[0046] In the related art, as shown in Figure 1, the video stream received by the timing controller includes multiple initial display frames (F1, F2, F3), each of which includes a light-emitting phase S1 and a blanking phase S2. In order to achieve frequency conversion, the duration of the blanking phase S2 in each initial display frame is continuously lengthened from the initial display frame F1 to the initial display frame F3, so that the frame rate is continuously reduced. Then, the brightness control signal generated by the timing controller based on the video stream is a pulse signal, which includes multiple pulses P. The duty cycle of the portion of the brightness control signal corresponding to each initial display frame changes, which can easily lead to flicker.

[0047] Figure 2 is a schematic block diagram of a display device. Figure 3 is a schematic diagram of a video stream. Figure 4 is a schematic diagram of correcting a display frame and brightness control signal. The present disclosure provides a control method for a timing controller 2. The timing controller 2 is used in a display device. The display device may further include a processor 1 and a display panel 3. The control method may include:

[0048] Step S10, receiving and storing a video stream, which includes n initial display frames (F1, F2, F3...Fn) arranged in sequence, where n is greater than or equal to 2, and the frame rate of the initial display frames increases or decreases from the first initial display frame F1 to the nth initial display frame Fn.

[0049] Step S20: Generate a brightness control signal and n modified display frames (XF1, XF2, XF3 . . . XFn) based on the n initial display frames, where the n modified display frames correspond to the n initial display frames. The brightness control signal is a pulse signal and includes n control segments K, where the n control segments K correspond to the n modified display frames.

[0050] Step S30 : sending the brightness control signal and the n modified display frames to the display panel 3 , so that the display panel 3 performs display according to the modified display frames.

[0051] The control method of the embodiment of the present disclosure generates a brightness control signal and n corrected display frames based on n initial display frames, and the n corrected display frames correspond to the n initial display frames. The brightness control signal and the n corrected display frames are sent to the display panel 3 so that the display panel 3 displays according to the corrected display frames, avoiding the display panel 3 displaying according to the initial display frames, thereby improving the display effect.

[0052] The following describes in detail the steps of the control method according to the embodiment of the present disclosure:

[0053] In step S10, a video stream is received and stored, wherein the video stream includes n initial display frames (F1, F2, F3...Fn) arranged in sequence, where n is greater than or equal to 2, and the frame rate of the initial display frames increases or decreases from the first initial display frame to the nth initial display frame.

[0054] The video stream can be generated by the processor 1. Specifically, the above-mentioned display device may further include a memory. A plurality of software applications may be stored in the memory. The software application may represent a video game, a virtual reality (VR) or an augmented reality (AR) application. As part of the execution process. The processor 1 executes the software application to generate a video stream. The processor 1 may send a video stream to the timing controller 2 via a display interface based on the eDP embedded display port standard, and the timing controller 2 may receive the video stream from the processor 1 via the display interface and store it.

[0055] The video stream includes n initial display frames arranged in sequence, where n is greater than or equal to 2. Each initial display frame may include a light-emitting phase S1 and a blanking phase S2. The blanking phase S2 may be a vertical blanking (V-blanking) phase. The duration of the light-emitting phase S1 of the n initial display frames may be the same.

[0056] The video streams in Figures 1 and 3 are the same. In one embodiment, as shown in Figures 1 and 3, from the first initial display frame F1 to the nth initial display frame Fn, the frame rate of the initial display frame decreases successively, and the time of the blanking phase S2 of the initial display frame increases successively. Specifically, in Figures 1 and 3, the frame rate of the first initial display frame F1 is 144Hz, the frame rate of the second initial display frame F2 is 143Hz, the frame rate of the third initial display frame F3 is 142Hz, and the frame rate of the nth initial display frame Fn is 115.2Hz. The frame rate mentioned in the present disclosure is the refresh rate. From the first initial display frame F1 to the nth initial display frame Fn, the light-emitting phase S1 of each initial display frame corresponds to 2000H (pixel row). The blanking period S2 of the first initial display frame F1 corresponds to 208H, the blanking period S2 of the second initial display frame F2 corresponds to 223H (width W1 corresponds to 15H), the blanking period S2 of the third initial display frame F3 corresponds to 239H (width W2 corresponds to 31H), and the blanking period S2 of the nth initial display frame Fn corresponds to 760H. In FIG1 , the brightness control signal includes multiple repeating units K1, each repeating unit K1 corresponding to 552H. Each repeating unit K1 includes a pulse P and an interval Q. In another embodiment, the frame frequency of the initial display frames increases from the first initial display frame F1 to the nth initial display frame Fn, and the duration of the blanking period S2 of the initial display frame decreases.

[0057] In step S20, a brightness control signal and n modified display frames (XF1, XF2, XF3 ... XFn) are generated based on the n initial display frames. The n modified display frames (XF1, XF2, XF3 ... XFn) correspond to the n initial display frames (F1, F2, F3 ... Fn). The brightness control signal is a pulse signal and includes n control segments K. The n control segments K correspond to the n modified display frames (XF1, XF2, XF3 ... XFn).

[0058] Taking the example of the frame rate of the initial display frames decreasing sequentially from the first initial display frame F1 to the nth initial display frame Fn, the frame rate of the modified display frames from the second modified display frame XF2 to the nth modified display frame XFn remains the same, and the frame rate of the first modified display frame XF1 is greater than the frame rate of the second modified display frame XF2. Specifically, in Figure 4, the frame rate of the first modified display frame XF1 is 144 Hz, while the frame rates of the second modified display frame XF2 through the nth modified display frame XFn are all 115.2 Hz. From the first modified display frame XF1 to the nth modified display frame XFn, the light-emitting phase S1 of each modified display frame corresponds to 2000 Hz (pixel row). The blanking phase S2 of the first modified display frame XF1 corresponds to 208 Hz, while the blanking phase S2 of the second modified display frame XF2 through the nth modified display frame XFn all correspond to 760 Hz.

[0059] In Figure 4 , the brightness control signal includes n control segments K. Each control segment K may include multiple repeating units K1, with each repeating unit K1 corresponding to management 552H. Each repeating unit K1 includes a pulse P and an interval Q. The duty cycle of the n control segments K can be the same. This duty cycle is equal to the ratio of the sum of the widths of all pulses P in a control segment K to the duration of the entire control segment K. The width of a pulse P refers to the duration of a single pulse P. The number of pulses P in each of the n control segments K can be an integer, such as 4, 5, or 6. At least two of the n control segments K have the same number of pulses P.

[0060] In one embodiment, the number of pulses P of the (n-1) control segments K corresponding to the second modified display frame XF2 to the nth modified display frame XFn is the same; optionally, the number of pulses P of the control segments K corresponding to the first modified display frame XF1 and the second modified display frame XF2 is different. From the first initial display frame F1 to the nth initial display frame Fn, taking the frame frequency of the initial display frames decreasing successively as an example, the number of pulses P in the control segment K corresponding to the first corrected display frame XF1 is less than the number of pulses P in the control segment K corresponding to the second corrected display frame XF2. For example, the number of pulses P in the control segment K corresponding to the first corrected display frame XF1 is 4, and the number of pulses P in the control segment K corresponding to the second corrected display frame XF2 is 5; from the first initial display frame F1 to the nth initial display frame Fn, taking the frame frequency of the initial display frames increasing successively as an example, the number of pulses P in the control segment K corresponding to the first corrected display frame XF1 is greater than the number of pulses P in the control segment K corresponding to the second corrected display frame XF2.

[0061] In another embodiment, the frame frequency of the initial display frames decreases from the first initial display frame F1 to the nth initial display frame Fn, the number of pulses P in the control segment K corresponding to the mth modified display frame is equal to the number of pulses P in the control segment K corresponding to the first modified display frame XF1, and m is greater than or equal to 3; the widths of the multiple pulses P in the control segment K corresponding to the mth modified display frame are equal, the width of the pulse P in the control segment K corresponding to the mth modified display frame is greater than the width of the pulse P in the control segment K corresponding to the first modified display frame XF1, and the difference between the widths of the two pulses P is a first difference C0, and the product of the first difference C0 and the number B0 of pulses P in the control segment K corresponding to the first modified display frame XF1 is equal to the difference E0 between the blanking periods S2 in the (m-1)th initial display frame and the first initial display frame F1, that is, C0*B0=E0, where "*" represents a multiplication operation. Specifically, in FIG5 , the widths of the plurality of pulses P in a single control segment K are equal; the width W5 of the pulse P in the control segment K corresponding to the first correction display frame XF1 is equal to the width W6 of the pulse P in the control segment K corresponding to the second correction display frame XF2, that is, in FIG5 , W5=W6; the width W7 of the pulse P in the control segment K corresponding to the third correction display frame XF3 is greater than the width W6 of the pulse P in the control segment K corresponding to the second correction display frame XF2, and the product of the difference between the two pulse P widths and the number of pulses P can be equal to the width W1 in FIG1 , that is, in FIG5 . 5, W7>W6, and (W7-W6)*number of pulses P=W1; the pulse P width W8 in the control segment K corresponding to the fourth corrected display frame XF4 is greater than the pulse P width W7 in the control segment K corresponding to the third corrected display frame XF3, and the product of the difference between the two pulse P widths and the number of pulses P can be equal to the width W2 in FIG1, that is, in FIG5, W8>W7, and (W8-W7)*number of pulses P=W2; it can be seen that in this embodiment, the present disclosure distributes the excess portion of the brightness control signal due to the change in frame rate evenly to each pulse P in the next control segment K.

[0062] In another embodiment, the frame frequency of the initial display frames decreases successively from the 1st initial display frame F1 to the nth initial display frame Fn, the number of pulses P in the control segment K corresponding to the mth modified display frame is equal to the number of pulses P in the control segment K corresponding to the 1st modified display frame XF1, and m is greater than or equal to 3; among the multiple pulses P in the control segment K corresponding to the mth modified display frame, the width of the last pulse P is greater than the width of any other pulse P, and the difference between the width of the last pulse P and the width of any other pulse P is a second difference; the second difference is equal to the difference between the blanking stages S2 in the (m-1)th initial display frame and the 1st initial display frame F1. Specifically, in FIG6 , the widths of the pulses P in the control segment K corresponding to the first correction display frame XF1 are equal, the widths of the pulses P in the control segment K corresponding to the second correction display frame XF2 are equal, the width of the pulses P in the control segment K corresponding to the first correction display frame XF1 is equal to the width of the pulses P in the control segment K corresponding to the second correction display frame XF2; in the control segment K corresponding to the third correction display frame XF3, except for the last pulse P, the widths of the remaining pulses P are equal to the width of the pulses P in the control segment K corresponding to the second correction display frame XF2; in the control segment K corresponding to the third correction display frame XF3, The width W3 of the last pulse P is greater than the widths of the remaining pulses P, and the difference between them can be equal to the width W1 in Figure 1; in the control segment K corresponding to the 4th corrected display frame XF4, except for the last pulse P, the widths of the remaining pulses P are equal to the widths of the pulses P in the control segment K corresponding to the 2nd corrected display frame XF2; in the control segment K corresponding to the 4th corrected display frame XF4, the width W4 of the last pulse P is greater than the widths of the remaining pulses P, and the difference between them can be equal to the width W2 in Figure 1; it can be seen that in this embodiment, the present disclosure allocates the extra part of the brightness control signal due to the change in frame frequency to the last pulse P of the next control segment K.

[0063] In step S30 , the brightness control signal and the n modified display frames are sent to the display panel 3 , so that the display panel 3 performs display according to the modified display frames.

[0064] The display panel 3 of the embodiment of the present disclosure may include a driver chip 301 (Source IC), a pixel circuit 303, and a gate driver circuit 302. The pixel circuit 303 may be located within the display area and is used to drive the light-emitting elements of the display panel 3 to display. The gate driver circuit 302 may be connected to the pixel circuit 303 to send scan signals and brightness control signals to the pixel circuit 303. Both the pixel circuit 303 and the gate driver circuit 302 are connected to the driver chip 301. The timing controller 2 is used to send the brightness control signal and n corrected display frames to the driver chip 301. The driver chip 301 sends a control signal to the gate driver circuit 302 based on the brightness control signal, so that the gate driver circuit 302 sends the scan signal and brightness control signal to the pixel circuit 303. The driver chip 301 is used to send n corrected display frames to the pixel circuit 303. The display panel 3 is used to display according to the corrected display frames. The luminance of the display panel 3 can be controlled by the duty cycle of the control segment K corresponding to the corrected display frame. When the duty cycles are the same, the brightness can be the same. Since the duty cycles of the n control sections K can be the same, the light emitting brightness of the display panel 3 can be the same, thus avoiding flickering.

[0065] The embodiment of the present disclosure may further provide a timing controller 2. The timing controller 2 may include a storage module 201, a generation module 202, and a sending module 203, wherein:

[0066] The storage module 201 is configured to receive and store a video stream, wherein the video stream includes n initial display frames arranged in sequence, where n is greater than or equal to 2, and the frame rate of the initial display frames increases or decreases from the first initial display frame to the nth initial display frame. The storage module 201 is configured to execute the above-mentioned step S10.

[0067] The generation module 202 generates a brightness control signal and n modified display frames based on n initial display frames, where the n modified display frames correspond to the n initial display frames. The brightness control signal is a pulse P signal and includes n control segments K, where the n control segments K correspond to the n modified display frames. The generation module 202 is configured to execute step S20 described above.

[0068] The sending module 203 sends the brightness control signal and the n modified display frames to the display panel 3, so that the display panel 3 performs display according to the modified display frames. The sending module 203 is used to perform the above step S30.

[0069] The present disclosure also provides a display device, which may include the processor 1 , the display panel 3 , and the timing controller 2 of any one of the above embodiments.

[0070] The display device, timing controller and control method thereof provided in the embodiments of the present disclosure belong to the same inventive concept, and the description of relevant details and beneficial effects can be referred to each other and will not be repeated here.

[0071] The above is merely a preferred embodiment of the present disclosure and does not constitute any form of limitation to the present disclosure. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not intended to limit the present disclosure. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the technical content disclosed above without departing from the scope of the technical solution of the present disclosure.
