig. 5, a first angle α between the extending direction of one third sub-electrode 123a of the third pixel electrodes 123 and the first direction X satisfies 75 ° ≦ α < 84 °.
The inventor finds that the reason why the display panel with the built-in heating electrode has the display unevenness is mainly that when the heating electrode is operated, the response speed of the liquid crystal molecules corresponding to the sub-pixel close to the heating electrode is high, and the response speed of the liquid crystal molecules corresponding to the sub-pixel far from the heating electrode is low.
In the present embodiment, the response speed of the light valve dielectric material included in the area where the third pixel electrode 123 is located can be improved by setting the angle between the extending direction of at least one of the branch electrodes 12a in the third pixel electrode 123 away from the heater electrode 11 and the first direction X to be in the range of 75 ° ≦ α < 84 ° or 89 ° < α ≦ 90 °.
In a low-temperature environment, the light valve medium material included in the area where the first pixel electrode 121 and the second pixel electrode 122 close to the heating electrode 11 are located may obtain a faster response speed when the heating electrode 11 is heated, and the light valve medium material included in the area where the third pixel electrode 123 far away from the heating electrode 11 obtains a faster response speed through the change of the electric field direction caused by the adjustment of the extending direction of the middle branch electrode 12a of the third pixel electrode 123. Therefore, the display panel provided by the embodiment of the application can realize that the response speeds of the light valve medium materials corresponding to the sub-pixels are basically consistent under the low-temperature environment, and further ensures the uniformity of the display brightness of each position of the display panel.
In one embodiment of the present application, as shown in fig. 2 to 5, the first pixel electrode 121 and the second pixel electrode 122 are adjacent to the heating electrode 11 in the first direction X, and an angle between the branch electrode 12a in the first pixel electrode 121 and the first direction X is a second angle β and 84 ° β ≦ 89 °; the included angle between the branch electrode 12a in the second pixel electrode 122 and the first direction X is a third included angle γ, and γ is greater than or equal to 84 ° and less than or equal to 89 °.
In the present embodiment, the extending direction of the sub-electrodes 12a in the first pixel electrode 121 and the second pixel electrode 122 ensures a high light transmittance in the region where the sub-pixels corresponding to the sub-electrodes are located.
In an embodiment of the present disclosure, the display panel further includes a color filter array layer 21 located between the first substrate 10 and the second substrate 20, where the color filter array layer includes a first color resistor 211, a second color resistor 212, and a third color resistor 213. The first color resistor 211, the second color resistor 212 and the third color resistor 213 are respectively disposed corresponding to the first pixel electrode 121, the second pixel electrode 122 and the third pixel electrode 123. That is, the sub-pixels corresponding to the first pixel electrode 121 and the first color resistor 211 are the first color sub-pixels, the sub-pixels corresponding to the second pixel electrode 122 and the second color resistor 212 are the second color sub-pixels, and the sub-pixels corresponding to the third pixel electrode 123 and the third color resistor 213 are the third color sub-pixels.
Also in the present embodiment, the light transmittance of the third color resistor 213 is smaller than the light transmittance of at least one of the first color resistor 211 and the second color resistor 212.
In the embodiment of the present application, the first included angle α is different from the second included angle β and/or the third included angle γ, so that the light transmittance of the sub-pixel to which the third pixel electrode 123 belongs is smaller than the light transmittance of the sub-pixel to which the first pixel electrode 121 and/or the second pixel electrode belongs. On the other hand, since the third color resist 213 itself has a small light transmittance, the reduction of the transmittance caused by changing the extending direction of the sub-electrode 12a in the third pixel electrode 123 has a small influence on the white balance of the display panel.
In an implementation manner of this embodiment, the third color resistor 213 is specifically a blue color resistor, the first color resistor 211 is one of a red color resistor and a green color resistor, and the second color resistor 212 is one of a red color resistor and a green color resistor. That is, the extending direction of the partial branch electrodes 12a in the pixel electrode corresponding to the blue color resistance and the first direction X form a first included angle α.
Since the blue color resistance is the lowest light transmittance of the three color resistances, the extending direction of part of the branch electrodes 12a of the pixel electrodes corresponding to the blue color resistance is changed, and the influence on the white balance of the display panel is the least.
In another implementation manner of this embodiment, the third color resistor 213 is specifically a red resistor, the first color resistor 211 is one of a blue resistor and a green resistor, and the second color resistor 212 is the other of the blue resistor and the green resistor. That is, the extending direction of the partial branch electrode 12a in the pixel electrode corresponding to the red color resistance and the first direction X form a first included angle α.
Since the light transmittance of the red color resist is smaller than that of the green color resist, changing the extending direction of part of the sub-electrodes 12a in the pixel electrodes corresponding to the red color resist has less influence on the white balance of the display panel.
In an embodiment of the present application, referring to fig. 2 and fig. 3, the third pixel electrode 123 includes at least three branch electrodes 12a arranged along the first direction X, that is, the third pixel electrode 123 includes at least three third branch electrodes 123 a.
