Description

Technical Field

[0001] The present application relates to the field of display technology, and in particular to a display panel and a display device thereof. Background Art

[0002] Organic Light-Emitting Diode (OLED) technology has made significant progress in recent years. With its unique advantages such as flexible preparation, low driving voltage, and low power consumption, it has shown broad application prospects in the fields of flat panel display, new lighting, wearable devices, and smart electronic product development, and has become one of the most popular research topics. Compared with traditional liquid crystal display (LCD) technology, OLED has many excellent performance characteristics, such as high performance and fast response, which make OLED far superior to LCD in display quality.

[0003] LCD displays rely on backlight modules and upper and lower polarizers to produce effective information display, and their structure is relatively complex. As a self-luminous device, OLED does not require a backlight module and has a simpler structure, so it has always been regarded as an ideal display technology. However, OLED technology is not perfect, and it still faces some challenges in practical applications. Especially under ambient light conditions, OLED displays are easily interfered by external light, causing the light reflected from the metal electrodes to significantly interfere with the imaging, thereby reducing the display contrast, affecting the reading experience, and making the dark state not dark enough.

[0004] In order to deal with this problem, the existing technology usually adopts the method of adding a circular polarizer to resist ambient light reflection. Although this method can effectively resist the interference of ambient light to a certain extent and reduce the negative impact on display, it also brings new problems. Since a considerable portion (about 50%) of the light emitted by the OLED organic layer will be absorbed when passing through the circular polarizer, this leads to a significant reduction in light transmittance and low light utilization, which in turn affects the overall performance and energy efficiency of the OLED display.

[0005] Therefore, how to improve the utilization rate of light emitted by the OLED organic layer while effectively reducing the interference of ambient light on OLED display devices has become a key issue that needs to be urgently solved in the current development of OLED technology. Summary of the invention

[0011] In a possible implementation manner, the focal point of the focusing lens is set to fall within the light absorption portion of the dimming unit.

[0012] In a possible implementation manner, the light condensing layer includes a first substrate, a first electrode layer, a focusing structure layer, a hydrophobic structure layer, a second electrode layer, and a second substrate which are sequentially stacked. The first substrate is connected to the dimming layer; Wherein, the focusing structure layer includes a plurality of focusing portions arranged in an array, and by changing the voltages of the first electrode layer and the second electrode layer, the focal length of each focusing portion is adjusted.

[0013] In a possible implementation, the focusing structure layer includes a filling layer that contacts the hydrophobic structure layer to construct a plurality of focusing droplets in a preset shape, and the focusing droplets are configured as the focusing parts; By changing the voltages of the first electrode layer and the second electrode layer, the shape of the focusing droplets is adjusted, and thus the focal length of each focusing part is adjusted.

[0014] In a possible implementation, when no voltage is applied to the first electrode layer and the second electrode layer, the focusing part has a first curvature, and when a voltage is applied to the first electrode layer and the second electrode layer, the focusing part has a second curvature, and the first curvature is greater than the second curvature.

[0015] In a possible implementation, the hydrophobic structure layer includes a hydrophobic part and a plurality of isolation parts, and the hydrophobic part is clamped between the second electrode layer and the focusing structure layer; A plurality of the isolation parts are connected to the hydrophobic part, and one isolation part is arranged between two adjacent focusing parts.

[0022] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are only a part rather than all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts shall fall within the protection scope of the present application.

[0023] The following disclosure provides many different embodiments or examples for implementing different structures of the present application.

In addition, the present application provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the applicability of other processes and / or the use of other materials.

[0025] First Embodiment As Figures 1-4 shown, this embodiment provides a display panel 1, which is applicable to an OLED display and is installed in a display device, such as a mobile phone, a portable computer, a tablet computer, a television, etc. The display panel 1 in this embodiment can reduce the influence of ambient light, enhance the light utilization rate in the display panel 1, and improve the display performance of the display panel 1.

[0026] The display panel 1 includes a light-emitting functional layer 11 and a pixel definition layer 12, and the pixel definition layer 12 is formed on the light-emitting functional layer 11. The pixel definition layer 12 includes a plurality of pixel apertures 121, and the plurality of pixel apertures 121 are arranged in an array form, for example.

[0027] The light-emitting functional layer 11 provides the display light required by the display panel 1. The light-emitting functional layer 11 includes a plurality of light-emitting units 111, for example. The light-emitting units 111 are correspondingly arranged in the pixel apertures 121, so that the pixel definition layer 12 can support or isolate the light-emitting units 111, ensuring that the display light can be emitted in a predetermined manner, avoiding interference between adjacent light-emitting units 111, affecting the normal display of the display panel 1, and effectively improving the resolution and color performance of the display panel 1, making the display clearer and more vivid. Among them, the light-emitting units 111 include a red light-emitting unit, a green light-emitting unit, and a blue light-emitting unit, respectively, to meet the display requirements of the display panel 1. The light-emitting units 111 can be made of fluorescent materials, phosphorescent materials, thermally activated delayed fluorescence materials, etc., so as to have a good color rendering effect.

[0028] Here, it should be noted that the display panel 1 further includes a driving backplane 13. The pixel definition layer 12 and the light-emitting functional layer 11 can be stacked on the driving backplane 13. The driving backplane 13 is low-temperature polysilicon, for example, and it includes thin-film transistors, for example. Using polysilicon liquid crystal materials, the thin-film transistors can be made thinner, smaller, and have lower power consumption, etc. Alternatively, the driving backplane 13 can also be a semiconductor such as amorphous silicon, single-crystalline silicon, or metal oxide, depending on the actual situation. The driving backplane 13 is electrically connected to the light-emitting functional layer 11 to facilitate the pixel circuit corresponding to controlling the lighting of the light-emitting units 111. Each light-emitting unit 111 corresponds to a pixel circuit. By controlling the pixel circuit, the lighting and extinguishing of the light-emitting units 111 are controlled, realizing the precise control of the display panel 1, and improving the display response speed and energy efficiency. Among them, each pixel circuit includes at least a TFT structure and a capacitor structure. The TFT structure mainly includes a gate layer, an active layer, source and drain electrodes, and buffer layers, dielectric layers, etc. arranged between the above layers, depending on the actual situation. Here, in this embodiment, no specific limitations are made on it.

[0029] The display panel 1 in this embodiment further includes a dimming layer 14 and a light condensing layer 15 to improve the display performance of the display panel 1.

[0030] The dimming layer 14 includes a plurality of dimming units 141. The plurality of dimming units 141 are arranged in an array on the pixel definition layer 12 and are disposed between two adjacent pixel apertures 121, thereby avoiding the light-emitting units 111. Among them, the dimming unit 141 includes a reflection portion 1411 and a light absorption portion 1412 disposed in the reflection portion 1411. The reflection portion 1411 is used to reflect the display light emitted by the light-emitting units 111 in the display panel 1 or the ambient light entering the interior of the display panel 1 from the outside, which can enhance the utilization rate of the display light and at the same time reduce the interference of the ambient light on the display light. For example, the light absorption portion 1412 is used to absorb the ambient light entering the interior of the display panel 1 from the outside, effectively avoiding the interference of the ambient light on the display light and improving the display contrast.

[0031] It should be noted that the above dimming layer 14 further includes a packaging layer 142. The packaging layer 142 is made of a transparent material to ensure that light can penetrate normally without obvious light loss or color shift due to the existence of the packaging layer 142, thereby ensuring the light transmittance and color reproducibility of the display panel 1.

[0032] The packaging layer 142 is carefully filled between the plurality of dimming units 141, achieving the flattening of the surface of the dimming layer 14 and also improving the overall aesthetics and visual uniformity of the display panel 1. And the packaging layer 142 can act as a protective structure, which can effectively isolate the intrusion of harmful substances such as external moisture and oxygen, thereby protecting the light-emitting units 111 and the dimming units 141 from damage. This protective effect significantly improves the durability and reliability of the display panel 1 and extends its service life.

[0033] The filling of the packaging layer 142 also enhances the bonding force between the dimming layer 14 and the adjacent layers, making the structure of the entire display panel 1 more compact and stable. This improvement in stability helps to reduce the risk of interlayer separation or damage caused by external vibration or impact.

[0034] The light condensing layer 15 is disposed on the side of the dimming layer 14 facing away from the pixel definition layer 12. The light condensing layer 15 can condense the ambient light or the display light, thereby changing the path of the above-mentioned light and adjusting the display performance of the display panel 1.

[0035] Exemplarily, the light condensing layer 15 can condense the external ambient light and perform centralized processing on it to reduce the impact on the display panel 1. For example, when the ambient light enters the display panel 1, it is condensed by the light condensing layer 15 and then enters the light absorption portion 1412. The ambient light is processed by the light absorption portion 1412, further reducing the interference of the ambient light on the display panel 1 and improving the display stability.

[0036] In other examples, the light - condensing layer 15 can also condense the display light emitted by the light - emitting unit 111, increasing the light - extraction efficiency and improving the light - utilization rate. For example, when the display light emitted by the light - emitting unit 111 irradiates the reflection part 1411, it is reflected to the light - condensing layer 15, and after being condensed by the light - condensing layer 15, it is emitted from the display panel 1, significantly improving the utilization rate of the display light and making the display brighter and clearer.

[0037] Through the synergistic effect of the light - emitting functional layer 11, the pixel - defining layer 12, the driving backplane 13, the light - dimming layer 14, and the light - condensing layer 15, the display panel 1 of this embodiment realizes the effective control of ambient light and the optimized utilization of display light, thus significantly improving the display performance of the display panel 1.

[0038] Second Embodiment The second embodiment of this application also provides a display panel 1, including a light - emitting functional layer 11, a pixel - defining layer 12, a driving backplane 13, a light - dimming layer 14, and a light - condensing layer 15. The structure of the display panel 1 provided in this embodiment is the same as or similar to that of its first embodiment. The difference is that, as Figures 1-3 shown, the light - absorbing part 1412 includes a receiving cavity 14121 formed in the reflection part 1411 and a transparent light - absorbing layer 14122 filled in the receiving cavity 14121. The transparent light - absorbing layer 14122 is, for example, a transparent light - absorbing material, which can efficiently absorb light without affecting the light - transmissivity (for non - target - absorbed light in a specific direction or angle). The transparent light - absorbing layer 14122 is arranged to absorb the ambient light condensed by the light - condensing layer 15, thereby avoiding the influence of ambient light on the display light.

[0039] The receiving cavity 14121 provides a stable accommodation space for the transparent light - absorbing layer 14122, ensuring that the transparent light - absorbing layer 14122 can be evenly filled and maintained in the reflection part 1411. This design enables the transparent light - absorbing layer 14122 to more effectively absorb ambient light and avoids the reduction of the light - absorption effect caused by uneven material distribution.

[0040] The transparent light - absorbing layer 14122 is made of a transparent light - absorbing material, which can absorb the ambient light condensed by the light - condensing layer 15 while maintaining low interference with the display light.

[0041] By absorbing the ambient light, the transparent light - absorbing layer 14122 significantly reduces the interference of the ambient light on the display light, thereby improving the display contrast. Since the transparent light - absorbing layer 14122 has less interference with the display light, it can maintain the clarity and color saturation of the display screen, enhancing the display effect.

[0042] The light absorption effect of the transparent light-absorbing layer 14122 helps to optimize the distribution and utilization of light in the display panel 1, avoid interfering with the display light, enable the display light to irradiate the target area more concentratedly, and improve the light utilization rate.

[0043] In this embodiment, the combination of the accommodating cavity 14121 and the transparent light-absorbing layer 14122, as well as their synergistic effect with the light condensing layer 15, together constitute an efficient ambient light control system. This structure enables the display panel 1 to better cope with complex and changeable ambient light conditions and maintain a stable display effect. At the same time, by optimizing light utilization and reducing interference, the energy efficiency and reliability of the display panel 1 are also improved.

[0044] Third Embodiment The third embodiment of the present application also provides a display panel 1, including a light-emitting functional layer 11, a pixel definition layer 12, a driving backplane 13, a dimming layer 14, and a light condensing layer 15. The structure of the display panel 1 provided in this embodiment is the same as or similar to that of its first embodiment. The difference is that, as Figures 2-4 shown, the light-absorbing part 1412 includes a light-absorbing channel 14123 formed in the reflecting part 1411 and a transparent layer 14124 filling the light-absorbing channel 14123. The transparent layer 14124 is made of a transparent material, and its function is to allow light to pass through and guide the light to the inner wall of the light-absorbing channel 14123, that is, on the reflecting part 1411.

[0045] When the ambient light aggregated by the light condensing layer 15 enters the transparent layer 14124, the ambient light will irradiate the inner wall of the light-absorbing channel 14123, and then be reflected by the reflecting part 1411 to the pixel definition layer 12, and then be absorbed by the pixel definition layer 12.

[0046] The light-absorbing channel 14123 provides a specific reflection path for the ambient light, so that the light can be effectively absorbed by the pixel definition layer 12 after being reflected by the reflecting part 1411. The light-absorbing channel 14123 is, for example, rectangular, trapezoidal, etc., as long as multiple reflections can be achieved. Through the specific reflection path and shape design, the light-absorbing channel 14123 can increase the number of reflections and the path length of the light in the display panel 1, thereby improving the absorption efficiency of the ambient light and reducing the interference of the ambient light on the display light.

[0047] Among them, the trapezoidal light-absorbing channel 14123 can reduce unnecessary reflection times and path lengths, while ensuring that the ambient light is effectively guided to the pixel definition layer 12.

[0048] The transparent layer 14124 serves as a light guiding layer for ambient light, allowing the ambient light to pass through and guiding it to the inner wall of the light absorption channel 14123. The transparent layer 14124 ensures that the ambient light can accurately irradiate the inner wall of the light absorption channel 14123, improving the utilization efficiency of light. At the same time, the transparent layer 14124 can also serve as a protective layer for the light absorption channel 14123 to prevent it from being contaminated or damaged by the outside world.

[0049] After the ambient light is reflected by the reflection part 1411 on the inner wall of the light absorption channel 14123, it is guided to the pixel definition layer 12 and absorbed. By effectively absorbing the ambient light, the interference of the ambient light on the display light is reduced, thereby improving the contrast of the display. Due to the reduction of the interference of the ambient light, the display screen can maintain higher clarity and color saturation, enhancing the display effect. This reflection and absorption mechanism helps to optimize the distribution of light in the display panel 1, enabling the display light to irradiate the target area more concentratedly and improving the absorption efficiency.

[0050] In the display panel 1 of this embodiment, through the synergistic effect of the light absorption channel 14123, the transparent layer 14124, the reflection part 1411 and the pixel definition layer 12, they jointly constitute an efficient ambient light control system. Among them, this structure enables the display panel 1 to better cope with complex and changeable ambient light conditions and maintain a stable display effect. At the same time, by optimizing light utilization and reducing interference, the energy efficiency and reliability of the display panel 1 are also improved.

[0051] The Fourth Embodiment The fourth embodiment of this application also provides a display panel 1, which includes a light emitting functional layer 11, a pixel definition layer 12, a driving backplane 13, a dimming layer 14 and a light condensing layer 15. The structure of the display panel 1 provided in this embodiment is the same as or similar to that of any one of its first to third embodiments. The difference is that the light condensing layer 15 includes a carrier substrate 151 and a plurality of focusing lenses 152 arranged in an array. The plurality of focusing lenses 152 are arranged on the carrier substrate 151, and the carrier substrate 151 is connected to the dimming layer 14.

[0052] The carrier substrate 151 is made of a transparent material, such as a glass support plate or a plastic support plate, etc., to ensure that light can pass through smoothly. The carrier substrate 151 is provided with a plurality of grooves 1511, and the shape of the grooves 1511 is adapted to the shape of the focusing lenses 152, so that the focusing lenses 152 can be embedded in the corresponding grooves 1511 one by one to improve the stability during installation.

[0053] Among them, the carrier substrate 151 provides a stable support platform for the focusing lens 152, and the groove 1511 ensures the stable installation of the focusing lens 152. The design of the carrier substrate 151 and the groove 1511 enables the focusing lens 152 to be firmly installed on the display panel 1, and it is not easy to fall off or shift. The shape of the groove 1511 is adapted to the shape of the focusing lens 152, which simplifies the manufacturing and assembly processes and improves production efficiency.

[0054] A plurality of focusing lenses 152 are arranged in an array on the carrier substrate 151. The focusing lenses 152 correspond to the dimming units 141 one by one, and the center lines of the focusing lenses 152 coincide with the center lines of the dimming units 141, ensuring that ambient light can enter the corresponding dimming units 141.

[0055] Exemplarily, the focal point of the focusing lens 152 is set to fall within the light absorption portion 1412 of the dimming unit 141, ensuring that ambient light can smoothly enter the light absorption portion 1412 for processing. For example, after being refracted by the focusing lens 152, the ambient light can smoothly enter the light absorption portion 1412 for processing. The focusing lens 152 can focus the ambient light so that it is more concentratedly irradiated onto the light absorption portion 1412 of the dimming unit 141. Through the focusing effect, the ambient light can be more effectively absorbed by the light absorption portion 1412, reducing the loss and waste of light, preventing it from irradiating onto the light-emitting functional layer 11, reducing the interference of ambient light on the display light, and improving the display contrast and clarity.

[0056] After being refracted by the focusing lens 152, the ambient light enters the light absorption portion 1412 for processing. According to the specific design of the light absorption portion 1412 (such as the light absorption channel 14123 or the transparent light absorption layer 14122 in the above embodiments), the light will be reflected, absorbed, or further processed. By effectively absorbing and processing the ambient light, the interference of the ambient light on the display light is reduced, and the display stability is improved. The light processing mechanism helps to optimize the distribution of light within the display panel 1, enabling the display light to be more concentratedly irradiated onto the target area, improving the light utilization rate and the display effect.

[0057] In the display panel 1 of this embodiment, components such as the carrier substrate 151 and the focusing lens 152 in the light condensing layer 15, the light dimming layer 14, and the pixel defining layer 12 cooperate with each other to jointly form an efficient ambient light control system. This structure enables the display panel 1 to better cope with complex and changing ambient light conditions and maintain a stable display effect. At the same time, by optimizing light utilization and reducing interference, the energy efficiency and reliability of the display panel 1 are also improved. The focusing lens 152 can efficiently focus ambient light so that it is more concentratedly irradiated into the light absorption part 1412 of the light dimming unit 141. This focusing effect significantly reduces the loss and waste of light, ensuring that the ambient light can be effectively absorbed by the light absorption part 1412, thereby improving the overall utilization rate of light.

[0058] The fifth embodiment The third embodiment of this application also provides a display panel 1, including a light emitting functional layer 11, a pixel defining layer 12, a driving backplane 13, a light dimming layer 14, and a light condensing layer 15. The structure of the display panel 1 provided in this embodiment is the same as or similar to that of any one of its first to third embodiments. The difference is that, as Figure 5 , Figure 6 shown, the light condensing layer 15 includes a first substrate 153, a first electrode layer 154, a focusing structure layer 155, a hydrophobic structure layer 156, a second electrode layer 157, and a second substrate 158 that are sequentially stacked. Each layer cooperates closely to jointly achieve efficient focusing and regulation of light.

[0059] The first substrate 153 serves as the support basis of the light condensing layer 15. The first substrate 153 is closely connected to the light dimming layer 14 to ensure smooth transmission of light. Its material is selected as a high light transmittance material to reduce light loss during transmission.

[0060] The first electrode layer 154 and the second electrode layer 157 are respectively located on the upper and lower sides of the focusing structure layer 155 to achieve electric field regulation. Among them, one of the first electrode layer 154 and the second electrode layer 157 is an anode layer, and the other is a cathode layer. The specific configuration needs to be flexibly adjusted according to the actual application scenario and performance requirements.

[0061] The focusing structure layer 155 includes a plurality of focusing parts 1551 arranged in an array. By changing the voltages of the first electrode layer 154 and the second electrode layer 157, the focal length of each focusing part 1551 is adjusted. For example, by changing the voltage difference between the first electrode layer 154 and the second electrode layer 157, the focal length of each focusing part 1551 in the focusing structure layer 155 can be precisely regulated to achieve dynamic focusing and regulation of light.

[0062] In the focusing structure layer 155 of this embodiment, a plurality of focusing parts 1551 arranged in an array are provided. Each focusing part 1551 can independently respond to electric field regulation to achieve flexible adjustment of the focal length. This design enables the light condensing layer 15 to dynamically optimize the focusing effect of light according to different ambient light conditions and display requirements, improving the clarity and contrast of the display.

[0063] Exemplarily, the focusing structure layer 155 is, for example, an electro-wetting structure with adjustable focal length. The focusing structure layer 155 includes, for example, a filling layer 1552. The filling layer 1552 includes a transparent polar solution and a transparent non-polar solution, such that when the filling layer 1552 contacts the hydrophobic structure layer 156, a plurality of focusing droplets with a preset shape can be formed. Each focusing droplet is configured as a focusing part 1551. The focusing droplet with a preset shape is, for example, a zoom lens composed of tiny droplets to facilitate light focusing. The shape and size of these focusing droplets can be precisely adjusted through subsequent electric field regulation.

[0064] By changing the voltages of the first electrode layer 154 and the second electrode layer 157, the shape of the focusing droplet is adjusted, and thus the focal length of each focusing part 1551 is regulated.

[0065] For example, when no voltage is applied to the first electrode layer 154 and the second electrode layer 157, the focusing part 1551 has a first curvature. When a voltage is applied to the first electrode layer 154 and the second electrode layer 157, the focusing part 1551 has a second curvature, and the first curvature is greater than the second curvature.

[0066] That is, when no voltage is applied to the first electrode layer 154 and the second electrode layer 157, due to the surface tension, the initial contact angle between the focusing droplet and the hydrophobic structure layer 156 is relatively large, the liquid surface curvature is large, and when parallel light passes through the focusing droplet, it will be refracted and converge at a point. At this time, the focal length is relatively long.

[0067] When a voltage is applied to the first electrode layer 154 and the second electrode layer 157, the contact angle of the focusing droplet will decrease, and the curvature of the liquid surface will also decrease, resulting in a shorter focal length. Under the condition that the contact angle of the focusing droplet does not reach saturation, by adjusting the magnitude of the voltage applied to the electrode layer, the magnitude of the curvature of the liquid surface of the focusing droplet can be changed, thereby achieving the purpose of adjusting the focal length of the focusing part 1551.

[0068] In this embodiment, the hydrophobic structure layer 156 is located between the focusing structure layer 155 and the second electrode layer 157. Its surface has hydrophobicity, which can ensure that the focusing droplets in the filling layer 1552 maintain a stable shape and position. At the same time, the hydrophobic structure layer 156 also plays a role of isolation and protection, preventing moisture or other liquids from penetrating into the focusing structure layer 155, protecting the focusing part 1551 from damage, and thus contributing to maintaining the electric field stability inside the light condensing layer 15 and ensuring the durability and reliability of the focusing effect.

[0069] Exemplarily, the hydrophobic structure layer 156 includes a hydrophobic part 1561 and a plurality of isolation parts 1562. The hydrophobic part 1561 is clamped between the second electrode layer 157 and the focusing structure layer 155.

[0070] The plurality of isolation parts 1562 are connected to the hydrophobic part 1561, and one isolation part 1562 is arranged between two adjacent focusing parts 1551.

[0071] The isolation part 1562 not only helps to maintain the electric field stability inside the light condensing layer 15 and ensure the durability and reliability of the focusing effect, but also can effectively prevent the mutual interference between the focusing droplets, ensuring the independence and stability of each focusing part 1551.

[0072] As the outermost layer of the light condensing layer 15, the second substrate 158 not only provides the necessary mechanical support for the entire light condensing layer 15, but also ensures that the focused light can be smoothly transmitted to the subsequent layer structure of the display panel 1 through its high light transmittance characteristic, ultimately realizing high-quality image display.

[0073] During the actual working process, the light condensing layer 15 and the light regulating layer 14 cooperate closely to jointly achieve high-performance display of the display panel 1. The light regulating layer 14 preliminarily regulates the light through its light regulating unit 141, while the light condensing layer 15 further focuses and optimizes the light, enabling the light to irradiate the target area more precisely. At the same time, the protection of the encapsulation layer 142 also ensures the stability and reliability of the entire display panel 1 in a harsh environment.

[0074] The light condensing layer 15 dynamically adjusts the focal length of each focusing part 1551 in the focusing structure layer 155 by precisely regulating the voltage difference between the first electrode layer 154 and the second electrode layer 157. This dynamic focusing mechanism enables the display panel 1 to optimize the focusing effect of the light in real time according to different ambient light conditions and display contents, effectively reducing the loss and interference of the light, and improving the clarity and contrast of the display. At the same time, the introduction of the hydrophobic structure layer 156 further enhances the durability and stability of the light condensing layer 15, providing a strong guarantee for the long-term reliable operation of the display panel 1. It can be understood that the logic of the light path schematic diagram in this embodiment is the same as that in the above embodiment Figure 2 、 Figure 3The schematic diagrams of the optical paths shown have the same logic. One can refer to the schematic diagrams of the optical paths, and thus, the diagrams will not be provided again here.

[0075] Sixth Embodiment As Figures 1-7 shown, the sixth embodiment of the present application also provides a display device, which combines the design concepts of efficient optical regulation and stable mechanical support, aiming to achieve high-quality image display while ensuring the reliable operation of the device in various environments.

Each functional layer is integrated into one body through a lamination process to jointly achieve the generation, regulation, and focusing of light.

[0077] The housing 2, as the external support structure of the display device, is connected to the display panel 1, not only providing necessary mechanical protection for the display panel 1, but also improving the overall heat dissipation performance and electromagnetic shielding effect through optimized design. Among them, the housing 2 can be made of high-strength aluminum alloy or magnesium alloy materials, etc., and is formed by die-casting process. Its inner surface is designed with an installation groove matching the shape of the display panel 1 to ensure the precise positioning and stable fixation of the panel.

[0078] It can be understood that the housing 2 can also be integrated with heat dissipation fins and heat pipe structures to quickly transfer the heat generated by the display panel 1 to the outside by optimizing the heat conduction path. Or, a conductive coating is applied inside the housing 2 to form a continuous electromagnetic shielding layer, effectively suppressing the influence of external electromagnetic interference on the display panel 1, while preventing internal electromagnetic radiation leakage and ensuring the stable operation of the device in a complex electromagnetic environment. It shall be subject to the actual situation, and no limitation is made here.
