Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this disclosure are within the scope of protection of this disclosure.

[0054] Unless the context otherwise requires, throughout the specification and claims, the term "comprise" and its other forms, such as the third-person singular "comprises" and the present participle "comprising," are interpreted as open-ended and encompassing, meaning "including, but not limited to." In the description of the specification, terms such as "one embodiment," "some embodiments," "exemplary embodiments," "example," "specific example," or "some examples," etc., are intended to indicate that a particular feature, structure, material, or characteristic associated with that embodiment or example is included in at least one embodiment or example of this disclosure. The illustrative representations of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics mentioned may be included in any suitable manner in any one or more embodiments or examples.

[0055] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this disclosure, unless otherwise stated, "a plurality of" means two or more.

[0056] In describing some embodiments, the terms "coupled" and "connected," and their derivative expressions, may be used. The term "connected" should be interpreted broadly; for example, a "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection via an intermediate medium. The term "coupled," for example, indicates that two or more components have direct physical or electrical contact. The term "coupled" or "communicatively coupled" may also refer to two or more components that do not have direct contact with each other but still cooperate or interact with each other. The embodiments disclosed herein are not necessarily limited to the content of this document.

[0057] "At least one of A, B and C" has the same meaning as "at least one of A, B or C", both including the following combinations of A, B and C: only A, only B, only C, combinations of A and B, combinations of A and C, combinations of B and C, and combinations of A, B and C.

[0058] "A and / or B" includes the following three combinations: A only, B only, and a combination of A and B.

[0059] The use of “applies to” or “configured to” in this article implies an open and inclusive language that does not preclude applicability to or configuration to devices that perform additional tasks or steps.

[0060] In addition, the use of “based on” implies openness and inclusivity, because processes, steps, calculations or other actions “based on” one or more of the stated conditions or values ​​may in practice be based on additional conditions or values ​​beyond those stated.

[0061] As used herein, “about,” “approximately,” or “approximately” includes the stated value and the average value within an acceptable range of deviation from the given value, wherein the acceptable range of deviation is determined by a person skilled in the art taking into account the measurement under discussion and the error associated with the measurement of the given quantity (i.e., the limitations of the measurement system).

[0062] As used herein, “parallel,” “perpendicular,” and “equal” include the described situation and situations that are similar to the described situation, within an acceptable range of deviation, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “parallel” includes absolute parallelism and approximate parallelism, where an acceptable range of deviation for approximate parallelism may be, for example, within 5°; “perpendicular” includes absolute perpendicularity and approximate perpendicularity, where an acceptable range of deviation for approximate perpendicularity may also be, for example, within 5°; “equal” includes absolute equality and approximate equality, where an acceptable range of deviation for approximate equality may be, for example, a difference between the two equals being less than or equal to 5% of either one.

[0063] It should be understood that when a layer or element is referred to as being on another layer or substrate, it can mean that the layer or element is directly on the other layer or substrate, or that there is an intermediate layer between the layer or element and the other layer or substrate.

[0064] This document describes exemplary embodiments with reference to cross-sectional views and / or plan views, which are idealized exemplary drawings. In the drawings, the thickness of layers and the area of ​​regions are enlarged for clarity. Therefore, variations in shape relative to the drawings are contemplated due to, for example, manufacturing techniques and / or tolerances. Thus, exemplary embodiments should not be construed as limited to the shapes of the regions shown herein, but rather include shape deviations due to, for example, manufacturing processes. For example, etched areas shown as rectangular would typically have curved features. Therefore, the regions shown in the drawings are schematic in nature, and their shapes are not intended to show the actual shapes of areas of the device, nor are they intended to limit the scope of the exemplary embodiments.

[0065] As shown in FIG1, some embodiments of the present disclosure provide a display device 2000, which can be any device that displays either moving (e.g., video) or fixed (e.g., still image) and either text or images.

[0066] For example, the display device 2000 can be any product or component with display function, such as a television, laptop computer, tablet computer, mobile phone, personal digital assistant (PDA), navigator, wearable device, augmented reality (AR) device, virtual reality (VR) device, in-vehicle display, or flight display.

[0067] In some embodiments, as shown in FIG2, the display device 2000 is a liquid crystal display device. In this case, the display device 2000 includes a display module 1000, which includes a display panel 100, a back plate 200, a middle frame 300, a backlight 400, and a diffuser plate 500.

[0068] As shown in Figure 2, the display panel 100 includes a light-emitting side 100A and a light-receiving side 100B. The light-emitting side 100A refers to the side of the display panel 100 that can emit light (the upper side of the display panel 100 in Figure 2), and the light-receiving side 100B refers to the other side opposite to the light-emitting side 100A (the lower side of the display panel 100 in Figure 2).

[0069] In some examples, as shown in Figure 2, the display panel 100 has a display area AA and a peripheral area BB surrounding the display area AA. The peripheral area BB is an area where no image is displayed, and the peripheral area BB is configured to house display driving circuitry, such as scan driving circuitry and source driving circuitry.

[0070] As shown in Figure 2, the back plate 200 is located on the light-incident side 100B of the display panel 100, and the back plate 200 includes a base plate 210 and side plates 220 surrounding the base plate 210.

[0071] In some examples, the backplate 200 is made of electro-galvanized steel sheet (SECC), hot-dip galvanized steel sheet (SGCC), etc.

[0072] As shown in Figure 2, the middle frame 300 includes a first part 310, a second part 320 and a third part 330.

[0073] The first part 310 is located at the end of the middle frame 300 near the base plate 210, and the plane of the first part 310 intersects with the base plate 210. The third part 330 is located at the end of the middle frame 300 near the display panel 100, and the plane of the third part 330 intersects with the extended surface of the base plate 210. The third part 330 is used to support the display panel 100. The second part 320 connects the first part 310 and the third part 330. The orthographic projection of the second part 320 on the display panel 100 covers the orthographic projection of the side plate 220 on the display panel 100. The plane of the second part 320 is parallel to the base plate 210.

[0074] As shown in Figure 2, the backlight 400 is located on the side of the base plate 210 close to the display panel 100, and on the side of the first part 310 away from the side plate 220.

[0075] In some examples, as shown in Figures 3A, 3B, and 3C, the backlight 400 includes a circuit board 410 and multiple light sources 420. The multiple light sources 420 are connected to the circuit board 410. For example, the light sources 420 are LED chips.

[0076] Based on this, as shown in Figures 3A, 3B, and 3C, multiple light sources 420 are arranged in multiple rows and columns. Each row includes at least two light sources 420 arranged along a third direction M3, and each column includes at least two light sources 420 arranged along a fourth direction. The third direction M3 and the fourth direction M4 intersect, for example, the third direction M3 and the fourth direction M4 are perpendicular.

[0077] For example, as shown in FIG3A, the backlight 400 includes multiple circuit boards 410, and a row of light sources 420 is connected to one circuit board 410. Alternatively, as shown in FIG3B, the backlight 400 includes multiple circuit boards 410, and a row of light sources 420 is connected to one circuit board 410. Alternatively, as shown in FIG3C, the backlight 400 includes one circuit board 410, and multiple light sources 420 (all light sources 420) are connected to the circuit board 410.

[0078] As shown in Figure 2, the diffuser plate 500 is located between the second part 320 and the display panel 100. The diffuser plate 500 is mainly used to mix the light L emitted by the backlight 400, so that the light L enters the display panel 100 evenly, thereby improving the brightness uniformity of the display panel 100.

[0079] As shown in Figure 1, multiple display devices 2000 can be spliced ​​together to form a large display screen 10000. The spliced ​​display screen 10000 can be used in conference rooms, monitoring rooms, command centers, exhibition halls and other occasions that require a large screen display.

[0080] In some embodiments, as shown in FIG2, the display module 1000 further includes a first light-transmitting component 600, which is located between the second part 320 and the diffuser plate 500, and is used to support the diffuser plate 500. The light transmittance of the first light-transmitting component 600 is greater than that of the middle frame 300.

[0081] With this configuration, on the one hand, the first light-transmitting component 600 is used to support the diffuser plate 500, which can reduce the risk of the diffuser plate 500 detaching from the display panel 100 and colliding with the middle frame 300, thus improving the service life of the diffuser plate 500 and the service life of the display device 2000.

[0082] On the other hand, the light transmittance of the first light-transmitting component 600 is greater than that of the middle frame 300, that is, the light transmittance of the first light-transmitting component 600 is larger. The light L emitted by the backlight 400 can pass through the first light-transmitting component 600 and reach the edge of the diffuser plate 500 supported by the middle frame 300. This can increase the amount of light entering the edge area of ​​the diffuser plate 500, reduce the risk of partial darkening of the corresponding edge area of ​​the display device 2000, and help improve the edge image quality and enhance the edge light effect, thereby improving the display effect of the display device 2000.

[0083] In some examples, the light transmittance of the first light-transmitting component 600 is greater than or equal to 90%.

[0084] For example, the light transmittance of the first light-transmitting component 600 is 90%, 91%, 91.4%, 92.6%, 93%, 95%, 97%, 98%, or 99%.

[0085] In some examples, the material of the first light-transmitting component 600 includes polycarbonate (PC), which allows the transmittance of the first light-transmitting component 600 to be greater than or equal to 90%, which is beneficial to improving the uniformity of the display device 2000.

[0086] Furthermore, since the first light-transmitting component 600 made of polycarbonate is a different medium layer from air, as shown in Figure 2, light L in the direction perpendicular to the side plate 220 will undergo total internal reflection in the first light-transmitting component 600. The light L entering the first light-transmitting component 600 will be further utilized, which can further improve the edge brightness of the display device 2000.

[0087] In some embodiments, as shown in FIG2, along the first direction M1, the diffuser plate 500 is located on the side of the third portion 330 close to the first portion 310, and there is a gap between the diffuser plate 500 and the third portion 330. The first direction M1 is parallel to the bottom plate 210 and perpendicular to the side plate 220.

[0088] In this configuration, the gap between the diffuser plate 500 and the third part 330 provides space for the expansion of the diffuser plate 500, which can reduce the risk of the diffuser plate 500 or the third part 330 being damaged due to mutual compression after the diffuser plate 500 expands, thus improving the service life of the display device 2000.

[0089] In some examples, the gap between the diffuser plate 500 and the third part 330 is greater than or equal to 1.5 mm.

[0090] For example, the gap between the diffuser plate 500 and the third part 330 is 1.5mm, 1.54mm, 1.6mm, 1.73mm, 1.8mm, 1.87mm, 2mm, 2.3mm, 2.6mm, 3mm, 4.4mm, 4.7mm or 5mm.

[0091] In some embodiments, as shown in FIG2, along the first direction M1, the width of the portion of the diffuser plate 500 that abuts against the first light-transmitting component 600 is greater than or equal to the gap between the diffuser plate 500 and the third portion 330.

[0092] This configuration reduces the risk of the diffuser plate 500 falling off the first light-transmitting component 600 due to shrinkage, thus improving the service life of the diffuser plate 500.

[0093] In some examples, along the first direction M1, the width of the portion of the diffuser 500 that abuts against the first light-transmitting component 600 is equal to the gap between the diffuser 500 and the third portion 330.

[0094] In some embodiments, the haze of the first light-transmitting component 600 is less than the haze of the diffuser plate 500.

[0095] With this configuration, the haze of the first light-transmitting component 600 is relatively small. As a result, the first light-transmitting component 600 reflects less light and more light enters the first light-transmitting component 600. This increases the amount of light entering the edge area of ​​the diffuser plate 500, reduces the risk of partial darkening of the corresponding edge area of ​​the display device 2000, and helps to improve the display effect of the display device 2000.

[0096] In some embodiments, as shown in FIG4, the haze of the first light-transmitting component 600 is 30% to 50%.

[0097] In this configuration, the point or line light source emitted from the first light-transmitting component 600 can be transformed into a surface light source. The overall image of the display device will be softer and more uniform, without bright edges or dark bands. While ensuring good edge image quality, the edge brightness can be appropriately reduced to improve the uniformity of the surrounding image. This not only meets the requirements for edge image quality but also improves the uniformity of the surrounding image quality.

[0098] For example, the haze of the first light-transmitting component 600 is 30%, 32%, 35%, 39%, 43%, 45%, or 50%.

[0099] In some embodiments, as shown in FIG4, the display module 1000 further includes a diffusing agent (the diffusing agent is generally a micron-sized chemical particle, which can be represented as countless solid microspheres at a microscopic angle. The solid microspheres continuously refract, scatter, and reflect the light L, thereby achieving the effect of light mixing), and the diffusing agent is embedded in the first light-transmitting component 600. In this way, the first light-transmitting component 600 can have a haze.

[0100] In some examples, the dispersant includes inorganic dispersants. For example, the dispersant includes nano-barium sulfate or silica.

[0101] In some embodiments, different haze levels (e.g., 10%, 30%, 50%, 65%) are simulated for the first light-transmitting component 600.

[0102] The simulation results of the first light-transmitting component 600 with a haze of 10% are shown in Figure 5A. Figure 5A is a simulated display screen, a partial schematic diagram of the entire display screen, including the edge represented by 0mm. As shown in Figure 5A, the relative brightness value at a position 5mm from the edge is higher than the relative brightness values ​​at its adjacent two sides, resulting in a bright line on the screen, i.e., a bright edge in the simulated image. The uniformity optimization effect is limited and does not achieve the desired technical effect, therefore it is not considered.

[0103] It should be noted that, based on actual product experience and client standards, edge brightness at a position of 5mm is generally used as the criterion for judging edge image quality.

[0104] Figures 5B and 5C show the simulation results of the first light-transmitting component 600 with a haze of 30%. Curve 1006 in Figure 5B is the simulated brightness curve, and Figure 5C shows the simulated display based on brightness curve 1006 in Figure 5B. Figure 5C is a partial schematic diagram taken from the entire display screen. As shown in Figures 5B and 5C, the brightness curve at 5mm from the screen edge is above 90%, and the uniformity of the simulated visual image is good.

[0105] Figures 5B and 5D show the simulation results of the first light-transmitting component 600 with a haze of 50%. Curve 1005 in Figure 5B is the simulated brightness curve, and Figure 5D shows the simulated display based on brightness curve 1005 in Figure 5B. Figure 5D is a partial schematic diagram cropped from the entire display screen. As shown in Figures 5B and 5D, the brightness curve at the 5mm edge of the screen is above 90%, and the uniformity of the simulated visual image is good.

[0106] The simulation results of the first light-transmitting component 600 with a haze of 60% are shown in Figure 5E. Figure 5E is the simulated display screen, and it is a partial schematic diagram of the entire display screen. As shown in Figure 5E, the brightness curve at the edge of the screen (5mm) is below 85%, and the edge of the simulated screen is noticeably dark, failing to achieve the desired technical effect and therefore not considered.

[0107] The simulation results above demonstrate that when the haze of the first light-transmitting component 600 is between 30% and 50%, the edge brightness curve is above 90%, and the uniformity of the simulated visual image is good.

[0108] In some embodiments, as shown in FIG2, the display module 1000 further includes a first adhesive layer 700, which is located between the first light-transmitting component 600 and the diffuser plate 500, and is bonded to the first light-transmitting component 600 and the diffuser plate 500.

[0109] This configuration allows the first light-transmitting component 600 and the diffuser plate 500 to be fixed, which helps improve the connection stability of the diffuser plate 500 and can mitigate the problem of uneven image quality caused by the offset of the diffuser plate 500.

[0110] In some examples, the first adhesive layer 700 may be double-sided tape, but it is not limited to this.

[0111] In some embodiments, the ratio of the total length (inch) of the first light-transmitting component 600 along the circumference of the middle frame 300 to the weight (kg) of the diffuser plate 500 is 0.16 to 0.26.

[0112] With this configuration, the total length of the first light-transmitting component 600 along the circumference of the middle frame 300 is relatively long, meaning the total length of the first adhesive layer 700 along the circumference of the middle frame 300 is also relatively long. In this way, the first adhesive layer 700 can provide sufficient adhesive force to fix the diffuser plate 500, making the diffuser plate 500 more firmly bonded, further improving the connection stability of the diffuser plate 500, and further improving the problem of uneven image quality around the diffuser plate 500 caused by its offset.

[0113] In some examples, the ratio of the total length (inches) of the first light-transmitting component 600 along the circumference of the middle frame 300 to the weight (kg) of the diffuser plate 500 can be calculated using the adhesive force formula. A mathematical model is established for the fixed area of ​​the diffuser plate 500. The limit value for the fixed area is defined as the ability of the diffuser plate 500 to remain in place without falling due to its own weight.

[0114] From the formula for adhesive force F=k×D×R≥S N ×G, we get: D≥(S) N ×G) / (k×R).

[0115] Where G is the weight of the diffuser plate 500, D is the total length of the first light-transmitting component 600 in the circumferential direction of the first part 310, R is the adhesion coefficient, and S is the total length of the first light-transmitting component 600. N For safety factor, k is the viscosity of the first adhesive layer.

[0116] For example, the first adhesive layer 700 uses a solid pressure-sensitive adhesive. The first adhesive layer 700 has different adhesion coefficients for substrates with different roughnesses. The adhesion capabilities of the first adhesive layer 700 are shown in Table 1. Generally, the roughness R... a 0.4~R a 1.6 is for finely processed, smooth bonding surfaces. Excessive smoothness or roughness will reduce bonding strength. The PC material frame has a smooth surface, and the roughness R of the double-sided adhesive is... 胶 =1, the roughness of the diffuser plate 500 is relatively high, R 扩 =0.5~0.6.

[0117] Table 1

[0118] In the above formula, S N The safety factor reflects the degree of safety in structural design and represents the feasibility of a theoretical model in actual production. In general engineering structural applications, S... N Between 1.5 and 2.0.

[0119] In some embodiments, the diffuser plate 500 weighs 1.5 kg, and the viscosity of the first adhesive layer 700 is k = 15 N / inch. The total length of the first light-transmitting component 600 along the circumference of the middle frame 300 is greater than or equal to 97.5 mm.

[0120] With this configuration, the total length of the first light-transmitting component 600 along the circumference of the middle frame 300 is relatively long, that is, the total length of the first adhesive layer 700 along the circumference of the middle frame 300 is relatively long. In this way, the first adhesive layer 700 can provide sufficient adhesive force to fix the diffuser plate 500, so that the diffuser plate 500 is bonded more firmly.

[0121] For example, the total length of the first light-transmitting component 600 along the circumference of the middle frame 300 is 97.5mm, 99mm, 101mm, 110mm, 115mm, 119mm, 120, 124mm, or 130mm.

[0122] In some embodiments, as shown in Figures 6A, 6B, 6C and 6D, the second part 320 includes a plurality of support bars 321 connected in sequence, with adjacent support bars 321 intersecting, and each support bar 321 having a first light-transmitting component 600 on the side away from the base plate 210.

[0123] With this setup, each edge of the diffuser plate 500 is glued and fixed, which makes the diffuser plate 500 more firmly attached, thereby further improving the problem of uneven image quality around the diffuser plate 500 caused by its offset.

[0124] In some examples, as shown in Figures 6A and 6B, a first light-transmitting component 600 is provided on the side of the support strip 321 away from the base plate 210, and the first light-transmitting component 600 extends along the extension direction of the support strip 321.

[0125] This setup reduces the difficulty of installing the first light-transmitting component 600.

[0126] For example, as shown in FIG6A, the second part 320 includes four support strips 321 connected in sequence. Two of the four support strips 321 are longer and of equal length, while the other two support strips 321 are shorter and of equal length. Under the premise of satisfying the fixing requirements of the diffuser plate 500, the first light-transmitting component 600 and the diffuser plate 500 adopt the shortest total bonding length, that is, the first light-transmitting component 600 adopts the shortest total length. For example, the total length D of the first light-transmitting component 600 is 100mm. For example, the length L1 of the first light-transmitting component 600 on the side of the longer support strip 321 away from the base plate 210 is 30mm, and the length L2 of the first light-transmitting component 600 on the side of the shorter support strip 321 away from the base plate 210 is 20mm.

[0127] In other examples, as shown in Figures 6C and 6D, a plurality of first light-transmitting components 600 are provided on the side of a support strip 321 away from the base plate 210, and the plurality of first light-transmitting components 600 are arranged at intervals along the direction of extension of the support strip 321.

[0128] Setting it up in this way can reduce the amount of materials used and lower costs.

[0129] For example, the width of the plurality of first light-transmitting components 600 disposed on the side of a support strip 321 away from the base plate 210 is the same, and the distance between any two adjacent first light-transmitting components 600 is equal.

[0130] This setup reduces mold-making costs and prevents discrepancies in the final image.

[0131] For example, as shown in FIG6C, the second part 320 includes four support bars 321 connected in sequence. Two of the four support bars 321 are longer and of equal length, while the other two support bars 321 are shorter and of equal length. Six first light-transmitting components 600 are provided on the side of the longer support bars 321 away from the base plate 210, and four first light-transmitting components 600 are provided on the side of the shorter support bars 321 away from the base plate 210.

[0132] It should be noted that Figures 6A and 6C only show the first light-transmitting component 600 on the side of the longer support strip 321 away from the base plate 210, and the first light-transmitting component 600 on the side of the shorter support strip 321 away from the base plate 210. Although the sides of the other longer support strip 321 and the other shorter support strip 321 away from the base plate 210 are not shown, it should be understood that the first light-transmitting component 600 is provided on them.

[0133] The first light-transmitting component 600 can have various specific structural forms. The following describes two structural forms in the embodiments of this disclosure:

[0134] The first structural form: As shown in Figure 7, the first light-transmitting component 600 includes a first surface 610 and a first inclined surface 620 connected to each other. The first surface 610 is the surface of the first light-transmitting component 600 close to the second part 320, and the first inclined surface 620 is the surface of the first light-transmitting component 600 away from the third part 330. The first surface 610 includes a first end 611 connected to the first inclined surface 620.

[0135] The middle frame 300 includes a second surface 322 and a second inclined surface 311 connected to each other. The second surface 322 is the surface of the second portion 320 close to the first light-transmitting component 600, and the second inclined surface 311 is the surface of the first portion 310 away from the third portion 330. The second surface 322 includes a second end 3221 connected to the second inclined surface 311. The first end 311 is located on the side of the second end 3221 away from the third portion 330.

[0136] With this configuration, the first surface 610 extends beyond the second surface 322. A portion of the light L emitted by the backlight 400 can pass through the portion of the first surface 610 that extends beyond the second surface 322 and enter the first light-transmitting component 600. This increases the amount of light entering the edge area of ​​the diffuser plate 500, reduces the risk of the corresponding edge area of ​​the display device 2000 becoming dark, and helps improve the display effect of the display device 2000.

[0137] In some examples, the distance between the orthographic projection of the first end 611 on the display panel 100 and the orthographic projection of the second end 3221 on the display panel 100 is a first distance d1, which is 0mm to 3mm.

[0138] For example, the first distance d1 is 0mm, 0.5mm, 0.8mm, 1mm, 1.2mm, 1.6mm, 2mm, 2.2mm, 2.7mm or 3mm.

[0139] In other examples, the first distance d1 is 1.2 mm to 1.8 mm.

[0140] For example, the first distance d1 is 1.2mm, 1.5mm, 1.7mm or 1.8mm.

[0141] In some other examples, the first distance d1 is 1.5mm to 4.5mm.

[0142] For example, the first distance d1 is 1.5mm, 1.7mm, 2mm, 2.2mm, 2.5mm, 2.8mm, 3mm, 3.3mm, 3.6mm, 3.9mm, 4.2mm or 4.5mm.

[0143] In some other examples, the first distance d1 is 3mm to 6mm.

[0144] For example, the first distance d1 is 3mm, 3.2mm, 3.3mm, 3.5mm, 3.9mm, 4mm, 4.4mm, 4.7mm, 5mm, 5.5mm, 5.8mm or 6mm.

[0145] In some embodiments, as shown in FIG7, the acute angle between the first inclined surface 620 and the base plate 210 is less than or equal to the acute angle between the second inclined surface 311 and the base plate 210.

[0146] This configuration allows for a smaller acute angle between the first inclined surface 620 and the base plate 210, i.e., a smaller angle between the first inclined surface 620 and the first surface 610. This can further increase the amount of light refracted and / or reflected by the first inclined surface 620 to the edge region of the diffuser plate 500, further reducing the risk of partial darkening of the corresponding edge region of the display device 2000, and thus improving the display effect of the display device 2000.

[0147] In some examples, the angle between the second inclined plane 311 and the base plate 210 is greater than or equal to 80° to 85°.

[0148] With this configuration, the angle between the second inclined surface 311 and the base plate 210 is larger, the overlap between the middle frame 300 and the display area AA is smaller, the first part 310 blocks less light L, and more light L can enter the edge of the diffuser plate 500 through the first light-transmitting component 600, which can further increase the amount of light entering the edge area of ​​the diffuser plate 500 and further improve the display effect of the display device 2000.

[0149] For example, the included angle between the second inclined surface 311 and the base plate 210 is 80°, 81°, 82°, 83°, 84° or 85°.

[0150] In some embodiments, as shown in FIG7, the included angle θ between the first inclined surface 620 and the first surface 610 is 56° to 72°.

[0151] For example, the included angle θ between the first inclined plane 620 and the first surface 610 is 56°, 58°, 59°, 60°, 63°, 64°, 67°, 70°, 71° or 72°.

[0152] With this configuration, the angle between the first inclined surface 620 and the first surface 610 is smaller, which can further increase the amount of light refracted and / or reflected by the first inclined surface 620 to the edge area of ​​the diffuser plate 500, further reducing the risk of partial darkening of the corresponding edge area of ​​the display device 2000, and thus improving the display effect of the display device 2000.

[0153] In some embodiments, as shown in FIG7, the surface of the first light-transmitting component 600 away from the second portion 320 is a third surface 630, and the width of the third surface 630 along the first direction M1 is a second distance d2. The first direction M1 is parallel to the base plate 210 and perpendicular to the side plate 220.

[0154] In some examples, the ratio of the first distance d1 to the second distance d2 is 0 to 1.

[0155] For example, the ratio of the first distance d1 to the second distance d2 is 0, 0.2, 0.3, 0.5, 0.6, 0.7, 0.8, 0.9 or 1.

[0156] In other examples, the ratio of the first distance d1 to the second distance d2 is 0.3 to 0.7.

[0157] For example, the first distance d1 is 0.3, 0.4, 0.5, 0.6 or 0.7.

[0158] In some other examples, the ratio of the first distance d1 to the second distance d2 is 0.5 to 1.5.

[0159] For example, the ratio of the first distance d1 to the second distance d2 is 0.5, 0.7, 0.8, 1, 1.2, 1.4 or 1.5.

[0160] In some other examples, the ratio of the first distance d1 to the second distance d2 is 1 to 2.

[0161] For example, the ratio of the first distance d1 to the second distance d2 is 1, 1.1, 1.2, 1.4, 1.5, 1.7, 1.8, 1.9, or 2.

[0162] In some embodiments, as shown in FIG7, the surface of the first light-transmitting component 600 away from the second portion 320 is the third surface 630, and the distance between the first surface 610 and the third surface 630 along the direction perpendicular to the base plate 210 is the third distance d3, that is, the height of the first light-transmitting component 600 is d3.

[0163] In some examples, the ratio between the third distance d3 and the second distance d2 is greater than or equal to 1.5.

[0164] By setting it in this way, the third distance d3 can be made larger, that is, the first light-transmitting component 600 is higher. This can increase the amount of light entering the first light-transmitting component 600, thereby increasing the amount of light entering the edge area of ​​the diffuser plate 500, which is beneficial to improving the display effect of the display device 2000.

[0165] For example, the ratio between the third distance d3 and the second distance d2 is 1.5, 1.7, 2, 2.2, 2.6, 3, 3.3, 3.5, or 4.

[0166] In other examples, the ratio between the third distance d3 and the second distance d2 is less than or equal to 2.

[0167] By setting it in this way, the third distance d3 will not be too large, that is, the height of the first light-transmitting component 600 will not be too high. In this way, the straightness of the surface of the first light-transmitting component 600 near the third part 330 will be smaller, which is beneficial to improving the structural strength of the first light-transmitting component 600.

[0168] For example, the ratio between the third distance d3 and the second distance d2 is 0.8, 1, 1.1, 1.3, 1.5, 1.7, 1.8, 1.9 or 2.

[0169] Taking into account both the structural strength and light intake of the first light-transmitting component 600, the ratio between the third distance d3 and the second distance d2 is 1.5 to 2.

[0170] Straightness refers to the straightness within a given surface: the tolerance zone is the area between two parallel straight lines with a distance of tolerance value t.

[0171] In some embodiments, as shown in FIG7, the third distance d3 is less than or equal to 7 mm.

[0172] For example, the third distance d3 is 1mm, 2mm, 3mm, 4mm, 5mm, 6mm or 7mm.

[0173] In some other embodiments, as shown in FIG8A, the plurality of light sources 420 includes a first light source 4201, which is the light source 420 closest to the middle frame 300 among the plurality of light sources 420. The minimum distance between the orthographic projection of the light-emitting center of the first light source 4201 on the display panel 100 and the orthographic projection of the third surface 630 on the display panel 100 is x1.

[0174] Wherein, d3 and x1 satisfy the formula: d3=a×x1, where a is 0.09~0.2.

[0175] For example, a can be 0.09, 0.1, 0.12, 0.14, 0.15, 0.18, or 0.2.

[0176] This configuration ensures that the luminous flux of the first light source 4201 into the first light-transmitting component 600 remains constant, which is beneficial to improving the display effect of the display device 2000.

[0177] In some examples, x1 is 30mm to 50mm.

[0178] For example, x1 can be 30mm, 32mm, 33mm, 35mm, 36mm, 38mm, 40mm, 42mm, 43mm, 44mm, 45mm, 48mm or 50mm.

[0179] In some examples, d3 is 4.5mm to 6mm.

[0180] For example, x1 can be 4.5mm, 4.8mm, 5.1mm, 5.2mm, 5.6mm, 5.7mm, 5.9mm, or 6mm.

[0181] In some embodiments, as shown in FIG8A, the distance between the light-emitting center of the first light source 4201 and the third surface 630 is a fourth distance d4. The angle between the first inclined surface 620 and the first surface 610 is θ. The relationship between x1, θ and d4 is: tanθ>d4 / x1;

[0182] In this configuration, the light emitted from the light-emitting center of the first light source 4201 into the first light-transmitting component 600 from the first surface 610 will not hit the first inclined surface 620, and thus will not be absorbed, scattered, or refracted by the first inclined surface 620. This reduces the loss of light emitted from the light-emitting center of the first light source 4201 into the first light-transmitting component 600 from the first surface 610, increases the amount of light entering the edge area of ​​the diffuser plate 500, and helps to improve the display effect of the display device 2000.

[0183] In some examples, θ is 56° to 72° and d4 is 32 mm.

[0184] In some embodiments, as shown in FIG8A, the distance between two adjacent light sources 420 along the first direction M1 is x3. The relationship between x1 and x3 is: x3 / 2≥x1;

[0185] With this configuration, the distance between the light-emitting center of the first light source 4201 and the first surface 610 is shorter, which can increase the amount of light emitted from the light-emitting center of the first light source 4201 into the first light-transmitting component 600 from the first surface 610, and increase the amount of light entering the edge area of ​​the diffuser plate 500, which is beneficial to improving the display effect of the display device 2000.

[0186] In some examples, x3 is 60mm to 90mm. For example, x3 is 60mm, 63mm, 65mm, 68mm, 70mm, 74mm, 78mm, 80mm, 83mm, 85mm, 88mm or 90mm.

[0187] In some embodiments, as shown in FIG8B, the minimum distance between the orthographic projection of the light-emitting center of the first light source 4201 on the display panel 100 and the orthographic projection of the first surface 610 on the display panel 100 is x2.

[0188] Where d1 and x2 satisfy the formula: d1=b×x2, where b is 0~0.03;

[0189] For example, b can be 0, 0.01, 0.02, or 0.03.

[0190] This configuration ensures a constant amount of light entering the first light-transmitting component 600 from the portion of the first surface 610 extending beyond the second surface 322, which is beneficial for improving the display effect of the display device 2000.

[0191] In some examples, x2 is 30mm to 50mm.

[0192] For example, x2 can be 30mm, 32mm, 33mm, 35mm, 36mm, 38mm, 40mm, 42mm, 43mm, 44mm, 45mm, 48mm, or 50mm.

[0193] In some examples, d1 is 0mm to 1.5mm.

[0194] For example, d1 can be 0mm, 0.2mm, 0.3mm, 0.5mm, 0.6mm, 0.7mm, 0.8mm, 1.0mm, 1.2mm, 1.3mm, 1.4mm, or 1.5mm.

[0195] In some embodiments, as shown in FIG8B, the relationship between d1 and x2 is: d1 and x2 2 Inversely proportional.

[0196] With this configuration, the larger the first distance d1, the smaller the minimum distance between the orthographic projection of the light-emitting center of the first light source 4201 onto the display panel 100 and the orthographic projection of the first surface 610 onto the display panel 100. This means the first light source 4201 is closer to the first sub-part 310. Consequently, more light from the first light source 4201 enters the first light-transmitting component 600 from the first surface 610. However, most of this light will be absorbed by the first inclined surface 620. In other words, most of the light from the first light source 4201 entering the first light-transmitting component 600 from the first surface 610 is absorbed by the first inclined surface 620, with only a small portion reaching the edge region of the diffuser plate 500.

[0197] The smaller the first distance d1, the greater the minimum distance between the orthographic projection of the light-emitting center of the first light source 4201 on the display panel 100 and the orthographic projection of the first surface 610 on the display panel 100. That is, the more the first light source 4201 is away from the first sub-part 310. In this way, less light from the first light source 4201 enters the first light-transmitting component 600 from the first surface 610. However, a small portion of the light from the first light source 4201 entering the first light-transmitting component 600 from the first surface 610 will hit the first inclined surface 620 or will not hit the first inclined surface 620. That is, a small portion of the less light from the first light source 4201 entering the first light-transmitting component 600 from the first surface 610 is absorbed by the first inclined surface 620, and most of the light can enter the edge area of ​​the diffuser plate 500.

[0198] A small portion of the majority of the light rays from the first light source 4201 incident on the first surface 610 into the first light-transmitting component 600 enters the edge region of the diffuser plate 500, while the majority of the relatively small amount of light rays from the first light source 4201 incident on the first surface 610 into the first light-transmitting component 600 enters the edge region of the diffuser plate 500. This ensures a constant amount of light entering the edge region of the diffuser plate 500 from the first light source 4201 incident on the first surface 610, which is beneficial for improving the display effect of the display device 2000.

[0199] In some embodiments, in order to ensure the authenticity and practical applicability of the simulation model parameters, the control group (support and diffuser plate 500 abutting) is first simulated and tested.

[0200] The simulation results are shown in Figures 9A and 9B. In Figure 9A, curve 1001 represents the brightness curve of the control group in the simulation. In Figure 9A, the horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the relative brightness ratio. 1 represents the center brightness of display module 1000 (the specific brightness varies depending on product specifications and is not limited). For example, if the display device 2000 is 55 inches, the center brightness of display module 1000 is 520 nits to 550 nits. Figure 9B shows the simulated display based on the brightness curve 1001 of the control group in Figure 9A. Figure 9B is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 9B represents the distance to the screen edge (0mm represents the screen edge). As shown in Figures 9A and 9B, the control group reaches peak brightness at a distance of 15mm from the edge, and the darker areas are those between 0 and 15mm from the edge.

[0201] The actual test results are shown in Figure 9A, where curve 1002 represents the brightness curve of the control group in the actual test. Comparing curves 1001 and 1002, it can be seen that the simulated results of the control group are basically the same as the measured results. Therefore, it can be proven that the model parameters are highly accurate and practically applicable.

[0202] Based on this, simulation was performed on Experimental Group 1 (display module 1000 includes a first light-transmitting component 600, and the first light-transmitting component 600 has a first surface 610). The simulation results are shown in Figures 9A and 9C. In Figure 9A, curve 1003 is the brightness curve of Experimental Group 1, and Figure 9C shows the simulated display based on brightness curve 1003 in Figure 9A. Figure 9C is a partial schematic diagram cropped from the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 9C represents the distance to the screen edge (0mm represents the screen edge). According to Figures 9A and 9C, the brightness reaches its peak at a distance of 10mm from the edge, and the brightness decay range (darkening area) is 0–10mm.

[0203] According to the brightness curve 1001 in Figure 9A, the brightness at a position 5mm from the edge in the control group is about 90%. According to the brightness curve 1004 in Figure 9A, the brightness at a position 5mm from the edge in the experimental group 1 is about 95%. Therefore, it can be said that the edge image quality of the display device 2000 provided by some embodiments of this disclosure is significantly improved, with good effect, that is, the display image is better and the uniformity is better.

[0204] In some embodiments, as shown in FIG10A, the display module 1000 does not include the first light-transmitting component 600.

[0205] Based on the above structure, simulations were performed, and the results are shown in Figures 10B and 10C. Figure 10B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the light intensity. Figure 10C shows the simulated display based on the curve in Figure 10B. Figure 10C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. According to Figures 10B and 10C, the light intensity at the 0mm position is less than 2E-05 lux (cd), meaning the edge light intensity of the display device 2000 is less than 2E-05cd.

[0206] In some embodiments, different ratios of the first distance d1 to the second distance d2 are simulated.

[0207] In some examples, as shown in Figure 11A, the ratio of the first distance d1 to the second distance d2 is 0, that is, the first distance d1 is 0 mm.

[0208] Based on the above structure, simulations were performed, and the results are shown in Figures 11B and 11C. Figure 11B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the light intensity. Figure 11C shows the simulated display based on the curve in Figure 11B. Figure 11C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 11C represents the distance to the screen edge (0mm represents the screen edge). According to Figures 11B and 11C, the light intensity at the 0mm position is 2E-05cd, meaning the edge light intensity of the display device 2000 is 2E-05cd. At this point, the edge light intensity of the display device 2000 is greater than the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0209] In other examples, as shown in Figure 12A, the ratio of the first distance d1 to the second distance d2 is 0.5.

[0210] Based on the above structure, simulations were performed, and the results are shown in Figures 12B and 12C. Figure 12B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the light intensity. Figure 12C shows the simulated display based on the curve in Figure 12B. Figure 12C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 12C represents the distance to the screen edge (0mm represents the screen edge). According to Figures 12B and 12C, the light intensity at the 0mm position is 4E-05cd, meaning the edge light intensity of the display device 2000 is 4E-05cd. At this point, the edge light intensity of the display device 2000 is greater than the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0211] In other examples, as shown in Figure 13A, the ratio of the first distance d1 to the second distance d2 is 1.

[0212] Based on the above structure, simulations were performed, and the results are shown in Figures 13B and 13C. Figure 13B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the light intensity. Figure 13C shows the simulated display based on the curve in Figure 13B. Figure 13C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 13C represents the distance to the screen edge (0mm represents the screen edge). According to Figures 13B and 13C, the light intensity at the 0mm position is 2E-05cd, meaning the edge light intensity of the display device 2000 is 2E-05cd. At this point, the edge light intensity of the display device 2000 is greater than the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0213] In some other examples, as shown in Figure 14A, the ratio of the first distance d1 to the second distance d2 is 1.5.

[0214] Based on the above structure, simulations were performed, and the results are shown in Figures 14B and 14C. Figure 14B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the light intensity. Figure 14C shows the simulated display based on the curve in Figure 14B. Figure 14C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 14B represents the distance to the screen edge (0mm represents the screen edge). According to Figures 14B and 14C, the light intensity at the 0mm position is less than 2E-05cd, meaning the edge light intensity of the display device 2000 is less than 2E-05cd. Therefore, the edge light intensity of the display device 2000 is less than or equal to the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0215] In some other examples, as shown in Figure 15A, the ratio of the first distance d1 to the second distance d2 is 2.

[0216] Based on the above structure, simulations were performed, and the results are shown in Figures 15B and 15C. Figure 15B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents brightness. Figure 15C shows the simulated display based on the curve in Figure 15B. Figure 15C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 15C represents the distance to the screen edge (0mm represents the screen edge). According to Figures 15B and 15C, the light intensity at the 0mm position is less than 2E-05cd, meaning the edge light intensity of the display device 2000 is less than 2E-05cd. Therefore, the edge light intensity of the display device 2000 is less than or equal to the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0217] As shown in Figures 10A to 15C, when the ratio of the first distance d1 to the second distance d2 is less than or equal to 1, the edge luminous intensity of the display device 2000 is greater than or equal to 2E-05 cd. When the ratio of the first distance d1 to the second distance d2 is greater than 1, the edge luminous intensity of the display device 2000 is less than or equal to the edge luminous intensity of the display module 1000 excluding the first light-transmitting component 600. Therefore, the simulation results above demonstrate that a ratio of 0 to 1 between the first distance d1 and the second distance d2 can increase the edge luminous intensity of the display device 2000, which is beneficial for improving the display effect of the display device 2000.

[0218] As shown in Figures 11A to 13C, when the ratio of the first distance d1 to the second distance d2 is 0.5, the edge light intensity of the display device 2000 is at its maximum. In other words, when the ratio of the first distance d1 to the second distance d2 is around 0.5 (for example, a ratio of 0.3 to 0.7), the edge brightness of the display panel 100 is relatively high, which can result in a greater edge light intensity for the display device 2000, thus improving the display effect of the display device 2000.

[0219] In some embodiments, as shown in Figures 16 and 17, the first light-transmitting component 600 includes a first inclined surface 620 away from the third portion 330 and a first surface 640 near the second portion 220. The first surface 640 includes a fourth surface 641 and a first arc surface 642 connected to each other. The first arc surface 642 includes a first side 6421 connected to the fourth surface 641 and a second side 6422 connected to the first inclined surface 620.

[0220] In some examples, the radius of curvature of the first arc surface 642 is 3 mm to 5 mm.

[0221] By setting it in this way, the area of ​​the light incident surface of the first light-transmitting component 600, i.e. the area of ​​the first inclined surface 620, can be increased, which can increase the amount of light entering the first light-transmitting component 600, further increase the amount of light entering the edge area of ​​the diffuser plate 500, and improve the display effect of the display device 2000.

[0222] For example, the radius of curvature of the first arc surface 642 is 3mm, 3.2mm, 3.5mm, 3.8mm, 4mm, 4.3mm, 4.8mm or 5mm.

[0223] In some examples, the distance between the orthographic projection of the first side 6421 on the display panel 100 and the orthographic projection of the second side 6422 on the display panel 100 is a fifth distance d5, which is 1.5mm to 2.5mm.

[0224] For example, the fifth distance d5 is 1.5mm, 1.6mm, 1.8mm, 2.0mm, 2.3mm or 2.5mm.

[0225] In other examples, the fifth distance d5 is 1.5 mm to 4 mm.

[0226] For example, the fifth distance d5 is 1.5mm, 1.8mm, 2mm, 2.4mm, 2.6mm, 3mm, 3.7mm or 4mm.

[0227] In some other examples, the fifth distance d5 is 2.5 mm to 5 mm.

[0228] For example, the fifth distance d5 is 2.5mm, 2.7mm, 2.8mm, 3mm, 3.1mm, 3.4mm, 3.6mm, 4.3mm, 4.5mm, 4.8mm or 5mm.

[0229] In some other examples, the fifth distance d5 is 4mm to 5mm.

[0230] For example, the fifth distance d5 is 4mm, 4.3mm, 4.6mm, 4.9mm or 5mm.

[0231] In some embodiments, as shown in FIG17, the surface of the first portion 310 away from the third portion 330 includes a second inclined surface 311, and the surface of the second portion 320 near the first light-transmitting component 600 includes a fifth surface 323. The second inclined surface 311 and the fifth surface 323 are connected by a second arc surface 1. The fifth surface 323 is connected to the fourth surface 641, and the second arc surface 1 is connected to the first arc surface 642.

[0232] In this configuration, the second arc surface 1 can scatter the light L incident on the first arc surface 642, thereby making the light L more uniform and reducing the risk of bright lines or dark edges appearing on the display device.

[0233] A simulation experiment was conducted on experimental group 2 (display module 1000 including a first light-transmitting component 600, the first light-transmitting component 600 including a first surface 640). The simulation results are shown in Figures 9A and 18. In Figure 9A, curve 1004 is the simulated brightness curve, and Figure 18 shows the simulated display based on brightness curve 1004 in Figure 9A. Figure 18 is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 9A represents the distance to the screen edge (0mm represents the screen edge). According to Figures 9A and 18, the brightness reaches its peak at a distance of 10mm from the edge, and the brightness decay range (darkening area) is 0–10mm.

[0234] As shown by brightness curve 1001 in Figure 9A, in the control group, the brightness at a position 5mm from the edge is approximately 90%. As shown by brightness curve 1004 in Figure 9A, in experimental group 2, the brightness at a position 5mm from the edge is approximately 95%. Therefore, it can be said that the display device 2000 provided in some embodiments of this disclosure exhibits a significant improvement in edge image quality, resulting in a better display and improved uniformity.

[0235] In some embodiments, the distance d5 between different first sides 6421 and second sides 6422 is simulated.

[0236] In some examples, as shown in Figure 19A, the distance d5 between the first side 6421 and the second side 6422 is 1.5 mm.

[0237] Based on the above structure, simulations were performed, and the results are shown in Figures 19B and 19C. Figure 19B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the light intensity. Figure 19C shows the simulated display based on the curve in Figure 19B. Figure 19C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis of Figure 19C is the distance to the screen edge (0mm represents the screen edge). According to Figures 19B and 19C, the light intensity at the 0mm position is 2E-05cd, meaning the edge light intensity of the display device 2000 is 2E-05cd. At this point, the edge light intensity of the display device 2000 is greater than the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0238] In some examples, as shown in Figure 20A, the distance d5 between the first side 6421 and the second side 6422 is 2.5 mm.

[0239] Based on the above structure, simulations were performed, and the results are shown in Figures 20B and 20C. Figure 20B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents brightness. Figure 20C shows the simulated display based on the curve in Figure 20B. Figure 20C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 20C represents the distance to the screen edge (0mm represents the screen edge). According to Figures 20B and 20C, the light intensity at 0mm is greater than 2E-05cd, meaning the edge light intensity of the display device 2000 is greater than 2E-05cd. Therefore, the edge light intensity of the display device 2000 is greater than the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0240] In some examples, as shown in Figure 21A, the distance d5 between the first side 6421 and the second side 6422 is 4 mm.

[0241] Based on the above structure, simulations were performed, and the results are shown in Figures 21B and 21C. Figure 21B shows the simulated light intensity curve. The horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the light intensity. Figure 21C shows the simulated display based on the curve in Figure 21B. Figure 21C is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. The horizontal axis in Figure 21C represents the distance to the screen edge (0mm represents the screen edge). According to Figures 21B and 21C, the light intensity at the 0mm position is greater than 2E-05cd. That is, the edge light intensity of the display device 2000 is greater than 2E-05cd. Therefore, the edge light intensity of the display device 2000 is greater than the edge light intensity of the display module 1000 excluding the first light-transmitting component 600.

[0242] As shown in Figures 10A-10C and 19A-21C, when the distance d5 between the first side 6421 and the second side 6422 is greater than or equal to 2.5mm, the edge light intensity of the display device 2000 is greater than the edge light intensity of the display module 1000 excluding the first light-transmitting component 600. Therefore, the simulation results above prove that a distance d5 between the first side 6421 and the second side 6422 that is greater than or equal to 2.5mm and less than or equal to 4mm is beneficial to improving the display effect of the display device 2000.

[0243] As shown in Figures 19A to 21C, when the distance d5 between the first side 6421 and the second side 6422 is changed from 1.5mm to 2.5mm, the edge brightness of the display panel 100 increases. When the distance d5 between the first side 6421 and the second side 6422 is changed from 2.5mm to 4mm, the edge brightness of the display panel 100 remains almost unchanged. Therefore, it can be proven that increasing the distance d5 between the first side 6421 and the second side 6422 by 4mm does not change the edge brightness of the display panel 100.

[0244] In summary, the distance d5 between the first side 6421 and the second side 6422 is greater than or equal to 2.5mm, which is beneficial to improving the edge brightness of the display panel 100.

[0245] Based on this, due to the influence of other structures, such as the structure connecting the first light-transmitting component 600 and the first part 310 described below, the maximum width of the orthographic projection of the first arc surface 642 onto the reference plane is 5 mm. Therefore, the distance d5 between the first side 6421 and the second side 6422 is 2.5 mm to 5 mm.

[0246] In some embodiments, as shown in FIG22A, the middle frame 300 further includes a protrusion 340 located on the side of the second portion 320 away from the base plate 210 and on the side of the third portion 330 close to the first portion 310, and the protrusion 340 is connected to the second portion 320 and / or the third portion 330.

[0247] A groove 660 is provided on the surface of the first light-transmitting component 600 near the first part 310. A protrusion 340 is inserted into the groove 660 so that the middle frame 300 and the first light-transmitting component 600 are inserted together. The thick black arrow in Figure 22A indicates the assembly direction of the middle frame 300 and the first light-transmitting component 600.

[0248] In this configuration, the protrusion 340 and the groove 660 cooperate to prevent the first light-transmitting component 600 from sliding relative to the middle frame 300 along the first direction M1.

[0249] As shown in Figure 22A, the surface of the third portion 330 near the first portion 310 includes a second side surface 331, and the surface of the second portion 320 near the first light-transmitting component 600 includes a fifth side surface 323. The second side surface 331 and the fifth side surface 323 are perpendicular, and the fifth side surface 323 is parallel to the base plate 210. The protrusion 340 includes a fourth side surface 341 connected to the second side surface 331 and a sixth side surface 342 connected to the fifth side surface 323. In the first direction M1, the protrusion 340 includes a limiting portion that limits the first light-transmitting component 600.

[0250] In this configuration, the limiting portion of the protrusion 340 cooperates with the second portion 320 and the third portion 330, which can improve the connection stability between the first portion 310 and the first light-transmitting component 600, limit and fix the first light-transmitting component 600 in the first direction M1, and limit and fix the first light-transmitting component 600 by the weight of the diffuser plate 500 in the direction perpendicular to the base plate 210.

[0251] In some examples, as shown in Figures 22A and 22B, the protrusion 340 extends in a direction perpendicular to the base plate 210. The protrusion 340 includes a first connecting portion 343 and a second connecting portion 344. The first connecting portion 343 connects to the second portion 320 and the third portion 330. The second connecting portion 344 is located on the side of the first connecting portion 343 away from the third portion 330 and connects to both the first connecting portion 343 and the second portion 320. Along the second direction M2, the width of the first connecting portion 343 is smaller than the width of the second connecting portion 344. The side of the first connecting portion 343 away from the second connecting portion 344 is a fourth side surface 341, and the second connecting portion 344 serves as a limiting portion. The second direction M2 intersects the first direction M1 and is parallel to the display panel 100; for example, the second direction M2 is perpendicular to the first direction M1.

[0252] It should be noted that the orthographic projection of the protrusion 340 on the display panel 100 can also be other shapes, such as rhombus (as shown in Figure 22C), triangle (as shown in Figure 22D), or cylinder (as shown in Figure 22E), as long as it can cooperate with the second part 320 and the third part 330 of the first part 310 to limit and fix the first light-transmitting component 600 in the first direction M1.

[0253] In some embodiments, as shown in FIG22B, the second part 320 includes a plurality of support bars 321 connected in sequence, and two adjacent support bars 321 intersect each other. Each support bar 321 has a protrusion 340 on the side away from the base plate 210.

[0254] For example, the second part 320 is connected in sequence to four support bars 321.

[0255] In some examples, a protrusion 340 is provided on the side of a support bar 321 away from the base plate 210.

[0256] In other examples, a support strip 321 has multiple protrusions 340 on the side away from the base plate 210, and the multiple protrusions 340 are arranged at intervals along the direction of extension of the support strip 321. The corresponding first light-transmitting component 600 has multiple grooves 660 that mate with the corresponding protrusions 340.

[0257] Based on this, as shown in Figure 22B, the plurality of protrusions 340 include at least one first positioning protrusion 345 for positioning the first light-transmitting component 600, wherein the length of the first positioning protrusion 345 is greater than the length of the other protrusions 340 in the circumferential direction of the middle frame 300.

[0258] In some examples, as shown in Figure 22B, the first positioning protrusion 345 includes a first sub-positioning protrusion 3451 and a second sub-positioning protrusion 3452. In the circumferential direction of the middle frame 300, the length L3 of the first sub-positioning protrusion 3451 is greater than the length L4 of the second sub-positioning protrusion 3452. The first sub-positioning protrusion 3451 is used to achieve fine positioning of the first light-transmitting component 600, and the second sub-positioning protrusion 3452 is used to achieve coarse positioning of the first light-transmitting component 600.

[0259] For example, in the circumferential direction of the middle frame 300, the length L1 of the first sub-positioning protrusion 3451 is 20mm to 30mm, and the length L2 of the second sub-positioning protrusion 3452 is 15mm to 25mm.

[0260] For example, the length L1 of the first sub-positioning protrusion 3451 is 20mm, 21mm, 23mm, 24mm, 27mm, 28mm, 29mm or 30mm.

[0261] For example, the length L2 of the second sub-positioning protrusion 3452 is 15mm, 16mm, 18mm, 19mm, 20mm, 22mm, 23mm, 24mm or 25mm.

[0262] It should be noted that when multiple protrusions 340 are arranged at intervals on the side of a support bar 321 away from the base plate 210, the number of protrusions 340 can be set according to actual needs.

[0263] In some examples, as shown in Figure 22B, the second part 320 includes four support bars 321 connected in sequence. Two of the four support bars 321 are longer and of equal length, while the other two are shorter and of equal length. The longer support bars 321 have five protrusions 340 on the side away from the base plate 210, and the shorter support bars 321 have three protrusions 340 on the side away from the base plate 210.

[0264] In other examples, the second part 320 includes four support bars 321 connected in sequence. Two of the four support bars 321 are longer and of equal length, while the other two are shorter and of equal length. The longer support bars 321 have six protrusions 340 on the side away from the base plate 210, and the shorter support bars 321 have four protrusions 340 on the side away from the base plate 210.

[0265] It should be noted that only the protrusions 340 on one longer support bar 321 and one shorter support bar 321 are shown in Figure 22B. It should be understood that protrusions 340 are also provided on the other longer support bar 321 and the other shorter support bar 321.

[0266] In some embodiments, the longer support bar 321 has six protrusions 340 on the side away from the base plate 210, and the shorter support bar 321 has four protrusions 340 on the side away from the base plate 210. Based on satisfying the support strength of the protrusions 340, the shortest length of the protrusions 340 can be set to 4mm in the circumferential direction of the middle frame 300.

[0267] Based on this, the number of first light-transmitting components 600 and protrusions 340 provided on the side of a support strip 321 away from the base plate 210 is equal. The length of the first light-transmitting component 600 can be set to 7mm. Thus, in the circumferential direction of the middle frame 300, the total length D of the first light-transmitting component 600 is 140mm, which is greater than 97.5mm, satisfying the bonding strength requirement (the total length of the first adhesive layer 700 between the first light-transmitting component 600 and the diffuser plate 500 is the same as the total length of the corresponding first light-transmitting component 600).

[0268] In some embodiments, as shown in FIG22F, a first mounting cavity is formed between the first light-transmitting component 600 and the middle frame 300. The display module 1000 further includes a second adhesive layer 800, which is located in the first mounting cavity and is bonded to the first portion 310 and the first light-transmitting component 600.

[0269] In some examples, the surface of the first light-transmitting component 600 near the second portion 320 has a first opening 670, and a second adhesive layer 800 is located within the first opening 670, bonding the second adhesive layer 800 to the first portion 310 and the first light-transmitting component 600. In this case, the first opening 670 and the surfaces of the second portion 320 away from the base plate 210 form a first mounting cavity.

[0270] In other examples, the surface of the first light-transmitting component 600 near the third portion 330 has a second opening 680, and a second adhesive layer 800 is located within the second opening 680, bonding the second adhesive layer 800 to the first portion 310 and the first light-transmitting component 600. In this case, the second opening 680 and the surface of the third portion 330 near the first portion 310 form a first mounting cavity.

[0271] In some other examples, as shown in Figure 22F, the surface of the first light-transmitting component 600 near the second portion 320 has a first opening 670, and the surface of the first light-transmitting component 600 near the third portion 330 has a second opening 680. The second adhesive layer 800 is partially located within the first opening 670 and partially within the second opening 680, and the second adhesive layer 800 is bonded to the first portion 310 and the first light-transmitting component 600. In this case, the first opening 670, the second opening 680, the surface of the second portion 320 away from the base plate 210, and the surface of the third portion 330 near the first portion 310 form a first mounting cavity.

[0272] In some embodiments, as shown in FIG22G, the surface of the second part 320 away from the base plate 210 is provided with a second receiving groove 324, and the middle frame 300 further includes a second light-transmitting component 900. The second light-transmitting component 900 is located in the second receiving groove 324. The second light-transmitting component 900 is integrally formed with the first light-transmitting component 600. Along the first direction M1, the maximum width of the second light-transmitting component 900 is greater than the width of the opening of the second receiving groove 324.

[0273] In some examples, as shown in FIG22G, the second receiving slot 324 includes a first slot portion 3241 and a second slot portion 3242. The first slot portion 3241 is located on the side of the second slot portion 3242 away from and close to the display panel 100, and along the first direction M1. The width of the first slot portion 3241 is smaller than the width of the second slot portion 3242. The maximum width of the second light-transmitting component 900 in the second slot portion 3242 is greater than the width of the first slot portion 3241.

[0274] In some examples, the middle frame 300, the first light-transmitting component 600, and the second light-transmitting component 900 are formed simultaneously using a two-color injection molding process.

[0275] In some embodiments, as shown in FIG23A, the second portion 320 has a third receiving groove 325 on the surface near the base plate 210, and the third receiving groove 325 surrounds the first portion 310. One end of the side plate 220 away from the base plate 210 is located in the third receiving groove 325, and the surface of the side plate 220 away from the first portion 310 is in contact with the third receiving groove 325.

[0276] This configuration prevents the middle frame 300 from moving relative to the side panel 220 in the first direction M1.

[0277] In some examples, as shown in Figure 23A, the side panel 220 includes a first sub-panel 221, a second sub-panel 222, and a third sub-panel 223. The first sub-panel 221 is connected to the bottom plate 210. The second sub-panel 222 is located on the side of the first sub-panel 221 away from the bottom plate 210, and on the side of the first sub-panel 221 away from the first portion 310. One end of the second sub-panel 222 away from the bottom plate 210 is located within a third receiving groove 325. The third sub-panel 223 is located between the first sub-panel 221 and the second sub-panel 222, and is connected to both the first sub-panel 221 and the second sub-panel 222.

[0278] Based on this, the surface of the second sub-plate 222 away from the first portion 310 is the first side surface 2221, and the surface of the third portion 330 near the first portion 310 includes the second side surface 331. The first side surface 2221 is flush with the second side surface 331 (as shown in Figure 23A), or the first side surface 2221 is located on the side of the second side surface 331 away from the first portion 310.

[0279] By setting it in this way, the distance d6 between the first part 310 and the third part 330 can be reduced, that is, the overlapping part of the first part 3103 with the display area AA can be reduced. This reduces the obstruction of the light L emitted by the backlight 400 by the first part 310, and further increases the amount of light L directly incident from the backlight 400 into the diffuser plate 500, which is beneficial to improving the display effect of the display device 2000.

[0280] In some embodiments, the first side surface 2221 is located on the side of the second side surface 331 away from the first portion 310, and the surface of the second sub-plate 222 near the first portion 310 is the third side surface 2222. The third side surface 2222 is flush with the second side surface 331, or the third side surface 2222 is located on the side of the second side surface 331 away from the first portion 310. Along the first direction M1, the width of the third portion 330 is greater than the width of the first sub-plate 221.

[0281] With this configuration, the distance d6 between the first part 310 and the third part 330 can be further reduced, that is, the overlap between the first part 310 and the display area AA can be further reduced. This reduces the obstruction of the light L emitted by the backlight 400 by the first part 310, and further increases the amount of light L directly incident from the backlight 400 into the diffuser plate 500, which is beneficial to improving the display effect of the display device 2000.

[0282] In some embodiments, as shown in FIG23A, the distance d6 between the first portion 310 and the third portion 330 along the first direction M1 is less than or equal to 5.9mm.

[0283] With this configuration, the distance d6 between the first part 310 and the third part 330 is smaller, which reduces the overlap between the first part 310 and the display area AA. This reduces the obstruction of the light L emitted by the backlight 400 by the first part 310, increases the amount of light L directly incident from the backlight 400 into the diffuser plate 500, and helps improve the display effect of the display device 2000.

[0284] For example, the distance d6 between the first part 310 and the third part 330 is 3.3mm, 3.5mm, 3.7mm, 3.8mm, 4mm, 4.3mm, 4.5mm, 4.7mm, 4.9mm, 5mm, 5.1mm, 5.3mm, 5.5mm, 5.7mm, 5.8mm or 5.9mm.

[0285] In some other embodiments, as shown in FIG23A, the middle frame 300 further includes a protrusion 340, and the distance d6 between the first portion 310 and the third portion 330 is greater than or equal to 4.4mm.

[0286] This configuration prevents the distance d6 between the first part 310 and the third part 330 from being too small, and also prevents the distance between the first sub-part and the protrusion 340 from being too small. The light L emitted by the backlight 400 is located above the protrusion 340 (the side of the protrusion 340 closest to the display panel 100). In this way, the light L emitted by the backlight 400 will not be blocked by the protrusion 340, ensuring that the light L is utilized to the maximum extent, which is beneficial to improving the display effect of the display panel 100.

[0287] For example, the distance d6 between the first part 310 and the third part 330 is 4.4mm, 4.5mm, 4.7mm, 4.9mm, 5mm, 5.1mm, 5.3mm, 5.5mm, 5.7mm, 5.8mm, 5.9mm, 6.2mm, 6.7mm, 7mm, 7.5mm or 8mm.

[0288] Taking all factors into consideration, the distance d6 between the first part 310 and the third part 330 is 4.4mm to 5.9mm.

[0289] In some embodiments, as shown in FIG23A, the height h of the protrusion 340 along the direction perpendicular to the base plate 210 is 3.5mm to 5mm.

[0290] With this configuration, the height of the protrusion 340 is relatively low, and the light L emitted by the backlight 400 is located above the protrusion 340. In this way, the light L emitted by the backlight 400 will not be blocked by the protrusion 340, ensuring that the light L is utilized to the maximum extent, which is beneficial to improving the display effect of the display panel 100.

[0291] For example, the height of the protrusion 340 is 3.5mm, 3.7mm, 4mm, 4.1mm, 4.4mm, 4.6mm, 4.9mm or 5mm.

[0292] In some embodiments, as shown in FIG23B, the middle frame 300 further includes a protrusion 340, and the first side 2221 is located on the side of the second side 331 near the first portion 310. In this case, the distance d6 between the first portion 310 and the third portion 330 is 5.9mm.

[0293] Based on the above structure, simulations were performed, and the results are shown in Figures 23C and 23D. Figure 23C shows the simulated illuminance curve. In Figure 23C, the horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the illuminance. Figure 23D shows the simulated display based on the illuminance curve in Figure 23C. Figure 23D is a partial schematic diagram cropped from the entire display screen, including the edge represented by 0mm. In Figure 23D, the horizontal axis represents the distance to the screen edge (0mm represents the screen edge).

[0294] In some other embodiments, as shown in FIG23A, the middle frame 300 further includes a protrusion 340, the first side 2221 is flush with the second side 331, or the first side 2221 is located on the side of the second side 331 away from the first part 310, in which case the distance d1 between the distance d6 between the first part 310 and the third part 330 is 4.4mm.

[0295] Based on the above structure, simulations were performed, and the simulation results are shown in Figures 23E and 23F. Figure 23E shows the simulated illuminance curve. In Figure 23E, the horizontal axis represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the illuminance. Figure 23F shows the simulated display based on the illuminance curve in Figure 23E. Figure 23F is a partial schematic diagram of the entire display screen, including the edge represented by 0mm. In Figure 23F, the horizontal axis represents the distance to the screen edge (0mm represents the screen edge).

[0296] As shown in Figures 23C to 23F, after shortening the distance d6 between the first part 310 and the third part 330, the illuminance at coordinate 0mm in Figure 23E increases, meaning the brightness at the product edge in Figure 23F increases. The slope of the curve from coordinates 0mm to 5mm in Figure 23E increases significantly, indicating that the brightness increases faster at positions 1 to 3mm from the product edge, resulting in a more noticeable improvement in luminous efficacy.

[0297] In some embodiments, as shown in FIG2, in the orthographic projection onto the display panel 100, the orthographic projection of the surface of the first light-transmitting component 600 away from the third portion 330 onto the display panel 100 is located in the peripheral area BB.

[0298] This configuration ensures sufficient light emission at the edges of the display area AA, further improving the issue of dark edges on the display panel 100.

[0299] In some examples, as shown in Figure 1, the distance d7 between the surface of the first light-transmitting component 600, which is away from the third part 330, and the boundary of the display area AA is 0 to 0.4 mm.

[0300] For example, the distance d7 between the surface of the first light-transmitting component 600 away from the third portion 330 and the boundary of the display area AA is 0 mm, 0.05, 0.1 mm, 0.12 mm, 0.18 mm, 0.2 mm, 0.23 mm, 0.27 mm, 0.3 mm, 0.33 mm, 0.35 mm or 0.4 mm.

[0301] In some embodiments, as shown in FIG2, the display module 1000 further includes a first bezel 1100 and a second bezel 1200. The first bezel 1100 surrounds the middle frame 300 and the side panel 220, and is connected to the middle frame 300 and the back panel 200. The second bezel 1200 is located on the side of the first bezel 1100 near the first portion 310, and abuts against the surface of the display panel 100 away from the diffuser plate 500.

[0302] In this configuration, the first border 1100 and the second border 1200 can fix and protect the display module 1000.

[0303] In some examples, common materials for the first frame 1100 and the second frame 1200 include hot-dip galvanized steel sheet (e.g., GCC) and stainless steel (e.g., SUS304).

[0304] In some embodiments, the surface of the second bezel 1200 near the first portion 310 is located within the peripheral area BB in the orthographic projection onto the display panel 100.

[0305] With this configuration, the second bezel 1200 will not block the light emitted from the display area AA in the display panel 100.

[0306] In some examples, the distance d8 between the surface of the second border 1200 near the first portion 310 and the boundary of the display area AA is 0 to 0.2 mm.

[0307] This configuration allows for a smaller distance between the surface of the second bezel 1200 near the third portion 330 and the boundary of the display area AA, reducing the risk of light escaping from the peripheral area BB and improving the display effect of the display panel 100.

[0308] For example, the distance d8 between the surface of the second border 1200 near the third portion 330 and the boundary of the display area is 0 mm, 0.1 mm or 0.2 mm.

[0309] In some embodiments, as shown in FIG2, the display module 1000 further includes a plurality of fasteners 1300. The plurality of fasteners 1300 are located on the side of the first portion 310 near the side panel 220, and are fixedly connected to the first frame 1100, the middle frame 300, and the side panel 220. The plurality of fasteners 1300 includes a first fastener 1301, which is the fastener 1300 with the smallest distance from the display panel 100 among the plurality of fasteners 1300. The distance d9 between the first fastener 1301 and the surface of the display panel 100 away from the base plate 210 is less than or equal to 10 mm.

[0310] With this configuration, the first fastener 1301 can provide sufficient fixing force, which can reduce the risk of the second frame 1200 turning outward.

[0311] In some examples, the fastener 1300 includes a screw, in which case the outer side of a portion of the first frame 1100 is recessed to form a recess, a first through hole is provided in the recess, and a first threaded hole is provided on the side plate 220 to mate with the first through hole.

[0312] In addition, the middle frame 300 also includes a fourth part 350, which is located between the first frame 1100 and the side plate 220. The fourth part 350 is provided with a second through hole that mates with the first through hole and the first threaded hole. Screws are used to fix the first frame 1100, the middle frame 300 and the back plate 200 together through the first through hole, the second through hole and the first threaded hole.

[0313] In some embodiments, the inventors have found that the height of the first light-transmitting component 600 can be increased by increasing the distance d9 between the first fastener 1301 and the surface of the display panel 100 away from the base plate 210. However, if the distance between the first fastener 1301 and the surface of the display panel 100 away from the base plate 210 is too large, it will cause the second frame 1200 to flip over.

[0314] For example, by simulation, the fixing point of the back plate 200 and the first fixing member 1301 is moved closer to the base plate 210 to meet the overall support structure strength and the limit range of the second frame 1200 not turning outward. First, the simulation object is simplified. The main simulation content is to ensure that when the height of the first fixing member 1301 decreases, the outward turning amount of the second frame 1200 is less than 0.5mm (the distance from the display area AA to the edge of the display panel 100) during normal use. If it exceeds 0.5mm, the outward turning amount of the second frame 1200 is too large, which may cause the display panel 100 to jump off. The simplified model retains the back plate 200, the first frame 1100 and the second frame 1200, and fixes them at the position of the first fixing member 1301, and applies torque to the back plate 200.

[0315] The outward turning amount of the second frame 1200 varies depending on the distance d9 from the first fixing member 1301 to the surface of the display panel 100 away from the base plate 210. See Table 2 below for details.

[0316] Table 2

[0317] The locking height of the first fastener 1301 in Table 2 is the distance d9 between the first fastener 1301 and the surface of the display panel 100 away from the base plate 210. The results show that, in order to satisfy the maximum outward flare of the second frame 1200 of 0.5mm, the maximum distance d9 between the first fastener 1301 and the surface of the display panel 100 away from the base plate 210 is 10mm. At this time, the maximum height of the first light-transmitting component 600 in the direction perpendicular to the base plate 210 is 7mm. As shown in Figure 24, the left image in Figure 24 is a schematic diagram without shortening the distance between the first screw hole and the base plate 210, and the right image in Figure 24 is a schematic diagram after shortening the distance between the first screw hole and the base plate 210.

[0318] A simulation was performed on the first fastener 1301 with a locking height of 7mm. The simulation results are shown in Figure 25, where curve 3002 represents the simulated brightness curve. The horizontal axis in Figure 25 represents the distance to the screen edge (0mm represents the screen edge), and the vertical axis represents the relative brightness ratio. As shown by curve 3002 in Figure 25, the brightness at a distance of 5mm from the edge is 95%.

[0319] A simulation was performed on the first fastener 1301 with a locking height of 10mm. The simulation results are shown in Figure 25, where curve 3001 represents the simulated brightness curve. As shown by curve 3001 in Figure 25, the brightness at a position 5mm from the edge is 98%.

[0320] As can be seen from curves 3001 and 3002 in Figure 25, after increasing the height of the first light-transmitting component 600, the brightness at a position 5mm from the edge increased by 3%.

[0321] In some embodiments, as shown in FIG22F, the orthographic projection of the surface of the third portion 330 near the first light-transmitting component 600 on the display panel 100 is a sixth distance d10 with respect to the boundary of the display area AA, and the orthographic projection of the surface of the second frame 1200 near the first portion 310 on the display panel 100 is a seventh distance d11 with respect to the boundary of the display area AA. The sixth distance d10 is greater than the seventh distance d11.

[0322] In some other embodiments, as shown in FIG26, the display device 2000 further includes a first frame 1100 and a plurality of fasteners 1300. The first frame 1100 surrounds the middle frame 300 and the side panel 220, and one end of the first frame 1100 away from the bottom plate 210 extends out of the display panel 100. The portion of the first frame 1100 extending out of the display panel 100 is bonded to the surface of the display panel 100 away from the bottom plate 210.

[0323] Multiple fasteners 1300 are located on the side of the first part 310 near the side plate 220, and the fasteners 1300 are fixedly connected to the first frame 1100, the middle frame 300 and the side plate 220.

[0324] In some examples, the plurality of fasteners 1300 includes a first fastener 1301, which is the fastener 1300 with the smallest distance from the display panel 100 among the plurality of fasteners 1300, and the distance d9 between the first fastener 1301 and the surface of the display panel 100 away from the base plate 210 is less than or equal to 11.5 mm.

[0325] This configuration allows for a higher height of the first light-transmitting component 600, increasing the amount of light entering the edge area of ​​the diffuser plate 500 and reducing the risk of partial darkening of the corresponding edge area of ​​the display device 2000.

[0326] In some examples, the fastener 1300 includes a screw, in which case the outer side of a portion of the first frame 1100 is recessed to form a recess, a first through hole is provided in the recess, and a first threaded hole is provided on the side plate 220 to mate with the first through hole.

[0327] In addition, the middle frame 300 also includes a fourth part 350, which is located between the first frame 1100 and the side plate 220. The fourth part 350 is provided with a second through hole that mates with the first through hole and the first threaded hole. Screws are used to fix the first frame 1100, the middle frame 300 and the back plate 200 together through the first through hole, the second through hole and the first threaded hole.

[0328] In some embodiments, as shown in FIG2, the display module 1000 includes a reflective sheet 1400, which has a plurality of third through holes 1401, through which a light source 420 passes. In this case, as shown in FIG8, the fourth distance d4 refers to the distance between the reflective sheet 1400 and the third surface 630.

[0329] Based on this, as shown in Figure 2, the middle frame 300 also includes a limiting block 360, which is located on the side of the reflective sheet 1400 close to the display panel 100 and is used to limit and fix the reflective sheet 1400.

[0330] In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0331] The above are merely specific embodiments of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
