Abstract
A display device comprises a first substrate, a plurality of first micro light-emitting diodes, a first upper light-transmitting protective layer and a first reflecting layer. The first micro light-emitting diode is positioned on the first substrate. The first upper light-transmitting protective layer covers the first micro light-emitting diode and has an edge structure. The width of the edge structure is gradually increased from the bottom surface of the first upper light-transmitting protection layer to the top surface of the first upper light-transmitting protection layer, so that the edge structure is provided with an inclined surface, and the inclined surface and the first substrate form an obtuse angle. The first reflective layer is disposed along the inclined surface of the edge structure. When the first micro light-emitting diode emits light, the light transmitted to the edge structure can be reflected to the upper part of the edge structure through the first reflecting layer on the inclined surface to emit light, so that the generation of lateral stray light is avoided.
Description
Technical Field
The present disclosure relates to a display device, and more particularly, to a display device having micro light emitting diodes.
Background
In recent years, flat panel display devices have been developed vigorously, and various light emitting components, such as Liquid Crystal Displays (LCDs), organic Light Emitting Diode (OLED) displays, micro light emitting diode (Micro LED, mLED) displays, and the like, are also increasingly used. The micro light emitting diode has self-luminous display characteristics, and the component has a simple structure, so that the display design with low energy consumption and high brightness can be realized.
In commercial applications, there are many larger size requirements, such as thousands of inches of display in a display field, which are achieved by means of tiled displays. In a large-sized transparent display or a non-transparent display, the problem of the appearance of the entire display at the joint is faced, for example, in a curved transparent display, the lateral stray light inside the transparent display is collected in the gap between adjacent display areas (i.e. the joint). Therefore, when the user watches the glass, the splicing bright band can be clearly observed, and the visual perception is influenced.
Disclosure of Invention
One aspect of the present disclosure is a display device.
According to some embodiments of the present disclosure, a display device includes a first substrate, a plurality of first micro light emitting diodes, a first upper transparent protection layer, and a first reflective layer. The first micro light-emitting diode is positioned on the first substrate. The first upper light-transmitting protective layer covers the first micro light-emitting diode and has an edge structure. The width of the edge structure is gradually increased from the bottom surface of the first upper light-transmitting protective layer to the top surface of the first upper light-transmitting protective layer, so that the edge structure is provided with an inclined surface, and the inclined surface and the first substrate form an obtuse angle. The first reflective layer is disposed along the inclined surface of the edge structure.
In some embodiments, the edge structure of the first upper light-transmitting protection layer extends from the edge of the first substrate without overlapping with the first substrate.
In some embodiments, the edge structure of the first upper light-transmitting protective layer is a right-angled triangular prism or an isosceles triangular prism.
In some embodiments, when the edge structure of the first upper light-transmitting protective layer is in an isosceles triangle shape, the width of the top surface of the edge structure of the first upper light-transmitting protective layer is the same as the height of the edge structure.
In some embodiments, an angle between the slope of the edge structure of the first upper light-transmitting protective layer and the top surface of the first upper light-transmitting protective layer is in a range of 22 degrees to 28 degrees or in a range of 62 degrees to 68 degrees.
In some embodiments, the first reflective layer is a metal coating, a metal plating, or a high reflective film.
In some embodiments, the display device further includes a lower light-transmissive protective layer, a lower optically transparent adhesive, and an upper optically transparent adhesive. The lower light-transmitting protective layer is positioned on the bottom surface of the first substrate. The lower optical transparent adhesive is positioned on the bottom surface of the lower light-transmitting protective layer. The upper optical transparent adhesive is positioned on the first upper light-transmitting protective layer.
In some embodiments, the display device further includes a second substrate, a plurality of second micro light emitting diodes, a second upper transparent protection layer, and a second reflective layer. The second substrate is separated from the first substrate such that a first gap is formed between the first substrate and the second substrate. The second micro light-emitting diode is positioned on the second substrate. The second upper light-transmitting protective layer covers the second micro light-emitting diode and is provided with an edge structure. The edge structure of the second upper light-transmitting protective layer and the edge structure of the first upper light-transmitting protective layer are symmetrically arranged. The second reflecting layer is arranged along the inclined plane of the edge structure of the second upper light-transmitting protective layer.
In some embodiments, a second gap is formed between the top surface of the edge structure of the first upper light-transmitting protective layer and the top surface of the edge structure of the second upper light-transmitting protective layer, and the second gap is smaller than the first gap.
In some embodiments, the first reflective layer and the second reflective layer are respectively configured to reflect light of at least one of the first micro light emitting diodes and light of at least one of the second micro light emitting diodes, so that the two lights are coupled above the first gap.
In the above embodiments of the present disclosure, since the inclined surface of the edge structure of the first upper light-transmitting protection layer forms an obtuse angle with the first substrate, and the first reflective layer is disposed along the inclined surface of the edge structure, when the first micro light-emitting diode emits light, the light transmitted to the edge structure can be reflected to the upper side of the edge structure by the first reflective layer on the inclined surface to emit light, thereby preventing the generation of side stray light. When the design is applied to a spliced display device, light rays reflected to the upper parts of the two adjacent edge structures can be guided to the same position to generate a similar light source (namely, the light coupling phenomenon of superposing the light together), so that the edge bright band phenomenon is improved, and a splicing gap is not easy to observe by human eyes. That is to say, the display device can couple the internal side stray light (flash) problem at the edge of the display area through the edge structure, so that the problem of edge bright band in the splicing gap is improved, and further the display device presents edge picture extension coupling of two adjacent display areas, thereby improving the visual experience of users.

Fig. 1 illustrates a perspective view of a display device 100 according to an embodiment of the present disclosure. As shown in the figure, the display device 100 includes a first substrate 110, a plurality of first Micro light emitting diodes 120 (Micro LEDs, mleds), a first upper light-transmissive protection layer 130, and a first reflective layer 140. The first micro light emitting diodes 120 are disposed on the first substrate 110, and the number of the first micro light emitting diodes 120 is not limited to the disclosure. The first upper light-transmitting protection layer 130 covers the first micro light-emitting diode 120, and the first upper light-transmitting protection layer 130 has an edge structure 132. The width W of the edge structure 132 increases from the bottom surface 131 of the first upper light-transmitting protection layer 130 to the top surface 133 of the first upper light-transmitting protection layer 130, so that the edge structure 132 has a slope 134. The bevel 134 of the edge structure 132 forms an obtuse angle θ 1 with the first substrate 110. In addition, the first reflective layer 140 is disposed along the slope 134 of the edge structure 132.
In some embodiments, the material of the first substrate 110 may be Polyethylene terephthalate (PET), and the material of the first upper light-transmitting protection layer 130 may be Polyvinyl butyral (PVB), but is not limited thereto. In addition, the first reflective layer 140 can be made by chemical plating, electroplating, or adhering. For example, the first reflective layer 140 may be a metal coating, a metal plating, or a highly reflective film, such as a silver coating, an aluminum-deposited coating, or a reflective film having a transmittance of 95% or more. In this embodiment, the display device 100 can be a transparent display and can be applied to the field of tiled display.
In addition, the display device 100 may further include a lower light-transmitting protective layer 150, a lower Optically Clear Adhesive (OCA) 160, and an upper optically clear adhesive 170. The lower light-transmitting protective layer 150 is located on the bottom surface of the first substrate 110. In the present embodiment, the thickness of the lower light-transmitting protective layer 150 is smaller than that of the first upper light-transmitting protective layer 130. The lower optically transparent adhesive 160 is disposed on the bottom surface of the lower light-transmitting protection layer 150, such that the lower light-transmitting protection layer 150 is disposed between the first substrate 110 and the lower optically transparent adhesive 160. The upper optically clear adhesive 170 is on the first upper light transmissive protective layer 130.
In the following description, a state in which the display device 100 operates will be described.
Fig. 2 is a schematic optical path diagram illustrating the operation of the display device 100 of fig. 1. Referring to fig. 1 and fig. 2, specifically, since the inclined surface 134 of the edge structure 132 of the first upper transparent protection layer 130 and the first substrate 110 form an obtuse angle θ 1, and the first reflective layer 140 is disposed along the inclined surface 134 of the edge structure 132, when the first micro light emitting diode 120 emits light (for example, light L1 and L3), the light L3 transmitted to the edge structure 132 can be reflected to the upper side of the edge structure 132 by the first reflective layer 140 on the inclined surface 134 to emit light, thereby preventing the generation of lateral stray light.
In addition, in some embodiments, the edge structure 132 of the first upper light-transmitting protective layer 130 extends from the edge of the first substrate 110 without overlapping the first substrate 110 in the Z-axis direction. The edge structure 132 of the first upper transparent protection layer 130 may be a right-angled triangular prism, but not limited thereto, and may also be an isosceles triangular prism (as will be described in fig. 6). The included angle θ 2 between the slope 134 of the edge structure 132 of the first upper light-transmissive protection layer 130 and the top surface 133 of the first upper light-transmissive protection layer 130 is in a range from 62 degrees to 68 degrees, such as 65 degrees, but is not limited thereto, and may also be 45 degrees (to be described in fig. 6) or 25 degrees (to be described in fig. 7).
The display device 100 may further include a structure that is the same as and adjacent to the first substrate 110, the first micro light emitting diode 120, the first upper transparent protective layer 130, the first reflective layer 140, the lower transparent protective layer 150, the lower optically transparent adhesive 160 and the upper optically transparent adhesive 170, so as to serve as a tiled display device. That is, the display device 100 further includes a second substrate 110a, a plurality of second micro light emitting diodes 120a, a second upper transparent protection layer 130a and a second reflective layer 140a. The second substrate 110a is separated from the first substrate 110 such that a first gap G1 is formed between the first substrate 110 and the second substrate 110 a. The second micro light emitting diode 120a is located on the second substrate 110 a. The second upper light-transmitting protection layer 130a covers the second micro light-emitting diode 120a, and the second upper light-transmitting protection layer 130a has an edge structure 132a. The edge structure 132a of the second upper transparent protection layer 130a and the edge structure 132 of the first upper transparent protection layer 130 are symmetrically disposed. The second reflective layer 140a is disposed along the slope 134 of the edge structure 132a of the second upper light-transmitting protective layer 130 a. In this embodiment, a second gap G2 is formed between the top surface of the edge structure 132 of the first upper light-transmitting protection layer 130 and the top surface of the edge structure 132a of the second upper light-transmitting protection layer 130a, and the second gap G2 is smaller than the first gap G1.
When the second micro light emitting diode 120a emits light (e.g., the light beams L2 and L3), the light beam L3 transmitted to the edge structure 132a can be reflected to the upper side of the edge structure 132a by the second reflective layer 140a on the inclined plane 134 to emit light, so as to avoid the generation of side stray light. The first reflective layer 140 and the second reflective layer 140a are respectively configured to reflect the light L3 of the first micro light emitting diode 120 and the light L3 of the second micro light emitting diode 120a, so that the two light L3 are coupled above the first gap G1 and the second gap G2.
Through the above design, when the display device 100 is applied to the tiled display device, the light L3 reflected to the upper side of the two adjacent edge structures 132 and 132a by the first reflective layer 140 and the second reflective layer 140a can be guided to the same position to generate the similar light source (i.e. the light coupling phenomenon of superimposing the light together), so that the edge bright band phenomenon is improved, and the tiled gap (e.g. the first gap G1 and the second gap G2) is not easy to be observed by human eyes. That is to say, the display device 100 can couple the inner side stray light (flash) problem at the edge of the display region through the edge structures 132 and 132a, so that the edge bright band problem in the splicing gap is improved, and the display device 100 presents the edge picture extension coupling of two adjacent display regions, thereby improving the visual experience of the user.
Fig. 3 is a schematic diagram illustrating that light beams L1, L2, and L3 of the display device 100 of fig. 2 respectively form light regions P1 and P2 and a coupling light region P3 in a top view direction (i.e., a Z-axis direction). Referring to fig. 2 and 3, the first micro light emitting diode 120 can emit a light L1 directly passing through the upper optical transparent adhesive 170 and a light L3 reflected by the first reflective layer 140, and the second micro light emitting diode 120a can emit a light L2 directly passing through the upper optical transparent adhesive 170a and a light L3 reflected by the second reflective layer 140a. The light L1 can form a light region P1 outside the upper optical transparent adhesive 170, the light L2 can form a light region P2 outside the upper optical transparent adhesive 170a, and the two light L3 can form a light coupling region P3 above the edge structures 132 and 132a (e.g., above the first gap G1 or above the second gap G2). The coupling light area P3 can improve the problem of edge bright band, so that the display device 100 can display edge picture extension coupling of two adjacent display areas, thereby improving the visual perception of the user.
Fig. 4 illustrates the result of the experiment of coupling light in the display device 100 of fig. 2. Referring to fig. 2 and fig. 4, the light L1 may form a light region P1 outside the upper optical transparent adhesive 170, the light L2 may form a light region P2 outside the upper optical transparent adhesive 170a, and the two light L3 may form a coupling light region P3 above the edge structures 132 and 132a (e.g., the region above the first gap G1 or the region above the second gap G2). The light L3 reflected to the upper side of the two adjacent edge structures 132,132a can be guided to the same position to generate a similar light source, such as a coupling light area P3, so that the edge bright band phenomenon is improved, and the splicing seam is not easy to observe by human eyes. In the present embodiment, the luminance maximum value of the light regions P1, P2 and the coupling light region P3 may be 3000 nit (nit).
Fig. 5 shows another light coupling experiment result of the display device 100 of fig. 2. Referring to fig. 2 and 5, when the luminance of the light regions P1 and P2 and the coupling light region P3 generated by the light lines L1, L2 and L3 is low (e.g., 500 nits), the edge bright band phenomenon is almost completely eliminated, so as to improve the visual perception of the user.
It should be understood that the connection and function of the components already described will not be repeated and will be described in detail. In the following description, other types of edge structures will be described.
Fig. 6 illustrates a perspective view of a display device 100a according to another embodiment of the present disclosure. The display device 100a includes a first substrate 110, a plurality of first micro light emitting diodes 120, a first upper transparent protection layer 130, a first reflective layer 140, a second substrate 110a, a plurality of second micro light emitting diodes 120a, a second upper transparent protection layer 130a, a second reflective layer 140a, a lower transparent protection layer 150, a lower optically transparent adhesive 160, and an upper optically transparent adhesive 170. The difference between this embodiment and the embodiment in fig. 2 is that the edge structure 132 of the first upper transparent protection layer 130 of the display device 100a is in the shape of an isosceles triangle. With this configuration, the width Wt of the top surface of the edge structure 132 of the first upper light-transmitting protective layer 130 of the display device 100a is the same as the height H of the edge structure 132. An included angle θ 3 between the inclined surface 134 of the edge structure 132 of the first upper light-transmissive protection layer 130 and the top surface 133 of the first upper light-transmissive protection layer 130 of the display device 100a is 45 degrees.

This embodiment is different from the embodiment of fig. 2 in that an included angle θ 4 between the slope 134 of the edge structure 132 of the first upper light-transmissive protection layer 130 of the display device 100b and the top surface 133 of the first upper light-transmissive protection layer 130 is in a range of 22 degrees to 28 degrees, for example, 25 degrees.
