A light emitting diode (LED) display apparatus includes a driving backplane and a plurality of LED components transposed on the driving backplane. Inheriting the characteristics of the LED, the LED display apparatus has the advantages such as saving power, high efficiency, high brightness and fast response time.

DETAILED DESCRIPTION

The present disclosure will now be described hereinafter in details with reference to the accompanying drawings, in which exemplary embodiments of the disclosure are shown. Whenever possible, identical reference numerals refer to identical or like elements in the drawings and descriptions.

It should be understood that when one component such as a layer, a film, a region or a substrate is referred to as being disposed “on” the other component or “connected to” the other component, the component may be directly disposed on the other component or connected to the other component, or an intermediate component may also exist between the two components. In contrast, when one component is referred to as being “directly disposed on the other component” or “directly connected to” the other component, no intermediate component exists therebetween. As used herein, a “connection” may be a physical and/or electrical connection. In addition, when two components are “electrically connected” or “coupled”, other components may exist between the two components.

The terms “about”, “approximately” or “substantially” as used herein shall cover the values described, and cover an average value of an acceptable deviation range of the specific values ascertained by one of ordinary skill in the art, where the deviation range may be determined by the measurement described and specific quantities of errors related to the measurement (that is, the limitations of the measuring system). For example, the term “about” represents within one or more standard deviations of a given value of range, such as within +30 percent, within +20 percent, within +10 percent or within +5 percent. Moreover, the terms “about”, “approximately” or “substantially” as used herein may selectively refer to a more acceptable deviation range or the standard deviation based on the optical characteristics, the etching characteristic or other characteristics, without applying one standard deviation to all characteristics.

Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and the present disclosure, and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

FIG. 1A to FIG. 1D are sectional schematic views of a manufacturing process of a display panel according to a first embodiment of the present disclosure.

Referring to FIG. 1A, firstly, a driving backplane 110 is provided, where the driving backplane 110 has a first pad 112 and a second pad 114 separated from each other. In detail, in one embodiment, the driving backplane 110 may include a supporting substrate (not illustrated) and a pixel driving circuit (not illustrated) disposed on the supporting substrate, and the first pad 112 and the second pad 114 are electrically connected to different ends of the pixel driving circuit respectively.

Subsequently, in one embodiment, an insulating layer 120 and, optionally, a flat layer 130 and a shielding protective layer 140 may be formed on the driving backplane 110. The insulating layer 120 is disposed on the driving backplane 110 and has a first opening 122 and a second opening 124. The first opening 122 and the second opening 124 of the insulating layer 120 respectively overlap with the first pad 112 and the second pad 114. The flat layer 130 is disposed on the insulating layer 120 and has a first opening 132 and a second opening 134. The first opening 132 and the second opening 134 of the flat layer 130 respectively overlap with the first opening 122 and the second opening 124 of the insulating layer 120. The shielding protective layer 140 is disposed on the flat layer 130 and has a first opening 142 and a second opening 144. The first opening 142 and the second opening 144 of the shielding protective layer 140 respectively overlap with the first opening 122 and the second opening 124 of the insulating layer 120.

In one embodiment, the material of the insulating layer 120 may be an inorganic material (such as silicon oxide, silicon nitride, silicon oxynitride, or a stacked layer of at least two thereof), an organic material or a combination thereof. In one embodiment, the material of the flat layer 130 may be an inorganic material (such as silicon oxide, silicon nitride, silicon oxynitride, or a stacked layer of at least two thereof), an organic material or a combination thereof. In one embodiment, the material of the shielding protective layer 140 may be an inorganic material (such as silicon oxide, silicon nitride, silicon oxynitride, or a stacked layer of at least two thereof), an organic material or a combination thereof.

Subsequently, in one embodiment, a metal oxide pattern 150 may be optionally formed on the shielding protective layer 140 to cover a portion of the second pad 114 exposed by the second opening 144 of the shielding protective layer 140 and the second opening 124 of the insulating layer 120. The metal oxide pattern 150 is used to protect the second pad 114. In one embodiment, the material of the metal oxide pattern 150 is indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, other suitable oxides, or a stacked layer of at least two thereof, but the present disclosure is not limited thereto.

Referring to FIG. 1B, subsequently, the light emitting component 160 is transferred onto the driving backplane 110, and the light emitting component 160 is electrically connected to the driving backplane 110. The light emitting component 160 includes a first semiconductor layer 161, a second semiconductor layer 162, an active layer 163 disposed between the first semiconductor layer 161 and the second semiconductor layer 162, a first electrode 164 electrically connected to the first semiconductor layer 161 and a second electrode 165 electrically connected to the second semiconductor layer 162. The first electrode 164 and the second electrode 165 of the light emitting component 160 are respectively located at two opposite sides of the active layer 163. The light emitting component 160 is a vertical light emitting diode (LED). The first electrode 164 of the light emitting component 160 is electrically connected to the first pad 112 of the driving backplane 110, and the first electrode 164 of the light emitting component 160 is located between the second electrode 165 of the light emitting component 160 and the first pad 112 of the driving backplane 110. The light emitting component 160 is disposed on the first pad 112 and overlaps with the first opening 122 of the insulating layer 120. In one embodiment, the light emitting component 160 further overlaps with the first opening 132 of the flat layer 130 and the first opening 142 of the shielding protective layer 140.

The light emitting component 160 has a peripheral surface 160a located between the first electrode 164 and the second electrode 165. In one embodiment, the light emitting component 160 further includes an insulating layer 166. The insulating layer 166 covers a side wall of the first semiconductor layer 161, a side wall of the second semiconductor layer 162 and/or a side wall of the active layer 163, and has an outer surface facing away from the side wall of the first semiconductor layer 161, the side wall of the second semiconductor layer 162 and/or the side wall of the active layer 163. The peripheral surface 160a may include the side wall of the first semiconductor layer 161, the side wall of the second semiconductor layer 162, the side wall of the active layer 163 and/or the outer surface of the insulating layer 166.

Referring to FIG. 1C, subsequently, a reflective structure 170 is formed on the driving backplane 110. The reflective structure 170 is disposed on the driving backplane 110, and is located at a periphery of the light emitting component 160. It should be noted that a portion of the light beam (not illustrated) emitted by the light emitting component 160 may be transmitted toward the peripheral surface 160a of the light emitting component 160, and the reflective structure 170 may guide the light beam transmitted toward the peripheral surface 160a to a side where the second electrode 165 is located. Thus, the light beam emitted by the light emitting component 160 may concentrate toward a normal direction (that is, the first direction z), and the light shape of the light emitting component 160 is adjusted, thereby enhancing the brightness thereof. In addition, the reflective structure 170 used to adjust the light shape may be manufactured using the existing manufacturing device, without the need to additionally purchase devices.

In one embodiment, the reflective structure 170 is disposed on the first pad 112 and may optionally cover at least one portion of the peripheral surface 160a of the light emitting component 160. In one embodiment, the reflective structure 170 may directly contact the peripheral surface 160a of the light emitting component 160. In one embodiment, the reflective structure 170 may have a first opening 172 overlapping with the light emitting component 160. In one embodiment, a portion of the reflective structure 170 may be disposed in the first opening 122 of the insulating layer 120. In one embodiment, the reflective structure 170 may directly contact the first pad 112.

In one embodiment, the reflective structure 170 has a surface 170a facing away from the driving backplane 110, and the second electrode 165 of the light emitting component 160 has a surface 165a facing away from the driving backplane 110. The first direction z is substantially perpendicular to the driving backplane 110, and a distance D_112-170a between the surface 170a of the reflective structure 170 and the first pad 112 in the first direction z is less than a distance D_112-165a between the surface 165a of the second electrode 165 and the first pad 112 in the first direction z. In other words, in one embodiment, the reflective structure 170 covers the light emitting component 160 but is not higher than the second electrode 165 of the light emitting component 160, and the reflective structure 170 may expose the second electrode 165, thus allowing the second electrode 165 to be electrically connected to the second pad 114 of the driving backplane 110 in the subsequent manufacturing process.

In one embodiment, a second direction x is substantially parallel to the driving backplane 110, and a width W₁₇₀ of the reflective structure 170 in the second direction x is greater than or equal to a width W₁₂₂ of the first opening 122 of the insulating layer 120 in the second direction x. In other words, in one embodiment, the reflective structure 170 may fully occupy the first opening 122 of the insulating layer 120 exposing the first pad 112. Thus, even though the light emitting component 160 deviates when being transferred to the driving backplane 110, since the reflective structure 170 is sufficiently wide, the reflective structure 170 may still well cover the light emitting component 160, thereby achieving good light shape adjustment and brightness enhancement effects.

The reflective structure 170 has high reflectivity. For example, in one embodiment, the reflectivity of the reflective structure 170 at the wavelength of 450 nm may be greater than 50%. Preferably, the reflectivity of the reflective structure 170 at the wavelength of 450 nm may be greater than 70%, but the present disclosure is not limited thereto.

In one embodiment, the reflective structure 170 may be optionally white, but the present disclosure is not limited thereto. In one embodiment, the material of the reflective structure 170 may include an organic material, an inorganic material, a metal or a combination thereof, but the present disclosure is not limited thereto.

In one embodiment, the reflective structure 170 has a peripheral surface 170b located around the light emitting component 160. In one embodiment, the peripheral surface 170b may include a plurality of sub-surfaces with different slopes. However, the present disclosure is not limited thereto, and the quantity and the slopes of the sub-surfaces of the peripheral surface 170b may be adjusted based on the need of the actual light shapes.

Referring to FIG. 1D, subsequently, in one embodiment, a flat layer 180 may be formed on the driving backplane 110 to cover the shielding protective layer 140 and at least one portion of the peripheral surface 170b of the reflective structure 170. In one embodiment, the flat layer 180 has a first opening 182 overlapping with the reflective structure 170. In one embodiment, the flat layer 180 has a second opening 184 overlapping with the second pad 114. In one embodiment, the second opening 184 of the flat layer 180 exposes a portion of the metal oxide pattern 150. In one embodiment, the material of the flat layer 180 may be an inorganic material (such as silicon oxide, silicon nitride, silicon oxynitride, or a stacked layer of at least two thereof), an organic material or a combination thereof.

Referring to FIG. 1D, subsequently, in one embodiment, a bridging component 190 may be formed on the flat layer 180 and the light emitting component 160. The bridging component 190 is disposed on the flat layer 180 and the light emitting component 160. One end 192 of the bridging component 190 is electrically connected to the second electrode 165 of the light emitting component 160, the bridging component 190 passes across at least one portion of the reflective structure 170, and the other end 194 of the bridging component 190 is filled in the second opening 184 of the flat layer 180 to be electrically connected to the second pad 114 of the driving backplane 110 through the metal oxide pattern 150, thus completing the display panel 10. In one embodiment, the bridging component 190 is, for example, a transparent conductive layer, which includes a metal oxide, such as indium tin oxide, indium zinc oxide, aluminum tin oxide, aluminum zinc oxide, indium germanium zinc oxide, other suitable oxides, or a stacked layer of at least two thereof, but the present disclosure is not limited thereto. It should be noted herein that the following embodiment uses the reference numerals and certain contents of the aforementioned embodiment, in which identical or similar components are identified by identical reference numerals, and descriptions of the identical technical contents will be omitted. The omitted descriptions may be referenced to in the aforementioned embodiment, and are not hereinafter reiterated in the following embodiments.

FIG. 2A to FIG. 2E are sectional schematic views of a manufacturing process of a display panel according to a second embodiment of the present disclosure. The display panel 10A and the manufacturing process thereof in the second embodiment are similar to the display panel 10 and the manufacturing process thereof in the first embodiment, and the difference between the two exists in that the reflective structure 170A in the second embodiment is different from the reflective structure 170 in the first embodiment.

Referring to FIG. 2C and FIG. 2D, in the present embodiment, a main portion 170-1 is formed on the first pad 112 and the peripheral surface 160a of the light emitting component 160. The main portion 170-1 has a peripheral surface 170-1b located around the light emitting component 160. Subsequently, an auxiliary portion 170-2 is formed at least on the peripheral surface 170-1b of the main portion 170-1. Referring to FIG. 2D, in the present embodiment, the reflective structure 170A includes the main portion 170-1 and the auxiliary portion 170-2. The main portion 170-1 is disposed on the peripheral surface 160a of the light emitting component 160, and the auxiliary portion 170-2 is disposed at least on the peripheral surface 170-1b of the main portion 170-1.

Referring to FIG. 2E, if the light beam (not illustrated) transmitted toward the peripheral surface 160a of the light emitting component 160 passes through the main portion 170-1 of the reflective structure 170A without being reflected, the auxiliary portion 170-2 may reflect the light beam passing through the main portion 170-1, thereby guiding the light beam toward the side where the second electrode 165 is located. Thus, the brightness of the display panel 10A may be further enhanced.

The material of the main portion 170-1 of the reflective structure 170A is different from the material of the auxiliary portion 170-2. For example, in one embodiment, the material of the main portion 170-1 may be a white organic material, and the material of the auxiliary portion 170-2 may be a black organic material, but the present disclosure is not limited thereto. In one embodiment, the optical density (OD) of the auxiliary portion 170-2 may be greater than or equal to 1. Preferably, the OD of the auxiliary portion 170-2 may be greater than or equal to 2, but the present disclosure is not limited thereto.

Specifically, the material of the auxiliary portion 170-2B of the reflective structure 170B in the third embodiment is different from the material of the auxiliary portion 170-2 of the reflective structure 170A in the second embodiment. In the third embodiment, the material of the auxiliary portion 170-2B of the reflective structure 170B may be metal.

The display panel 10C and the manufacturing process thereof in the fourth embodiment are similar to the display panel 10 and the manufacturing process thereof in the first embodiment, and the difference between the two exists in that the reflective structure 170C in the fourth embodiment is different from the reflective structure 170 in the first embodiment. In addition, in the fourth embodiment, the reflective structure 170C may replace the flat layer 180 in the first embodiment, and the display panel 10C in the fourth embodiment may omit the flat layer 180 of the display panel 10 in the first embodiment.

Referring to FIG. 4D, in the present embodiment, the insulating layer 120 is disposed on the driving backplane 110 and has a first opening 122 overlapping with the first pad 112 and a body 120s defining the first opening 122.

In the present embodiment, the reflective structure 170C may have a second opening 174 overlapping with the second pad 114, and the other end 194 of the bridging component 190 is filled in the second opening 174 of the reflective structure 170C to be electrically connected to the second pad 114.

The display panel 10D and the manufacturing process thereof in the fifth embodiment are similar to the display panel 10C and the manufacturing process thereof in the fourth embodiment, and the difference between the two exists in that the reflective structure 170D in the fifth embodiment is different from the reflective structure 170C in the fourth embodiment. In the fifth embodiment, the reflective structure 170D may replace the flat layer 130 and the shielding protective layer 140 of the display panel 10C in the fourth embodiment. The display panel 10D in the fifth embodiment may omit the flat layer 130 and the shielding protective layer 140 of the display panel 10C in the fourth embodiment.

FIG. 6A to FIG. 6D are sectional schematic views of a manufacturing process of a display panel according to a sixth embodiment of the present disclosure. The display panel 10E and the manufacturing process thereof in the sixth embodiment are similar to the display panel 10 and the manufacturing process thereof in the first embodiment, and the difference between the two exists in that the reflective structure 170E in the sixth embodiment is different from the reflective structure 170 in the first embodiment. In addition, as shown in FIG. 6A to FIG. 6C, in the present embodiment, the reflective structure 170E has been formed on the insulating layer 120 prior to the light emitting component 160 being transferred to the driving backplane 110.

Referring to FIG. 6D, in the present embodiment, the reflective structure 170E may be a stopping wall structure. In detail, the reflective structure 170E has a first opening 172E overlapping with the first pad 112 and the light emitting component 160. The flat layer 180 is disposed on the reflective structure 170E and filled in the first opening 172E of the reflective structure 170E.

In the present embodiment, the flat layer 180 has a high transmittance. For example, the transmittance of the flat layer 180 is preferably greater than or equal to 90%.

FIG. 7A to FIG. 7E are sectional schematic views of a manufacturing process of a display panel according to a seventh embodiment of the present disclosure. The display panel 10F and the manufacturing process thereof in the seventh embodiment are similar to the display panel 10E and the manufacturing process thereof in the sixth embodiment, and the difference between the two exists in that the reflective structure 170F in the seventh embodiment is different from the reflective structure 170E in the sixth embodiment.
