Abstract
Description
Technical Field
[0001] This application relates to the field of electronic screen technology, and more specifically, to an electronic ink screen and a touch screen electronic device. Background Technology
[0002] E-ink screens have many advantages, such as readability and low power consumption, display flexibility, environmental friendliness and visual health, image preservation, and a wide range of applications, which have permeated various industries and are becoming an important direction for the development of display technology.
[0003] Due to differences in the light-emitting principle, materials, and manufacturing process of E Ink screens, which are not as transparent as traditional LCD screens, a light guide plate is placed in front, also known as "front light." Front light typically uses two different light sources, warm light and cool light, which are adjusted and combined through software to create different effects.
[0004] The front light is projected from the side through an LED light strip into a light guide plate, which transforms the point light source into a surface light source. However, the design of the front LED light strip does not completely block the front light, resulting in light leakage at the edge of the E Ink screen's markings after it is attached to the touchscreen. This leakage is easily noticeable to the human eye and affects the product's performance and quality. Utility Model Content
[0005] The purpose of this application is to provide an electronic ink screen that can effectively improve the light leakage phenomenon at the edge markings of the E Ink screen and improve the performance and quality of the screen product.
[0006] To achieve the above objectives, in a first aspect, this utility model provides an electronic ink screen, including a protective screen panel and an electronic paper screen. The electronic paper screen has a screen light source inside, the protective screen panel includes a screen frame edge, and screen marking ink is disposed on the screen frame edge. The screen marking ink includes ink particles.
[0007] The screen marking ink is positioned to avoid the mounting location of the screen light source;
[0008] Alternatively, the ink portion of the screen marking may be provided with a light-blocking layer.
[0009] In an optional embodiment, the screen light source and the screen marking ink are staggered and avoid each other in the thickness direction of the e-ink screen, and the screen marking ink is disposed opposite to the outside of the screen light source.
[0010] In an optional embodiment, the light-shielding layer includes a black light-shielding layer disposed between the protective screen and the electronic paper screen, the black light-shielding layer shielding and covering the mounting area of the screen light source.
[0011] In an optional embodiment, the black light-shielding layer includes a black polyester film tape adhered to the electronic paper screen, and the adhesion position is vertically opposite to the installation position of the screen light source.
[0012] In an optional embodiment, the light-blocking layer includes a white base ink covering the screen marking ink, the white base ink being disposed between the protective screen panel and the screen marking ink.
[0013] In an optional embodiment, a regularly shaped marking area is provided on the edge of the screen frame, the screen marking ink is disposed within the marking area, and the white cover ink includes a regularly shaped cover area, which is disposed directly above the marking area and completely covers the marking area.
[0014] In an optional implementation, the size of the cover area is not smaller than the size of the marking area.
[0015] In an optional embodiment, the screen light source includes an LED light strip, which comprises a long strip of light located inside the electronic paper screen.
[0016] In an optional implementation, the protective screen panel includes a single-piece glass screen, an acrylic glass screen, or an external glass screen.
[0017] Secondly, this utility model provides a touch screen electronic device, including the electronic ink screen described in any of the foregoing embodiments.
[0018] By setting screen marking ink on the edge of the screen frame of the protective screen, it is possible to display specific brand or model markings on the screen, thereby expanding the display types of e-ink screens and enhancing the visual experience of e-ink screens.
[0019] By combining screen label ink with ink particles, the three-dimensional effect of the screen label can be enhanced, thus improving the quality of the e-ink screen.
[0020] Based on the setting of screen marking ink, by making the screen marking ink relatively avoid the installation position of the screen light source, or by setting a light-blocking layer on the screen marking ink area, the problem of light leakage of the screen light source through ink particles can be solved by staggering the positions or blocking the diffused light from the top of the screen light source. Thus, the performance of the e-ink screen is guaranteed while improving the quality of the e-ink screen.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0036] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0038] See Figure 1 and combined Figures 2-6 The electronic ink screen in this application is mainly used to prevent light from passing through the screen marking ink 12 in the form of ink particles in the electronic paper screen 4, thus preventing light leakage at the screen marking ink 12.
[0039] In the specific improvement process, the main methods used are to reduce the light transmission effect of the screen light source on the screen marking ink 12 by alternating the arrangement of the screen marking ink 12 and the screen light source inside the electronic paper screen 4, and by setting a light-blocking layer.
[0040] Based on the existing form of light source entering the light guide plate from the side in the e-ink screen, the direction of light from the light source has a component that is towards the top, i.e. towards the reader. This component of light will directly affect the ink on the top protective screen 2. This utility model is mainly aimed at improving the effect of this part of the light on the screen marking ink 12.
[0041] The specific improvements include two forms. In one form, by making the screen marking ink 12 relatively avoid the installation position of the screen light source inside the electronic paper screen 4, the coverage of the screen marking ink 12 by the above-mentioned top direction component light can be avoided, thereby preventing light transmission at the screen marking ink 12 area.
[0042] In another form, intervention is carried out by necessary light-blocking layer to block the possibility of top-direction light passing through the screen marking ink 12, thereby avoiding the visual impact on the screen marking ink 12.
[0043] Specifically, the electronic ink screen of this utility model consists of a protective screen 2 and an electronic paper screen 4. The screen light source is located inside the electronic paper screen 4 to provide the necessary light for the electronic paper screen 4.
[0044] The protective screen panel 2 includes a screen frame edge 1, which is specifically a border-shaped area set on the periphery of the protective screen panel 2. The inner side of the screen frame edge 1 constitutes the display area of the electronic paper screen 4. Specifically, by setting a base ink layer 11 on the edge of the protective screen panel 2, a black base can be formed around the periphery of the electronic ink screen, forming the screen frame edge 1.
[0045] By setting screen logo ink 12 on the base ink layer 11 of the screen frame 1 at the position of screen logo 16, a specific brand or model can be displayed on the screen frame 1, thereby making full use of the space area of the frame base and expanding the types of display logos on the e-ink screen.
[0046] By setting the screen logo ink 12 in the form of ink particles, the three-dimensional effect of the screen logo ink 12 can be enhanced, thereby improving the visual appearance of the screen brand or model logo and effectively ensuring the quality of the e-ink screen.
[0047] In order to prevent light leakage caused by the top component of the screen light source in the three-dimensional marking area, the screen marking ink 12 is positioned relatively away from the installation position of the screen light source, based on the ink particles. Alternatively, a light-blocking layer is provided on the screen marking ink 12 to reduce the light leakage caused by the screen light source to the screen marking ink 12.
[0048] Based on the different improvements already described, the following will be explained through different embodiments.
[0049] Example 1
[0050] Combination Figure 2 In this embodiment, the electronic ink screen avoids the top component light from irradiating the screen marking ink 12 by staggering the screen light source and the screen marking ink 12 in the thickness direction of the electronic ink screen, thereby reducing light leakage at the screen marking ink 12.
[0051] Based on the light guiding of the screen light source on the electronic paper screen 4, in order to reduce the illumination of the screen marking ink 12 by the oblique light, the screen marking ink 12 in this embodiment is arranged on the outside of the screen light source. By this arrangement, the screen light source can be fundamentally avoided from covering the screen marking ink 12, thereby effectively preventing light leakage from the screen marking ink 12.
[0052] In this configuration, the width of the base ink layer 11 at the edge of the protective screen panel 2 should be fully considered to provide sufficient space for the screen marking ink 12 to be installed on the screen frame.
[0053] Example 2
[0054] Combination Figure 3 In this embodiment, the light-shielding layer includes a black light-shielding layer 5 disposed between the protective screen panel 2 and the electronic paper screen 4. Furthermore, the black light-shielding layer 5 shields and covers the installation area of the screen light source.
[0055] In this configuration, the black light-shielding layer 5 can completely block the light emitted by the screen light source, so that the light at the bottom of the protective screen 2 is blocked by the black light-shielding layer 5, thereby preventing the top component of light from passing through the electronic paper screen 4.
[0056] Specifically, the black light-shielding layer 5 includes a black polyester film tape adhered to the electronic paper screen 4. Preferably, the black polyester film tape can be in the form of black Mylar tape, which is directly adhered to the top surface of the electronic paper screen 4 to shield the light leakage of the screen light source on the electronic paper screen 4.
[0057] By positioning the black polyester film tape vertically opposite the screen light source inside the electronic paper screen 4, a spatial isolation effect can be created, preventing the top component of light from passing through the electronic paper screen 4.
[0058] Example 3
[0059] Combination Figures 4-5 In this embodiment, the light-blocking layer includes a white base ink 13 covering the screen marking ink 12. In order to prevent the screen light source below the ink from transmitting light through the three-dimensional marking part of the screen marking ink 12 and causing a certain degree of light leakage, a white base ink 13 is covered on the top of the ink particles to form the base ink layer of the screen marking ink 12.
[0060] By setting a white overlay ink 13 on the upper part of the screen marking ink 12, a cover effect is formed on the screen marking ink 12, which prevents the screen light source below the ink from transmitting light through the screen marking ink 12, thereby improving the quality and performance of the e-ink screen.
[0061] The cover ink layer can effectively cover the screen light source through light leakage by the particulate ink while ensuring that the screen mark 16 is displayed normally. This can avoid light leakage at the edge of the electronic ink screen and maximize the performance and quality of the screen product.
[0062] By placing the white cover ink 13 between the protective screen plate 2 and the screen marking ink 12, the screen marking ink 12 can be effectively covered.
[0063] The white cover ink 13 in this embodiment is different from the light-blocking layer in embodiment 2. The black light-blocking layer 5 in embodiment 2 is between the protective screen 2 and the electronic paper screen 4, blocking the irradiation path of the top component light, and is a physical cover below the protective screen 2.
[0064] In this embodiment, the white cover ink 13 reduces the further spread of light through the screen marking ink 12 by covering it, thereby visually reducing the light leakage effect.
[0065] In this embodiment, a regularly shaped marking area 15 is provided on the screen frame edge 1. Preferably, the marking area 15 includes a rectangular area, which facilitates the screen printing of the marking on the screen frame edge 1 and also facilitates the coverage of the cover ink layer on the regularly shaped marking area 15.
[0066] Furthermore, the white cover ink 13 in this embodiment includes a cover area 14 with a regular shape. Based on the above-described marking area 15 including a rectangular area, the cover area 14 of the cover ink layer is also a rectangular area, which facilitates the screen printing operation of the white cover ink 13.
[0067] In this embodiment, the bottom cover area 14 is positioned directly above the marking area 15 and completely covers the marking area 15. This arrangement allows for comprehensive, all-around coverage of the marking area 15 without any blind spots, ensuring effective light blocking.
[0068] To minimize the risk of light leakage, the size of the cover area 14 formed by the cover ink layer is not smaller than the size of the marking area 15.
[0069] As mentioned above, both the cover area 14 and the marking area 15 are rectangular. In one specific configuration, the cover area 14 and the marking area 15 are rectangular with the same dimensions. By overlapping them, the white cover ink 13 covers the entire marking area 15.
[0070] In another specific configuration, the rectangular size of the cover area 14 is larger than the rectangular size of the marking area 15. By aligning the centers of the two rectangular areas, the white cover ink 13 extends and covers the marking area 15, further ensuring the stability and reliability of the light-blocking effect.
[0071] In this embodiment, by covering the upper part of the ink particles with white cover ink 13, a cover area 14 for the screen marking ink 12 is formed, thereby solving the technical problem that the ink particles cannot effectively cover the light leakage of the LED light strip 3.
[0072] The formulation and components of white overlay ink 13 include:
[0073] Ink type ratio (g)
[0074] CRT-211 white ink 60g±1
[0075] Hardener HT-70R 6g±0.2
[0076] Additive R-602g±0.1
[0077] Diluent K 156g ± 0.1
[0078] Recommended printing parameters include:
[0079] Squeegee hardness, printing speed, squeegee angle, screen distance
[0080] 70-80 degrees, 100-200 mm / s; 70-80 degrees, 4-6 mm
[0081] The above methods can achieve a good base ink layer, ensuring an effective and reliable light-blocking effect, thereby maximizing the performance and quality of the e-ink screen.
[0082] Combination Figure 2 , Figure 3 as well as Figure 6 The screen light source in this utility model includes an LED light strip 3. The LED light strip 3 directs the oblique illumination light into the light guide plate from the side. In order to ensure that the side illumination light can fully cover the display area of the electronic paper screen 4, the LED light strip 3 includes a long strip of light located inside the electronic paper screen 4.
[0083] Furthermore, the LED light strip 3 is set on the same side of the screen frame 1, preferably a long strip light strip located on the bottom edge of the screen frame 1, which can effectively direct the front light emitted by the LED light strip 3 into the light guide plate from the bottom side, while ensuring the effective display of the screen logo 16.
[0084] From the perspective of specific structural settings, the LED light strip 3 is embedded inside the electronic paper screen 4, which is located at the lower part of the protective screen plate 2. At the same time, the LED light strip 3 is located below the screen logo 16, and the white cover ink 13 is located between the protective screen plate 2 and the screen logo ink 12. Alternatively, the black light-shielding layer 5 can be located between the protective screen plate 2 and the electronic paper screen 4. This can ensure the visual appearance of the screen logo 16 while minimizing light leakage.
[0085] The electronic ink screen of this utility model avoids the impact of light leakage on the display of screen logo 16 without changing the screen logo ink 12 in the form of ink particles, based on the unavoidable light leakage phenomenon of LED light strip 3 on electronic paper screen 4.
[0086] From a specific analytical perspective, by analyzing the bonded structural layers and disassembling individual units, it was ultimately confirmed that the LED light strip 3 of the electronic paper screen 4 has an unavoidable light leakage phenomenon.
[0087] The reason for the light leakage of the screen logo 16 is that the light leakage of the LED light strip 3 on the electronic paper screen 4 passes through the screen logo ink 12 in the form of ink particles on the screen frame edge 1. The further reason is that although the ink particles can ensure the three-dimensional visual effect of the screen logo 16, they cannot effectively cover the light leakage of the LED light strip 3.
[0088] Therefore, this utility model avoids the light leakage effect caused by visually by using different settings to avoid blocking the top direction component light or weakening the top direction component light in the screen marking ink 12.
[0089] The electronic ink screen of this invention is applicable to different types of protective screen panels 2, including different types such as OGS monolithic glass screen with front light matching electronic paper screen 4, OGM organic glass screen, or CG external glass screen, thus broadening the application scope of electronic ink screen.
[0090] Based on the e-ink screen described above, this utility model also provides a touch screen electronic device, including the aforementioned e-ink screen, which can improve the performance and quality of the touch screen electronic device and enhance the user experience.
[0091] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0092] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
