Detailed Description

The electronic device according to the embodiment of the present invention is described below. It should be appreciated, however, that the present embodiments provide many suitable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments disclosed are merely illustrative of specific ways to make and use the invention, and do not delimit the scope of the invention.

The present invention may be understood by reference to the following detailed description taken in conjunction with the accompanying drawings, in which it is noted that, for the sake of clarity, the various drawings depict only some of the electronic devices and that certain elements of the drawings are not necessarily drawn to scale. In addition, the number and size of the elements in the drawings are merely illustrative and are not intended to limit the scope of the present invention.

Certain terms are used throughout the description and following claims to refer to particular elements. Those skilled in the art will appreciate that electronic device manufacturers may refer to the same components by different names. This document does not intend to distinguish between components that differ in function but not name. In the following specification and claims, the terms "including", "comprising", "including", "having", and the like are open-ended terms, and thus should be interpreted to mean "including, but not limited to, \8230;". Thus, when the terms "comprises", "comprising", "includes" and/or "including" are used in the description of the invention, they specify the presence of stated features, regions, steps, operations, and/or components, but do not preclude the presence or addition of one or more other features, regions, steps, operations, and/or components.

Furthermore, relative terms, such as "below" or "bottom" and "above" or "top," may be used in connection with the embodiments to describe one element's relative relationship to another element in the figures. It will be understood that if the device of the drawings is turned over and turned upside down, elements described as being on the "lower" side will be elements on the "upper" side.

When a corresponding element (e.g., layer or region) is referred to as being "on" another element, it can be directly on the other element or intervening elements may also be present. On the other hand, when an element is referred to as being "directly on" another element, there is no element present therebetween. In addition, when a component is referred to as being "on" another component, the two components may be located above or below the other component in a top-down relationship, depending on the orientation of the device.

The terms "about," equal, "or" identical, "substantially," or "approximately" are generally to be construed as being within 20% of a given value or range, or as being within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range.

It will be understood that, although the terms first, second, etc. may be used herein to describe various elements, layers and/or sections, these elements, layers and/or sections should not be limited by these terms, but rather should be used to distinguish one element, layer and/or section from another element, layer and/or section. Thus, a first element, layer and/or section discussed below could be termed a second element, layer and/or section without departing from the teachings of some embodiments of the present invention. In addition, for the sake of brevity, terms such as "first" and "second" may not be used in the description to distinguish different elements. The first element and/or the second element recited in the claims may be construed as any element conforming to the description in the specification without departing from the scope defined by the appended claims.

Unless defined otherwise, 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 disclosure belongs. It will be 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 invention and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein. In addition, the term "substrate" may include any device formed on a substrate or various layers overlying a substrate, such as any desired active devices (e.g., transistors) formed thereon, although only a planar substrate is illustrated for simplicity.

Fig. 1 is a schematic top view illustrating an electronic device 100 according to an embodiment of the invention. It should be noted that the electronic device 100 may include a display device, an antenna device (e.g., a liquid crystal antenna), a sensing device, or a splicing device, but not limited thereto. The electronic device may include a bendable or flexible electronic device. The electronic device may include liquid crystal, light emitting diode, organic Light Emitting Diode (OLED), wherein the light emitting diode may include sub-millimeter light emitting diode (mini LED), micro light emitting diode (micro LED), or quantum dot light emitting diode (QD, including, for example, QLED, QDLED), fluorescent (fluorescent), phosphorescent (phosphor), other suitable materials, or combinations thereof, but is not limited thereto. The antenna device may be, for example, a liquid crystal antenna, but is not limited thereto. The splicing device may be, for example, a display splicing device or an antenna splicing device, but is not limited thereto. It should be noted that the electronic devices can be any permutation and combination of the foregoing, but not limited thereto. The present invention will be described below with reference to a display device as an electronic device or a tiled device, but the present invention is not limited thereto.

Referring to fig. 1, the electronic device 100 includes a panel 150. For example, the panel 150 may be a display panel. As shown in fig. 1, the panel 150 is rectangular, but is not limited thereto. In this embodiment, the panel 150 has a first corner 150A, a second corner 150B, and a bottom surface 150C, wherein the bottom surface 150C connects the first corner 150A and the second corner 150B. The electronic device 100 may further include a first support 160 and a second support 170, which respectively correspond to the first corner 150A and the second corner 150B of the panel 150. In some embodiments, the electronic device 100 may be in a vertical configuration. When the user looks at the panel 150, the first corner 150A, the second corner 150B and the bottom surface 150C are located below (i.e., lower, such as the bottom surface 150C facing the ground). At this time, the first support 160 supports the first corner 150A of the panel 150, and the second support 170 supports the second corner 150B of the panel 150. In some embodiments, the electronic device 100 may be provided with at least two supports, respectively corresponding to the corners of the panel 150, but is not limited thereto. Young's modulus of the first support 160 and Young's modulus of the second support 170 are in the range of 500 megapascals (MPa) to 2500 megapascals (MPa) (500 MPa ≦ 2500 MPa), such as 750MPa, 900MPa, 1000MPa, 1100MPa, 1250MPa, 1500MPa, 1750MPa, 2000MPa, 2250MPa, and the like, but are not limited to the above-listed values. For example, the material of the first and

second supports

160 and 170 may include Thermoplastic Vulcanizate (TPV), thermoplastic Elastomer (TPE), and the like, but is not limited thereto.

Referring to fig. 2, fig. 2 isbase:Sub>A schematic cross-sectional view taken along linebase:Sub>A-base:Sub>A of fig. 1. In this embodiment, the electronic device 100 may include a backlight module, but is not limited thereto. As shown in fig. 2, the electronic device 100 may include a back plate 110. In some embodiments, the material of the back plate 110 may include metal, plastic, other suitable materials, or a combination thereof, but is not limited thereto. The back plate 110 may have a certain structural strength, so as to support the electronic device 100. The back plate 110 may be disposed with a reflective sheet 120 and a light emitting device 121, wherein the light emitting device 121 may be disposed on the reflective sheet 120, so that light emitted by the light emitting device 121 may be reflected to the panel 150 of the electronic device 100 by the reflective sheet 120, thereby improving the utilization rate of the light.

In the present embodiment, the first support 160 may include a body portion 161, a first partition portion 162, and a support portion 163. Body portion 161 may extend in a direction substantially parallel to panel 150 (e.g., the X-Z plane). The first spacing portion 162 and the supporting portion 163 may protrude from the main body 161 and are respectively located at two opposite sides of the main body 161. Similarly, the second support 170 may include a body portion 171, a second spacer portion 172, and a support portion 173. The body portion 171 may extend in a direction substantially parallel to the panel 150. The second spacing portion 172 and the supporting portion 173 protrude from the body portion 171 and are respectively located at two opposite sides of the body portion 171. In the present embodiment, the reflective sheet 120 may extend to the lower portions of the first and

second supports

160 and 170, and the supporting

portions

163 and 173 contact the reflective sheet 120.

A diffusion plate 130 is provided on the reflection sheet 120 and the light emitting elements 121 to diffuse light from the light emitting elements 121. In the present embodiment, the diffuser 130 may be disposed between the supporting

portions

163 and 173 in the cross-sectional view. In some embodiments, the diffusion plate 130 may contact the body 161 and the lower surface (i.e., the surface facing the light emitting element 121) of the body 171, but is not limited thereto. An optical film 140 may be disposed on the diffusion plate 130 to perform an appropriate optical process on the light passing through the diffusion plate 130. In the present embodiment, the optical film 140 may be positioned between the body portion 161 and the body portion 171 in a cross-sectional view. The thickness of the optical film 140 may be less than the thickness of the body part 161 and/or less than the thickness of the body part 171, but is not limited thereto. In some embodiments, the thickness of the optical film 140 may be substantially equal to the thickness of the body portion 161 and/or greater than the thickness of the body portion 171. The thicknesses of the optical film 140, the body portion 161, and the body portion 171 are measured, for example, in the Y direction.

A panel 150 may be disposed on the optical film 140. In an embodiment, the panel 150 may be a liquid crystal display panel, but is not limited thereto. For example, the panel 150 may include a first substrate 151, a second substrate 153, and a liquid crystal layer (not shown). The second substrate 153 may be disposed on the first substrate 151. The liquid crystal layer may be disposed between the first substrate 151 and the second substrate 153. The panel 150 may include a driving circuit layer (not shown), a filter layer (not shown), a light-shielding layer (not shown), and/or other suitable devices disposed between the first substrate 151 and the second substrate 153. In the present embodiment, a conductive pad 152 is disposed on one side (for example, but not limited to, the right side of fig. 2) of the first substrate 151, wherein the conductive pad 152 can be used to electrically connect the panel 150 with an external circuit (for example, a control circuit). In some embodiments, the conductive pad 152 may be disposed on the bottom surface 150C of the panel 150 (as shown in fig. 1), but is not limited thereto.

In the present embodiment, the first support 160 is disposed at a side close to the conductive pad 152, and the second support 170 is disposed at a side far away from the conductive pad 152. In some embodiments, the panel 150 may be disposed on the

body portions

161 and 171 of the first and

second supports

160 and 170, and contact the first and

second spacing portions

162 and 172 of the first and

second supports

160 and 170. Since the first and second supporting

members

160 and 170 have a young's modulus in a proper range, damage to the panel 150 may be reduced, or a buffering effect of the panel 150 may be provided.

In addition, the lower polarizer 141 may be disposed under the panel 150, and the upper polarizer 142 may be disposed on the panel 150, but the invention is not limited thereto, and at least one of them may be omitted. In the present embodiment, the lower polarizer 141 and the upper polarizer 142 are overlapped with the main body 161 and the main body 171 when viewed from a top direction (e.g., Y axis). In some embodiments, the configuration or the number of the lower polarizer 141 and the upper polarizer 142 may be adjusted by one of ordinary skill in the art according to requirements. In other words, the lower polarizer 141 or the upper polarizer 142 may be selectively disposed, or the multi-layer lower polarizer 141 or the multi-layer upper polarizer 142 may be disposed. In some embodiments, the thickness T1 of the first spacer 162 (and the second spacer 172) may be substantially equal to the total thickness of the panel 150, the lower polarizer 141 and the upper polarizer 142. More specifically, the ratio of the thickness of the first spacer 162 (and the second spacer 172) to the total thickness of the panel 150, the lower polarizer 141 and the upper polarizer 142 may be between 90% and 110% (90% ≦ 110% thickness ratio), such as 95%, 100% (i.e., both equal), 105%, etc., but is not limited to the above-listed values. With the above configuration, the electronic device 100 can reduce the probability of generating defects such as light leakage.

In addition, the outer frame 180 may be optionally disposed to protect the components inside the electronic device 100. In the present embodiment, the outer frame 180 is disposed on the first support 160, the second support 170 and the back plate 110, and the outer frame 180 can extend to the outer side of the back plate 110. For example, the material of the outer frame 180 may include, but is not limited to, metal, plastic, other suitable materials, or a combination thereof.

FIG. 3 shows a schematic diagram of an electronic device 100 according to some embodiments of the present invention. As shown in fig. 3, the first support 160 further includes a first side 164 supporting the first corner 150A of the panel 150, wherein the first side 164 has a first length L1. Similarly, the second support 170 further includes a second side 174 supporting the second corner 150B of the panel 150, wherein the second side 174 has a second length L2. In an embodiment, the first length L1 may be a maximum length of the first side portion 164, and the second length L2 may be a maximum length of the second side portion 174, but is not limited thereto. In addition, the panel 150 has a length P. The lengths of the aforementioned panel 150, first side 164 and second side 174 are measured, for example, in the X direction. Since the first and

second side portions

164 and 174 are spaced apart from each other, the upper limit of the first and second lengths L1 and L2 is one-half of the length P (L1 < P/2 and L2 is less than P/2). Too long of the first length L1 (or the second length L2) may cause the portion of the first side portion 164 (or the second side portion 174) near the middle of the bottom surface 150C to sag and affect the display taste (mura) of the panel 150. In some embodiments, the first length L1 and the second length L2 may be less than one quarter of the length P, respectively, but are not limited thereto.

Fig. 4 shows a schematic diagram of the electronic device 100 according to some embodiments of the invention, and fig. 5 shows a partially enlarged schematic diagram of the electronic device 100 according to some embodiments of the invention. As shown in fig. 4 and 5, since the panel 150 has a weight W, it presses the first side portion 164 and the second side portion 174, such that the first side portion 164 and the second side portion 174 generate a deformation length Δ h (calculated by the thickness of the first side portion 164 and the second side portion 174 in the Z direction). For example, the first length L1 and the deformation length Δ h of the first side 164 can be plottedA dummy triangle is shown, and the first length L1 and the deformation length Δ h have a deformation angle θ (shown in fig. 5). Generally, if the deformation angle θ is greater than 1 ^° In this case, the user can perceive that the panel 150 is deformed, which affects the visual perception. Therefore, in order to prevent the user from perceiving that the panel 150 is deformed, the deformation angle θ must be less than or equal to 1 ^° 。

According to generalized Hooke's law, the stress generated by the weight of the panel 150 may be substantially equal to the Young's modulus of the first side portion 164 (or the second side portion 174) multiplied by the deformation length Δ h. Thus, the critical values of the first length L1 and the second length L2 can be obtained. However, since the above calculation is based on an ideal assumption to derive a numerical value, it may not be in accordance with the real situation. The critical value is multiplied by a safety factor (10 in this embodiment, but not limited thereto, and the safety factor in other embodiments may be any value greater than 1, such as 5, 8, or 15, depending on the operating environment of the electronic device) in consideration of the actual conditions (such as elastic fatigue, oxidation, loss, stress distribution, etc.). In summary, it can be seen that the first length L1 and the second length L2 satisfy the following equations:

w is the weight of panel 150 (newtons, N), P is the length of panel 150 (mm), L1 is the first length (mm), k1 is the young's modulus of first side 164 (i.e., first support 160) (megapascals, MPa), L2 is the second length (mm), k2 is the young's modulus of second side 174 (i.e., second support 170) (megapascals, MPa), and each of k1 and k2 is in the range of 500 to 2500. In this example, a 1 kilogram weight (kgw) is approximately equal to 9.8 newtons (N).

Fig. 6 shows a top view of the first support 160 and the second support 170 according to some embodiments of the invention. As shown in fig. 6, the main body portion 161 of the first support 160 may include a first section 161A and a second section 161B, the first section 161A and the second section 161B may extend in substantially perpendicular directions (e.g., X-direction and Z-direction), and similarly, the main body portion 171 of the second support 170 may include a first section 171A and a second section 171B, the first section 171A and the second section 171B may extend in substantially perpendicular directions (e.g., X-direction and Z-direction). The width W1 of the first region 161A of the main body portion 161 is greater than the width W2 of the second region 161B, wherein the width W1 of the first region 161A is measured along the Z-direction, and the width W2 of the second region 161B is measured along the X-direction. In an embodiment, the width W1 is the maximum width of the first region 161A, and the width W2 is the maximum width of the second region 161B, but is not limited thereto.

In addition, in the present embodiment, the first length L1 of the first side portion 164 is greater than the third length L3 of the first spacing portion 162, wherein the length of the first side portion 164 is measured along the X direction, and the length of the first spacing portion 162 is measured along the Z direction. In an embodiment, the third length L3 of the first spacing portion 162 is the maximum length of the first spacing portion 162, but is not limited thereto. In the present embodiment, the maximum width of the first side portion 164 is greater than the maximum width of the first spacer 162, wherein the maximum width of the first side portion 164 is measured along the Z-direction, and the maximum width of the first spacer 162 is measured along the X-direction. Through the above design, the first side portion 164 can provide a better supporting effect for the panel 150. Similarly, the second side portion 174 may have a second length L2, the second spacer portion may have a fourth length L4, the first region 171A of the body portion 171 may have a width W3, and the second region 171B of the body portion 171 may have a width W4. In an embodiment, the second length L2 and the fourth length L4 may be maximum lengths, and the width W3 and the width W4 may be maximum widths, but are not limited thereto.

The first side 164 may further include a bevel 165, wherein the bevel 165 is non-parallel to the direction of extension (e.g., the X-Z plane) of the panel 150. In some embodiments, bevel 165 faces frame 180 (shown in fig. 2). Therefore, a gap is generated between the outer frame 180 and the first side portion 164, and the probability of interference between the outer frame 180 and the first side portion 164 can be reduced. In addition, the first side portion 164 may have a groove 166 and/or a slot 167 adjacent to each other, wherein the groove 166 and the slot 167 correspond to the abutting surfaces 169 (shown in fig. 8) of the faceplate 150 and the first side portion 164. More specifically, the abutment surface 169 overlaps the recess 166 and the notch 167 when viewed in the Z direction. In this embodiment, the width of the groove 166 may be larger than the width of the card slot 167, wherein the widths of the groove 166 and the card slot 167 are measured along the X direction, for example. In one embodiment, the width of the groove 166 and the slot 167 are both the maximum width. Further, the depth of recess 166 may be less than the depth of card slot 167, wherein the depth of the aforementioned recess 166, card slot 167 is measured, for example, in the Z-direction. In one embodiment, the depth of the

grooves

166, 167 may be a maximum depth. In some embodiments, the ramp 165 may intersect the groove 166, the catch 167. In other words, the inclined surface 165 overlaps the groove 166 and the card slot 167 when viewed in a direction (for example, Y direction) perpendicular to the extending direction of the faceplate 150. In addition, in some embodiments, the first spacer 162 is also provided with a groove 168, the second side 174 is provided with a groove 175, and the second spacer 172 is provided with a snap groove 176 for assembling the positioning structure of the electronic device 100. It should be understood that the positions of the grooves and the slots are merely illustrative and do not represent actual arrangements in accordance with the embodiments of the present invention. The above structure can be adjusted by one of ordinary skill in the art according to the needs, and will not be described in detail below.

Fig. 7 shows a schematic cross-sectional view of the first support 160 and the panel 150 according to an embodiment of the present invention. As shown in fig. 7, the maximum thickness of the first side portion 164 may be greater than the maximum thickness of the panel 150, but is not limited thereto. In some embodiments, the thickness of the first side 164 may be substantially equal to the thickness of the panel 150. For example, the thickness of the first side portion 164 is in the range of 2.0mm to 2.5mm (2.0 mm ≦ thickness ≦ 2.5 mm), such as 2.1mm, 2.2mm, 2.3mm, 2.4mm, and the like, but is not limited to the above-listed values. In some embodiments, the difference between the thickness of the first side 164 and the thickness of the panel 150 is in the range of 0.5mm to 0.8mm (0.5 mm ≦ thickness difference ≦ 0.8 mm), such as 0.6mm, 0.7mm, and the like, but is not limited to the values listed above. By the above design, the probability of collision between the panel 150 and rigid elements (e.g., the back plate 110, the outer frame 180, etc.) can be reduced, so as to protect the panel 150. In the present embodiment, the panel 150 contacts the first side portion 164 and the first spacing portion 162, but is not limited thereto.

FIG. 8 shows an enlarged partial top view of the electronic device 100 according to some embodiments of the invention. As shown in fig. 8, the back plate 110 has a sidewall 111, wherein the sidewall 111 includes a support portion 112 and a fastening portion 113, and the support portion 112 and the fastening portion 113 extend along different directions. For example, but not limited to, the extending direction (for example, X direction) of the support portion 112 and the extending direction (for example, Z direction) of the engaging portion 113 are substantially perpendicular. In this embodiment, the groove 166 is disposed to face the bearing portion 112, and the catching groove 167 is disposed to receive the catching portion 113. A portion of the bearing portion 112 is arcuate (having a curvature greater than 0, i.e., non-planar) and may be convex toward the groove 166. In some embodiments, the rest portion 112 does not abut an edge of the groove 166 to provide room for the first side portion 164 to cushion, but is not limited to such. Through the above design, it is possible to facilitate the assembly of the first support 160 and the back plate 110, or to improve the strength of the support panel 150.

In summary, the embodiments of the present invention provide an electronic device having a plurality of supporting members for supporting a panel. By setting the first side portion of the first supporting member (and/or the second side portion of the second supporting member) supporting the panel to have a specific length, the probability that the panel is deformed by naked eyes of a user can be reduced, and the display performance of the electronic device can be maintained. In addition, the recessed structures for assembling and positioning are arranged on the first supporting piece and/or the second supporting piece, so that the assembly of the first supporting piece, the second supporting piece and the back plate can be facilitated, or the strength of the supporting panel can be improved.
