Description

Technical Field

[0001] The present invention relates to a light-emitting component and a display device including the same, and more specifically, to a light-emitting component capable of improving vertical light-emitting characteristics and a display device including the same. Background Technology

[0002] Figure 1 This is a schematic diagram used to illustrate existing light-emitting components.

[0003] Reference Figure 1 The existing light-emitting component 10 has multiple engraved light-emitting patterns 15 on one side. The light-emitting patterns 15 have a cross-section in the shape of a pillar or trench.

[0004] In order to protect the multiple light-emitting patterns 15 of such light-emitting components 10 with adhesive protective film, when the adhesive protective film is laminated on one side (pattern side) of the light-emitting component 10, due to the cross-sectional structural characteristics of the light-emitting pattern 15, the soft adhesive layer 20 in the adhesive protective film, which is like foam material, can easily fill the pattern into the engraved pattern.

[0005] In such cases, a portion of the light-emitting pattern 15 is embedded in the adhesive layer 20, resulting in a reduction in the size of the light-emitting pattern 15, or the entire light-emitting pattern 15 is embedded in the adhesive layer 20.

[0006] In addition, such as Figure 2 As shown, when the refractive index of the adhesive layer 20 is the same as or similar to that of the light-emitting component 10, if part or all of the light-emitting pattern 15 is embedded in the adhesive layer 20, the refractive index between the light-emitting component 10 and the adhesive layer 20 will be almost identical. This will cause the total internal reflection effect that occurs at the interface when the refractive index difference between the media is large to disappear. Therefore, the light-emitting pattern 15 cannot extract light.

[0007] Although existing light-emitting patterns also have inclined surfaces, when the bottom surface of the engraved pattern has a non-sharp and flat surface, it hinders the formation of the light-emitting angle of the light-emitting component mainly in the vertical direction.

[0008] Furthermore, if the shape of the emitted light pattern in the top view deviates from the arc or elliptical arc shape, the incident light rays caused by the configuration / radiation angle of the light source cannot be sufficiently mixed in multiple directions, resulting in the so-called "searchlight phenomenon (glare phenomenon)". Summary of the Invention

[0013] Technical solutions for solving the problem

[0014] According to an embodiment of the present invention, a light-emitting component includes: a side surface; a side surface having a plurality of light-emitting patterns formed thereon; and another side surface from which light is reflected and / or refracted from the plurality of light-emitting patterns is emitted; wherein the light-emitting pattern is an engraved pattern corresponding to a portion of a cone having a bottom surface and a predetermined depth, the bottom surface of the light-emitting pattern is fan-shaped, the central angle of the bottom surface of the light-emitting pattern is more than 90 degrees and less than 360 degrees, the cross-section of the light-emitting pattern has a right-angled triangle or an isosceles triangle shape, and the cross-section is a surface cut through the center of the bottom surface in a direction perpendicular to the side surface.

[0040] The following description refers to the accompanying drawings, which provide a detailed description of preferred embodiments of the present invention. It should be noted that reference numerals and identical constituent elements are used as much as possible, even in different drawings. Furthermore, when describing the present invention, detailed descriptions of related well-known functions or structures are omitted if it is determined that such detailed descriptions may unnecessarily obscure the spirit of the invention.

[0041] Figure 3 This is a plan view of the light-emitting component 100 according to an embodiment of the present invention. Figure 4 Is Figure 3 The cross-sectional view along the A-A' direction shown in the figure. Figure 5 This is just an explanation Figure 3 and Figure 4 The diagram shows a three-dimensional view of the light-emitting pattern 150, as well as a schematic diagram of its base shape and cross-sectional shape.

[0042] Reference Figures 3 to 5As shown, the light-emitting component 100 according to an embodiment of the present invention is a plate-shaped component with a predetermined thickness.

[0043] The light-emitting component 100 can be made of a light-transmitting material.

[0044] The light-emitting component 100 can be made of a rigid or flexible material. For example, the light-emitting component 100 can be made of resin or polymethyl methacrylate (PMMA).

[0045] The light-emitting component 100 has a surface 110 (or a patterned surface). A plurality of light-emitting patterns 150 are formed on the surface 110.

[0046] Multiple light-emitting patterns 150 can be arranged regularly or randomly.

[0047] The light-emitting component 100 has another side 130 (or light-emitting surface). Light reflected or refracted by the other side 130 in the light-emitting pattern 150 is emitted.

[0048] The light-emitting component 100 has multiple sides disposed between one side 110 and another side 130. Among the multiple sides, one side 120 can serve as the incident surface for light from the light source 1000.

[0049] The light-emitting pattern 150 is an intaglio pattern. The light-emitting pattern 150 can also be referred to as a cavity. The light-emitting pattern 150 may have a shape corresponding to a portion of a cone.

[0050] The bottom surface 151 of the light-emitting pattern 150 is fan-shaped. The arc portion of the fan-shaped bottom surface 151 is configured to face one side 120. Because the arc portion is configured to face one side 120, the other side 130, which serves as the light-emitting surface, has the advantage of not experiencing a searchlight effect (glare). The bottom surface 151 is disposed on the same plane as one side 110.

[0051] The central angle θ1 of the fan-shaped base 151 can be 90 degrees.

[0052] The cross section 153 of the light-emitting pattern 150 is a right-angled triangle. Specifically, the cross section 153 is a surface that cuts through the center of the fan-shaped base 151 of the light-emitting pattern 150 perpendicularly to a face 110.

[0053] The inclination angle θ2 of the cross section 153 of the right triangle can be between 50 and 60 degrees. Preferably, the inclination angle θ2 can be between 52 and 56 degrees. More preferably, the inclination angle θ2 can be 54 degrees.

[0054] The radius d1 of the fan-shaped base 151 can be smaller than the height d2 of the right-angled triangle cross section 153. The height d2 can also be referred to as the depth of the light-emitting pattern 150.

[0055] Figures 6 to 9 This is an explanation Figure 5 A perspective view, a schematic diagram of the bottom shape and the cross-sectional shape of various variations of the light-emitting pattern 150 shown.

[0056] Figure 6 The light-emitting pattern 150' shown is... Figure 5 Compared to the light-emitting pattern 150 shown, there is a difference in the central angle θ1' of the fan-shaped bottom surface 151'. The central angle θ1' is 120 degrees.

[0057] Figure 7 The light-emitting pattern 150'' shown is... Figure 5 Compared to the light-emitting pattern 150 shown, there is a difference in the central angle θ1'' of the fan-shaped bottom surface 151''. The central angle θ1'' is 180 degrees.

[0058] Figure 8 The light-emitting pattern 150''' shown is... Figure 5 Compared to the light-emitting pattern 150 shown, there is a difference in the central angle θ1''' of the fan-shaped bottom surface 151'''. The central angle θ1''' is 240 degrees.

[0059] Figure 9 The light-emitting pattern 150'''' shown is... Figure 5 Compared to the light-emitting pattern 150 shown, there is a difference in the central angle θ1'''' of the fan-shaped bottom surface 151''''. The central angle θ1'''' is 270 degrees.

[0060] include Figures 5 to 9 The light-emitting patterns 150, 150', 150'', 150''', and 150'''' shown, according to an embodiment of the present invention, have a central angle of the bottom surface of the light-emitting pattern that is 90 degrees or more and 360 degrees or less. Specifically, the central angle of the bottom surface can be 90 degrees or more and 180 degrees or more and 360 degrees or less. When the central angle of the bottom surface is less than 90 degrees, it may be disadvantageous in eliminating the spotlight effect.

[0061] Figure 10 It is a comparison from having Figures 5 to 9 A schematic diagram showing the total flux and maximum brightness of the light emitted in the display device with light emission patterns 150, 150', 150'', 150''', 150''''.

[0062] Reference Figure 10 It is known that using... Figures 5 to 9When the light-emitting components with the light-emitting patterns 150, 150', 150'', 150''', and 150'''' are shown, most of the light is well focused and emitted in the vertical center direction (vertical light emission). Therefore, the diffuser and two prism sheets in the existing backlight unit are completely removed, and only those with... Figures 5 to 9 When the light-emitting components with the light-emitting patterns 150, 150', 150'', 150''', and 150'''' are shown, they have the advantage of producing light that is almost identical to the vertically emitted light produced by existing backlight units. In addition, since the diffuser and two prism sheets used in existing backlight units can be completely removed, there is also the advantage of being able to reduce the thickness of the display device.

[0063] Figure 11 This is a plan view of the light-emitting component 200 according to another embodiment of the present invention. Figure 12 Is Figure 11 The cross-sectional view along the B-B' direction shown in the figure. Figure 13 This is just an explanation Figure 11 and Figure 12 A three-dimensional view, a schematic diagram of the bottom shape and the cross-sectional shape of the light-emitting pattern 250 shown.

[0064] Reference Figures 11 to 13 According to other embodiments of the present invention, the light-emitting component 200 is a plate-shaped component with a predetermined thickness.

[0065] The light-emitting component 200 can be made of a light-transmitting material.

[0066] The light-emitting component 200 can be made of rigid or flexible material. For example, the light-emitting component 200 can be made of resin or polymethyl methacrylate (PMMA).

[0067] The light-emitting component 200 has a surface 210 (or a patterned surface). Multiple light-emitting patterns 250 are formed on the surface 210.

[0068] Multiple light-emitting patterns 250 can be arranged regularly or randomly.

[0069] The light-emitting component 200 has another side 230 (or light-emitting surface). Light reflected or refracted by the other side 230 in the light-emitting pattern 250 is emitted.

[0070] The light-emitting component 200 has multiple side surfaces disposed between one side 210 and another side 230. Among the multiple side surfaces, one side surface 220 serves as the incident surface for light from the light source 1000.

[0071] The light-emitting pattern 250 is an intaglio pattern. The light-emitting pattern 250 can also be referred to as a cavity. The light-emitting pattern 250 may have a shape corresponding to a portion of a cone.

[0072] The bottom surface 251 of the light-emitting pattern 250 is fan-shaped. The arc portion of the fan-shaped bottom surface 251 is configured to face one side 220. Because the arc portion is configured to face one side 220, when light is incident from one side 220, the other side 230, which serves as the light-emitting surface, has the advantage of not experiencing a searchlight effect (glare). The bottom surface 251 is disposed on the same plane as one side 210.

[0073] The central angle θ3 of the bottom surface 251 of the fan-shaped structure can be between 90 degrees and 360 degrees. Specifically, the central angle θ3 of the bottom surface 251 of the fan-shaped structure can be between 90 degrees and 180 degrees, or between 180 degrees and 360 degrees.

[0074] The cross section 253 of the light-emitting pattern 250 is an isosceles triangle. Specifically, the cross section 253 is a surface that cuts through the center of the fan-shaped base 251 of the light-emitting pattern 250 perpendicularly to a surface 210.

[0075] The inclination angle θ4 of the isosceles triangle section 253 can be between 50 and 60 degrees. Preferably, the inclination angle θ4 can be between 52 and 56 degrees. More preferably, the inclination angle θ4 can be 54 degrees.

[0076] The radius d3 of the fan-shaped base 251 can be smaller than the height d4 of the isosceles triangle cross section 253. The height d4 can also be referred to as the depth of the light-emitting pattern 250.

[0077] Figure 14 and Figure 15 This is an explanation Figure 13 The diagram shows a three-dimensional view, a schematic diagram of the base shape and a schematic diagram of the cross-sectional shape of more than 250 variations of the light-emitting pattern.

[0078] Figure 14 The light-emitting pattern 250' shown is... Figure 13 Compared to the light-emitting pattern 250 shown, there is a difference in the central angle θ3' of the fan-shaped bottom surface 251'. The central angle θ3' is 180 degrees.

[0079] Figure 14 The light-emitting pattern 250'' shown is... Figure 13 Compared to the light-emitting pattern 250 shown, there is a difference in the central angle θ3'' of the fan-shaped bottom surface 251''. The central angle θ3' is 240 degrees.

[0080] Figure 16 (a) is directed towards having Figures 5 to 9 The light patterns shown are 150, 150', 150'', 150'''', 150'''' and Figures 13 to 15The photographs of the light emitting surfaces of the light emitting components 100 and 200 in the light emitting patterns 250, 250', and 250'' shown are taken when light is incident on them. Figure 16 (b) is a photograph of the light emission surface of an existing light-emitting component. Figure 16 (b) The existing light-emitting component has an engraved pattern and a trapezoidal bottom surface 5.

[0081] Reference Figure 16 (b) In the existing light-emitting component, although the bottom surface 5 of the light-emitting pattern is trapezoidal, the portion facing the incident surface is straight, thus producing a searchlight phenomenon on the light-emitting surface with a straight-line light spot that differs from other parts. However, as... Figure 16 As shown in (a), the light-emitting components 100 and 200 according to the embodiment of the present invention have a circular portion disposed on the bottom side of the light-emitting pattern toward the incident surface, thus preventing the occurrence of light emission. Figure 16 The advantages of the searchlight phenomenon on the light-emitting surface shown in (b) are illustrated.

[0082] Figure 17 (a) is a collection of Figure 4 The diagram shows a cross-sectional view of the display device with the light-emitting component 100 shown. Figure 17 (b) contains Figure 12 A cross-sectional view of the display device showing the light-emitting component 200.

[0083] Reference Figure 17 (a) According to an embodiment of the present invention, the display device may include: a light-emitting member 100 having a plurality of light-emitting patterns 150, and a light-guiding member 500 disposed on the light-emitting member 100. Although not shown separately, a reflective member may also be provided below the light-emitting member 100, and one or more light sources may be provided to provide light to one side of the light-guiding member 500 and / or one side of the light-emitting member 100.

[0084] Reference Figure 17 (b) According to another embodiment of the present invention, the display device may include: a light-emitting member 200 having a plurality of light-emitting patterns 250, and a light-guiding member 500 disposed on the light-emitting member 200.

[0086] Figure 18 The light-emitting component 300 shown in (a) also includes a component disposed in Figure 4The adhesive layer 170 on one side 110 of the light-emitting component 100 shown.

[0087] The adhesive layer 170, which is a layer coated with an adhesive substance on one side of the protective film (not shown), can be a component of the protective film (not shown). The protective film (not shown) can be laminated onto one side 110 of the light-emitting component 100 via the adhesive layer 170.

[0088] As in Figure 5 As mentioned, because the radius d1 of the bottom surface 151 of the light-emitting pattern 150 is smaller than the height d2 of the cross-section 153 of the light-emitting pattern 150, the adhesive layer 170 is difficult to be embedded into the interior of the light-emitting pattern 150. Therefore, as in Figure 2 The article mentions that the problem of existing adhesive layers being buried in the light-emitting pattern, causing light to be unable to be emitted from the light-emitting surface, can be solved.

[0089] Figure 18 The light-emitting component 400 shown in (b) also includes a component disposed in Figure 12 The adhesive layer 270 on one side 210 of the light-emitting component 200 shown.

[0090] The adhesive layer 270, which is a layer coated with an adhesive substance on one side of the protective film (not shown), can be a component of the protective film (not shown). The protective film (not shown) can be laminated onto one side 210 of the light-emitting component 200 via the adhesive layer 270.

[0091] As in Figure 13 As mentioned, because the radius d3 of the bottom surface 251 of the light-emitting pattern 250 is smaller than the height d4 of the cross-section 253 of the light-emitting pattern 250, the adhesive layer 270 is difficult to be embedded into the interior of the light-emitting pattern 250. Therefore, as in Figure 2 The article mentions that the problem of existing adhesive layers being buried in the light-emitting pattern, causing light to be unable to be emitted from the light-emitting surface, can be solved.

This indicates that, in Figure 19 In the display device of (a) (with a protective film), since the adhesive layer 170 hardly fills into the plurality of light-emitting patterns 150 of the light-emitting component 100, the light characteristics are similar to...

[0099] Figure 22 This is a cross-sectional view of a light-emitting component 900 according to another embodiment of the present invention. Figure 23 This is just an explanation Figure 22 The diagram shows a three-dimensional view of the light-emitting pattern 950, as well as a schematic diagram of its base shape and cross-sectional shape.

[0100] The light-emitting component 900 can be made of a light-transmitting material.

[0101] The light-emitting component 900 can be made of rigid or flexible material. For example, the light-emitting component 900 can be made of resin or polymethyl methacrylate (PMMA).

[0106] The cross section 953 of the light-emitting pattern 950 is an isosceles triangle. More specifically, the cross section 953 has two isosceles triangles arranged at a predetermined interval. The cross section 953 is a surface that cuts through the center of the base surface 951 perpendicularly to a face 910.

[0107] Figure 24 It has Figure 22 and Figure 23 The angular brightness distribution diagram of the display device shown is for the light-emitting component 900.

[0108] Reference Figure 24 It can be confirmed that it has Figure 22 and Figure 23 The display device with light-emitting component 900 shown focuses light well to the center.

[0109] Additionally, display devices having the light-emitting component 900, such as Figure 19 As shown in (a) and (b), a protective film (not shown) may also be included, laminated on one side 910 of the light-emitting component 900. Because the bottom surface 951 of the light-emitting pattern 950 has a circular annular shape, the adhesive layer of the protective film (not shown) is difficult to embed into the light-emitting pattern 950. Therefore, as in Figure 2 The article mentions that the problem of existing adhesive layers being buried in the light-emitting pattern, causing light to be unable to be emitted from the light-emitting surface, can be solved.

[0110] Figure 25 This is an explanation based on Figure 23 A perspective view and a schematic diagram of the bottom shape of a modified example of the light-emitting pattern 950 shown.

[0111] Figure 25 The light-emitting pattern 950' shown in the modified example, although having a circular annular shape on the bottom surface 951', is similar to... Figure 23 The light-emitting pattern 950 shown is the same, but differs in that an opening 955 is formed in a portion of the bottom surface 951'. The opening 955 makes the overall shape of the light-emitting pattern 950' similar to... Figure 23 The light emission pattern 950 shown has differences. When multiple light emission patterns 950' are formed on the light emission component by an imprinting method, an exhaust channel is formed in the opening 955 to facilitate the exhaust of air.

[0112] Figure 25 The light-emitting pattern 950' shown in the modified example also has a circular annular bottom surface 951', thus giving it the advantage that the adhesive layer with a protective film (not shown) is difficult to be buried into the light-emitting pattern.

[0113] In having Figure 25 A protective film (not shown) may also be disposed on one side of the light-emitting component of the light-emitting pattern 950' according to the modified example shown.
