[0050] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0051] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure.

It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0052] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0053] In related art, data lines extending from a display panel of a display device are typically bent along the edge of the display panel and connected to a circuit board located away from the display side of the display panel. Data signals are then transmitted to each sub-pixel within the display panel via the circuit board and the data lines. In other words, the circuit board and the display panel are essentially stacked in the thickness direction of the display device, which increases the thickness of the display device and reduces its aesthetics.

[0054] Based on the technical problems existing in related technologies, such as Figure 1 As shown, the present disclosure provides a display device 100, such as Figure 1 As shown, the display device 100 may include a display panel 1, which may include a display body 11 and a plurality of signal transmission films 12 electrically connected to one side edge of the display body 11. Each signal transmission film 12 may be electrically connected to a data line inside the display body 11 so as to subsequently transmit a control signal to the display body 11 through the signal transmission film 12. In a direction parallel to the side edge connected to the signal transmission film 12, the plurality of signal transmission films 12 may be arranged at intervals, and each signal transmission film 12 may transmit a control signal to the display body 11. Compared with the case where only one signal transmission film is set, the amount of signal transmitted by each signal transmission film can be reduced. In particular, when the size of the display device 100 in the direction in which the plurality of signal transmission films 12 are arranged side by side is relatively large, the workload of each signal transmission film 12 can be greatly reduced.

[0055] Furthermore, the display device 100 may also include a first circuit board 2, which can be electrically connected to each signal transmission film 12, and the first circuit board 2 and multiple signal transmission films 12 are located on the same side of the display body 11. Subsequently, the first circuit board 2 can also be connected to the main board of the display device 100, so that the first circuit board 2 can transmit control signals to the display body 11 through the signal transmission film 12 to control the picture display of the display body 11.

[0056] Compared to related art, the first circuit board 2 and the signal transmission film 12 in the present disclosure are both disposed on the same side edge of the display body 11. This allows the thickness of the display device 100 to be reduced by increasing its length, thereby contributing to a lighter and thinner display device 100 and improving its appearance. The signal transmission film 12 may include a chip-on-film (COF), on which a control chip may be packaged using a COF process. The control signals transmitted by the first circuit board 2 may be transmitted via the control chip and the COF to signal lines within the display body 11. These signal lines may include gate lines and data lines.

[0057] like Figure 1 As shown in , the display device 100 may include two first circuit boards 2, and each first circuit board 21 may be electrically connected to a plurality of signal transmission films 12, thereby reducing the amount of signal transmitted by each first circuit board 2. In particular, when the display device 100 is relatively large in the direction in which the plurality of signal transmission films 12 are arranged side by side, the workload of each first circuit board 2 can be greatly reduced by connecting the plurality of first circuit boards 2 to the plurality of signal transmission films 12. At the same time, compared with the case of using a whole circuit board, the strength of each first circuit board 2 can be improved, and the impact resistance of each first circuit board 2 can be improved. Of course, in other embodiments, the display device 100 may include a single first circuit board 2, which is electrically connected to a plurality of signal transmission films 12; or, in some other embodiments, each first circuit board 2 may also be connected to a single signal transmission film 12. The specific design can be based on the length of the display device 100, and the present disclosure does not limit this. Among them, the display body 11 can include a transparent OLED display body, which uses the self-luminous characteristics of the transparent OLED display body to realize image display. Moreover, the self-luminous characteristics of the OLED transparent display body can avoid setting up a backlight source, which is conducive to realizing transparent display of the display device 100.

[0058] Furthermore, the display device 100 may also include a main frame 3, a protective layer 4, a first conductive layer, and a metal reinforcement bracket 7. The protective layer 4 may include a transparent cover glass to protect the display panel 1 while avoiding obstruction of the image. The main frame 3 and the first circuit board 2 may be arranged along the thickness direction of the display device 100. The first conductive layer may be attached to the first circuit board 2, specifically connected to the back surface of the first circuit board 2. The first conductive layer may further contact the conductive area of ​​the main frame 3, thereby providing electrostatic protection for the first circuit board 2.

[0059] Among them, the first conductive layer may include a conductive cloth 51, a first conductive foam 52 and a second conductive foam 53. The conductive cloth 51 can be attached to the back of the first circuit board 2 (opposite to the front side connected to the data line drawn from the display body 11), and the first conductive foam 52 is arranged on the side of the display body 11 close to the main frame 3. It can contact the conductive cloth 51 and the conductive area on the main frame 3 respectively, forming an electrostatic discharge path from the first circuit board 2-conductive cloth 51-first conductive foam 52-main frame 3; at the same time, the metal reinforcement bracket 7 can It is arranged on the side of the first circuit board 2 away from the conductive cloth 51. The first circuit board 2 is located between the metal reinforcement bracket 7 and the main frame 3. The second conductive foam 53 can contact the first conductive foam 52. At the same time, the second conductive foam 53 can be bent along the edge of the display panel 1 and contact the conductive area of ​​the metal reinforcement bracket 7, thereby forming an electrostatic discharge path of the first circuit board 2-conductive cloth 51-first conductive foam 52-second conductive foam 53-metal reinforcement bracket 7, so that static electricity can be discharged respectively through the main frame 3 and the metal reinforcement bracket 7. Among them, the first conductive foam 52 can be used to pad the thick conductive cloth 51 toward the main frame 3, filling the gap between the conductive cloth 51 and the main frame 3 to achieve conduction, so as to be compatible with the settings of other components in the main frame 3 and avoid making the main frame 3 thicker. By bending the second conductive foam 53, the first conductive foam 52 located on the back of the first circuit board 2 can be connected to the metal reinforcement bracket 7 located on the front of the first circuit board 2, thereby achieving multi-path discharge of static electricity. Of course, in other embodiments, the first conductive layer may also only include the first conductive foam 51, a portion of the first conductive foam 51 is in contact with the conductive area of ​​the main frame 3, and the other portion can extend toward the metal reinforcement bracket 7 and contact the metal reinforcement bracket 7. The present disclosure does not limit this.

[0060] The main frame 3 may include a metal main frame to increase the contact area with the ground and enhance the electrostatic protection effect; alternatively, the main frame 3 may include a plastic main frame. In this case, a conductive layer may be formed on the plastic main frame by spraying conductive paint or adhering a metal layer. Compared with the method of using a metal main frame for the main frame 3, the temperature rise caused by heat from the first circuit board 2 and conduction can be reduced. Similarly, the main frame 3 may also include a metal main frame, for example, a steel bracket or an aluminum bracket, to enhance the strength of the entire device.

[0061] In the above embodiment, the first circuit board 2 may include a circuit board body 21 and a first insulating layer 22. The first insulating layer 22 may be formed on the back of the circuit board body 21, and the front of the circuit board body 21 may be connected to the secondary signal transmission film 12. The first insulating layer 22 may provide insulation protection for the first circuit board 2, especially when an insulating varnish is formed on the back of the circuit board body 21, providing double insulation protection. To provide electrostatic protection for the first circuit board 2, a conductive fabric 51 may be attached to the side of the first insulating layer 22 away from the circuit board body 21. Alternatively, in other embodiments, the conductive fabric 51 may be connected to the exposed copper area of ​​the circuit board body 21, although this disclosure is not limited thereto.

[0062] It is understandable that the display body 11 is covered with data lines, and each sub-pixel is controlled by the signal transmitted by the data lines. Therefore, it is inevitable that static electricity may also be generated on the edge of the display body 11 other than the edge extending into the main frame 3. Figure 1 As shown, the display device 100 may further include a side frame 8 and a third conductive foam 9, as shown in FIG. Figure 2 As shown, the side frame 8 may include a first portion 81 and a second portion 82, which are substantially vertically connected. The first portion 81 is attached to the protective layer 4, and the first portion 81 and the display body 11 are attached to the same side of the protective layer 4. The first portion 81 is disposed close to the display body 11. The third conductive foam 9 may contact the conductive areas of the side frame 8 and the main frame 3, respectively, thereby forming an electrostatic discharge path of the display body 11-first portion 81-third conductive foam 9-main frame 3, thereby providing electrostatic protection for the display body 11. The second portion 82 may be attached to a side surface of the protective layer 4 that is parallel to the thickness direction of the protective layer 4, thereby protecting the protective layer 4 through the second portion 82.

[0063] Based on the above embodiments, Figure 3As shown, to support the display device 100, the display device 100 may further include a base 10, a display control board 111, and a first cable 112. The base 10 may include a first accommodating cavity 101 and a through-groove 102 recessed inward from the surface of the base 10 and connected to the first accommodating cavity 101. A portion of the main frame 3 and the first circuit board 2 are disposed within the through-groove 102, and the sidewalls of the through-groove 102 and the protective layer 4 may be locked together using a locking member. The display control board 111 may be disposed within the first accommodating cavity 101, and one end of the first cable 112 may be connected to the first circuit board 2. After exiting the first circuit board 2, the first cable 112 may be bent along the edge of the through-groove 102 that connects to the first accommodating cavity 101, and then connected to the display control board 111. Timing signals may be transmitted to the first circuit board 2 via the display control board 111. Furthermore, the first wiring 112 may include a data line body (not shown) and a shielding insulation layer (not shown) covering the data line body. The shielding insulation layer may provide shielding and insulation protection for the covered data line body.

[0064] The display device 100 may further include a main board 113 and a second conductive layer (not shown) disposed in the first accommodating cavity 101. The main board 113 may be electrically connected to the display control board 111, so that a control signal may be sent to the display control board 111 via the main board 113 and then transmitted to the first circuit board 2 via the first cable 112, thereby controlling the display body 11 to display. The main board 113 and the display control board 111 may be arranged sequentially along the thickness direction of the base 10. Thus, the first cable 111 may be bent and led out from the through-groove 102 and may extend upward along the sidewalls surrounding the through-groove 102, and then bend into the first accommodating space 101 to connect to the display control board 111, thereby making the first cables 112 neatly arranged. The display device 100 may include a plurality of first cables 112 arranged side by side, and each first cable 112 may be connected to one or more first circuit boards 2. The specific design may be as needed, and the present disclosure is not limited thereto. Among them, the display control board 111 can be a logic board, which can convert the digital signal received from the main board 113 into a row and column drive signal to drive the display panel 1 for display. At the same time, the display control board 111 can also form a row drive voltage and a column drive voltage in the display body 11, and can also form the turn-on voltage of the thin film transistor in the display body 11, or other voltages required in the display body 11.

[0065] Specifically, the display control panel 111 may include contacts 1111, such as Figure 4 As shown, the contact 1111 can be arranged toward the bottom surface of the base 10, and the contact 111 can be located at one end of the display control board 1111 close to the through slot 102, thereby reducing the extension length of the first cable 112. In another embodiment, as Figure 5 As shown, the contact 1111 can also be arranged toward the top surface of the base 10, that is, toward the fixed portion of the display panel 1, and the contact 111 can also be located at the end of the display control board 1111 away from the through slot 102. In this case, the first cable 112 can pass through from above or below the display control board 11 and then bend to connect with the contact 1111. In another embodiment, as Figure 6 As shown, Figure 6 The embodiment is relatively Figure 5 In the embodiment, the display control board 111 can be arranged closer to the bottom surface of the base 10, and the specific arrangement can be selected according to the parts layout in the base 10. The specific arrangement of the display control board 111 and the bottom surface of the base 10 is not limited by the present disclosure. Of course, in some other embodiments, the contact 1111 can be arranged toward the bottom surface of the base 10, and the contact 111 can also be located at the end of the display control board 1111 away from the through slot 102. The connection can be achieved by bending the first row of cables 112 and designing the length of the first row of cables 112. Of course, it is also possible that the contact 1111 can also be arranged toward the top surface of the base 10, and the contact 111 can be located at the end of the display control board 1111 close to the through slot 102. For specific connection methods, please refer to Figure 4-Figure 6 The embodiments of the present invention will not be described in detail here.

[0066] Furthermore, since the display control board 111 is close to the main board 113, to avoid signal interference between the first cable 112 and the main board 113, the first cable 112 can be bonded to the sidewalls of the through-slot 102 via a second conductive layer to prevent the first cable 112 from bending toward the main board 113. Specifically, the second conductive layer 10 and the sidewalls of the through-slot 102 can be bonded together, and the second conductive layer 10 and the first cable 112 can be bonded together using double-sided tape. This allows static electricity generated by the first cable 112 to be discharged through the base 10, which also helps to improve the neatness of the wiring layout within the base 10. Of course, in other embodiments, after bending out of the through-slot 102, the first cable 112 can also extend obliquely along the through-slot 102 toward the surface of the first accommodating cavity 101, or extend obliquely within the first accommodating cavity 101. This is not limited in this disclosure.

[0067] The base 10 may be a split structure, such as Figure 1As shown, the base 10 may include a first base, a second base, and a bottom plate. The first base and the second base may be assembled to form a through-groove 102. The transparent display layer 1 and a portion of the protective layer 4 are both disposed within the through-groove 102. The first base and the second base are further connected to the bottom plate to form a first accommodating cavity 101. Subsequently, after the first base or the second base is connected to the display panel 1, the first cable 112 may extend from an opening in the first base or the second base into the first accommodating cavity 101. The opening may connect the through-groove 102 and the first accommodating cavity 101. Alternatively, in other embodiments, the base 10 may also be an integrated structure, and may be a metal base or a plastic base with a conductive layer.

[0068] The display device 100 may further include a cover plate 114, which may be assembled with the base 10 to seal the first accommodating cavity 101, thereby protecting the electronic components in the first accommodating cavity 101. In addition, in the stacked display control board 111 and the main board 113, the display control board 111 is closer to the cover plate 114 than the main board 113, so as to avoid the first cable 112 from contacting the cover plate 114 during the process of connecting to the display control board 111, thereby preventing the first cable 112 from contacting the cover plate 114 and causing damage. In order to prevent the first cables 112 from contacting the cover plate 114, a barrier layer (not shown) may be provided on the side of the cover plate 114 facing the interior of the first accommodating cavity 101. When the deformation of the first cables 112 toward the cover plate 114 is relatively large, the barrier layer may contact and press against the first cables 112 to prevent the first cables 112 from contacting the cover plate 114. Of course, when the deformation of the first cables 112 is relatively small, the barrier layer may not contact the first cables 112 and only serve to prevent the first cables 112 from contacting the cover plate 114. The barrier layer 112 may include foam and its height in the height direction of the base 10 may be greater than or equal to 15 mm to prevent the first cables 112 from bending and deforming toward the cover plate 114 and causing contact when the distance is too small.

[0069] The display control board 111 can be directly connected to the main board 113. Alternatively, in the embodiment provided by the present disclosure, the display device 100 can further include a second cable 115, one end of which is conveniently connected to the display control board 111 and the other end can be connected to the main board 113. The second cable 115 can include a shielding insulation layer, which can achieve a shielding effect through the shielding insulation layer and prevent short circuits through the insulation effect. The main board 113 can include a metal plate 1131 and a main board body 1132. The metal plate 1131 can be connected to the base 10, which can be connected to the bottom surface of the base 10, or the metal plate 1131 can be connected to the middle of the first accommodating cavity 101, and a support can be formed from the bottom to the top on the bottom surface of the base 10 to support the metal plate 1131 and reduce the probability of the metal plate 1131 collapsing or deforming. The main board 1132 is mounted on the metal plate 1131, and the display control board 1132 is mounted on the main board 1132. After the second cable 115 is connected to the display control board 1132, it can be bent downward and connected to the side of the main board 1132 facing the metal plate 1131, thus creating a static discharge path from the second cable 115 to the metal plate 1131 and then to the base 10. Of course, to ensure electrical continuity, a gap is made in the insulating shielding layer of the second cable 115, leaving the conductive layer exposed.

[0070] Furthermore, multiple logic interfaces can be provided on the main board body 1132. The display device 100 can also include a baffle 116, which can be assembled with the base 10, and multiple logic interfaces can be exposed through the baffle 116 to electrically connect the display device 100 to external data lines. The baffle 116 can be connected to the metal plate 1131 via a metal fastener, thereby further connecting the metal plate 1131 to the baffle 116 via the metal fastener. The baffle 115 can be made of a metal material to achieve electrical conductivity. Alternatively, the baffle 116 can include a plastic baffle and a conductive layer on one or more surfaces of the plastic baffle. The conductive layer can be formed by conductive paint formed on one or more surfaces of the plastic baffle, so as to facilitate electrical conductivity of structures such as the metal plate 1131 and provide electrostatic protection for the logic interfaces and the main board 113. Specifically, a conductive paint of more than 5 mm can be sprayed on the plastic baffle to form a conductive layer to ensure good conductivity.

[0071] In the embodiment of the present application, the display control board 111, the first cable 112, the main board 113, the second cable 115, etc. are all arranged in the base 10, which can avoid arranging electronic components on the back of the display panel 1, which is conducive to realizing transparent display of the display panel 1 and at the same time facilitating the thinness and lightness of the display device 100.
