In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.
[0035] The present invention provides Figure 1-2 Embodiment 1, as Figure 3-4 Embodiment 2, Figure 5-6 Example 3 and Figure 7-8 The bending-resistant optoelectronic semiconductor display panel shown in Example 4 includes a circuit substrate 100, a plurality of curing colloids 300, and a plurality of luminous bodies 200 disposed on the circuit substrate 100. The circuit substrate 100 has a conductive circuit 400, a plurality of conductive contacts 410, and a first surface 110 and a second surface 120 opposite to each other. The conductive circuit 400 is disposed on the first surface 110 and connected to the conductive contacts 410. The conductive contacts 410 are disposed on the first surface 110 and connected to the electrode contacts 210 of the luminous bodies 200. The curing colloid 300 The first surface 110 and the light emitting body 200 are connected; the first surface 110 faces the light emitting direction of the plurality of light emitting bodies 200 and is concave-convex, so that the optoelectronic semiconductor display panel has a plurality of first blocks 500 and a plurality of second blocks 600, the first block 500 includes a supporting area 111 of a circuit substrate 100 supporting the light emitting body 200, the corresponding light emitting body 200 and the corresponding curing colloid 300, the thickness of the first block 500 is greater than the thickness of the second block 600, and the first block 500 is located between two adjacent second blocks 600.
[0036] The first surface 110 of the circuit substrate 100 is provided with a conductive circuit 400 and a plurality of conductive contacts 410 connected to the conductive circuit 400. A plurality of light-emitting bodies 200 are distributed, preferably in a matrix distribution, and fixedly arranged on the circuit substrate 100, and the electrode contacts 210 of the plurality of light-emitting bodies 200 are respectively electrically connected to the plurality of conductive contacts 410. The electrical connection method between the electrode contacts 210 of the light-emitting body 200 and the conductive contacts 410 is, for example, reflow soldering. An external control system is electrically connected to the conductive circuit 400 for controlling the light emission of the plurality of light-emitting bodies 200 so that the optoelectronic semiconductor display panel emits light and displays patterns. The light-emitting body 200 is, for example, an LED chip or an LED chip package; the circuit substrate 100 is light-transmissive and bendable, and its base material is, for example, transparent and bendable polyimide, polyethylene terephthalate, polycarbonate, glass, etc. The conductive circuit 400 can be provided on the first surface 110 of the circuit substrate 100 by, but not limited to, printing a conductive paste and then curing it; the curing colloid 300 connects the first surface 110 of the circuit substrate 100 and the light-emitting body 200 by, but not limited to, curing after dispensing, so as to strengthen and fix the light-emitting body 200 on the first surface 110, and the material of the curing colloid 300 can be, but not limited to, one of epoxy resin, polyurethane, and silicone.
[0037] By setting the first surface 110 of the circuit substrate 100 to face the light emitting direction of the plurality of light emitting bodies 200 and to be concave-convex, the optoelectronic semiconductor display panel has a plurality of first blocks 500 and a plurality of second blocks 600; since the thickness of the first block 500 located between two adjacent second blocks 600 is greater than the thickness of the second block 600, when the optoelectronic semiconductor display panel is bent, the second block 600 with a relatively thin thickness forms an easy-to-bend area, including the bearing area 111 of the circuit substrate 100 bearing the light emitting bodies 200, the bearing area 112 of the circuit substrate 100 bearing the light emitting bodies 200, and the second block 600 of the circuit substrate 100 bearing the light emitting bodies 200. The corresponding light emitting body 200 and the first block 500 of the corresponding curing colloid 300 are not easily bent, so that the light emitting body 200 installed in the first block 500 is located in the non-bending area, and the electrode contact 210 of the light emitting body 200 and the conductive contact 410 electrically connected thereto are also located in the non-bending area, thereby avoiding the connection between the electrode contact 210 and the conductive contact 410 of the light emitting body 200 becoming loose or broken due to the bending of the display panel, thereby solving the problem that the quality of the optoelectronic semiconductor display panel is easily damaged when bent.
[0038] In this article, “several” means more than 1.
[0039] Preferably, providing Figure 1-2 In the bendable optoelectronic semiconductor display panel shown in Example 1, the second surface 120 of the circuit substrate 100 is planar, and the planar second surface 120 is easy to be attached to an external carrier, for example, the optoelectronic semiconductor display panel is easy to be attached to an external transparent carrier with its back side, the first surface 110 forms a plurality of protrusions 111a, the supporting area 111 of the first block 500 is the protrusions 111a, and the plurality of light-emitting bodies 200 are respectively distributed on the plurality of protrusions 111a; the number of the plurality of conductive contacts 410 and the plurality of curing colloids 300 are both adapted to the number of the plurality of light-emitting bodies 200, the conductive contacts 410 are arranged on the protrusions 111a and connected to the electrode contacts 210 of the light-emitting bodies 200; the curing colloid 300 is located on the protrusions 111a, connecting the protrusions 111a and the light-emitting bodies 200.
[0040] Since the first surface 110 of the circuit substrate 100 forms a plurality of protrusions 111a and the second surface 120 is planar, and the plurality of luminous bodies 200 are respectively distributed on the plurality of protrusions 111a, the thickness of the first block 500 including the protrusions 111a, the corresponding luminous bodies 200 and the corresponding curing colloid 300 is greater than the thickness of the non-protruding block on the first surface 110 of the circuit substrate 100, i.e., the second block 600; when the optoelectronic semiconductor display panel is bent, the second block 600 with a relatively thin thickness forms an easy-to-bend area, and the first block 500 is thinner than the first block 500. 00 is located between the two second blocks 600, and the first block 500 including the protrusion 111a, the corresponding light-emitting body 200 and the corresponding curing colloid 300 is not easily bent, so that the light-emitting body 200 mounted on the protrusion 111a is located in the non-bending area, and the electrode contact 210 of the light-emitting body 200 and the conductive contact 410 electrically connected thereto are also located in the non-bending area, thereby avoiding the occurrence of damage to the quality of the optoelectronic semiconductor display panel caused by loosening or breaking of the connection between the electrode contact 210 and the conductive contact 410 of the light-emitting body 200 due to bending.
[0041] Among them, the number of the plurality of conductive contacts 410 and the number of curing colloids 300 are adapted to the number of the plurality of light-emitting bodies 200, which means that the original design purpose is that the number of the plurality of conductive contacts 410 and the number of curing colloids 300 are set according to the number of the plurality of light-emitting bodies 200 and are used in combination with each other.
[0042] Preferably, providing Figure 3-4 In the bendable optoelectronic semiconductor display panel shown in Example 2, the second surface 120 of the circuit substrate 100 is concave-convex following the concave-convex shape of the first surface 110, the first surface 110 forms a plurality of depressions 111b, the bearing area 111 of the first block 500 is the depression 111b, and the plurality of light-emitting bodies 200 are respectively distributed in the plurality of depressions 111b; the number of the plurality of conductive contacts 410 and the plurality of curing colloids 300 are both adapted to the number of the plurality of light-emitting bodies 200, the conductive contacts 410 are arranged in the depressions 111b and connected to the electrode contacts 210 of the light-emitting bodies 200; the curing colloid 300 connects the depressions 111b and the light-emitting bodies 200.
[0043] Since the second surface 120 of the circuit substrate 100 follows the concavo-convex shape of the first surface 110 and is concavo-convex, that is, the circuit substrate 100 is bent as a whole to form a concavo-convex shape, and the plurality of light emitters 200 are respectively distributed in the plurality of depressions 111b formed on the first surface 110 in a one-to-one correspondence, the thickness of the first block 500 including the depressions 111b, the corresponding light emitters 200, and the corresponding curing colloid 300 is greater than the thickness of the non-concave block on the first surface 110 of the circuit substrate 100, that is, the second block 600; the second surface 120 follows the concavo-convex shape of the first surface 110 and is in a concavo-convex structure, which makes it easy for the first surface 110 to be attached to an external carrier, for example, making it easy for the optoelectronic semiconductor display panel to be attached to an external carrier with its front side. The first block 500 is located between the two second blocks 600, and the first block 500 including the recess 111b, the corresponding light-emitting body 200 and the corresponding curing colloid 300 is not easily bent, so that the light-emitting body 200 arranged in the recess 111b is located in the non-bending area, and the electrode contact 210 of the light-emitting body 200 and the conductive contact 410 electrically connected thereto are also located in the non-bending area, thereby avoiding the situation in which the quality of the optoelectronic semiconductor display panel is damaged due to loosening or breaking of the connection between the electrode contact 210 and the conductive contact 410 of the light-emitting body 200 due to bending.
[0044] Preferably, if Figure 3-4 As shown in Embodiment 2, the solidified colloid 300 is located in the recess 111 b , the upper surface of the solidified colloid 300 faces the light emitting direction of the light emitting body 200 , and the upper surface of the solidified colloid 300 is flush with the light emitting surface of the light emitting body 200 .
[0045] Since there is a difference in refractive index between the solidified colloid 300 and the light-emitting surface of the light-emitting body 200 and the air, by setting the upper surface of the solidified colloid 300 to be flush with the light-emitting surface of the light-emitting body 200, the light is directly emitted into the air after being emitted from the light-emitting surface of the light-emitting body 200, thereby reducing light loss and improving the light-emitting efficiency of the light-emitting body 200. In addition, this structure will enable the solidified colloid 300 to be combined with the surface of the recess 111b to the greatest extent, thereby enhancing the overall structural strength of the first block 500.
[0046] Preferably, providing Figure 5-6 The optoelectronic semiconductor display panel shown in the third embodiment includes a circuit substrate 100, a plurality of curing colloids 300 and a plurality of luminous bodies 200, most of which are similar to those in the second embodiment. Figure 5-6As shown, the circuit substrate 100 is the same as the second embodiment: the second surface 120 of the circuit substrate 100 follows the concavo-convex shape of the first surface 110 and is concavo-convex, and the first surface 110 forms a plurality of depressions 111b; the difference is that in the third embodiment, the depressions 111b are strip-shaped, and a plurality of light emitters 200 are arranged in a rectangular array on the circuit substrate 100, and the formed plurality of rows of light emitters 220 are respectively distributed in a plurality of strip-shaped convexities 111b, and the solidified colloid 300 connects the strip-shaped depressions 111b and the light emitters 200. Among them, the length and width of the strip-shaped depressions 111b are set according to the length and width of the light emitter rows 220, so that the entire row of light emitter rows 220 is arranged in the strip-shaped depressions 111b.
[0047] Since the second surface 120 of the circuit substrate 100 follows the concavo-convex shape of the first surface 110 and is concavo-convex, and the rows of light-emitting body rows 220 are respectively distributed in the strip-shaped recesses 111b formed on the first surface 110 in a one-to-one correspondence, the interval area between two adjacent parallel strip-shaped recesses 111b on the circuit substrate 100 forms a second block 600, and the thickness of the first block 500 including the bearing area 111 (i.e., the strip-shaped recess 111b), the corresponding light-emitting body row 220 and the corresponding curing colloid 300 is greater than the thickness of the second block 600. Therefore, similar to the above, the second block 600 with a thinner thickness forms an easy-to-bend area, and the first block 500 located between the two second blocks 600 forms a non-bending area, thereby preventing the connection between the electrode contact 210 and the conductive contact 410 of the light-emitting body 200 from loosening or breaking due to bending, thereby damaging the quality of the optoelectronic semiconductor display panel.
[0048] In addition, each row of light-emitting bodies 220 is correspondingly arranged in each strip-shaped recess 111b. Compared with the solution in Example 2 in which each light-emitting body 200 is correspondingly arranged in each recess 111b, the processing complexity and difficulty of the circuit substrate 100 are reduced, the structure is simpler, and the optoelectronic semiconductor display panel is suitable for bending along the width direction of the long strip recess 111.
[0049] The light-emitting body row 220 is composed of a plurality of light-emitting bodies 200 ; the “plurality” mentioned herein means greater than 1.
[0050] Preferably, if Figure 3-4 Example 2 and Figure 5-6 As shown in Example 3, the recess 111b is a quadrangular pyramid structure; the bottom surface of the recess 111b supports the light emitting body 200, and the area of the opening of the recess 111b is larger than the area of the bottom surface, and the plane where the opening of the recess 111b is located is parallel to the bottom surface.
[0051] By designing the recess 111b to be a quadrangular pyramid structure and the opening area of the recess 111b is larger than the area of the bottom surface, the structure of being wide at the top and narrow at the bottom facilitates the light emitting body 200 to enter the recess 111b through the opening of the recess 111b and be installed, which is convenient for use. Figure 5-6 As shown in the third embodiment, the optoelectronic semiconductor display panel is provided with a strip-shaped recess 111b of a quadrangular pyramid structure. During the printing process, the conductive circuit 400 can be printed on the flat bottom surface of the strip-shaped recess 111b, which is easy to handle.
[0052] Preferably, if Figure 3-4 As shown in Example 2, the two cross sections of the recess 111b cut along the width and length directions of the circuit substrate 100 are both isosceles trapezoids, and the angle θ between the waist and the lower base of the isosceles trapezoid is 1 The angle is 120°. By setting the angle θ between the waist and the lower base of the isosceles trapezoid 1 The angle is 120°, which limits the opening size of the recess 111b, ensuring that when the light-emitting body 200 is installed in the recess 111b, the opening of the recess 111b provides sufficient space for the light-emitting body 200 to pass through, making it easy for the light-emitting body 200 to be placed and installed.
[0053] This article provides Figure 4 What is shown is a cross section along the width direction of the circuit substrate 100. It should be understood that the cross section of the recess 111b cut along the length direction of the circuit substrate 100 is similar to the cross section along the width direction of the circuit substrate 100. Both are isosceles trapezoids and the angle θ1 between the waist and the lower base of the isosceles trapezoid is 120°. Therefore, the illustration of the cross section cut along the length direction of the circuit substrate 100 is no longer provided.
[0054] Preferably, if Figure 1-2 Embodiment 1, Figure 3-4 As shown in Example 2, Figure 5-6 Example 3 and Figure 7-8 As shown in Embodiment 4, the upper surface of the solidified colloid 300 faces the light emitting direction of the light emitting body 200 , and the upper surface of the solidified colloid 300 is not higher than the light emitting surface of the light emitting body 200 .
[0055] Since there is a refractive index difference between the solidified colloid 300 and the light-emitting surface of the light-emitting body 200 and the air, by setting the upper surface of the solidified colloid 300 not higher than the light-emitting surface of the light-emitting body 200, the light is directly emitted into the air after being emitted from the light-emitting surface of the light-emitting body 200, thereby reducing light loss and improving the light-emitting efficiency of the light-emitting body 200.
[0056] Preferably, providing Figure 7-8The bending-resistant optoelectronic semiconductor display panel shown in Example 4 includes a circuit substrate 100, a plurality of curing colloids 300 and a plurality of light-emitting bodies 200, most of which are similar to those in the above-mentioned Example 1. Figure 7-8 As shown, the circuit substrate 100 is the same as in Example 1: the second surface 120 of the circuit substrate 100 is planar and the first surface 110 forms a plurality of protrusions 111a, the difference being that in this Example 4, the protrusions 111a are strip-shaped, and a plurality of light emitters 200 are arranged in a rectangular array on the circuit substrate 100, and a plurality of rows of light emitter rows 220 are formed, which are respectively distributed on a plurality of strip-shaped protrusions 111a, and the solidified colloid 300 connects the strip-shaped protrusions 111a and the light emitters 200. Among them, the length and width of the strip-shaped protrusions 111a are set according to the length and width of the light emitter rows 220, so that the entire row of light emitter rows 220 is arranged on the top surface of the strip-shaped protrusions 111a.
[0057] Since the second surface 120 of the circuit substrate 100 is planar and the first surface 110 forms a plurality of strip-shaped protrusions 111a, the plurality of rows of light-emitting body rows 220 are respectively distributed on the plurality of strip-shaped protrusions 111a in a one-to-one correspondence, and the interval area between two adjacent parallel strip-shaped protrusions 111a on the circuit substrate 100 forms a second block 600, and the thickness of the first block 500 including the bearing area 111 (i.e., the strip-shaped protrusions 111a), the corresponding light-emitting body rows 220, and the corresponding curing colloid 300 is greater than the thickness of the second block 600. Therefore, similar to the above, the second block 600 with a relatively thin thickness forms an easy-to-bend area, and the first block 500 located between the two second blocks 600 forms a non-bending area, thereby preventing the connection between the electrode contact 210 and the conductive contact 410 of the light-emitting body 200 from loosening or breaking due to bending, thereby damaging the quality of the optoelectronic semiconductor display panel.
[0058] In addition, each row of light-emitting bodies 220 is correspondingly arranged on each strip-shaped protrusion 111a. Compared with the solution in Example 1 in which each light-emitting body 200 is correspondingly arranged on each protrusion 111a, the processing complexity and difficulty of the circuit substrate 100 are reduced, the structure is simpler, and the optoelectronic semiconductor display panel is suitable for bending along the width direction of the strip-shaped protrusion 111a.
[0059] Preferably, if Figure 1-2 Embodiment 1, Figure 7-8 As shown in Example 4, the protrusion 111a is a quadrangular pyramid structure; the top surface of the protrusion 111a supports the light-emitting body 200, and the area of the top surface of the protrusion 111a is smaller than the area of the bottom of the protrusion 111a, and the top surface of the protrusion 111a is parallel to the plane where the bottom is located.
[0060] By setting the protrusion 111a to be a quadrangular pyramid structure and the area of the top surface thereof is smaller than the area of the bottom surface, when the optoelectronic semiconductor display panel is bent, the connection between the protrusion 111a of the quadrangular pyramid structure and the non-protrusion area on the first surface 110 of the circuit substrate 100 is stable, and has a stabilizing and reinforcing effect similar to a triangular reinforcing rib; in addition, if Figure 7-8 As shown in Embodiment 4, the conductive circuit 400 can be printed on the top surface of the flat strip-shaped protrusion 111 a, which is easy to handle.
