Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Fig. 1 is a schematic structural diagram of a transparent display device. As shown in fig. 1, the transparent display device includes a display panel and a light source 40 disposed at a side of the display panel. The display panel comprises a first substrate 10 and a second substrate 20 which are oppositely arranged, and further comprises a liquid crystal 30 arranged between the first substrate 10 and the second substrate 20, wherein the liquid crystal 30 comprises PNLC, and the liquid crystal 30 is packaged between the first substrate 10 and the second substrate 20 through frame sealing glue 31. The light source 40 is typically a Mini LED (Mini-LED) disposed at a side of the display panel.
As shown in fig. 1, the light emitted from the light source 40 mainly has three transmission paths, i.e., a first path 41, a second path 42, and a third path 43, when being transmitted inside the display panel. The light on the first path 41 does not satisfy the total reflection condition in the display panel, therefore, the light on the first path 41 directly exits from the panel and becomes useless light, and the contrast of the panel is reduced after the light on the first path 41 enters human eyes, which affects the display effect. The light on the second path 42 is directed in a direction parallel to the panel to exit the other side of the panel as waste light. The light on the third path 43 satisfies the total reflection condition in the display panel, so that the light on the third path 43 is totally reflected when it irradiates the critical surface between the first substrate 10 and the air, and the totally reflected light is scattered when it passes through the liquid crystal scattering state. The light on the third path 43 is also totally reflected when it irradiates the critical surface between the second substrate 20 and the air, so that the light on the third path 43 is transmitted in the horizontal direction and totally reflected multiple times inside the display panel, and the totally reflected light is partially scattered when passing through the scattering state of the liquid crystal, and the scattered light enters human eyes to realize bright state display. Therefore, in the display panel shown in fig. 1, only the light on the third path 43 is useful light, and the light on the first path 41 and the second path 42 is useless light, so that the PNLC transparent display device has more light loss, and the brightness and the contrast of the display product are reduced.
In order to solve the above technical problem, an embodiment of the present invention provides a display device. The display device comprises a display panel and a light source, wherein the side part of the display panel is provided with a light incident surface which is inclined relative to the plane of the display panel, and light rays emitted by the light source are incident into the display panel from the light incident surface.
Compared with the display device shown in fig. 1, the display device of the embodiment of the invention has the advantages that the light emitted by the light source is emitted into the display panel from the light incident surface inclined relative to the plane where the display panel is located, the light transmitted along the first path and the second path in fig. 1 can be reduced, the light passing through the liquid crystal scattering state in the display panel is increased, and the light passes through the liquid crystal scattering state to generate scattering light, so that the light loss is reduced, the useful light is increased, the useless light is reduced, the utilization rate of the light source is increased, and the brightness and the contrast of the display device are improved.
The technical contents of the present invention will be described in detail by specific embodiments.
The first embodiment:
fig. 2 is a schematic structural diagram of a display device according to a first embodiment of the invention. As shown in fig. 2, the display device includes a display panel 100 and a light source 40. The display panel 100 has a light incident surface 50 on a side portion thereof, and the light incident surface 50 is inclined with respect to a plane in which the display panel 100 is located. The light source 40 is disposed at the light incident surface 50, and the light emitted from the light source 40 is incident into the display panel 100 through the light incident surface 50.
As can be seen from the analysis of the structure of the display device shown in fig. 1, the light source 40 is disposed at the side of the display panel, so that most of the light emitted from the light source 40 is transmitted along the first path 41 and the second path 42 in the display panel without passing through the liquid crystal layer, resulting in a large loss of light, and thus the brightness and contrast of the display device are reduced.
Compared with the display device shown in fig. 1, the light incident surface 50 is inclined relative to the plane of the display panel 100, and the light emitted by the light source 40 is incident into the display panel 100 from the light incident surface 50, so that the light transmitted along the first path and the second path in fig. 1 can be reduced, the light passing through the liquid crystal scattering state in the display panel 100 is increased, and the light passing through the liquid crystal scattering state generates scattering light, thereby reducing light loss, increasing useful light, reducing useless light, increasing the utilization rate of the light source, and improving the brightness and contrast of the display device.
In one embodiment, the display panel 100 includes a first substrate 10 and a second substrate 20 disposed opposite to each other, and further includes a liquid crystal 30 disposed between the first substrate 10 and the second substrate 20. The liquid crystal 30 comprises a polymer network liquid crystal. The liquid crystal 30 is encapsulated between the first substrate 10 and the second substrate 20 by the sealant 31. The light incident surface 50 is disposed at a side portion of the first substrate 10 or the second substrate 20, and the light emitted from the light source 40 enters the display panel 100 through the light incident surface 50.
In the present embodiment, the first substrate 10 and the second substrate 20 are both glass substrates. The light incident surface 50 may be formed at a side portion of the first substrate 10 or the second substrate 20 by a polishing method.
In one embodiment, the included angle θ between the light incident surface 50 and the plane of the first substrate or the second substrate, i.e. the horizontal direction, is greater than or equal to 41 °. As shown in fig. 1, most of the light emitted from the light source 40 enters the display panel in a direction perpendicular to the light incident surface 50, for example, the light 61 enters the display panel perpendicularly from the light incident surface 50, and since θ is greater than or equal to 41 °, the incident angle α of the light 61 on the critical plane between the second substrate 20 and the air is also greater than or equal to 41 °, that is, the incident angle α of the light 61 on the critical plane between the second substrate 20 and the air is greater than the total reflection critical angle, so that the light 61 is totally reflected in the display panel and is transmitted in the horizontal direction in the display panel. In the process of transferring along the horizontal direction, the light totally reflected by the light ray 61 at each time is partially scattered when passing through a liquid crystal scattering state, the times of the light ray 61 passing through the liquid crystal are increased, the utilization rate of a light source is increased, and the brightness and the contrast of the display device are improved. Therefore, when θ is set to be greater than or equal to 41 °, most of the light emitted from the light source 40 is totally reflected in the display panel 100 after entering the display panel 100, so that the utilization rate of the light source is greatly improved, and the brightness and the contrast of the display device are improved.
In order to make the light emitted from the light source 40 enter the display panel perpendicular to the light incident surface as much as possible, in one embodiment, the light source 40 includes a plurality of Mini-LEDs (Mini-LEDs), and the Mini-LEDs are uniformly arranged on the light incident surface. Therefore, most of the light emitted by the Mini-LED enters the display panel perpendicular to the light incident surface 50, so that most of the light in the display panel is totally reflected on the critical surface between the substrate and the air, the utilization rate of the light source is improved, and the brightness and the contrast of the display device are improved.
In one embodiment, as shown in FIG. 1, the light incident surface 50 is disposed at the edge of the side of the first substrate 10 facing away from the liquid crystal 30, and the light source 40 is disposed parallel to the light incident surface 50. With the structure, light emitted from the light source 40 can directly pass through the liquid crystal after entering the display panel from the light incident surface 50, so that the utilization rate of the light source is further improved, and the brightness and the contrast of the display device are improved. In one embodiment, the light incident surface may be further disposed at an edge of a side portion of the first substrate 10 near the liquid crystal side.
It is understood that, in another embodiment, the light incident surface 50 may be disposed at an edge of a side of the second substrate 20 facing away from the liquid crystal 30, as shown in fig. 3, and fig. 3 is a schematic structural diagram of a display device in another embodiment. In one embodiment, the light incident surface may be further disposed at an edge of a side of the second substrate 20 near the liquid crystal side.

Unlike the first embodiment, in the second embodiment of the present invention, as shown in fig. 4, the light incident surface 50 includes a first light incident surface 51 disposed at a side of the first substrate 10 and a second light incident surface 52 disposed at a side of the second substrate 20. The light rays emitted from the light source 40 enter the display panel 100 through the first light incident surface 51 and the second light incident surface 52.
An included angle theta 1 between the first light incident surface 51 and the plane where the first substrate 10 is located is greater than or equal to 41 degrees, and an included angle theta 2 between the second light incident surface 52 and the plane where the second substrate 20 is located is greater than or equal to 41 degrees.
In one embodiment, the first light incident surface 51 is disposed at an edge of a side portion of the first substrate 10 near the liquid crystal 30, the second light incident surface 52 is disposed at an edge of a side portion of the second substrate 20 near the liquid crystal 30, and the light source 40 is disposed between the first light incident surface 51 and the second light incident surface 52, as shown in fig. 4. In the display device, the light emitted from the light source 40 can enter the display panel through the first light incident surface 51 and the second light incident surface 52, so that the utilization rate of the light source 40 is further improved, and the brightness and the contrast of the display device are improved.
Fig. 5 is a schematic structural diagram of a display device in another embodiment. As shown in fig. 5, the first light incident surface 51 is disposed at an edge of the side portion of the first substrate 10 facing away from the liquid crystal 30, and the second light incident surface 52 is disposed at an edge of the side portion of the second substrate 20 facing away from the liquid crystal 30. The light source 40 is in a C-shaped structure, the light source 40 is arranged along the first light incident surface and the second light incident surface, and the shape of the light source 40 is matched with the side structure of the display panel. The assembly of the light source and the display panel is facilitated.
