[0047] Various embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. In each of the drawings, identical elements are represented by identical or similar reference numerals. For clarity, the various parts in the drawings are not drawn to scale.

[0048] The following terms are used in this article:

[0049] An organic light-emitting diode (OLED) is a current-type light-emitting device consisting of an organic light-emitting material and a pair of electrodes. It has the characteristics of self-luminescence, fast response, wide viewing angle, and the ability to be manufactured on flexible substrates. Therefore, it is increasingly used in the field of high-performance display technology.

[0050] A display system is a device used to display images or video content for users to watch. It typically consists of a display panel and related circuits. Common display systems include liquid crystal display systems and organic light-emitting diode (OLED) display systems.

[0051] Electrostatic discharge (ESD) refers to the transfer of charge between two objects. ESD occurs when there is a difference in charge between the two objects. This difference can be caused by friction, contact, or an electric field. In display systems, ESD can damage chips and electronic components, causing device failure or malfunction. To prevent ESD from affecting display systems, appropriate measures must be taken to prevent and reduce its impact on the equipment.

[0052] FIG1 is a schematic diagram of the structure of a display system provided according to an embodiment of the present disclosure. As shown in FIG1 , the display system provided in this embodiment of the present disclosure includes: a display panel 110, a drive circuit 200, a display panel control device 150, and a power chip 160. The drive circuit 200 includes a source drive circuit 120, a gate drive circuit 130, and a timing control circuit 140. Exemplarily, the display panel 110 of the display system may be a liquid crystal display panel (i.e., an LCD display panel), a light-emitting diode display panel (i.e., an LED display panel), an organic light-emitting diode display panel (i.e., an OLED display panel), an active-matrix organic light-emitting diode display panel (i.e., an AMOLED display panel), an organic electroluminescent display panel (i.e., an OLED display panel), a plasma display panel (i.e., a PDP display panel), or a phosphorescent display panel (i.e., a CRT display panel).

[0053] In some embodiments, the display panel 110 includes a plurality of pixel units 111 arranged in an array. Each pixel unit 111 is connected to a source driver circuit 120 via a data line and to a gate driver circuit 130 via a scan line. In some embodiments, a timing control circuit 140 is configured to provide timing control signals, gamma voltages, and input data to the source driver circuit 120, and to input timing control signals to the gate driver circuit 130. The source driver circuit 120 generates a plurality of grayscale voltages Vsrc (i.e., data signals) based on the received timing control signals, gamma voltages, and input data, and transmits these grayscale voltages Vsrc (i.e., data signals) to each column of pixel units 111 via the data lines to drive the plurality of pixel units 111 in the display panel 110. The grayscale voltage (i.e., data signal) received by each pixel unit 111 corresponds to the grayscale voltage to be displayed by that pixel. The gate driver circuit 130 generates a scan signal Scan based on the received timing control signals and provides the scan signal Scan to each row of pixel units 111 via the scan lines. In some embodiments, the power chip 160 is connected to each pixel unit 111 in the display panel 110 to provide a power supply voltage ELVDD to each pixel unit 111. In some embodiments, the power chip 160 is also connected to the source driver circuit 120, the gate driver circuit 130, and the timing control circuit 140 to provide the source driver circuit 120, the gate driver circuit 130, and the timing control circuit 140 with a power supply voltage VDD.

[0054] Figure 2 shows a circuit diagram of pixel unit 111. Referring to Figure 2, pixel unit 111 includes an OLED, a switch transistor T1, a driver transistor T2, and a storage capacitor Cs. The on / off state of switch transistor T1 is controlled by a scan signal Scan. Storage capacitor Cs receives a grayscale voltage Vsrc (i.e., the data signal) via switch transistor T1 and stores electrical energy to maintain the gate-source voltage Vgs of driver transistor T2 at (ELVDD-Vsrc). The first terminal of the OLED is connected to the source terminal of driver transistor T2, which is also connected to a common voltage Vcom. Driver transistor T2 is configured to provide a drive current to the OLED based on the gate-source voltage Vgs during the off phase of switch transistor T1. The greater the gate-source voltage Vgs, the greater the drive current received by the OLED, and the greater the brightness of the OLED. Furthermore, different settings for the grayscale voltage Vsrc (i.e., the data signal) result in different gate-source voltages Vgs. Therefore, by adjusting the grayscale voltage Vsrc (i.e., the data signal), the OLED can achieve multi-grayscale display. In some embodiments, the power chip 160 provides a common voltage Vcom to each pixel unit 111 in the display panel 110. In some embodiments, the common voltage Vcom can be set to a ground (GND) voltage. It is easy to understand that the ground (GND) voltage refers to the reference point or zero potential point in the circuit.

[0055] In some embodiments, the display panel control device 150 is used to control the driving circuit 200 to adjust the scan signal Scan and / or grayscale voltage Vsrc (i.e., data signal) provided to the display panel 110 when electrostatic discharge occurring in the display system interferes with the driving circuit 200, thereby controlling the display screen of the display panel 110.

[0056] It should be noted that the display panel control device 150 may also be provided in the display panel 110. When electrostatic discharge occurring in the display system interferes with the drive circuit 200, the display panel control device 150 may control the drive circuit 200 to adjust the scan signal Scan and / or the grayscale voltage Vsrc (i.e., the data signal) provided to the pixel unit 111 of the display panel 110, thereby controlling the display image of the display panel 110.

[0057] Since the specific process of controlling the display screen of the display panel 110 will be described in detail below, it will not be repeated here.

[0058] In some embodiments, as shown in FIG. 1 , the display panel control device 150 includes a voltage detection unit 151 and a control unit 152 .

[0059] In some embodiments, the voltage detection unit 151 detects fluctuations in the voltage of the display system's power supply signal and, based on the detection results, determines whether electrostatic discharge (ESD) occurring in the display system interferes with the driver circuit 200 in the display system. It should be noted that the power supply signal includes a power supply voltage signal and a ground voltage signal. The power supply voltage signal refers to the power supply voltage signal output by the power chip 160 in the display system, which supplies the various sub-circuits in the display system. This power supply voltage signal is a DC voltage signal with a constant voltage value. Examples include the power supply voltage VDD, power supply voltage ELVDD, and common voltage Vcom mentioned above. The ground voltage signal refers to the ground (GND) voltage signal, which is the reference point or zero potential point in the driver circuit 200 and display panel 110 in the display system. It should be noted that in a display system, during electrostatic discharge, electrostatic charge is transferred in a relatively short period of time, generating an electrostatic current. High electrostatic current can distort signals transmitted around it (e.g., the power supply signal). Under normal operation, the display system's power supply signal is a DC voltage signal with a constant voltage value. Therefore, by detecting the fluctuation of the power supply signal in the display system, it is possible to determine whether electrostatic discharge occurs in the display system and whether the electrostatic discharge occurs in the display system and causes interference to the driving circuit 200 in the display system.

[0060] In some embodiments, the voltage detection unit 151 detects whether the fluctuation in the voltage value of the power supply signal meets a preset condition. If so, it is determined that electrostatic discharge in the display system is interfering with the driver circuit 200. In some embodiments, the preset condition is that the voltage difference between the maximum and minimum voltage values ​​of the power supply signal reaches a preset voltage difference within a preset time range. The voltage detection unit 151 detects whether the voltage difference between the maximum and minimum voltage values ​​of the power supply signal reaches a preset voltage difference within a preset time range. If so, it is determined that electrostatic discharge in the display system is interfering with the driver circuit 200. Figure 3A is a schematic diagram of a power supply signal according to one embodiment of the present disclosure. Figure 3B is an enlarged view of the power supply signal within the boxed area shown in Figure 3A. As shown in Figures 3A and 3B, the power supply signal is a DC voltage signal. Under normal operating conditions, the voltage value of the power supply signal is v0 (e.g., v0 = 8V). During the time range from t1 to t2, the voltage value of the power supply signal fluctuates dramatically. At time t3, the voltage value of the power supply signal is the maximum voltage value v3 (for example, v3 = 14V), and at time t4, the voltage value of the power supply signal is the minimum voltage value v4 (for example, v4 = 4V). In the time range from t3 to t4, the voltage difference of the power supply signal is v3-v4 (for example, 14V-4V = 10V). If the preset time range is the time range from t1 to t2, and the preset voltage difference is 8V, then in this case, the voltage detection unit 151 determines that the electrostatic discharge phenomenon occurring in the display system has caused interference to the driving circuit 200.

[0061] In some embodiments, the preset condition is that the voltage value of the power supply signal is higher than the first preset voltage threshold v1 for a preset time duration, and / or the voltage value of the power supply signal is lower than the second preset voltage threshold v2 for a preset time duration. In some embodiments, the voltage detection unit 151 detects whether the voltage value of the power supply signal is higher than the first preset voltage threshold v1 for a preset time duration. If the voltage value of the power supply signal is higher than the first preset voltage threshold v1 for a preset time duration, it is determined that the electrostatic discharge phenomenon in the display system has caused interference with the driving circuit 200. In some embodiments, the voltage detection unit 151 detects whether the voltage value of the power supply signal is lower than the second preset voltage threshold v2 for a preset time duration. If the voltage value of the power supply signal is lower than the second preset voltage threshold v2 for a preset time duration, it is determined that the electrostatic discharge phenomenon in the display system has caused interference with the driving circuit 200. In some embodiments, the voltage detection unit 151 detects whether the duration of the voltage value of the power supply signal exceeding the first preset voltage threshold v1 reaches a preset time length, and detects whether the duration of the voltage value of the power supply signal exceeding the second preset voltage threshold v2 reaches a preset time length. If both durations reach the preset time length, it is determined that the electrostatic discharge phenomenon occurring in the display system has caused interference with the driving circuit 200. In some embodiments, the voltage detection unit 151 detects whether the sum of the duration of the voltage value of the power supply signal exceeding the first preset voltage threshold v1 and the duration of the voltage value of the power supply signal exceeding the second preset voltage threshold v2 reaches a preset time length. If the sum of the durations reaches the preset time length, it is determined that the electrostatic discharge phenomenon occurring in the display system has caused interference with the driving circuit 200. In one example, as shown in Figures 3A and 3B, the voltage value of the power supply signal is higher than the first preset voltage threshold v1 during the time ranges t5 to t6 and t9 to t10, and is lower than the second preset voltage threshold v2 during the time ranges t7 to t8 and t11 to t12. If the sum of the durations from t5 to t6 and from t9 to t10 is greater than the preset time length, and the sum of the durations from t7 to t8 and from t11 to t12 is greater than the preset time length, then in this case, the voltage detection unit 151 determines that the electrostatic discharge phenomenon occurring in the display system causes interference to the driving circuit 200.

[0062] In some embodiments, the preset condition is that the voltage value of the power supply signal exceeds the first preset voltage threshold v1 a preset number of times within a preset time range, and / or the voltage value of the power supply signal falls below the second preset voltage threshold v2 a preset number of times within a preset time range. In some embodiments, the voltage detection unit 151 detects whether the voltage value of the power supply signal exceeds the first preset voltage threshold v1 a preset number of times within a preset time range. If the voltage value of the power supply signal exceeds the first preset voltage threshold v1 a preset number of times, it is determined that the electrostatic discharge phenomenon in the display system has caused interference with the driving circuit 200. In some embodiments, the voltage detection unit 151 detects whether the voltage value of the power supply signal falls below the second preset voltage threshold v2 a preset number of times within a preset time range. If the voltage value of the power supply signal falls below the second preset voltage threshold v2 a preset number of times within the preset time range, it is determined that the electrostatic discharge phenomenon in the display system has caused interference with the driving circuit 200. In some embodiments, the voltage detection unit 151 detects whether the number of times the voltage value of the power supply signal exceeds the first preset voltage threshold v1 within a preset time range reaches a preset number, and detects whether the number of times the voltage value of the power supply signal falls below the second preset voltage threshold v2 within a preset time range reaches a preset number. If both of these numbers reach the preset number, it is determined that the electrostatic discharge phenomenon occurring in the display system has caused interference with the driving circuit 200. In some embodiments, the voltage detection unit 151 detects whether the total number of times the voltage value of the power supply signal exceeds the first preset voltage threshold v1 and the total number of times the voltage value of the power supply signal falls below the second preset voltage threshold v2 within a preset time range reaches a preset number. If the total number reaches the preset number, it is determined that the electrostatic discharge phenomenon occurring in the display system has caused interference with the driving circuit 200. In one example, as shown in Figures 3A and 3B, within the time range from t1 to t2, the voltage value of the power supply signal exceeds the first preset voltage threshold v1 four times, and the voltage value of the power supply signal falls below the second preset voltage threshold v2 four times. If the preset number of times associated with the first preset voltage threshold v1 is 2 and the preset number of times associated with the second preset voltage threshold v2 is 2, then in this case, the voltage detection unit 151 determines that the electrostatic discharge phenomenon occurring in the display system interferes with the driving circuit 200 .

[0063] In some embodiments, if the control unit 152 determines that electrostatic discharge (ESD) in the display system interferes with the driver circuit 200, it provides a control signal Scontrol to the driver circuit 200. Based on the control signal Scontrol, the driver circuit 200 adjusts the scan signal Scan and / or grayscale voltage Vsrc (i.e., data signal) provided to the display panel 110 in the display system, thereby controlling the display image of the display panel 110. In some embodiments, if the control unit 152 determines that electrostatic discharge (ESD) in the display system interferes with the driver circuit 200, it provides a control signal Scontrol to the timing control circuit 140. Based on the control signal Scontrol, the timing control circuit 140 adjusts the timing control signals provided to the source driver circuit 120 and the gate driver circuit 130, thereby adjusting the grayscale voltage Vsrc (i.e., data signal) generated by the source driver circuit 120 and / or the scan signal Scan generated by the gate driver circuit 130, thereby controlling the display image of the display panel 110. In this way, by adjusting the grayscale voltage Vsrc (i.e., the data signal) and / or the scan signal Scan, it is possible to prevent the grayscale voltage Vsrc (i.e., the data signal) and the scan signal Scan from being provided to the display panel 110 and being interfered with by electrostatic discharge. This protects the display image of the display panel from interference from electrostatic discharge, ensures normal display of the display image of the display panel, and improves the display quality of the display panel. In some embodiments, if the control unit 152 determines that electrostatic discharge in the display system is interfering with the drive circuit 200, it provides a control signal Scontrol to the timing control circuit 140. The timing control circuit 140 adjusts the timing control signals provided to the source driving circuit 120 and the gate driving circuit 130 according to the control signal Scontrol, thereby causing the source driving circuit 120 to stop generating the grayscale voltage Vsrc (i.e., the data signal), and causing the gate driving circuit 130 to stop generating the scan signal Scan. In this way, by suspending the provision of the grayscale voltage Vsrc (i.e., the data signal) and the scan signal Scan to the display panel 110, it is possible to avoid providing the display panel 110 with the grayscale voltage Vsrc (i.e., the data signal) and the scan signal Scan that are interfered with by electrostatic discharge. The display screen of the display panel can be protected from interference from the electrostatic discharge phenomenon, thereby ensuring the normal display of the display screen of the display panel and improving the display quality of the display panel.
