The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, when the phrases "in one embodiment" or "in some embodiments" appear in various places throughout the specification, not all references are to the same embodiment. Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0038] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0040] In the present invention, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] Combination Figure 1The display provided in the present application includes a light source 100, a diffusion film 200 and a first polarizer 300. The diffusion film 200 and the first polarizer 300 are distributed along a first direction Z, the diffusion film 200 is provided with a preset pattern 210, the first polarizer 300 is provided with an opening 310, the projection of the opening 310 in the first direction Z overlaps with the projection of the preset pattern 210 in the first direction Z, and the light source 100 is used to provide light to the diffusion film 200.

[0042] The light emitted by the light source 100 illuminates the diffusion film 200, and the light passes through the preset pattern 210 on the diffusion film 200, illuminates the preset pattern 210 and displays it through the opening 310 of the first polarizer 300, that is, the display of the preset pattern 210 does not rely on additional chips and control circuits, which can significantly reduce energy consumption. At the same time, no complex circuit design and control logic are required to drive the display of the preset pattern 210, which greatly simplifies the design and production process of the display and saves material and manufacturing costs.

[0043] In the comparative example, the combination Figure 2 , the diffusion film 200 is provided with a preset pattern 210, and the first polarizer 300 is not provided with an opening 310 corresponding to the preset pattern 210, but a pen segment area 520 corresponding to the position of the preset pattern 210 is provided on the conductive glass substrate 500 on the liquid crystal display screen. The pen segment area 520 controls the switch through the display driver chip 710, which increases the load of the driver chip 710. According to the area size and complexity of the pen segment area 520, it is necessary to consider the wiring space and driving ability of the display. Some driver chips 710 cannot even drive the pen segment area 520. Even if driven, the power consumption of the display is very large. Moreover, on the same display, when there are a large area of ​​preset pattern 210 and other small area preset patterns 210 at the same time, due to the display unevenness caused by the large resistance difference, the large area of ​​preset pattern 210 is displayed light, and the small area of ​​preset pattern 210 is displayed bright.

[0044] In the display provided in this application, combined with Figure 1 As long as the light source 100 is turned on, the preset pattern 210 is displayed, and the user cannot program to turn on or off the preset pattern 210 when the cluster is running. The preset pattern 210 can be implemented without using any segment area 520, which will not cause overloading of the driver chip 710 or limit the display wiring.

[0045] In some embodiments, in combination Figure 1 , the light source 100 is disposed on a side of the diffusion film 200 away from the first polarizer 300 in the first direction Z. The light source 100 directly irradiates the diffusion film 200 along the first direction Z, and the power consumption is lower.

[0046] Specifically, the light source 100 includes a circuit board and a plurality of lamp beads, and the plurality of lamp beads are installed at intervals on one side surface of the circuit board.

[0047] In some embodiments, in combination Figure 1 The display further includes a conductive glass substrate 400 under the liquid crystal display screen, and the conductive glass substrate 400 under the liquid crystal display screen is located on a side of the first polarizer 300 away from the diffusion film 200 in the first direction Z. The conductive glass substrate 400 under the liquid crystal display screen enhances light transmittance and display effect.

[0048] In one embodiment, in combination Figure 1 The conductive glass substrate 400 under the liquid crystal display screen is integrally formed with a semi-transparent layer 410 or is separately connected with a semi-transparent member, and the projection of the semi-transparent layer 410 or the semi-transparent member in the first direction Z overlaps with the projection of the opening 310 in the first direction Z. The semi-transparent layer 410 or the semi-transparent member can block the opening 310 and the preset pattern 210. When the light source 100 is turned off, there is no color difference between the preset pattern 210 and the surrounding display area, that is, the appearance is integrally black, hiding the opening 310 under the reflected light.

[0049] Specifically, the conductive glass substrate 400 under the liquid crystal display screen is separately connected with a semi-transparent component, and the semi-transparent component and the conductive glass substrate 400 under the liquid crystal display screen are manufactured separately, which reduces the manufacturing difficulty and avoids the entire conductive glass substrate 400 under the liquid crystal display screen and the semi-transparent component being scrapped due to a processing error in the process of integrally forming the conductive glass substrate 400 under the liquid crystal display screen and the semi-transparent component. Optionally, the semi-transparent component is a semi-permeable membrane, a semi-permeable sheet, etc., which is not limited here. Optionally, the semi-transparent component is separately connected to the conductive glass substrate 400 under the liquid crystal display screen by bonding, welding or clamping, etc., which is not limited here.

[0050] Specifically, the conductive glass substrate 400 under the liquid crystal display screen is integrally formed with a semi-transmissive layer 410 .

[0051] Optionally, the semi-transmissive layer 410 is a light-diffusing ink or a light-diffusing paint. The light-diffusing ink or the light-diffusing paint can effectively scatter the light passing through the preset pattern 210, so that the light distribution is more uniform, thereby achieving a uniform display effect. In addition, the light-diffusing ink or the light-diffusing paint has a lower cost, and its thickness and volume are smaller, so that the display can be designed to be thinner and lighter. The light-diffusing ink or the light-diffusing paint can be directly coated on the surface of the conductive glass substrate 400 under the liquid crystal display screen, without the need for additional connection structures or bonding operations, which simplifies the assembly process and improves assembly efficiency.

[0052] Optionally, combined Figure 1, the semi-permeable layer 410 is printed and set on the surface of the conductive glass substrate 400 under the liquid crystal display. Compared with the setting methods such as spraying, electroplating, physical deposition or 3D printing, the semi-permeable layer 410 is directly printed on the surface of the conductive glass substrate 400 under the liquid crystal display, and the material cost is greatly reduced. In addition, the printing setting process is mature and has high precision, which can ensure the uniformity and consistency of the semi-permeable layer 410 on the conductive glass substrate 400 under the liquid crystal display. The printing setting process is simple and fast, which improves production efficiency and reduces processing difficulty. The semi-permeable layer 410 adopts a printing process to achieve close fit on the surface of the conductive glass substrate 400 under the liquid crystal display, which can better play its light scattering and homogenization role and improve the display effect. It can be understood that in other embodiments, the semi-permeable layer 410 is formed integrally with the conductive glass substrate 400 under the liquid crystal display by means of spraying, electroplating, physical deposition or 3D printing, which is not limited here.

[0053] Specifically, combined Figure 1 The semi-transparent layer 410 or the semi-transparent member is located on the surface of one side of the conductive glass substrate 400 under the liquid crystal display screen close to the diffusion film 200. The semi-transparent layer 410 or the semi-transparent member can diffuse the light passing through the preset pattern 210 more directly and effectively. Since the light will undergo reflection, refraction and other processes during the propagation process, arranging the semi-transparent layer 410 or the semi-transparent member at a position close to the diffusion film 200 can reduce the light loss, improve the utilization rate of the light, and ensure that the light is more uniform during the diffusion process, thereby improving the overall uniformity of the display effect. The semi-transparent layer 410 or the semi-transparent member can more effectively control the propagation direction of the light, and through the diffusion of the light, reduce the possibility of the light directly shining on the viewer's eyes and reduce the glare phenomenon. At the same time, since the light is evenly diffused, the shadow caused by the light shining on the object can also be reduced, and the viewing comfort can be improved.

[0054] In one embodiment, in combination Figure 1 , the projection of the semi-transparent layer 410 or the semi-transparent member in the first direction Z covers the projection of the opening 310 in the first direction Z. Since the semi-transparent layer 410 or the semi-transparent member completely covers the opening 310, when light passes through, there will be no bright strip at the edge of the uncovered opening 310, ensuring that the entire preset pattern 210 area has uniform brightness when displayed.

[0055] It can be understood that in other embodiments, the projection of the semi-transparent layer 410 or the semi-transparent member in the first direction Z overlaps with the projection of the opening 310 in the first direction Z, and can overlap the projection of the opening 310 in the first direction Z by 70% to 100%, and the preset pattern 210 can also be displayed.

[0056] In one embodiment, in combination Figure 1, the conductive glass substrate 400 under the LCD screen is connected with a flexible circuit board 720. The flexible circuit board 720 is used to connect to an external main control device to control the voltage and current of the conductive glass substrate 400 under the LCD screen to adjust the display content of the display. The flexible circuit board 720 has the characteristics of bending and folding, so that it can fit closely to the side of the conductive glass substrate 400 under the LCD screen, thereby greatly saving the space inside the display. This layout enables the display to achieve a more compact and thin design while maintaining high performance, meeting the needs of miniaturization and lightweight of electronic products.

[0057] In one embodiment, in combination Figure 1 The conductive glass substrate 400 under the liquid crystal display is connected to a driving chip 710. The driving chip 710 is used to control the display of the contents in the rest of the conductive glass substrate 400 under the liquid crystal display, and the area facing the opening 310 only needs to turn on the light source 100 to display the preset pattern 210, without increasing the load of the driving chip 710, and there is no need to consider the wiring of this area.

[0058] In one embodiment, in combination Figure 1 , the thickness of the semi-transparent layer 410 or the semi-transparent member is 1 μm to 5 μm. When the thickness of the semi-transparent layer 410 is less than 1 μm, the processing is difficult, and the effect of hiding the opening 310 is not strong. When the thickness of the semi-transparent layer 410 is increased to 1 μm to 5 μm, it can maintain a high light transmittance while having poor transmittance to ambient light when the light source 100 is turned off, and can well hide the opening 310. When the thickness of the semi-transparent layer 410 is greater than 5 μm, the transmittance is general, which will cause the brightness of the preset pattern 210 to be improved.

[0059] In one embodiment, in combination Figure 1 , the mesh number of the semi-transparent layer 410 or the semi-transparent member is 350 to 500. Due to the large mesh number (350 to 500 mesh), the semi-transparent layer 410 or the semi-transparent member can effectively and evenly scatter the point light emitted by the light source 100, making the light softer and more uniform, and reducing the problem of poor display effect caused by uneven light. In addition, a higher mesh number also means a smaller sieve size, which can further refine the scattering effect of light and make the display effect more delicate and clear. Although the higher the mesh number, the better the scattering effect of the semi-transparent layer 410 or the semi-transparent member, the cost will also increase accordingly. Therefore, the mesh is limited to less than or equal to 500 mesh, which not only meets the display effect requirements but also has a good cost-effective mesh number.

[0060] In one embodiment, the semi-transmissive layer 410 or the semi-transmissive element has a transmittance of 0.5% to 1.0% to direct ambient light. When sunlight is directly incident, the transmittance is low, which reduces glare and reflection.

[0061] In one embodiment, the semi-transmissive layer 410 or the semi-transmissive member has a transmittance of 1.0% to 1.8% to indirect ambient light. When indoors, the user can identify the position of the preset pattern 210 .

[0062] In some embodiments, in combination Figure 1 The display further includes an upper conductive glass substrate 500 on the LCD screen, which is located on a side of the lower conductive glass substrate 400 on the LCD screen away from the diffusion film 200 in the first direction Z. The lower conductive glass substrate 400 on the LCD screen and the upper conductive glass substrate 500 on the LCD screen cooperate to dynamically display content.

[0063] Specifically, the conductive glass substrate 500 on the liquid crystal display screen is provided with a second conductive layer 530. The second conductive layer 530 is arranged around the blank area 510, but is staggered with the blank area 510.

[0064] In one embodiment, in combination Figure 1 The conductive glass substrate 500 on the liquid crystal display screen is provided with a blank area 510, and the projection of the blank area 510 in the first direction Z overlaps with the projection of the semi-transparent layer 410 or the semi-transparent member in the first direction Z. The blank area 510 does not need to be provided with a circuit structure, does not increase the control load, and is also conducive to unblocking the light passing through the preset pattern 210, optimizing the light transmittance and improving the display effect.

[0065] In one embodiment, the projection of the blank area 510 in the first direction Z covers the projection of the semi-transparent layer 410 or the semi-transparent member in the first direction Z, that is, light can be emitted through the semi-transparent layer 410 or the semi-transparent member through the blank area 510 without being blocked, thereby reducing light loss and light scattering. It can be understood that in other embodiments, the projection of the blank area 510 in the first direction Z overlaps with the projection of the semi-transparent layer 410 or the semi-transparent member in the first direction Z, and can overlap the projection of the semi-transparent layer 410 or the semi-transparent member in the first direction Z by 70% to 100%, and the preset pattern 210 can also be displayed.

[0066] In one embodiment, in combination Figure 1 The display further includes a second polarizer 600, which is located on a side of the upper conductive glass substrate 500 of the liquid crystal display screen away from the lower conductive glass substrate 400 of the liquid crystal display screen in the first direction Z. The second polarizer 600 cooperates with the first polarizer 300 to ensure that the light is correctly polarized.

[0067] In some embodiments, in combination Figure 1, the projection of the opening 310 in the first direction Z covers the projection of the preset pattern 210 in the first direction Z. Since the opening 310 completely covers the preset pattern 210, there will be no missing of the uncovered part of the preset pattern 210 when the light passes through, ensuring that the entire preset pattern 210 is fully displayed.

[0068] It can be understood that in other embodiments, the projection of the opening 310 in the first direction Z overlaps with the projection of the preset pattern 210 in the first direction Z, and can overlap the projection of the preset pattern 210 in the first direction Z by 70% to 100%, and can also roughly display the preset pattern 210.

[0069] In some embodiments, the preset pattern 210 is integrally formed and arranged on the diffusion film 200, ensuring that the preset pattern 210 is firmly attached to the diffusion film 200, which helps to reduce the problem of the preset pattern 210 falling off or shifting during use. Since the preset pattern 210 and the diffusion film 200 are integrally formed, the optical interface between the two is smoother, reducing the reflection and refraction loss of light on the interface, helping to optimize the light diffusion effect and improve the clarity and uniformity of the display image. The one-piece design can ensure the precise alignment between the preset pattern 210 and the diffusion film 200, avoid the problem of pattern misalignment or offset, and improve the positioning accuracy. The preset pattern 210 and the diffusion film 200 are integrally formed, and no additional attachment steps are required during the manufacturing process, which simplifies the production process and improves production efficiency.

[0070] In some embodiments, in combination Figure 1 , the preset pattern 210 is printed and set on the diffusion film 200. Compared with spraying, electroplating, physical deposition or 3D printing and other setting methods, the preset pattern 210 is processed by printing in one piece, and the material cost is greatly reduced. In addition, the printing setting process is mature and has high precision, which can ensure the uniformity and consistency of the preset pattern 210 and has high production efficiency. The preset pattern 210 adopts a printing process to achieve close fit on the surface of the diffusion film 200, which can better play its light scattering and homogenization role and improve the display effect.

[0071] In some embodiments, in combination Figure 1 The preset pattern 210 is printed on the diffusion film 200 by UV printing. For example, the preset pattern 210 is produced by image processing software such as AI and PS, and then the preset pattern 210 is printed on the diffusion film 200 by UV printing equipment.

[0072] In some embodiments, in combination Figure 1 The diffusion film 200 is provided with a shielding layer 220 in the circumferential direction of the preset pattern 210, which can effectively prevent light from leaking from the edge, thereby significantly improving the overall effect of the display image and making the pattern clearer and more delicate.

[0073] In some embodiments, the edge of the diffusion film 200 is bonded and fixed to the first polarizer 300, for example, by using double-sided tape 730, to avoid loosening or displacement that may occur during use. The tight bonding of the edge helps prevent light from leaking from the gap between the diffusion film 200 and the first polarizer 300. The bonding and fixation simplifies the manufacturing process and reduces production costs.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
