Description

Technical Field

[0001] The present application relates to the field of display technologies, and particularly to a display panel, a driving method, a device and a computer-readable storage medium thereof. Background Art

[0002] Currently, display panels such as TVs (Televisions), MNTs (Monitors), and NBs (Notebooks) often have problems with abnormal startup in low-temperature environments. This is because the internal electron mobility of TFTs (Thin-Film Transistors) decreases in low-temperature environments, the Ion is insufficient, and the gate high voltage VGH applied to the TFTs decreases, resulting in the display panel being unable to be normally turned on.

[0003] To overcome this problem, the solution adopted in related technologies is to add low-temperature compensation to VGH. The specific approach is to add a thermistor in the VGH circuit, and change the resistance value according to the change in the ambient temperature, thereby changing the VGH voltage. However, due to the installation position of the thermistor and its own performance, using the thermistor to detect the ambient temperature will cause the detected temperature during actual operation to be higher than the ambient temperature, resulting in inaccurate low-temperature compensation. Summary of the Invention

[0035] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present application. However, those skilled in the art should clearly understand that the embodiments of the present application can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to avoid unnecessary details from interfering with the description of the embodiments of the present application.

[0036] Currently, display panels such as TVs (Television), MNTs (Monitor), and NBs (Notebook) often have problems with abnormal startup in low-temperature environments. This is because the internal electron mobility of TFTs (Thin-Film Transistor) decreases in low-temperature environments, the Ion is insufficient, and the gate-on voltage VGH given to the TFT decreases (the signal given to the in-plane is a high CLK voltage and cannot reach the voltage level set by VGH due to attenuation, as Figure 1 shown), resulting in the display panel being unable to be normally turned on at low temperatures.

[0037] To overcome this problem, the solution adopted in the related art is to add low-temperature compensation to VGH. The specific method is to add a thermistor in the VGH circuit, and change the resistance value through the change of the ambient temperature, thereby changing the VGH voltage. As Figure 2 shown, at room temperature (T > T1), the VGH voltage is V1. When the temperature of the thermistor drops to T1, temperature compensation starts. The lower the temperature, the greater the VGH voltage, and it increases linearly. When the temperature drops to T2, the VGH voltage no longer increases. Combining Figure 1 it can be known that because the VGH voltage of the TFT decreases at low temperatures, providing a larger VGH at low temperatures to offset the voltage attenuation helps to turn on the in-plane TFT.

[0038] However, there will be the following situations when using a thermistor to detect the ambient temperature: ① The thermistor is on the PCB (Printed Circuit Board). When the PCB is working normally, it will heat up, causing the thermistor to heat up. In this way, the temperature of the thermistor will be higher than the ambient temperature; ② The thermistor itself will also heat up when it is working. This results in the detected temperature being higher than the ambient temperature during actual operation. Then, the timing of the temperature compensation startup is not accurate enough, or when shutting down and restarting, since the shutdown time is short, the temperature of the thermistor has not completely dissipated, making the resistance temperature still higher than the ambient temperature.

[0039] Based on this, the embodiments of the present application provide a display panel, a driving method, a device and a computer-readable storage medium thereof. By combining the in-plane feedback signal and the reference signal to determine the compensation value, the compensation timing can be made more accurate and the compensation effect can be better. There is no need to use a thermistor to detect the ambient temperature, overcoming the defect that the low-temperature compensation effect is not accurate enough in the related art by using a thermistor to detect the temperature, so that the display panel can be normally started in a low-temperature environment.

[0040] The display panel, the driving method, the device and the computer-readable storage medium thereof provided by the embodiments of the present application will be specifically described through the following embodiments. First, the driving method of the display panel in the embodiments of the present application will be described.

[0041] The embodiments of the present application provide a driving method for a display panel. Refer to Figure 3 , Figure 3 which is a schematic flowchart of a driving method for a display panel provided by the embodiments of the present application. The driving method of the display panel can be applied to a display panel. As Figure 3 shown, the driving method of the display panel provided in this embodiment includes steps S10 to S30.

[0042] Step S10, obtain the in-plane feedback signal;

[0043] In this embodiment, the in-plane feedback signal can be fed back to the LS IC (Liquid Crystal Display Driver Integrated Circuit) through the in-plane trace. The LS IC is an integrated circuit designed for liquid crystal displays, which is responsible for converting the digital image signal into an analog voltage / current signal and driving the liquid crystal panel to achieve display. The in-plane feedback signal can be a CLK (clock signal) feedback signal based on the CLK signal transmitted by the LS IC to the in-plane, or the measured temperature obtained through the temperature sensor provided on the display panel.

[0044] Step S20, determine the compensation value according to the in-plane feedback signal and the reference signal;

[0045] In this embodiment, the LSIC will combine the in-plane feedback signal and the reference signal to know whether the display panel is in a low-temperature environment, so as to appropriately compensate the driving voltage provided by itself to the in-plane.

[0046] In some feasible embodiments, the above in-plane feedback signal includes a feedback clock signal, and the reference signal includes an initial clock signal sent by a level converter; the above step S20 may include:

[0047] Step S21, compare the feedback clock signal with the initial clock signal to obtain a comparison result, and determine the compensation value according to the comparison result.

[0048] In this embodiment, taking the in-plane feedback signal as a feedback clock signal as an example, the reference signal is the initial clock signal emitted by the level converter, and the signal to be compensated is also the CLK signal, thereby ultimately achieving the purpose of compensating the VGH voltage of the in-plane TFT.

[0049] It can be understood that after the LS IC receives the CLK signal fed back from the surface, it compares it with the initial CLK signal sent by the LS IC, and all CLK signals need to be fed back to the LS IC. All CLK signals need to be compensated to ensure that all TFTs that need to be turned on in the entire display panel can be turned on normally.

[0050] In some feasible embodiments, the above step S21 may specifically include:

[0051] Step S210: subtract the feedback clock signal from the initial clock signal to obtain a signal difference, and determine the signal difference as a compensation value.

[0052] In the present embodiment, when the ambient temperature of the display panel is low, the CLK signal fed back within the plane will be attenuated relative to the CLK signal output by the LS IC, resulting in the failure to reach the voltage level set by the VHG, and thus compensation is required. In the present embodiment, the compensation value of the attenuation caused by the low temperature is obtained by subtracting the feedback clock signal (the CLK signal fed back within the plane) from the initial clock signal (the uncompensated CLK signal emitted by the LS IC). The CLK signal is compensated based on the compensation value, thereby offsetting the voltage attenuation caused by the low temperature, thereby enabling the TFT to be turned on normally.

[0053] Step S30, configuring the in-plane driving voltage according to the preset voltage threshold and the compensation value.

[0054] In this embodiment, the corresponding in-plane driving voltage of the display panel at various ambient temperatures can be simulated through preliminary experiments to determine the preset voltage threshold (for example, the voltage threshold required under normal conditions and the voltage threshold required under the lowest temperature). When the preset voltage threshold has been determined in advance and the compensation value required at the current ambient temperature has also been determined, the in-plane driving voltage suitable for the current ambient temperature can be accurately configured to ensure that the display panel can start normally.

[0055] In some feasible embodiments, the above step S30 may specifically include:

[0056] Step S31 , subtracting or adding the preset voltage threshold and the compensation value to obtain the in-plane driving voltage.

[0057] In this embodiment, it can be determined according to the specific situation whether to subtract the compensation value from the preset voltage threshold to obtain the in-plane driving voltage, or to add the compensation value to the preset voltage threshold to obtain the in-plane driving voltage.

[0058] In some feasible embodiments, the preset voltage threshold includes a minimum voltage value and a maximum voltage value; specifically, step S31 may include:

[0059] Step S311: Add the minimum voltage value and the compensation value to obtain the in-plane driving voltage;

[0060] Or, step S312: Subtract the compensation value from the maximum voltage value to obtain the in-plane driving voltage.

[0061] In this embodiment, taking the addition of the minimum voltage value and the compensation value to obtain the in-plane driving voltage as an example, the VGH voltage compensation principle is described as follows:

[0062] Since the high potential of the CLK signal comes from the VGH voltage generated by the PMIC (Power Management Integrated Circuit), a relatively large VGH voltage is required to meet the compensation requirements when compensating the CLK signal. Therefore, an extreme VGH voltage can be found in advance through simulation experiments. As an example, if the required VGH voltage under normal conditions is 30V (which can be regarded as the minimum voltage value) and the lowest temperature specification is -20°C, a VGH voltage of 36V (which can be regarded as the maximum voltage value) is required to ensure the normal operation of the display panel. Then, the PMIC needs to generate two paths of VGH (one path is 30V and the other path is 36V) and supply them to the LS IC simultaneously. These two paths of VGH can be respectively marked as VGH1 (referring to 30V) and VGH2 (referring to 36V).

[0063] In this embodiment, the provision of the compensation value can be achieved by software or hardware, and this embodiment does not limit this. Taking the circuit implementation method as an example, when designing the circuit, a resistor string can be arranged between VGH1 and VGH2 in the LS IC. Then, the actual VGH voltage applied to CLK is obtained by voltage division of the resistor between VGH1 and VGH2. The size of the voltage-dividing resistor can be adjusted by code. Assuming it is set to 8 bits, the range of the code value is: 0 to 255. When the code value is 0, the required VGH = VGH1 = 30V; when the code value is 255, the required VGH = VGH2 = 36V. The voltage change for each step change of the code value is: (36V - 30V) / 255 = 23.5mV. In actual application, when the high voltage of CLK is detected, for example, the high voltage of CLK is 28V (i.e., the in-plane feedback signal), then the difference from the conventional voltage of 30V (i.e., the reference signal) for starting the TFT is 2V (i.e., the compensation value). At this time, the code value fed back to the LS IC is 2V / 23.5mV = 85. The VGH voltage applied to CLK after voltage division by the resistor is 30V (the minimum voltage value is selected for the preset voltage threshold) + 85 * 23.5mV (the compensation value is obtained by voltage division of the resistor) = 32V (i.e., the in-plane driving voltage).

[0064] In this embodiment, a driving method for a display panel is provided. First, the CLK signal after passing through the in-plane routing is connected back to the LS IC through in-plane routing. Then, the LS IC compares the received in-plane feedback CLK signal with the signal sent by the LS IC. Finally, the compensation value is superimposed on the in-plane driving voltage through two pre-configured VGH voltages and a voltage-dividing circuit implemented by an adjustable voltage-dividing resistor, which can make the compensation timing more accurate and the compensation effect better. There is no need to use a thermistor to detect the ambient temperature, overcoming the defect that the low-temperature compensation effect is not accurate enough in the related art by detecting the temperature with a thermistor, so that the display panel can also be normally started in a low-temperature environment.

[0065] In some feasible embodiments, the in-plane feedback signal includes the measured temperature, and the reference signal includes a preset temperature threshold; the above step S20 may further include:

[0066] Step S22, comparing the measured temperature with the preset temperature threshold to obtain a comparison result, and determining the compensation value according to the comparison result.

[0067] In this embodiment, taking the in-plane feedback signal as the measured temperature obtained by a temperature sensor provided on the display panel as an example, the reference signal is the minimum value in the normal temperature range (i.e., the preset temperature threshold) that will not cause voltage attenuation and affect the normal startup of the display panel. The normal temperature range can be 0°C to 40°C, or 0°C to 45°C, or -10°C to 50°C, etc. This embodiment does not limit this. By comparing the two, the difference between the current temperature and the normal temperature range can be obtained, and then the compensation value can be determined based on the variation law of voltage decay with temperature.

[0068] In some feasible embodiments, step S22 may specifically include:

[0069] Step S220: Subtract the preset temperature threshold from the measured temperature to obtain a temperature difference, and determine the compensation value based on the preset comparison table and the temperature difference.

[0070] In this embodiment, subtracting the measured temperature from the preset temperature threshold can inform how much the measured temperature differs from the normal temperature range. The preset comparison table can be set in advance based on the voltage-versus-temperature change curve as shown in Figure 2 Therefore, when the temperature difference is known, the compensation value can be quickly determined based on the temperature difference and the preset comparison table.

[0071] In addition, an embodiment of the present application also proposes a driving device for a display panel.
