Technical Field

[0001] This application relates to the field of liquid crystal display technology, and in particular to a display control method, apparatus, device and medium. Background Technology

[0002] With the rapid development of LCD technology, monitor refresh rates are getting higher and higher. Reducing panel power consumption at high refresh rates is one of the technologies that the industry is racing to develop.

[0003] To reduce power consumption, a frame storage module needs to be added to the system-on-chip (SOC) to determine still portions of the image. Specifically, the SOC reads display data from the frame buffer module and compares the current frame's display data with the previous frame's display data to determine still images. Based on the still image determination result, frame rate control is achieved by adjusting the vertical blanking (Vblank) time. For example, ... Figure 1 As shown, by extending the Vblank time while keeping the active display time constant, the display frequency is reduced from 120 Hz to 60 Hz, thus achieving frame rate control. However, this method of achieving frame rate control by adjusting the Vblank time requires adding a frame storage module to the SOC, resulting in a complex architecture. Summary of the Invention

[0033] The adjusted refresh rate is determined as the panel refresh rate.

[0034] Secondly, this application provides a display control device, comprising:

[0054] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of this application. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0056] To address the complexity of panel architecture caused by existing technologies that use Vblank time to adjust refresh rate, this embodiment provides a display control method. This method uses overvoltage drive data to determine the image display state of the display panel, determines the panel refresh rate based on the image display state, and outputs a gate drive frame start signal according to the panel refresh rate. This allows the display panel to display the image based on the gate drive frame start signal, thus achieving frame rate control using the gate drive frame start signal. This eliminates the need for an additional frame storage module on the SOC, resulting in a simpler architecture compared to existing related technologies that use the SOC for still image detection.

[0057] Figure 2 This is a flowchart illustrating the steps of a display control method provided in an embodiment of this application. Figure 2 As shown, the display control method provided in this embodiment includes the following steps:

[0058] Step 210: Determine the target image frame for the display panel;

[0059] The target image frame can refer to the image frame that the display panel currently needs to display. Specifically, in this embodiment, during the display processing, the image frame that the display panel currently needs to process can be determined as the target image frame, that is, the current frame can be determined as the target image frame.

[0060] Step 220: Determine the image display state based on the overvoltage drive data corresponding to the target image frame;

[0061] Specifically, after determining the target image frame, this embodiment can obtain the overvoltage driving data corresponding to the target image frame, and use the overvoltage driving data to determine the image display state of the display panel. There is no need to add an additional frame storage module on the SOC. Compared with the existing related technologies that use the SOC to realize still image judgment, the architecture is simple.

[0062] The overvoltage drive data corresponding to the target image frame refers to the grayscale (voltage) drive data generated by the timing controller for the target image frame. For example, it can be the overvoltage drive data generated by the timing controller using the overvoltage determination module by comparing the display data of the target image frame with that of the previous frame.

[0063] It should be noted that, in order to improve the response time, the timing controller inside the chip compares the data of the previous frame and the current frame. When the data difference between the previous frame and the current frame is large, an overvoltage grayscale (voltage) driving data is provided through the voltage driving module as overvoltage driving data to improve the response time from the initial grayscale to the target grayscale.

[0064] Step 230: Determine the panel refresh rate based on the image display status;

[0065] In practical implementation, different refresh rates can be preset for different image display states, serving as the preset target refresh rate corresponding to each image display state. In this embodiment, after determining the image display state, the corresponding preset target refresh rate can be obtained based on that state, and then set as the panel refresh rate.

[0066] Here, panel refresh rate refers to the refresh rate of the display panel. In one optional embodiment, determining the panel refresh rate based on the image display state may specifically include: obtaining a preset target refresh rate corresponding to the image display state; determining the target refresh rate as the panel refresh rate so that a gate drive frame start signal can be output based on the panel refresh rate, i.e., executing step 240.

[0067] Step 240: Output a gate drive frame start signal according to the panel refresh rate. The gate drive frame start signal is used to display the image on the display panel.

[0068] Specifically, in order to reduce panel power consumption at high refresh rates, this embodiment outputs a gate drive frame start signal according to the panel refresh rate after determining the panel refresh rate, so as to adjust the refresh rate using the gate drive frame start signal, so that the display panel displays the image according to the gate drive frame start signal, thereby achieving the purpose of refreshing rate control using the gate drive frame start signal, and solving the problem of complex panel architecture caused by the existing technology of adjusting the refresh rate using Vblank time.

[0069] In summary, this embodiment determines the target image frame of the display panel and determines the image display state of the display panel based on the overvoltage drive data corresponding to the target image frame. This eliminates the need to add an additional frame storage module to the SOC. Furthermore, it determines the panel refresh rate based on the image display state and outputs the gate drive frame start signal according to the panel refresh rate. This allows the display panel to display the image based on the gate drive frame start signal. Compared to existing related technologies that use the SOC to determine still images, this embodiment has a simpler architecture and uses the gate drive frame start signal to complete frame rate control, thus solving the problem of complex panel architecture caused by the existing technology of adjusting the refresh rate using Vblank time.

[0070] In an optional embodiment of this application, the image display state can be divided into a still image display state and a moving image display state; the still image display state refers to the display state when a still image is displayed; the moving image display state refers to the display state when a moving image is displayed. After determining the target image frame, the image display state of the display panel can be determined to be a still image display state by detecting whether the overvoltage driving data corresponding to the target image frame meets the preset still image display conditions. Optionally, this embodiment determines the image display state based on the overvoltage driving data corresponding to the target image frame, which specifically includes: detecting the overvoltage driving data corresponding to the target image frame; if the overvoltage driving data meets the preset still image display conditions, determining the still image display state as the image display state; if the overvoltage driving data does not meet the preset still image display conditions, determining the moving image display state as the image display state.

[0071] As can be seen, in this embodiment, when the overvoltage driving data meets the preset still image display conditions, the still image display state is determined as the image display state of the display panel. When the overvoltage driving data does not meet the preset still image display conditions, the moving image display state is determined as the image display state of the display panel. This allows the refresh rate of the display panel to be adjusted according to the image display state. For example, when the image display state is a still image display state, the refresh rate of the display panel is adjusted according to the preset target refresh rate corresponding to the image display state until the adjusted refresh rate reaches the target refresh rate. The adjusted refresh rate is then determined as the panel refresh rate, so that the gate drive frame start signal can be output according to the panel refresh rate to achieve frequency reduction display.

[0072] In an optional embodiment of this application, the preset target refresh rate for the still image display state is lower than the preset target refresh rate for the running image display state, so as to ensure the display effect of the running image while saving panel power consumption. As an example of this application, in order to ensure the display effect of the running image, the preset target refresh rate for the moving image display state can be set to 120Hz according to the display resolution of the display panel, and the preset target refresh rate for the still image display state can be set to a refresh rate lower than 120Hz, such as setting the preset target refresh rate for the still image display state to 30Hz, so as to achieve frequency reduction display when displaying still images and achieve the purpose of saving power consumption.

[0073] In one optional embodiment of this application, determining the panel refresh rate based on the image display state may specifically include: when the image display state is a still image display state, detecting whether the display refresh rate of the display panel exceeds a preset target refresh rate corresponding to the still image display state; if the display refresh rate exceeds the target refresh rate, adjusting the refresh rate of the display panel according to the target refresh rate to obtain an adjusted refresh rate; and determining the adjusted refresh rate as the panel refresh rate. This allows for the determination of the preset target refresh rate corresponding to the still image display state as the panel refresh rate when overvoltage drive data meets preset still image display conditions, thereby achieving frequency reduction during still image display and reducing panel power consumption.

[0074] Furthermore, in this embodiment, when the overvoltage drive data does not meet the preset still image display conditions, the preset target refresh rate corresponding to the motion image display state can be determined as the panel refresh rate to restore high-frequency display when displaying motion images and ensure the motion image display effect.

[0075] Optionally, this embodiment determines the panel refresh rate based on the image display state, specifically including: when the image display state is a moving image display state, detecting whether the display refresh rate of the display panel is lower than a preset target refresh rate corresponding to the moving image display state; when the display refresh rate is lower than the preset target refresh rate corresponding to the moving image display state, adjusting the refresh rate of the display panel according to the target refresh rate to obtain an adjusted refresh rate; and determining the adjusted refresh rate as the panel refresh rate. Specifically, in this embodiment, when the image display state is a moving image display state, the refresh rate of the display panel is adjusted according to a preset target refresh rate corresponding to the image display state until the adjusted refresh rate reaches the preset target refresh rate corresponding to the moving image display state, and the adjusted refresh rate is determined as the panel refresh rate. This allows the panel refresh rate to be adjusted to the preset target refresh rate corresponding to the moving image display state, so that a gate drive frame start signal can be output according to the panel refresh rate to achieve high-frequency display during moving image display and ensure the moving image display effect.

[0076] Furthermore, to prevent frequency switching, this embodiment can determine the overvoltage duration corresponding to the overvoltage driving data, so that when the overvoltage duration reaches a certain threshold, the overvoltage driving data is considered to meet the preset still image display conditions. Optionally, the detection of the overvoltage driving data corresponding to the target image frame in this embodiment may specifically include: acquiring the overvoltage driving data corresponding to the target image frame; determining the overvoltage duration using the overvoltage driving data; determining that the overvoltage driving data meets the preset still image display conditions when the overvoltage duration reaches the preset duration; and determining that the overvoltage driving data does not meet the preset still image display conditions when the overvoltage duration does not reach the preset duration.

[0077] The preset duration refers to a pre-set time threshold, which can be used to determine whether the overvoltage drive data meets the preset still image display conditions to prevent frequency switching. For example, if the preset duration is set to 60 seconds, and no image change is detected within 60 seconds, the panel refresh rate can be reduced to reduce power consumption; while if an image change is detected, the panel refresh rate can be increased to ensure that moving image features are displayed and improve the display effect.

[0078] The overvoltage duration can refer to the duration during which the overvoltage driving data exceeds a preset certain driving data threshold. For example, if the overvoltage driving data starts to exceed the preset certain driving data threshold at time point A, and then starts to decrease after a certain period of time, and if the overvoltage driving data decreases to less than the preset certain driving data threshold at time point B, then the duration from time point A to time point B can be determined as the overvoltage duration, i.e., overvoltage duration = BA.

[0079] In an optional embodiment of this application, determining the overvoltage duration using the overvoltage driving data specifically includes: determining whether the overvoltage driving data is greater than a preset voltage data; if the overvoltage driving data is greater than the preset voltage data, recording the duration corresponding to the overvoltage driving data; and using the recorded duration as the overvoltage duration. The preset voltage data can be used to determine whether an image is displayed as a static or dynamic image. For example, if the overvoltage driving data corresponding to a target image frame is greater than the preset voltage data, the image of the target image frame is determined to be a dynamic image; and if the overvoltage driving data corresponding to the target image frame is not greater than the preset voltage data, the image of the target image frame is determined to be a static image.

[0080] The embodiments of this application are described below by way of example. However, it should be noted that the implementation of this application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of this application.

[0081] As an example of this application, when the overall architecture of the display panel includes a timing control chip, the data accessed by the overvoltage drive module of the timing control chip can be compared to determine whether the target image frame is a still image or a moving image, thereby determining the image display state and modifying the refresh rate of the display panel based on the image display state.

[0082] The overvoltage drive module of the timing control chip can store display data in the frame buffer module. It can also compare the data of the current frame with the data of the previous frame, look up the overvoltage drive lookup table to obtain the corresponding overvoltage drive data, and send it to the display screen. This allows the display screen to display images based on the overvoltage drive data, thus making the previous data frequency and the display frequency consistent. In other words, the frequency at which the overvoltage module of the timing control chip accesses display data is consistent with the frequency at which the display screen displays images based on the display data.

[0083] For example, such as Figure 3As shown, the overvoltage driving module can receive display data through the data receiving module and store the display data in the frame buffer module Frame buffer. When the overvoltage driving module receives the display data of the current frame, it can determine the current frame as the target image frame of the display panel, store the display data of the current frame in the frame buffer module Frame buffer, and extract the display data of the previous frame from the frame buffer module Frame buffer to compare the display data of the previous frame with the display data of the current frame, so as to implement still image judgment, that is, determine whether the image of the current frame is a still image display or a moving image display through data comparison, and then determine the image display state, and modify the panel refresh rate based on the image display state.

[0084] Specifically, when the still image data condition is Max(dataf_cur - datafe_pre) < d_th, the method of modifying the panel refresh rate can specifically include: the overvoltage driving module judges the data change between the previous frame and the current frame to determine whether the data change is less than the preset threshold d_th. Thus, when it is judged that the data change is less than the preset threshold d_th, it is considered that the data change meets the still image data condition, and the time is recorded to record the overvoltage duration; when the recorded time is greater than the preset time T, the display frequency is reduced. For example, when the preset target refresh rate corresponding to the moving image display state is 120Hz and the preset target refresh rate corresponding to the still image display state is 30Hz, the panel refresh rate can first drop from 120Hz to 60Hz, and then from 60Hz to the preset target refresh rate 30Hz corresponding to the still image display state, as Figure 4 shown; when it is judged that the data change is not less than the preset threshold d_th, it is considered that the data change does not meet the still image data condition, and further it is considered that the image of the current frame is a dynamic image display, that is, the dynamic image display state is determined as the image display state. Subsequently, the panel refresh rate can be determined based on the preset target refresh rate corresponding to this image display state. For example, the panel refresh rate can be adjusted from 30Hz to 120Hz, as Figure 4 shown, so as to achieve the purpose of restoring high-frequency display when it is judged that the image of the current frame is a dynamic image.

[0085] It should be noted that the preset threshold d_th can be used to determine whether the data change meets the conditions of still image data. Specifically, the specific value of the preset threshold d_th can be set according to the judgment requirements of still images, and this implementation does not limit it; in Max(dataf_cur - datafe_pre) < d_th, dataf_cur can refer to the display data of the current frame, and in Max(dataf_cur - datafe_pre) < d_th, datafe_pre can refer to the display data of the previous frame, so that Max(dataf_cur - datafe_pre) can be used to represent the data change between the previous frame and the current frame.

[0086] The gate drive frame start signal is the start signal STV of the gate drive circuit of the display panel, and this start signal STV is the frame start signal for gate drive. If there is no start signal STV, the display panel behind the timing control chip will not be driven. Specifically, when the timing control chip does not provide the start signal STV, the gate drive circuit of the display panel does not work, and the display frame corresponding to the display panel is not refreshed, thereby reducing power consumption. For example, as Figure 5 shown, when the panel refresh rate is 120 Hz, the timing control chip can output the start signal STV to the gate drive circuit at a frequency of 120 Hz, so that the display panel refreshes the image screen at a frequency of 120 Hz based on this start signal STV; when the panel refresh rate is 60 Hz, the timing control chip can output the start signal STV to the gate drive circuit at a frequency of 60 Hz, so that the display panel refreshes the image screen at a frequency of 60 Hz based on this start signal STV; and when the panel refresh rate is 30 Hz, the timing control chip can output the start signal STV to the gate drive circuit at a frequency of 30 Hz, so that the display panel refreshes the image screen at a frequency of 30 Hz based on this start signal STV.

[0087] It can be seen that this example can use the existing overvoltage drive module of the timing control chip to judge image stillness and complete frame rate control by controlling the gate drive frame start signal STV. Compared with the existing architecture, there is no need to add an additional frame storage module on the SOC to judge image motion / stillness, and the architecture is simple.

[0088] In summary, this embodiment determines the image display state of the display panel by utilizing overvoltage drive data, eliminating the need for an additional frame storage module on the SOC. Compared to existing related technologies that use the SOC to determine still images, this embodiment has a simpler architecture. Furthermore, this embodiment determines the panel refresh rate based on the image display state and outputs a gate drive frame start signal according to the panel refresh rate, enabling the display panel to display the image based on the gate drive frame start signal. This achieves the purpose of frame rate control using the gate drive frame start signal, solving the problem of complex panel architecture caused by the existing technology of adjusting the refresh rate using Vblank time.

[0089] It should be noted that, for the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should know that the embodiments of this application are not limited to the described order of actions, because according to the embodiments of this application, some steps may be performed in other orders or simultaneously.
