However, in some application scenarios, such as outdoor direct-view LED advertising display screens, the viewer angle is generally a downward viewing angle, while for direct-view LED center control screens in a car, the viewer angle is generally a downward viewing angle. When the viewing angle direction of watching is not perpendicular with the display screen, when the deviation angle is great, the image brightness may be reduced, the display effect is not good, and meanwhile, due to the reflection of the viewing angle ambient light, the problem of the poor viewing effect may also be caused.

Therefore, how to make the LED display still have a better viewing effect in different application scenarios is an urgent problem to be solved.

A schematic illustration of a preferred embodiment of the present application is given in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. In order to express the technical solutions of the present application more clearly, the solutions shown in the drawings may be simplified or enlarged to illustrate the technical features, and are not used to limit the embodiments of the present application.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

For convenience of understanding, the direct display type display panel provided in the present embodiment is described below by way of example with reference to the accompanying drawings.

The first embodiment is as follows:

an exemplary direct display panel 100, as shown in fig. 1a, 1b, 1c, 6, and 11, includes a substrate 10, a plurality of pixel units 11 disposed on a front surface of the substrate 10, and a light-transmissive encapsulation layer 12 disposed on the front surface of the substrate 10 and hermetically covering each pixel unit 11, a light deflection layer 13 disposed on a region of the light-transmissive encapsulation layer 12 away from the front surface of the substrate 10, a light-emitting surface of the light deflection layer 13 includes a plurality of parallel strip-shaped protruding ribs, each of which is formed by a deflection surface 131 and a connection surface 132, the connection surface is connected between adjacent deflection surfaces, the deflection surface 131 is disposed at an acute angle with respect to the front surface of the substrate 10, the connection surface 132 is disposed at an included angle of less than or equal to 90 degrees with respect to the front surface of the substrate 10, projections of the deflection surfaces on the front surface of the substrate are continuously spaced, and each deflection surface is configured to deflect at least a portion of light incident on the deflection surface from a pixel unit toward a predetermined viewing region, and to reverse the reflected path of at least a portion of the ambient light incident from the exterior toward the intended viewing area. The deflection surface 131 and the connection surface 132 form a micro-protrusion structure in the form of a triangular prism, i.e. the cross section of the strip-shaped prism in this application is triangular. In this example, the deflection surfaces 131 are rectilinear planes, the connection surfaces 132 are also rectilinear planes, and the deflection surfaces 131 are parallel to each other and the connection surfaces are also parallel to each other. In this embodiment, the included angle between the deflecting surface 131 and the front surface of the substrate 10 is 25 °, and in other embodiments, the included angle between the deflecting surface 131 and the front surface of the substrate 10 (i.e., the included angle between the side of the deflecting surface 131 facing the front surface of the substrate 10 and the front surface of the substrate 10) may be other angles, for example, 30 ° or 45 ° may be set according to the requirement of the actual application on the deflecting angle of the light.

The pixel unit 11 in this embodiment includes a red LED light emitting chip, a blue LED light emitting chip, and a green LED light emitting chip. It should be understood that the light emitting chip in the present embodiment may be a Micro light emitting chip, for example, but not limited to, at least one of a Mini LED chip and a Micro LED chip, and may also be a common light emitting chip with a size of 200 micrometers or more. In other embodiments, in the non-direct display type display panel, the light emitting chip may also be a normal light emitting chip or a vertical light emitting chip, or a mixture of the above different types of chips, and may be flexibly set according to actual application requirements.

In this embodiment, the connection surface 132 is perpendicular to the front surface of the substrate 10, so that the connection surface 132 forms a right triangle shape with the deflection surface 131 and the bottom of the light deflection layer 13 when viewed from the side. The deflecting surface 131 and the connecting surface 132 are in the form of a slightly protruding structure of a triangular prism bar on the light-transmitting encapsulation layer 12. Since the connecting surface 132 mainly serves to connect the adjacent deflecting surfaces 131, disposing the connecting surface 132 perpendicular to the substrate 10 can reduce the incidence of light rays perpendicular to the substrate 10 into the connecting surface, so that most of the light rays perpendicular to the substrate 10 are deflected by the deflecting surfaces 131.

In the present application, in order to make all the light emitted from the pixel unit 11 perpendicular to the substrate 10 refracted through the deflection surfaces 131, it is preferable to arrange each of the deflection surfaces 131 without a gap between the projections on the substrate 10 so that each of the deflection surfaces 131 can cover the substrate 10. Or in order to make most of the light rays perpendicular to the substrate 10 refractable through the deflection surface 131, the projection of each deflection surface 131 on the substrate 10 is set to be larger than the projection area of each connection surface 132 on the substrate 10, so that most of the light rays emitted from the pixel unit 11 can be directionally deflected through the deflection surface 131.

A driving chip 101 of an LED light emitting chip is provided on the back surface of the substrate 10 to drive each pixel unit 11 to operate.

Referring to fig. 6, in the present embodiment, light emitted from the pixel unit 11 and emitted perpendicularly to the front surface of the substrate 10 (indicated by an arrow in the vertical direction in the figure) is incident on the light-transmitting encapsulation layer 12 and reaches the deflection surface 131, so that the light passes through the deflection surface 131 and enters the air to be refracted and deflected. In this embodiment, the incident angle is 25 °, the refractive index of the light-transmissive encapsulating layer 12 is 1.81, so that the emergent angle of the refracted and deflected light is 50 °, and the light is deflected to the direction of the viewer R after being emitted, that is, the light deflecting layer 13 deflects the light emitted by each pixel unit 11 toward a predetermined angle (in this embodiment, the predetermined angle is the direction of the viewer R). Thereby improving the display brightness and the display effect of the viewing angle. Fig. 6 only illustrates the case of deflecting the light emitted perpendicular to the substrate 10, please refer to fig. 11, 12, and 13, in which other light emitted from the pixel unit 11 is also deflected to the viewing angle side of the viewer R through the deflecting surface 131, so that the viewer R can obtain a better viewing angle at the position. Specifically, as shown in fig. 11, 12, and 13, arrow a indicates that a part of light (including vertical or non-vertical light) emitted from the pixel unit 11 is deflected by the deflecting surface 131 and directed to the viewer R at the viewing region, and arrow F indicates that a reflection path of ambient light directly facing the substrate 10 after being incident on the deflecting surface 131 is deflected in a reverse direction toward the viewing region, i.e., deviates from a viewing angle of the viewer R, so that a reflection path of ambient light partially externally directed to the direct display panel 100 deviates from the viewing direction, thereby reducing a light reflection effect at the viewing angle.

In this embodiment, the light transmissive encapsulation layer 12 is a light transmissive encapsulation adhesive, the light deflection layer 13 is integrally formed on the upper surface of the light transmissive encapsulation layer by a molding process, and the upper surface of the light transmissive encapsulation adhesive layer is an area away from the front surface of the substrate 10.

As shown in fig. 2, a protective film 121 may be further provided on the light-transmitting encapsulation layer 12 in order to protect the light-transmitting encapsulation layer 12.

In this embodiment, the material of the light-transmitting encapsulating adhesive layer includes, but is not limited to, any one of epoxy resin and silica gel.

In some application scenarios, a light diffusion medium may be disposed in the light-transmitting encapsulation layer 12 for scattering light emitted by the LED light emitting chip in the pixel unit 11, in this embodiment, the light diffusion medium includes, but is not limited to, light diffusion powder, and may also be other dielectric materials, and an appropriate material may be flexibly selected as needed as long as the light diffusion medium can diffuse light and improve brightness, so that light entering the light deflection layer 13 is more uniform. The light-transmitting encapsulation layer 12 may be any one of a transparent adhesive layer, a semi-transparent adhesive layer, or a black light-transmitting adhesive layer.

In other embodiments, the light-transmitting encapsulation layer 12 may also be formed by a mold, and the light deflection layer 13 is formed on the corresponding mold, and the light-transmitting encapsulation adhesive is cured and formed in the mold by heating or natural placement, and then is demolded to form the light-transmitting encapsulation layer 12 and the light deflection layer 13 integrally formed therewith.

In this example, the deflection surfaces 131 shown in fig. 1c and fig. 2 are parallel to each other to ensure that the deflection surfaces 131 deflect the light emitted by the pixel unit 11 in the same direction by a certain angle, in other embodiments, as shown in fig. 9, the deflection surfaces 131 may also be arc surfaces, and if the deflection surfaces 131 are flat surfaces, the uniformity of the deflection angles for deflecting the light is the best, but it should be understood that, in the manufacturing process, an absolute plane may not be possible, so that the deflection surfaces 131 may actually be curved surfaces with a certain radian. As shown in fig. 9, after the light rays shown by the arrows enter the deflection surface 131, the angles of deflection are different because the angles of incidence are different, but the light rays are also deflected substantially to the left side shown in fig. 9, so the deflection surface 131 is a curved surface, and the light rays entering the deflection surface 131 can be deflected substantially toward a predetermined angle, but the uniformity of the angles of deflection is not good as the uniformity of planes. In some application occasions, under the condition that the consistency of the deflection angle of the light is not good, the deflected light can be scattered in a certain range, the light intensity of the viewing angle can be weakened, the better viewing angle is correspondingly enlarged, the light and the picture seen by the viewing angle are softer, if the brightness of the light emitted by the pixel unit is too high, the deflection surface 131 has a certain radian, the light seen by the viewing angle is softer after the light is deflected, the better viewing angle is larger, and the method is more suitable for some application scenes. Preferably, the arc of the deflecting surface 131 should not exceed 45 °. Otherwise, the shape of the deflected light may be seriously deformed, which may affect the image quality.

In another embodiment, in order to facilitate manufacturing, as shown in the optical deflection layer 13 shown in fig. 7, 8, and 10, the deflection surface 131 and the connection surface 132 are transitionally connected by a curved surface, which facilitates demolding and improves yield rate when manufacturing the deflection surface 13, and the curved surface in this embodiment is a rounded curved surface.

In the present embodiment, as shown in fig. 1, the deflection surface 13 is disposed horizontally, parallel to the upper and lower sides of the direct display panel 100, and the deflection surface 131 is inclined from bottom to top, so as to deflect the light emitted from the pixel unit 11 and emitted from the vertical substrate 10 to the viewing area of the upper side, so that the viewer has a better viewing angle in the top view angle. In another embodiment, as shown in fig. 14, the deflecting surface 13 may be disposed at an inclined angle of 45 ° with respect to the upper and lower sides of the direct display panel 100, and the deflecting surface 131 is inclined from the upper right to the lower left, so as to deflect the light emitted from the pixel unit 11 and perpendicular to the substrate 10 to the viewing area at the lower left, such that the viewing angle at the upper right of the viewer at the lower left has a better viewing angle. In light of the present embodiment, those skilled in the art can also see that the deflecting surface is disposed at other angles to make the viewer obtain a better viewing picture at a specific viewing angle. This embodiment is not described herein.

The second embodiment:

as shown in fig. 3, unlike the first embodiment, in the present embodiment, the light deflecting layer 13 is specifically disposed on the optical film layer on the light transmissive encapsulating layer 12, the optical film 122 is disposed on the side of the light transmissive encapsulating layer 12 away from the front surface of the substrate 10, the light deflecting layer 13 is disposed on the upper surface of the optical film 122 (i.e., the side away from the front surface of the substrate 10), and the light transmissive encapsulating layer 12 is disposed between the substrate 10 and the optical film 122. Also belongs to an embodiment that the side of the light-transmitting encapsulation layer 12 away from the front surface of the substrate 10 is provided with a light deflection layer 13.

The advantage of this is that the optical film 122 can be produced separately, and when in use, the optical film 122 is only needed to be adhered to the light-transmitting encapsulation layer 12, so that the installation is simple, and the optical film 122 with different deflection angles can be selected or replaced according to the use requirements; referring to fig. 1c and fig. 14, the optical film 122 is attached to the light-transmitting encapsulation layer 12 in parallel or at an inclined angle of 45 °, so that a viewer can obtain a better viewing image at a specific viewing angle, and the application is more flexible and wider.

In the present embodiment, the optical film 122 includes a substrate on which the light deflecting layer 13 is molded. UV glue may be applied to the substrate, and a micro-bump structure (i.e., the structure of the light deflection layer 13) may be printed on the glue on the surface of the substrate by a plate wheel, and then the glue may be cured by UV curing to form the light deflection layer 13. The substrate of the optical film 122 may be PET, but may be other materials. In this embodiment, the optical film 122 may be any one of a transparent optical film, a semi-transparent optical film, or a black transparent optical film, and an appropriate type of optical film may be flexibly selected according to actual needs.

Example three:

in this embodiment, in addition to the embodiment shown in fig. 1c, as shown in fig. 4, a light deflecting layer (i.e., a first light deflecting layer 13a) is disposed on a side of the light-transmissive encapsulating layer 12 away from the front surface of the substrate 10, an optical film 30 is further disposed on a side of the light-transmissive encapsulating layer 12 away from the front surface of the substrate 10, a light deflecting layer (i.e., a second light deflecting layer 13b) is also disposed on a side of the optical film 30 away from the front surface of the substrate 10, the light-transmissive encapsulating layer 12 is disposed between the substrate 10 and the optical film 30, and the light deflecting layer is also an embodiment in which the light deflecting layer is disposed on a side of the light-transmissive encapsulating layer 12 away from the front surface of the substrate 10, and the light deflecting layers in this embodiment include two layers, that is the first light deflecting layer 13a and the second light deflecting layer 13 b.

This has an advantage that by providing the first light deflecting layer 13a on the light-transmitting encapsulation layer 12 and the second light deflecting layer 13b on the optical film, the first and second light deflecting layers successively deflect the light emitted from the pixel unit 11 twice, thereby obtaining a larger deflection angle. As shown in fig. 7, light rays indicated by arrows enter the first optical deflection layer 13a at an incident angle of 25 °, are deflected, enter the second optical deflection layer 13b again, are deflected again, and then exit at a deflection angle of 75 °.

In this embodiment, the deflection angle of the deflection surface 131a of the first light deflection layer 13a with respect to light is equal to the deflection angle of the deflection surface 131b of the second light deflection layer 13b with respect to light. In other embodiments, the deflection angle of the deflection surface 131a of the first light deflection layer 13a to light may not be equal to the deflection angle of the deflection surface 131b of the second light deflection layer 13b to light. The flexible setting can be performed according to the requirement of the deflection angle of the light of the pixel unit 11 in practical application.

In other embodiments, an additional optical film 30 may be added on the basis of the present embodiment to deflect the light again to obtain a larger deflection angle.

Example four:

referring to fig. 5, the direct display type display panel 100 provided in this embodiment includes a substrate 10, a plurality of pixel units 11 disposed on a front surface of the substrate 10, and a light-transmissive encapsulation layer 12 disposed on the front surface of the substrate 10 and hermetically covering each pixel unit 11. A driving chip 101 for driving the pixel unit 11 to emit light is provided on the back surface of the substrate 10. The side of the light-transmitting packaging layer 12 away from the front surface of the substrate 10 is sequentially provided with a first optical film 31 and a second optical film 32. A light deflecting layer 13c (i.e., a first light deflecting layer) is provided on a surface of the first optical film 31 remote from the front surface of the substrate 10; the second optical film 32 is provided with a second light deflecting layer 13d on a surface thereof remote from the front surface of the substrate 10.

By providing the first light deflecting layer 13c on the first optical film 31 and the second light deflecting layer 13d on the second optical film 32, the first and second light deflecting layers successively deflect the light emitted from the pixel unit 11, thereby obtaining a larger deflection angle. As shown in fig. 8, light rays indicated by arrows enter the first optical deflection layer 13c at an incident angle of 25 °, are deflected, enter the second optical deflection layer 13d again, are deflected again, and finally exit at a deflection angle of 75 °.

It is understood that, in this embodiment, a film layer (e.g., the optical film 121 shown in fig. 2) having a protective function may be further disposed on the second optical film 32 to protect the second light deflecting layer 13d on the second optical film 32 from being damaged.

EXAMPLE five

As shown in fig. 11 and 12, the present embodiment provides an automobile central control display screen, which includes: a driving module (not shown) and the direct display panel 100 according to the first or second to fourth embodiments, wherein the driving module is electrically connected to the direct display panel 100 to drive and control the direct display panel 100, the direct display panel 100 has the light deflection layer 13 according to the first to fourth embodiments, the light deflection layer 13 deflects the light path emitted by the pixel unit 11 of the direct display panel toward the driver, and deflects part of the reflected path of the ambient light emitted from the outside toward the direct display panel away from the driver, so as to improve the viewing effect of the viewing angle of the driver.

In one example, as shown in fig. 11, when the central control display screen is biased to the right of the driver, the deflection plane 131 in the light deflection layer is disposed to be inclined from the upper left to the lower right, i.e. to present a slope plane inclined to the right, the LED light a emitted from the pixel unit 11 will be deflected to the left by the deflection plane 131 by a certain angle, since the refractive index of the LED light a in the light-transmitting encapsulating layer 12 is greater than that in the air, when the LED light a is emitted from the deflection plane of the light-transmitting encapsulating layer to the air, the light is emitted from the light-tight medium to the light-sparse medium, so that the refractive angle is greater than the incident angle, the LED light a emitted from the deflection plane 131 will be biased to the viewing position of the left driver, thereby increasing the display brightness of the viewing position, enhancing the display effect, and simultaneously, the reflection path of a part of the ambient light F emitted from the outside to the central control display screen can be deviated from the viewing direction of the driver, the reflected light of the ambient light F deviates from the viewing position, the reflection effect of the viewing angle is reduced, and the viewing experience of a driver is improved.

In another example, as shown in fig. 12, when the central control display screen is biased to the left of the driver, the deflection surface 131 in the light deflection layer 13 is set to be inclined from the lower left to the upper right, that is, a slope plane inclined to the left is presented, the LED light a emitted by the pixel unit 11 is deflected to the right by a certain angle by the deflection surface 131, so as to increase the display brightness of the viewing position, improve the display effect, and simultaneously, the reflection path of the ambient light F incident from the outside can be biased from the viewing direction of the driver, so that the reflected light of the ambient light F is biased from the viewing position, reduce the reflection effect of the viewing angle, and improve the viewing experience of the driver. In this embodiment, the included angle between each of the deflecting surfaces 131 constituting the optical deflecting layer and the front surface of the substrate 10 may be flexibly set according to the requirement of the deflection angle of light in practical application, and the different included angles between the deflecting surfaces 131 and the front surface of the substrate 10 may result in different deflection angles of light.
