Hereinafter, a display panel and a display device provided in an embodiment of the present disclosure will be described in detail with reference to the drawings.

An embodiment of the present disclosure provides a display panel. Fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present disclosure. As shown in fig. 1, the display panel 100 includes a micro led backlight module 110, a parallax barrier 120, and a liquid crystal display panel 130; the micro light emitting diode backlight module 110 includes a substrate 112 and a plurality of micro light emitting diodes 114 on the substrate 112; the parallax baffle 120 is located at the light emitting side of the micro light emitting diode backlight module 110; the parallax barrier 120 includes a plurality of light-transmitting portions 124 and a plurality of light-shielding portions 122, and the plurality of micro light-emitting diodes 114 are provided in one-to-one correspondence with the plurality of light-transmitting portions 124. The light-transmitting portion is a portion through which light can pass, and the light-shielding portion is a portion through which light cannot pass.

In the display panel provided by the embodiment of the present disclosure, the plurality of micro light emitting diodes are disposed in one-to-one correspondence with the plurality of light transmitting portions, so that light beams in a specific direction can be provided, and thus, a 3D image can be displayed; and the display panel can also realize the display of 2D images and the fusion display of the 2D images and the 3D images. In addition, because the brightness of each micro light-emitting diode can be controlled independently, and the micro light-emitting diodes are arranged in one-to-one correspondence with the light-transmitting parts, the display panel can finely adjust the backlight brightness required by different sub-display areas on the liquid crystal display panel, thereby realizing higher area dimming and improving the brightness and the contrast of a display picture. On the other hand, when the display panel displays a 3D image, the display panel can improve the resolution of 3D display because each micro light emitting diode can be used as a separate light source.

In some examples, an orthographic projection of each micro light emitting diode 114 on the substrate 112 overlaps with an orthographic projection of a corresponding light-transmissive portion 124 on the substrate 112. Thus, the light emitted from each micro light emitting diode can be emitted from the corresponding light transmission portion.

In some examples, each micro-led 114 has a largest dimension in a direction parallel to the substrate base 112 that is less than 50 microns. Therefore, the micro light-emitting diode can provide higher regional dimming performance.

For example, each of the micro light emitting diodes 114 has a dimension of less than 50 μm in the arrangement direction of the plurality of light-transmitting portions 124 and the plurality of light-shielding portions 122 included in the parallax barrier 120.

In some examples, as shown in fig. 1, the liquid crystal display panel 130 includes a plurality of sub-display regions 132, the plurality of micro light emitting diodes 114 are disposed in one-to-one correspondence with the plurality of sub-display regions 132, and an orthogonal projection of each micro light emitting diode 114 on the substrate 112 overlaps an orthogonal projection of the corresponding sub-display region 132 on the substrate 112. Therefore, the light emitted by each micro light-emitting diode can provide backlight for the corresponding sub-display area.

In some examples, as shown in fig. 1, each sub-display region 132 includes a plurality of pixel cells 1320; for example, each sub-display region may include 16 pixel cells forming a 4 × 4 matrix, 8 pixel cells forming an 8 × 1 matrix, or 9 pixel cells forming a 9 × 1 matrix. Of course, embodiments of the present disclosure include, but are not limited to, this.

Therefore, the display panel can better attach the miniature light-emitting diode backlight module to the parallax baffle through the first optical adhesive layer, improve the alignment precision between the miniature light-emitting diode backlight module and the parallax baffle, and also can better attach the parallax baffle to the liquid crystal display panel through the second optical adhesive layer, and improve the alignment precision between the parallax baffle and the liquid crystal display panel.

For example, the material of the first Optical Adhesive layer 141 and the second Optical Adhesive layer 142 may be transparent Optical Adhesive (OCA). Of course, embodiments of the present disclosure include, but are not limited to, such.

In some examples, as shown in fig. 1, the micro led backlight module 110 further includes an optical adhesive 116, and the optical adhesive 116 is located between the micro leds 114 and the first optical adhesive layer 141, so that the micro led backlight module can be attached to the parallax barrier more tightly, thereby avoiding defects such as bubbles.

For example, the material of the Optical glue 116 may be transparent Optical Resin (OCR). Of course, embodiments of the present disclosure include, but are not limited to, this.

In some examples, the substrate 112 may be a rigid substrate or a flexible substrate; when the substrate base plate is a rigid substrate base plate, the substrate base plate can be made of glass, quartz, plastic and other materials; when the substrate is a flexible substrate, the material of the substrate may be polyimide or the like.

In some examples, the micro light emitting diode may be a gallium nitride (GaN) light emitting diode. Of course, the embodiments of the present disclosure include, but are not limited to, the micro light emitting diode may also be a quantum dot light emitting diode (QLED).

Fig. 2 is a schematic plan view of a parallax barrier in a display panel according to an embodiment of the present disclosure. As shown in fig. 2, the plurality of light-transmitting portions 124 and the plurality of light-shielding portions 122 are alternately arranged in both the first direction and the second direction, and the first direction intersects with the second direction.

For example, as shown in fig. 2, the first direction and the second direction are perpendicular to each other.

For example, as shown in fig. 2, each light transmitting portion 124 has a rectangular planar shape, and each light shielding portion 122 has a rectangular planar shape. However, embodiments of the present disclosure include, but are not limited to, the planar shape of each light-transmitting portion and the planar shape of each light-shielding portion may also take other shapes such as a parallelogram according to a specific 3D optical design.

In addition, because the brightness of each micro light-emitting diode can be controlled independently, and the micro light-emitting diodes are arranged in one-to-one correspondence with the light-transmitting parts, the display panel can finely adjust the backlight brightness required by different sub-display areas on the liquid crystal display panel, thereby realizing higher area dimming and improving the brightness and the contrast of a display picture. On the other hand, when the display panel displays a 3D image, the display panel can improve the resolution of 3D display because each micro light emitting diode can be used as a separate light source.

In some examples, as shown in fig. 3, the micro light emitting diode backlight module 110 further includes a color conversion layer 118, where the color conversion layer 118 is located on a side of the plurality of micro light emitting diodes 114 away from the substrate 112; the micro light emitting diodes 114 are configured to emit blue light, and the color conversion layer 118 is configured to convert the blue light emitted by the micro light emitting diodes 114 into red light and green light. Therefore, the miniature light-emitting diode backlight module can provide white backlight.

In some examples, as shown in fig. 3, the color conversion layer 118 includes at least one of a quantum dot thin film and a phosphor film having the same effect. It should be noted that the quantum dot thin film may include quantum dots, and the quantum dots may convert blue light with higher energy into red light or green light; in addition, the color conversion layer includes, but is not limited to, a quantum dot film and a fluorescent film, and other suitable materials may also be used.

In some examples, as shown in fig. 3, the display panel 100 further includes a first optical glue layer 141 and a second optical glue layer 142; the first optical adhesive layer 141 is located between the micro led backlight module 110 and the parallax barrier 120; the second optical adhesive layer 142 is located between the parallax barrier and the liquid crystal display panel. Therefore, the display panel can better attach the miniature light-emitting diode backlight module to the parallax baffle through the first optical adhesive layer, improve the alignment precision between the miniature light-emitting diode backlight module and the parallax baffle, and also can better attach the parallax baffle to the liquid crystal display panel through the second optical adhesive layer, and improve the alignment precision between the parallax baffle and the liquid crystal display panel.
