Description

Technical Field

[0001] This utility model relates to the field of display technology, and in particular to a display component and a mobile phone case with a screen. Background Technology

[0002] With the expansion of smartphone functions and the increasing demand for personalization, phone cases with screens have gradually become a market hotspot. These phone cases integrate electronic displays (such as LCD or e-ink screens) on the back of the case, which can display information such as time and custom patterns, significantly improving the versatility of the phone case.

[0003] Existing displays typically require two ports connected to the circuit board. These two ports are separate, with one dedicated to power supply and the other for data signal transmission. This separation reduces power supply noise interference and ensures screen display stability. However, connecting the circuit board to the other port requires crossing a portion of the display screen, which is usually located in the center of the phone case. This causes the electrical connection between the display screen and the circuit board to overlap with the phone's wireless charging device located on the phone case. When the phone with the screen is wirelessly charging, if the connection is located in the magnetic field area of ​​the wireless charging coil (especially the center of the magnetic field), the conductive material will experience eddy currents due to the alternating magnetic field, affecting the phone's wireless charging function. This results in electromagnetic interference and energy loss, hindering wireless charging. Therefore, improvements are urgently needed. Utility Model Content

[0028] The solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. In addition, the descriptions involving "first," "second," etc., in this utility model are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0029] To address the technical deficiencies in related technologies, this utility model provides a display screen assembly. Please refer to [link / reference]. Figures 1 to 4The display assembly includes an e-ink screen 100 and a circuit board 200. The e-ink screen 100 includes a central display area 110 and a peripheral non-display area 120. The central display area 110 is used to display images, and the peripheral non-display area 120 is provided with two connection ports 121, which are symmetrically arranged. One connection port 121 is dedicated to power supply, and the other connection port 121 is used to transmit data signals. This separate and symmetrical arrangement design can reduce the interference of power supply noise on signals and ensure the stability of the display in the central display area 110. In addition, if the e-ink screen 100 requires different voltages (e.g., 3.3V for the main control chip and 5V for the backlight), the two connection ports 121 can independently allocate power, thereby avoiding voltage fluctuations.

[0030] It should be noted that ink capsule molecules are disposed within the central display area 110. These ink capsule molecules can be pushed to different positions under the control of positive and negative charges, thereby presenting different images. Specifically, under the control of the circuit board 200, when the current stops, the ink capsule molecules remain fixed in their current positions. With this configuration, the display of the e-ink screen 100 does not require power, significantly reducing the energy consumption of the e-ink screen 100.

[0031] Furthermore, the circuit board 200 has at least one connection portion 210 overlapping with the two wiring ports 121. This connection portion 210 can be an electrical circuit formed by the main body of the circuit board 200, or it can be formed by an external ribbon cable; no specific limitation is made here. Specifically, the connection portion 210 is electrically connected to the two wiring ports 121 respectively. The connection portion 210 is provided with a clearance portion 230, which avoids the central display area 110. With this configuration, the clearance portion 230 can avoid the central display area 110 of the e-ink screen 100, which is generally located in the middle of the phone case. Similarly, the middle of the phone, when fitted with the phone case, is the wireless charging sensing area. This allows the connection portion 210 to avoid the phone's wireless charging device, reducing electromagnetic interference and energy loss to the wireless charging coil when the phone is charging.

[0032] Through the above technical solution, the display screen of this utility model is provided with a central display area 110 and a peripheral non-display area 120. Two wiring ports 121 are located on the peripheral non-display area 120. The connection part 210 of the circuit board 200 is connected to the two wiring terminals. The connection part 210 is provided with a clearance part 230 that avoids the central display area 110. With this configuration, when the display screen assembly is located in the middle of the mobile phone case, the connection part 210 connected to the wiring terminals can avoid the wireless charging area of ​​the mobile phone. This can prevent electromagnetic interference between the mobile phone and the connection part 210 during wireless charging, thereby avoiding energy loss during charging. At the same time, it can also prevent local heat generation during wireless charging, which could affect the safety of the mobile phone device.

[0033] It should be noted that the shape of the connecting part 210 and the shape of the avoidance part 230 can be adapted to the outer contour of the e-ink screen 100. For example, when the e-ink screen 100 is square, the shape of the connecting part 210 can be a square ring structure, and the empty area inside the ring is the avoidance part 230; the shape of the connecting part 210 can also be arranged around the periphery of the square e-ink screen 100 to form a right-angled shape structure, and the avoidance part 230 is the inner area of ​​the right-angled structure; in some embodiments, the e-ink screen 100 is circular.

[0034] Please see Figure 1 In one embodiment, the outer contour of the connecting portion 210 is provided with an arc-shaped structure, and the concave part of the arc-shaped structure forms a clearance portion 230. In this case, in order to reduce the size of the display assembly, the connecting portion 210 may partially overlap with the central display area 110, and the arc-shaped protrusion of the connecting portion 210 is provided adjacent to the outer contour of the e-ink screen 100 to increase the area of ​​the arc-shaped concave part, thereby increasing the area of ​​the clearance portion 230.

[0035] Please see Figure 2 In other embodiments, the outer contour of the connecting portion 210 is arranged in a ring structure, and the inner contour of the ring structure forms a clearance portion 230. The connecting portion 210 adopts a ring structure, and the design of a single connecting portion 210 divided into two lines, with the ring structure set close to the peripheral non-display area 120, can reduce the overlap area between the connecting portion 210 and the central display area 110, increase the area of ​​the inner contour of the ring structure, and thus increase the area of ​​the clearance portion 230.

[0036] Please see Figure 3 In some other embodiments, the connecting part 210 is located on the periphery of the e-ink screen 100. Within the allowable installation space of the display assembly, the connecting part 210 being located on the periphery of the e-ink screen 100 can completely avoid the wireless charging device on the mobile phone, thus minimizing energy loss.

[0037] Considering that the circuit board 200 is a rigid plate, while the mobile phone case is generally a flexible shell 400, in this embodiment, the circuit board 200 includes a main component board 220 and a ribbon cable. The main component board 220 is electrically connected to the e-ink screen 100 via the ribbon cable, which forms a connection portion 210. This reduces the area of ​​the circuit board 200. When the mobile phone case deforms, the connection between the ribbon cable and the two connection ports 121 is more reliable and stable because the ribbon cable is made of a soft material.

[0038] Furthermore, in some embodiments, the extension lines of the two connection ports 121 are set at a 45° angle to the horizontal direction. This tilted arrangement of the two connection ports 121 reserves areas at the top and bottom of the e-ink screen 100, preventing interference with other parts of the phone case (such as the camera cutout) after the display assembly is installed inside the phone case.

[0039] Please see Figures 5 to 6 This utility model also provides a phone case with a screen, comprising a housing 400 and a display screen assembly. The housing 400 has a mounting cavity adapted to the phone and a mounting groove 410 disposed opposite to the mounting cavity. The display screen assembly is disposed within the mounting groove 410. A clearance portion 230 avoids the wireless charging device of the phone mounted on the housing 400. A sealing plate 500 covers the mounting groove 410. With this configuration, when the phone is wirelessly charged after being fitted onto the housing 400 with the display screen assembly, the clearance portion 230 in the area of ​​the magnetic field of the wireless charging coil in the connecting portion 210 can avoid the wireless charging area, thereby avoiding electromagnetic interference that could affect wireless charging. In addition, the sealing plate 500 can enclose the display screen assembly in the mounting groove 410, preventing it from detaching from the mounting groove 410.

[0040] Furthermore, considering that the e-ink screen 100 needs to be powered when displaying images and interacting with external devices, in order to facilitate the power supply of the e-ink screen 100 by the screen-equipped phone case, in this embodiment, the display assembly also includes a near-field communication panel 300. The near-field communication panel 300 draws power from the phone through radio magnetic field transmission. The near-field communication panel 300 is electrically connected to the circuit board 200, and the circuit board 200 is electrically connected to the e-ink screen 100, thereby providing power and screen display signals to the e-ink screen 100.

[0041] It should be noted that the near-field communication panel 300 is a short-range, high-frequency radio technology that allows electronic devices to perform contactless point-to-point data transmission at very close range and to exchange power. In this embodiment, when a smartphone is in close contact with the near-field communication panel 300, the smartphone emits radio signals, forming an electromagnetic field. The near-field communication panel 300 then senses the energy in the electromagnetic field through its receiving coil and converts it into electrical energy to power itself. With this configuration, the near-field communication panel 300 in this embodiment can achieve power transmission without a physical connection interface, and it can also provide power to the e-ink screen 100, greatly improving the ease of use of the screen-equipped phone case.

[0042] In this embodiment, the near-field communication panel 300 is positioned near the edge of the housing 400. Since the antenna of a typical smartphone is located on the side of the phone, positioning the near-field communication panel 300 at the edge of the housing 400 facilitates power extraction.

[0043] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
