Description

Technical Field

[0001] This application relates to the field of displays, and more specifically to a display screen, a method for manufacturing the display screen, and an apparatus including the display screen. Background Technology

[0002] Display screens, as key windows for information interaction, are widely used in many fields such as home appliances, smart devices, and commercial media. Currently, based on the light-emitting unit, display screens can include LED displays, LCD displays, and others.

[0003] Generally, existing displays use LEDs mounted on a circuit board as a light source, and the circuit board controls the on / off state of the LEDs to control the content displayed on the screen. For different applications, the content to be displayed requires specially customized icons or characters, and these icons or characters are immutably embedded within the display, which restricts the versatility of the display and increases its manufacturing and management costs. Summary of the Invention

[0004] Therefore, the purpose of this application is to provide an improved display screen to solve at least one of the above-mentioned technical problems and other problems not mentioned.

[0005] According to a first aspect of this application, a display screen is provided, including a printed film, the printed film comprising: a printed film base; at least one first printed portion printed on the printed film base, the at least one first printed portion being configured to form a first visual element; and at least one second printed portion printed on the printed film base, the at least one second printed portion being configured to form a second visual element, wherein the display form of the first printed portion is fixed, and the display form of the second printed portion is adjustable.

[0006] Therefore, the adjustability of the display form of the second printing section enables the versatility of the display screen, meaning that the display form of the second printing section can be adjusted or changed according to actual needs to obtain the desired visual elements or combinations of visual elements. Simultaneously, the display screen can form corresponding visual elements solely through the light emission of the printing section itself, and the presentation of the corresponding visual elements can be adjusted by modifying at least one characteristic such as the form, shape, area, or arrangement of the printing section on the base of the printing film. This allows for the elimination of point light sources (e.g., LEDs) in existing circuit boards, thereby removing size limitations on the circuit board.

[0007] According to an optional embodiment of this application, the first visual element includes an icon; and / or the second visual element includes characters.

[0008] According to an optional embodiment of this application, the first printing section is a continuous printing area formed by continuously printing a first luminescent material, and the second printing section is a luminescent dot matrix formed by a second luminescent material. Advantageously, the surface light source of the first printing section, formed by printing, replaces the existing point light source, eliminating the need to consider crosstalk between point light sources. Furthermore, the second printing section, implemented as a dot matrix display module, allows for the provision of dynamic display content, providing users with more information services within a limited display area, thus enhancing the user experience and the perceived premium feel of the product.

[0009] According to an optional embodiment of this application, the printed film has a plurality of first printing sections and only one second printing section. This achieves a simple structure and arrangement.

[0010] According to an optional embodiment of this application, the first printing section and the second printing section are configured such that the first visual element and the second visual element can be displayed correspondingly, particularly in a one-to-one correspondence in position. Therefore, an explanation can be provided, for example, using the second visual element (e.g., text) for a corresponding first visual element (e.g., an icon).

[0011] According to an optional embodiment of this application, the display screen includes a circuit board, wherein each first printed section is configured to emit light independently and controllably, particularly controlled by a controller disposed in the circuit board via a first control loop. Additionally or alternatively, according to an optional embodiment of this application, each light-emitting point in the light-emitting dot matrix of the second printed section is configured to emit light in a controlled manner associated with position coordinates, particularly controlled by a controller disposed in the circuit board via a second control loop. Preferably, the emission sequence of each light-emitting point in the light-emitting dot matrix of the second printed section is controlled by a computer-edited program. Thus, independent control of the first and second printed sections can be achieved, particularly by a controller.

[0012] According to an optional embodiment of this application, the printed film is provided with a pattern associated with the first visual element, and the pattern area of ​​the printed film corresponds to the first printed portion. Therefore, the light emitted from the first printed portion can serve as backlight for the pattern area, thereby forming the corresponding first visual element.

[0013] According to an optional embodiment of this application, the display screen further includes: a cover plate; and a color film located between the printed film and the cover plate, wherein the color film has a pattern associated with the first visual element, and the pattern area of ​​the color film at least partially overlaps with the first printed portion along the depth direction of the display screen; preferably, the color film does not overlap with the second printed portion along the depth direction of the display screen. Therefore, light emitted from the first printed portion can illuminate the pattern area of ​​the color film located above the first printed portion to form a corresponding first visual element on the cover plate.

[0014] According to an optional embodiment of this application, the display screen further includes a cover plate having a pattern associated with the first visual element, the pattern area of ​​the cover plate corresponding to the first printing section. Therefore, directly setting the pattern on the cover plate facilitates the manufacturing of the printing film and simplifies or eliminates the need for a color film.

[0015] According to an optional embodiment of this application, the display screen further includes a touch detection unit configured to detect touch signals against the first visual element. Preferably, the touch signals are used to control at least a portion of the corresponding first printed portion. Therefore, the user's operational intent can be identified by means of the touch detection unit, thereby correspondingly controlling the first printed portion to emit light to provide the user with visual feedback corresponding to their operational intent.

[0016] According to an optional embodiment of this application, the printing film base is made of PC material or PET material.

[0017] According to an optional embodiment of this application, the thickness of the printed film is less than 2 mm, preferably less than 1.5 mm, and more preferably less than 1 mm. Additionally or alternatively, according to an optional embodiment of this application, the thickness of the display screen is less than 10 mm, preferably less than 7 mm, and more preferably about 5 mm. Therefore, a thin and light display screen can be advantageously achieved.

[0018] According to an optional embodiment of this application, the area of ​​the circuit board is smaller than the area of ​​the printed film, preferably about half the area of ​​the printed film. This facilitates miniaturization of the circuit board and lightweighting of the display screen, resulting in greater economic value.

[0019] According to an optional embodiment of this application, the minimum spacing between two adjacent printed portions is less than 1 mm, preferably less than 0.5 mm, and more preferably less than or equal to 0.1 mm. Therefore, the display screen 1 can have more refined display functions and more flexible light-emitting design without generating light crosstalk between light sources.

[0020] According to an optional embodiment of this application, the first luminescent material and the second luminescent material are the same. This simplifies the implementation of the printing process and the control of the luminescence of the printed film.

[0021] According to an optional embodiment of this application, the first luminescent material and the second luminescent material are at least one of organic electroluminescent materials and inorganic electroluminescent materials. Preferably, the first luminescent material and the second luminescent material are at least one of the following materials: OLED material; conductive polymer material; ZnS and quantum dot material.

[0022] According to a second aspect of this application, a method for manufacturing any of the displays according to this application is provided, comprising: providing a printing film base; and printing a first printing portion and a second printing portion respectively on the printing film base to form the printing film.

[0023] According to an optional embodiment of this application, the method further includes: after printing the first printed portion and the second printed portion, forming a pattern associated with a first visual element corresponding to the first printed portion of the printed film; and sequentially stacking and assembling the circuit board, the printed film, and the cover plate, wherein the printed film is configured such that the pattern area containing the pattern is closer to the cover plate relative to the first printed portion. Thus, the pattern is provided through the printed film.

[0024] According to an optional embodiment of this application, the method further includes: sequentially stacking and assembling the circuit board, the printed film, the color film, and the cover plate, wherein the color film has a pattern associated with a first visual element, and the color film is configured such that the pattern area containing the pattern at least partially overlaps with the first printed portion along the depth direction of the display screen. Thus, the pattern is provided through the color film.

[0025] According to an optional embodiment of this application, the method further includes: sequentially stacking and assembling the circuit board, the printed film, and the cover plate, wherein the cover plate has a pattern associated with the first visual element, and the cover plate is configured such that the pattern area containing the pattern at least partially overlaps with the first printed portion along the depth direction of the display screen. Thus, the pattern is provided through the cover plate.

[0026] According to a third aspect of this application, an apparatus is provided, including any of the displays according to this application.

[0027] Through certain embodiments of this application, displays can be endowed with wider versatility, more refined display functions, and lower manufacturing and management costs.

[0066] To make the technical problems to be solved, the technical solutions, and the beneficial technical effects of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and several exemplary embodiments. It should be understood that the specific embodiments described herein are only for explaining the principles of this application and are not intended to limit the scope of protection of this application. In the various drawings of this application, features with the same structure or similar function are indicated by the same or similar reference numerals.

[0067] In some devices, especially home appliances, it's common to provide both icons and characters on the display screen. For example, in some cases, characters should correspond one-to-one with icons and provide explanations for the images. Taking a washing machine as an example, the display screen, which serves as the user interface, typically needs to show characters such as "low," "medium," "high," "self-cleaning," and "delayed shutdown," along with their corresponding icons. These characters and icons guide the user in operating the display screen to control the washing machine.

[0068] In existing traditional display screen designs, methods such as using separate black and white films, separate pure color films, or combinations of color films and TFT displays are widely adopted.

[0069] Figure 1 An exploded decomposition diagram of an existing display screen 1' is shown. Figure 2 A cross-sectional schematic diagram of the existing display screen 1' is shown. (As shown) Figure 1 and Figure 2 As shown, a conventional display screen 1' typically includes a circuit board 100', a lamp well 200', a color filter 300', and a cover plate 400' stacked sequentially along its depth direction Z' (i.e., the stacking direction of each layer). The circuit board 100' has LED beads 101' serving as light emitters, disposed (e.g., by soldering). The lamp well 200' stacked on the circuit board 100' may include a lamp well base 201' and a cutout portion 202'. The area where the cutout portion 202' and the LED beads 101' are located needs to be aligned or overlapped with each other along the depth direction Z' so that the light emitted by the LED beads 101' can pass through the cutout portion 202' and propagate upwards towards the color filter 300'. The color filter 300' includes a color filter base 301' and printed elements printed on the color filter base 301', such as icons 302' and characters 303'. Therefore, the light emitted by the LED 101' can serve as the backlight for the printed elements on the color film 300', making it possible to see the corresponding visual elements displayed on the cover plate 400' from the outside.

[0070] When facing different consumer markets, icons often possess a certain degree of universality, allowing users to accurately understand their meaning. However, language differences necessitate corresponding text support (e.g., Chinese, English, German) for displays and related devices targeting different markets. Currently, the icons and characters used to create visual elements are printed onto films using a film printing method, which cannot be changed, limiting the universality of displays. Currently, it's necessary to prepare films with different text for different consumer markets, encapsulate them within the displays, and then deploy displays showing different text in each market. In other words, different color film versions are needed for different countries. Clearly, this increases the manufacturing and management costs of the films and displays.

[0071] The embodiments of this application advantageously provide a more general solution.

[0072] Figure 3 An exploded view of a display screen 1 according to an exemplary embodiment of this application is shown. Figure 4 It shows Figure 3 A cross-sectional schematic diagram of an exemplary display screen 1 according to this application is shown. Figure 3 and Figure 4 As shown, the display screen 1 according to an embodiment of the present application may include a printed film 200, which may include a printed film base 201 and at least one first printed portion 202 and at least one second printed portion 203 respectively printed on the printed film base 201, wherein at least one first printed portion 202 is configured to form a first visual element E1 and at least one second printed portion 203 is configured to form a second visual element E2. Figure 6 A first visual element E1 and a second visual element E2 are illustrated exemplarily. Specifically, the display form of the first printing section 202 is fixed, while the display form of the second printing section 203 is adjustable. Here, the display form may include, but is not limited to, at least one of brightness, pattern, color, shape, and dynamic changes.

[0073] Therefore, the adjustability of the display form of the second printing section 203 can make the display screen 1 versatility possible, that is, the display form of the second printing section 203 can be adjusted or changed according to actual needs to obtain the desired visual elements or combinations of visual elements.

[0074] Embodiments of this application also provide a method for manufacturing such a display screen 1, the method comprising:

[0075] - Provides a printing film base 201; and

[0076] - A first printing portion 202 and a second printing portion 203 are printed on the printing film base 201 to form the above-mentioned printing film 200.

[0077] Advantageously, the display screen 1 according to the embodiments of this application can form corresponding visual elements solely by relying on the light emission of the printing portion of the printing film 200 itself, and the presentation of the corresponding visual elements can be adjusted by adjusting at least one feature such as the form, shape, area, or arrangement of the printing portion on the printing film base 201, thereby allowing the cancellation of features such as... Figure 1The LEDs 101' in the conventional display screen 1' shown are arranged in the circuit board 100'. Therefore, the circuit board 100 in the display screen 1 does not need to have approximately the same size as the lamp well 200' and color filter 300' as the circuit board 100' in the conventional display screen 1'. Advantageously, in an alternative embodiment according to this application, the area of ​​the circuit board 100 of the display screen 1 can be smaller than the area of ​​the printed film 200, preferably about half the area of ​​the printed film 200. This can facilitate the miniaturization of the circuit board 100 and the lightweight of the display screen 1, making it more economical.

[0078] Furthermore, in existing display screens 1', to avoid light crosstalk caused by point light sources such as LED beads 101' and achieve light uniformity, it is necessary to ensure that the lamp wells 200' have a certain thickness, and the spacing between the cutouts 202' cannot be too small. For example, the thickness of the lamp wells 200' is typically in the range of about 10 mm to about 20 mm. However, advantageously, since the display screen 1 according to the embodiments of this application uses a printed film with luminous printed portions, the use of lamp wells 200' can be eliminated. This can save on development costs, material costs, and processing costs associated with lamp wells, and can significantly reduce the thickness of the display screen 1, thereby contributing to the lightweight and flexible design of the display screen 1 and simplifying its implementation. Meanwhile, in the display screen 1 according to the embodiments of this application, each printed portion is formed by a printing process, thus advantageously ensuring that the minimum spacing between two adjacent printed portions 202, 203 is less than 1 mm, preferably less than 0.5 mm, and more preferably less than or equal to 0.1 mm. Therefore, the display screen 1 can have more refined display functions and more flexible light-emitting design.

[0079] Preferably, the thickness of the printed film 200 in the display screen 1 according to the embodiments of this application can be less than 2 mm, more preferably less than 1.5 mm, and more preferably less than 1 mm. Additionally or alternatively, the thickness of the display screen 1 according to the embodiments of this application can be less than 10 mm, more preferably less than 7 mm, and more preferably about 5 mm.

[0080] Optionally, the first visual element E1 may include an icon. Additionally or alternatively, the second visual element E2 may include characters. Here, the icon may be fixed, while the characters may be adjustable. For example, in some exemplary embodiments, the characters may include explanatory text for the icon in different languages ​​such as Chinese and English, a power-on welcome language, a power-off language, dynamic content prompts such as remote upgrade prompts, etc. The second visual element E2 may be provided selectively based on program settings and / or in response to user operations on the display screen 1 or the corresponding device. The icon may be provided by a printed pattern, which, as will be described in detail below, may be provided, for example, by the printing film 200 itself, the color film 300, or the cover plate 400.

[0081] Figure 5 shows Figure 3 a schematic diagram of the printed film of the exemplary display screen according to the present application. As shown in Figure 5 , the printed film 200 may have a plurality of first printing portions 202 and only one second printing portion 203. Additionally or alternatively, the first printing portion 202 and the second printing portion 203 may be configured such that the first visual element E1 and the second visual element E2 can be displayed correspondingly, in particular displayed in one-to-one correspondence in position. Therefore, for example, the second visual element E2 (such as text) can be used to provide an explanation for the corresponding first visual element E1 (such as an icon).

[0082] In a specific exemplary embodiment, the printed film 200 in the display screen may be printed with a plurality of icons as the first visual elements E1. For example, if the display screen is to be used in a laundry treatment apparatus, the icons may include respective icon symbols representing machine switch, program start / stop, different washing programs, washing program parameters (such as temperature, rotation speed), fault types, energy saving and environmental protection, and the like. These icon symbols represent different functions and operations. Through these symbols, the user can select a washing program, adjust washing parameters, troubleshoot faults, and even select an energy saving mode, etc. Meanwhile, the printed film 200 in the display screen may have the second printing portion 203. Under the control of the controller, the second printing portion 203 can emit light to present text corresponding to one of these icon symbols, for example, Chinese will be displayed on the laundry treatment apparatus for the Chinese market, while English or other foreign languages will be adaptively displayed on the laundry treatment apparatus for the European and American markets. For example, for the icon symbol representing "pause", the Chinese character "暂停" is displayed for Chinese users, while the English word "PAUSE" is displayed for European and American users. The user, or the seller or manufacturer of the laundry treatment apparatus can select and set according to actual needs. This can be performed separately after the manufacturing process of the display screen and the laundry treatment apparatus is completed. This selective presentation of text can be completely based on the program setting of the controller, without the need to provide display screens with color films carrying different language texts for different countries or consumer markets. Therefore, great convenience can be brought to the manufacture of display screens and the manufacture and management of multiple film versions with different language texts.

[0083] It should be understood that within the scope of the present application, the shape, number, layout and the like of the first printing portion 202 and the second printing portion 203 in the printed film 200 can be arbitrarily adjusted as required.

[0084] Preferably, the first printing portion 202 may be a continuous printed region formed by continuously printing a first luminescent material, and the second printing portion 203 is a luminescent dot matrix formed by a second luminescent material.

[0085] Advantageously, instead of point light sources like LED beads 101' in the existing display screen 1', a surface light source like the first printed section 202 formed by printing is used, eliminating the need to consider crosstalk between point light sources. The second printed section 203 can be implemented as a dot matrix display module, thereby providing dynamic display content and offering users more information services within a limited display area, contributing to an improved user experience and a premium feel. Furthermore, the light emitted by the first printed section 202 can serve as backlight for fixed icons, while the second printed section 203 can directly display characters. Therefore, the printed film 200 can simultaneously achieve backlighting and character display.

[0086] Here, the first luminescent material and the second luminescent material can be the same. This simplifies the implementation of the printing process and the luminescence control of the printed film. Additionally or alternatively, the first luminescent material used to form the first printed portion 202 and the second luminescent material used to form the second printed portion 203 can be at least one of organic electroluminescent materials and inorganic electroluminescent materials. Preferably, the first luminescent material and the second luminescent material are at least one of the following materials: OLED materials; conductive polymer materials; ZnS and quantum dot materials. The conductive polymer materials may include, but are not limited to, polyaniline and polythiophene.

[0087] Alternatively, the printing film base 201 can be made of PC material or PET material.

[0088] Return to Figure 3 and Figure 4 The display screen 1 may also include a circuit board 100, which can be disposed below the printed film 200. The circuit board 100 may include a controller 500, and a first control loop 510 and a second control loop 520 for the first printed section 202 and the second printed section 203, respectively. That is, the first printed section 202 and the second printed section 203 have separate wiring and are respectively connected to the controller 500. Thus, the controller 500 can achieve independent control of the first printed section 202 and the second printed section 203.

[0089] Figure 7 A schematic diagram of the electrical control of a display screen according to an exemplary embodiment of this application is shown.

[0090] Each arrow represents a single light-emitting element, that is, a light-emitting point in the light-emitting dot matrix of the first printing section 202 or the second printing section 203. For example... Figure 7As shown, each first printed section 202 can be configured to emit light independently of each other, specifically controlled by a controller 500 provided in the circuit board 100 via a first control loop 510. Additionally or alternatively, each light-emitting dot in the light-emitting dot matrix of the second printed section 203 is configured to emit light in a controlled manner associated with its position coordinates, specifically controlled by a controller 500 provided in the circuit board 100 via a second control loop 520.

[0091] Preferably, the light emission sequence of each light emission point in the light emission dot matrix of the second printing section 203 is controlled by a computer-edited program. That is, the required light emission sequence can be compiled in a computer programming language and stored in the controller 500, or it can be stored in the control unit of the device with the display screen 1 to achieve corresponding light emission control through communication with the controller 500.

[0092] Optionally, the display screen 1 may further include a touch detection unit (not shown in the figure), which is configured to detect touch signals against the first visual element E1. Preferably, the touch signal is used to control at least a portion of the corresponding first printed portion 202. For example, when a user touches the display area of ​​the first visual element E1 (e.g., the area of ​​an icon), the touch detection unit can detect the corresponding touch signal. Based on the touch signal, the controller 500 can control the first printed portion 202 or a portion thereof corresponding to the display area of ​​the touched first visual element E1 to emit light.

[0093] Regarding the provision of the pattern associated with the first visual element E1, this application provides three specific examples. Correspondingly, three different manufacturing methods are also provided for these three different examples.

[0094] <First Example>

[0095] The printing film 200 can provide a pattern associated with the first visual element E1, and the pattern area of ​​the printing film 200 corresponds to the first printing section 202. Thus, when the first printing section 202 emits light, the pattern area can be directly illuminated, that is, the light emitted by the first printing section 202 can serve as the backlight for the pattern area, thereby forming the corresponding first visual element E1.

[0096] In connection with this example, a manufacturing method according to an embodiment of this application may further include:

[0097] - After the first printed portion 202 and the second printed portion 203 are formed, a pattern associated with the first visual element E1 is formed corresponding to the first printed portion 202 of the printed film 200; and

[0098] - The circuit board 100, the printed film 200 and the cover plate 400 are stacked and assembled in sequence, wherein the printed film 200 is configured such that the pattern area where the pattern is located is closer to the cover plate 400 relative to the first printed part 202.

[0099] Here, for example, after the first printed portion 202 and the second printed portion 203 are formed, a protective layer can be superimposed, and a pattern can be printed on the protective layer to form a corresponding pattern area. The first printed portion 202 and / or the second printed portion 203 can be located on the same side or opposite side of the printed film 200 as the pattern area. Thus, the display screen 1 in the first example can be realized. In this first example, it is not necessary to provide a color film, but rather to rely solely on the printed film 200 itself to provide a fixed pattern.

[0100] <Second Example>

[0101] The display screen 1 may include a cover plate 400 and a color filter 300 located between the printed film 200 and the cover plate 400. The color filter 300 may have a color filter base 301 and a pattern printed on the color filter base 301 associated with the first visual element E1. The pattern area 302 of the color filter 300 (e.g., ...) is where the pattern of the color filter 300 is located. Figure 3 As shown, the first printed section 202 at least partially overlaps with the first printed section 202 along the depth direction Z (i.e., the stacking direction of each layer) of the display screen 1. Thus, when the first printed section 202 emits light, the light can illuminate the pattern area 302 of the color film 300 located above the first printed section 202 to form a corresponding first visual element E1 on the cover plate 400.

[0102] Here, the pattern area 302 where the pattern of the color filter 300 is located can partially overlap or completely overlap with the first printing section 202 along the depth direction Z of the display screen 1. That is, the light emitted by the first printing section 202 can serve as the backlight of the corresponding pattern area 302 of the color filter 300 so as to form the corresponding first visual element E1.

[0103] Preferably, the color filter 300 does not overlap with the second printing section 203 along the depth direction Z of the display screen 1. That is, within the lateral extension range perpendicular to the depth direction Z, the width of the color filter 300 can be shorter than the width of the printing film 200 to make room for the area corresponding to the second printing section 203, so that the content presented by the second printing section 203 through light emission can be directly displayed as the second visual element E2 on the cover plate 400.

[0104] In connection with this example, a manufacturing method according to an embodiment of this application may further include:
