[0041] To make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0042] The research and development idea of the present application includes: for high display image quality, the charging amplitude of pixels in the display product can be increased to shorten the display response time and thus achieve a high refresh rate of the display screen. More commonly, the display driving method is to perform start charging or stop charging control with the start and end times of each frame of the screen as the reference system. However, both charging and discharging have a process. Based on the existing display driving reference system, the discharging action only starts at the end time of each frame of the screen, and there will inevitably be a certain delay in the discharging process, that is, there is an overlap in time between the discharging process of the previous frame of the screen and the charging process of the next frame of the screen, which results in an over-driving phenomenon, that is, a trailing or color trailing phenomenon, seriously affecting the image quality.

[0043] The logic board, display panel, and display driving method provided by this application aim to solve the above technical problems in the prior art.

[0044] The following uses specific embodiments to elaborate in detail on the technical solutions of this application and how the technical solutions of this application solve the above technical problems. It should be noted that the following embodiments can refer to, draw on, or combine with each other. For the same terms, similar features, and similar implementation steps in different embodiments, they will not be described repeatedly.

[0045] An embodiment of this application provides a display driving method. The schematic flowchart of this display driving method is as Figure 1 shown, including the following steps S101 - S103:

[0046] S101: Generate or receive a reference signal sequence.

[0047] In this step S101, the reference signal sequence can be generated by an internal functional module of an actuator (such as any of the logic boards provided below), or can be generated by related components external to the actuator (such as a digital board provided below).

[0048] Optionally, generating the reference signal sequence includes: sequentially generating at least two reference sub - signals, with a unit interval time between two adjacent reference sub - signals.

[0049] The reference signal sequence adopts the signal sequence rule provided in this embodiment. The time interval between every two adjacent reference sub - signals is equal, which is the unit interval time, facilitating determining the specified interval time by detecting the number of reference sub - signals in subsequent steps.

[0050] Optionally, the reference signal sequence includes: a clock signal sequence.

[0051] In this embodiment, the clock signal sequence can be generated by an internal functional module of the actuator that executes the above step S101, or can be generated by related components external to the actuator. Using the clock signal sequence as the reference signal sequence has the advantage of easy material acquisition and is conducive to cost reduction.

[0052] Optionally, the reference signal sequence includes: a display data identification sequence.

[0053] In this embodiment, the display data identification sequence can be generated by related components external to the actuator that executes the above step S101. Using the display data identification sequence as the reference signal sequence can utilize the display data signal, without the need to additionally set up a dedicated functional module for generating the reference signal sequence, which is also conducive to cost reduction.

[0054] Optionally, the reference signal sequence includes: a clock signal sequence and a display data identification sequence.

[0055] In this embodiment, the synergistic effect of the clock signal sequence and the display data identification sequence can be utilized to provide a reference system for the charging process and the discharging process of the display driving. For example, the clock signal sequence is used as the reference system for the charging process of the display driving, and the display data identification sequence is used as the reference system for the discharging process of the display driving. During the synergistic effect process, a time correlation between the clock signal sequence and the display data identification sequence can be established; vice versa.

[0056] It should be noted that the above step S101 can be continuously executed normally, or can be started and executed under the condition of receiving the display data signal.

[0057] S102: Under the condition of receiving the display data signal, a start display driving signal is issued according to a reference sub-signal in the reference signal sequence.

[0058] In this step S102, it is determined that the display driving method can be started and executed by detecting the display data signal. This is beneficial for the executing mechanism not to occupy resources due to step S102 and its subsequent steps under the condition of not receiving the display data signal, effectively optimizing the resources of the executing mechanism, or saving energy and reducing costs.

[0059] Optionally, in the above step S102, issuing a start display driving signal according to a reference sub-signal in the reference signal sequence includes: issuing a start display driving signal according to the rising edge or the falling edge of a reference sub-signal.

[0060] S103: A stop display driving signal is issued according to another reference sub-signal at a specified interval time after a reference sub-signal; the specified interval time is less than the duration of the current frame of the picture.

[0061] In this step S103, a stop display driving signal can be issued based on another reference sub-signal whose time interval from the start moment of the charging process is less than the duration of the current frame of the picture, that is, the discharging moment can be advanced.

[0062] Optionally, issuing a stop display driving signal according to another reference sub-signal at a specified interval time after a reference sub-signal includes: issuing a stop display driving signal according to another reference sub-signal at an interval of a specified number after a reference sub-signal.

[0063] In this embodiment, based on a relatively regular reference signal sequence in which the time interval between every two adjacent reference sub-signals is equal, determining the specified interval time by detecting the number of reference sub-signals is beneficial for reducing the timing difficulty.

[0064] Optionally, a stop display driving signal is issued according to another reference sub-signal at a specified interval after a reference sub-signal, including: issuing a stop display driving signal according to the rising edge or falling edge of the another reference sub-signal.

[0065] Through the above steps S101-S103, a display driving method provided by the present application realizes using a reference signal sequence as a reference system for the charging process and discharging process of display driving. Specifically, two reference sub-signals with a specified interval time less than the duration of the current frame in the reference signal sequence are respectively used as the reference signal for issuing the start display driving signal and the reference signal for issuing the stop display driving signal. By advancing the discharging moment, that is, starting the discharging process of the current frame in advance at the end moment of each frame, it is beneficial to shorten the possible overlapping duration between the discharging process of the previous frame and the charging process of the next frame, and even completely avoid the aforementioned overlap, reduce the over-driving degree or overcome the over-driving phenomenon, effectively improve the possible trailing or color trailing phenomenon, and improve the display image quality.

[0066] It can be understood that during the process of the display panel performing display driving according to the display driving method of the foregoing steps S101-S103, due to the advancement of the discharging moment and the shortening of the charging time (the charging time is less than the duration of the current frame), therefore, during the charging process in which the display panel responds to the foregoing start display driving signal, it is necessary to appropriately increase the charging voltage to achieve a rated display effect. And the specific charging voltage value can be determined in advance during the experimental stage according to the evaluation test response time data and the dynamic video trailing situation.

[0067] Based on the same inventive concept, an embodiment of the present application provides a logic board 100. The schematic diagram of the frame structure of the logic board 100 is as Figure 2 shown, including: a reference signal module 110 and a display driving signal module 120.

[0068] The reference signal module 110 is used to generate or receive a reference signal sequence.

[0069] The display driving signal module 120 is connected to the reference signal module. The display driving signal module 120 is used to issue a start display driving signal according to a reference sub-signal in the reference signal sequence under the condition of receiving a display data signal, and issue a stop display driving signal according to another reference sub-signal at a specified interval after a reference sub-signal, and the specified interval time is less than the duration of the current frame.

[0070] In this embodiment, the reference signal module 110 can provide a reference signal sequence for the display driving signal module 120 as a reference system for the charging process and discharging process of display driving. The display driving signal module 120 uses two reference sub-signals in the reference signal sequence with a specified interval time less than the duration of the current frame as the reference signal for starting the emission of the display driving signal and the reference signal for stopping the emission of the display driving signal respectively. By advancing the discharging moment, that is, starting the discharging process of the current frame in advance at the end moment of each frame, it is beneficial to shorten the possible overlapping duration between the discharging process of the previous frame and the charging process of the next frame, and even completely avoid the aforementioned overlap, reduce the over-driving degree or overcome the over-driving phenomenon, effectively improve the possible trailing or color trailing phenomenon, and improve the display image quality.

[0071] In some possible implementation manners, such as Figure 3 shown, the reference signal module 110 includes: a clock module 111; the clock module 111 is connected to the display driving signal module 120.

[0072] In this embodiment, the clock module 111 can be used to generate a clock signal sequence, and use the clock signal sequence as the reference signal sequence to provide a reference signal sequence for the display driving signal module 120 as a reference system for the charging process and discharging process of display driving.

[0073] In some other possible implementation manners, such as Figure 4 shown, the reference signal module 110 includes: a display data identification receiving module 112; the display data identification receiving module 112 is connected to the display driving signal module 120.

[0074] In this embodiment, the display data identification receiving module 112 can be used to receive a display data identification sequence generated by related components (such as the digital board 210) outside the logic board 100, and use the display data identification sequence as the reference signal sequence, which can utilize the display data signal to provide a reference signal sequence for the display driving signal module 120 as a reference system for the charging process and discharging process of display driving.

[0075] In still some other possible implementation manners, such as Figure 5 shown, the reference signal module 110 includes: a clock module 111 and a display data identification receiving module 112. The clock module 111 and the display data identification receiving module 112 are respectively connected to the display driving signal module 120.

[0076] In this embodiment, the clock module 111 and the display data identification receiving module 112 can cooperate with each other. By utilizing the synergistic effect of the clock signal sequence and the display data identification sequence, a reference system is provided for the charging process and the discharging process of the display driving. For example, the clock signal sequence is used as the reference system for the charging process of the display driving, and the display data identification sequence is used as the reference system for the discharging process of the display driving. During the synergistic effect process, a time association can be established between the clock signal sequence and the display data identification sequence; vice versa.

[0078] The display driving signal module 120 in the digital board 210, the logic board 100, and the display panel 220 are connected in sequence.

[0079] In this embodiment, the digital board 210 can be used to generate display data signals, such as grayscale signals, etc.

[0080] The display panel 220 executes a display task according to the start display driving signal, the stop display driving signal generated by the logic board 100, and the forwarded display data signal.

[0081] In this embodiment, since the display device 200 includes any one of the logic boards 100 provided in the foregoing embodiments, its implementation principle and beneficial effects are similar, and will not be elaborated here.

[0082] In some possible implementation manners, as Figure 7 shown, the digital board 210 is also connected to the reference signal module 110 in the logic board 100.

[0083] In this embodiment, the reference signal module 110 in the logic board 100 can utilize the display data identification sequence in the display data signal sent by the digital board 210 as a reference signal sequence to provide a reference signal sequence for the display driving signal module 120 as a reference system for the charging process and the discharging process of the display driving.

[0084] Optionally, the digital board 210 is respectively connected to the display driving signal module 120 in the logic board 100 and the display data identification receiving module 112 in the reference signal module 110.
