DETAILED DESCRIPTION

[0044] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0046] With the rapid advancement of science and technology, the field of display technology has ushered in unprecedented development. Among them, liquid crystal display panels have dominated computer devices such as laptops, tablets and monitors due to their low power consumption, high miniaturization and excellent light and thin characteristics, greatly enriching the user's visual experience. However, as users' expectations for display quality continue to increase, the performance of liquid crystal display panels under extreme environmental conditions has become a new focus. Especially in low-temperature environments, liquid crystal molecules become more viscous due to lower temperatures, which directly leads to a significant increase in intermolecular friction. This physical change significantly inhibits the free movement and rapid rotation of liquid crystal molecules, which in turn causes the response time of the liquid crystal display panel to be sharply extended, and the picture update speed is slowed down, which is ultimately reflected in the display screen's smearing, blurring and even color distortion, seriously damaging the overall display quality and user experience. In other words, how to effectively overcome the adverse effects of low temperature on the performance of liquid crystal display panels and improve their display clarity and response speed in low-temperature environments has become a key technical problem that needs to be overcome in the current research and development of display technology.

[0047] Therefore, in order to solve the technical problem of poor display quality of liquid crystal display panels in low temperature environments, the present application proposes a heating circuit and a heating control method thereof, a display panel and a computer.

[0048] Based on this, the embodiment of the present application provides a heating circuit, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the heating circuit of the present application.

[0049] Reference Figure 1The present application provides a heating circuit. In a first embodiment of the heating circuit, the heating circuit is applied to a display panel. The heating circuit includes: a temperature acquisition module 10, a control module 20, a switch module 30, a pixel driving module 40 and a heating module 50; the temperature acquisition module 10 is electrically connected to a first side of the control module 20, a second side of the control module 20 is electrically connected to a controlled side of the switch module 30, and the pixel driving module 40 is electrically connected to the heating module 50 through the switch module 30.

[0050] In this embodiment, the present application integrates the heating circuit into the display panel, and collects the current ambient temperature of the display panel in the display mode in real time through the temperature acquisition module 10; then the control module 20 intelligently adjusts the switch module 30 according to the collected current ambient temperature, thereby accurately controlling the pixel driving module 40 to supply power to the heating module 50 in a low temperature environment, thereby realizing active adjustment of the temperature of the liquid crystal display panel, thereby effectively solving the problem of decreased display quality caused by the slowdown of liquid crystal molecular movement in a low temperature environment.

[0051] It should be noted that the pixel driving module 40 provided in the present application can be understood as a module that provides necessary driving signals and voltages to each pixel point in the display panel to control the luminous state or color change of the pixel point.

[0052] The control module 20 is used to receive the current ambient temperature sent by the temperature acquisition module 10, and determine the average ambient temperature of the display panel based on the current ambient temperature. When the average ambient temperature matches a preset low temperature threshold, a switch conduction signal is output to the switch module 30.

[0053] In this embodiment, the current ambient temperature of the display panel in the display mode is collected in real time by the temperature acquisition module 10; next, according to the electrical connection between the temperature acquisition module 10 and the first side of the control module 20, the control module 20 provided in the present application can receive the current ambient temperature fed back by the temperature acquisition module 10 in real time, and can accurately calculate the average ambient temperature of the environment in which the display panel is located based on the current ambient temperature, and the control module 20 can quickly and accurately determine whether the display panel is in a low temperature state requiring heating based on the average ambient temperature. Once it is confirmed that the average ambient temperature matches the preset low temperature threshold, the control module 20 immediately outputs a switch conduction signal to the switch module 30, triggering the start-up of the heating module 50, thereby timely and effectively counteracting the adverse effects of low temperature on the liquid crystal display performance, ensuring that the display panel can still maintain a high-quality display effect in a low temperature environment.

[0054] It should be noted that the preset low temperature threshold can be customized according to application requirements. For example, the preset low temperature threshold can be 25° C. The above is only one implementation method of the present application, and the present application does not make any limitation here.

[0055] The switch module 30 is used to connect the connection link from the pixel driving module 40 to the heating module 50 according to the switch conduction signal output by the control module 20, so that the heating module 50 can access the driving voltage of the pixel driving module 40 to heat the display panel.

[0056] In this embodiment, when the control module 20 detects that the average value of the ambient temperature is lower than the preset low temperature threshold and outputs a switch conduction signal accordingly, the switch module 30 can respond quickly and instantly establish a connection link between the pixel driving module 40 and the heating module 50, ensuring that the heating module 50 can be seamlessly connected to the power supply system of the pixel driving module 40, and the voltage originally used by the pixel driving module 40 to power the display pixels is used to heat the display panel, thereby effectively improving the working performance of the display panel in a low temperature environment without adding additional power burden. In other words, the intelligent and efficient heating circuit set by the present application not only ensures the clarity and color accuracy of the display picture, but also prolongs the service life of the display panel, bringing a more stable and reliable visual experience to the user.

[0057] Further, in some feasible embodiments, referring to Figure 2 , Figure 2 The cross-sectional schematic diagram of the display panel involved in an embodiment of the heating circuit of the present application. The display panel includes a display area 100, the display area 100 includes a color filter substrate 101 and an array substrate 102 arranged opposite to each other, and a liquid crystal layer 103 arranged between the color filter substrate 101 and the array substrate 102; the heating module 50 includes a first heat-conducting layer 51 and a second heat-conducting layer 52, the first heat-conducting layer 51 is arranged on a side of the color filter substrate 101 away from the liquid crystal layer 103, and the second heat-conducting layer 52 is arranged on a side of the array substrate 102 away from the liquid crystal layer 103; wherein the first heat-conducting layer 51 is the same as the second heat-conducting layer 52; the first heat-conducting layer 51 and the second heat-conducting layer 52 are both full-surface transparent heating electrodes.

[0058] In this embodiment, by integrating the first heat-conducting layer 51 and the second heat-conducting layer 52 as the entire transparent heating electrode, which are respectively arranged on the outer sides of the color filter substrate 101 and the array substrate 102 (i.e., the side of the color filter substrate 101 away from the liquid crystal layer 103 and the side of the array substrate 102 away from the liquid crystal layer 103), not only uniform and efficient heating of the liquid crystal layer 103 and its peripheral components is achieved, the response speed and display effect of the display panel in a low temperature environment are effectively improved, the light transmittance of the display panel is maintained, the clarity and brightness of the picture are ensured, the complexity of the heating module 50 is simplified, and a more stable and reliable visual experience is provided to users.

[0059] Further, in some other feasible embodiments, referring to Figure 3 , Figure 3 The display panel frame diagram of an embodiment of the heating circuit of the present application is shown in FIG. The display panel further includes a non-display area 200100, the non-display area 200100 and the display area 100 are arranged in the same layer, and the non-display area 200100 is arranged near the display edge of the display area 100; the temperature acquisition module 10 includes a plurality of temperature sensors, and each of the temperature sensors is evenly arranged in the sensing layer of the non-display area 200100 at a preset interval.

[0060] In this embodiment, the present application not only optimizes the overall structure of the display panel, but also fully utilizes the space of the non-display area 200100 by cleverly setting the non-display area 200100 at the edge of the display area 100 and laying it out in the same layer as the display area 100. At the same time, multiple temperature sensors are evenly arranged on the sensing layer of the non-display area 200100 and arranged at preset intervals, so that the temperature acquisition module 10 integrating multiple temperature sensors can accurately and comprehensively monitor the temperature changes of key parts of the display panel, which not only improves the accuracy and real-time performance of the temperature acquisition of the heating circuit, but also enhances the thermal management capability of the display panel under complex environmental conditions, helps to protect the liquid crystal layer 103 and other sensitive components from extreme temperatures, thereby extending the service life of the display panel and improving the user experience.

[0061] It should be noted that Figure 3 The solid circle shown represents a temperature sensor, and the number of temperature sensors can be customized according to application requirements, and this application does not impose any restrictions here.

[0062] Furthermore, in some feasible embodiments, the display panel also includes a display mainboard, the control module 20, the switch module 30 and the pixel driving module 40 are all arranged on the display mainboard, and the display mainboard is arranged on a side close to the sensing layer.

[0063] In this embodiment, the present application integrates and arranges the control module 20, the switch module 30 and the pixel driving module 40 on the display main board, and the layout of the display main board close to the sensing layer simplifies the internal structure of the display panel, reduces the connection lines between components, and thus improves the stability and efficiency of signal transmission. In addition, the present application arranges the display main board on the side close to the sensing layer, so that the control module 20 can more directly and quickly obtain the temperature data uploaded by the sensing layer (i.e., the current ambient temperature of the display panel), and then make a more rapid and accurate response, thereby enhancing the real-time performance and responsiveness of the display panel using the heating circuit.

[0064] Further, in some other feasible embodiments, referring to Figure 4 , Figure 4 This is a circuit diagram of an embodiment of the heating circuit of the present application. The control module 20 is a control chip, and the switch module 30 at least includes a first switch tube Q1, a second switch tube Q2, a first wire X1, and a second wire X2; the controlled end of the first switch tube Q1 is electrically connected to the controlled end of the second switch tube Q2, the first passage end of the first switch tube Q1 is electrically connected to the pixel driving module 40, the second passage end of the first switch tube Q1 is electrically connected to the second passage end of the second switch tube Q2, and the first passage end of the second switch tube Q2 is grounded; the controlled end of the first switch tube Q1 is electrically connected to the connection node of the controlled end of the second switch tube Q2, and is electrically connected to the signal end of the control chip; the second passage end of the first switch tube Q1 is electrically connected to the connection node of the second passage end of the second switch tube Q2, and is electrically connected to the input side of the first wire X1 and the input side of the second wire X2 respectively; the output side of the first wire X1 is electrically connected to the first heat-conducting layer 51, and the output side of the second wire X2 is electrically connected to the second heat-conducting layer 52.

[0065] In this embodiment, refer to Figure 4 In response to the information that the average value of the ambient temperature matches the preset low temperature threshold, the control chip outputs a switch conduction signal representing a high level to the switch module 30. At this time, the first switch tube Q1 is turned on and the second switch tube Q2 is turned off, so that the driving voltage provided by the pixel driving module 40 can be transmitted to the first heat conducting layer 51 and the second heat conducting layer respectively through the first switch tube Q1, so that the first heat conducting layer 51 and the second heat conducting layer can be synchronously provided. Figure 2The liquid crystal layer 103 in the display panel is heated, thereby effectively improving the display quality of the display panel in a low temperature environment. That is to say, when the control chip set in the present application detects that the average value of the ambient temperature matches the preset low temperature threshold, it can immediately respond to output a switch conduction signal representing a high level to activate the first switch tube Q1 in the switch module 30, while ensuring that the second switch tube Q2 is in a closed state. It is effectively achieved that when the average value of the ambient temperature of the display panel in the display mode is lower than the preset low temperature threshold, the electric energy provided by the pixel driving module 40 is automatically converted into the driving voltage required for thermal energy, and supplied to the first heat-conducting layer 51 and the second heat-conducting layer 52 respectively, thereby significantly improving the low temperature adaptability and heating efficiency of the display panel, and ensuring the normal operation of the display panel in a cold environment and the stability of display performance.

[0066] It should be noted that the first switch tube Q1 provided in the present application is an NPN transistor or an N-type MOS tube, and the second switch tube Q2 is a PNP transistor or a P-type MOS tube. Exemplarily, when the signal end of the control chip outputs a high level, the first switch tube Q1 is turned on and the second switch tube Q2 is turned off; when the signal end of the control chip outputs a low level, the first switch tube Q1 is turned off and the second switch tube Q2 is turned on.

[0067] In another embodiment, when the heating module 50 heats the display panel, the temperature acquisition module 10 provided in the present application continuously acquires the panel temperature of the display panel, and uploads the panel temperature to the control module 20 according to the electrical connection between the temperature acquisition module 10 and the control module 20, and accurately calculates the panel average temperature of the display panel according to the panel temperature, until it is detected that the panel average temperature reaches a preset normal display temperature threshold, and then outputs a switch disconnection signal representing a low level to the switch module 30, so that the first switch tube Q1 in the switch module 30 is turned off and the second switch tube Q2 is turned on, thereby quickly pulling down the voltage of the second path end of the first switch tube Q1 to the ground end, achieving the purpose of automatically disconnecting the electrical connection between the pixel driving module 40 and the heating module 50, that is, cutting off the power supply provided by the pixel driving module 40 to the heating module 50, thereby promptly stopping the operation of the heating module 50 to heat the display panel, effectively avoiding potential damage to the display panel caused by overheating, ensuring that the display panel operates stably under optimal temperature conditions, and significantly improving the display quality of the display panel.

[0068] It should be noted that the preset normal display temperature threshold can be customized according to application requirements, and the preset normal display temperature threshold is greater than the preset low temperature threshold. For example, the preset normal display temperature threshold is 28°C. The above is only one implementation of the present application, and the present application does not impose any limitations hereon.

[0069] In summary, the present application provides a heating circuit and a heating control method thereof, a display panel and a computer, which significantly improve the display quality of a liquid crystal display panel using the heating circuit in a low temperature environment. Specifically, the heating circuit provided in the present application integrates a temperature acquisition module 10, a control module 20, a switch module 30, a pixel driving module 40 and a heating module 50. First, the current ambient temperature of the display panel in the display mode is collected in real time through the temperature acquisition module 10; next, according to the electrical connection between the temperature acquisition module 10 and the first side of the control module 20, the control module 20 can quickly receive the current ambient temperature sent by the temperature acquisition module 10, and can accurately obtain the average ambient temperature of the display panel according to the current ambient temperature. Once it is confirmed that the average ambient temperature matches the preset low temperature threshold (that is, the display panel is in a low temperature environment), the control module 20 immediately sends a switch conduction signal to the switch module 30, so that the switch module 30 can connect the connection link from the pixel driving module 40 to the heating module 50 according to the switch conduction signal, so that the heating module 50 can directly access the driving voltage of the pixel driving module 40 in a low temperature environment to heat the display panel accurately, thereby effectively reducing the viscosity and friction of the liquid crystal molecules, accelerating the rotation speed of the liquid crystal molecules, and significantly shortening the response time of the liquid crystal display panel, ensuring that the liquid crystal display panel can maintain excellent display quality even in a severe cold environment.

[0070] Further, based on the above-mentioned first embodiment of the present application, a second embodiment of the heating circuit of the present application is proposed, referring to Figure 5 , Figure 5 This is a flow chart of the second embodiment of the heating control method of the present application.

[0071] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a device that can realize the above functions (such as a display panel applied to a heating circuit), etc. The following takes a computer as an example to illustrate this embodiment and the following embodiments.

[0072] The present application provides a heating control method, which is applied to any of the above-mentioned heating circuits, and the heating control method includes:

[0073] Step S10: receiving the current ambient temperature sent by the temperature acquisition module 10 through the control module 20, and determining the average ambient temperature of the display panel according to the current ambient temperature.

[0074] In this embodiment, the current ambient temperature of the display panel in the display mode is collected in real time by the temperature collection module 10; next, based on the electrical connection between the temperature collection module 10 and the first side of the control module 20, the control module 20 provided in the present application can receive the current ambient temperature fed back by the temperature collection module 10 in real time, and can accurately calculate the average ambient temperature of the environment in which the display panel is located based on the current ambient temperature.

[0075] Step S20 : ​​when the ambient temperature average matches the preset low temperature threshold, the control module 20 outputs a switch-on signal to the switch module 30 .

[0076] In this embodiment, the control module 20 can quickly and accurately determine whether the display panel is in a low-temperature state that requires heating based on the average ambient temperature. Once it is confirmed that the average ambient temperature matches the preset low-temperature threshold, the control module 20 immediately outputs a switch-on signal to the switch module 30, triggering the start-up of the heating module 50, thereby timely and effectively counteracting the adverse effects of low temperature on the liquid crystal display performance, ensuring that the display panel can still maintain a high-quality display effect in a low-temperature environment.

[0077] Step S30: after determining that the switch module 30 connects the connection link from the pixel driving module 40 to the heating module 50 according to the switch conduction signal output by the control module 20 , the display panel is heated by connecting the driving voltage of the pixel driving module 40 through the heating module 50 .

[0078] In this embodiment, when the control module 20 detects that the average value of the ambient temperature is lower than the preset low temperature threshold and outputs a switch conduction signal accordingly, the switch module 30 can respond quickly and instantly establish a connection link between the pixel driving module 40 and the heating module 50, ensuring that the heating module 50 can be seamlessly connected to the power supply system of the pixel driving module 40, and the voltage originally used by the pixel driving module 40 to power the display pixels is used to heat the display panel, thereby effectively improving the working performance of the display panel in a low temperature environment without adding additional power burden. In other words, the intelligent and efficient heating circuit set by the present application not only ensures the clarity and color accuracy of the display picture, but also prolongs the service life of the display panel, bringing a more stable and reliable visual experience to the user.

[0079] Furthermore, in some feasible embodiments, the above step S10: determining the average value of the ambient temperature of the display panel according to the current ambient temperature, may also include the following implementation step S101.

[0080] Step S101: performing mean processing on the current ambient temperature according to a preset mean processing function to obtain the mean ambient temperature of the display panel; wherein,

[0081] The mean processing function is:

[0082] μ represents the average ambient temperature of the display panel, represents the transposed value T corresponding to the temperature weight vector of the i-th temperature sensor, m represents the total number of all the temperature sensors, and h i represents the current ambient temperature of the i-th temperature sensor, b μ is the mean compensation amount corresponding to the mean value of the ambient temperature.

[0083] Furthermore, in some other feasible embodiments, after the above step S10: determining the average value of the ambient temperature of the display panel according to the current ambient temperature, the heating control method may further include the following implementation steps A10 to A30.

[0084] Step A10: Detect whether the average value of the ambient temperature is less than a preset low temperature threshold;

[0085] Step A20: If the ambient temperature average is less than the low temperature threshold, determining that the ambient temperature average matches the low temperature threshold;

[0086] Step A30: If the ambient temperature average is greater than or equal to the low temperature threshold, it is determined that the ambient temperature average does not match the low temperature threshold, and the current ambient temperature of the display panel is collected by the temperature detection module at a preset collection frequency.

[0087] In this embodiment, it is first detected whether the mean value of the ambient temperature is lower than the preset low temperature threshold, so that the control module 20 can quickly identify the risk that the display panel may be in a low temperature environment. Once it is confirmed that the mean value of the ambient temperature is lower than the preset low temperature threshold, it is determined that the mean value of the ambient temperature matches the low temperature threshold, and the control module 20 automatically outputs a switch conduction signal to enable the switch module 30 to connect the connection link from the pixel driving module 40 to the heating module 50, so that the heating module 50 can heat the display panel. To prevent low temperature from affecting the normal display of the display panel, thereby effectively improving the display quality of the display panel. On the contrary, if the mean value of the ambient temperature is not lower than the low temperature threshold, the current ambient temperature of the display panel is continuously collected by the temperature detection module according to the preset collection frequency, and the step of "receiving the current ambient temperature sent by the temperature collection module 10 through the control module 20, and determining the mean value of the ambient temperature of the display panel based on the current ambient temperature" is returned to execute.

[0088] In summary, the present application provides a heating circuit and a heating control method thereof, a display panel and a computer, which significantly improve the display quality of a liquid crystal display panel using the heating circuit in a low temperature environment. Specifically, the heating circuit provided in the present application integrates a temperature acquisition module 10, a control module 20, a switch module 30, a pixel driving module 40 and a heating module 50. First, the current ambient temperature of the display panel in the display mode is collected in real time through the temperature acquisition module 10; next, according to the electrical connection between the temperature acquisition module 10 and the first side of the control module 20, the control module 20 can quickly receive the current ambient temperature sent by the temperature acquisition module 10, and can accurately obtain the average ambient temperature of the display panel according to the current ambient temperature. Once it is confirmed that the average ambient temperature matches the preset low temperature threshold (that is, the display panel is in a low temperature environment), the control module 20 immediately sends a switch conduction signal to the switch module 30, so that the switch module 30 can connect the connection link from the pixel driving module 40 to the heating module 50 according to the switch conduction signal, so that the heating module 50 can directly access the driving voltage of the pixel driving module 40 in a low temperature environment to heat the display panel accurately, thereby effectively reducing the viscosity and friction of the liquid crystal molecules, accelerating the rotation speed of the liquid crystal molecules, and significantly shortening the response time of the liquid crystal display panel, ensuring that the liquid crystal display panel can maintain excellent display quality even in a severe cold environment.
