Detailed Description
In the related art, the display panel may include a first substrate and a second substrate that are disposed opposite to each other, wherein a supporting member is disposed between the first substrate and the second substrate, one end of the supporting member is connected to the first substrate, and the other end of the supporting member is connected to the second substrate. The first substrate can be provided with a light-emitting unit, and the support piece is used for supporting the second substrate so as to prevent the second substrate from extruding the light-emitting unit under the action of gravity and atmospheric pressure and prevent the light-emitting unit from being damaged.
Although the second substrate does not press the light emitting units under the supporting effect of the supporting member, the supporting member still deforms greatly under the action of the gravity of the first substrate and the second substrate and the atmospheric pressure, so that the distances between different positions of the first substrate and the second substrate are different. In addition, because the edge between the first substrate and the second substrate is provided with the sealing member, the sealing member can also form support for the second substrate, so that the deformation amount of the support member close to the edge of the display panel is smaller than that of the support member at the rest part of the display panel. Thereby resulting in a less uniform distance between the first substrate and the second substrate near the edges of the display panel than the remainder of the display panel. At the edge of the display panel, when light is irradiated from the second substrate to the first substrate, in the microcavity structure formed between the first substrate and the second substrate, reflected lights generated by the two inner surfaces of the first substrate and the second substrate interfere with each other, so that a newton ring phenomenon easily occurs in the edge region of the display panel, and the display effect of the display panel and the display device is affected.
Based on at least one of the above technical problems, embodiments of the present application provide a display panel and a display device, in which a support member, a first substrate and a second substrate are disposed and fastened to each other, the support member is located between the first substrate and the second substrate, the first substrate and the second substrate are respectively connected to two opposite ends of the support member, and the support member can support the first substrate and the second substrate. The length of the display panel along the first direction is larger than the length of the display panel along the second direction, so that the deformation amount of the display panel along the first direction is larger than the deformation amount of the display panel along the second direction. Wherein the first direction and the second direction intersect. The length of the extending direction of the supporting part is larger than the length of the supporting part along the direction vertical to the extending direction, so that the supporting effect of the extending direction of the supporting part is stronger than the supporting effect of the supporting part vertical to the extending direction. The included angle between the extending direction of the supporting piece and the first direction is smaller than 20 degrees, so that the supporting piece can well support the first direction of the display panel, the deformation of the display panel along the first direction is reduced, the distance uniformity between the first substrate and the second substrate is improved, the Newton ring phenomenon of the edge area of the display panel is weakened, and the display effect of the display panel and the display device is ensured.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The display device provided in the embodiment of the present application will be described below with reference to fig. 1 to 6.
The embodiment of the present application provides a display device, which includes a display panel 100. The display device may be a mobile or fixed terminal having the display panel 100, such as electronic paper, a mobile phone, a tablet computer, a television, a monitor, a notebook computer, a digital photo frame, a super personal computer, and a navigator.
The Display panel 100 may be an Organic Light-Emitting Diode (OLED) Display panel, a Micro Light-Emitting Diode (Micro LED or μ LED) Display panel, or a Liquid Crystal Display (LCD) Display panel.
The display panel 100 provided in the embodiment of the present application will be described below.
The present embodiment provides a display panel 100, and the display panel 100 can be applied to the display device.
As shown in fig. 1 and 2, the display panel 100 includes a first substrate 110, the first substrate 110 may include a substrate 111, and the substrate 111 may provide support for the rest of the structural layers that are subsequently disposed.
Illustratively, the substrate 111 may be a rigid substrate, for example, the material of the substrate 111 may be glass. In addition, the substrate 111 may be a flexible substrate, and a material of the substrate 111 may include at least one of Polyimide (PI), polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polyarylate, and polyethersulfone.
In this embodiment, a driving array layer 112 is disposed on a substrate 111, and a plurality of driving units are disposed in the driving array layer 112. The plurality of driving units may be arranged in an array, and the driving units are configured to drive the display panel 100 to emit light. The driving unit may include a Thin Film Transistor (TFT) and a capacitor structure, and the Thin Film Transistor may include at least one of a Low Temperature Polysilicon (LTPS) Thin Film Transistor and a metal oxide Thin Film Transistor.
In this embodiment, a light emitting layer (not shown) is disposed on a side of the driving array layer 112 facing away from the substrate 111, that is, the driving array layer 112 is located between the substrate 111 and the light emitting layer. The light emitting layer may comprise an anode layer and a cathode layer, the anode layer being located at a side of the cathode layer facing the substrate 111. The light emitting layer further includes a pixel layer and a pixel defining layer, the pixel layer being positioned between the anode layer and the cathode layer.
The pixel layer may generally include a plurality of pixels, and the pixels are light emitting units of the display panel 100. The plurality of pixels may be arranged in an array, and the plurality of pixels may include, but is not limited to, a red pixel, a green pixel, and a blue pixel, and the plurality of pixels may further include a white pixel. Wherein, the pixel limiting layer is located between two adjacent pixels, and the pixel limiting layer can be arranged around the periphery of the pixel.
The driving unit is electrically connected with the light-emitting layer and provides driving current for the pixels in the light-emitting layer so as to drive the pixels to emit light.
In this embodiment, as shown in fig. 1, the display panel 100 may include a second substrate 120, the second substrate 120 is located on a side of the light emitting layer away from the substrate 111, and the first substrate 110 and the second substrate 120 are relatively buckled. The second substrate 120 may include a cover plate, which protects the display panel 100 and prevents the display panel 100 from being scratched during use.
In this embodiment, as shown in fig. 1, the display panel 100 may include a sealing member 140, the sealing member 140 is disposed around the edges of the first substrate 110 and the second substrate 120, and the sealing member 140 is located between the first substrate 110 and the second substrate 120. One end of the sealing member 140 is connected to the first substrate 110, the other end of the sealing member 140 is connected to the second substrate 120, and the sealing member 140 is used to seal the first substrate 110 and the second substrate 120, so as to prevent water, oxygen, and the like from entering between the first substrate 110 and the second substrate 120, which may damage the display panel 100 and affect the service life of the display panel. In addition, the sealing member 140 can also form a support for the first substrate 110 and the second substrate 120.
The Y direction in fig. 3 may be a first direction, which is a longitudinal direction of the display panel 100; the X direction in fig. 3 may be a second direction, i.e., a width direction of the display panel 100; the Z direction in fig. 3 may be a third direction, which is a thickness direction of the display panel 100.
Of course, the first direction, the second direction and the third direction may be other directions, wherein the first direction, the second direction and the third direction intersect with each other two by two.
The embodiment of the present application takes the example that the length of the display panel 100 along the first direction is greater than the length of the display panel 100 along the second direction.
In this embodiment, as shown in fig. 1, the display panel 100 may include a support 130, and the support 130 is located between the first substrate 110 and the second substrate 120. One end of the support 130 is connected to the first substrate 110, for example, the support 130 may be located on a side of the pixel defining layer facing the second substrate 120 and connected to the pixel defining layer, so that the support 130 may be prevented from being pressed to affect the pixel layer. The other end of the support 130 is connected to the second base plate 120, for example, the other end of the support 130 may be connected to a cover plate. The support 130 may support the second substrate 120 to prevent the second substrate 120 from pressing the pixels under the action of gravity and atmospheric pressure, and thus damage to the pixels is prevented.
For example, the number of the supporting members 130 may be multiple, and the multiple supporting members 130 are distributed on the display panel 100 at intervals.
For example, the shape of the cross section of the support 130 along a direction parallel to the first and second directions may be a quadrilateral (rectangular, parallelogram, trapezoid, etc.), a pentagon, a hexagon, other multi-deformation, a circle, an ellipse, or other irregular shape.
The embodiment of the present application is described by taking the cross-sectional shape of the supporting member 130 as a rectangle.
Specifically, as shown in fig. 4 and 5, the cross-section of the support member 130 is rectangular. The extending direction of the supporting member 130 is the length direction of the supporting member 130, and the perpendicular direction is the width direction of the supporting member 130. The length of the supporting member 130 is L (fig. 5), and the width of the supporting member 130 is W (fig. 5). Thus, the supporting effect of the length direction of the support 130 on the display panel 100 is stronger than the supporting effect of the width direction of the support 130.
In addition, the length of the display panel 100 in the first direction is greater than the length of the display panel 100 in the second direction. Thus, the deformation amount of the display panel 100 in the first direction is larger than the deformation amount of the display panel 100 in the second direction due to the gravity and the atmospheric pressure.
As shown in fig. 5, the display panel 100 includes a first support 131 and a second support 132, a length direction of the first support 131 is parallel to a first direction, and a length direction of the second support 132 is perpendicular to the first direction. The first support 131 and the second support 132 have a length L and a width W. Taking the display panel 100 in the region C (fig. 5) as an example, the width a of the region C, the contact area between the first support 131 and the display panel 100 in the region C is L a, and the contact area between the second support 132 and the display panel 100 in the region C is W a, where L > W, and the contact area between the first support 131 and the display panel 100 in the region C is greater than the contact area between the second support 132 and the display panel 100 in the region C. The effect of the first supporting member 131 on the supporting member 130 of the display panel 100 in the C region is stronger than the effect of the second supporting member 132 on the display panel 100 in the C region.
Similarly, if the included angle between the length direction (i.e. the extending direction) of the supporting member 130 and the first direction is smaller than 90 °, the supporting effect of the supporting member 130 is stronger than the supporting effect of the second supporting member 132 on the display panel 100 in the region C. Therefore, an angle between the length direction of the supporting member 130 and the first direction may be set to be less than 90 ° to enhance the supporting effect of the supporting member 130 on the display panel 100.
Exemplarily, an included angle between the length direction of the supporting member 130 and the first direction is less than or equal to 20 °, so that the supporting member 130 forms a better support for the first direction of the display panel 100, so as to reduce a deformation amount of the display panel 100 along the first direction, improve uniformity of a distance D (fig. 1) between the first substrate 110 and the second substrate 120, thereby reducing a newton ring phenomenon in an edge region of the display panel 100, and ensuring a display effect of the display panel 100 and the display device.
The extending direction of the supporting member 130 may include an angle ranging from 5 ° to 20 ° (greater than or equal to 5 ° and less than or equal to 20 °) with respect to the first direction. For example, the angle between the extending direction of the support member 130 and the first direction may be any value between 0 °, 5 °, 10, ° 15 °, 20 °, or 0 ° -20 °. Therefore, an included angle between the extending direction of the supporting member 130 and the first direction can be avoided from being too large, so that the supporting effect of the supporting member 130 on the first direction of the display panel 100 is better.
When the included angle between the extending direction of the supporting member 130 and the first direction is 0 °, the extending direction of the supporting member 130 is parallel to the first direction, and the supporting member 130 is relatively simple to set.
The supporting member 130 provided in the embodiment of the present application was tested, the extending direction of the supporting member 130 in the test example was 0 ° to 20 ° to the first direction, the extending direction of the supporting member 130 in the comparative example was 90 ° to the first direction, and the deformation amount of the supporting member 130 in the test example and the comparative example was measured. The results are shown in table 1:
TABLE 1
As can be seen from table 1 and fig. 6, all the test examples produced smaller amounts of deformation than the comparative examples. When the included angle between the extending direction of the supporting member 130 and the first direction is 5 °, the deformation of the supporting member 130 is the smallest. An angle between the extending direction of at least one of the supporting members 130 and the first direction may be set to 5 ° to reduce the deformation of the display panel 100, so as to ensure the display effect of the display panel 100.
In some embodiments, the supporting member 130 has a first length (i.e., length L in fig. 5) along the extending direction, the supporting member 130 has a second length (i.e., width W in fig. 5) perpendicular to the extending direction, and a ratio of the first length to the second length may range from greater than 1 to less than or equal to 2. The ratio of the first length to the second length may range from 1.2 to 1.8. For example, the ratio of the first length to the second length may be 1.1, 1.3, 1.5, 1.7, 2, or any value between 1-2. Thereby preventing the second length from being too small, and the supporting member 130 has a better supporting effect on the second direction of the display panel 100.
Note that, in which the first length and the second length both lie in an XY plane, the plane of the display panel 100 may be referred to as an XY plane (fig. 4).
As shown in fig. 1, since the sealing member 140 is disposed at the edges of the first substrate 110 and the second substrate 120 (i.e., the edges of the display panel 100), the sealing member 140 forms a support for the second substrate 120. Therefore, the edge of the display panel 100 is supported more than the center of the display panel 100. Wherein, the edge of the display panel 100 is arranged around the periphery of the center of the display panel 100. The deformation amount of the edge of the display panel 100 is smaller than that of the center of the display panel 100. If the center of the display panel 100 is better supported, the deformation of the edge of the display panel 100 and the center of the display panel 100 can be closer, so that the distance between the first substrate 110 and the second substrate 120 is more uniform, and the display effect of the display panel 100 is improved.
The following describes a specific implementation of the supporting member 130 between the edge of the display panel 100 and the center of the display panel 100.
In a first implementation, the ratio of the first length (length L in fig. 5) to the second length (width W in fig. 5) of the support member 130 in at least some different regions of the display panel 100 is not equal. In the region of the display panel 100 where the deformation is greater, the ratio of the first length to the second length of the supporting member 130 is greater, so that the first direction of the display panel 100 in the region is better supported to reduce the deformation of the display panel 100 in the region; in the region where the deformation amount of the display panel 100 is small, the ratio of the first length to the second length of the supporting member 130 is small, so that the deformation amounts of the positions of the display panel 100 are consistent, thereby ensuring the display effect of the display panel 100.
Illustratively, the ratio of the first length to the second length at the edge of the display panel 100 is smaller than the ratio of the first length to the second length at the center of the display panel 100. That is, the support member 130 located at the center of the display panel 100 has a larger L/W (fig. 5), so as to provide better support for the first direction of the center of the display panel 100; the L/W (fig. 5) of the supporting member at the edge of the display panel 100 is smaller, so that the deformation amount of the edge of the display panel 100 and the center of the display panel 100 is closer to each other, thereby improving the display effect of the display panel 100.
Illustratively, the ratio L/W (fig. 5) of the first length to the second length may gradually decrease along a direction from the center of the display panel 100 to the edge of the display panel 100. The sudden change of the ratio of the first length to the second length of the supporting members 130 can be avoided, and the supporting force of the supporting members 130 on the display panel 100 does not form a sudden change, so that the supporting effect of each supporting member 130 on the display panel 100 is better.
In a second implementation, the initial thickness of the support members 130 in at least partially different regions of the display panel 100 is not equal. In the region of the display panel 100 where the deformation amount is large, the initial thickness of the supporting member 130 is large, and the thickness of the supporting member 130 after being pressed and deformed is large; in the region where the deformation amount of the display panel 100 is small, the initial thickness of the supporting member 130 is small, so that the thicknesses of the supporting members 130 in the respective regions after being extruded and deformed are consistent, thereby ensuring the display effect of the display panel 100.
The "initial thickness" refers to a thickness of the support member 130 along the third direction Z when the support member 130 is not deformed by the first substrate 110, the second substrate 120, and the atmospheric pressure.
Illustratively, the initial thickness of the support 130 at the edge of the display panel 100 is smaller than the initial thickness of the support 130 at the center of the display panel 100. Thus, the initial thickness of the support 130 at the center of the display panel 100 is larger, the thickness of the support 130 at the center of the display panel 100 after deformation is larger, and the deformation amount at the center of the display panel 100 is smaller; the initial thickness of the supporting member 130 at the edge of the display panel 100 is smaller, so that the deformation amount of the center of the display panel 100 is more consistent with the deformation amount of the edge of the display panel 100, thereby improving the display effect of the display panel 100.
Illustratively, the initial thickness of the support member 130 is gradually reduced in a direction from the center of the display panel 100 to the edge of the display panel 100. Therefore, the sudden change of the initial thickness of the supporting member 130 can be avoided, and the supporting force of the supporting member 130 on the display panel 100 does not form a sudden change, so that the supporting effect of the supporting member 130 on the display panel 100 is better.
In a third implementation manner, the extending direction of the supporting members 130 in at least some different regions of the display panel 100 is not equal to the included angle of the first direction. In the region of the display panel 100 where the deformation is large, the included angle between the extending direction of the supporting member 130 and the first direction may be set to be small, so that the supporting effect of the supporting member 130 on the display panel 100 is good, so as to reduce the deformation of the display panel 100 along the region; in the area of the display panel 100 where the deformation is small, the included angle between the extending direction of the supporting member 130 and the first direction may be set to be large, so that the deformation of the display panel 100 in each area is consistent, and the display effect of the display panel 100 is ensured.
Illustratively, the extending direction of the supporting member 130 forms an angle with the first direction in a range of 5 ° to 20 °, and the extending direction of the supporting member 130 at the edge of the display panel 100 forms an angle with the first direction, which is greater than the extending direction of the supporting member 130 at the center of the display panel 100. As shown in table 1 and fig. 6, when the included angle between the extending direction of the supporting member 130 and the first direction is within the range, the smaller the included angle is, the smaller the deformation amount of the supporting member 130 is, and the better the supporting effect on the display panel 100 is. So set up, can form better support to display panel 100 center to can make the deflection of display panel 100 edge and display panel 100 center comparatively close, with the display effect who promotes display panel 100.
Illustratively, the extending direction of the supporting member 130 gradually increases an angle with the first direction along a direction from the center of the display panel 100 to the edge of the display panel 100. Therefore, the sudden change of the included angle between the extending direction of the supporting member 130 and the first direction can be avoided, and the supporting acting force of the supporting member 130 on the display panel 100 cannot be suddenly changed, so that the supporting effect of the supporting member 130 on the display panel 100 is better.
In a fourth implementation, the distribution density of the supporting members 130 in at least some different regions of the display panel 100 is different. In the region with larger deformation in the display panel 100, more supporting members 130 can be arranged in a unit area, so that the display panel 100 in the region can be better supported, and the deformation of the display panel 100 in the region can be reduced; in the region where the deformation amount of the display panel 100 is small, a small number of the supporting members 130 may be disposed in a unit area, so that the deformation amounts of the regions of the display panel 100 are consistent, thereby ensuring the display effect of the display panel 100.
Here, the "distribution density" refers to the number of the supporting members 130 included in the display panel 100 per unit area.
Illustratively, the distribution density of the supporting members 130 at the edge of the display panel 100 is less than the distribution density of the supporting members 130 at the center of the display panel 100. Therefore, the number of the supporting members 130 distributed at the center of the display panel 100 is large, the center of the display panel 100 is supported well, and the deformation of the center of the display panel 100 is reduced; the number of the supporting members 130 distributed at the edge of the display panel 100 is smaller, so that the deformation amount of the edge of the display panel 100 and the deformation amount of the center of the display panel 100 are closer to each other, thereby improving the display effect of the display panel 100.
Illustratively, the distribution density of the supporting members 130 is gradually decreased along a direction from the center of the display panel 100 to the edge of the display panel 100. Thus, the distribution density of the supporting members 130 does not change abruptly, so that the supporting effect of the supporting members 130 on the display panel 100 is better.
