They are low-cost, have good light transmittance, and have excellent mechanical properties. However, since the display panel is a transparent shell or thin plate, the light will be refracted after passing through the transparent material. Therefore, the light generated on the display panel will have a halo phenomenon, that is, there will be extra apertures, affecting the clarity of the light points on the display panel.

[0024] 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. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0025] See also Figure 1-3 ,in Figure 2 The dotted line portion indicates the second surface 12 of the transparent substrate 1. The embodiment of the utility model provides a display panel with a light shielding ring, comprising: a transparent substrate 1, the substrate having a first surface 11 and a second surface 12 arranged in parallel, the first surface 11 is used to face the outside world, and the second surface 12 is used to face the point light source 21; the first surface 11 has at least one light-transmitting area 112, and a printing area 111 arranged on the periphery of the light-transmitting area 112, the printing area 111 is provided with a printing layer, and the printing layer is used to shield the light shielding ring.

[0026] The transparent substrate 1 has a certain thickness, and has a first surface 11 and a second surface 12 in the thickness direction, wherein the first surface 11 is used to face the outside, such as for being touched by a user, and the second surface 12 faces the point light source 21, and there is one or more light-transmitting areas 112 on the first surface 11. The second surface 12 faces the side with the point light source 21, so that the point light source 21 can irradiate the first surface 11 through the light-transmitting area 112, thereby forming a light spot on the first surface 11.

[0027] Since the substrate is made of transparent material, the light emitted by the point light source 21 will be refracted after passing through the transparent material. If the light from the point light source 21 is directly emitted onto the untreated transparent substrate 1, not only a light spot will be displayed on the first surface 11, but also an aperture will be displayed on the first surface 11 and around the light spot, that is, a halo phenomenon will be generated. This phenomenon is an abnormal phenomenon, which will cause blurred vision and weakened light spots during use.

[0028] In the embodiment of the utility model, the printing area 111 of the base plate is provided with a printing layer. Since the printing area 111 is distributed around the light-transmitting area 112, the printing layer can cover the aperture formed on the first surface 11 and around the light-transmitting area 112. Therefore, the display panel of the embodiment of the utility model only displays light spots on the first surface 11, and does not display the aperture, thereby effectively solving the technical problem of the halo phenomenon.

[0029] Exemplarily, the material of the base plate is PMMA (Polymethyl Methacrylate), transparent PC (Polycarbonate) or glass or other transparent materials, which is not specifically limited in the embodiments of the present invention.

[0030] Furthermore, the printing layer is printed on the printing area 111 by using a screen printing process.

[0031] Most display panels have additional printing and film laminating processes to increase product functionality and improve product appearance quality. However, the traditional printing film method usually uses an in-mold injection molding process to integrate the printed film and the plastic panel, but this can easily lead to partial separation of the printed film and the plastic panel during maintenance (or disassembly). At the same time, the traditional printing film method still has the problem of haloing on the display panel.

[0032] The embodiment of the utility model adopts the process of screen printing. Specifically, screen printing refers to using a screen as a base and making a screen printing plate with images and texts through a photosensitive platemaking method. The screen printing process adds a printing layer on the side of the display panel away from the light source. On the one hand, the problem of partial separation of the printing film and the plastic panel can be avoided; on the other hand, the printing layer can also block the aperture, thereby effectively preventing the occurrence of halo phenomenon on the display panel.

[0033] Furthermore, the printing area 111 includes 1-8 printing layers. Specifically, a printing area 111 may include 1, 2, 3, 4, 5, 6, 7 or 8 printing layers. The specific setting can be based on actual needs. Different layers of printing layers can be printed on the first surface 11 in sequence. The total printing layer thickness of the printing area 111 is determined by the thickness of a single printing layer and the number of printing layers. When the thickness of a single printing layer is constant, the more the number of printing layers, the thicker the overall thickness of the printing area 111, so that the printing area 111 can completely block the aperture and enhance the appearance quality of the display panel.

[0034] Furthermore, the printing layer is an ink layer or a paint layer. Specifically, the material of the printing layer can be ink or paint. The ink or paint is printed on the first surface 11, that is, printed on the side away from the light source, so that the ink or paint can block the aperture and avoid the occurrence of halo phenomenon.

[0035] In addition, for the same display panel, different printing layers may use the same or different materials. For example, the printing area 111 has three printing layers, the material of the first printing layer is ink, the material of the second printing layer is ink, and the material of the third printing layer is paint; or, the materials of the three printing layers are all ink.

[0036] Furthermore, the thickness of a single printed layer ranges from 0.05 to 0.25 mm. Specifically, the thickness of a single printed layer can be 0.05, 0.08, 0.09, 0.1, 0.11, 0.12, 0.13, 0.14, 0.15, 0.18, 0.2, 0.22, or 0.25 mm, etc. The total printed layer thickness of the printed area 111 is determined by the thickness of the single printed layer and the number of printed layers. When the number of printed layers is constant, the thicker the thickness of the single printed layer, the thicker the overall thickness of the printed area 111, so that the printed area 111 can completely block the aperture and enhance the appearance quality of the display panel.

[0037] In addition, for the same display panel, the thicknesses of different printing layers may be the same or different. For example, the printing area 111 has four printing layers, the thickness of the first printing layer is 0.12 mm, the thickness of the second printing layer is 0.1 mm, the thickness of the third printing layer is 0.1 mm, and the thickness of the fourth printing layer is 0.08 mm; or, the thickness of the four printing layers is 0.1 mm.

[0038] Furthermore, the thickness of the display panel is between 1-3 mm. Specifically, the thickness of the display panel can be 1, 1.5, 1.8, 1.9, 2, 2.1, 2.2, 2.3, 2.4, 2.5, 2.8 or 3 mm, etc. The appearance and quality requirements of the display panel can be guaranteed, and excellent mechanical properties can be reflected. The specific thickness can be set according to actual needs.

[0039] Furthermore, in some embodiments, the shape of the light-transmitting area 112 includes a circle, a square, a rectangle, an ellipse or a trapezoid. In other embodiments, the shape of the light-transmitting area 112 can also be other regular shapes, or irregular shapes, etc. The light of the point light source 21 is displayed in the form of a light spot through the light-transmitting area 112, and the shape of the light-transmitting area 112 determines the shape of the light spot. The embodiment of the utility model does not limit the specific shape of the light-transmitting area 112.

[0040] Furthermore, the radial dimension of the light-transmitting area 112 is between 2-5 mm. Specifically, the radial dimension of the light-transmitting area 112 can be 2, 2.5, 3, 3.5, 4, 4.5, 5 mm, etc., and can be the maximum radial dimension, the minimum radial dimension, or the average radial dimension. The size of the light-transmitting area 112 depends on the size of the light spot. The size of the light-transmitting area 112 can be equal to the size of the light spot, or smaller than the size of the light spot, so that the printed layer arranged on the periphery of the light-transmitting area 112 can completely block the aperture on the periphery of the light spot. The specific size can be determined according to actual needs.

[0041] Furthermore, a display screen includes a circuit board 2 and a display panel as above, wherein the circuit board 2 is mounted on a second surface 12, and at least one point light source 21 is provided on a side of the circuit board 2 facing the second surface 12, the number of light-transmitting areas 112 corresponds to the number of point light sources 21, and the point light sources 21 are aligned with the light-transmitting areas 112.

[0042] Specifically, the display screen includes a circuit board 2 and a display panel, and the point light source 21 can be a lamp bead arranged on the circuit board 2. The second surface 12 of the display panel faces the lamp bead side of the circuit board 2, and the light-transmitting area 112 of the first surface 11 is arranged corresponding to the number and position of the lamp beads, so that the light emitted by the lamp beads can pass through the light-transmitting area 112 and display a bright spot on the first surface 11. Since the printing area 111 is distributed on the peripheral side of the light-transmitting area 112, the printing layer can cover the aperture formed on the first surface 11 and on the peripheral side of the light-transmitting area 112. Therefore, the display screen of the embodiment of the utility model only displays light spots on the first surface 11, and does not display the aperture, thereby effectively solving the technical problem of generating the halo phenomenon.

[0043] Furthermore, an electronic device includes the display screen as above. Specifically, in practical applications, the electronic device can be a medical humidifier, etc. The electronic device of the embodiment of the utility model only displays light spots on the first surface 11, but does not display an aperture, thereby effectively solving the technical problem of halo phenomenon.

[0044] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0045] The above is a description of the technical solution provided by the utility model. For technicians in this field, according to the ideas of the embodiments of the utility model, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the utility model.
