[0031] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. Additionally, it should be noted that for the sake of description, only parts related to the present invention are shown in the accompanying drawings rather than all structures.

[0032] Figure 1 is a schematic diagram of a display screen provided by the prior art. Referring to Figure 1 , there is a long strip-shaped screen lamp L sold on the market and installed above the display 100. This screen lamp L can be used as a desk lamp after the display 100 is turned off; it can also increase the ambient light brightness, reduce the glare of the screen, and improve the user's visual experience when the screen is lit and working. However, currently, displays generally adopt a three-sided (top, left, and right) ultra-narrow bezel design, making it difficult to integrate the traditional screen lamp L; due to the large integration difficulty, the display 100 and the screen lamp L are generally sold separately in the market. On the one hand, users need to purchase the display and the screen lamp L separately, which affects the consistency of the user experience, and at the same time, the additional purchase of peripherals increases the economic burden on users. On the other hand, this discrete design cannot achieve the collaborative optimization of the display and the screen lamp L, restricting the development of multifunctional display applications.

[0033] Based on this, an embodiment of the present invention provides a display panel, which includes a display area and a non-display area. The non-display area is at least located on one side of the display area: a packaging cover plate is located on the light-emitting side of the display panel; the non-display area includes at least one lighting unit and a dimming component, and the dimming component is located on the optical path of the light emitted by the lighting unit; at least part of the light emitted by the lighting unit is adjusted by the dimming component and then directed towards the display area.

[0034] With the above technical solution, in the embodiment of the present invention, an illumination unit and a dimming component are provided in the non-display area of the display panel. After the light emitted by the illumination unit is modulated by the dimming component, at least part of the light is guided to the display area, so as to provide auxiliary ambient illumination when the display panel is working, reduce the glare of the screen, and improve the user's visual experience. At the same time, the illumination unit and the dimming component can be compressed and integrated in the narrow border of the display panel, which can reduce the manufacturing difficulty, reduce the production cost, and meet the needs of multi-functional display applications of the display panel.

[0035] The above is the core idea of the present invention. Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0036] Figure 2 is a schematic structural diagram of a display panel provided by an embodiment of the present invention. Figure 3 is Figure 2 a schematic cross-sectional view of a display panel provided along the AA' direction in Figure 4 is Figure 3 an enlarged schematic view of a dimming component provided in Figure 5 is Figure 2 a schematic cross-sectional view of a display panel provided along the AA' direction in Figure 6 is Figure 5 an enlarged schematic view of another dimming component provided in Figure 4 (a) refers to Figure 4 Figure (a) in Figures 2 - 6 Referring to

[0037] Specifically, referring to Figure 2, in the embodiments of the present invention, there are Liquid Crystal Display (LCD) panels, Organic Light Emitting Diode (OLED) panels, Light Emitting Diode (LED) panels, Micro Light Emitting Diode (Micro LED) panels, Mini Light Emitting Diode (Mini LED) panels, Active-Matrix Organic Light-Emitting Diode (AMOLED) panels, etc. The embodiments of the present invention do not limit the type of the display panel.

[0038] Exemplarily, taking the LCD panel as an example, the display panel 200 further includes a driving substrate TFT, a liquid crystal layer (not shown in the figure), a color filter substrate CF, etc. The liquid crystal layer is located between the driving substrate TFT and the color filter substrate CF, which is not fully shown in the drawings of the embodiments of the present invention. The encapsulation cover plate 10 is disposed on the light-emitting side of the color filter substrate CF, which can block oxygen and moisture, prevent moisture or impurities from entering and diffusing inside the film layers of the display panel 200, and is used to protect the light-emitting surface of the display panel 200. Among them, the encapsulation cover plate 10 can be cover glass or the whole machine housing, which is not limited in the embodiments of the present invention. It should be noted that the multiple film layer structures of the LCD panel work together to achieve the light-emitting display of the display panel. The setting of the film layer structure and the light-emitting principle of the display panel will not be elaborated here.

[0039] Continue to refer to Figure 2 , the display area AA of the display panel 200 can display images normally. The non-display area NA is used to set signal traces, driving chips, etc., such as fanout traces, integrated driver chips (ICs), WOA traces, flexible printed circuit boards (FPCs), etc. At the same time, it can also play a role in protecting the display area AA.

[0040] Among them, the fanout trace refers to the trace and via generated from the pin in a defined direction, which is mainly used to facilitate wiring. The function of the fanout trace is to lead out the signal from the pin and connect it to other signal film layers through vias. The WOA (WebOffset Association) trace is mainly used to connect the FPC and the IC to ensure the correct transmission of signals and data. These traces are usually designed inside the display panel to ensure the stable transmission of signals and the reliability of electrical connections.

[0041] In existing display panels, there are usually large blank areas between FPCs and between ICs. To ensure the thickness uniformity and rubbing uniformity of the display panel, dummy patterns or dummy lines are generally set in these blank areas, which can also be understood as having no functional patterns and functional traces. In an embodiment of the present invention, at least one lighting unit 20 and a dimming component 30 are provided in the blank area of the non-display area NA.

[0042] Among them, the lighting unit 20 can be a lamp bead, a light bar, etc., and its size, quantity, and position can be reasonably adjusted according to the size and position of the blank area in the non-display area NA. For example, LEDs, Micro LEDs, Mini LEDs, etc. that emit white light are not limited in the embodiments of the present invention. The dimming component 30 can be a reflective film, a reflector, etc. with a reflective effect, or an optical prism, etc. with a refraction effect, which is not limited in the embodiments of the present invention.

[0043] Exemplarily, referring to Figure 2 , the lighting unit 20 can be provided on the driving substrate TFT or the color filter substrate CF of the non-display area NA of the LCD display panel. It should be noted that the light-emitting direction of the lighting unit 20 is the same as that of the display area AA. The dimming component 30 is provided on the optical path of the illumination light S emitted by the lighting unit 20.

[0044] In terms of the display effect, when the display area AA emits light, the dimming component 30 reflects / refracts and modulates the illumination light S emitted by the lighting unit 20, so that its propagation direction is directed to the display area AA, enhancing the ambient light illumination of the display area AA, optimizing the screen-to-environment brightness ratio, effectively suppressing the screen stroboscopic perception, reducing the screen glare, improving the color recognition accuracy rate, and finally enhancing the user's visual experience.

[0045] In terms of structure, the lighting unit 20 can use small-sized light-emitting devices such as lamp beads and light bars. In the present invention, the lighting unit 20 and the dimming component 30 are compressed and integrated in the blank area of the non-display area NA, which can keep the original film layer structure of the display panel 200 unchanged, be compatible with the manufacturing process of the existing display panel 200, be beneficial to reducing the preparation difficulty and production cost, and ultimately be beneficial to reducing the user's usage cost.

[0046] In terms of light emission control, the light emission display of the display panel 200 and the light emission of the lighting unit 20 can be independently controlled. In some applications, the display panel 200 is preset to emit light for display, and the lighting unit 20 is synchronously lit. In some applications, after the display panel 200 is preset to emit light for display for a first period of time, the lighting unit 20 is lit. In some applications, the display panel 200 is preset to emit light for display, and the lighting unit 20 is lit at a predetermined moment, etc. Embodiments of the present invention can be flexibly set according to display effects, display time, etc., to achieve the collaborative work of the display panel 200 and the lighting unit 20, and no limitation is made here.

[0047] In summary, in the embodiments of the invention, by arranging a lighting unit and a dimming component in the non-display area of the display panel, when the display panel is lit and working, the light emitted by the lighting unit is modulated by the dimming component and at least part of it is guided to the display area, so as to provide auxiliary ambient lighting when the display panel is working, reduce the glare of the screen, and improve the user's visual experience. At the same time, the lighting unit and the dimming component can be compressed and integrated in the narrow border of the display panel, which can reduce the manufacturing difficulty, reduce the production cost, and meet the needs of the multi-functional display application of the display panel.

[0048] Based on the above embodiments, continue to refer to Figure 2 and Figure 3 , the dimming component 30 is a part of the surface of the encapsulation cover plate 10 close to the lighting unit 20. The dimming component 30 includes at least one first reflection surface 30a, and the first reflection surface 30a faces the display area AA.

[0049] In some embodiments, referring to Figure 4 (a), multiple first reflection surfaces 30a can be prepared on a part of the surface of the encapsulation cover plate 10 close to the lighting unit 20 through processes such as etching and engraving to form a serrated dimming component 30. This structure does not need to introduce a new film layer structure, and using the existing structure of the encapsulation cover plate 10 can reduce the film layer thickness of the display panel.

[0050] In some embodiments, referring to Figure 4 (b), multiple first reflection surfaces 30a can also be embedded on a part of the surface of the encapsulation cover plate 10 close to the lighting unit 20 to form the dimming component 30. The first reflection surface 30a faces the display area AA and has an acute angle with the illumination light S emitted by the lighting unit 20. In this way, when the lighting unit 20 emits light, the first reflection surface 30a can reflect the illumination light S to the display area AA, thereby increasing the ambient light brightness near the display area AA, reducing the glare of the screen, and improving the user's visual experience.

[0051] Optionally, referring to Figure 4 (a) and Figure 4(b), the dimming component 30 includes a plurality of first reflecting surfaces 30a, and the plurality of first reflecting surfaces 30a are parallel to each other. That is to say, the plurality of first reflecting surfaces 30a maintain the same reflection angle, and the illuminating light S can be reflected to the same direction and irradiated to the display area AA, thereby directionally increasing the ambient light brightness near the display area AA and improving the illumination effect. For example, in combination with Figure 3 and Figure 4 , by setting the reflection angles of the plurality of first reflecting surfaces 30a to be the same, only the display area AA is illuminated within the irradiation angle range of 0 to 35° or only a part of the display area AA is illuminated, achieving the effect of area illumination. Among them, the distance between two adjacent first reflecting surfaces 30a can be reasonably adjusted according to the reflection effect, which is not limited here.

[0052] It should be noted that the thickness of the dimming component 30 along the Figure 3 Z direction in is less than or equal to the thickness of the encapsulation cover plate 10, so as to ensure the structural stability of the encapsulation cover plate 10 and avoid risks such as cracking and breaking of the encapsulation cover plate 10.

[0053] On the basis of the above embodiments, a high-reflection film can be additionally plated on the first reflecting surface 30a, which can improve the reflection efficiency of the first reflecting surface 30a for the illuminating light S emitted by the illuminating unit 20 and improve the illumination efficiency of the illuminating unit 20. Among them, the reflection efficiency of the high-reflection film > 99%.

[0054] On the basis of the above embodiments, continue to refer to Figure 5 and Figure 6 , the dimming component 30 is located on the surface of the encapsulation cover plate 10 away from the illuminating unit 20. The dimming component 30 includes a reflection structure 32, and the reflection structure 32 includes at least one second reflecting surface 32a. The included angle between the second reflecting surface 32a and the encapsulation cover plate 10 is an acute angle, and the second reflecting surface 32a faces the display area AA. In the embodiments of the present invention, the dimming component 30 can also be arranged on the surface of the encapsulation cover plate 10 away from the illuminating unit 20. The dimming component 30 is a reflection structure 32 with a reflection function, and the included angle between the second reflecting surface 32a of the reflection structure 32 and the encapsulation cover plate 10 is an acute angle to ensure that the reflected light is directed towards the display area AA. In some embodiments, the reflection structure 32 and the encapsulation cover plate 10 are integrally formed. In some embodiments, the reflection structure 32 and the encapsulation cover plate 10 are adhesively arranged. For example, in the case of a triangular prism structure, in the present invention, the first side surface of the triangular prism structure is attached to the encapsulation cover plate 10, the second side surface is the second reflecting surface 32a, and the third side surface is the light-emitting surface of the reflected light. With the above reflection structure 32 design, the original film layer structure can be kept unchanged, and this structure has the advantages of simple preparation process, easy implementation and low cost.

[0055] Specifically, as Figure 5 and Figure 6As shown, after the illumination light S emitted by the illumination unit 20 passes through the encapsulation cover plate 10, it is efficiently reflected by the second reflection surface 32a (reflection efficiency > 99%) and directionally projected onto the display area AA, so that the ambient light brightness of the display area AA can be significantly improved.

[0056] Based on the above embodiment, as Figure 4 and Figure 6 shown, a highly reflective film (reflectivity > 99%) can be additionally plated on the surface of the second reflection surface 32a. In this way, the reflection efficiency of the illumination light S emitted by the illumination unit 20 is significantly improved, and more light energy is directionally projected onto the display area AA, thereby improving the overall illumination efficiency.

[0057] Figure 7 is Figure 5 an enlarged schematic diagram of another dimming component provided in Figure 7 . Based on the above embodiment, referring to

[0058] In the embodiment of the present invention, a diffusion film 34 can also be provided between the encapsulation cover plate 10 and the reflection structure 32. The diffusion film 34 is located between the second reflection surface 32a and the encapsulation cover plate 10.

[0059] Figure 8 is Figure 5 an enlarged schematic diagram of another dimming component provided in Figure 8, the reflection structure 32 is a prism structure, and the diffusion film 34 is embedded in the reflection structure 32. In the embodiment of the present invention, the reflection structure 32 is designed as a prism structure. The diffusion film 34 can be integrated with the prism structure through an embedded encapsulation process and achieve optical-grade bonding with the encapsulation cover plate 10 to form an integrated optical path system. In this way, gapless optical coupling can be ensured, and the long-term stability of the diffusion film 34 in terms of optical performance and environmental adaptability can be ensured, thereby improving the reliability of the dimming component 30 and playing a role in light homogenization for a long time.

[0060] Among them, this integrated optical design can be prepared by a vacuum lamination process to ensure bubble-free bonding, and the edges of the reflection structure 32 and the encapsulation cover plate 10 are sealed to reduce light leakage and improve the stability of the optical path.

[0061] Figure 9 is Figure 5 An enlarged schematic diagram of another two dimming components provided in Figure 9 , the surface of the diffusion film 34 facing the second reflection surface 32a is a convex surface. In the embodiment of the present invention, the diffusion film 34 is arranged as a convex surface structure with a specific curvature, and the reflection structure 32 is matched and designed as the inner wall of a concave lens. For example, after filling the inner wall of the concave lens with a light diffusion substance and / or other optical materials, the diffusion film 34 is formed. The convex surface structure can increase the scattering surface of the diffusion film 34, thereby improving the uniform light scattering effect on the illumination light S.

[0062] Exemplarily, the light diffusion substance is selected as spherical scattering particles with a particle size of 5 - 20 μm, the refractive index of the optical filling material is a transparent silica gel with n = 1.48 - 1.52, and the interface refractive index gradient Δn < 0.02. With this convex surface structure design of the diffusion film 34, compared with the planar structure, it can be increased by 30% - 50%, greatly improving the scattering angle. The light utilization rate is increased to more than 92% ± 2%, greatly improving the light homogenization efficiency. The UGR value is reduced by 15% - 20%, and the glare suppression effect is significant. The optical performance is greatly improved compared with the planar scattering film.

[0063] Furthermore, the embodiment of the present invention can also optimize the optical path by precisely controlling the refractive index gradient.

[0064] Optionally, referring to Figure 9 (a), the refractive index of the diffusion film 34 is less than the refractive index of the reflection structure 32. In the embodiment of the invention, for example, after filling the inner wall of the concave lens with a light diffusion substance and / or other optical materials with a smaller refractive index, the diffusion film 34 is formed, and the equivalent refractive index is less than the refractive index of the reflection structure 32. Combining Figure 5After the illumination light S passes through the encapsulation cover plate 10, it enters the low-refractive-index reflection structure 32 through the diffusion film 34. During this process, the light is beam-expanded and optimized, and then reflected by the second reflection surface 32a to increase the divergence angle and then evenly irradiate the display area AA. In this way, the optical path optimization adjustment is completed.

[0065] Exemplarily, the equivalent refractive index n1 of the diffusion film 34 is 1.45 - 1.50, such as 1.48 ± 0.02. The refractive index n2 of the reflection structure 32 is 1.55 - 1.60. For example, the PC / PMMA material is selected to satisfy the optical relationship of n1 < n2, and Δn ≥ 0.05. The light utilization rate of the diffusion film 34 reaches more than 93% ± 2% (vs 85% of the traditional structure), greatly improving the light homogenization efficiency. The effective viewing angle is increased to ±75°, greatly improving the viewing angle expansion.

[0066] Optionally, referring to Figure 9 (b), the refractive index of the diffusion film 34 is greater than that of the reflection structure 32. In the embodiments of the invention, the refractive index (n1) of the diffusion film 34 can also be set to be significantly higher than the refractive index (n2) of the reflection structure 32. Specifically, by filling the inner wall of the concave lens with a high-refractive-index light-diffusing material (such as a polymer doped with ZnO nanoparticles, n1 ≥ 1.6) to form the diffusion film 34, its equivalent refractive index is higher than that of the reflection structure 32 (such as PMMA material, n2 ≈ 1.49). Combining Figure 5 After the illumination light S emitted by the illumination unit 20 passes through the encapsulation cover plate 10, the following optical regulation occurs through the diffusion film 34:

[0067] The illumination light S undergoes primary scattering in the diffusion film 34 due to the refractive index difference to achieve wide-angle diffusion; the high-refractive-index reflection structure 32 produces a converging effect on the diffused light, compressing the beam divergence angle to achieve convergence-beam expansion optimization: after being enhanced by reflection from the second reflection surface 32a, the beam passes through the exit surface (which can be a microstructured surface) of the reflection structure 32 while maintaining the converging characteristics for secondary diffusion, and finally irradiates the display area AA with an increased and uniform divergence angle. In this way, the optical path optimization adjustment is completed.

[0068] Figure 10 is Figure 5 an enlarged schematic diagram of another two dimming components provided in Figure 10 . On the basis of the above embodiments, referring to

[0069] In some embodiments, referring to Figure 10(a), the exit surface 32d of the reflection structure 32 is set as a convex surface, and the second reflection surface 32a is set as a flat surface. The illumination light S is diffused by the diffusion film 34, then reflected by the second reflection surface 32a to optimize the divergence angle increase, and then converged by the exit surface 32d and uniformly irradiated onto the display area AA. In this way, the light irradiated onto the display area AA can be increased, the visual transition between the ambient light and the display area AA can be softened, and the overall light homogenization effect can be improved.

[0070] In some embodiments, referring to Figure 10 (b), both the second reflection surface 32a and the exit surface 32d of the reflection structure 32 are set as convex surfaces. The illumination light S is diffused by the diffusion film 34. After the reflection structure 32 reflects and converges the illumination light S, it is converged again by the exit surface 32d and uniformly irradiated onto the display area AA. In this way, the light brightness irradiated onto the display area AA can be increased, and the illumination efficiency can be improved.

[0071] Based on the above embodiments, continue to refer to Figure 10 (b), when the second reflection surface 32a and the exit surface 32d are convex surfaces, the radii of curvature of the two convex surfaces are different; and / or, the morphologies of the two convex surfaces are different. In the embodiments of the present invention, when the second reflection surface 32a and the exit surface 32d adopt different radii of curvature and / or morphology designs, the optical path of the illumination light S can be optimized in segments. The second reflection surface 32a can preferentially control the divergence angle of the illumination light S, and the exit surface 32d can secondarily regulate the spot uniformity. At the same time, the combination of hyperboloids can offset the field curvature introduced by a single surface, and improve the illumination uniformity of the illumination light in the display area AA.

[0072] Figure 11 is Figure 2 Another cross-sectional schematic diagram of a display panel provided along the AA' direction in Figure 12 is Figure 11 An enlarged schematic diagram of a dimming component provided in Figure 11 and Figure 12 , the dimming component 30 further includes a diffusion film 34 and a collimating and beam expanding structure 35. The collimating and beam expanding structure 35 is located on the exit surface 32d of the reflection structure 32. Among them, the exit surface 32d faces the display area AA.

[0073] In the embodiments of the present invention, the collimating and beam expanding structure 35 is integrated on the terminal exit surface 32d of the reflection structure 32, bonded to the reflection structure 32 through an optical adhesive, and faces the display area AA. Exemplarily, the collimating and beam expanding structure 35 can be composed of a collimating unit and a beam expanding unit ( Figure 12It consists of (not shown in the figure). The collimation unit can use a micro prism array to pre - collimate the diffused light, and the beam expansion unit can use a gradient refractive index lens layer to achieve secondary beam expansion of the light. Specifically, the diffusion film 34 is arranged between the encapsulation cover plate 10 and the second reflection surface 32a to achieve the primary diffusion of the incident light. The illumination light S is reflected by the second reflection surface 32a to optimize the increase in the divergence angle. The collimation and beam expansion structure 35 emits the illumination light S after re - beam expansion or converges and then re - expands and emits it, and finally irradiates the entire display area AA with an increased and uniform divergence angle.

[0074] Based on the above - mentioned embodiment, continue to refer to Figure 12 , the collimation and beam expansion structure 35 includes a plano - convex lens; the plane of the plano - convex lens is attached to the exit surface 32d, and the convex surface of the plano - convex lens faces the display area AA. In the embodiment of the present invention, the plane of the plano - convex lens can be seamlessly attached to the exit surface 32d through an optical adhesive layer to reduce the loss at the optical path interface. The convex surface curvature of the plano - convex lens causes the illumination light S to undergo positive convergence, which can compress the beam half - angle, converge the illumination light S towards the display area AA, and the converged light generates uniform divergence in the display area AA, improving the spot uniformity of the light illuminating the display area AA.

[0075] Among them, the curvature of the convex surface of the plano - convex lens can be reasonably adjusted according to the illumination range of the illumination light S to the display area AA, and the embodiment of the present invention does not limit it.

Figure 14 is Figure 13 a cross - sectional schematic diagram of a display panel provided along the BB' direction in Figure 15 is Figure 14 an enlarged schematic diagram of two dimming components provided in Figures 13 - 15 , based on the above - mentioned embodiment, refer to Figure 13 The dimming component 30 is located on the surface of the encapsulation cover plate 10 on the side away from the illumination unit 20. The dimming component 30 includes a reflection structure 32, and the reflection structure 32 includes at least one second reflection surface 32a. The dimming component 30 further includes a rotation axis 33, the rotation axis 33 is fixedly arranged with the reflection structure 32, and the rotation axis 33 extends along the first direction (

[0077] In the embodiment of the invention, the reflection structure 32 can be a plano - convex cylindrical prism. The plane of the plano - convex cylindrical prism is the second reflection surface 32a, and the convex surface faces the encapsulation cover plate 10. The rotation axis 33 can be located inside (refer to Figure 15 (a) shown) or outside (refer to Figure 15(as shown in (b)). Among them, the material selection of the rotation axis 33 needs to meet the high light transmittance characteristics to avoid light absorption. Among them, the display panel 200 further includes a rotation control module, such as a high-precision stepper motor, etc. The high-precision stepper motor is connected to the rotation axis 33, and the rotation axis 33 is driven by the high-precision stepper motor to rotate counterclockwise or clockwise around the first direction ( Figure 13 the X direction in), driving the angle between the second reflection surface 32a of the reflection structure 32 and the cover glass 20 to change. In this way, the irradiation angle of the illumination light S can be adjusted to realize the change of the irradiation area of the display area AA along Figure 13 the Y direction in. Exemplarily, the rotation angle range is between -45° and 45°.

[0078] It should be noted that Figure 16 the gray bidirectional arrow in refers to the counterclockwise or clockwise rotation direction.

[0079] Figure 16 is Figure 14 an enlarged schematic diagram of another two kinds of dimming components provided in. On the basis of the above embodiments, referring to Figure 16 , the dimming component 30 further includes a diffusion film 34. The diffusion film 34 is located between the second reflection surface 32a and the encapsulation cover plate 10. In the embodiment of the present invention, the diffusion film 34 can be fixed on the encapsulation cover plate 10 through the encapsulation layer 34a. The diffusion film 34 can achieve the uniform scattering of the illumination light S emitted by the illumination unit 20 provided in the above embodiments, and play the role of beam expansion optimization for the light, which will not be elaborated here. Among them, the surface of the encapsulation layer 34a is flat, and its material is a high-transmission filter material, such as K9 glass or COP cycloolefin polymer, etc., which can play a role in protecting the diffusion film 34.

[0080] Figure 17 is Figure 14 an enlarged schematic diagram of another two kinds of dimming components provided in. On the basis of the above embodiments, referring to Figure 17 (a), on the basis of the above embodiments, the reflection structure 32 is a plano-convex cylindrical prism. The convex surface of the plano-convex cylindrical prism includes an incident area 32b and an exit area 32c. The diffusion film 34 is located in the incident area 32b of the reflection structure 32. In the embodiment of the present invention, the diffusion film 34 can be fixed on the incident area 32b of the reflection structure 32 through the encapsulation layer 34a. The diffusion film 34 can achieve the uniform scattering of the illumination light S emitted by the illumination unit 20 provided in the above embodiments, and play the role of beam expansion optimization for the light, which will not be elaborated here. The convex surface of the plano-convex cylindrical prism is divided into an incident area 32b and an exit area 32c. The illumination light S diffused by the diffusion film 34 converges to the second reflection surface 32a through the convex incident area 32b, and after the divergence angle is increased and optimized, it is reflected to the convex exit area 32c to expand the beam to the display area AA, thereby improving the illumination uniformity of the illumination light in the display area AA.

[0081] Based on the above embodiments, referring to Figure 17 (b), the dimming component 30 further includes a diffusion film 34. The diffusion film 34 is located on the second reflection surface 32a of the reflection structure 32. In the embodiments of the present invention, the diffusion film 34 can be fixedly attached to the second reflection surface 32a of the reflection structure 32 through the encapsulation layer 34a, and its function is to expand the divergence angle of the reflected light and optimize the light intensity distribution, thereby significantly improving the illumination uniformity and light effect softness of the display area AA.

[0082] Based on the above embodiments, referring to Figures 6 - 17 , a high-reflection film is plated on the second reflection surface 32a of the reflection structure 32. In this way, it helps to enhance the reflection efficiency of the reflected light S emitted by the lighting unit 20, thereby improving the light efficiency utilization rate of the overall lighting unit 20.

[0083] Figure 18 It is a schematic structural diagram of another display panel provided by the embodiments of the present invention. Based on the above embodiments, referring to Figure 18 , the display area AA includes a top side edge Lon, a left side edge LL, and a right side edge LR. A plurality of lighting units 20 are located in the non-display area NA corresponding to the top side edge Lon of the display area AA; the display area AA includes a plurality of light-emitting units 40 arranged in an array; the light-emitting unit 40 includes a red light-emitting unit R, a green light-emitting unit G, and a blue light-emitting unit B arranged along the first direction ( Figure 18 the X direction in

[0084] Among them, the first direction ( Figure 18 the X direction in

[0085] is parallel to the plane where the display area AA is located, and is a direction pointing from the left side edge LL to the right side edge LR of the display area AA.

[0086] In the embodiments of the present invention, the light-emitting unit 40 can adopt any type such as OLED, LED, Micro LED, or Mini LED, which is not limited in the embodiments of the present invention. Conventional display panels usually set lighting devices on the top side edge to achieve a specific visual effect, while the present invention innovatively improves the arrangement of the light-emitting unit 40. By adopting a light-emitting color arrangement opposite to that of ordinary displays, it ensures that the final display effect of the display panel 200 is consistent with the traditional solution. Figure 18 Specifically, when implemented, the width of the top side edge Lon of the display panel 200 is set to be greater than the widths of the left side edge LL, the right side edge LR, and the bottom side edge. The present invention combines the FPC and the IC ( Figure 18(not shown) The non-display area NA integrated on the side of the top surface Lon. Meanwhile, the lighting unit 20 and the dimming component 30 are compactly arranged at the blank position of the non-display area NA on this side. When the display panel 200 works, the light emitted by the lighting unit 20 is modulated by the dimming component 30 and then directionally projected from the side of the top surface Lon to the display area AA. This design effectively alleviates the screen glare problem by increasing the ambient light brightness around the display area, thereby significantly optimizing the user's visual comfort and enhancing the user experience.

[0087] Figure 19 is a schematic structural diagram of another display panel provided by an embodiment of the present invention. On the basis of the above embodiment, with reference to Figure 19 , the non-display area NA includes at least one groove or at least one notch, and the lighting unit 20 is located in the groove N1 or the notch N2. In the embodiment of the present invention, a groove structure is provided in the blank area of the non-display area NA. By embedding the lighting unit 20 in the groove, the film stack thickness in this area can be effectively reduced. For the lighting unit 20 with a relatively large thickness, the lower layer film (such as the glass substrate) at the corresponding position of the groove can be further locally removed to form a glass through hole (TGV) or a glass notch structure, so as to provide sufficient accommodation space for the lighting unit 20. This design scheme can not only ensure the stable integration of the lighting unit 20, but also maintain the flatness of the overall structure of the display panel.
