[0051] The present invention can be understood by referring to the following detailed description in conjunction with the accompanying drawings. It should be noted that, to facilitate understanding by the reader and to simplify the drawings, the various drawings in this disclosure depict only a portion of the light-emitting unit, and certain components in the drawings are not drawn to scale. Furthermore, the number and size of components in the drawings are for illustration only and are not intended to limit the scope of the present invention. Furthermore, similar and / or corresponding reference numerals may be used in different embodiments only to simplify and clarify the description of some embodiments and do not represent any relationship between the different embodiments and / or structures discussed.

[0052] Throughout the present specification and the appended claims, certain words will be used to refer to specific components. It should be understood by those skilled in the art that electronic equipment manufacturers may refer to the same components by different names. This document does not intend to distinguish between components that have the same function but different names. In the following description and claims, words such as "include", "contain", "have" are open-ended words and should be interpreted as meaning "including but not limited to..." Therefore, when the terms "include", "contain" and / or "have" are used in the description of the present invention, they specify the existence of corresponding features, areas, steps, operations and / or components, but do not exclude the existence of one or more corresponding features, areas, steps, operations and / or components.

[0053] In addition, relative terms such as "below" or "bottom" and "above" or "top" may be used in the embodiments to describe the relative relationship of one element to another element in the drawings. It is understood that if the device in the drawings is turned upside down, the element described as being on the "below" side will become the element on the "above" side.

[0054] When a component (such as a layer or region) is referred to as being "on" another component, it can be directly on the other component or there can be other components between the two components. On the other hand, when a component is referred to as being "directly on" another component, there are no components between the two components. In addition, when a component is referred to as being "on" another component, the two components have a top-to-bottom relationship in a top-down view, and the component can be above or below the other component, depending on the orientation of the device.

[0055] It is understood that although the terms "first", "second", etc. may be used herein to describe various elements, layers and / or parts, these elements, layers and / or parts should not be limited by these terms, and these terms are only used to distinguish different elements, layers and / or parts. Therefore, a first element, layer and / or part discussed below may be referred to as a second element, layer and / or part without departing from the teachings of some embodiments of the present invention. In addition, for the sake of brevity, the terms "first", "second", etc. may not be used in the specification to distinguish different elements. Without violating the scope defined by the appended claims, the first element and / or second element recorded in the claims may be interpreted as any element that meets the description in the specification.

[0056] In the present invention, length, width, and / or thickness can be measured using an optical microscope or from cross-sectional images obtained through an electron microscope. However, these measurement methods are provided as examples only and are not intended to limit the present invention. Furthermore, any two values ​​or directions used for comparison may have a certain degree of error. The terms "approximately," "equal," "equal," "same," "substantially," or "substantially" are generally interpreted as meaning within 20% of the given value, or within a range of 10%, 5%, 3%, 2%, 1%, or 0.5% of the given value. Furthermore, the term "electrically connected" may be used below. It should be understood that when the present invention states that "a first element is electrically connected to a second element," this can be interpreted as meaning that the first and second elements are electrically connected and can be synchronously controlled by a single operation. This can include situations where another element is present between the first and second elements to electrically connect them, or situations where the first and second elements are directly electrically connected without any other element present between them. When a first element is referred to herein as being "directly electrically connected" to a second element, this refers to a situation where the first and second elements are "directly electrically connected, with no other element interposed between them." Furthermore, the term "electrically isolated" may be used below. It should be understood that when the present invention states that "a first element is electrically isolated from a second element," this can be interpreted as meaning that the first and second elements are electrically separated, not interconnected, and not synchronously controlled by a single operation.

[0057] It should be noted that the technical solutions provided in the following different embodiments can be replaced, combined or mixed with each other to form another embodiment without violating the spirit of the present invention.

[0058] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It is understood that these terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with the background or context of the relevant art and the present invention and should not be interpreted in an idealized or overly formal manner unless specifically defined herein.

[0059] Figure 1A schematic top view of a display device 10 according to some embodiments of the present invention is shown. The display device 10 may, for example, include a backlight device, an antenna device, a light-emitting device, a sensor device, a touch device, or a splicing device, but is not limited thereto. The display device 10 may be a bendable or flexible electronic device. The display device may be a non-luminous display device or a self-luminous display device. The antenna device may be a liquid crystal antenna device or a non-liquid crystal antenna device, and the sensor device may be a sensor device that senses capacitance, light, heat, or ultrasound, but the present invention is not limited thereto. In some embodiments, the display device 10 includes a flexible panel, which includes electronic components. The electronic components may include passive and active components, such as capacitors, resistors, inductors, diodes, transistors, etc. In some embodiments, the electronic device may include, for example, a diode, liquid crystal, a light-emitting diode (LED), a quantum dot (QD), fluorescence, phosphor, other suitable display media, or a combination thereof. In some embodiments, the diode may include a light-emitting diode or a photodiode. The light emitting diode may, for example, include an organic light emitting diode (OLED), a sub-millimeter light emitting diode (mini LED), a micro LED or a quantum dot light emitting diode (quantum dot LED), but the present invention is not limited thereto. The splicing device may, for example, be a display splicing device or an antenna splicing device, but the present invention is not limited thereto. It should be noted that the display device 10 may be any of the aforementioned arrangements and combinations, but is not limited thereto. In addition, the shape of the display device 10 may be rectangular, circular, polygonal, a shape with curved edges or other suitable shapes. The display device 10 may have peripheral systems such as a drive system, a control system, a light source system, etc. to support the display device, antenna device, wearable device (for example, including augmented reality or virtual reality), vehicle-mounted device or splicing device.

[0060] The following paragraphs will describe the present invention with respect to a partial structure of the display device 10, but the present invention is not limited thereto. Those skilled in the art will appreciate that the display device 10 may also include other structures or be equipped with suitable electronic components to perform the intended functions.

[0061] like Figure 1As shown, the display device 10 may include a backlight module 100 and a display panel 200 located above the backlight module 100. This embodiment only schematically illustrates the approximate positions of the backlight module 100 and the display panel 200. The detailed structures of the backlight module 100 and the display panel 200 will be further described below. In some embodiments, the display panel 200 may have an active area 201. Specifically, the active area 201 may be an area on the display panel 200 that can be operated by a user, but the present invention is not limited to this. In some embodiments, the active area 201 may be an area on the display panel 200 that can display information to the user (i.e., the user's visible area).

[0062] Figure 2 A partial perspective schematic diagram of a display device 10 according to some embodiments of the present invention is shown. For example, Figure 2 Can be along Figure 1 The display device 100 is shown along line AA, but the present invention is not limited thereto. It should be noted that in order to focus on the structure of the backlight module 100 in this embodiment, the display panel 200 is not shown. In some embodiments, the backlight module 100 may include a backplate 110, a circuit substrate 120, a plurality of optical elements 130, a diffuser 140, and at least one optical film 150. In some embodiments, the circuit substrate 120 is, for example, disposed on and supported by the backplate 110. In some embodiments, the circuit substrate 120 overlaps or corresponds to at least a portion of the backplate 110 in a normal direction (e.g., substantially parallel to the Z-axis) of the display device 10. The optical element 130 is, for example, disposed on the circuit substrate 120 and electrically connected to the circuit substrate 120. In this way, the circuit substrate 120 can supply power to the optical element 130, so that the optical element 130 can emit light to display information. In some embodiments, the light-emitting element 130 may be a light-emitting diode (LED), including an organic light-emitting diode (OLED), a sub-millimeter light-emitting diode (mini LED), a micro LED, or a quantum dot LED, but the present invention is not limited thereto. In some embodiments, the circuit substrate 120 may be a printed circuit board (PCB), a flexible printed circuit (FPC), or the like, but the present invention is not limited thereto.

[0063] In some embodiments, the back panel 110 may have a bottom surface 111 and sidewalls 112 perpendicular to the bottom surface 111. In some embodiments, the circuit substrate 120 may rest on the bottom surface 111 of the back panel 110, while the optical element 130 is disposed above the bottom surface 111 of the back panel 110. In some embodiments, the sidewalls 112 of the back panel 110 may be provided with a support portion 113 to support the diffuser plate 140, thereby reducing the risk of the diffuser plate 140 and the optical film 150 falling. In some embodiments, the optical film 150 may include, for example, a lower diffuser film, an upper diffuser film, a lower brightness enhancement film, an upper brightness enhancement film, or a prism film, but the present invention is not limited thereto. In some embodiments, the optical film 150 may include, for example, an inverse prism film, which is used, for example, to focus light, but the present invention is not limited thereto. In some embodiments, an adhesive (not shown) may be provided between the optical film 150 and the diffuser plate 140 to affix the optical film 150 to the diffuser plate 140, thereby simplifying the assembly process. For example, the structure of this embodiment can be applied to the upper and lower sides of the display device 10, but the present invention is not limited thereto.

[0064] Figure 3 A partial perspective schematic diagram of a display device 10 according to some embodiments of the present invention is shown. For example, Figure 3 Can be along Figure 1 The diagram is shown by the line BB, but the present invention is not limited thereto. Figure 3 As shown, the backlight module 100 may include a support pin 160, which is arranged above the circuit substrate 120 and adjacent to the light-emitting element 130. The support pin 160 can be used to support the diffuser plate 140 and the optical film 150. In some embodiments, the support pin 160 may be in contact with the diffuser plate 140 (that is, the distance between the support pin 160 and the diffuser plate 140 is 0), but the present invention is not limited to this. In some embodiments, the gap between the support pin 160 and the diffuser plate 140 may be no greater than about 1 mm. In this way, the risk of the diffuser plate 140 and the optical film 150 falling can be reduced. In some embodiments, the support pin 160 may be arranged between adjacent light-emitting elements 130. For example, the cross-sectional area of ​​the support pin 160 gradually decreases toward the diffuser plate 140, but the present invention is not limited to this.

[0065] In some embodiments, the display panel 200 is disposed above the backlight module 100. In some embodiments, the display panel 200 includes a polarizing film 211, a polarizing film 212, an upper substrate 221, and a lower substrate 222. The polarizing films 211 and 212 may be located above and below the upper substrate 221 and the lower substrate 222, that is, the upper substrate 221 and the lower substrate 222 are located between the polarizing films 211 and 212. For example, the upper substrate 221 and / or the lower substrate 222 may be a flexible substrate or an inflexible substrate. The materials of the upper substrate 221 and the lower substrate 222 may include, for example, glass, sapphire, ceramic, plastic, or other suitable materials, wherein the plastic material may be, for example, polyimide (PI), polyethylene terephthalate (PET), polycarbonate (PC), polyether sulfone (PES), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN) or polyarylate (PAR), other suitable materials, or a combination thereof, but not limited thereto. In some embodiments, the upper substrate 221 and the lower substrate 222 may be provided with a liquid crystal layer (not shown), which may include nematic liquid crystal, smectic liquid crystal, cholesteric liquid crystal, blue phase liquid crystal, or any other suitable liquid crystal material. It should be understood that although two layers of polarizing films 211 and 212 are shown in this embodiment, located on the upper and lower sides of the upper substrate 221 and the lower substrate 222, respectively, a person skilled in the art should be able to adjust the number and position of the polarizing films 211 and 212 as needed. In addition, the display device 10 may include a cover plate 300, which is bonded to the back plate 110 via an adhesive 180. This protects the internal components of the display device 10. An adhesive 230 may be provided between the cover plate 300 and the display panel 200 to bond the cover plate 300 and the display panel 200. In some embodiments, the adhesive 230 may be an optical clear adhesive (OCA). For example, the structure of this embodiment can be applied to the left and right sides of the display device 10 , but the present invention is not limited thereto.

[0066] Figure 4 A partial stereoscopic schematic diagram of a display device 10 according to some embodiments of the present invention is shown. Figure 4As shown, the light emitting elements 130 can be arranged on the circuit substrate 120 in a matrix manner. The backlight module 100 can have a light emitting area. In some embodiments, the light emitting area can be an area where the light emitting elements 130 are arranged, but the present invention is not limited thereto. In some embodiments, the light emitting area can be an area where the light emitted by the light emitting elements 130 can reach. In some embodiments, the edge of the light emitting area can be, for example, an edge of the circuit substrate 120. In some embodiments, the edge of the light emitting area can be, for example, an edge of the bottom surface 111. Figure 4 As shown, in some embodiments, a row of light-emitting elements 130 is disposed between the support pin 160 and the edge of the light-emitting area. The term "row" may refer to a plurality of light-emitting elements 130 arranged along the Y-axis. In some embodiments, one to five rows of light-emitting elements 130 are disposed between the support pin 160 and the edge of the light-emitting area. In some embodiments, two to five rows of light-emitting elements 130 are disposed between the support pin 160 and the edge of the light-emitting area. In some embodiments, the ratio of the distance between the support pin 160 and the edge of the light-emitting area to the length of the light-emitting area along the extension direction of the light-emitting area is greater than or equal to 1 / 30 and less than or equal to 1 / 10. In some embodiments, the minimum distance between one of the support pins 160 and the edge of the light-emitting area is less than or equal to 40 mm and greater than or equal to 10 mm. This allows the support pin 160 to effectively support the edge of the diffuser plate 140, reducing the risk of the diffuser plate 140 and the optical film 150 falling. For example, the minimum distance is measured between the center of the support pin 160 and the edge of the light-emitting area, but the present invention is not limited thereto. In some embodiments, the back plate 110 includes a first region R1 provided with a support pin 160 and a second region R2 located at the center of the back plate 110, wherein the second region R2 is not provided with a support pin 160. In some embodiments, the density of the light-emitting elements 130 in the first region R1 may be equal to the density of the light-emitting elements 130 in the second region R2. However, the present invention is not limited to this. In some embodiments, the density of the light-emitting elements 130 in the first region R1 may be different from (for example, less than) the density of the light-emitting elements 130 in the second region R2. Regarding the measurement of the density of the light-emitting elements 130, in some embodiments, it can be, for example, the number of light-emitting elements 130 contained in the same area. The greater the number, the greater the density. In some embodiments, the number of the same light-emitting elements 130 can be taken, and the area surrounded by these light-emitting elements 130 in the top view direction can be measured. The smaller the surrounded area, the greater the density.

[0067] In some embodiments, the circuit substrate 120 may be provided with a plurality of holes 121 located between adjacent light emitting elements 130. For example, the holes 121 may be used to accommodate the support pins 160, which will be described below with reference to FIG. Figure 6Further explanation. In some embodiments, the hole 121 can be helpful in positioning the light-emitting element 130. In addition, the backlight module 100 may include a support member 170, which is disposed on the side wall of the back panel 110. In some embodiments, the support member 170 can be used to support the edges of the diffuser plate 140 and the optical film 150. In addition, in some embodiments, the support member 170 can be made of a light-shielding material. In this way, the support member 170 can block the light emitted from the diffuser plate 140, thereby reducing the risk of mura problems in the display device 10. For example, the structure of this embodiment can be applied to the left and right sides of the display device 10, but the present invention is not limited to this.

[0068] Figure 5 A schematic top view of a display panel 200 according to some embodiments of the present invention is shown. Figure 5 As shown, the distance D1 between one of the support pins 160 and the edge of the active area 201 of the display panel 200 is less than 40 mm. For example, distance D1 is the minimum distance measured between the center of the support pin 160 and the edge of the active area 201, but the present invention is not limited to this. In some embodiments, the distance D2 between the support pins 160 on both sides of the display panel 200 is much greater than the distance D1 between one of the support pins 160 and the edge of the active area 201 of the display panel 200. In this way, the support pins 160 can effectively support the edge of the diffuser plate 140.

[0069] Figure 6 A partial cross-sectional schematic diagram of a display device 10 according to some embodiments of the present invention is shown. Figure 6 As shown, the support pin 160 can be accommodated in the groove 115 of the back plate 110. In some embodiments, the groove 115 can be recessed from the bottom surface 111 of the back plate 110. The support pin 160 can be disposed in the groove 115 and pass through the hole 121 of the circuit substrate 120. Specifically, the support pin 160 can be first disposed in the groove 115, and then the circuit substrate 120 can be disposed on the back plate 110 and the support pin 160. In this way, the risk of the support pin 160 interfering with the light-emitting element 130 or the risk of the support pin 160 shifting and becoming inoperative can be reduced.

[0070] Figure 7 A partial cross-sectional view of a display device 10 according to some embodiments of the present invention is shown. For example, Figure 7 Can be along Figure 1 The diagram is shown by the line BB, but the present invention is not limited thereto. Figure 7As shown, the support member 170 can be bonded to the sidewall of the back panel 110 via an adhesive 185 and can be used to support the edges of the diffuser plate 140 and the optical film 150. In some embodiments, the support member 170 can overlap with the edges of the diffuser plate 140 and the optical film 150 in the normal direction of the display device 10 (e.g., parallel to the Z-axis), thereby shielding light emitted from the diffuser plate 140 and reducing the risk of mura issues in the display device 10. In some embodiments, the support pins 160 and / or the support member 170 can contact the diffuser plate 140, but the present invention is not limited to this. In some embodiments, the distance between the support pins 160 (or support member 170) and the diffuser plate 140 in the normal direction (e.g., vertical direction) of the diffuser plate 140 is greater than or equal to 0 mm and less than or equal to 0.3 mm. This reduces the risk of the diffuser plate 140 and the optical film 150 falling. For example, the structure of this embodiment can be applied to the left and right sides of the display device 10, but the present invention is not limited to this. In some embodiments, in a cross-sectional view, in the extension direction of the diffuser plate 140 (for example, the horizontal direction), the width of the overlap between the support member 170 and the diffuser plate 140 is less than or equal to 0.2 mm and greater than or equal to 0.01 mm. In some embodiments, the corner of the support member 170 close to the diffuser plate 140 may be an arc-angle structure or a chamfered structure. Specifically, the diffuser plate 140 may shrink at a temperature below room temperature, causing the diffuser plate 140 to separate from the support member 170. Conversely, when the temperature returns to above room temperature, the diffuser plate 140 may expand, causing the diffuser plate 140 to be supported by the support member 170 again. The configuration of the arc-angle structure 174 can facilitate the diffuser plate 140 to return to the top of the support member 170 and have sufficient support.

[0071] Figure 8 A partial perspective schematic diagram of a display device 10 according to some embodiments of the present invention is shown. For example, Figure 8 Can be along Figure 1 In this embodiment, the support pin 160 may be omitted, but the present invention is not limited thereto. Figure 8As shown, the support member 170 may have an extension portion 172 extending toward the edges of the diffuser plate 140 and the optical film 150. In some embodiments, the extension portion 172 may extend from the top surface 171 of the support member 170, but the present invention is not limited thereto. In some embodiments, the extension portion 172 may be formed with an arc-angle structure 174 corresponding to the bottom surface of the diffuser plate 140. Specifically, the diffuser plate 140 may shrink at a temperature below room temperature, causing the diffuser plate 140 to separate from the support member 170. Conversely, when the temperature returns to above room temperature, the diffuser plate 140 may expand, causing the diffuser plate 140 to be supported by the support member 170 again. The configuration of the arc-angle structure 174 can facilitate the diffuser plate 140 to return to the top of the support member 170 and have sufficient support.

[0072] In some embodiments, the support member 170 may have a chamfered structure 175 facing the circuit substrate 120. In some embodiments, the support member 170 may be separated from the circuit substrate 120 (i.e., a gap is formed between the support member 170 and the circuit substrate 120), thereby reducing the risk of interference between the support member 170 and the circuit substrate 120, but the present invention is not limited to this. For example, the gap formed between the support member 170 and the circuit substrate 120 may be between 0 (i.e., the support member 170 may be in contact with the circuit substrate 120) and about 0.3 mm.
