[0082] In the accompanying drawings, the thicknesses of layers, films, panels, regions, etc., are enlarged for clarity. Throughout the specification, the same reference numerals denote the same elements. It should be understood that when an element such as a layer, film, region, or substrate is referred to as being "on" or "connected" to another element, it may be directly on or connected to the other element, or intermediate elements may also be present. Conversely, when an element is referred to as being "directly on" or "directly connected" to another element, no intermediate elements are present. As used herein, "connection" can refer to a physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" may mean that other elements exist between the two elements.
[0083] It should be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or parts, these elements, components, regions, layers, and / or parts should not be limited by these terms. These terms are used only to distinguish one element, component, region, layer, or part from another. Therefore, the first “element,” “component,” “region,” “layer,” or “part” discussed below may be referred to as a second element, component, region, layer, or part without departing from the teachings of this document.
[0084] The terminology used herein is for the purpose of describing particular embodiments only and is not restrictive. As used herein, unless the content clearly indicates otherwise, the singular forms “a,” “an,” and “the” are intended to include the plural forms, including “at least one” or denoteing “and / or.” As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. It should also be understood that, when used in this specification, the terms “comprising” and / or “including” specify the presence of the stated features, areas, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, areas, integrals, steps, operations, elements, components, and / or combinations thereof.
[0085] Furthermore, relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship between one element and another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one figure is flipped, an element described as being “down” to other elements will be oriented “up” to other elements. Thus, the exemplary term “down” can include both “down” and “up” orientations, depending on the specific orientation of the figure. Similarly, if a device in one figure is flipped, an element described as being “down” or “below” to other elements will be oriented “above” to other elements. Thus, the exemplary terms “down” or “below” can include both “up” and “down” orientations.
[0086] Given the specific number of measurements discussed and the associated errors (i.e., limitations of the measurement system), the terms "about," "approximately," or "substantially" as used herein include the value and the average value within an acceptable range of deviations from the specific value as determined by one of ordinary skill in the art. For example, "about" may mean within one or more standard deviations of the value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, the terms "about," "approximately," or "substantially" as used herein may be chosen based on the optical, etched, or other properties to select a more acceptable range of deviations or standard deviations, rather than applying a single standard deviation to all properties.
[0087] 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 invention pertains. It will be further understood that terms such as those defined in commonly used dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant technology and this invention, and will not be interpreted as having idealized or overly formal meanings unless expressly defined herein.
[0088] This document describes exemplary embodiments with reference to cross-sectional views, which are schematic diagrams of idealized embodiments. Therefore, variations in shape as a result of, for example, manufacturing techniques and / or tolerances, are expected in the illustrations. Consequently, the embodiments described herein should not be construed as limited to the specific shapes of the regions shown herein, but rather include, for example, shape deviations caused by manufacturing processes. For example, regions shown or described as flat may generally have rough and / or non-linear characteristics. Furthermore, the acute angles shown may be rounded. Therefore, the regions shown in the figures are schematic in nature, and their shapes are not intended to show the precise shapes of the regions, nor are they intended to limit the scope of the claims.

[0090] Please refer to Figures 1A to 1F The display device 10 includes a light source module 110, a housing 120, a display panel 130, a circuit board 140, and a first flexible substrate 115. The housing 120 is located below the light source module and includes a base plate 121, sidewalls 122, and a support portion 123. The sidewalls 122 are connected to the base plate 121 to form an accommodating space AS for accommodating the light source module 110. The support portion 123 is connected to the sidewalls 122 and extends away from the sidewalls 122, wherein the support portion 123 has at least one recess ES recessed into the extending plane of the base plate 121. The number of recesses ES should correspond to the number of first flexible substrates 115; two are used as an example here. The display panel 130 is located above the light source module 110 and the support portion 123 of the housing 120. The circuit board 140 is located below the support portion 123 of the housing 120, and the support portion 123 of the housing 120 is located between the display panel 130 and the circuit board 140. The first flexible substrate 115 connects the light source module 110 and the circuit board 140 through the groove ES of the support portion 120, wherein one side of the groove ES supports the display panel 130 and the other side of the groove ES supports the circuit board 140.
[0091] In a display device 10 according to an embodiment of the present invention, by supporting the display panel 130 on one side of the recess ES and the circuit board 140 on the opposite side of the recess ES, the overall structural stability of the display device 10 can be improved, thereby reducing the possibility of breakage and improving product yield. Hereinafter, in conjunction with... Figures 1A to 1F The embodiments of the various components of the display device 10 will be described further, but the present invention is not limited thereto.
[0092] In the display device 10, the light source module 110 may be located between the housing 120 and the display panel 130. In some embodiments, the light source module 110 includes a substrate 112 and a light source 114 disposed on the substrate 112. In some embodiments, the light source 114 is an array of light-emitting diodes (LEDs). In some embodiments, the light source 114 includes mini-LEDs or micro-LEDs. In some embodiments, the light source 114 may also include a light-transmitting sealant covering the LEDs.
[0093] In some embodiments, the light source module 110 further includes an optical film 116, which is located between the light source 114 and the display panel 130. For example, the optical film 116 may include a polarizer, a diffuser, a prism, a composite optical film, or a combination thereof, to adjust the uniformity of the emitted light from the light source module 110; a direct-lit light source module is used as an example here. Additionally, when the light source module 110 is a side-lit light source module, it may also include a light guide plate.
[0094] In some embodiments, the sidewall 122 of the housing 120 connects the base plate 121 and the support portion 123. In some embodiments, the base plate 121, the sidewall 122, and the support portion 123 are integrally formed. In some embodiments, the sidewall 122 is substantially perpendicular to the extension surface of the base plate 121, such that when the light source module 110 is accommodated in the accommodating space AS surrounded by the base plate 121 and the sidewall 122, it can be adjacent to the extension surface of the base plate 121 and the extension surface of the sidewall 122. In some embodiments, the extension surface of the support portion 123 is substantially perpendicular to the extension surface of the sidewall 122.
[0095] In some embodiments, the support portion 123 and the base plate 121 are respectively connected to two opposite sides of the side wall 122, and both the support portion 123 and the base plate 121 extend away from the side wall 122. In some embodiments, the support portion 123 and the base plate 121 extend away from the side wall 122 in different directions. In some embodiments, the extending plane of the support portion 123 is parallel to the extending plane of the base plate 121. In some embodiments, the groove ES of the support portion 123 is formed by recessing inward from the extending plane of the support portion 123 toward the extending plane of the base plate 121. In some embodiments, the support portion 123 of the housing 120 has opposing top surfaces FT and back surfaces FB, and the groove ES is formed by recessing a portion of the top surface FT of the support portion 123 toward the back surface FB. In some embodiments, the bottom surface BS of the groove ES is substantially parallel to the extending plane of the support portion 123 or the extending plane of the base plate 121.
[0096] In some embodiments, the support portion 123 extends from the sidewall 122 along a first direction D1 in a direction away from the base plate 121, and the groove ES is recessed along a second direction D2, wherein the first direction D1 is different from the second direction D2. In some embodiments, the long side of the support portion 123 extends along a third direction D3, wherein the third direction D3 is different from both the first direction D1 and the second direction D2. In some embodiments, the third direction D3 is substantially perpendicular to the first direction D1 and substantially perpendicular to the second direction D2. For example, the extension surface of the support portion 123 extends along the first direction D1 and the third direction D3, and the groove ES is formed by a portion of the extension surface of the support portion 123 being recessed in the second direction D2, wherein the second direction D2 is the direction from the extension plane of the support portion 123 to the extension plane of the base plate 121. In some embodiments, the second direction D2 is substantially perpendicular to the extension plane of the support portion 123 and the extension plane of the base plate 121.
[0097] In some embodiments, there is a first distance S1 between the base plate 121 and the display panel 130, a second distance S2 between the support portion 123 and the display panel 130, and a third distance S3 between the bottom surface BS of the groove ES and the display panel 130, wherein the first distance S1 is greater than the third distance S3 and the third distance S3 is greater than the second distance S2, i.e., S1>S3>S2.
[0098] The display panel 130 of the display device 10 may be a liquid crystal display (LCD), but the present invention is not limited thereto. In some embodiments, the display panel 130 has a display area AA and a peripheral area AP, and the light source 114 of the light source module 110 overlaps the display area AA of the display panel 130. That is, the light source module 110 is a direct-lit light source module, but the present invention is not limited thereto. In some embodiments, when the light source module 110 is a side-lit light source module, the light source 114 of the light source module 110 may overlap the peripheral area AP of the display panel 130.
[0099] The circuit board 140 of the display device 10 may be adjacent to the back surface FB of the support portion 123. In some embodiments, the circuit board 140 has opposing first surfaces F1 and second surfaces F2, and a side surface F3 connecting the first surface F1 and the second surface F2, and the second surface F2 of the circuit board 140 faces the support portion 123 of the housing 120. In some embodiments, a first flexible substrate 115 surrounds the second surface F2, the side surface F3, and the first surface F1 of the circuit board 140, and the first flexible substrate 115 is connected to the first surface F1 of the circuit board 140. In some embodiments, the first flexible substrate 115 sequentially passes through the second surface F2, the side surface F3, and the first surface F1 of the circuit board 140.
[0100] Please refer to Figure 1C In some embodiments, the first flexible substrate 115 is housed in the groove ES of the support portion 123, and the groove ES is located between the first flexible substrate 115 and the circuit board 140. In some embodiments, the depth H1 of the groove ES is greater than or equal to the thickness H2 of the first flexible substrate 115. In some embodiments, the width W1 of the groove ES along the third direction D3 is greater than or equal to the width W2 of the first flexible substrate 115. In some embodiments, the width W1 of the groove ES is approximately the same along the first direction D1; in other words, the groove ES has a rectangular top view shape, but the invention is not limited thereto. In some embodiments, the bottom surface BS of the groove ES is a plane or a curved surface. Since the bottom surface BS of the groove ES, together with the first flexible substrate 115, can support the display panel 130, and the back surface FB of the groove ES can support the circuit board 140, the overall structural stability of the display device 10 is improved, thereby reducing the possibility of fragmentation. In some embodiments, when the display device 10 is a curved display, the continuous structure of the housing 120 can improve the strength and stability of the overall curved structure.
[0101] Please refer to the following at the same time Figure 1D and Figure 1FIn some embodiments, the first flexible substrate 115 includes a light source connection portion 115a, a circuit connection portion 115b, and a bending portion 115c, wherein the bending portion 115c connects the light source connection portion 115a and the circuit connection portion 115b. In some embodiments, the light source connection portion 115a of the first flexible substrate 115 is connected to the light source module 110, and the circuit connection portion 115b of the first flexible substrate 115 is connected to the circuit board 140. In some embodiments, the light source connection portion 115a is disposed on the bottom surface 112b of the substrate 112 of the light source module 110, and the light source 114 is disposed on the top surface 112a of the substrate 112, wherein the top surface 112a and the bottom surface 112b are opposite to each other. In other words, the light source connection portion 115a and the light source 114 are respectively disposed on two opposite sides of the substrate 112. In this way, the first flexible substrate 115 can be prevented from covering the top surface 112a of the substrate 112 and affecting the light emission of the light source 114, so as to avoid adverse effects on the display area AA of the display panel 130.
[0102] Please refer to Figures 1C to 1E In some embodiments, the display device 10 further includes a first adhesive member AH1, which covers the top surface FT of the support portion 123 to fix the display panel 130 to the housing 120. In some embodiments, the first adhesive member AH1 extends continuously along a third direction D3, passes over the groove ES of the support portion 123, and is continuously disposed on the top surface FT of the support portion 123 to facilitate its attachment, but the present invention is not limited thereto. In some embodiments, the first adhesive member AH1 is located between the display panel 130 and the support portion 123 of the housing 120.
[0103] In some embodiments, the first flexible substrate 115 of the display device 10 is located between the first adhesive AH1 and the bottom surface BS of the groove ES, such that the bottom surface BS of the groove ES accommodating the first flexible substrate 115 supports the bottom surface 130B of the display panel 130 by abutting against the first adhesive AH1. In other words, the bottom surface BS of the groove ES abuts against the first flexible substrate 115 within the groove ES, and thus indirectly abuts against the first adhesive AH1, thereby supporting the display panel 130. In some embodiments, the first flexible substrate 115 is a flexible printed circuit board (FPC).
[0104] Please refer to Figure 1C and Figure 1EIn some embodiments, the display device 10 further includes a second adhesive AH2, which covers the back surface FB of the support portion 123 to secure the circuit board 140 to the housing 120. In some embodiments, the second adhesive AH2 extends discontinuously past the groove ES of the support portion 123, but is provided at intervals on the back surface FB of the support portion 123. In some embodiments, the back surface FB of the groove ES of the support portion 123 abuts against the circuit board 140 to support the circuit board 140 together with the second adhesive AH2. In some embodiments, the second adhesive AH2 is located between the circuit board 140 and the support portion 123 of the housing 120, and the sum of the thickness of the second adhesive AH2 and the thickness of the support portion 123 of the housing 120 is substantially equal to the sum of the thickness of the first flexible substrate 115 and the thickness of the bottom of the groove ES. In some embodiments, the thickness of the bottom of the groove ES is substantially equal to the thickness of the support portion 123. In some embodiments, the thickness of the first flexible substrate 115 is substantially equal to the thickness of the second adhesive AH2.
[0105] Please refer to Figure 1F In some embodiments, the display device 10 further includes a second flexible substrate 135. In some embodiments, the second flexible substrate 135 includes a panel connection portion 135a, a circuit connection portion 135b, and a bending portion 135c, wherein the bending portion 135c connects the panel connection portion 135a and the circuit connection portion 135b. In some embodiments, the panel connection portion 135a of the second flexible substrate 135 is connected to the display panel 130, and the circuit connection portion 135b of the second flexible substrate 135 is connected to the circuit board 140.
[0106] In some embodiments, the second flexible substrate 135 surrounds the second surface F2, the side surface F3, and the first surface F1 of the circuit board 140. In some embodiments, the second flexible substrate 135 sequentially passes through the second surface F2, the side surface F3, and the first surface F1 of the circuit board 140, and the second flexible substrate 135 is connected to the first surface F1 of the circuit board 140. In some embodiments, the second flexible substrate 135 is a flexible printed circuit board.
[0107] In some embodiments, the second surface F2 of the circuit board 140 remains flat to facilitate attachment to the carrier portion 123, and the first surface F1 of the circuit board 140 has space for accommodating electronic components. For example, the display device 10 further includes a connector CR and an electronic component CP, and the connector CR and the electronic component CP can be disposed on the first surface F1 of the circuit board 140. In some embodiments, the circuit connection portion 135b of the second flexible substrate 135 is bonded to the first surface F1 of the circuit board 140. In some embodiments, the circuit connection portion 115b of the first flexible substrate 115 is connected to the connector CR located on the first surface F1 of the circuit board 140. In some embodiments, the electronic component CP includes a power board, a driver board, a timing control circuit (TCON), an display control circuit (AD board), and an intelligent display module (SDM), etc.
[0108] In some embodiments, the assembly steps of the display device 10 include: connecting the panel connection portion 135a of the second flexible substrate 135 to the display panel 130, and connecting the circuit connection portion 135b of the second flexible substrate 135 to the circuit board 140; inserting the circuit connection portion 115b of the first flexible substrate 115 into the connector CR; and folding the circuit board 140 onto the back surface FB of the support portion 123. In some embodiments, folding the circuit board 140 onto the back surface FB of the support portion 123 is achieved by bending the bending portions 115c of the first flexible substrate 115 and the bending portions 135c of the second flexible substrate 135. By folding the circuit board 140 onto the back surface FB of the support portion 123, the circuit board 140 is stacked with the support portion 123, thereby reducing the bezel of the display device 10.
[0109] Please refer to Figure 1F In some embodiments, after the circuit board 140 is folded onto the back surface FB of the support portion 123, the circuit connection portion 135b of the second flexible substrate 135 is further away from the sidewall 122 of the housing 120 than the circuit connection portion 115b of the first flexible substrate 115. In other words, before the circuit board 140 is folded onto the back surface FB of the support portion 123, the connector CR is disposed on the circuit board 140 at a location further away from the sidewall 122 than the point where the circuit board 140 engages with the circuit connection portion 135b, to avoid the connector CR obstructing the connection of the circuit connection portion 135b to the circuit board 140.
[0110] Please refer to Figure 1B In some embodiments, the first flexible substrate 115 overlaps the second flexible substrate 135, and the first flexible substrate 115 and the second flexible substrate 135 are side by side in the second direction D2. In this way, the central area of the first surface F1 of the circuit board 140 can have a relatively large space for electronic component configuration.
[0111] The following uses Figures 2 to 3 Further embodiments of the present invention will be described, and the following will be used... Figures 1A to 1F The component designations and related content of the embodiments are as follows: the same designations are used to represent the same or similar components, and descriptions of identical technical content are omitted. For explanations of the omitted parts, please refer to... Figures 1A to 1F The embodiments described below will not be repeated.
[0112] Figure 2 This is a cross-sectional schematic diagram of a display device 20 according to an embodiment of the present invention. (The last sentence appears to be incomplete and possibly contains errors.) Figures 1A to 1F Compared to the display device 10 shown, Figure 2 The main difference in the display device 20 is that the first adhesive AH1 of the display device 20 extends discontinuously along the third direction D3, bypassing the groove ES of the support portion 123, so that the first adhesive AH1 is not present between the first flexible substrate 115 and the display panel 130. In this way, the first flexible substrate 115 is not covered by the first adhesive AH1, and the bottom surface BS of the groove ES accommodating the first flexible substrate 115 can support the display panel 130 by abutting against the first flexible substrate 115. This avoids the first adhesive AH1 from adhering to the first flexible substrate 115, thus facilitating rework. In some embodiments, the depth H1 of the groove ES may also be less than the thickness H2 of the first flexible substrate 115 to ensure that the first flexible substrate 115 can effectively support the bottom surface 130B of the display panel 130.
[0113] In some embodiments, the display device 20 further includes a third adhesive member AH3, which is located between the first flexible substrate 115 and the bottom surface BS of the groove ES. The third adhesive member AH3 can be used to fix the first flexible substrate 115 and adjust its height. Furthermore, by fixing the first flexible substrate 115 to the bottom surface BS of the groove ES via the third adhesive member AH3, it is possible to prevent the first flexible substrate 115 from protruding outside the groove ES and lifting the display panel 130 due to the rigidity of its material, thus avoiding uneven stress on the display panel 130.
[0114] In some embodiments, the back surface FB of the recess ES serves as the ground terminal of the display device 20. In some embodiments, the display device 20 further includes a fourth adhesive AH4, which is located between the back surface FB of the recess ES and the circuit board 140. In some embodiments, the fourth adhesive AH4 is conductive to electrically connect the circuit board 140 to the ground terminal of the display device 20.
[0115] Figure 3 This is a partial perspective view of the housing 320 of a display device according to an embodiment of the present invention. Figures 1A to 1F Compared to the housing 120 of the display device 10 shown, Figure 3 The main difference of the housing 320 shown is that the housing 320 includes a base plate 121, a side wall 122, and a support portion 323, and the groove ESa of the support portion 323 of the housing 320 has a trapezoidal top view shape. In some embodiments, when the width of the first flexible substrate 115 decreases from wide to narrow along the first direction D1, the width W1 of the groove ESa can also decrease from wide to narrow along the first direction D1, so as to accommodate the first flexible substrate 115 within the groove ESa.
[0116] In summary, the display device of the present invention supports the display panel on one side of the groove and the circuit board on the other side of the groove ES, which can improve the structural stability of the display device and reduce the possibility of breakage, thereby improving the product yield.
[0117] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Those skilled in the art can make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
