Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0034] Referring to "embodiment" herein means that a specific feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0035] The present application will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0036] Please refer to Figure 1 , Figure 1 , which is a schematic structural diagram of a detection device provided by an embodiment of the present application. In this embodiment, a detection device is provided, which can be used to detect the response time of the refresh frequency switching of a display panel, so that users can evaluate the quality of the display panel based on the detected response time, thereby improving the ex-factory yield of the display panel. Among them, the display panel can be a display panel used for display on intelligent terminal devices such as mobile phones, tablets, and in-vehicle displays.

[0037] As Figure 1As shown in the figure, the detection device includes a carrier 1, a power circuit 2, a touch element 3, and a monitor 5. Among them, the touch element 3 can be arranged on the carrier 1 to reduce the floor area. The monitor 5 can be an oscilloscope.

[0038] Among them, the carrier 1 is used to carry the display panel. In a specific embodiment, as Figure 1 shown, the surface of the carrier 1 can be provided with a limiting groove for accommodating the display panel to limit the display panel carried thereon and prevent the display panel from moving. Among them, the size of the limiting groove is adjustable to adapt to display panels of different sizes.

[0039] The touch element 3 is used to apply a touch signal to the display panel so that the refresh frequency of the display panel is switched from a first frequency to a second frequency. Among them, the touch signal can be a contact touch signal or a hover touch signal. When the touch signal is a contact touch signal, the touch element 3 specifically contacts the surface of the display panel to touch the display panel. Among them, the touch element 3 can be a conductor, and the touch layer of the display panel can be capacitive or resistive. It can be understood that if the touch layer of the display panel is resistive, the touch element 3 can be an insulator. In this specific embodiment, the touch element 3 can be a nano-conductive head or an existing stylus, and the present application does not limit this, as long as it can touch the display panel to refresh the display frequency of the display panel. When the touch signal is a hover touch signal, the touch element 3 does not contact the surface of the display panel. When the touch element 3 is located at the corresponding position of the display panel, the display panel senses the touch element 3 so that the display refresh frequency is switched from the first frequency to the second frequency. For the specific touch element 3 corresponding to this embodiment, reference can be made to existing devices that can apply hover touch induction signals, which will not be elaborated here.

[0040] The power circuit 2 can be configured to be in a conducting state or a disconnected state. Among them, when the touch element 3 applies a touch signal to the display panel, the power circuit 2 is configured to be in a conducting state; when the touch element 3 does not apply a touch signal to the display panel, the power circuit 2 is configured to be in a disconnected state.

[0041] Please refer to Figure 2 , Figure 2 which is a schematic structural diagram of the detection device provided by another embodiment of the present application; the power circuit 2 includes a power supply 21 and a conductive mechanism 4; the power supply 21 and the conductive mechanism 4 can be arranged on the carrier 1. Among them, the power supply 21 includes a first electrode 211 and a second electrode 212 with opposite polarities. Among them, the first electrode 211 can be the positive electrode; the second electrode 212 is the negative electrode. Of course, the first electrode 211 can also be the negative electrode, and the second electrode 212 is the positive electrode. In a specific embodiment, the voltage provided by the power supply 21 is adjustable, and it can specifically be an adjustable constant voltage power supply.

[0042] The conductive mechanism 4 is electrically connected to the first electrode 211 and the second electrode 212 of the power supply 21 respectively to form a circuit. Among them, when the touch element 3 applies a touch signal to the display panel, the conductive mechanism 4 makes the circuit conduct, so that the power supply circuit 2 is configured to be in a conductive state. When the touch element 3 does not apply a touch signal to the display panel, the circuit is disconnected, so that the power supply circuit 2 is configured to be in a disconnected state.

[0043] The monitor 5 includes a first channel 51 and a second channel 52. The first channel 51 of the monitor 5 is electrically connected to the circuit, and is used to monitor the conduction signal of the power supply circuit 2 and obtain the first moment corresponding to when the conduction signal is monitored. Specifically, the first channel 51 of the monitor 5 is electrically connected to the conductive mechanism 4 to monitor the voltage signal when the circuit conducts, and obtain the moment when the voltage signal is monitored as the first moment.

[0044] The second channel 52 is used to be electrically connected to the display panel, monitor the frequency signal corresponding to the refresh frequency of the display panel, and obtain the second moment corresponding to when the second frequency signal is monitored. In a specific embodiment, after the second channel 52 is electrically connected to the display panel, the monitor 5 is specifically used to receive the tearing (Tearing Effect Signal, TE) signal of the display panel. When the display panel does not receive a touch signal, the TE signal received by the monitor 5 is the first TE signal; among them, when the TE signal received by the monitor 5 is the first TE signal, the corresponding refresh frequency of the display panel is the first frequency. After the display panel receives a touch signal, the TE signal received by the monitor 5 changes from the first TE signal to a different second TE signal; at this time, the refresh frequency of the display panel changes from the first frequency to the second frequency. Among them, the monitor 5 obtains the corresponding current moment at the same time after receiving the second TE signal as the second moment.

[0045] In a specific embodiment, the monitor 5 obtains the response time of the refresh frequency switching of the display panel based on the first moment and the second moment. Specifically, the monitor 5 determines the response time of the refresh frequency switching of the display panel based on the difference between the first moment and the second moment. For example, if the first moment detected by the monitor 5 is T1 and the second moment is T2, then the response time T0 of the refresh frequency switching of the display panel = T2 - T1.

[0046] In one embodiment, refer to Figure 3 , Figure 3 is a schematic structural diagram of the detection device provided by another embodiment of the present application. The conductive mechanism 4 specifically includes a first conductive member 41 and a second conductive member 42.

[0047] Among them, the first end of the first conductive member 41 is electrically connected to the first electrode 211, and the second end of the first conductive member 41 is used to be electrically connected to the second conductive member 42. In a specific embodiment, the first end of the first conductive member 41 can be electrically connected to the first electrode 211 through a conductive connection line. The second end of the first conductive member 41 is used to partially contact the second conductive member 42 to achieve electrical connection between the two.

[0048] The second conductive member 42 is electrically connected to the second electrode 212; and the second conductive member 42 can be configured into different first states and second states. When the second conductive member 42 is configured into the first state, the second conductive member 42 is electrically connected to the second end of the first conductive member 41 to make the loop conductive. When the second conductive member 42 is configured into the second state, the second conductive member 42 is spaced apart from the first conductive member 41 to make the loop disconnected.

[0049] Specifically, the second conductive member 42 can be a conductive rod. When the conductive rod is configured into the first state, the first end of the conductive rod contacts the second end of the first conductive member 41 to conduct the loop. When the conductive rod is configured into the second state, the first end of the conductive rod is spaced apart from the second end of the first conductive member 41 to disconnect the loop. In a specific embodiment, the second conductive member 42 is entirely made of a conductive material, such as copper, aluminum, or a copper-aluminum alloy, etc. Of course, in other embodiments, the second conductive member 42 can also include an insulator and a conductive layer formed on the surface of the insulator. Among them, the insulator can be ceramic or glass, etc., and the conductive layer can be a copper layer. Among them, the conductive layer can be provided only corresponding to the position of the second conductive member 42 for connecting the loop to save costs and prevent electric shock.

[0050] In this embodiment, the touch element 3 is specifically arranged at the second end of the conductive rod; so that when the touch element 3 contacts the display panel, the conductive rod is simultaneously made to conduct the loop.

[0051] In one embodiment, please continue to refer to Figure 3 , the conductive mechanism 4 further includes an insulating carrier 43.

[0052] The insulating bearing member 43 includes a first bearing portion 431 and a second bearing portion 432 which are arranged vertically. The first bearing portion 431 is arranged on the bearing platform 1 perpendicular to the plane where the bearing platform 1 is located. One end of the second bearing portion 432 is connected to the end of the first bearing portion 431 which is away from the bearing platform 1. The first bearing portion 431 and / or the second bearing portion 432 are in the shape of an elongated strip, and the material of the first bearing portion 431 and / or the second bearing portion 432 can be an insulating material, such as glass, ceramic, etc.; the present application takes the case where the material of the first bearing portion 431 and the second bearing portion 432 are both insulating materials as an example. Of course, in other embodiments, the first bearing portion 431 and / or the second bearing portion 432 can also include a conductor and an insulating layer arranged on its surface. Among them, the material of the conductor can be iron, steel or iron-aluminum alloy, etc., and the material of the insulating layer can be phenolic resin, chloroprene rubber, polyvinyl acetal, etc.

[0053] In a specific embodiment, the first end of the first conductive member 41 is disposed on a side of the second bearing portion 432 away from the first bearing portion 431. The second end of the first conductive member 41 passes through the second bearing portion 432 and is disposed on a side of the second bearing portion 432 close to the first bearing portion 431, so as to contact the second conductive member 42, thereby achieving electrical connection between the first conductive member 41 and the second conductive member 42.

[0054] The second conductive member 42 is movably connected to the first bearing portion 431 to be configured in a first state or a second state. Figure 3 As shown, the second conductive member 42 is rotatably connected to the first bearing portion 431, for example, the middle portion of the second conductive member 42 is rotatably connected to the first bearing portion 431 via a rotating shaft, so as to configure the second conductive member 42 to the first state or the second state. In another specific embodiment, the second conductive member 42 can also be slidably connected to the first bearing portion 431, so as to configure the second conductive member 42 to the first state or the second state. The present application does not impose any restrictions on this, as long as it is ensured that when the conductive rod is configured to the first state, the first end of the conductive rod is in contact with the first conductive member 41, and the touch element 3 can be in contact with the display panel. When the conductive rod is configured to the second state, the first end of the conductive rod is spaced from the first conductive member 41.

[0055] In one embodiment, see Figure 4 , Figure 4 This is a schematic structural diagram of a detection device provided in yet another embodiment of the present application; the conductive mechanism 4 also includes a third conductive member 44 .

[0056] The third conductive member 44 is disposed on the insulating carrier 43, and the third conductive member 44 is electrically connected to the second electrode 212 through a conductive connection line. Specifically, the second conductive member 42 is electrically connected to the second electrode 212 through the third conductive member 44. In this way, during the rotation of the second conductive member 42, the electrical connection between the third conductive member 44 and the second electrode 212 can be effectively avoided from being affected, thereby ensuring the effective electrical connection between the third conductive member 44 and the second electrode 212.

[0057] In a specific embodiment, the third conductive member 44 may be disposed corresponding to the position A where the second conductive member 42 is rotatably connected to the first carrier portion 431. In this way, during the rotation of the second conductive member 42, the relative position between the third conductive member 44 and the second conductive member 42 can be ensured to be fixed, so as to avoid affecting the electrical connection between the second conductive member 42 and the third conductive member 44. Of course, the third conductive member 44 may also be connected to other positions of the second conductive member 42 and may move synchronously with the rotation of the second conductive member 42 to ensure the relative position of the two is fixed.

[0058] Specifically, the third conductive member 44 may serve as the rotation axis for the second conductive member 42 to rotate relative to the first carrier portion 431. In this way, while realizing the rotational connection between the second conductive member 42 and the first carrier portion 431, the electrical connection between the second conductive member 42 and the second electrode 212 can be realized, effectively reducing the cost and simplifying the process.

[0059] In a specific embodiment, as Figure 4 shown, the first channel 51 of the monitor 5 is specifically electrically connected to the third conductive member 44 of the conductive mechanism 4 to monitor the first moment corresponding to when the circuit is turned on. Compared with the scheme where the first channel 51 of the monitor 5 is electrically connected to other positions of the conductive mechanism 4, the electrical connection between the first channel 51 of the monitor 5 and the circuit will not be affected by the second conductive member 42, and the effective electrical connection between the first channel 51 and the circuit can be effectively ensured.

[0060] The detection device provided in this embodiment applies a touch signal to the display panel by setting the touch element 3, so that the refresh frequency of the display panel is switched from the first frequency to the second frequency. At the same time, by setting the power supply circuit 2, when the touch element 3 applies a touch signal to the display panel, the power supply circuit 2 is configured to be in a conducting state, the conducting signal of the power supply circuit 2 is monitored by the monitor 5, and the first moment when the conducting signal is monitored is obtained; in addition, the frequency signal corresponding to the refresh frequency of the display panel is monitored by the monitor 5, and the second moment corresponding to when the frequency signal of the second frequency is monitored is obtained, so that the monitor 5 detects the response time of the refresh frequency switching of the display panel based on the first moment and the second moment, quantifies the response time of the refresh frequency switching of the display panel, and further evaluates the performance of the display panel based on this response time.

[0061] Please refer to Figure 5 , Figure 5 which is a flowchart of the detection method provided by an embodiment of the present application. The detection method is specifically executed by using the detection device involved in any of the above embodiments. The specific structure and function of the detection device can be seen in the above relevant description, and will not be elaborated here.

[0062] Specifically, the detection method includes:

[0063] Step S1: Monitor the conduction signal of the power supply circuit and obtain the first moment when the conduction signal is monitored.

[0064] In the specific implementation process, place the display panel on the carrier 1, and then electrically connect the first channel 51 of the monitor 5 to the power supply circuit to monitor the conduction signal of the power supply circuit 2. Then, make the touch element 3 apply a touch signal to the display panel and configure the power supply circuit 2 to a conducting state. Use the first channel 51 of the monitor 5 to monitor the conduction signal of the power supply circuit 2 and obtain the corresponding first moment when the conduction signal is monitored. Among them, the first moment is the moment corresponding to the monitor 5 receiving the voltage signal of the power supply circuit 2.

[0065] Step S2: Monitor the frequency signal corresponding to the refresh frequency of the display panel and obtain the second moment when the frequency signal corresponding to the second frequency is monitored.

[0066] Specifically, use the monitor 5 to simultaneously monitor the TE signal of the display panel and obtain the corresponding second moment when the frequency signal corresponding to the second frequency is monitored. Among them, the execution order of step S2 and step S1 has no priority, and the monitor 5 monitors the first moment and the second moment in real time.

[0067] Step S3: Obtain the response time of the refresh frequency switching of the display panel based on the first moment and the second moment.

[0068] In the specific implementation process, the monitor 5 specifically obtains the response time of the refresh frequency switching of the display panel based on the difference between the first moment and the second moment. Specifically, if the first moment detected by the monitor 5 is T1 and the second moment is T2, then the response time T0 of the refresh frequency switching of the display panel = T2 - T1.

[0069] The detection method provided in this embodiment utilizes the detection device involved above. By monitoring the conduction signal of the power supply circuit 2 and obtaining the first moment corresponding to when the conduction signal is monitored; and monitoring the TE signal of the display panel to obtain the second moment corresponding to when the frequency signal corresponding to the second frequency is monitored; then, based on the first moment and the second moment, the response time of the refresh frequency switching of the display panel is obtained to quantify the response time of the refresh frequency switching of the display panel. Furthermore, based on this response time, the performance of the display panel can be evaluated, and the yield rate of the product at the time of factory shipment can be improved.

[0070] The above are only the implementation manners of the present application, and do not limit the patent scope of the present application accordingly.
