Thedisplay medium 102 is disposed between thearray substrate 100 and thelight filter 104. Thedisplay panel 10 has adisplay surface 106. In some embodiments, thedisplay surface 106 of thedisplay panel 104 may be a surface of thelight layer 104 located away from thesubstrate 100, but the present disclosure is not limited thereto. In some embodiments, thedisplay surface 106 also may be a surface of thedisplay panel 10 facing an user or a surface of the display panel located away from thebacklight module 15. In some embodiments, thedisplay medium 102 may be a liquid crystal display medium. In some embodiments, the backlight module 15 (including thelight guiding plate 150, theoptical film 152, and the reflective layer 154) may provide the light source required for thedisplay panel 10 because the liquid crystal display medium cannot emit light by itself. - In
FIG. 2A andFIG. 2B , thefirst substrate 130 covers thelight filter 104 of thedisplay panel 10. Thesecond substrate 132 is located below thearray substrate 104 of thedisplay panel 10. In some embodiments, thefirst substrate 130 may include an upper polarizer (not shown), and thesecond substrate 132 may include a lower polarizer (not shown). In addition, if thedisplay panel 10 is a self-illuminating display panel (for example, an organic electroluminescent display panel, a reflective display panel, an electrophoretic display panel, etc.), thedisplay panel 10 may omit the backlight module. - In
FIGS. 1B, 2A, and 2B , theframe 12 includes asidewall 120 and a supportingportion 122. Thesidewall 120 of theframe 12 surrounds and forms anaccommodating space 124 and anopening 126 that allows theaccommodating space 124 to communicate with the outside of theframe 12. Thebacklight module 15 is located in theaccommodating space 124. The supportingportion 122 of theframe 12 protrudes from thesidewall 120 toward theaccommodating space 124. Thedisplay panel 10 is supported by the supportingportion 122 of theframe 12. - In some embodiments, a
top surface 120 t of thesidewall 120 of theframe 12 is lower than thedisplay surface 106, but the present disclosure is not limited thereto. In some embodiments, a height of thetop surface 120 t of thesidewall 120 of theframe 12 relative to abottom plate 162 of thehousing 16 is substantially the same as a height of thedisplay surface 106 relative to thebottom plate 162 of thehousing 16. In some embodiments, thedisplay panel 10 is attached to theframe 12 through the connectingstructure 17. The connectingstructure 17 may be, for example, a double-sided tape or other suitable material, but the present disclosure is not limited thereto. - In
FIGS. 2A and 2B , thehousing 16 includes thebottom plate 162 and asidewall 160 surrounding thebottom plate 162. Theframe 12 is disposed in thehousing 16. Abottom portion 120 b of theframe 12 located away from the protrudingstructure 14 is supported by thebottom plate 162 of thehousing 16. In some embodiments, atop surface 160 t of thesidewall 160 of thehousing 16 is higher than thetop surface 120 t of thesidewall 120 of theframe 12, but the present disclosure is not limited thereto. In some embodiments, a height of thetop surface 160 t of thesidewall 160 of thehousing 16 relative to thebottom plate 162 is substantially the same as a height of thetop surface 120 t of thesidewall 120 of theframe 12 relative to thebottom plate 162 of thehousing 16. - In
FIG. 2B , the protrudingstructure 14 and thedisplay surface 106 are located at the same side of theframe 12 and thedisplay panel 10. In some embodiments, the protrudingstructure 14 may be a strip protrusion, and extends in a direction substantially perpendicular to aninner edge 126 n of theopening 126 of theframe 12 and from theopening 126 to an outer edge 120 o of thetop surface 120 t of thesidewall 120. In some embodiments, thestrip protrusion 14 has a height H1 relative to thetop surface 120 t of theframe 12, and the height H1 is substantially equal to or lower than a height H2 of thedisplay panel 10 relative to thetop surface 120 t of theframe 12. Therefore, when theadhesive structure 18 as shown inFIG. 2A adheres to theframe 12 and thedisplay panel 10 by the protrudingstructure 14, theadhesive structure 18 may further press thedisplay panel 10 against theframe 12, thereby improving the stability of the overall structure of thedisplay device 1. Furthermore, in the process of bonding thedisplay panel 10 to theframe 12, the relationship between the protrudingstructure 14 and theframe 12 also contributes to the bonding, thereby improving the convenience of thedisplay device 1 at the time of assembly. - In some embodiments, the height H1 of the protruding
structure 14 relative to thetop surface 120 t of theframe 12 is higher than a height of thesidewall 160 of thehousing 16 relative to thetop surface 120 t of theframe 12, but the present disclosure is not limited thereto. For example, a height of the protrudingstructure 14 relative to thetop surface 120 t of theframe 12 may be substantially equal to thesidewall 160 of thehousing 16 relative to thetop surface 120 t of theframe 12. Therefore, when theadhesive structure 18 as shown inFIG. 2A adheres to theframe 12 and thehousing 16 by the protrudingstructure 14, theadhesive structure 18 may further press theframe 12 against thehousing 16, thereby improving the stability of the overall structure of thedisplay device 1. - In some embodiments, the protruding
structure 14 has a width W1 in a direction along theinner edge 126 n ofopening 126. In some embodiments, a distance between two adjacent protrudingstructures 14 is greater than about the width W1, but the present disclosure is not limited thereto. For example, the distance between the two adjacent protrudingstructures 14 may be about twice of the width W1. In some embodiments, an area of a vertical projection of the protrudingstructures 14 on thetop surface 120 t of theframe 12 is smaller than about one half of an area of thetop surface 120 t, but the present disclosure is not limited thereto. For example, the area of the vertical projection of the protrudingstructures 14 on thetop surface 120 t of theframe 12 may be about one third of the area of thetop surface 120 t. - Since the thermal expansion coefficient of the
frame 12 is greater than the thermal expansion coefficient of thedisplay panel 10 as shown inFIG. 2A , when theadhesive structure 18 is adhered to the protrudingstructure 14 and thedisplay device 1 is at a non-room temperature, theframe 12 and thedisplay panel 10 will push against each other through theadhesive structure 18, thus breaking a connection between thedisplay panel 10, theframe 12 and/or theadhesive structure 18. In some embodiments, a contact area between theadhesive structure 18 and theframe 12 may be reduced by the protrudingstructure 14 on theframe 12, so as to reduce the difference between a contact area between theadhesive structure 18 and thedisplay panel 10 and that between theadhesive structure 18 and theframe 12, such that the chances of theadhesive structures 18 being separated (peeled off) from thedisplay panel 10, the protrudingstructure 14, and thehousing 16 may be reduced, thereby improving the strength of the overall structure of thedisplay device 1 at the non-room temperature. - In some embodiments, the protruding
structure 14 has aside surface 142. Theside surface 142 of the protrudingstructure 14 is not in contact with the adhesive structure 18 (seeFIG. 2A ). In addition, a portion of theframe 12 between the two adjacent protrudingstructures 14 is not in contact with the adhesive structure 18 (seeFIG. 2A ). In some embodiments, theadhesive structure 18 may be a layered structure. - In
FIG. 2B , theadhesive structure 18 as shown inFIG. 2A is sequentially adhered to thedisplay surface 106 of thedisplay panel 10, atop surface 140 t of the protrudingstructure 14 located away from theframe 12, aside surface 160 s of thesidewall 160, and thebottom plate 162 of thehousing 16. A thickness T (seeFIG. 2A ) of theadhesive structure 18 is smaller than the height H1 of the protrudingstructure 14 relative to theframe 12, thereby preventing theadhesive structure 18 from contacting thetop surface 120 t of thesidewall 120. - In some embodiments, the
adhesive structure 18 simultaneously covers thedisplay panel 10 and the protrudingstructure 14 on theframe 12, such that thedisplay panel 10 is connected to theframe 12 by theadhesive structure 18. In some embodiments, thedisplay device 1 having theadhesive structure 18 and the protrudingstructure 14 may prevent wrinkles, shrinkage or peeling from occurring on theadhesive structure 18 after a reliability test (RAT). For example, the reliability test includes a temperature/humidity storage test (TST), a high temperature storage test (HTS) or any other suitable tests. - In
FIG. 3B , the display device further includes protrudingstructures 19. The protrudingstructures 19 and thedisplay surface 106 are located at the same side of theframe 12 and thedisplay panel 10. In some embodiments, the protrudingstructures 19 may be strip protrusions respectively and are arranged substantially along anouter edge 120 p of thetop surface 120 t of thesidewall 120. - Specifically, each of the protruding
structure 19 has a width W2 in a direction along theouter edge 120 p. In some embodiments, a distance between two adjacent protrudingstructures 19 is greater than the width W2, but the present disclosure is not limited thereto. For example, the distance between the two adjacent protrudingstructures 19 may be about twice of the width W2. Further, the protrudingstructure 19 has a width W3 in a direction substantially perpendicular to theouter edge 120 p. In some embodiments, a distance between the protrudingstructure 19 and theinner edge 126 n of theopening 126 is greater than about the width W3, but the present disclosure is not limited thereto. For example, the distance between the protrudingstructure 19 and theinner edge 126 n of theopening 126 may be about twice of the width W3. - Since the thermal expansion coefficient of the
frame 12 is greater than the thermal expansion coefficient of thedisplay panel 10 as shown inFIG. 2A , a contact area between theadhesive structure 18 and theframe 12 may be reduced by the protrudingstructure 14 on theframe 12, thus reducing the difference between a contact area between theadhesive structure 18 and thedisplay panel 10 and that between theadhesive structure 18 and theframe 12, such that the chances of theadhesive structures 18 being separated (peeled off) from theframe 12 and/or thedisplay panel 10, thereby improving the strength of the overall structure of thedisplay device 1 at the non-room temperature. - In some embodiments, a height H3 of the protruding
structure 19 relative to thetop surface 120 t of theframe 12 is substantially equal to or is lower than the height H2 of thedisplay panel 10 relative to thetop surface 120 t of theframe 12. In some embodiments, the height H3 of the protrudingstructure 19 relative to thetop surface 120 t of theframe 12 is lower than the height H2 of thedisplay panel 10 relative to thetop surface 120 t of theframe 12. - In some embodiments, the height H3 of the protruding
structure 19 relative to thetop surface 120 t of theframe 12 is higher than thesidewall 160 of thehousing 16, but the present disclosure is not limited thereto. For example, a height of the protrudingstructure 19 relative to thetop surface 120 t of theframe 12 may be substantially equal to thesidewall 160 of thehousing 16. In some embodiments, an area of a vertical projection of the protrudingstructures 19 on thetop surface 120 t of theframe 12 is smaller than about one half of the area of thetop surface 120 t, but the present disclosure is not limited thereto. - In some embodiments, the protruding
structure 19 hasside surface 192. Theside surface 192 of the protrudingstructure 19 is not in contact with the adhesive structure 18 (seeFIG. 3A ). In addition, a portion of theframe 12 between the two adjacent protrudingstructures 19 is not in contact with the adhesive structure 18 (seeFIG. 3A ). - In
FIG. 3B , theadhesive structure 18 as shown inFIG. 3A is sequentially adhered to thedisplay surface 106 of thedisplay panel 10, atop surface 190 t of the protrudingstructure 19 located away from theframe 12, theside surface 160 s of thesidewall 160, and thebottom plate 162 of thehousing 16. The thickness T (seeFIG. 3A ) of theadhesive structure 18 is smaller than the height H3 of the protrudingstructure 19 relative to theframe 12. - In
FIG. 2A andFIG. 3B , thebacklight module 15 is disposed between thebottom plate 162 of thehousing 16 and the supportingportion 122 of theframe 12. Thebacklight module 15 sequentially includes alight guiding plate 150 and anoptical film 152 from thebottom plate 162 to the supportingportion 122. Thebacklight module 15 further includesreflective layer 154. Thereflective layer 154 covers thelight guiding plate 150 and a sidewall of theoptical film 152. The supportingportion 122 of theframe 12 covers theouter edge 152 of theoptical film 152. - In some embodiments, the light source (not shown) is disposed on the
sidewall 120 of theframe 12 and is configured to provide light toward thelight guiding plate 150, but the present disclosure is not limited thereto. In other embodiments, thelight source 15 also may be placed at a desired position according to design requirements. The light of thelight source 15 is guided by thelight guiding plate 150 to provide the surface light source to thedisplay panel 10. Theoptical film 152 may be a diffusion film, a brightness enhancement film, a composite film, or combination thereof. Thereflective layer 154 is configured to reflect the light emitted by the light source to thedisplay panel 10, thereby improving the luminous efficiency of thedisplay panel 10. - Reference is made to
FIG. 4A .FIG. 4A is cross-sectional views ofadhesive structure 18 in accordance with some embodiments of the present disclosure. As shown inFIG. 4A , in some embodiments, theadhesive structure 18 includes anadhesive layer 180, afirst molding layer 182, anelectromagnetic shielding layer 184, and an insulatinglayer 188 which are sequentially stacked on each other. Theadhesive layer 180 in theadhesive structure 18 is adhered to thedisplay surface 106 of thedisplay panel 10, thetop surface 140 t of the protrudingstructure 14 located away from theframe 12, theside surface 160 s of thesidewall 160, and thebottom plate 162 of thehousing 16 as shown inFIGS. 2A and 2B . - In some embodiments, the
adhesive layer 180 in theadhesive structure 18 may be made of material including conductive adhesive. Thefirst molding layer 182 of theadhesive structure 18 may include fiber structure. In some embodiments, thefirst molding layer 182 may include plant fibres. For example, thefirst molding layer 182 is impregnated with a fiber or a fiber cloth in a thermoplastic resin to form an impregnated discontinuous fiber cloth so that the thermoplastic resin fills the gap of the discontinuous fiber or the fiber cloth, and covers the entire surface of the continuous fiber cloth. Thereby, thefirst molding layer 182 may improve the conformability of theadhesive structure 18 on thedisplay panel 10, the protrudingstructure 14 and thehousing 16, such that the chances of theadhesive structures 18 being separated from thedisplay panel 10, the protrudingstructure 14, and/or thehousing 16 may be reduced. - In some embodiments, the
electromagnetic shielding layer 184 of theadhesive structure 18 may be made of material including metal or any material that may be used as electromagnetic shielding. For example, theelectromagnetic shielding layer 184 may include aluminum. The insulatinglayer 188 of theadhesive structure 18 may include insulating material. For example, the insulatinglayer 188 may include polyethylene terephthalate (PET). Thereby, the insulatinglayer 188 in theadhesive structure 18 may insulate theelectromagnetic shielding layer 184 or theadhesive layer 180 from other components, thereby preventing thedisplay device 1 from being short-circuited. - Reference is made to
FIG. 4B .FIG. 4B is a cross-sectional view ofadhesive structure 28 in accordance with some embodiments of the present disclosure. As shown inFIG. 4A , in some embodiments, theadhesive structure 18 includes theadhesive layer 180, thefirst molding layer 182, theelectromagnetic shielding layer 184, a second molding layer 286, and the insulatinglayer 188 which are sequentially stacked on each other. The structure and function of the components and their relationships are substantially the same as theadhesive structure 18 shown inFIG. 4A , and the related detailed descriptions may refer to the foregoing paragraphs, and are not described again herein. It is noted that, the difference between the present embodiment and the embodiment inFIG. 4A is in that theadhesive structure 28 further includes the second molding layer 286. The second molding layer 286 of theadhesive structure 28 is disposed between theelectromagnetic shielding layer 184 and the insulatinglayer 188. Thereby, the second molding layer 286 may further improve the conformability of theadhesive structure 28 on thedisplay panel 10, the protrudingstructure 14 and thehousing 16, such that the chances of theadhesive structures 28 being separated (peeled off) from thedisplay panel 10, the protrudingstructure 14, and/or thehousing 16 may be reduced. - Reference is made to

inner edge 126 n of theopening 126. In some embodiments, a distance between the protruding structure 24 and theouter edge 120 p of thetop surface 120 t of thesidewall 120 is greater than the width W4, but the present disclosure is not limited thereto. For example, the distance between the protruding structure 24 and theouter edge 120 p of thetop surface 120 t of thesidewall 120 may be about twice the width W4. In some embodiments, an area of a vertical projection of the protruding structures 24 on thetop surface 120 t of theframe 12 is smaller than about one half of an area of thetop surface 120 t, but the present disclosure is not limited thereto.

FIG. 7B , the protrudingstructure 29 has a width W5 in a direction substantially perpendicular to theouter edge 120 p. In some embodiments, a distance between the protrudingstructure 29 and theinner edge 126 n of theopening 126 is greater than about the width W5, but the present disclosure is not limited thereto. For example, the distance between the protrudingstructure 29 and theinner edge 126 n of theopening 126 may be about twice the width W5. - In some embodiments, a height H5 of the protruding
structure 29 relative to thetop surface 120 t of theframe 12 is substantially equal to or is lower than the height H2 of thedisplay panel 10 relative to thetop surface 120 t of theframe 12. In some embodiments, the height H5 of the protrudingstructure 29 relative to thetop surface 120 t of theframe 12 is lower than the height H2 of thedisplay panel 10 relative to thetop surface 120 t of theframe 12. - In

structure 29 has aside surface 292. Theside surface 292 of the protrudingstructure 29 is not in contact with the adhesive structure 18 (seeFIG. 7A ). In addition, a portion of theframe 12 between two adjacent protrudingstructures 29 is not in contact with the adhesive structure 18 (seeFIG. 7A ). - In some embodiments, the height H5 of the protruding
structure 29 relative to thetop surface 120 t of theframe 12 is higher than thesidewall 160 of thehousing 16, but the present disclosure is not limited thereto. For example, a height of the protrudingstructure 29 relative to thetop surface 120 t of theframe 12 may be substantially equal to thesidewall 160 of thehousing 16. In some embodiments, an area of a vertical projection of the protrudingstructures 29 on thetop surface 120 t of theframe 12 is smaller than about one half of the area of thetop surface 120 t, but the present disclosure is not limited thereto. - In some embodiments, the
adhesive structure 18 simultaneously covers thedisplay panel 10, the protruding structure 24, and/or the protrudingstructure 29 on theframe 12, such that thedisplay panel 10 is connected to theframe 12 by theadhesive structure 18. Therefore, a contact area between theadhesive structure 18 and theframe 12 may be reduced by the protruding structure 24 and/or the protrudingstructure 29 on theframe 12, so as to reduce the difference between a contact area between theadhesive structure 18 and thedisplay panel 10 and that between theadhesive structure 18 and theframe 12, such that the chances of theadhesive structures 18 being separated (peeled off) from theframe 12 and/or thedisplay panel 10, thereby improving the strength of the overall structure of thedisplay device 2 at the non-room temperature. - Reference is made to
FIGS. 8, 9A, and 9B .FIG. 8 is a partial perspective view of adisplay device 3 in accordance with some embodiments of the present disclosure, in whichFIG. 8 omits theadhesive structure 18 as shown inFIG. 1A .FIG. 9A is a partial perspective cross-sectional view taken along abroken line 9 inFIG. 8 , in whichFIG. 9A further includes theadhesive structure 18 as shown inFIG. 1A in comparison with toFIG. 5 .FIG. 9B is a partial perspective cross-sectional view taken along thebroken line 9 inFIG. 8 . - In some embodiments, the

The structure and function of the components and their relationships are substantially the same as those of thedisplay device 1 and theadhesive structure 18 shown inFIGS. 1A to 3B , and the related detailed descriptions may refer to the foregoing paragraphs, and are not described again herein. - It is noted that, the difference between the present embodiment and the embodiment in
FIGS. 1A to 3B is in that the protrudingstructure 34 as shown inFIG. 9B is a strip protrusion along theinner edge 126 n of theopening 126 of theframe 12. The protrudingstructure 34 as shown inFIG. 9B is a strip protrusion extending along a first direction D1 intersecting theinner edge 126 n of theopening 126 of theframe 12. The protrudingstructure 34 extends from theinner edge 126 n of theopening 126 to theouter edge 120 p of thetop surface 120 t of thesidewall 120. In addition, the protrudingstructure 39 as shown inFIG. 9B is a strip protrusion extending along a first direction D2 intersecting theinner edge 126 n of theopening 126 of theframe 12. The protrudingstructure 39 extends from theinner edge 126 n of theopening 126 to theouter edge 120 p of thetop surface 120 t of thesidewall 120. - In some embodiments, the first direction D1 intersects an extending direction N of the

The second direction D2 intersects an extending direction N of theinner edge 126 n of theopening 126 of theframe 12 at a first angle A2. The first angle A1 is substantially equal to the second angle A2. Therefore, the present embodiment replaces the protruding structured 14 as shown inFIGS. 1A to 3B with the protrudingstructure 34 and the protrudingstructure 39 and/or replaces the protruding structured 19 as shown inFIGS. 1A to 3B with the protrudingstructure 34 and the protrudingstructure 39. - Further, in

structure 34 and/or the protrudingstructure 39 relative to thetop surface 120 t of theframe 12 is higher than thesidewall 160 of thehousing 16 relative to thetop surface 120 t of theframe 12, but the present disclosure is not limited thereto. For example, the height H6 of the protrudingstructure 34 and/or the protrudingstructure 39 relative to thetop surface 120 t of theframe 12 may be substantially equal to thesidewall 160 of thehousing 16 relative to thetop surface 120 t of theframe 12. - In
FIG. 9B , theadhesive structure 18 as shown inFIG. 9A is sequentially adhered to thedisplay surface 106 of thedisplay panel 10,top surfaces 340 t and 390 t of the protrudingstructures frame 12, theside surface 160 s of thesidewall 160, and thebottom plate 162 of thehousing 16. The thickness T (seeFIG. 6A ) of theadhesive structure 18 is smaller than the height H6 of the protrudingstructures frame 12. - In some embodiments, the protruding
structures side surfaces structures FIG. 6A ). In addition, a portion of theframe 12 between the two adjacent protrudingstructures 34 is not in contact with the adhesive structure 18 (seeFIG. 6A ) and another portion of theframe 12 between the two adjacent protrudingstructures 39 is not in contact with the adhesive structure 18 (seeFIG. 6A ). - In some embodiments, the protruding
structure 34 has a width W6 in a direction substantially perpendicular to the first direction D1. Alternatively, the protrudingstructure 39 has the width W6 in a direction substantially perpendicular to the second direction D2. In some embodiments, a distance between two adjacent protrudingstructures 34 is greater than about the width W6 and/or another distance between two adjacent protrudingstructures 39 is greater than about the width W6, but the present disclosure is not limited thereto. For example, the distance between the two adjacent protrudingstructures 34 may be about twice of the width W6 and/or the other distance between the two adjacent protrudingstructures 39 may be about twice of the width W6. In some embodiments, an area of a vertical projection of the protrudingstructures 34 and the protrudingstructures 39 on thetop surface 120 t of theframe 12 is smaller than about one half of an area of thetop surface 120 t, but the present disclosure is not limited thereto. For example, the area of the vertical projection of the protrudingstructures 34 and the protrudingstructures 39 on thetop surface 120 t of theframe 12 may be about one third of the area of thetop surface 120 t. - In some embodiments, the
adhesive structure 18 simultaneously covers thedisplay panel 10, the protrudingstructure 34, and the protrudingstructure 39 on theframe 12, such that thedisplay panel 10 is connected to theframe 12 by theadhesive structure 18. Therefore, a contact area between theadhesive structure 18 and theframe 12 may be reduced by the protrudingstructure 34 and the protrudingstructure 39 on theframe 12, so as to reduce the difference between a contact area between theadhesive structure 18 and thedisplay panel 10 and that between theadhesive structure 18 and theframe 12, such that the chances of theadhesive structures 18 being separated (peeled off) from theframe 12 and/or thedisplay panel 10, thereby improving the strength of the overall structure of thedisplay device 3 at the non-room temperature. - According to the foregoing embodiments of the disclosure, it may be seen that, the adhesive structure simultaneously covers the display panel and the protruding structure on the frame, such that the display panel is connected to the frame by the adhesive structure. Since the thermal expansion coefficient of the frame is different from the thermal expansion coefficient of the display panel, when the display device is at the non-room temperature, the frame and the display panel may push against each other through the adhesive structure, thus breaking a connection between the display panel, the frame and/or the adhesive structure. In some embodiments, a contact area between the adhesive structure and the frame may be reduced by the protruding structure on the frame, so as to reduce the difference between a contact area between the adhesive structure and the display panel and that between the adhesive structure and the frame, such that the chances of the adhesive structure being separated (peeled off) from the frame and/or the display panel may be reduced, thereby improving the strength of the overall structure of the display device at the non-room temperature.
- The foregoing outlines features of several embodiments so that those skilled in the art may better understand the aspects of the present disclosure. Those skilled in the art should appreciate that they may readily use the present disclosure as a basis for designing or modifying other processes and structures for carrying out the same purposes and/or achieving the same advantages of the embodiments introduced herein. Those skilled in the art should also realize that such equivalent constructions do not depart from the spirit and scope of the present disclosure, and that they may make various changes, substitutions, and alterations herein without departing from the spirit and scope of the present disclosure.
