Description

Technical Field

[0001] The present application belongs to the technical field of electronic equipment, and specifically relates to a display module and an electronic device. Background Art

[0002] In the related art, the increasing importance of information security during the use of electronic devices has made screen display anti-peeping functions particularly important. In recent years, electronic devices have used pixel segmentation to achieve independent control of anti-peeping sub-pixels and shared pixels. However, when the electronic device is in the anti-peeping state, light still emits from both sides of the display panel, allowing the screen information to be seen by people around, and the anti-peeping function of the electronic device is less effective. Utility Model Content

[0003] The present application aims to provide a display module and an electronic device, which at least solve one of the problems of poor anti-peeping function of electronic devices.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] In a first aspect, the present application proposes a display module comprising a substrate, a light-emitting unit, a packaging component, and a light-collecting component. The light-emitting units are multiple and arranged in parallel on the substrate. Each of the light-emitting units comprises a first light-emitting portion and a second light-emitting portion, with the second light-emitting portion arranged around the first light-emitting portion. The packaging component covers the light-emitting unit. The light-collecting component is arranged within the packaging component, opposite the first light-emitting portion, and is capable of converging the light emitted by the first light-emitting portion.

[0006] The display module defined in the present application includes a substrate, a light-emitting unit, a packaging component and a focusing component. A plurality of light-emitting units are arranged in parallel on the substrate, and each of the plurality of light-emitting units includes a first light-emitting portion and a second light-emitting portion, and the second light-emitting portion is arranged around the first light-emitting portion. Through the first light-emitting portion and the second light-emitting portion, the display module realizes the light-emitting function. The packaging component covers the light-emitting unit, and the packaging component protects the light-emitting unit so that the light-emitting unit is not damaged by external collisions. The focusing component is arranged in the packaging component to reduce the space occupied by the internal structure of the display module. The focusing component is arranged opposite to the first light-emitting portion. When the electronic device is in the anti-peeping state, the first light-emitting portion emits light and the second light-emitting portion does not emit light. The focusing component converges the light emitted by the first light-emitting portion, so that the angle of the light emitted by the display module is reduced, and then the amount of light with a large angle emitted from the periphery of the display module is reduced. People around the user cannot observe the content displayed by the display module, thereby improving the anti-peeping performance of the electronic device and enhancing the privacy of the user.

Therefore, the electronic device includes all the beneficial effects of the display module provided in any of the above technical solutions.

DETAILED DESCRIPTION

[0023] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0024] Refer to the following Figures 1 to 11 A display module 100 and an electronic device 200 according to some embodiments of the present application are described.

[0025] According to some embodiments of the present application, Figure 1 、 Figure 2 and Figure 3 As shown, a display module 100 is proposed, comprising a substrate 110, a light-emitting unit 120, a packaging component 130, and a light-collecting component 150. Multiple light-emitting units 120 are arranged in parallel on the substrate 110. Each of the light-emitting units 120 includes a first light-emitting portion 122 and a second light-emitting portion 124, with the second light-emitting portion 124 arranged around the first light-emitting portion 122. The packaging component 130 covers the light-emitting unit 120. The light-collecting component 150 is arranged within the packaging component 130, opposite the first light-emitting portion 122, and capable of converging the light emitted by the first light-emitting portion 122.

[0026] The display module 100 defined in this application is as follows: Figure 4 and Figure 5As shown, it includes a substrate 110, a light-emitting unit 120, a packaging component 130 and a focusing component 150. A plurality of light-emitting units 120 are arranged in parallel on the substrate 110, and each of the plurality of light-emitting units 120 includes a first light-emitting portion 122 and a second light-emitting portion 124. The second light-emitting portion 124 is arranged around the first light-emitting portion 122. Through the first light-emitting portion 122 and the second light-emitting portion 124, the display module 100 realizes the light-emitting function. The packaging component 130 covers the light-emitting unit 120, and the packaging component 130 protects the light-emitting unit 120 so that the light-emitting unit 120 is not damaged by external collisions. The focusing component 150 is arranged in the packaging component 130 to reduce the space occupied by the internal structure of the display module 100. The focusing component 150 is arranged opposite to the first light-emitting portion 122. When the electronic device 200 is in the anti-peeping state, the first light-emitting portion 122 emits light (such as Figure 4 and Figure 5 All the markings shown), the second light-emitting portion 124 does not emit light, and the focusing component 150 converges the light emitted by the first light-emitting portion 122, so that the angle of the light emitted by the display module 100 is reduced, and then the amount of light with a large angle emitted from the periphery of the display module 100 is reduced. People around the user cannot see the content displayed by the display module 100, thereby improving the anti-peeping performance of the electronic device 200 and enhancing the privacy of the user.

[0027] Further, if Figure 6 and Figure 7 As shown, the electronic device 200 is in a shared state, and the first light emitting portion 122 and the second light emitting portion 124 emit light at the same time (as shown in FIG. Figure 6 As shown in the A and B marking lines), the second light emitting portion 124 is arranged around the first light emitting portion 122, and the light of the second light emitting portion 124 (as shown in the A and B marking lines) is arranged around the first light emitting portion 122. Figure 6 The light emitted from the display module 100 is emitted at various angles (as shown by the B mark line), which increases the angle of light emitted by the display module 100. The user can observe the content displayed by the display module 100 at more angles, thereby improving the display effect of the display module 100 in the shared state.

[0028] Furthermore, the electronic device 200 can switch between an anti-peeping state and a sharing state, thereby improving the user experience.

[0029] Furthermore, the display module 100 defined in the present application is arranged around the first light-emitting portion 122 through the second light-emitting portion 124, and the light of the second light-emitting portion 124 is emitted from various angles of the display module 100, so that the content displayed by the display module 100 with an anti-peeping function can be observed at more angles, thereby improving the display effect of the display module 100.

[0030] Furthermore, the display module 100 defined in the present application can be switched between an anti-peeping state and a sharing state. In the anti-peeping state, the first light-emitting portion 122 is enabled to emit light, and in the sharing state, the two light-emitting portions are enabled to emit light at the same time. During use, no redundant light-emitting portions emit light, which saves energy consumption of the display module 100 and thereby increases the user's usage time.

[0031] In addition, the above embodiments provided in this application may also have the following additional technical features:

[0032] According to some embodiments of the present application, Figure 6 As shown, optionally, the packaging component 130 has a first surface 132 on the side away from the light-emitting unit 120; the orthographic projection of the first light-emitting portion 122 on the first surface 132 is a first projection 134; the orthographic projection of the focusing component 150 on the first surface 132 is a second projection 136, and the second projection 136 covers the first projection 134.

[0033] In this embodiment, a first surface 132 is provided on a side of the packaging component 130 away from the light-emitting unit 120, the orthographic projection of the first light-emitting portion 122 on the first surface 132 is a first projection 134, and the orthographic projection of the focusing component 150 on the first surface 132 is a second projection 136, which directly covers the first projection 134. This design allows the light emitted by the first light-emitting portion 122 to be more comprehensively converged through the focusing component 150, thereby reducing the angle of the light emitted from the display module 100, and thereby reducing the amount of light with a large angle emitted from the periphery of the display module 100, thereby improving the anti-peeping property of the electronic device 200 and improving the privacy of the user.

[0034] According to some embodiments of the present application, Figure 6 As shown, optionally, the orthographic projection of the second light emitting portion 124 on the first surface 132 is a third projection 138 , and the third projection 138 is staggered with the second projection 136 .

[0035] In this embodiment, the orthographic projection of the second light-emitting portion 124 on the first surface 132 is a third projection 138. The third projection 138 is staggered with the second projection 136 to prevent the focusing component 150 from affecting the light emitted by the second light-emitting portion 124, so that more light is emitted from various angles of the display module 100. The user can observe the content displayed by the display module 100 from more angles, thereby improving the display effect of the display module 100 when in a shared state.

[0036] According to some embodiments of the present application, Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, optionally, the display module 100 further includes a first shielding component 140 , which is disposed on the packaging component 130 , on a side of the focusing component 150 away from the light-emitting unit 120 , and arranged along an edge of the first projection 134 .

[0037] In this embodiment, the display module 100 also includes a first blocking component 140, which is arranged on the packaging component 130, located on the side of the focusing component 150 away from the light-emitting unit 120, and arranged along the edge of the first projection 134. The first blocking component 140 further blocks the light passing through the focusing component 150, so that the light with a larger angle after passing through the focusing component 150 is blocked by the first blocking component 140, further reducing the angle of the light emitted by the display module 100, and less light is emitted from the periphery of the display module 100, thereby improving the anti-peeping performance of the electronic device 200 and improving the privacy of the user.

[0038] According to some embodiments of the present application, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, optionally, the first shielding component 140 is an opaque metal plate 160 , and the metal plate 160 is attached to the first surface 132 .

[0039] In this embodiment, the first shielding member 140 is an opaque metal plate 160, which is attached to the first surface 132. The opaque metal plate 160 blocks light from the first light-emitting portion 122, preventing the light from passing through the first shielding member 140. This blocks more light, improving the privacy protection of the display module 100 when in the privacy protection state. Furthermore, the metal plate 160 is inexpensive and easy to manufacture, simplifying the manufacturing process of the display module 100 and enhancing the competitiveness of the electronic device 200.

[0040] Furthermore, the first shielding member 140 may be a ring-shaped, regular polygonal structure, etc., and the metal plate 160 may be a metal mask (MASK). The metal mask has the characteristics of being opaque, simple in manufacturing process, and low in cost. According to some embodiments of the present application, Figure 6 As shown, optionally, the area of ​​the surface enclosed by the inner edge of the first blocking component 140 on the first surface 132 is smaller than the area of ​​the second projection 136 .

[0041] In this embodiment, the area of ​​the surface enclosed by the inner edge of the first blocking component 140 on the first surface 132 is smaller than the area of ​​the second projection 136, so that the light with a large angle after passing through the focusing component 150 is blocked by the first blocking component 140, thereby improving the blocking effect of the focusing component 150 on the light with a large angle, further reducing the angle of the light emitted by the display module 100, and less light is emitted from the periphery of the display module 100, thereby improving the anti-peeping performance of the electronic device 200 and improving the privacy of the user.

[0042] According to some embodiments of the present application, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, optionally, the display module 100 further includes a polarizer 170 . The polarizer 170 is disposed on a side of the packaging component 130 away from the light-emitting unit 120 , adheres to the first surface 132 , and covers the first shielding component 140 .

[0043] In this embodiment, the display module 100 further includes a polarizer 170, which is disposed on the side of the packaging component 130 away from the light-emitting unit 120 and adheres to the first surface 132. The polarizer 170 covers the first shielding component 140, ensuring a stable position of the first shielding component 140 on the first surface 132. Even if the electronic device 200 is subjected to vibration, the relative position of the first shielding component 140 remains unchanged, thus further enhancing the privacy protection of the display module 100. Furthermore, the polarizer 170 (POL) provides the display module 100 with imaging capabilities.

[0044] According to some embodiments of the present application, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, optionally, the display module 100 further includes a second shielding member 142 , which is arranged around the first light-emitting portion 122 and located between the first light-emitting portion 122 and the second light-emitting portion 124 .

[0045] In this embodiment, the second shielding member 142 is arranged around the first light-emitting portion 122 to separate the first light-emitting portion 122 from the second light-emitting portion 124, thereby preventing the light emitted by the first light-emitting portion 122 and the second light-emitting portion 124 from interfering with each other and affecting the privacy protection of the display module 100.

[0046] Furthermore, the switchable anti-peeping display module 100 defined in this application has an active-matrix organic light-emitting diode (AMOLED) display structure, which divides the three primary color pixels (red, green, and blue) into sub-pixels with a first internal light-emitting portion 122 and a second external light-emitting portion 124, each of which is independently controlled by the display module 100. Specifically, the division of the three primary color pixels (red, green, and blue) into the first internal light-emitting portion 122 and the second external light-emitting portion 124 is achieved by shielding the evaporation with a metal mask. That is, the metal mask is provided around the first light-emitting portion 122 to provide additional shielding to achieve the division. This ensures that no light-emitting material is deposited during evaporation, preventing the light emitted by the first light-emitting portion 122 and the second light-emitting portion 124 from interfering with each other, thereby enhancing the anti-peeping performance of the display module 100. The first light emitting portion 122 and the second light emitting portion 124 can be divided arbitrarily, and the divided first light emitting portion 122 and the second light emitting portion 124 can be of any shape.

[0047] Further, if Figure 3 and Figure 11 As shown, the metal mask is very precisely designed, featuring high precision and strong stability. It can be designed into any shape, allowing for circular, elliptical, or polygonal segmentation of the first and second light-emitting portions 122, 124. Any shape, such as a diamond, rectangle, or square, can be created. The metal mask serves as the second shielding member 142 between the first and second light-emitting portions 122, 124, achieving precise pattern positioning of the first and second light-emitting portions 122, 124.

[0048] According to some embodiments of the present application, Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, optionally, the focusing component 150 is a lens 180 , and the refractive index of the lens 180 is greater than the refractive index of the packaging component 130 .

[0049] In this embodiment, the focusing component 150 is a lens 180, which can be a microlens 180, which has the function of refracting light and has a refractive index greater than that of the surrounding medium, so that the divergent light reflected by the first light-emitting portion 122 is converged for the first time through the lens 180, so that the angle of the light emitted by the display module 100 is reduced, and then the amount of light with a large angle emitted from the periphery of the display module 100 is reduced, thereby improving the anti-peeping performance of the electronic device 200.

[0050] According to some embodiments of the present application, Figure 10As shown, an electronic device 200 is proposed. The electronic device 200 includes the display module 100 provided in any of the above embodiments. Therefore, the electronic device 200 includes all the beneficial effects of the display module 100 provided in any of the above embodiments.

[0051] In addition, the above embodiments provided in this application may also have the following additional technical features:

[0052] According to some embodiments of the present application, Figure 8 、 Figure 9 and Figure 10 As shown, optionally, the electronic device 200 further includes a first electrode 210, a second electrode 220, and a control module 230. The first electrode 210 is electrically connected to the first light-emitting portion 122; the second electrode 220 is electrically connected to the second light-emitting portion 124; and the control module 230 is electrically connected to the first electrode 210 and the second electrode 220, respectively. When the electronic device 200 is in the anti-peeping mode, the control module 230 controls the first light-emitting portion 122 to emit light and controls the second light-emitting portion 124 not to emit light through the first electrode 210; when the electronic device 200 is in the sharing mode, the control module 230 controls the first light-emitting portion 122 to emit light through the first electrode 210, and controls the second light-emitting portion 124 to emit light through the second electrode 220.

[0053] In this embodiment, the electronic device 200 further includes a first electrode 210, a second electrode 220, and a control module 230. The first electrode 210 is electrically connected to the first light-emitting portion 122, and the second electrode 220 is electrically connected to the second light-emitting portion 124. The control module 230 controls the first electrode 210 and the second electrode 220, respectively, thereby controlling the first light-emitting portion 122 and the second light-emitting portion 124 to emit light.

[0054] Further, if Figure 9 As shown, when the electronic device 200 is in the anti-peeping state, the first light-emitting portion 122 emits light, and the second light-emitting portion 124 does not emit light. The focusing component 150 converges the light emitted by the first light-emitting portion 122, and then further blocks the light with a large angle through the first shielding component 140, so that the angle of the light emitted by the display module 100 is reduced, thereby improving the anti-peeping performance of the electronic device 200 and improving the privacy of the user. Specifically, the focusing component 150 converges the light emitted by the first light-emitting portion 122, and then further blocks the light with a large angle through the first shielding component 140, and the visible range that can be observed by the human eye 240 (such as Figure 9 As shown, E is the visible range) is smaller, which improves the anti-peeping performance of the electronic device 200.

[0055] Further, if Figure 8As shown, when the electronic device 200 is in a shared state, the first light-emitting portion 122 and the second light-emitting portion 124 emit light at the same time. The second light-emitting portion 124 is arranged around the first light-emitting portion 122. The light emitted by the second light-emitting portion 124 is emitted at various angles, which increases the angle of the light emitted by the display module 100. The user can observe the content displayed by the display module 100 at more angles, thereby improving the display effect of the display module 100 in a shared state. Specifically, the light emitted by the second light-emitting portion 124 at various angles increases the angle of the light emitted by the display module 100. The human eye 240 can observe the content displayed by the display module 100 at more angles, and the visual range (such as Figure 8 As shown, D is the visible range) is larger, thereby improving the display effect of the display module 100 in the shared state.

[0056] Specifically, the electronic equipment defined in this application is also applicable to other display structures such as liquid crystal display (LCD), sub-millimeter light emitting diode (MiniLED, Mini Light Emitting Display) display, micro light emitting diode (MicroLED, Micro Light Emitting Display) display, etc. In addition to being used in the field of smart phones, it is also applicable to electronic products such as tablets, notebooks, smart watches, car displays, refrigerator displays, and televisions.
