Description

Technical Field

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

[0002] In the current field of information display devices, display panels, such as signage, and specifically logo lights, have become important promotional tools for companies. Their unique visual effects not only create a strong visual impact but also enhance brand recognition. Existing logo lights are generally around 0.5-0.6mm thick. When the logo lights are off, their thickness creates a "double-eyelid" effect due to the staggered height. This creates a noticeable thickness when viewed from the side, diminishing the visual appeal and significantly impacting the user experience. Utility Model Content

[0003] The present application provides a display panel, an information display device and equipment to reduce the visual perception of high and low layers in the display panel due to visual differences in the thickness direction, thereby improving the overall visual perception of the display panel.

[0004] In a first aspect, the present application provides a display panel, comprising a first light-transmitting layer and a second light-transmitting layer stacked together, a coating layer being provided between the first light-transmitting layer and the second light-transmitting layer, the transmittance of the coating layer being less than the transmittance of the first light-transmitting layer and the second light-transmitting layer, and the second light-transmitting layer being the appearance layer of the display panel.

[0005] The display panel of this application decomposes the original single light-transmitting layer into two, with the coating layer positioned between them. Due to the presence of the coating layer, the first light-transmitting layer is obscured by the coating layer, making its thickness essentially invisible. Only the coating layer and the second light-transmitting layer, which serves as the exterior layer, are visible. This effectively reduces the thickness of the display panel, making the entire panel appear thinner and reducing its apparent thickness, thereby improving its overall visual quality.

[0006] Among them, the display board of the present application can be used as an identification, such as a logo light.

[0007] In an optional implementation, the thickness of the first light-transmitting layer is greater than that of the second light-transmitting layer. Since the second light-transmitting layer is an appearance layer, the thickness of the second light-transmitting layer is less than that of the first light-transmitting layer, which can further reduce the perceived thickness and improve the viewing experience of the display panel.

[0008] In an optional implementation, the thickness of the first light-transmitting layer may be 0.35mm-0.5mm. In an optional implementation, the thickness of the second light-transmitting layer may be 0.1mm-0.2mm. The sum of the thickness of the first light-transmitting layer and the thickness of the second light-transmitting layer may be between 0.45-0.6mm. Due to the low transmittance of the coating layer, the first light-transmitting layer will be blocked by the coating layer, thereby making the first light-transmitting layer hidden from a visual perspective. The first light-transmitting layer can provide overall structural strength for the display panel. Therefore, the thickness of the first light-transmitting layer can be set relatively thicker to improve the overall strength of the display panel. The second light-transmitting layer is the appearance layer of the display panel and is not blocked by the coating layer. Visually, the thickness of the display panel seen by the observer can be regarded as the thickness of the second light-transmitting layer. Therefore, the second light-transmitting layer can be set relatively thinner, thereby making the apparent thickness of the display panel thinner.

[0009] In an optional implementation, the coating layer is disposed on the surface of the second light-transmitting layer facing the first light-transmitting layer. This arrangement allows for a stronger bond between the coating layer and the second light-transmitting layer, preventing a gap between the coating layer and the second light-transmitting layer from negatively impacting the visual quality of the display panel.

[0010] In one optional implementation, the coating layer may have a thickness of 0.1-0.3 μm. For example, the coating layer may be a silver layer. By optimizing the thickness of the coating layer, the visual quality of the display panel is not affected, nor is the overall thickness of the display panel affected. It is understood that a silver coating layer can give the display panel a silver appearance.

[0011] In an optional implementation, the first light-transmitting layer may be a PC layer or a PET layer, and the second light-transmitting layer may be a PC layer or a PET layer. PC or PET sheets have high transparency, toughness, and mechanical strength. Using PC or PET to make the first and second transparent layers can provide a better viewing experience for the display panel.

[0012] In a second aspect, the present application provides an information display device comprising a substrate and the display panel of the present application, wherein the first light-transmitting layer is adhered to the surface of the substrate or embedded in a through-slot defined in the substrate. The substrate can be used as a housing, a display stand, or a display board, and its structure, shape, and material can be designed based on the specific application scenario.

[0013] In an optional implementation, the information display device of the present application may further include a light source, and the light source may be provided on a side of the first light-transmitting layer away from the second light-transmitting layer.

[0014] In a third aspect, the present application provides a device comprising the display panel of the present application, wherein the first light-transmitting layer is arranged toward the interior of the device, and the second light-transmitting layer is arranged toward the exterior of the device.

[0015] The device of the present application, because it has the display panel of the present application, can make the appearance of the display panel in the display panel have a better visual effect.

[0016] The equipment of this application may include computers, mobile phones, cabinets, energy storage cabinets, cars, watches and other electronic devices. In addition, it may also include various mechanical equipment, measuring equipment, etc., as long as a display panel is required.

[0017] Among them, the data in the above-mentioned possible implementation methods of the present application, such as the thickness of the first light-transmitting layer, the thickness of the second light-transmitting layer, the thickness of the coating layer, etc., when measured, the values ​​within the engineering measurement error range should be understood to be within the range specified in the present application.

[0027] In order to make the purpose, technical solutions and advantages of this application clearer, this application will be further described in detail below with reference to the accompanying drawings.

[0028] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of this application, the singular expressions "a", "an", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0029] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0030] In the current market, logo lights are used as signage in exhibition booths, display boards, and other display venues. They can also be used on electronic products such as computers, mobile phones, and equipment such as booths and machines. Logo lights have become an important tool for brand promotion. Their unique visual effects not only create a strong visual impact but also enhance brand recognition. Figure 1 The figure is a schematic diagram of the cross-sectional structure of an existing logo light. Figure 2 This is a visual effect diagram of an existing logo light after it is turned off. Figure 1 As shown in the figure, the existing logo light has only one light-transmitting layer 1, and a coating layer 2 is provided on the bottom surface of the light-transmitting layer 1. The light-transmitting layer 1 is the appearance layer of the logo light, and is provided above the coating layer 2, i.e., the side that is observed. In this structure, since the light-transmitting layer 1 is completely provided above the coating layer 2, when being viewed, the appearance has a "double eyelid" effect due to the high and low edge lines formed by the thick side of the light-transmitting layer 1, which in turn affects the user experience. The visual effect is as follows: Figure 2 As shown, the word "HAWA" looks thick and heavy from a visual perspective, and the visual effect is poor.

[0031] To address the above-mentioned issues, an embodiment of the present application provides a display board. The display board of the present application decomposes the structure of one light-transmitting layer in the original logo light into two, and arranges a coating layer between the two light-transmitting layers. Due to the presence of the coating layer, the first light-transmitting layer can be obscured by the coating layer, and its thickness is basically not observable. Only the coating layer and the second light-transmitting layer, which serves as the appearance layer, are observable. In this way, the thickness of the display board is reduced during observation, making the entire display board appear thinner, reducing the apparent thickness of the display board, and thereby improving the overall appearance of the display board.

[0032] The display panel of the present application may be a signboard. The structure of the display panel of the embodiment of the present application is further described below using a signboard as an example.

[0033] Figure 3 This is a schematic diagram of the structure of a display panel according to an embodiment of the present application. Figure 3 As shown, the display board can be used as a display sign and can be used to form specific text or patterns. Figure 3 The display panel 01 includes two light-transmitting layers, which are respectively referred to as a first light-transmitting layer 11 and a second light-transmitting layer 12. The first light-transmitting layer 11 and the second light-transmitting layer 12 are stacked with a coating layer 2 disposed therebetween.

[0034] The first light-transmitting layer 11 can be made of PC film or PET film, ensuring that the display panel 01 has high light transmittance, high flexibility, and processability. The transmittance of the first light-transmitting layer 11 can be greater than or equal to 70%. The thickness of the first light-transmitting layer 11 can be between 0.35 mm and 0.5 mm. The thickness of the first light-transmitting layer 11 should not be too thick, as this increases the overall thickness of the display panel 01 and affects its aesthetics. The thickness of the first light-transmitting layer 11 should also not be too thin, as this reduces the overall structural strength of the display panel 01 and hinders its improvement.

[0035] The second light-transmitting layer 12 serves as the exterior layer of the display panel 01. It can be made of PC film or PET film. Because PC or PET offer high transparency, toughness, and mechanical strength, using PC or PET to create the first and second transparent layers 11 and 12 enhances the visual quality of the display panel 01. The second light-transmitting layer 12 has a transmittance of 70% or greater to improve the display characteristics of the display panel 01.

[0036] The thickness of the second light-transmitting layer 12 can be 0.1 mm to 0.2 mm. Since the second light-transmitting layer 12 serves as the exterior layer, its thickness is less than that of the first light-transmitting layer 11, further reducing the perceived thickness and improving the viewing experience of the display panel 01. The sum of the thicknesses of the first light-transmitting layer 11 and the second light-transmitting layer 12 can be between 0.45 mm and 0.6 mm.

[0037] The coating layer 2 is disposed between the first light-transmitting layer 11 and the second light-transmitting layer 12. The transmittance of the coating layer 2 is less than that of the first light-transmitting layer 11 and the second light-transmitting layer 12. When the display panel 01 is a logo light, a light source can be disposed on the side of the first light-transmitting layer 11 facing away from the second light-transmitting layer 12. The light from the light source penetrates the first light-transmitting layer 11 toward the coating layer 2, and then passes through the coating layer 2 and out of the second light-transmitting layer 12, thereby causing the display panel 01 to display a specific pattern. The transmittance of the coating layer 2 can be between 10% and 25%. The reduction in the transmittance of the coating layer 2 can form a light-dark area at the coating layer 2, thereby causing the display panel 01 to display a color pattern having a certain color. For example, the coating layer 2 in the embodiment of the present application can be a silver layer, which can cause the color of the pattern displayed on the display panel 01 to be silver.

[0038] The thickness of the coating layer 2 is 0.1-0.3 μm. By optimizing the thickness of the coating layer 2, neither the visual effect of the display panel nor the overall thickness of the display panel will be affected.

[0039] Because the second light-transmitting layer 12 serves as the observation surface, light transmitted through the coating layer 2 is observed through the second light-transmitting layer 12. Therefore, defects such as bubbles between the coating layer 2 and the second light-transmitting layer 12 are easily visible. Therefore, when providing the coating layer 2, for example, it can be deposited on the side of the second light-transmitting layer 12 facing the first light-transmitting layer 11 using a vapor deposition process. This arrangement enhances the bond between the coating layer 2 and the second light-transmitting layer 12, preventing gaps between the coating layer 2 and the second light-transmitting layer 12 from negatively impacting the visual appearance of the display panel.

[0040] The coating layer 2 and the second light-transmitting layer 12 can be laminated by lamination, such as hot pressing. During the manufacturing process of the display panel, the coating layer 2 and the second light-transmitting layer 12 can be laminated first, and then the coating layer 2 and the first light-transmitting layer 11 can be laminated.

[0041] The display panel of the embodiment of the present application is Figure 3 Taking the orientation shown as an example, due to the low transmittance of the coating layer 2, in the absence of light, the portion below it, namely the first light-transmitting layer 11, can be blocked by the coating layer 2, thereby visually hiding the first light-transmitting layer 11. The first light-transmitting layer 11 can provide overall structural strength for the display panel. Therefore, the thickness of the first light-transmitting layer 11 can be set relatively thicker to improve the overall strength of the display panel. The second light-transmitting layer 12 is the appearance layer of the display panel and is not blocked by the coating layer 2. Visually, the thickness of the display panel seen by the observer is the thickness of the second light-transmitting layer 12. Therefore, the second light-transmitting layer 12 can be set relatively thinner, thereby making the display panel appear thinner.

[0042] Based on the same technical purpose, the embodiment of the present application further provides an information display device. In addition to the display panel of the present application, the information display device of the embodiment of the present application may also include a substrate, with the first light-transmitting layer attached to the surface of the substrate or embedded in a through-groove defined in the substrate.

[0043] Figure 4 FIG. 1 is a structural diagram of an information display device according to an embodiment. Figure 1 As shown, the first light-transmitting layer 11 is attached to the surface of the substrate 3. When the first light-transmitting layer 11 is attached to the surface of the substrate 3, if the display panel is a logo light, the portion of the substrate 3 attached to the first light-transmitting layer 11 needs to be configured as a light-transmitting panel to allow light to penetrate the first light-transmitting layer 11.

[0044] Figure 5 FIG. 1 is a structural diagram of an information display device according to another embodiment. Figure 5 As shown, the first light-transmitting layer is embedded in the substrate 3 . Figure 6 FIG. 1 is a schematic structural diagram of a substrate according to an embodiment of the present invention. Figure 5 and Figure 6 As shown, when the first light-transmitting layer 11 is embedded in the substrate 3, the substrate 3 needs to be provided with a through-groove 31 that matches the shape of the first light-transmitting layer 11, so that the first light-transmitting layer 11 is embedded in the through-groove 31. In the thickness direction of the first light-transmitting layer 11, the through-groove 31 may be exposed by the first light-transmitting layer 11. For example, the thickness of the first light-transmitting layer 11 may be greater than the thickness of the substrate 3, so that a portion of the first light-transmitting layer 11 protrudes from the surface of the substrate 3, forming a display panel with a three-dimensional effect.

[0045] The first light-transmitting layer 11 can be attached to the surface of the substrate 3 or embedded in the substrate 3 , and the second light-transmitting layer 12 is located on the outer light surface side of the display panel. Figure 7 The diagram of the viewing structure of an information display device according to an embodiment is shown. When a user is viewing the display panel, the second light-transmitting layer 12 faces the viewer. Since the second light-transmitting layer 12 is relatively thin, the overall thickness of the display panel can be visually reduced when viewed, eliminating the double-eyelid viewing effect. For example, a light viewer can see that the word "HAWAHI" is relatively thin. Figure 2 The displayed characters are thin.

[0046] The display panel of the present application can be used as a counter, exhibition stand, etc., and can also be used in various devices such as computers, mobile phones, cabinets, energy storage cabinets, cars, watches, etc. as a product display logo.

[0047] Based on the same technical purpose, an embodiment of the present application provides a device, which includes the display panel of the present application, wherein the first light-transmitting layer is arranged toward the interior of the device, and the second light-transmitting layer is arranged toward the exterior of the device.

[0048] The devices in the embodiments of the present application may include computers, mobile phones, cabinets, energy storage cabinets, cars, watches and other electronic devices. In addition, they may also include various mechanical equipment, measuring equipment, etc., as long as they are equipment that requires identification.

[0049] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
