[0061] For ease of description and understanding, the display device is used in a vertical position. The vertical direction is the up-down direction, the direction facing the user is the front, the direction facing away from the user is the back, and the width of the display device is the left-right direction. The front side is the side of the display device that displays image information, and the direction facing away from the front side is the back. In this application, the front side is the front.

[0062] Figure 1 It is a structural schematic diagram of the display device of the utility model from one viewing angle. Figure 2 It is a structural schematic diagram of the display device of the utility model from one viewing angle.

[0063] See Figure 1 and Figure 2 This embodiment provides a display device, which mainly includes a back plate 100, a display panel 200 mounted on the front of the back plate 100, and a rear cover 300 detachably mounted on the back of the back plate 100. The display device is a television or a computer monitor, etc., and the following description takes a television as an example.

[0064] A light source and an optical film assembly are located between the backplane 100 and the display panel 200. These light source, optical film assembly, and display panel 200 are arranged in this order from back to front. Light from the light source passes through the optical film assembly and is projected onto the display panel 200. The display panel 200 then displays image information. The front side of the display panel 200 serves as the display surface.

[0065] The backplate 100 is the primary support for the display device and is oriented vertically. A forward-projecting bezel is formed around the perimeter of the backplate 100. This bezel extends around the perimeter of the backplate 100. The bezel extends forward beyond the front side of the backplate 100. Together, the bezel and backplate 100 form a mounting cavity with an open front for mounting the backlight and optical film assembly. The display panel 200 is secured to the front end of the bezel.

[0066] In this embodiment, the back plate 100 is made of a metal material, such as iron or aluminum alloy. By making the back plate 100 of a metal material, the back plate 100 has a smaller thickness while ensuring the structural strength of the back plate 100, thereby enabling the display device to be designed to be thinner.

[0067] The light source is used to emit light. The light source and the optical film group are arranged in parallel. The light source is located on the light incident side behind the optical film group to emit light toward the optical film group. The optical film group is located in front of the backlight source so that after the light passes through the optical film group, uniform white light can be obtained on the light exit side in front of the optical film group.

[0068] The backlight is an LED light panel, which is attached to the bottom surface of the mounting cavity and emits white light forward toward the optical film assembly. In some embodiments, a vertical gap exists between the backlight and the optical film assembly to form a light mixing distance. In other embodiments, the backlight and the optical film assembly are attached vertically.

[0069] The optical film assembly is positioned in front of the backlight, separated from the backlight by a gap, to improve the uniformity and brightness of the light source. The optical film assembly includes a diffuser plate and multiple films arranged in sequence. The multiple films may include a brightness enhancement film and multiple prism sheets, or multiple prism sheets.

[0070] The display panel 200 is located in front of the optical film group. The light in the optical film group is transmitted forward to the display panel 200. The liquid crystal molecules in the display panel 200 are stimulated by the electric field and deflected, reducing the transmission rate of the light emitted by the optical film group to the liquid crystal panel, and then projecting the light into filters of different colors to form an image.

[0071] The rear housing 300 is located behind the back panel 100. A chamber is formed between the front of the rear housing 300 and the rear of the back panel 100. The chamber houses the motherboard, power board, and other driver components. These components are located within the enclosure of the rear housing 300, protecting them from damage.

[0072] The mainboard is mainly used to calculate the control system of the display device and output relevant operation instructions. The mainboard has a large number of electronic components, which mainly transmit the operation instructions output by the mainboard to the corresponding operation terminal.

[0073] The power board is separately provided or integrated on the main board and fixed on the back of the back plate 100. It is mainly used to provide driving voltage or stable working voltage to the main board and keep the output current stable when the circuit on the main board is working.

[0074] Other driving components include a speaker 600 and a power strip. The speaker 600 is located on the back of the back panel 100 and is primarily used to produce sounds corresponding to the interface displayed on the display panel 200. The power strip is equipped with multiple different types of interfaces for connecting to external devices, receiving signals from external devices, or outputting signals to external devices. In some embodiments, the power strip is integrated into the mainboard. Other driving components may include a remote control module or a voice module.

Figure 6 This is a schematic diagram of the connection of the side frame 400 of the present invention on the display device. Figure 7 This Figure 5 Enlarged view of point A in the middle.

[0076] See Figures 3 to 6 The back of the back plate 100 is connected to a side frame 400 , and the side frame 400 is set at the left and right edges of the back plate 100 .

[0077] The back of the back plate 100 protrudes backward to form a flange 110 . The flange 110 is close to the left and right sides of the back plate 100 , and the side frame 400 is fixed on the flange 110 .

[0078] In some embodiments, flanges 110 are provided on the left and right sides of the back plate 100. In other embodiments, flanges 110 are provided on the upper and lower edges and the left and right edges of the back plate 100.

[0079] In some embodiments, the flange 110 is not provided on the back surface of the back plate 100 , and the side frame 400 is directly fixed to the back surface of the back plate 100 .

[0080] The back plate 100 is provided with fastening holes 120 for fixing the side frame 400. The fastening holes 120 are provided on the flange 110. Fasteners pass through the side frame 400 and the fastening holes 120 to fix the side frame 400 to the back plate 100. The fasteners are bolts or screws.

[0081] A plurality of fastening holes 120 are provided, and the plurality of fastening holes 120 are arranged at intervals in the vertical direction, so that the side frame 400 is fixed to the back plate 100 more firmly and reliably.

[0082] In some embodiments, the side frame 400 can also be fixed to the back side of the back plate 100 by snapping or other means.

[0083] Figure 8 It is a structural schematic diagram of the side frame 400 of the present invention from one perspective. Figure 9 It is a structural schematic diagram of the side frame 400 of the present invention from another perspective.

[0084] See Figures 3 to 9 The side frames 400 are fixed to the left and right sides of the back of the back plate 100. The side frames 400 extend vertically, and the upper and lower ends of the side frames 400 are respectively close to the upper and lower ends of the back plate 100, so that the side frames have sufficient length in the vertical direction to install various components.

[0085] The side frame 400 is provided with via holes 410, which correspond to the fastening holes 120 on the back panel 100. Fasteners pass through the via holes 410 and the fastening holes 120 to secure the side frame 400 to the back of the back panel 100. The number and position of the via holes 410 correspond to the number and position of the fastening holes 120 on the side frame 400.

[0086] In some embodiments, the outer side of the side frame 400 is provided with a mounting hole 420 for accommodating the light guide. The mounting hole 420 extends vertically, and the light guide extends vertically in parallel. This allows the light guide to be positioned longer within the mounting hole, leaving sufficient surface area for emitting a richer light effect.

[0087] Figure 10 It is a structural schematic diagram of the light guide of the utility model from one viewing angle. Figure 11 It is a structural schematic diagram of the light guide of the utility model from another perspective.

[0088] See Figures 6 to 10 The mounting hole includes a restricted area 421 and an open area 422, arranged sequentially in a first direction, with the first direction extending from the center of the display device toward the side frame. The open area is connected to the side of the restricted area facing away from the center of the display device. The spacing between the front and rear side surfaces of the open area gradually increases in the first direction, and the front and rear side walls of the open area in the first direction have a flared structure.

[0089] In some embodiments, the front and rear sidewalls of the open area 420 are arranged in parallel.

[0090] See Figures 3 to 10 The display device further includes a light guide 500, which is fixed to the side frame 400. The light guide 500 is inserted into the mounting hole, and the outer side of the light guide is located in the open area of the side frame. The light guide guides light outward so that the light guide emits light outside the display device.

[0091] In some embodiments, a light source assembly is disposed on the light guide, and light emitted by the light source assembly is conducted through the light guide and transmitted to the outside of the display device.

[0092] The mounting hole is opened on the outer surface of the side frame, and the light guide 500 is at least partially located in the mounting hole 420. The light guide emits light, and the light on the light guide can pass through the mounting hole of the side frame and be projected outside the display device.

[0093] The light guide is fixed on the side frame, and the outer end faces of the light guide in the left and right directions do not exceed the outer end faces of the side frame in the left and right directions. The light guide will not exceed the periphery of the display device. The setting of the light guide 500 will not cause the width of the display device in the left and right directions to increase, and will not affect the size of the display device.

[0094] In some implementations, the plane on which the light emitting surface of the light guide intersects the display surface, such that the light emitting surface emits light toward the rear side of the display device. The display surface is the plane on which the front side of the display panel is located. The plane on which the light emitting surface of the light guide intersects the display surface, such that the light emitting surface emits light toward the rear side of the display device. Light emitted by the light emitting surface can be projected onto the wall behind the display device, thereby creating a light and shadow effect on the rear side of the display device, improving the user experience.

[0095] In other embodiments, the side frames 400 are fixed to the left and right sides of the back of the back panel 100. The left and right outer sides of the side frames 400 are recessed to form mounting holes 420, and the mounting holes 420 are exposed to the left and right sides of the display device. The light emitting surface 510 of the light guide 500 is disposed on the back of the light guide 500; the light emitting surface 510 is located at the edge of the light guide 500; the light emitting surface 510 is tilted forward in the direction toward the outside of the display device, so that the light emitting surface of the light guide 500 can emit light toward the side and rear, thereby forming a light and shadow effect on the rear side of the display device, and can also form light and shadow and glare effects on the wall, thereby improving the user experience.

[0096] In this embodiment, a limiting region 422 is defined on the inner sidewall of the side frame and extends along a first direction through the open region. The light guide 500 is disposed within the limiting region 422 and secured to the side frame 400, such that the light guide 500 is partially located within the limiting region 422 and partially within the open region 421. The provision of the limiting region 422 facilitates the securement and installation of the light guide 500 on the side frame 400.

[0097] In some embodiments, the light guide includes a light guide portion 520 and a fixing portion 530. The fixing portion 530 extends beyond the light guide portion 520 at both ends in the vertical direction and is fixed to the inner sidewall of the side frame. The light guide portion is disposed through the restricted area and the open area. The fixing portion is fixed to the side frame, securing the entire light guide to the side frame. The light guide portion 520 is disposed through the restricted area and the open area to allow the light guide to extend from the inside of the side frame to the outside of the side frame, thereby emitting light outward.

[0098] In some embodiments, a light guide member has a receiving groove 540 on one side facing the interior of the display device; the light source assembly is attached to the side of the interior of the display device and extends into the receiving groove 540. The light source assembly is fixed to the fixing portion of the light guide member to facilitate installation of the light guide member and the light source assembly.

[0099] In some embodiments, the light source assembly is located outside the light guide member, and the light source assembly emits light toward the light incident surface of the light guide member.

[0100] The limiting area 422 extends vertically and is a long hole, so that the limiting area 422 has a preset length in the vertical direction, so that a light guide with a preset length can be installed. The light guide has a fixed length, and the limiting area extends vertically to adapt to the length of the light guide.

[0101] In some embodiments, no limiting area 422 is provided on the side frame 400 , and the light guide 500 is entirely located within the open area 421 .

[0102] In some embodiments of the present application, the light guide 500 has a preset length in the vertical direction, so that the light emitting surface 510 has a preset length, so as to form a better glare effect on the wall behind the display device.

[0103] In some embodiments of the present application, the distance between the front and rear side walls of the open area 421 in the first direction gradually increases, so as to effectively avoid blocking the light from the light guide 500 toward the side and rear.

[0104] In some embodiments, the front and rear side walls of the open area are arranged parallel in the first direction, and the front and rear side walls of the open area do not block the light emitted by the light guide.

[0105] In some embodiments of the present application, a plurality of light-transmitting holes are provided on the light-emitting surface 510 of the light guide 500, and light is emitted from the light-transmitting holes to the outside of the light guide 500, so that the light guide 500 can project different patterns and formations, thereby improving the user experience.

[0106] In some embodiments, the light guide 500 is formed by injection molding, and the surface of the light guide 500 is provided with a coating structure, so that the light guide 500 has a semi-transparent or opaque structure. A light-transmitting hole is opened in the light-emitting layer to emit light through the light-transmitting hole. A light-emitting area is formed at the light-transmitting hole, and a non-light-transmitting area is formed outside the light-transmitting hole.

[0107] In other embodiments, the coating structure on the light guide 500 is a non-light-transmitting area, and the coating structure is removed from the light-emitting layer by laser, engraving, etc. to form a light-transmitting hole. The light-transmitting hole is a blind hole or a through hole.

[0108] In this embodiment, the light guide 500 is formed into a coating structure by vacuum plating after injection molding. In other embodiments, the light guide 500 is formed into a coating structure by other methods, such as spraying.

[0109] In other embodiments, the light guide 500 is made of a light-transmitting material, and the coating structure is a semi-transmitting structure. By providing coatings of different colors, the light guide 500 can be formed in different colors.
