Description

Technical Field

[0001] The present application relates to the field of display screen testing, and in particular to a display screen assembly, a display, and an electronic device. Background Art

[0002] At present, organic light-emitting diode display panels (non-flexible) and liquid crystal display panels mostly use glass substrates as the base substrate. In the production process of display panels and display modules, it is difficult to avoid bumps and collisions, which easily cause glass damage, such as cracks, edge collapse or corner collapse. In addition, the cable on the display panel can be plugged in and out, but it is impossible to determine whether it is plugged in and out properly. Summary of the invention

[0003] In view of this, the present application provides a display screen assembly, a display and an electronic device, which can solve the above-mentioned technical problems.

[0004] In a first aspect, an embodiment of the present application provides a display screen assembly, comprising a processor, a first circuit board, a first flexible connector and a display panel; the processor is arranged on the first circuit board, and the first circuit board and the display panel are pluggably connected through the first flexible connector; the display panel comprises a display area and a non-display area; the display screen assembly also comprises an annular conductive wire arranged in the non-display area, the annular conductive wire surrounds the display area, and a first detection point and a second detection point are provided on the annular conductive wire; the display screen assembly also comprises a first conductive connection wire and a second conductive connection wire arranged along the surface of the first circuit board and the first flexible connector, the two ends of the first conductive connection wire are respectively connected to the first detection point and the processor, and the second conductive connection wire is respectively connected to the second detection point and the processor; the second conductive connection wire is grounded; the processor is used to determine the hardware status of the display screen assembly according to the voltage of the first circuit board to the ground.

[0005] Thus, the annular conductive wire surrounds the non-display area of ​​the display panel. If the four sides of the display panel are damaged, the annular conductive wire will form an open circuit. The first conductive connection line and the second conductive connection line are on the surface of the first circuit board and the first flexible connection member. When the first flexible connection member is not plugged in, the first conductive connection line or the second conductive connection line at the corresponding position will form an open circuit. Therefore, the on and off of the annular conductive wire, the first conductive connection line and the second conductive connection line will affect the resistance in the entire circuit, thereby affecting the voltage of the first circuit board to the ground. Therefore, the processor can determine the hardware status of the display screen assembly based on the voltage of the first circuit board to the ground. Thus, it is possible to detect whether the first flexible connection member is plugged in while detecting whether the display screen assembly is damaged, thereby simplifying the detection process.

[0006] Preferably, the annular conductive wire, the first conductive connecting wire and the second conductive connecting wire are all metal conductive wires.

[0007] Therefore, the annular conductive wire, the first conductive connecting wire and the second conductive connecting wire can be conductive when the display screen assembly is not damaged, which is convenient for detection and has low material cost, thereby achieving the detection purpose and reducing the detection cost.

[0008] Preferably, the display screen assembly also includes a second circuit board and a second flexible connector, one end of the first flexible connector is connected to the first circuit board, and the other end is pluggably connected to the first end of the second circuit board, the other end of the second circuit board is connected to the display panel through the second flexible connector, and the first conductive connecting line and the second conductive connecting line are sequentially arranged on the second circuit board and the second flexible connector to form a conductive loop.

[0009] Thus, the first flexible connector is pluggable and connected to the second circuit board, and the second circuit board is connected to the display panel through the second flexible connector. This can reduce the possibility of damage to the display panel caused by plugging and unplugging the first flexible connector, and can better protect the display panel.

[0010] Preferably, the second flexible connection member is one of a chip-on-film, a chip-on-glass and a flexible printed circuit board.

[0011] Therefore, the second flexible connecting member can be made of different materials, which has a wider range of choices and brings convenience to actual processing.

[0012] Preferably, there are two of each of the first flexible connector, the second circuit board and the second flexible connector; the two second circuit boards are arranged side by side on the side of the display panel close to the first circuit board and are located between the display panel and the first circuit board; the two second flexible connectors are arranged side by side on the side of the display panel close to the first circuit board and are located between the display panel and the two second circuit boards; each second flexible connector is arranged corresponding to one second circuit board and connected between the display panel and the corresponding second circuit board; the two first flexible connectors are arranged side by side between the two second circuit boards and the first circuit board, and each first flexible connector is correspondingly connected to the second circuit board in a pluggable manner; the first conductive connecting line is arranged on one of the first flexible connectors, the corresponding second circuit board and the corresponding second flexible connector, and the second conductive connecting line is arranged on another one of the first flexible connectors, the corresponding second circuit board and the corresponding second flexible connector to form a conductive loop.

[0013] Thus, the first conductive connection line and the second conductive connection line are used to respectively detect the reliability of the connection between the two first flexible connectors and the corresponding second circuit boards.

[0014] Preferably, the first detection point and the second detection point divide the annular conductive line into a first line segment and a second line segment, the first line segment has a first resistor, the second line segment has a second resistor, the first resistor is different from the second resistor, the resistance of the first circuit board to ground is a third resistor, and the voltage of the first circuit board to ground is the voltage across the third resistor.

[0015] Therefore, the first resistor and the second resistor are different, and this difference can be reflected in the voltage across the third resistor, and then the hardware condition of the display screen assembly can be judged by the difference in the voltage across the third resistor.

[0016] Preferably, under different hardware states, the voltage across the third resistor is determined by at least one resistance value of the first resistor, the second resistor and the third resistor, and the different voltages across the third resistor are used to represent different hardware states of the display screen assembly, and the hardware state includes one of normal and abnormal.

[0017] Therefore, different hardware states of the display screen assembly are determined according to the difference in voltage across the third resistor.

[0018] Preferably, when the voltage across the third resistor is determined by the second resistor and the third resistor, it is determined that the hardware state is abnormal and the abnormal state is that the first line segment is disconnected; or,

[0019] When the voltage across the third resistor is determined by the first resistor and the third resistor, it is determined that the hardware state is abnormal and the abnormal state is that the second line segment is disconnected; or,

[0020] When the voltage across the third resistor is zero, it is determined that the hardware state is abnormal and the abnormal state is that the first conductive connection line and / or the second conductive connection line is disconnected; or,

[0021] When the voltage across the third resistor is determined by the first resistor, the second resistor and the third resistor, it is determined that the hardware state is normal.

[0022] Therefore, based on the difference in voltage across the third resistor, it is determined whether the first line segment is disconnected, the second line segment is disconnected, or the first conductive connection line and / or the second conductive connection line is disconnected, thereby determining different hardware states of the display screen assembly.

[0023] In a second aspect, an embodiment of the present application provides a display comprising a backlight module and the above-mentioned display screen assembly.

[0024] Therefore, a display having the display screen assembly can detect whether the display screen assembly is damaged while detecting whether the first flexible connector is plugged in place, thereby simplifying the detection process.

[0025] In a third aspect, an electronic device provided by an embodiment of the present application includes a housing and the above-mentioned display.

[0026] Therefore, the electronic device with the display can detect whether the display screen assembly is damaged while detecting whether the first flexible connector is plugged in place, thereby simplifying the detection process. BRIEF DESCRIPTION OF THE DRAWINGS

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0060] Please refer to Figure 1 , Figure 1 Schematic diagram of a module of a display screen assembly in the first embodiment of the present application. The display screen assembly 100 includes a processor 10, a first circuit board 20, a first flexible connector 30 and a display panel 40. The processor 10 is arranged on the first circuit board 20. The first circuit board 20 and the display panel 40 are pluggably connected through the first flexible connector 30. The display panel 40 includes a display area 41 and a non-display area 42. The non-display area 42 is arranged around the display area 41. The display screen assembly 100 also includes a ring-shaped conductive line 43 arranged in the non-display area 42, and the ring-shaped conductive line 43 surrounds the display area 41. The ring-shaped conductive line 43 is provided with a first detection point 431 and a second detection point 432. The display screen assembly 100 also includes a first conductive connection line 51 and a second conductive connection line 52 arranged along the surface of the first circuit board 20 and the first flexible connector 30. The two ends of the first conductive connection line 51 are respectively connected to the first detection point 431 and the processor 10, and the second conductive connection line 52 is respectively connected to the second detection point 432 and the processor 10. The conductive connection line 51 and the second conductive connection line 52 are connected to different pins of the processor 10 to form a conductive loop. The second conductive connection line 52 is grounded. The processor 10 is used to obtain the voltage of the first circuit board 20 to the ground and determine the hardware status of the display screen assembly 100 according to the voltage of the first circuit board 20 to the ground.

[0061] Thus, the annular conductive wire 43 surrounds the non-display area 42 of the display panel 40. If the display panel 40 is damaged around the four sides, the annular conductive wire 43 will form a short circuit. The first conductive connection wire 51 and the second conductive connection wire 52 are on the surface of the first circuit board 20 and the first flexible connection member 30. When the first flexible connection member 30 is not plugged in, the first conductive connection wire 51 or the second conductive connection wire 52 at the corresponding position will form a short circuit. Therefore, the on and off of the annular conductive wire 43, the first conductive connection wire 51 and the second conductive connection wire 52 will affect the size of the resistance in the entire circuit, thereby affecting the voltage of the first circuit board 20 to the ground. Therefore, the processor 10 can determine the hardware status of the display screen assembly 100 according to the voltage of the first circuit board 20 to the ground. Therefore, it is possible to detect whether the display screen assembly 100 is damaged while detecting whether the first flexible connection member 30 is plugged in, simplifying the detection process.

[0062] Optionally, in one embodiment, the processor 10 may be but is not limited to a central processing unit (CPU), other general-purpose processors, digital signal processors (DSP), application-specific integrated circuits (ASIC), field-programmable gate arrays (FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc.

[0063] It is understandable that the display screen assembly 100 also includes a memory, which may include a high-speed random access memory, and may also include a non-volatile memory, such as a hard disk, a memory, a plug-in hard disk, a smart memory card (SmartMedia Card, SMC), a secure digital (Secure Digital, SD) card, a flash card (Flash Card), multiple disk storage devices, flash memory devices, or other volatile solid-state storage devices. The memory stores a computer program for the processor 10 to execute to obtain the voltage of the first circuit board 20 to the ground and determine the hardware status of the display screen assembly 100 according to the voltage of the first circuit board 20 to the ground.

[0064] Optionally, in one embodiment, the memory stores a plurality of different preset voltage values ​​or ranges. The plurality of different preset voltage values ​​or ranges correspond to different hardware conditions of the display screen assembly 100. Therefore, when the processor 10 obtains the voltage of the first circuit board 20 to the ground, the obtained voltage value is compared with the preset voltage value or range, so that the hardware condition of the display screen assembly 100 corresponding to the voltage of the first circuit board 20 to the ground can be determined.

[0065] Optionally, in one embodiment, the first circuit board 20 is a PCB (Printed Circuit Board) circuit board or a PCBA (Printed Circuit Board Assembly) circuit board. The first flexible connector 30 is an FPC (Flexible Printed Circuit board). The first flexible connector 30 is plugged into the display panel 40.

[0066] Alternatively, in one embodiment, please refer to Figure 2 , Figure 2 1 is a schematic diagram of a module of a display screen assembly in a second embodiment of the present application. The display screen assembly 100 further includes a second circuit board 60 and a second flexible connector 70. One end of the first flexible connector 30 is connected to the first circuit board 20, and the other end is pluggably connected to one end of the second circuit board 60. The other end of the second circuit board 60 is connected to the display panel 40 via the second flexible connector 70. The first conductive connection line 51 and the second conductive connection line 52 are sequentially arranged on the surface of the second circuit board 60 and the second flexible connector 70 to form a conductive loop.

[0067] Thus, the first flexible connector 30 is pluggable and disposed on the second circuit board 60. Whether the first flexible connector 30 is accurately plugged into the second circuit board 60 can be determined by whether the first conductive connection line 51 and the second conductive connection line 52 are disconnected. Specifically, when the first conductive connection line 51 and / or the second conductive connection line 52 are disconnected, it is determined that the first flexible connector 30 is not properly plugged into the second circuit board 60.

[0068] Optionally, in one embodiment, the second circuit board 60 is a PCB circuit board or a PCBA circuit board. The second flexible connector 70 is one of COF (Chip On Film), COG (Chip On Glass) and FPC.

[0069] Alternatively, in one embodiment, please refer to Figure 3 , Figure 3 Schematic diagram of the module of the display screen assembly in the third embodiment of the present application. The first flexible connector 30, the second circuit board 60 and the second flexible connector 70 are respectively two. The two second circuit boards 60 are arranged side by side on the side of the display panel 40 close to the first circuit board 20, and are located between the display panel 40 and the first circuit board 20. The two second flexible connectors 70 are arranged side by side on the side of the display panel 40 close to the first circuit board 20, and are located between the display panel 40 and the two second circuit boards 60. Each second flexible connector 70 is arranged corresponding to one second circuit board 60 and connected between the display panel 40 and the corresponding second circuit board 60. The two first flexible connectors 30 are arranged side by side between the two second circuit boards 60 and the first circuit board 20, and each first flexible connector 30 is correspondingly connected to the second circuit board 60 in a pluggable manner. The first conductive connection line 51 is arranged on one of the first flexible connectors 30, the corresponding second circuit board 60 and the corresponding second flexible connector 70. The second conductive connection line 52 is disposed on another one of the first flexible connectors 30 , the corresponding second circuit board 60 , and the corresponding second flexible connector 70 .

[0070] Therefore, whether the two first flexible connectors 30 are plugged in place is detected by the first conductive connection line 51 and the second conductive connection line 52 respectively, which simplifies the detection process.

[0071] Optionally, in one embodiment, the annular conductive wire 43, the first conductive connecting wire 51 and the second conductive connecting wire 52 are all metal conductive wires. In this embodiment, the annular conductive wire 43, the first conductive connecting wire 51 and the second conductive connecting wire 52 can be but not limited to being made of conductive metal, such as copper, aluminum, etc. Although these conductive metals have good conductivity, their resistance is relatively large when their radius is very small. Therefore, in actual use, the annular conductive wire 43, the first conductive connecting wire 51 and the second conductive connecting wire 52 can all act as conductive resistors. That is, the first detection point 431 and the second detection point 432 divide the annular conductive wire 43 into a first line segment 433 and a second line segment 434. The first line segment 433 has a first resistor R1. The second line segment 434 has a second resistor R2. Since the lengths of the first line segment 433 and the second line segment 434 are different. Therefore, the first resistor R1 is different from the second resistor R2. In this embodiment, the first line segment 433 is a long path and the second line segment 434 is a short path. Therefore, the resistance of the first resistor R1 is greater than the resistance of the second resistor R2. Furthermore, since the routing of the first conductive connecting line 51 and the second conductive connecting line 52 is relatively short, the resistance of the first conductive connecting line 51 and the second conductive connecting line 52 can be ignored. The resistance of the first circuit board 20 to the ground is the third resistor R3. It can be understood that in the present application, the first resistor R1, the second resistor R2 and the third resistor R3 are equivalent resistors, which can be the resistance value of an equivalent resistor or the total resistance value of multiple equivalent resistors connected in series and / or in parallel. Therefore, the circuit diagram of the display screen assembly 100 can be equivalent to the following: Figure 4 The circuit diagram shown. Figure 4 In the figure, VDD is the voltage provided by the processor 10, and the voltage of the first circuit board 20 to the ground is the voltage across the third resistor R3, that is, VFB.

[0072] When the display panel 40 of the display screen assembly 100 is damaged around or the first flexible connector 30 is not connected in place, the annular conductive wire 43, the first conductive connecting wire 51 and the second conductive connecting wire 52 at the corresponding position will be disconnected. In different situations, the on and off of the annular conductive wire 43, the first conductive connecting wire 51 and the second conductive connecting wire 52 will affect the size of the resistance in the entire circuit. The voltage VFB applied across the third resistor R3 will change accordingly. Therefore, the hardware condition of the display screen assembly 100 can be judged according to the voltage change of the voltage VFB applied across the third resistor R3.

[0073] Optionally, in one embodiment, under different hardware states, the voltage across the third resistor R3 is determined by at least one resistance value of the first resistor R1, the second resistor R2 and the third resistor R3, and the different voltages across the third resistor R3 are used to represent different hardware states of the display screen assembly 100, and the hardware state includes one of normal and abnormal.

[0074] Specifically, in one embodiment, please refer to Figure 4 , when the display panel 40 of the display screen assembly 100 is not damaged or the first flexible connector 30 is not properly connected, the annular conductive wire 43, the first conductive connecting wire 51 and the second conductive connecting wire 52 are all normally connected, and the first resistor R1 is connected in parallel with the second resistor R2 and then connected in series with the third resistor R3. At this time, the voltage VFB applied to both ends of the third resistor R3 is jointly determined by the first resistor R1, the second resistor R2 and the third resistor R3. That is, the voltage VFB applied to both ends of the third resistor R3 = VDD*R3 / {[R1*R2 / (R1+R2)]+R3}.

[0075] Optionally, in one embodiment, when the display panel 40 is damaged around the first line segment 433 of the annular conductive line 43, the first line segment 433 is also disconnected. At this time, the resistance of the first line segment 433 is equivalent to infinity, and the voltage across the third resistor R3 is determined by the second resistor R2 and the third resistor R3. At this time, the circuit diagram of the display screen assembly 100 can be equivalent to: Figure 5 As shown in the circuit diagram, the voltage VFB applied across the third resistor R3 is VDD*R3 / (R2+R3). That is, when the voltage across the third resistor R3 is independent of the first resistor R1 and is determined by the resistance values ​​of the second resistor R2 and the third resistor R3, it is determined that the hardware state is abnormal and the abnormal state is that the first line segment 433 is disconnected.

[0076] Optionally, in one embodiment, when the display panel 40 is damaged around the second line segment 434 of the annular conductive line 43, the second line segment 434 is also disconnected. At this time, the resistance of the second line segment 434 is equivalent to infinity, and the voltage across the third resistor R3 is determined by the first resistor R1 and the third resistor R3. At this time, the circuit diagram of the display screen assembly 100 can be equivalent to: Figure 6As shown in the circuit diagram, the voltage VFB applied across the third resistor R3 is VDD*R3 / (R1+R3). That is, when the voltage across the third resistor R3 is independent of the second resistor R2 and is determined by the resistance values ​​of the first resistor R1 and the third resistor R3, it is determined that the hardware state is abnormal and the abnormal state is that the second line segment 434 is disconnected.

[0077] Optionally, in one embodiment, when the first flexible connector 30 is not properly plugged in, the first conductive connection line 51 and / or the second conductive connection line 52 are disconnected. At this time, a complete conductive path is not formed, and the voltage across the third resistor R3 is zero. In other words, when the voltage across the third resistor R3 is zero, it is determined that the hardware state is abnormal and the abnormal state is that the first conductive connection line 51 and / or the second conductive connection line 52 are not properly plugged in.
