DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiments or implementations may be included in at least one embodiment of the present application. The appearance of such phrases in various places in the specification does not necessarily refer to the same embodiment, nor do they constitute independent or alternative embodiments that are mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] It should be noted that the terms "first," "second," and so on in the specification, claims, and drawings of this application are used to distinguish different objects, rather than to describe a specific order. Furthermore, the terms "including," "having," and any variations thereof are intended to cover non-exclusive inclusions.

[0034] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings.

Therefore, they should not be construed as limitations on the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the orientation of the constituent elements being described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced depending on the circumstances.

[0035] In this specification, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, indirect connections through intermediaries, or internal communication between two components. Those skilled in the art will understand the meaning of these terms in this disclosure based on the specific circumstances.

[0036] With the development of optoelectronic display technology and semiconductor manufacturing technology, thin film transistor liquid crystal display (TFT-LCD) panels have become increasingly mature and have been widely used due to their advantages such as lightness, thinness and portability.

[0037] With the continuous development of display panels, the requirements for display panel optics, panel thickness and panel frame are also constantly increasing. The panel brightness uniformity judgment has been increased from 9 points to 25 points, and the requirements for the uniformity of the overall display brightness of the display panel are becoming more and more stringent. However, in the display panels of the related art, the brightness of the edges of the display panel is lower than that of the center area, and the brightness uniformity of the entire display panel is insufficient. On the one hand, due to the influence of the plastic frame that supports the display screen, the frame of the display panel is too narrow. Under a wide viewing angle, the side wall of the plastic frame can be seen, and the shadow of the line is poor; on the other hand, there is less light available on the high beam side and the corners of the display panel, resulting in a dim overall display brightness.

[0038] Please refer to Figure 1 , Figure 1 Schematic diagram of a cross-sectional structure of a display panel provided in Embodiment 1 of the present application. This application provides a display panel 1 to solve the technical problem that the brightness of the edges of the display panel 1 is lower than that of the center area, and the brightness uniformity of the entire display panel 1 is insufficient.

[0039] The display panel 1 includes a backlight module 101 and a display screen 30 disposed on the backlight module 101. The backlight module 101 includes a back plate 10, a light emitting component 20, and a plastic frame 40. The light emitting component 20 is disposed on the back plate 10. The display screen 30 and the light emitting component 20 are opposite and spaced apart.

[0040] The plastic frame 40 is arranged around the circumference of the light-emitting component 20 and the display screen 30. The extension portion 41 of the plastic frame 40 is arranged between the display screen 30 and the light-emitting component 20 and supports the display screen 30. The extension portion 41 of the plastic frame 40 is provided with a light-transmitting portion 60. After the first light emitted by the light-emitting component 20 passes through the light-transmitting portion 60, the first part of the first light is emitted toward the display screen 30, and the second part of the first light is reflected by the display screen 30 and then emitted toward the light-emitting component 20 through the light-transmitting portion 60.

[0041] The back plate 10 can be used to support the light emitting component 20 and the plastic frame 40 , thereby reducing the probability of the light emitting component 20 being damaged by impact from external objects.

[0042] In this embodiment, the backboard 10 can optionally be made of any one or more of the following materials: polyimide, polyethylene terephthalate (PET), polyethylene naphthalate diformic acid glycol estr (PEN), cycloolefin polymer (COP), polystyrene (PS), polypropylene (PP), and polytetrafluoroethylene (PTFE). In other implementations, the backboard 10 can also be made of glass, ceramics, metal alloys, stainless steel, etc., which is not limited in this application.

[0043] The light emitting component 20 is disposed on the back plate 10 and is used to emit backlight, which forms a display image of the display panel 1 after passing through the display screen 30. The first light is the portion of the backlight that passes through the first light-transmitting portion.

[0044] The plastic frame 40 surrounds the light-emitting assembly 20 and the display screen 30. Specifically, one side of the plastic frame 40 abuts the back panel 10, and the other side supports the display screen 30. The hardness of the plastic frame 40 is less than that of the back panel 10. The plastic frame 40 is disposed between the back panel 10 and the display screen 30 to prevent the display screen 30 from directly abutting against the back panel 10, thereby protecting the display screen 30.

[0045] The material of the plastic frame 40 in this application includes but is not limited to polycarbonate board (PC).

[0046] The extension portion 41 of the plastic frame 40 is arranged between the display screen 30 and the light-emitting component 20 and supports the display screen 30. The plastic frame 40 also includes a main body 42. The main body 42 and the back plate 10 abut against each other to limit the plastic frame 40 so that the plastic frame 40 does not shift relative to the back plate 10.

[0047] Specifically, a buffer member 50 is provided between the extension portion 41 and the display screen 30. The buffer member 50 abuts against the display screen 30. When the display screen 30 is hit, the buffer member 50 can cushion the impact force, thereby reducing the probability of damage to the display screen 30. Furthermore, the buffer member 50 can also be an adhesive member, used to adhere the display screen 30 to the plastic frame 40, thereby preventing the display screen 30 from shifting relative to the plastic frame 40.

[0048] The extension 41 is provided with a light-transmitting portion 60. The display screen 30 has a display area 31 and a non-display area 32. The non-display area 32 is disposed around the display area 31, and the extension 41 corresponds to the non-display area 32. After the first light emitted by the light-emitting component 20 passes through the light-transmitting portion 60, a first portion of the first light is emitted toward the non-display area 32 of the display screen 30 near the display area 31. The portion of light emitted toward the display screen 30 is able to be emitted through the display screen 30, thereby increasing the display brightness at the edge of the display area 31 and improving the uniformity of the display brightness across the entire display area 31.

[0049] The second part of the first light is reflected by the display screen 30 and then emitted toward the light-emitting component 20 through the light-transmitting portion 60. The light-emitting component 20 is provided with a reflector, which can reflect the first light emitted toward the light-emitting component 20 and make it continue to be emitted toward one side of the display screen 30, so that the first light is reused, thereby improving the utilization rate of light in the display panel 1.

[0050] In the display panel 1 provided in the present application, the extension portion 41 of the plastic frame 40 is arranged between the display screen 30 and the light-emitting component 20. After the first light emitted by the light-emitting component 20 passes through the light-transmitting portion 60 of the extension portion 41, the first part of the first light is emitted toward the display screen 30, and the second part of the first light is reflected by the display screen 30 and emitted toward the light-emitting component 20 through the light-transmitting portion 60. The first part of the first light is emitted toward the display screen 30, which can increase the amount of light received by the area of the display screen 30 corresponding to the light-transmitting portion 60, thereby improving the brightness of the edge areas around the display panel 1, thereby improving the uniformity of the overall display brightness of the display panel 1. The second part of the first light is reflected by the display screen 30 and emitted toward the light-emitting component 20 through the light-transmitting portion 60, so that the first light is reused, thereby improving the utilization rate of light in the display panel 1.

[0051] Optionally, the material of the light-transmitting portion 60 includes but is not limited to a transparent polycarbonate board (PC).

[0052] In this embodiment, the plastic frame 40 is made of a black polycarbonate plate (or other dark-colored material with low light transmittance), and the light-transmitting portion 60 is a transparent polycarbonate plate. The light-transmitting portion 60 and the plastic frame 40 are integrally formed. In other words, the plastic frame 40 and the light-transmitting portion 60 can be injection molded together in a single process (double-shot injection molding), without affecting the structural stability and strength of the plastic frame 40 itself. This simplifies the production process of the display panel 1 described in this application and facilitates its batch production.

[0053] The display screen 30 includes a lower polarizer (not shown), a liquid crystal layer (not shown), a filter layer (not shown), and an upper polarizer (not shown). The lower polarizer is a polarizer used to deflect the light emitted by the light-emitting component 20 to form polarized light. The lower polarizer is an analyzer used to verify whether the light after passing through the lower polarizer is polarized. The liquid crystal layer is used to allow the polarized light to pass through and regulate the brightness and other characteristics of the deflected light. The filter layer is used to filter the polarized light, thereby improving the display effect of the display panel 1.

[0054] The second part of the first light is reflected by the lower polarizer back to the light emitting assembly 20 , so that the first light is reused, thereby improving the utilization rate of the light in the display panel 1 .

[0055] In this embodiment, the light-transmitting portion 60 is located at a non-end portion of the extending portion 41 to prevent the edge of the display panel 1 from being too bright.

[0056] Please refer to Figure 2 , Figure 2 2 is a schematic diagram of a cross-sectional structure of a display panel provided in Embodiment 2 of the present application. A plurality of reflective particles 70 are provided in the light-transmitting portion 60 , and the reflective particles 70 can be used to reflect light inside the light-transmitting portion 60 multiple times.

[0057] Specifically, when the first portion of the first light is emitted toward the display screen 30 through the light-transmitting portion 60, the reflective particles 70 within the light-transmitting portion 60 can be used to reflect the first portion of the light multiple times. Firstly, the reflective particles 70 ultimately reflect part of the light toward the display screen 30, diversifying the direction of the light emitted from the light-transmitting portion 60 and increasing the amount of light passing through the lower polarizer. This can increase the illumination area of the first light irradiated onto the display screen 30, further increasing the brightness of the edge areas surrounding the display panel 1. Secondly, the reflective particles 70 reflect part of the light toward the light-emitting component 20, further improving the light utilization efficiency within the display panel 1.

[0058] Optionally, the reflective particles 70 include but are not limited to metal particles or other materials capable of reflecting light.

[0059] Please refer to Figure 3 , Figure 3FIG3 is a schematic diagram of a cross-sectional structure of a display panel provided in Embodiment 3 of the present application. In one embodiment, the light-emitting assembly 20 is an edge-lit light-emitting assembly, comprising a light-emitting element 21 and a light guide 22, with the light-emitting element 21 disposed around the light guide 22. The light-emitting element 21 is configured to emit a second light beam, and the light guide 22 is disposed on a side of the extension portion 41 facing away from the display screen 30. The light guide 22 is configured to direct the second light beam emitted by the light-emitting element 21 toward the side of the display screen 30.

[0060] The light guide member 22 includes a light guide plate 222 and an optical film layer 221 disposed on the light guide plate 222. The optical film layer 221 is disposed on a side of the light guide plate 222 facing the extension portion 42. The optical film layer 221 can be used to process light emitted from the light guide plate 222.

[0061] The light guide plate 222 is made of optical-grade acrylic, which absorbs the second light emitted by the light-emitting element 21. When the second light strikes the various light guide points on the light guide plate 222, the reflected light diffuses at various angles, breaking the reflection conditions and emitting from the light guide plate 222 toward the side of the display screen 30. The light guide plate 222 emits light evenly through the various light guide points of varying density and size, thereby converting the linear light source of the second light into a surface light source.

[0062] The optical film layer 221 includes components such as a diffuser, a brightness enhancement sheet, and a light uniformity sheet that can change the direction of the second light emitted by the light emitting element 21 .

[0063] The distance between the end of the light guide plate 222 near the light emitting element 21 and the extension portion 41 is greater than the distance between the end of the optical film layer 221 near the light emitting element 21 and the extension portion 41, and the distance between the end of the light guide plate 222 near the light emitting element 21 and the main body 42 of the plastic frame 40 is less than the distance between the end of the optical film layer 221 near the light emitting element 21 and the main body 42 of the plastic frame 40. A gap is formed between the end of the light guide plate 222 near the light emitting element 21 and the end of the optical film layer 221 near the light emitting element 21. The extension portion 41 is further provided with a protrusion 414 on the side facing the light guide plate 222. The protrusion 414 is disposed within the gap and abuts the light guide plate 222. The protrusion 414 can be used to fix the position of the light guide plate 222 and can also be used to prevent light emitted from the light emitting element 21 from passing through the light guide plate 222 and directly incident on the optical film material or the display screen 30.

[0064] Optionally, the light emitting component 20 may also be a direct-lit light emitting component, which is not limited in this application.

[0065] The light emitting assembly 20 is an edge-type light emitting assembly 20 , which can reduce the thickness of the light emitting assembly 20 , thereby reducing the thickness of the display panel 1 and improving the lightness and thinness of the display panel 1 .

[0066] Please refer to Figure 2 、 Figure 3 and Figure 4 , Figure 4 This is a schematic diagram of the cross-sectional structure of a plastic frame provided in the first embodiment of the present application. The extension portion 41 includes a first surface 411 facing the display screen 30, a second surface 412 facing the light-emitting assembly 20, and a third surface 413 connected between the first surface 411 and the second surface 412. The light-transmitting portion 60 extends through at least two of the first surface 411, the second surface 412, and the third surface 413.

[0067] In other words, the light-transmitting portion 60 has a light-entering surface 601, which is disposed on the second surface 412 or the third surface 413 and is used to receive light emitted by the light guide 22. Alternatively, the light-entering surface 601 is disposed on the second surface 412 near the light-emitting element 21 and is used to receive light emitted by the light-emitting element 21.

[0068] In one embodiment, see Figure 2 The light-transmitting portion 60 extends through the first surface 411 and the second surface 412, and the light-incident surface 601 is provided on the second surface 412. A portion of the light-emitting element 20 is disposed corresponding to the non-display area 32, and light emitted from the light-emitting element 20 corresponding to the non-display area 32 is emitted to the non-display area 32 through the light-transmitting portion 60, thereby increasing the brightness of the edge of the display area 31 near the non-display area 32.

[0069] In the related art, some display panels with narrow bezels have an operable area that is too close to the edge of the visible area of the plastic frame, making it easy to see the edge of the plastic frame at a wide viewing angle, resulting in a dark shadow on the entire edge, affecting the display brightness and display effect of the display panel.

[0070] Regarding the display problem of the narrow-frame display panel 1, in one embodiment, please refer to Figure 5 , Figure 5It is a schematic diagram of the cross-sectional structure of a display panel provided in the fourth embodiment of the present application. The present application also provides a display panel 1, in which the light-transmitting portion 60 passes through the first surface 411 and the third surface 413. The light-incident surface 601 of the light-transmitting portion 60 is provided on the third surface 413, and the light-emitting component 20 provided under the display area 31 emits the first light upward, and a portion of the first light passes through the third surface 413 of the light-transmitting portion 60 and reflects with the reflective particles 70 in the light-transmitting portion 60 to compensate for the brightness of the third surface 413 of the plastic frame 40, thereby improving the display effect at the edge of the display panel 1. Another portion of the first light enters the light-transmitting portion 60 and is emitted from the first surface 411 to improve the brightness of the edge of the display area 31 close to the non-display area 32.

[0071] In one embodiment, please refer again to Figure 3 The light-emitting assembly 20 is an edge-lit light-emitting assembly. The light-transmitting portion 60 extends through the second surface 412 and the third surface 413, and the light-entering surface 601 is located on the second surface 412 near the light-emitting element 21. The light-entering surface 601 is used to receive the second light emitted by the light-emitting element 21 and the first light emitted by the light-emitting assembly 20. The first light or the second light is emitted from the third surface 413 through the light-transmitting portion 60, thereby increasing the brightness of the third surface 413 of the plastic frame 40.

[0072] It can be understood that in this embodiment, the light-transmitting portion 60 can also pass through the first surface 411, the second surface 412 and the third surface 413, so that the first light or the second light can be emitted from the first surface 411 through the light-transmitting portion 60, thereby improving the brightness of the third surface 413 of the plastic frame 40 and improving the overall uniformity of the display panel 1.

[0073] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the cross-sectional structure of a display panel provided in Embodiment 5 of the present application. In one embodiment, the light-transmitting portion 60 has a first port 61 and a second port 62 disposed opposite each other, with the first port 61 being adjacent to the light-emitting component 20 and the second port 62 being adjacent to the display screen 30, and the first port 61 being larger than the second port 62.

[0074] In other words, the projected area of the first port 61 on the display screen 30 is larger than the projected area of the second port 62 on the display screen 30. In other words, the cross-section of the light-transmitting portion 60 exhibits a convergent shape. This allows more of the first light to enter the light-transmitting portion 60 and be emitted from the light-transmitting portion 60 to the display screen 30, further improving the display brightness of the area of the display panel 1 corresponding to the light-transmitting portion 60 and enhancing the brightness of the peripheral areas of the display panel 1.

[0075] Please refer to Figure 7 , Figure 7 This is a schematic diagram of a cross-sectional structure of a display panel provided in Embodiment 6 of the present application. In one embodiment, the outer wall of the light-transmitting portion 60 is provided with a plurality of concave-convex structures 63, which are used to reflect light. In other words, the outer wall of the light-transmitting portion 60 is provided with a plurality of angular structures.

[0076] Reflective particles 70 are provided on the edges and interior of the concave-convex structure 63 to reflect light, causing light entering the light-transmitting portion 60 to undergo multiple reflections. Firstly, the reflective particles 70 in the concave-convex structure 63 ultimately reflect a portion of the light toward the display screen 30, thereby increasing the area illuminated by the first light beams reaching the display screen 30 and further enhancing the brightness of the peripheral edges of the display panel 1. Secondly, the reflective particles 70 in the concave-convex structure 63 reflect a portion of the light toward the light-emitting component 20, further enhancing the light utilization efficiency within the display panel 1.

[0077] It is understandable that the shape of the light-transmitting portion 60 is not limited to the specific structure in the above-mentioned embodiment. The structures of multiple embodiments can be combined or other structures can be used. This application does not limit this.
