Description

Technical Field

[0001] This invention relates to the field of display device technology, and in particular to a display panel and a display device using the display panel. Background Technology

[0002] Display devices have many advantages such as thin body, low power consumption, and no radiation, and are widely used in mobile phones, personal digital assistants (PDAs), digital cameras, televisions, computer screens, or laptop screens.

[0003] As display devices become increasingly widespread, people's demands for their aesthetics are also rising. Currently, to make display devices look more beautiful and technologically advanced, people are increasingly pursuing borderless display panels and wanting the non-display area (or light-blocking area) to be as small as possible. However, as the light-blocking area of ​​TV or monitor panels becomes smaller, forcibly covering brand logos is detrimental to logo recognition, and forcibly covering brand logos in the light-blocking area of ​​the panel will disrupt the overall appearance of the panel.

[0004] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Summary of the Invention

[0005] The main objective of this invention is to provide a display panel that facilitates logo identification without compromising the overall appearance of the panel.

[0039] The present invention proposes a display panel 100, which can be understood to be a liquid crystal display panel or an organic light-emitting diode display panel.

[0040] Please refer to the reference. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In this embodiment of the invention, the display panel 100 includes a panel body 1 and a decorative part 2. The panel body 1 has a display area 1a and a non-display area 1b, and the non-display area 1b is disposed around the periphery of the display area 1a. The decorative part 2 is disposed on the panel body 1 and located in the display area 1a.

[0041] In this embodiment, the display panel 100 is a borderless display panel, meaning that the display panel 100 has no border around its perimeter. As people's demands for the aesthetics of the display panel 100 increase, borderless display panels are not only more visually appealing but also more technologically advanced. To increase the display area of ​​the display panel 100 and improve the user's visual experience, the non-display area 1b of the display panel 100 is made smaller and smaller, and is located around the perimeter of the display area 1a.

[0042] As the non-display area 1b becomes smaller and smaller, continuing to forcibly cover the brand logo (i.e., decorative part 2) of the display panel 100 onto the non-display area 1b will make it difficult to manufacture the brand logo of the display panel 100, and will also make the logo less recognizable after it is attached, and will also damage the overall appearance of the display panel 100.

[0043] The display panel 100 of the present invention, by placing the decorative part 2 in the display area 1a of the panel body 1, not only improves the recognizability of the decorative part 2, but also avoids the decorative part 2 from damaging the overall appearance of the panel body 1. Furthermore, by placing the non-display area 1b around the periphery of the display area 1a, that is, by placing the non-display area 1b around the periphery of the display area 1a, it is beneficial to increase the display area 1a of the panel body 1, thereby improving the appearance and technological feel of the display panel 100. At the same time, by placing the decorative part 2 in the display area 1a of the panel body 1 and placing it adjacent to the non-display area 1b, the recognizability of the decorative part 2 is improved without affecting the display effect of the display panel 100.

[0044] It is understood that the decorative part 2 can be a mark or symbol, that is, the decorative part 2 can be a brand mark or symbol of the display panel 100, such as a brand logo, icon, hollow pattern or decorative layer, etc., which is not limited here. In this embodiment, the decorative part 2 can be set on the surface of the panel body 1, which facilitates the processing, setting and attachment of the decorative part 2.

[0045] Of course, in order to maintain the service life of the decorative part 2 and improve the appearance of the display panel 100, the decorative part 2 can also be disposed within the panel body 1. In one embodiment of the present invention, optionally, the decorative part 2 is embedded within the panel body 1 and located in the display area 1a. It is understood that the decorative part 2 can be embedded in the surface of the panel body 1, that is, the decorative part 2 is flush with the surface of the panel body 1; the decorative part 2 can also be embedded inside the panel body 1, for example, the decorative part 2 is disposed between the two side substrates of the panel body 1, etc.

[0046] In one embodiment of the present invention, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the panel body 1 includes a first polarizer 11 and a second polarizer 12 disposed opposite to each other, and a first black matrix 16 disposed between the first polarizer 11 and the second polarizer 12. The first black matrix 16 is disposed corresponding to the non-display area 1b. The decorative part 2 is disposed between the first polarizer 11 and the second polarizer 12 and is spaced apart from the first black matrix 16.

[0047] Understandably, the display panel 100 in this embodiment is a liquid crystal display panel structure. A first black matrix 16 is provided on the panel body 1 corresponding to the non-display area 1b. Since the first black matrix 16 is opaque, the area corresponding to the first black matrix 16 forms the non-display area 1b of the panel body 1; that is, the area of ​​the first black matrix 16 is the same as the area of ​​the non-display area 1b. In this embodiment, by placing the decorative part 2 between the first polarizer 11 and the second polarizer 12, on the one hand, the decorative part 2 is displayed on the display panel 100 through the first polarizer 11 or the second polarizer 12, thereby achieving the identification of the decorative part 2; on the other hand, the decorative part 2 is embedded within the panel body 1, which protects the decorative part 2 and also helps maintain its service life.

[0048] In one embodiment, such as Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the panel body 1 also includes a color filter substrate 13 and an array substrate 14 disposed opposite to each other. The color filter substrate 13 and the array substrate 14 are disposed between a first polarizer 11 and a second polarizer 12. The first polarizer 11 is located on the side of the color filter substrate 13 facing away from the array substrate 14, and the second polarizer 12 is located on the side of the array substrate 14 facing away from the color filter substrate 13. A first black matrix 16 is disposed between the color filter substrate 13 and the array substrate 14.

[0049] In this embodiment, the panel body 1 further includes a liquid crystal layer 15 disposed between the color filter substrate 13 and the array substrate 14. It is understood that the color filter substrate 13 and the array substrate 14 of the panel body 1 are disposed opposite to each other, and the liquid crystal layer 15 is located between the array substrate 14 and the color filter substrate 13. To protect and define the liquid crystal layer 15, the panel body 1 further includes a frame 17 disposed between the array substrate 14 and the color filter substrate 13, the frame 17 surrounding the periphery of the liquid crystal layer.

[0050] Optionally, both the color filter substrate 13 and the array substrate 14 are transparent substrates, such as glass substrates or quartz substrates. In actual manufacturing processes, the array substrate 14 is often designed with a large number of metal traces, that is, multiple scan lines and multiple data lines are formed on the array substrate 14. The multiple scan lines and multiple data lines are insulated and intersected to define multiple pixel units, which are arranged in an array on the array substrate. The pixel units are located within the display area 1a of the display panel 100. Since the metal traces around the array substrate 14 can cause significant reflections, which adversely affect the visual effect of the display panel 100 and the user's viewing experience, in this embodiment, a first black matrix 16 is disposed between the color filter substrate 13 and the array substrate 14, thereby using the first black matrix 16 to block the reflections from the metal traces on the array substrate 14.

[0051] In this embodiment, the surface of the color filter substrate 13 facing away from the array substrate 14 is the light-emitting surface. The first polarizer 11 is located on the side of the color filter substrate 13 facing away from the array substrate 14, that is, the first polarizer 11 covers the light-emitting surface of the color filter substrate 13. The second polarizer 12 is located on the side of the array substrate 14 facing away from the color filter substrate 13, and is used to protect the array substrate 14. That is, the color filter substrate 13 and the array substrate 14 are disposed between the first polarizer 11 and the second polarizer 12. In this way, the first polarizer 11 and the second polarizer 12 can both protect the color filter substrate 13 and the array substrate 14, and also achieve good light transmission to the display panel 100.

[0052] In one embodiment of the present invention, such as Figure 2 As shown, the decorative part 2 is disposed between the first polarizer 11 and the color filter substrate 13. It can be understood that by disposing the decorative part 2 between the light-emitting surface of the color filter substrate 13 and the first polarizer 11, and within the display area 1a, the decorative part 2 can be embedded in the display panel 100, which is beneficial for protecting the decorative part 2. On the other hand, the decorative part 2 effectively improves the recognizability of the markings by reflecting and transmitting light through the light-emitting surface of the color filter substrate 13.

[0053] In one embodiment of the present invention, such as Figure 5As shown, the decorative part 2 is disposed between the second polarizer 12 and the array substrate 14. It can be understood that by disposing the decorative part 2 between the second polarizer 12 and the array substrate 14 and within the display area 1a, not only is the decorative part 2 embedded in the display panel 100, which is beneficial for protecting the decorative part 2, but it also improves the recognizability of the decorative part 2.

[0054] In one embodiment of the present invention, such as Figure 3 and Figure 4 As shown, the decorative part 2 is disposed between the color filter substrate 13 and the array substrate 14, and is spaced apart from the first black matrix 16.

[0055] To achieve both embedded placement and improved signage recognition of the decorative part 2, the decorative part 2 is made of a highly reflective metallic material, such as aluminum, silver, or a highly reflective composite material. To further enhance signage recognition, the light transmittance of the decorative part 2 should reach approximately 50%, meaning its transmittance is greater than or equal to 50%. Simultaneously, the reflectance of the decorative part 2 should be higher than that of the panel body 1; optionally, the reflectance of the decorative part 2 is between 10% and 20%.

[0056] In this embodiment, the decorative part 2 is arranged in a layered manner, that is, the decorative part 2 is a layer of metal film or metal cutout layer disposed between the first polarizer 11 and the color filter substrate 13, or between the second polarizer 12 and the array substrate 14, or between the color filter substrate 13 and the array substrate 14, etc., which is not limited here.

[0057] In this embodiment, the scan lines and data lines on the array substrate 14 are arranged perpendicularly to each other, multiple scan lines are arranged in parallel and spaced apart, and multiple data lines are arranged in parallel and spaced apart. Two adjacent data lines and two adjacent scan lines enclose and define a pixel unit. Optionally, both the scan lines and data lines are formed of a conductor material, such as aluminum alloy or chromium metal.

[0058] In one embodiment of the present invention, such as Figure 3 and Figure 4As shown, the decorative portion 2 is disposed between the color filter substrate 13 and the array substrate 14, and the decorative portion 2 is disposed on the color filter substrate 13 or the array substrate 14. It is understood that the decorative portion 2 is disposed on the side of the color filter substrate 13 facing the array substrate 14, that is, the decorative portion 2 is disposed on the color filter substrate 13. Of course, the decorative portion 2 can also be disposed on the side of the array substrate 14 facing the color filter substrate 13, that is, the decorative portion 2 is disposed on the array substrate 14; this is not limited here. To prevent the metal decorative portion 2 from affecting the scan lines and data lines on the array substrate 14 or the metal traces on the color filter substrate 13, when the decorative portion 2 is disposed between the color filter substrate 13 and the array substrate 14, an insulating layer is provided between the decorative portion 2 and the color filter substrate 13 and / or the array substrate 14 to prevent the decorative portion 2 from conducting with the scan lines and data lines on the array substrate 14 or the metal traces on the color filter substrate 13.

[0059] Understandably, each pixel unit includes a switching element and a pixel electrode. The pixel electrode is electrically connected to the corresponding scan line and data line through the switching element. The optional switching element is a thin-film transistor (TFT), which includes a gate, a source, and a drain. The gate is electrically connected to the corresponding scan line, and the gate is generally formed simultaneously with the scan line using the same material. The source is electrically connected to the corresponding data line, and the drain is electrically connected to the corresponding pixel electrode.

[0060] Typically, the source and drain electrodes are formed simultaneously with the data lines using the same material. Thin-film transistors also include an active layer, which may include a semiconductor layer and a doped semiconductor layer, located below the source and drain electrodes and above the gate. All and part of the doped semiconductor layer between the source and drain electrodes are etched away to form a TFT channel.

[0061] Specifically, when a high level is applied to the gate, the source and drain are connected through the active layer, allowing the image signal voltage from the data line to be supplied to the pixel electrode. To maintain insulation between the conductive structures, an insulating layer covering the scan line and the gate is called a gate insulating layer, and insulating layers covering the data line, active layer, source, and drain are called passivation layers. The pixel electrode is formed on the passivation layer and is connected to the drain through vias in the passivation layer. The pixel electrode can be a semi-transparent electrode or a reflective electrode. When the pixel electrode is a semi-transparent electrode, it may include a transparent conductive layer.

[0062] Understandably, the transparent conductive layer may include at least one of, for example, indium tin oxide (ITO), indium zinc oxide (IZO), zinc oxide (ZnO), indium oxide (In₂O₃), indium gallium oxide (IGO), and zinc aluminum oxide (AZO). In addition to the transparent conductive layer, the pixel electrode may include a semi-transparent reflective layer for improving luminous efficiency. The semi-transparent reflective layer may be a thin layer (e.g., a few nanometers to tens of nanometers thick) and may include at least one of Ag, Mg, Al, Pt, Pd, Au, Ni, Nd, Ir, Cr, Li, Ca, and Yb.

[0063] In one embodiment of the present invention, a first black matrix 16 is disposed on a color filter substrate 13 or an array substrate 14, and the first black matrix 16 surrounds and forms a display area 1a. It is understood that... Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the first black matrix 16 is disposed on the side of the color filter substrate 13 facing the array substrate 14, that is, the first black matrix 16 is disposed on the color filter substrate 13. Of course, the first black matrix 16 can also be disposed on the side of the array substrate 14 facing the color filter substrate 13, that is, the first black matrix 16 is disposed on the array substrate 14, which is not limited here.

[0064] In another embodiment of the invention, such as Figure 6 As shown, the panel body 1 includes a third polarizer 181, a second black matrix 182, a first substrate 183 and an organic light-emitting element layer 184 stacked in sequence. The second black matrix 182 is disposed corresponding to the non-display area 1. The decorative part 2 is disposed between the third polarizer 181 and the first substrate 183 and is spaced apart from the second black matrix 182.

[0065] It is understood that the display panel 100 in this embodiment is an organic light-emitting diode display panel structure. The panel body 1 is provided with a second black matrix 182 corresponding to the non-display area 1b. Since the second black matrix 182 cannot transmit light, the area corresponding to the second black matrix 182 forms the non-display area 1b of the panel body 1. That is, the area of ​​the second black matrix 182 is the same as the area of ​​the non-display area 1b.

[0066] In this embodiment, by placing the decorative part 2 between the third polarizer 181 and the first substrate 183, the decorative part 2 is displayed on the display panel 100 through the third polarizer 181, thereby achieving the identification of the decorative part 2; on the other hand, the decorative part 2 is embedded in the panel body 1, which not only protects the decorative part 2, but also helps to maintain the service life of the decorative part 2.

[0067] Understandably, the first substrate 183 is a transparent substrate, such as a glass substrate or a quartz substrate. The first substrate 183 can also be a color filter substrate or an array substrate, and there is no limitation here. The surface of the first substrate 183 facing away from the organic light-emitting element layer 184 is the light-emitting surface, and the third polarizer 181 is located on the side of the first substrate 183 facing away from the organic light-emitting element layer 184, that is, the third polarizer 181 covers the light-emitting surface of the first substrate 183.

[0068] In this embodiment, the decorative part 2 is disposed between the light-emitting surface of the first substrate 183 and the third polarizer 181, and located within the display area 1a. On the one hand, this allows the decorative part 2 to be embedded in the display panel 100, which is beneficial for protecting the decorative part 2. On the other hand, the decorative part 2 effectively improves the recognizability of the mark by reflecting and transmitting light through the light-emitting surface of the first substrate 183.

[0069] In another embodiment of the invention, such as Figure 6 As shown, the panel body 1 also includes an encapsulation layer 185 and a second substrate 186. The encapsulation layer 185 is disposed on the side of the organic light-emitting element layer 184 facing away from the first substrate 183, and the second substrate 186 is disposed on the side of the encapsulation layer 185 facing away from the organic light-emitting element layer 184.

[0070] Understandably, the encapsulation layer 185 is disposed on the side of the organic light-emitting element layer 184 facing away from the first substrate 183, and is used to encapsulate the organic light-emitting element layer 184. Optionally, the encapsulation layer 185 is a tetrafluoroethylene film encapsulation layer (TFE film encapsulation layer), and the organic light-emitting element layer 184 can be selected as an organic self-emissive layer.

[0071] In this embodiment, the panel body 1 further includes an aluminum foil disposed between the encapsulation layer 185 and the second substrate 186. The second substrate 186 is used to protect the organic light-emitting element layer 184 and the encapsulation layer 185, and also to provide heat dissipation for the panel body 1. Optionally, the second substrate 186 is an aluminum plate. It is understood that in this embodiment, the second substrate 186 and the encapsulation layer 185 are bonded together by an adhesive layer 187.

[0072] In one embodiment of the present invention, the thickness of the decorative portion 2 is 10nm to 20nm. Optionally, the thickness of the decorative portion 2 is 10nm, 11nm, 12nm, 13nm, 14nm, 15nm, 16nm, 17nm, 18nm, 19nm, or 20nm. It is understood that the thickness of the decorative portion 2 cannot be too thick or too thin. If the decorative portion 2 is too thick, it will waste material; furthermore, it will affect the light transmittance of the decorative portion 2, thereby affecting the display effect of the display panel 100. If the decorative portion 2 is too thin, it will affect the recognizability of the markings on the decorative portion 2.

[0073] In one embodiment of the present invention, a display panel 100 includes a panel body 1 and a decorative part 2. The panel body 1 includes a first polarizer 11, a color filter substrate 13, a liquid crystal layer 15, an array substrate 14 and a second polarizer 12 stacked sequentially. The panel body 1 has a display area 1a and a non-display area 1b. The non-display area 1b is disposed around the periphery of the display area 1a. The panel body 1 also includes a first black matrix 16 disposed on the side of the color filter substrate 13 facing the array substrate 14. The first black matrix 16 is disposed corresponding to the non-display area 1b. The decorative part 2 is disposed between the first polarizer 11 and the color filter substrate 13 and is located in the display area 1a.

[0074] It is understood that the display panel 100 in this embodiment is a liquid crystal display panel structure. By embedding the decorative part 2 into the panel body 1, that is, by setting it between the first polarizer 11 and the color filter substrate 13, it is beneficial to protect the decorative part 2 and improve the appearance of the display panel 100. On the other hand, it is also beneficial to improve the recognizability of the decorative part 2. At the same time, setting the decorative part 2 in the display area 1a effectively avoids the decorative part 2 from damaging the overall appearance of the panel body 1.

[0075] Optionally, the decorative part 2 serves as a brand logo or identifier for the display panel 100. In this embodiment, the decorative part 2 is deposited on the light-emitting surface of the color filter substrate 13, that is, the surface of the color filter substrate 13 facing the first polarizer 11, so that a metal layer is formed on the light-emitting surface of the color filter substrate 13. By adjusting the material and thickness of the metal layer of the decorative part 2, the light transmittance and reflectance ratio of the decorative part 2 can be controlled, so that the metal layer of the decorative part 2 has a higher light reflectance than other areas of the panel body 1 without the metal layer of the decorative part 2, thereby achieving the effect of logo identification. When the display panel 100 is displayed, the area with the metal layer of the decorative part 2 has a lower light transmittance than the area without the metal layer of the decorative part 2, thereby giving the decorative part 2 a watermark-like display effect.

[0076] This invention embeds the brand logo of the decorative part 2 within the display area 1a of the panel body 1 (i.e., the pixel area of ​​the display panel 100), effectively maintaining the overall appearance of the display panel 100. Furthermore, the simplified appearance highlights the display panel 100's greater sense of style and trendiness, without increasing the width of the non-display area 1b (i.e., the light-shielding area of ​​the display panel 100) or the size of the derived structures of the display panel 100 to maintain the size of the logo on the decorative part 2. This invention's embedded logo on the decorative part 2 effectively saves on the cost of adhesive-backed logos.

[0077] The present invention also proposes a display device, including the display panel 100 described above.
