Description

Technical Field

[0002] In a display system, a control terminal sends a vertical synchronization signal to a driving circuit to synchronize the display switching of each driving circuit. In practical applications, affected by the instability of the vertical synchronization signal, the vertical frequency may be too high or too low at certain moments. To cope with the frequency jitter of the vertical synchronization signal, the currently adopted solution usually is: a "buffer time" is forcibly reserved to turn off the light-emitting element during this period. This solution will cause a black field problem where the screen briefly turns black. This periodic black screen will disrupt the display coherence and cause problems such as visual flicker and ghosting. To achieve a better display effect, it is necessary to reduce the black field time.

[0047] In this embodiment, a display control method is provided. Figure 2 It is a flowchart of the display control method in this embodiment. As Figure 2 shown, the method includes the following steps:

[0048] Step S201: Obtain the display switching offset of the previous display.

[0049] Specifically, in display control, display data switching is usually performed on a field-by-field basis. Each field is divided into multiple sub-frames, and each sub-frame of each field can further include multiple scans in one round. The control end sends display data and control signals containing field synchronization flags to each driving circuit, so that each driving circuit synchronously performs display switching according to the field synchronization flags.

[0050] After the previous display ends and before the current field display starts, obtain the display switching offset of the previous display. The display switching offset corresponding to each display refers to the time offset between the start point of the current field synchronization and the end time point of the previous display. The display switching offset reflects whether the display switching time point of the current field is too early or too late. A negative display switching offset indicates that the display switching time point of the current field is too early, and a positive display switching offset indicates that the display switching time point of the current field is too late.

[0051] Step S202: Adjust the configuration parameters corresponding to the previous display according to the display switching offset and the preset threshold range to obtain the current configuration parameters; the configuration parameters include the single-scan display duration of the target sub-frame and the number of target sub-frames.

[0052] Specifically, before the current field display starts, adjust based on the comparison result of the display switching offset and the preset threshold range on the basis of the configuration parameters corresponding to the previous display to obtain the current configuration parameters. When the display switching offset is within the preset threshold range, there is no need to select the target sub-frame and adjust the single-scan display duration of any target sub-frame; when the display switching offset exceeds the preset threshold range, adjust the single-scan display duration and the number of target sub-frames, and use the adjusted single-scan display duration for the target sub-frame for display, and continue to use the single-scan display duration in the previous display for the sub-frames other than the target sub-frame in the current field.

[0053] The configuration parameters corresponding to each display include the single-scan display duration of the target sub-frame and the number of target sub-frames. Since each sub-frame of each field can further include multiple scans in one round, the single-scan display duration refers to the display duration of each single scan of each target sub-frame. The total duration of all single-scan display durations in a sub-frame is the display duration of the sub-frame. The target sub-frame refers to the sub-frame whose single-scan display duration needs to be adjusted in each display.

[0054] Among them, the preset threshold range can be preset and adjusted according to the actual display situation and requirements. Exemplarily, the preset threshold range can be counted by a clock. The preset threshold range is 0 to n clocks, where 0 is the lower limit value of the preset threshold range and n is the upper limit value of the preset threshold range, and the specific value is not limited.

[0055] Step S203: Send the current configuration parameters to each driving circuit to perform current field display control on the light-emitting elements through the driving circuits.

[0056] Specifically, under normal circumstances, the single-scan display duration of each sub-frame in each field display is a fixed value. The control terminal is configured to send the current configuration parameters to each driving circuit before the start of each field display to reconfigure the number of target sub-frames and the single-scan display duration of the target sub-frames in the current field. For the target sub-frames, the single-scan display duration is set individually according to the configuration parameters of the current field, and for the sub-frames other than the target sub-frames in the current field, the single-scan display duration in the previous field display is continued to be used. In addition, the control terminal also receives a control signal or a field synchronization signal containing a field synchronization flag and sends it to each driving circuit so that each driving circuit performs display control on the light-emitting elements according to the current configuration parameters and display data. Among them, the light-emitting elements include but are not limited to LEDs (light-emitting diodes), etc.

[0057] Through the above steps, before the start of each field display, based on the display switching offset of the previous field display, the configuration parameters of the current field can be adjusted on the basis of the configuration parameters corresponding to the previous field display, so as to configure each driving circuit according to the current configuration parameters, so that the driving circuit performs the current field display control on the light-emitting elements. Compared with the prior art solution of forcibly reserving buffer time, in this embodiment, the number of target sub-frames and the single-scan display duration can be adjusted in each field display to adapt to the field frequency jitter during the display process, and reduce the black field time and improve the display effect.

[0058] In some of the embodiments, obtaining the display switching offset of the previous field display in the above step S201 includes the following steps:

[0059] Determine the field synchronization flag according to the control signal of the current field; determine the display end time of the previous field display according to the control signal of the previous field; determine the display switching offset according to the field synchronization flag of the current field and the display end time of the previous field display.

[0060] Specifically, obtain the field synchronization flag according to the control signal sent by the control terminal to the driving circuit. The field synchronization flag can represent the field synchronization start time of the current field display. Further, the control signal can also be a field synchronization signal.

[0061] In addition, obtain the display end time of the previous field display according to the control signal of the previous field sent by the control terminal to the driving circuit. The display end time is the time when all sub-frames of the previous field are displayed. Further, the control signal can be an enable signal EN or a clock signal CLK.

[0062] Exemplarily, the control terminal sends an enable signal EN to each driving circuit, which is used to control the constant current output of the driving circuit, so that the driving circuit drives the corresponding light-emitting element to perform grayscale display according to the enable signal. When the enable signal is valid (such as low level), the light-emitting element is driven to be lit; when it is invalid (such as high level), the light-emitting element is driven to be turned off. When a field display is completely finished, the enable signal will become invalid (such as a transition from low to high), so that the display end moment of the previous field display can be determined according to the enable signal. In this case, the control terminal can obtain the display end moment of the previous field display according to the enable signal to be sent to the driving circuit.

[0063] Exemplarily, the control terminal sends a clock signal CLK to each driving circuit, which is used to control the constant current output pulse width of the driving circuit by counting the clock signal, so that the driving circuit drives the corresponding light-emitting element to perform grayscale display based on the clock signal. In this case, the control terminal counts according to the clock signal to be sent to the driving circuit, and then combines the display data of the previous field corresponding to the driving circuit to obtain the display end moment of the previous field display.

[0064] According to the difference between the field synchronization flag of the current field and the display end moment of the previous field display, the display switching offset of the previous field display is obtained. The display switching offset reflects the situation that the display switching time point of the current field is too early or too late. A negative display switching offset indicates that the display switching time point of the current field is too early, and a positive display switching offset indicates that the display switching time point of the current field is too late.

[0065] Through this embodiment, the display switching offset of the previous field display can be obtained before the start of each field display, so as to adjust the configuration parameters of the current field according to the display switching offset, and better adapt to the field frequency jitter in the current field.

[0066] In some of these embodiments, in step S202 above, adjusting the configuration parameters corresponding to the previous field display according to the display switching offset and the preset threshold range to obtain the current configuration parameters includes the following steps:

[0067] When the display switching offset exceeds the preset threshold range, adjust the single-scan display duration in preset unit time lengths, and calculate the corresponding target sub-frame number to obtain the current configuration parameters, or adjust the target sub-frame number, and calculate the corresponding single-scan display duration to obtain the current configuration parameters.

[0068] Specifically, the preset threshold range provides a certain allowable deviation range for the display switching bias, and the preset threshold range includes an upper limit value and a lower limit value. When the display switching bias exceeds the preset threshold range, that is, the display switching bias is greater than the upper limit value or less than the lower limit value, the single-scan display duration is adjusted by the preset unit duration based on the configuration parameters corresponding to the previous display, and then the corresponding target subframe number that needs to be adjusted is further calculated according to the preset threshold range, the display switching bias, etc., to obtain the current configuration parameters.

[0069] The preset unit duration can be counted by clocks, and for example, m clocks are recorded as one preset unit duration. Each scene can be adjusted by at least one preset unit duration, and the number of unit durations adjusted each time can be set according to the situation that the display switching deviation exceeds the preset threshold range. For example, when the display switching deviation exceeds the preset threshold range by a large amount, the adjustment is made by several preset unit durations; when the display switching deviation exceeds the preset threshold range by a small amount, the adjustment is made by one preset unit duration, and there is no specific limitation.

[0070] Further, when the display switching deviation is within the preset threshold range, the single scan display duration in the configuration parameters corresponding to the previous display is kept unchanged, and the target subframe number is reset to zero to obtain the current configuration parameters.

[0071] Specifically, when the display switching bias is within the preset threshold range, that is, the display switching bias is greater than or equal to the lower limit value and less than or equal to the upper limit value, it means that the display switching bias is within the allowable deviation range, and there is no need to adjust the single-scan display duration, nor is there any need to adjust any target subframe. Therefore, the number of target subframes is reset to zero, and the single-scan display duration of each subframe is maintained consistent with the configuration parameters of the previous display, so as to keep the display switching bias unchanged as much as possible.

[0072] Among them, when the display switching bias is less than the lower limit value, the single scan display time is shortened by at least one unit time; and the corresponding target subframe number is obtained according to the display switching bias, the lower limit value and the adjusted unit time number; when the display switching bias is greater than the upper limit value, the single scan display time is increased by at least one unit time; and the corresponding target subframe number is obtained according to the display switching bias, the upper limit value and the adjusted unit time number.

[0073] Specifically, when the display switching bias is less than the lower limit, the single scan display time is shortened by at least one unit time, and the target subframe number is calculated based on the difference between the display switching bias and the lower limit, and the number of unit time adjusted each time. When the display switching bias is greater than the upper limit, the single scan display time is increased by at least one unit time; the target subframe number is calculated based on the difference between the display switching bias and the upper limit, and the number of unit time adjusted each time.

[0074] Exemplarily, assume that the preset threshold range is from 0 to 10 unit durations, the lower limit value and the upper limit value are 0 and 10 respectively, and the display switching offset of the previous display is 15 unit durations. When increasing the single-scan display duration of the target sub-frame by 1 unit duration, according to the difference of 5 between the display switching offset and the upper limit value, and the number of unit durations adjusted each time, which is 1, the number of target sub-frames calculated is 5. When increasing the single-scan display duration of the target sub-frame by 5 unit durations, the number of target sub-frames calculated is 1.

[0075] In addition, based on the configuration parameters corresponding to the previous display, the number of target sub-frames can be determined first, and then according to the display switching offset, the number of target sub-frames and the preset threshold range, the corresponding single-scan display duration can be calculated to obtain the current configuration parameters.

[0076] Exemplarily, assume that the preset threshold range is from 0 to 10 unit durations, the lower limit value and the upper limit value are 0 and 10 respectively, and the display switching offset of the previous display is 14 unit durations. When the number of target sub-frames is determined to be 1 first, the single-scan display duration can be calculated to be 4 accordingly.

[0077] By adjusting the single-scan display duration in preset unit durations in this embodiment and then further calculating the number of target sub-frames whose single-scan display duration needs to be adjusted, the adjustment accuracy in each display is higher. At the same time, the number of target sub-frames can also be adjusted first, and then the corresponding single-scan display duration can be calculated. Such an adjustment method is more convenient. Both schemes can better adapt to the field frequency jitter and reduce the black field time at the same time.

[0078] In some of the embodiments, the above method further includes:

[0079] Based on the number of target sub-frames and a preset rule, before the current field display, the target sub-frames are pre-selected and determined from the sub-frames of the current field.

[0080] Specifically, before the current field display, the target sub-frames are pre-selected and determined from the sub-frames of the current field. The target sub-frames in each display can be specified by the control end through communication, or determined by a preset rule of the control end for the target sub-frames. The preset rule can be: when the number of target sub-frames is a, the last a sub-frames or the first a sub-frames of this field are the target sub-frames. The preset rule is not unique and is not specifically limited.

[0081] By pre-selecting and determining the target sub-frames from the sub-frames of the current field before the current field display in this embodiment, the driving circuit can set the single-scan display duration of the selected target sub-frames separately according to the configuration parameters, and thus perform display control to achieve fine-tuning of each display.

[0082] In some of the embodiments, the above method further includes:

[0083] After the display of the last sub-frame in the current field is completed and the field synchronization flag is detected, the display switches to the next field.

[0084] Specifically, the driving circuit is configured to perform a field switch only when the display of the last sub-frame in the current field is completed and the field synchronization flag is detected, which can provide double guarantees to ensure accurate synchronization and stable display between each field display.

[0085] The following describes and illustrates this embodiment through preferred embodiments.

[0086] Figure 3 is a flowchart of the display control method in this embodiment, as Figure 3 shown, the method includes the following steps:

[0087] Step S301, determine the field synchronization flag according to the control signal of the current field; determine the display end time of the previous field display according to the control signal of the previous field.

[0088] Step S302, determine the display switching offset according to the time difference between the field synchronization flag of the current field and the display end time of the previous field display.

[0089] Step S303, when the display switching offset is less than the lower limit value of the preset threshold range, shorten the single-scan display duration of the previous field display by at least one unit duration; and obtain the corresponding target sub-frame number according to the display switching offset, the lower limit value, and the number of adjusted unit durations, and determine the current configuration parameters.

[0090] Step S304, when the display switching offset is greater than the upper limit value of the preset threshold range, increase the single-scan display duration of the previous field display by at least one unit duration; and obtain the corresponding target sub-frame number according to the display switching offset, the upper limit value, and the number of adjusted unit durations, and determine the current configuration parameters.

[0091] Step S305, when the display switching offset is within the preset threshold range, keep the single-scan display duration in the configuration parameters corresponding to the previous field display unchanged, and clear the target sub-frame number to obtain the current configuration parameters.

[0092] Step S306, after the display of the last sub-frame in the current field is completed and the field synchronization flag is detected, switch to the next field display.

[0093] Figure 4 is a schematic diagram of the display control in this embodiment, as Figure 4 shown, the control terminal loads the field synchronization flag through an independent field synchronization signal and also sends an OE (Output Enable) signal. Figure 4Taking the number of target sub - frames in each display as 1, adjusting the single - scan display duration by one preset unit duration each time, and taking the nth sub - frame of each display as the target sub - frame as an example. In actual applications, the number of target sub - frames and the single - scan display duration need to be adjusted and determined according to the actual situation.

[0094] Taking Figure 4 the display period shown as an example, the control end is configured to re - configure the number of target sub - frames and the single - scan display duration of the target sub - frame to the driving circuit before the start of each display. Each display includes n sub - frames, each sub - frame includes s scans, and the display duration corresponding to each scan in the (m - 1)th field is the preset single - scan display duration A.

[0095] Before the start of the mth display, the control end calculates the display switching offset of the (m - 1)th field according to the field - sync flag of the mth field in the field - sync signal and the display end time of the (m - 1)th field in the enable signal corresponding to the driving circuit, that is, the time difference between the field - sync flag of the mth field and the display end time of the (m - 1)th field; thus, if the display switching offset of the (m - 1)th field is positive and not greater than the upper limit value of the preset threshold range, the control end sends the single - scan display duration A' = A of the target sub - frame and the number of target sub - frames is zero to the driving circuit before the start of the mth display, without selecting the target sub - frame and adjusting the single - scan display duration of the target sub - frame; if it is greater than the upper limit value of the threshold range, the control end sends the adjusted single - scan display duration of the target sub - frame as A' = A + 1 preset unit duration to the driving circuit before the start of the mth display, and obtains the number of target sub - frames according to the quantitative relationship between the display switching offset of the (m - 1)th field and the preset unit duration.

[0096] Before the start of the (m + 1)th display, the control end calculates the display switching offset of the mth field according to the field - sync flag of the (m + 1)th field in the field - sync signal and the display end time of the mth field in the enable signal corresponding to the driving circuit, that is, the time difference between the field - sync flag of the (m + 1)th field and the display end time of the mth field; thus, if the display switching offset of the mth field is negative and not less than the lower limit value of the preset threshold range, the control end sends the single - scan display duration A'' = A' of the target sub - frame and the number of target sub - frames is zero to the driving circuit before the start of the (m + 1)th display, without selecting the target sub - frame and adjusting the single - scan display duration of the target sub - frame; if it is less than the lower limit value of the preset threshold range, the control end sends the single - scan display duration of the target sub - frame as A'' = A' - 1 preset unit duration to the driving circuit before the start of the (m + 1)th display, and obtains the number of target sub - frames according to the quantitative relationship between the display switching offset of the mth field and the preset unit duration.

[0097] Before the start of the (m + 2)-th field display, calculate the display switching offset of the m-th field based on the field synchronization flag of the (m + 2)-th field in the control terminal field synchronization signal and the display end moment of the (m + 1)-th field in the corresponding enable signal of the driving circuit, that is, the time difference between the field synchronization flag of the (m + 2)-th field and the display end moment of the (m + 1)-th field; thus, if the display switching offset of the m-th field is positive and not greater than the upper limit value of the preset threshold range, then before the start of the (m + 2)-th field display, the control terminal sends to the driving circuit that the single-scan display duration of the target sub-frame is A''' = A'', and the number of target sub-frames is zero, and there is no need to select the target sub-frame and adjust the single-scan display duration of the target sub-frame; if it is greater than the upper limit value of the threshold range, then before the start of the (m + 2)-th field display, the control terminal sends to the driving circuit that the single-scan display duration of the target sub-frame is A''' = A'' + 1 preset unit duration, and obtains the number of target sub-frames according to the quantitative relationship between the display switching offset of the m-th field and the unit duration.
