Description

Technical Field

[0001] This invention relates to a display device, and more particularly to a display device including a backlight module. Background Technology

[0002] Generally, the backlight module accounts for a large proportion of the overall cost of a display component. To reduce costs, the versatility of components can be improved. However, traditionally, the shared design of the frame can lead to insufficient frame strength due to the different spacing of the driver chips on the flexible substrate, resulting in light leakage and dust intrusion. Summary of the Invention

[0003] The present invention provides a display device that can improve the assembly strength of the frame.

[0004] The display device of the present invention includes a display panel, a backlight module, and a frame. The display panel is disposed on the backlight module and includes a light guide layer and a support. The light guide layer has adjacent light-incident side and bottom side. The support carries the light guide layer and includes a first segment corresponding to the light-incident side, a second segment corresponding to the bottom side, and a transition segment located between the first segment and the second segment. The frame is located at the periphery of the backlight module and includes a first inner surface corresponding to the first segment, a second inner surface corresponding to the second segment, and a first inclined surface and a second inclined surface located between the first inner surface and the second inner surface. The first inclined surface and the second inclined surface are connected to each other and correspond to the transition segment.

[0005] In one embodiment of the present invention, the inclination of the first inclined surface of the frame is greater than the inclination of the second inclined surface.

[0006] In one embodiment of the present invention, the light guide layer further has a light emitting side, the bottom side and the light emitting side are opposite to each other, the display panel corresponds to the light emitting side, and the frame has a first part, a second part and a third part connected to each other and respectively corresponding to the light-incident side, the bottom side and the light emitting side of the light guide layer.

[0007] In one embodiment of the present invention, the first part of the frame has a recess near the third part, and the end of the first segment of the bracket engages with the recess.

[0008] In one embodiment of the present invention, the end of the first segment of the bracket is bent, and the end of the first segment faces away from the third segment.

[0009] In one embodiment of the present invention, the end of the first segment of the bracket is straight, and the end of the first segment faces the third segment.

[0010] In one embodiment of the invention, the inner surface of the third part of the frame described above has an inclined surface or a plane.

[0011] In one embodiment of the present invention, the outer surface of the second part of the frame described above has a positioning portion.

[0012] In one embodiment of the present invention, the first, second and third portions of the frame are U-shaped.

[0013] In one embodiment of the present invention, the backlight module further includes a heat sink located between the light guide layer and the bracket.

[0014] Based on the above, in the display device of the present invention, the support of the backlight module includes a transition section. The frame includes a first inclined surface and a second inclined surface corresponding to the transition section. Through the design of the first and second inclined surfaces, during the assembly of the frame and the backlight module, the frame can generate an automatic inward flipping force near the upper part of the display panel to prevent it from tilting, thus solving the problems of light leakage and dust intrusion, and giving the frame better stability and strength.

[0015] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings. Attached Figure Description

[0056] The invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are illustrated. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention.

[0057] 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 physical and / or electrical connection. Furthermore, "electrical connection" or "coupling" may mean that other elements exist between the two elements.

[0058] 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 “below” or “under” other elements will be oriented “above” other elements. Thus, the exemplary terms “above” or “below” can include both “up” and “down” orientations.

[0059] As used herein, “about,” “approximately,” or “substantially” includes the value and the average value within an acceptable range of deviations from a particular value as determined by one of ordinary skill in the art, taking into account the measurement under discussion and a particular number of errors associated with the measurement (i.e., limitations of the measurement system). For example, “about” may mean within one or more standard deviations of the value, or within ±30%, ±20%, ±10%, ±5%. Furthermore, the use of “about,” “approximately,” or “substantially” herein may be chosen based on the optical, etched, or other properties to select a more acceptable range of deviations or standard deviations, and may not require a single standard deviation to apply to all properties.

[0060] This document describes exemplary embodiments with reference to cross-sectional views, which are schematic diagrams of idealized embodiments. Therefore, variations in the shape of the illustrations can be expected as a result of, for example, manufacturing techniques and / or tolerances. 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, 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 protection claimed by the invention.

[0061] 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.

[0062] The X, Y, and Z directions are marked in the drawings to show the configuration relationship of the components in the drawing. The X, Y, and Z directions intersect each other, but are not required to be orthogonal to each other.

[0063] Figure 1 This is an exploded view of a display device according to an embodiment of the present invention. Please refer to it. Figure 1 The display device 100 of this embodiment includes a display panel 110, a backlight module 120, and a frame 130. The display panel 110 is disposed on the backlight module 120. The backlight module 120 includes a light guide layer 121, a bracket 122, and a heat sink 123. The heat sink 123 is located between the light guide layer 121 and the bracket 122. In addition, the display device 100 also includes a front frame and a back cover, etc., which are not limited by the present invention. The backlight module 120 also includes a lamp bar and an optical film layer, etc., which are not limited by the present invention. In this embodiment, the optical film layer is, for example, a combination of a reflective layer, a diffusion layer, or the light guide layer 121, which is not limited by the present invention.

[0064] Figure 2 This is a cross-sectional schematic diagram of a display device according to an embodiment of the present invention. Figure 3 yes Figure 2 This is a disassembled diagram of some components of the display device. Please refer to it. Figure 2 and Figure 3 In this embodiment, the light guide layer 121 has an incident light side A1, a bottom side A2, and an exit light side A3. The incident light side A1 is adjacent to the bottom side A2, and the bottom side A2 is opposite to the exit light side A3. The display panel 110 corresponds to the exit light side A3.

[0065] In this embodiment, the bracket 122 carries the light guide layer 121 and includes a first segment 1221 corresponding to the light incident side A1, a second segment 1222 corresponding to the bottom side A2, and a transition segment 1223 located between the first segment 1221 and the second segment 1222.

[0066] In this embodiment, the frame 130 is located at the periphery of the backlight module 120. The frame 130 has a first part 133, a second part 134 and a third part 135 connected together, and the first part 133, the second part 134 and the third part 135 correspond to the light-incident side A1, the bottom side A2 and the light-exit side A3 of the light guide layer 121, respectively.

[0067] In this embodiment, the first part 133, the second part 134 and the third part 135 of the frame 130 are U-shaped to more completely cover the periphery of the backlight module 120.

[0068] In this embodiment, the frame 130 includes a first inner surface 131 corresponding to the first segment 1221, a second inner surface 132 corresponding to the second segment 1222, and a first inclined surface S1 and a second inclined surface S2 located between the first inner surface 131 and the second inner surface 132. The first inclined surface S1 and the second inclined surface S2 are connected to each other and correspond to the turning segment 1223 of the support 122. In this embodiment, the inclination of the first inclined surface S1 of the frame 130 is greater than the inclination of the second inclined surface S2.

[0069] In this embodiment, the first portion 133 of the frame 130 has a recess 136 near the third portion 135, and the end E1 of the first segment 1221 of the support 122 engages with the recess 136. For example, the end E1 of the first segment 1221 of the support 122 is bent, and the end E11 of the end E1 faces away from the third portion 135. Here, the end E1 abuts against the recess 136 with a relatively smooth bend to improve the smoothness of rotation when used as a fulcrum, but the invention is not limited thereto.

[0070] In other embodiments, the end E1 of the first segment 1221 of the bracket 122 may also be non-bent, as long as the end E1 of the bracket 122 can serve as a fulcrum when assembling the backlight module 120, it falls within the scope of protection of this invention. For example, Figure 4 This is a cross-sectional schematic diagram of a display device according to an embodiment of the present invention. Please refer to it. Figure 4 The display device 100B includes a backlight module 120B. The backlight module 120B includes a bracket 122B. The end E1' of the first segment 1221B of the bracket 122B is straight, and the end E11' of the end E1' faces the third part 135 of the frame 130, but the present invention is not limited thereto.

[0071] Figure 5 yes Figure 2 This is a schematic diagram showing the assembly of the backlight module and frame. Please refer to it. Figure 5 Under the above configuration, the bracket 122 of the backlight module 120 can be used as a fulcrum position against the recess 136 of the frame 130 through the end E1, and the second part 134 of the frame 130 can be used as a support position.

[0072] In this embodiment, when the frame 130 is assembled with the backlight module 120, the design of the first inclined surface S1 of the frame 130 enables the third part 135 to automatically flip inward. That is, when the frame 130 is assembled with the backlight module 120, the third part 135 has an automatic tendency to rotate inward, preventing it from warping and solving the problems of light leakage and dust intrusion. Furthermore, the design of the second inclined surface S2 of the frame 130 can reduce the opening space of the frame 130, allowing the frame 130 to more tightly enclose the backlight module 120, making it usable by display devices of different sizes and increasing flexibility in configuration.

[0073] In this embodiment, the frame 130 is made of plastic. When the frame 130 is assembled into the backlight module 120, the first inclined surface S1 and the second inclined surface S2 of the frame 130 may interfere with the bracket 122 and cause slight deformation, but the present invention is not limited thereto.

[0074] Furthermore, in this embodiment, the first inclined surface S1 and the second inclined surface S2 are designed to extend throughout the entire Y direction. That is, the entire inner side of the frame 130 has the design of the first inclined surface S1 and the second inclined surface S2, which can enhance the inward flipping force. In this way, the frame 130 can have better stability and strength.

[0075] For details, please refer to Figure 3 In this embodiment, the inner surface of the third portion 135 of the frame 130 has an inclined surface S3. The advantage of this design is that it facilitates demolding, but the invention is not limited thereto. Figure 6 This is a schematic diagram of the framework of another embodiment of the present invention. Please refer to it. Figure 6 In this embodiment, the inner surface of the third part 135C of the frame 130C may also have a plane P1, but the present invention is not limited thereto.

[0076] For more details, please refer to [the relevant documentation / reference]. Figure 2In this embodiment, the display device 100 further includes a circuit board 160. The outer surface of the second portion 134 of the frame 130 has positioning portions T1 for aligning the circuit board 160. The number of positioning portions T1 is at least two, which can improve the positioning effect, but this invention is not limited thereto. In one embodiment, the portion of the second portion 134 that contacts the circuit board 160 can be thickened to fine-tune the circuit board 160 to an appropriate position, but this invention is not limited thereto.

[0077] In this embodiment, the positioning part T1 is arranged discontinuously along the Y direction. Figure 7 yes Figure 2 Another cross-sectional view of the display device. Please refer to... Figure 7 The outer surface of the second part 134 has a clearance space (without a positioning part T1) to allow the flexible circuit board 170 to pass through and avoid interference.

[0078] Figure 8A This is a cross-sectional schematic diagram of a display device according to an embodiment of the present invention. Figure 8B yes Figure 8A A partially enlarged schematic diagram of the heat sink. Please refer to... Figure 8A and Figure 8B The display device 100D in this embodiment and Figure 7 The difference between the display device 100 and the display device 100D is that the display device 100D omits the heat sink. Specifically, the display device 100D includes a backlight module 120D, and the support 122D of the backlight module 120D includes a protrusion 1224 for supporting the light guide layer 121 to maintain the height of the light guide layer 121, but the present invention is not limited thereto.

[0079] In summary, in the display device of the present invention, the support of the backlight module includes a transition section. The frame includes a first inclined surface and a second inclined surface corresponding to the transition section. During the assembly of the frame and the backlight module, the interference between the first and second inclined surfaces and the support generates an automatic inward flipping force on the upper part of the display panel, thereby preventing it from tilting up. This solves the problems of light leakage and dust intrusion, giving the frame better stability and strength.

[0080] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Anyone 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.
