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 unique advantages such as flexible fabrication, low driving voltage, and low power consumption, it offers broad application prospects in flat-panel displays, novel lighting, wearable devices, and smart electronic product development, making it one of the hottest research topics. Compared to traditional liquid crystal display (LCD) technology, OLED exhibits many superior performance characteristics, such as high performance and fast response, which significantly surpass 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. OLED, as a self-luminous device, 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 still faces some challenges in practical applications. Especially under ambient light conditions, OLED displays are easily interfered with by external light, causing light reflected from the metal electrodes to significantly interfere with imaging, thereby reducing display contrast, affecting the reading experience, and making the dark state not dark enough.

[0004] To address this issue, existing technologies typically employ the addition of circular polarizers to counteract ambient light reflection. While this approach can effectively mitigate ambient light interference and negatively impact display performance, it also introduces new challenges. A significant portion (approximately 50%) of the light emitted by the OLED organic layer is absorbed by the circular polarizer, significantly reducing light transmittance and light utilization, which in turn impacts 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 addressed in the current development of OLED technology.

[0021] In one possible embodiment, when no voltage is applied to the first electrode layer and the second electrode layer, the focusing portion has a first curvature; when a voltage is applied to the first electrode layer and the second electrode layer, the focusing portion has a second curvature, and the first curvature is greater than the second curvature.

[0022] In a possible implementation, the hydrophobic structure layer includes a hydrophobic portion and a plurality of isolation portions, and the hydrophobic portion is sandwiched between the second electrode layer and the focusing structure layer;

[0041] First embodiment

[0042] like Figure 1-Figure 4 As shown, this embodiment provides a display panel 1 suitable for use in an OLED display and 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 light utilization in the display panel 1, and improve the display performance of the display panel 1.

[0043] The display panel 1 includes a light emitting functional layer 11 and a pixel definition layer 12. The pixel definition layer 12 is formed on the light emitting functional layer 11. The pixel definition layer 12 includes a plurality of pixel openings 121. The plurality of pixel openings 121 are arranged in an array, for example.

[0044] The light-emitting functional layer 11 provides the display light required by the display panel 1. The light-emitting functional layer 11 includes, for example, a plurality of light-emitting units 111. The light-emitting units 111 are correspondingly arranged in the pixel openings 121, so that the pixel definition layer 12 can support or separate the light-emitting units 111, ensuring that the display light can be emitted in a predetermined manner, avoiding mutual interference between adjacent light-emitting units 111, affecting the normal display of the display panel 1, and thus 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, for example, red light-emitting units, green light-emitting units, and blue light-emitting units, respectively, to meet the display requirements of the display panel 1. The light-emitting units 111 can be made of, for example, fluorescent materials, phosphorescent materials, and thermally activated delayed fluorescent materials, so that they have better color rendering effects.

[0045] It should be noted that the display panel 1 also includes a driver backplane 13. The pixel definition layer 12 and the light-emitting functional layer 11 can be stacked on the driver backplane 13. The driver backplane 13 is, for example, low-temperature polycrystalline silicon, and includes thin-film transistors. The use of polycrystalline silicon liquid crystal materials can make the thin-film transistors thinner and smaller, with lower power consumption, etc. Alternatively, the driver backplane 13 can also be a semiconductor such as amorphous silicon, single-crystalline silicon, or metal oxide, depending on the actual situation. The driver backplane 13 is electrically connected to the light-emitting functional layer 11 to facilitate the pixel circuit that controls the lighting of the light-emitting unit 111. Each light-emitting unit 111 corresponds to a pixel circuit. By controlling the pixel circuit, the light-emitting unit 111 can be turned on and off, achieving precise control of the display panel 1 and improving the display response speed and energy efficiency. Each pixel circuit includes at least a TFT structure and a capacitor structure. The TFT structure mainly includes a gate layer, an active layer, a source and drain electrode, and a buffer layer and a dielectric layer disposed between the above layers. The specific structure depends on the actual situation and is not specifically limited in this embodiment.

[0046] The display panel 1 in this embodiment further includes a dimming layer 14 and a light-collecting layer 15 to improve the display performance of the display panel 1 .

[0047] The dimming layer 14 includes a plurality of dimming units 141. An array of the plurality of dimming units 141 is disposed within the pixel definition layer 12 and between two adjacent pixel openings 121, thereby avoiding the light-emitting units 111. The dimming units 141 include a reflective portion 1411 and a light-absorbing portion 1412 disposed within the reflective portion 1411. The reflective portion 1411 is configured to reflect display light emitted by the light-emitting units 111 in the display panel 1 or ambient light entering the display panel 1 from the outside, thereby enhancing the utilization of the display light and reducing interference from ambient light on the display light. For example, the light-absorbing portion 1412 is configured to absorb ambient light entering the display panel 1 from the outside, effectively preventing interference from ambient light on the display light and improving the contrast of the display.

[0048] It should be noted that the dimming layer 14 further includes an encapsulation layer 142 , which is made of a transparent material to ensure that light can penetrate normally without causing significant light loss or color deviation due to the presence of the encapsulation layer 142 , thereby ensuring the light transmittance and color reproduction of the display panel 1 .

[0049] The encapsulation layer 142 is meticulously placed between the multiple dimming units 141, flattening the surface of the dimming layer 14 and enhancing the overall aesthetics and visual uniformity of the display panel 1. Furthermore, the encapsulation layer 142 acts as a protective structure, effectively shielding the light-emitting units 111 and dimming units 141 from the intrusion of harmful substances such as moisture and oxygen, thereby protecting them from damage. This protective effect significantly improves the durability and reliability of the display panel 1, extending its service life.

[0050] The filling of the encapsulation layer 142 also strengthens the bonding between the dimming layer 14 and adjacent layers, making the structure of the entire display panel 1 more compact and stable. This improved stability helps reduce the risk of interlayer separation or damage caused by external vibration or impact.

[0051] The light-gathering layer 15 is disposed on a side of the dimming layer 14 away from the pixel definition layer 12 . The light-gathering layer 15 can gather ambient light or display light, thereby changing the path of the light and adjusting the display performance of the display panel 1 .

[0052] Exemplarily, the light-collecting layer 15 can collect and centrally process ambient light to reduce its impact on the display panel 1. For example, when ambient light enters the display panel 1, it is collected by the light-collecting layer 15 and then enters the light-absorbing portion 1412. The ambient light is then processed by the light-absorbing portion 1412, further reducing the interference of the ambient light on the display panel 1 and improving the stability of the display.

[0053] In other examples, the light-collecting layer 15 can also collect the display light emitted by the light-emitting unit 111, thereby increasing light extraction efficiency and improving light utilization. For example, when the display light emitted by the light-emitting unit 111 strikes the reflective portion 1411, it is reflected into the light-collecting layer 15, collected by the light-collecting layer 15, and then emitted from the display panel 1, significantly improving the utilization of the display light and making the display brighter and clearer.

[0054] The display panel 1 of this embodiment achieves effective control of ambient light and optimized utilization of display light through the synergistic effect of the light-emitting functional layer 11, the pixel definition layer 12, the driving backplane 13, the dimming layer 14 and the focusing layer 15, thereby significantly improving the display performance of the display panel 1.

[0055] Second embodiment

[0056] The second embodiment of the present application further 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-gathering layer 15. The structure of the display panel 1 provided in this embodiment is the same as or similar to that provided in the first embodiment, except that: Figure 1-Figure 3As shown, the light absorbing portion 1412 includes a cavity 14121 formed in the reflective portion 1411 and a transparent light absorbing layer 14122 filling the cavity 14121. The transparent light absorbing layer 14122 may be made of a transparent light absorbing material, which efficiently absorbs light without affecting its transmittance (for non-target light absorption in specific directions or angles). The transparent light absorbing layer 14122 is configured to absorb ambient light collected by the light collecting layer 15, thereby preventing the ambient light from affecting the display light.

[0057] The accommodating 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 retained in the reflective portion 1411. This design enables the transparent light absorbing layer 14122 to more effectively absorb ambient light while avoiding the reduction in light absorption effect caused by uneven material distribution.

[0058] The transparent light-absorbing layer 14122 is made of a transparent light-absorbing material, and can absorb the ambient light gathered by the light-collecting layer 15 while maintaining low interference with the display light.

[0059] By absorbing ambient light, transparent light-absorbing layer 14122 significantly reduces interference from ambient light on the display light, thereby improving the display contrast. Because transparent light-absorbing layer 14122 minimally interferes with the display light, it maintains the clarity and color saturation of the displayed image, enhancing the display effect.

[0060] The light absorption effect of the transparent light absorption layer 14122 helps to optimize the distribution and utilization of light in the display panel 1, avoids interference with the display light, and enables the display light to be more concentratedly irradiated to the target area, thereby improving light utilization efficiency.

[0061] The combination of the accommodating cavity 14121 and the transparent light-absorbing layer 14122 in this embodiment, and their synergistic effect with the light-collecting layer 15, together form a highly 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. Furthermore, by optimizing light utilization and reducing interference, the energy efficiency and reliability of the display panel 1 are improved.

[0062] Third embodiment

[0063] The third embodiment of the present application further provides a display panel 1, comprising a light-emitting functional layer 11, a pixel definition layer 12, a driving backplane 13, a dimming layer 14, and a light-gathering layer 15. The structure of the display panel 1 provided in this embodiment is the same as or similar to that provided in the first embodiment, except that: Figure 2-Figure 4As shown, the light absorbing portion 1412 includes a light absorbing channel 14123 formed in the reflective portion 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, the reflective portion 1411.

[0064] When the ambient light collected by the light-collecting layer 15 enters the transparent layer 14124 , the ambient light hits the inner wall of the light-absorbing channel 14123 and is then reflected by the reflective portion 1411 to the pixel definition layer 12 and absorbed by the pixel definition layer 12 .

[0065] Light absorption channel 14123 provides a specific reflection path for ambient light, allowing the light to be effectively absorbed by pixel definition layer 12 after being reflected by reflective portion 1411. Light absorption channel 14123 can be shaped, for example, rectangular or trapezoidal, as long as it can achieve multiple reflections. By designing a specific reflection path and shape, light absorption channel 14123 increases the number of reflections and path length of light within display panel 1, thereby improving the absorption efficiency of ambient light and reducing interference from ambient light on display light.

[0066] The trapezoidal light absorption channel 14123 can reduce the number of unnecessary reflections and the path length, while ensuring that the ambient light is effectively guided to the pixel definition layer 12 .

[0067] Transparent layer 14124 acts as a light guide, allowing ambient light to pass through and guiding it to the inner wall of light absorption channel 14123. This ensures that ambient light accurately reaches the inner wall of light absorption channel 14123, improving light utilization efficiency. Furthermore, transparent layer 14124 also serves as a protective layer for light absorption channel 14123, preventing it from external contamination or damage.

[0068] After being reflected by the reflective portion 1411 from the inner wall of the light absorption channel 14123, the ambient light 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 display contrast. Due to the reduced interference of ambient light, the display image can maintain higher clarity and color saturation, enhancing the display effect. This reflection and absorption mechanism helps optimize the distribution of light within the display panel 1, allowing the display light to be more concentratedly illuminated to the target area, improving absorption efficiency.

[0069] The display panel 1 in this embodiment, through the synergistic effects of the light absorption channels 14123, the transparent layer 14124, the reflective portion 1411, and the pixel definition layer 12, forms a highly efficient ambient light control system. This structure enables the display panel 1 to better cope with complex and changing ambient light conditions, maintaining a stable display quality. Furthermore, by optimizing light utilization and reducing interference, the energy efficiency and reliability of the display panel 1 are improved.

[0070] Fourth embodiment

[0071] The fourth 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 focusing layer 15. The structure of this embodiment is the same or similar to that of the display panel 1 provided in any one of the first to third embodiments thereof, except that the focusing layer 15 includes a carrying substrate 151 and a plurality of focusing lenses 152 arranged in an array, the plurality of focusing lenses 152 are arranged on the carrying substrate 151, and the carrying substrate 151 is connected to the dimming layer 14.

[0072] The supporting substrate 151 is made of a transparent material, such as a glass support plate or a plastic support plate, to ensure smooth light transmission. The supporting substrate 151 is provided with a plurality of grooves 1511, the shape of which matches the shape of the focusing lens 152, so that the focusing lens 152 can be embedded in the corresponding groove 1511 one by one, improving the stability during installation.

[0073] The carrier substrate 151 provides a stable support platform for the focusing lens 152, while the groove 1511 ensures the secure installation of the focusing lens 152. The design of the carrier substrate 151 and the groove 1511 allows the focusing lens 152 to be securely mounted on the display panel 1, preventing it from falling off or shifting. The shape of the groove 1511 matches that of the focusing lens 152, simplifying the manufacturing and assembly process and improving production efficiency.

[0074] A plurality of focusing lenses 152 are arrayed 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 .

[0075] Exemplarily, the focus of the focusing lens 152 is set to fall within the light absorbing portion 1412 of the dimming unit 141, ensuring that ambient light can smoothly enter the light absorbing portion 1412 for processing. For example, after being refracted by the focusing lens 152, the ambient light can smoothly enter the light absorbing portion 1412 for processing. The focusing lens 152 can focus the ambient light so that it is more concentratedly irradiated into the light absorbing portion 1412 of the dimming unit 141. Through the focusing effect, the ambient light can be more effectively absorbed by the light absorbing portion 1412, reducing the loss and waste of light, preventing it from irradiating the light-emitting functional layer 11, reducing the interference of ambient light on the display light, and improving the contrast and clarity of the display.

[0076] After being refracted by the focusing lens 152, ambient light enters the light absorption unit 1412 for processing. Depending on the specific design of the light absorption unit 1412 (such as the light absorption channel 14123 or the transparent light absorption layer 14122 in the above-mentioned embodiment), the light may be reflected, absorbed, or further processed. By effectively absorbing and processing ambient light, its interference with the display light is reduced, improving display stability. This light processing mechanism helps optimize the distribution of light within the display panel 1, allowing the display light to be more concentratedly illuminated on the target area, thereby improving light utilization and display quality.

[0077] The display panel 1 in this embodiment, the supporting substrate 151 in the light-gathering layer 15, the focusing lens 152, the dimming layer 14, the pixel definition layer 12 and other components work together to 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 the ambient light so that it is more concentratedly irradiated into the light absorbing portion 1412 of the 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 absorbing portion 1412, thereby improving the overall utilization of light.

[0078] Fifth embodiment

[0079] The third embodiment of the present application further 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-gathering layer 15. The structure of the display panel 1 provided in this embodiment is the same or similar to that provided in any of the first to third embodiments, except that: Figure 5 、 Figure 6As shown, the focusing 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, which are stacked in sequence. The layers work closely together to achieve efficient focusing and regulation of light.

[0080] The first substrate 153 serves as the support base of the light-collecting layer 15 and is closely connected to the light-adjusting layer 14 to ensure smooth transmission of light. The first substrate 153 is made of a highly transparent material to reduce light loss during transmission.

[0081] The first electrode layer 154 and the second electrode layer 157 are located on the upper and lower sides of the focusing structure layer 155, respectively, to achieve electric field control. One of the first electrode layer 154 and the second electrode layer 157 is the anode layer, and the other is the cathode layer. The specific configuration needs to be flexibly adjusted according to the actual application scenario and performance requirements.

[0082] The focusing structure layer 155 includes a plurality of focusing portions 1551 arranged in an array. The focal length of each focusing portion 1551 is adjusted by varying the voltage between the first electrode layer 154 and the second electrode layer 157. For example, by varying the voltage difference between the first electrode layer 154 and the second electrode layer 157, the focal length of each focusing portion 1551 in the focusing structure layer 155 can be precisely controlled, thereby achieving dynamic focusing and control of light.

[0083] In this embodiment, the focusing structure layer 155 includes a plurality of focusing sections 1551 arranged in an array. Each focusing section 1551 independently responds to electric field control, enabling flexible adjustment of focal length. This design enables the light-collecting layer 15 to dynamically optimize the focusing effect of light according to varying ambient lighting conditions and display requirements, thereby improving display clarity and contrast.

[0084] For example, the focusing structure layer 155 is an electrowetting structure with adjustable focal length. The focusing structure layer 155 includes a filling layer 1552, which includes a transparent polar solution and a transparent non-polar solution. When the filling layer 1552 contacts the hydrophobic structure layer 156, it can form multiple focusing droplets of a predetermined shape, each of which is configured as a focusing portion 1551. The predetermined-shaped focusing droplets are, for example, a zoom lens composed of tiny droplets to facilitate focusing light. The shape and size of these focusing droplets can be precisely adjusted through subsequent electric field control.

[0085] By changing the voltage of the first electrode layer 154 and the second electrode layer 157 , the shape of the focused droplet is adjusted, thereby adjusting the focal length of each focusing portion 1551 .

[0086] For example, when no voltage is applied to the first electrode layer 154 and the second electrode layer 157, the focusing portion 1551 has a first curvature, and when a voltage is applied to the first electrode layer 154 and the second electrode layer 157, the focusing portion 1551 has a second curvature, and the first curvature is greater than the second curvature.

[0087] That is, when no voltage is applied to the first electrode layer 154 and the second electrode layer 157, the initial contact angle between the focusing droplet and the hydrophobic structure layer 156 is large due to surface tension, and the liquid surface curvature is large. When parallel light passes through the focusing droplet, it will be refracted and converged to a point. In this case, the focal length is relatively long.

[0088] When voltage is applied to the first electrode layer 154 and the second electrode layer 157, the contact angle of the focused droplet will decrease, the curvature of the liquid surface will also decrease, and the focal length will become shorter. By ensuring that the contact angle of the focused droplet does not reach saturation, the curvature of the focused droplet surface can be changed by adjusting the voltage applied to the electrode layer, thereby achieving the purpose of adjusting the focal length of the focusing part 1551.

[0089] In this embodiment, the hydrophobic structural layer 156 is located between the focusing structural layer 155 and the second electrode layer 157. Its surface is hydrophobic, ensuring that the focusing droplets in the filling layer 1552 maintain a stable shape and position. The hydrophobic structural layer 156 also serves as an isolation and protection layer, preventing moisture or other liquids from penetrating into the focusing structural layer 155 and protecting the focusing portion 1551 from damage. This helps maintain the stability of the electric field within the light-concentrating layer 155, ensuring a durable and reliable focusing effect.

[0090] Exemplarily, the hydrophobic structure layer 156 includes a hydrophobic portion 1561 and a plurality of isolation portions 1562 , and the hydrophobic portion 1561 is sandwiched between the second electrode layer 157 and the focusing structure layer 155 .

[0091] A plurality of isolation portions 1562 are connected to the hydrophobic portion 1561 , and one isolation portion 1562 is disposed between two adjacent focusing portions 1551 .

[0092] The isolation portion 1562 not only helps to maintain the stability of the electric field inside the focusing layer 15 and ensure the durability and reliability of the focusing effect, but also effectively prevents mutual interference between the focused droplets and ensures the independence and stability of each focusing portion 1551.

[0093] As the outermost layer of the light-gathering layer 15, the second substrate 158 not only provides the necessary mechanical support for the entire light-gathering 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, ultimately achieving high-quality image display.

[0094] In actual operation, the light-collecting layer 15 and the dimming layer 14 work closely together to achieve high-performance display performance on the display panel 1. The dimming layer 14 initially regulates the light through its dimming units 141, while the light-collecting layer 15 further focuses and optimizes the light, allowing it to more accurately illuminate the target area. Furthermore, the protective effect of the encapsulation layer 142 ensures the stability and reliability of the entire display panel 1 in harsh environments.

[0095] The light-gathering layer 15 dynamically adjusts the focal length of each focusing portion 1551 in the focusing structure layer 155 by precisely controlling 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 light in real time according to different ambient light conditions and display content, effectively reducing light loss and interference, and improving display clarity and contrast. At the same time, the introduction of the hydrophobic structure layer 156 further enhances the durability and stability of the light-gathering 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 diagram in this embodiment is the same as that in the above embodiment. Figure 2 、 Figure 3 The light path schematic diagram shown has the same logic, and you can refer to it. Here, the diagram is not repeated.

[0096] Sixth embodiment

The functional layers are integrated into one through a stacking process to jointly realize the generation, regulation and focusing of light.

[0099] Casing 2, the external support structure of the display device, is connected to display panel 1. It not only provides necessary mechanical protection for display panel 1 but also, through optimized design, enhances overall heat dissipation and electromagnetic shielding. Casing 2 can be made of high-strength aluminum alloy or magnesium alloy, formed through a die-casting process. Its inner surface features mounting grooves that match the shape of display panel 1, ensuring precise positioning and secure fixation.

[0100] It is understood that the housing 2 may also integrate heat dissipation fins and a heat pipe structure to quickly transfer heat generated by the display panel 1 to the outside by optimizing the heat conduction path. Alternatively, the interior of the housing 2 may be coated with a conductive coating to form a continuous electromagnetic shielding layer, effectively suppressing the effects of external electromagnetic interference on the display panel 1 while preventing leakage of internal electromagnetic radiation, thereby ensuring stable operation of the device in complex electromagnetic environments. The specific implementation will be subject to actual circumstances and is not limited here.
