Description
Technical Field
[0001] This application relates to the field of display devices, and in particular to a near-eye display device. Background Technology
[0002] Augmented Reality (AR) display is an emerging display technology that overlays real-world information and virtual information onto the same screen or space in real time. When users wear appropriate near-eye display devices, their eyes can receive natural ambient light and virtual images superimposed on the natural environment in real time, achieving a sensory experience that transcends reality. Typically, in practical applications, AR displays are achieved through near-eye display devices such as AR glasses.
[0003] However, existing near-eye display devices suffer from insufficient heat dissipation performance. Summary of the Invention

[0015] In some embodiments, the first heat dissipation platform is connected to the second heat dissipation platform, and the first heat dissipation platform and the second heat dissipation platform are L-shaped.
[0016] In some embodiments, the heat dissipation component is connected to the outer shell wall via a sliding fit, allowing the heat dissipation base to be detachably mounted on the temple; the outer shell wall includes a first slide rail component located on its inner surface, and the heat dissipation component includes a second slide rail component located on the side of the first heat dissipation platform near the outer shell wall, with the first slide rail component and the second slide rail component being detachably slidably fitted; or,
[0017] The heat dissipation component is connected to the outer shell wall by a locking mechanism, so that the heat dissipation base can be detachably installed on the temple.
[0018] In some embodiments, the heat dissipation component is connected to the outer shell wall via a sliding fit.
[0019] One of the first slide rail component and the second slide rail component is a guide groove, and the other is a guide rail portion.

[0023] The material of the first heat sink sub-component includes thermally conductive adhesive or thermally conductive pad; and / or,

[0025] In some embodiments, the near-eye display device further includes:
[0026] A first adhesive part is located at the connection between the heat dissipation component and the outer shell wall, and the heat dissipation component and the outer shell wall are fixedly connected through the first adhesive part.
[0027] In some embodiments, the display component includes a carrier sub-component, and a first color microdisplay, a second color microdisplay, and a third color microdisplay, the first color microdisplay, the second color microdisplay, and the third color microdisplay emitting light of different colors;

The heat dissipation component includes a heat dissipation base and a first heat dissipation sub-part, with the heat dissipation base detachably mounted on the temples. The display component is mounted on the heat dissipation base via the first heat dissipation sub-part. Firstly, when the display component generates a large amount of heat, it dissipates heat directly through the first heat dissipation sub-part, the heat dissipation base, and other components of the temples, rather than through indirect heat dissipation via air. This forms a rapid heat dissipation channel from the inside to the outside, specifically a bidirectional heat conduction path from the display component / microdisplay to the heat dissipation component and then to the temple housing / first housing, which improves the heat dissipation efficiency and speed of the near-eye display device. Secondly, display components of different sizes can be mounted on the heat dissipation base. For example, the near-eye display device can mount display components of different sizes on a heat dissipation base of the same size / type, enabling near-eye display devices with different display components to be compatible with existing external components and internal structures. Thirdly, the heat sink base is detachably mounted on the temple, and the display component is mounted on the heat sink base via the first heat sink sub-unit. When the display component needs to be replaced, both the display component and the heat sink base can be replaced directly, avoiding damage to other components when the display component is destructively removed. Each replacement of the display component does not require re-molding or modification of the shell design, reducing the development cycle and lowering costs, which is particularly effective for demonstration prototypes and small-batch trial production. Fourthly, when there are manufacturing errors in the heat sink component, the first heat sink sub-unit eliminates / tolerates and absorbs manufacturing tolerances and assembly errors, avoiding unstable heat dissipation performance due to dimensional differences in metal parts such as the heat sink component. The embodiments of this application have at least one of the above-mentioned beneficial effects. Attached Figure Description

[0047] Existing near-eye display devices suffer from insufficient heat dissipation performance.

Figure 2 This diagram illustrates the heat dissipation component 30 before installation. Figure 3 The diagram illustrates the heat dissipation component 30 after installation. Figure 4 This diagram illustrates the heat dissipation component 30 and the display component 40 after installation. Figures 1 to 6 All can be Figure 7 A schematic diagram of a partial or partial structure of a near-eye display device.
[0051] Firstly, such as Figures 1 to 5 As shown, and in combination Figure 7 As shown, this application provides a near-eye display device 100, which includes a frame 101, at least one heat dissipation component 30, and at least one display component 40. The frame 101 includes a lens frame 10 and two temples 20, with the front ends of the two temples 20 respectively connected to the two ends of the lens frame 10; the heat dissipation component 30 includes a heat dissipation base 31 and a first heat dissipation sub-part Q1, with the heat dissipation base 31 detachably mounted on the temples 20; the display component 40 is mounted on the heat dissipation base 31 via the first heat dissipation sub-part Q1.
[0052] For example, the near-eye display device 100 can be Figure 7 The AR glasses shown include a near-eye display device 100 comprising a frame 101, which includes a lens frame 10 and two temples 20. A lens 50 is disposed within the frame 101. Two temples 20 are respectively disposed on the left and right sides of the frame 101. The two temples 20 can be a left temple 201 and a right temple 202. One end of the left temple 201 and the right temple 202 is fixedly connected to the lens frame 10 or movably connected. Movable connections include, but are not limited to, hinge connections or pivot connections. When the near-eye display device 100 is in use, the two temples 20 are positioned on either side of the user's face and rest on the ears to support the temples. The pressure of the temples 20 on the user's face ensures the stability of the near-eye display device 100.
[0053] For example, in some embodiments, the near-eye display device 100 can create virtual images in a monocular or binocular field of view. Near-eye display is a technology that renders light field information to the human eye through a display device placed within the non-visual distance of the human eye, thereby reconstructing a virtual scene in front of the eyes. The near-eye display device 100 generally has an optical engine, which includes optical components and a display component 40. The optical components can be optical lenses or combinations of optical lenses. The display component 40 can be a microdisplay, which provides display content to the device. The microdisplay can be a self-emissive active device, such as a micro-OLED (µOLED) or micro-LED (µLED), or a liquid crystal display (including transmissive Liquid Crystal Display (LCD) and reflective Liquid Crystal on Silicon (LCOS), as well as a digital micromirror array (DMD, i.e., the core of Digital Light Processing (DLP)) and a linear beam scanner (LBS) based on microelectromechanical systems (MEMS) technology. The type of display component 40 is not limited to these.
[0054] For example, in some embodiments, the near-eye display device 100 may include a heat dissipation component 30 and a display component 40, which are disposed within a receiving space 21Q of a temple 20.
[0055] For example, in some other embodiments, the near-eye display device 100 may include two heat dissipation components 30 and two display components 40, with a heat dissipation component 30 and a display component 40 disposed in the receiving space 21Q of each temple 20.
[0056] For example, the heat dissipation component 30 can be a one-piece molded structure, but is not limited to this.
[0057] For example, in the prior art, to meet different application scenarios (such as outdoor, high-brightness environments, or long-term wear), manufacturers often need to evaluate and test multiple specifications of display components 40. During the product development and demonstration phase, it is often necessary to quickly switch between different display components 40 to verify optical performance, power consumption, and thermal characteristics in order to accelerate product iteration. However, the different sizes, mounting holes, thicknesses, and heat dissipation requirements of different display components 40 make it difficult for existing exterior components and internal structures to be compatible; each time the display component 40 is replaced, it is necessary to re-mold or modify the design of the outer shell (first shell 21), resulting in extended development cycles and increased costs, which is particularly detrimental to demonstration prototypes and small-batch trial production.
[0058] In this embodiment, the near-eye display device 100 includes a frame 101, at least one heat dissipation component 30, and at least one display component 40. The frame 101 includes a lens frame 10 and two temples 20, with the front ends of the two temples 20 respectively connected to the two ends of the lens frame 10. The heat dissipation component 30 includes a heat dissipation base 31 and a first heat dissipation sub-part Q1, with the heat dissipation base 31 detachably mounted on the temples 20. The display component 40 is mounted on the heat dissipation base 31 via the first heat dissipation sub-part Q1. In a first aspect, when the display component 40 generates a large amount of heat, the display component 40 dissipates heat directly through the first heat dissipation sub-part Q1, the heat dissipation base 31, and other components of the temples 20, rather than through indirect heat dissipation via air. This forms a rapid heat dissipation channel from the inside to the outside, specifically forming a bidirectional heat conduction path from the display component 40 / microdisplay to the heat dissipation component 30 to the temple 20 housing / first housing 21, which can improve the heat dissipation efficiency and speed of the near-eye display device 100. Secondly, display components 40 of different sizes can be installed on the heat dissipation base 31. For example, near-eye display devices 100 can install display components 40 of different sizes on heat dissipation bases 31 of the same size / type, realizing that near-eye display devices 100 with different display components 40 can be compatible with existing exterior parts and internal structures. Thirdly, the heat dissipation base 31 is detachably installed on the temple 20, and the display component 40 is installed on the heat dissipation base 31 through the first heat dissipation sub-part Q1. When the display component 40 needs to be replaced, the display component 40 and the heat dissipation base 31 can be replaced directly, avoiding damage to other components when the display component 40 is destructively removed. Each time the display component 40 is replaced, there is no need to re-mold or modify the shell design, which reduces the development cycle and lowers costs, and is particularly effective for demonstration prototypes and small-batch trial production. Fourthly, when there are manufacturing errors in the heat dissipation component 30, the first heat dissipation sub-part Q1 eliminates / tolerates and absorbs manufacturing tolerances and assembly errors, avoiding unstable heat dissipation performance due to dimensional differences in metal parts such as the heat dissipation component 30. The embodiments of this application have at least one of the above-mentioned beneficial effects.
[0059] In some implementations, such as Figures 2 to 5 As shown, the heat dissipation base 31 includes at least one heat dissipation platform 31s, and the display component 40 is mounted on the heat dissipation platform 31s via the first heat dissipation sub-part Q1.
[0060] For example, such as Figures 2 to 5 As shown, the heat dissipation platform 31s can achieve surface contact heat dissipation over a large area, thereby increasing the heat dissipation area and improving heat dissipation efficiency and speed.
[0061] In some embodiments, the temple 20 includes a first housing 21 and a receiving space 21Q enclosed by the first housing 21. The display component 40 and the heat dissipation component 30 are disposed within the receiving space 21Q. In a first direction X, the first housing 21 includes an outer housing wall 211 that is away from the other temple 20. The first direction X is parallel to the direction in which one temple 20 points to the other temple 20. At least one heat dissipation platform 31s includes a first heat dissipation platform 31s1, which is located on the side of the display component 40 near the outer housing wall 211.
[0062] For example, the first outer shell 21 is the temple shell or the outer shell of the temple. The front end of the temple 20 is connected to one end of the frame 10, including but not limited to the front end of the first outer shell 21 being connected to one end of the frame 10, and one end of the first outer shell 21 / outer shell wall 211 being fixedly connected to or movably connected to the frame 10. The movable connection includes but is not limited to a pivot connection or a hinge connection. The outer shell wall 211 is the part of the first outer shell 21 of one temple 20 that is away from the other temple 20, and the inner shell wall 214 is the part of the first outer shell 21 of one temple 20 that is close to the other temple 20.
[0063] For example, the first direction X is parallel to the direction from one temple 20 to the other temple 20 (when the two temples 20 are unfolded). When the user wears the near-eye display device 100, the outer shell wall 211 is away from the bridge of the nose / face. The first direction X can be horizontal, but is not limited to this.
[0064] For example, in the first direction X, the first housing 21 includes an outer housing wall 211 of one temple 20 away from the other temple 20, and an inner housing wall 214 close to the other temple 20. Figure 7 The diagram illustrates the outer shell wall 211 and inner shell wall 214 of the right temple 202. When the user wears the near-eye display device 100, the inner shell wall 214 is close to the bridge of the nose / face.
[0065] For example, in some embodiments, the first outer shell 21 includes an upper shell wall 213, an outer shell wall 211, a lower shell wall 212, and an inner shell wall 214, which can be sequentially connected to form an accommodating space 21Q. The upper shell wall 213, the outer shell wall 211, the lower shell wall 212, and the inner shell wall 214 are all parts of the first outer shell 21.
[0066] For example, the heat dissipation platform 31s includes a first heat dissipation platform 31s1, which is located on the side of the display component 40 near the outer shell wall 211. This allows the heat from the display component 40 to be directly dissipated to the outside through the first heat dissipation sub-part Q1, the heat dissipation base 31, and other components of the temple 20. When the user wears the near-eye display device 100, heat is prevented from being dissipated towards the user's nose / face, thus improving the safety performance of the near-eye display device 100.
[0067] In some embodiments, in a direction perpendicular to the first direction X, the first housing 21 includes a lower housing wall 212; at least one heat dissipation platform 31s also includes a second heat dissipation platform 31s2, the second heat dissipation platform 31s2 being located on the side of the display component 40 near the lower housing wall 212, the lower housing wall 212 supporting the display component 40.
[0068] For example, the direction perpendicular to the first direction X is the second direction Y. When the user wears the near-eye display device 100, the second direction Y can be a vertical direction, but it is not limited to this.
[0069] For example, in a direction perpendicular to the first direction X, the first outer shell 21 includes a lower shell wall 212 and an upper shell wall 213 away from the lower shell wall 212.
[0070] For example, in a direction perpendicular to the first direction X, the second heat dissipation platform 31s2 is located on the side of the display component 40 near the lower shell wall 212. The lower shell wall 212 supports the display component 40, so that the lower shell wall 212 can support the display component 40. When the user wears the near-eye display device 100, the display component 40 is prevented from becoming loose or falling off, thus improving reliability.
[0071] In some implementations, such as Figure 2 and Figure 3 As shown, the first heat dissipation platform 31s1 is connected to the second heat dissipation platform 31s2, and the first heat dissipation platform 31s1 and the second heat dissipation platform 31s2 are L-shaped.
[0072] For example, such as Figure 2 and Figure 3 As shown, the first heat dissipation platform 31s1 is connected to the second heat dissipation platform 31s2, and the first heat dissipation platform 31s1 and the second heat dissipation platform 31s2 are L-shaped. The first heat dissipation sub-part Q1 may include a first sub-heat dissipation sub-part Q11 and a second sub-heat dissipation sub-part Q12. The display component 40 is connected to the first heat dissipation platform 31s1 through the first sub-heat dissipation sub-part Q11, and the display component 40 is connected to the second heat dissipation platform 31s2 through the second sub-heat dissipation sub-part Q12.
[0073] For example, in some embodiments, the first heat dissipation platform 31s1 is connected to the second heat dissipation platform 31s2, the first heat dissipation platform 31s1 and the second heat dissipation platform 31s2 are L-shaped, and the first sub-heat dissipation sub-part Q11 and the second sub-heat dissipation sub-part Q12 can be connected as one unit, thereby increasing the heat dissipation area and improving the heat dissipation speed and efficiency.
[0074] For example, in some other embodiments, the first sub-heat dissipation sub-part Q11 and the second sub-heat dissipation sub-part Q12 can be arranged at intervals to facilitate the installation of the display component 40 and avoid adhesive overflow. Figure 2 and Figure 3 This illustrates that the first sub-heat sink Q11 and the second sub-heat sink Q12 can be set at intervals.
[0075] In some implementations, such as Figure 2 and Figure 3 As shown, the heat dissipation component 30 is connected to the outer shell wall 211 by a sliding fit, so that the heat dissipation base 31 can be detachably installed on the temple 20; the outer shell wall 211 includes a first slide rail component 21h located on the inner surface, and the heat dissipation component 30 includes a second slide rail component 30h located on the side of the first heat dissipation platform 31s1 near the outer shell wall 211, and the first slide rail component 21h and the second slide rail component 30h are detachably slidably fitted; or, the heat dissipation component 30 is connected to the outer shell wall 211 by a locking method, so that the heat dissipation base 31 can be detachably installed on the temple 20.
[0076] For example, such as Figure 2 and Figure 3 As shown, the heat dissipation component 30 includes a second slide rail component 30h located on the side of the first heat dissipation platform 31s1 near the outer shell wall 211, and the second slide rail component 30h is connected to the first heat dissipation platform 31s1.
[0077] For example, such as Figure 2 and Figure 3 As shown, the installation and removal of the heat dissipation component 30 can be facilitated by the first slide rail component 21h and the second slide rail component 30h.
[0078] For example, such as Figure 2 and Figure 3 As shown, the first slide rail component 21h and the second slide rail component 30h can be mutually fitted and slidably arranged.
[0079] For example, such as Figure 2 and Figure 3 As shown, the first slide rail component 21h can be a sliding track / protrusion, and the second slide rail component 30h can be a sliding groove, but is not limited to these.
[0080] For example, the heat dissipation component 30 is connected to the outer shell wall 211 by a locking method, which may include any one of the following: threaded connection, snap-lock connection, and knob / quick-release locking connection.
[0081] In some implementations, such as Figure 2 and Figure 3 As shown, the heat dissipation component is connected to the outer shell wall by a sliding fit; one of the first slide rail component and the second slide rail component is a guide groove and the other is a guide rail part, and the cross-sectional shape of the guide groove and the guide rail part is any one of the rectangle, trapezoid, T-shape, dovetail shape and circle.
[0082] For example, in the first and second slide rail components, one is a guide groove and the other is a guide rail portion. The cross-sectional shape of the guide groove and the guide rail portion is any one of rectangular, trapezoidal, T-shaped, dovetail, and circular. When the cross-sectional shape of the guide groove and the guide rail portion is dovetail-shaped, the first slide rail component 21h and the second slide rail component 30h are detachable dovetail groove fits; when the cross-sectional shape of the guide groove and the guide rail portion is T-shaped, the first slide rail component 21h and the second slide rail component 30h are detachable T-shaped groove fits.
[0083] In some implementations, such as Figure 2 and Figure 3 As shown, the heat dissipation component 30 also includes a second heat dissipation sub-component Q2, and the heat dissipation base 31 is connected to the frame 101 near the front end of the temple 20 through the second heat dissipation sub-component Q2.
[0084] For example, the heat dissipation base 31 is connected to the frame 101 near the front end of the temple 20 via the second heat dissipation sub-part Q2, which can further fix or detachably connect the heat dissipation component 30 to the frame 101. At the same time, the second heat dissipation sub-part Q2 can also form a heat dissipation channel. The heat dissipation base 31, the second heat dissipation sub-part Q2 and the frame 101 form a heat dissipation channel, which improves heat dissipation efficiency and speed.
[0085] In some embodiments, the first heat dissipation sub-part Q1 is made of thermoplastic material; and / or, the second heat dissipation sub-part Q2 is made of thermoplastic material; and / or, the material of the first heat dissipation sub-part Q1 includes thermally conductive adhesive or thermally conductive pad; and / or, the material of the second heat dissipation sub-part Q2 includes thermally conductive adhesive or thermally conductive pad.
[0086] For example, the first heat sink sub-part Q1 is made of thermoplastic material, which can be melted by heating, so that the heat sink component 30 and the display component 40 can be disassembled and reworked, and the heat sink component 30 and the display component 40 can be separated.
[0087] For example, the second heat dissipation sub-part Q2 is made of thermoplastic material, which can be melted by heating, so that the heat dissipation component 30 and the frame 101 can be disassembled and reworked, and the heat dissipation component 30 and the frame 101 can be separated.
[0088] In some embodiments, the near-eye display device 100 further includes a first adhesive part Q01, which is located at the connection between the heat dissipation component 30 and the outer shell wall 211, and the heat dissipation component 30 and the outer shell wall 211 are fixedly connected by the first adhesive part Q01.
[0089] For example, such as Figure 2 As shown by the dashed circle, the near-eye display device 100 may further include a first adhesive sub-part Q01. The first adhesive sub-part Q01 is located at the connection between the heat dissipation component 30 and the outer shell wall 211. The heat dissipation component 30 and the outer shell wall 211 are fixedly connected by the first adhesive sub-part Q01. For example, the first adhesive sub-part Q01 is formed by applying adhesive between the first slide rail component 21h and the second slide rail component 30h. The first adhesive sub-part Q01 can fix the heat dissipation component 30 to the outer shell wall 211 and prevent the heat dissipation component 30 from becoming loose. The material of the first adhesive sub-part Q01 can be a thermally conductive adhesive or a thermoplastic material, which facilitates the replacement and rework of the heat dissipation component 30.
[0090] For example, the material of the first heat dissipation sub-part Q1 is a thermally conductive adhesive (first heat dissipation adhesive) or a thermally conductive pad (thermal conductive pad, first heat dissipation pad) with thermal conductivity, but is not limited thereto; the material of the second heat dissipation sub-part Q2 is a thermally conductive adhesive (second heat dissipation adhesive) or a thermally conductive pad (thermal conductive pad, second heat dissipation pad) with thermal conductivity, but is not limited thereto. The material of the first adhesive sub-part Q01 is a thermally conductive adhesive (third heat dissipation adhesive), for example, the material of the first adhesive sub-part Q01 is a thermoplastic adhesive, but is not limited thereto.
[0091] In some implementations, such as Figure 4 and Figure 5 As shown, the display component 40 includes a carrier sub-component 41, and a first color microdisplay 42, a second color microdisplay 43, and a third color microdisplay 44, which emit light of different colors; the first color microdisplay 42, the second color microdisplay 43, and the third color microdisplay 44 are mounted on different side surfaces of the carrier sub-component 41.
[0092] For example, the display component 40 includes a carrier sub-part 41, and a first color microdisplay 42, a second color microdisplay 43, and a third color microdisplay 44. The carrier sub-part 41 may be a part of an optomechanical or optical component, but is not limited thereto.
[0093] For example, the first color microdisplay 42 includes a plurality of first color subpixels, the second color microdisplay 43 includes a plurality of second color subpixels, and the third color microdisplay 44 includes a plurality of third color subpixels, wherein the first color subpixels, the second color subpixels, and the third color subpixels emit light of different colors.
[0094] For example, the first color microdisplay 42, the second color microdisplay 43, and the third color microdisplay 44 may emit red light, green light, and blue light, respectively, but are not limited thereto.
[0095] For example, the light emitted by the first color microdisplay 42, the second color microdisplay 43, and the third color microdisplay 44 can be combined into a color image by an optomechanical or optical component.
[0096] It should be noted that in some other embodiments, the display component 40 in one temple 20 may include only one microdisplay. In other embodiments, the display component 40 in one temple 20 may include only two microdisplays.
[0097] In some embodiments, the shape and size of the heat sink 31 can be changed according to the shape and size of the display component 40.
[0098] For example, when the display component 40 and / or the heat sink 31 need to be replaced, or when the shape and size of the display component 40 and / or the heat sink 31 change, the display component 40 and / or the heat sink 31 can be directly replaced. Since the shape and size of the heat sink 31 can be changed according to the shape and size of the display component 40, each replacement of the display component 40 and / or the heat sink 31 does not require re-molding or modification of the shell design. It can be adapted to different models of frame 101, is compatible with existing appearances, reduces the development cycle and lowers costs, and is particularly effective for demonstration prototypes and small-batch trial production.
[0099] In some embodiments, at least one of the first color microdisplay 42, the second color microdisplay 43, and the third color microdisplay 44 is mounted on the heat sink base 31 via the first heat sink sub-part Q1.
[0100] For example, at least one of the first color microdisplay 42, the second color microdisplay 43, and the third color microdisplay 44 is mounted on the heat sink base 31 via the first heat sink sub-part Q1. For instance, the second color microdisplay 43 is mounted on the first heat sink platform 31s1 via the first heat sink sub-part Q1. The microdisplay is in direct contact with the first heat sink sub-part Q1, which can improve heat dissipation efficiency and speed.
[0101] For example, in some embodiments, at least two of the first color microdisplay 42, the second color microdisplay 43, and the third color microdisplay 44 are mounted on the heat sink base 31 via the first heat sink sub-part Q1. This can increase the heat dissipation surface of the display component 40, increase the heat dissipation area of the display component 40, and improve heat dissipation efficiency and speed.
[0102] For example, the material of the heat dissipation component 30 can be a metal with high thermal conductivity (high thermal conductivity coefficient), such as aluminum, copper, silver, aluminum alloy, magnesium alloy, etc.
[0103] For example, Figure 6 The heat dissipation effect of Comparative Examples 1 and 2 of the prior art was compared with that of Sample 1 of the present application. In Comparative Example 1, the display component is directly fixed to the frame 10 or temple 20, and there is no gap between the display component and the outer shell wall 211, so air convection heat dissipation cannot be formed. In Comparative Example 2, there is a gap between the display component and the outer shell wall 211, which allows air convection heat dissipation. In Sample 1, the aforementioned heat dissipation component 30 is provided between the display component 40 and the outer shell wall 211. Figure 6 The vertical axis represents the average temperature of the first color microdisplay 42, the second color microdisplay 43, and the third color microdisplay 44. After Comparative Examples 1, 2, and Sample 1 displayed the same image for the same period of time, the temperature was... Figure 6 As can be seen, compared to Comparative Example 1 and Comparative Example 2, Sample 1 has better heat dissipation and a lower temperature. It should be noted that in Sample 1, the blue-light-emitting microdisplay is bonded to the first heat dissipation platform 31s1 via the first heat dissipation sub-unit Q1. The temperature of the blue-light-emitting microdisplay in Comparative Example 2 was 50 degrees Celsius, while the temperature of the blue-light-emitting microdisplay in Sample 1 was 41 degrees Celsius, representing a 36% improvement in heat dissipation, which is significant.
