具体实施方式detailed description
本发明实施例提供的一种显示面板的显示控制电路、显示装置及显示装置的显示控制方法，在同一行像素单元连接的栅极线被选通时，可以通过控制各个可控开关单元，使得该行像素单元都不会同时接收数据传输单元传输的数据，从而使得同一行的像素单元不会同时点亮，进而提高显示面板上的画面的刷新率。The display control circuit, the display device, and the display control method of the display device provided by the embodiment of the present invention can control each of the controllable switch units when the gate lines connected to the pixel units in the same row are gated. The pixel units of the row do not simultaneously receive the data transmitted by the data transmission unit, so that the pixel units of the same row are not lit at the same time, thereby improving the refresh rate of the screen on the display panel.
下面结合说明书附图，对本发明实施例提供的一种显示面板的显示控制电路、显示装置及显示装置的显示控制方法的具体实施方式进行说明。A specific embodiment of a display control circuit, a display device, and a display control method for a display device according to an embodiment of the present invention will be described below with reference to the accompanying drawings.
根据一种显示方式，当OLED显示面板需要显示图1所示的画面时，其显示顺序如图2所示，首先使显示面板中的第一行像素单元同时点亮；然后显示面板中的第二行像素单元同时点亮，此时，显示面板中的第一行像素单元仍维持点亮状态；然后显示面板中的第三行像素单元同时点亮，此时，显示面板中的第一行像素单元和第二行像素单元仍维持点亮。According to a display manner, when the OLED display panel needs to display the screen shown in FIG. 1, the display sequence thereof is as shown in FIG. 2, firstly, the first row of pixel units in the display panel are simultaneously illuminated; then the display panel The two rows of pixel units are simultaneously illuminated. At this time, the first row of pixel units in the display panel remains lit; then the third row of pixel units in the display panel are simultaneously illuminated. At this time, the first row in the display panel The pixel unit and the second row of pixel units remain lit.
如果OLED显示面板的帧频率为24Hz，即1秒中显示24帧，那么如果OLED显示面板中共有m行像素单元，那么，该OLED显示面板上的画面每秒钟刷新24*m次，由于显示面板上的画面每秒钟刷新次数越多，图像就越稳定，图像显示就越自然清晰，对眼睛的影响也越小。而显示面板上的画面每秒钟刷新次数越少，图像闪烁和抖动的就越厉害，眼睛疲劳得就越快。因此，图2所示的显示方式由于显示面板上的画面每秒钟的刷新次数较少、即刷新率较低，很容易导致视觉疲劳。If the frame frequency of the OLED display panel is 24 Hz, that is, 24 frames are displayed in 1 second, if there are a total of m rows of pixel units in the OLED display panel, then the picture on the OLED display panel is refreshed 24*m times per second due to the display. The more the number of refreshes per second on the panel, the more stable the image will be, the more natural the image will be, and the less impact it will have on the eye. The less the number of refreshes per second on the display panel, the more the image flickers and shakes, and the faster the eyes are fatigued. Therefore, the display mode shown in FIG. 2 is likely to cause visual fatigue due to the fact that the number of refreshes per second on the display panel is small, that is, the refresh rate is low.
因此，采用这种有机发光二极管的显示面板的显示方式时，由于刷新率较低，很容易导致视觉疲劳。 Therefore, when the display mode of the display panel using such an organic light emitting diode is low, visual fatigue is easily caused due to a low refresh rate.

下面仅以每条数据线均通过可控开关单元连接数据传输单元为例进行说明，显示面板中存在直接连接数据传输单元的数据线时的显示面板的结构与每条数据线均通过可控开关单元连接数据传输单元时的显示面板的结构类似，在此不再赘述。The following is an example in which each data line is connected to the data transmission unit through a controllable switch unit.

可选地，如图4所示，每个可控开关单元包括一个薄膜晶体管(TFT，Thin Film Transistor)；每个TFT T的源极连接数据传输单元34，该TFT T的漏极连接包括该TFT T的可控开关单元所连接的数据线33，该TFT T的栅极连接控制单元36。图4是以每条数据线33均通过可控开关单元35连接数据传输单元34为例进行说明的。Optionally, as shown in FIG. 4, each of the controllable switch units includes a thin film transistor (TFT); the source of each TFT T is connected to the data transfer unit 34, and the drain connection of the TFT T includes the A data line 33 to which the controllable switching unit of the TFT T is connected, and a gate of the TFT T is connected to the control unit 36. 4 is an example in which each of the data lines 33 is connected to the data transfer unit 34 via the controllable switch unit 35 as an example.
每个可控开关单元中的TFT可以为p型TFT，也可以为n型TFT，图4中以n型TFT为例进行说明。The TFT in each of the controllable switching units may be a p-type TFT or an n-type TFT, and an n-type TFT is taken as an example in FIG.
当然，每个可控开关单元还可以包括多个TFT，这多个TFT的栅极连接在一起，并连接控制单元，多个TFT串联/并联在一起。Of course, each of the controllable switching units may further include a plurality of TFTs, the gates of the plurality of TFTs being connected together and connected to the control unit, and the plurality of TFTs being connected in series/parallel.

Gate line 52;
扫描单元51，用于控制各条栅极线52按照设定的顺序选通，以使得与 该条栅极线52相连的像素单元能够接收数据传输单元34输出的数据。The scanning unit 51 is configured to control each of the gate lines 52 to be gated in a set order so that The pixel unit connected to the gate line 52 is capable of receiving data output from the data transfer unit 34.
若可控开关单元包括TFT，则本发明实施例提供的显示装置如图5b所示。If the controllable switch unit includes a TFT, the display device provided by the embodiment of the present invention is as shown in FIG. 5b.
其中，本发明实施例提供的显示装置中的像素单元可以采用图6所示的结构。在图6中，第一晶体管T1的栅极接收扫描信号Scan，第一晶体管T1的源极接收数据信号Data，第一晶体管T1的漏极连接第二晶体管T2的栅极，第二晶体管T2的源极和第三晶体管T3的源极均接收高电平信号Vdd，第三晶体管T3的栅极连接第二晶体管T2的漏极，第三晶体管T3的漏极连接有机发光二极管OLED的阳极，有机发光二极管OLED的阴极接地，第一电容C1的一端连接第三晶体管T3的栅极，第一电容C1的另一端接地，第四晶体管T4的源极连接第三晶体管T3的栅极，第四晶体管T4的栅极接收复位信号Reset，第四晶体管T4的漏极接地。The pixel unit in the display device provided by the embodiment of the present invention may adopt the structure shown in FIG. 6. In FIG. 6, the gate of the first transistor T1 receives the scan signal Scan, the source of the first transistor T1 receives the data signal Data, the drain of the first transistor T1 is connected to the gate of the second transistor T2, and the second transistor T2 The source and the source of the third transistor T3 each receive a high level signal Vdd, the gate of the third transistor T3 is connected to the drain of the second transistor T2, and the drain of the third transistor T3 is connected to the anode of the organic light emitting diode OLED, organic The cathode of the light emitting diode OLED is grounded, one end of the first capacitor C1 is connected to the gate of the third transistor T3, the other end of the first capacitor C1 is grounded, the source of the fourth transistor T4 is connected to the gate of the third transistor T3, and the fourth transistor The gate of T4 receives the reset signal Reset, and the drain of the fourth transistor T4 is grounded.
其中，第一晶体管T1的栅极接收到的扫描信号Scan与该像素单元连接的栅极线上的信号相同，因此，当该像素单元连接的栅极线被选通时，第一晶体管T1导通，第一晶体管T1的源极接收到的数据信号Data传输到第二晶体管T2的栅极，数据信号Data是该像素单元连接的数据线上的信号；第二晶体管T2是一个源极跟随器，即电压跟随器，第二晶体管T2的主要作用是功率放大；第四晶体管T4的栅极接收到的复位信号Reset与该像素单元连接的栅极线的前一条栅极线上的信号相同，这样在第k帧画面内，需要给第l行数据充电，而第l+1行此时依然是k-1帧数据，通过复位信号reset控制第四晶体管T4导通，从而给第l+1行的像素单元中的电容放电，使得有机发光二极管OLED显示正常。The scan signal Scan received by the gate of the first transistor T1 is the same as the signal on the gate line connected to the pixel unit. Therefore, when the gate line connected to the pixel unit is gated, the first transistor T1 leads. The data signal Data received by the source of the first transistor T1 is transmitted to the gate of the second transistor T2, the data signal Data is the signal on the data line connected to the pixel unit, and the second transistor T2 is a source follower. The voltage follower, the main function of the second transistor T2 is power amplification; the reset signal Reset received by the gate of the fourth transistor T4 is the same as the signal on the previous gate line of the gate line connected to the pixel unit, Thus, in the kth frame picture, the data of the 1st line needs to be charged, and the l+1th line is still k-1 frame data at this time, and the fourth transistor T4 is controlled to be turned on by the reset signal reset, thereby giving the l+1th. The capacitance in the pixel unit of the row is discharged, so that the organic light emitting diode OLED is displayed normally.
当然，本发明实施例提供的显示装置中的像素单元也可以采用其他的结构。Of course, the pixel unit in the display device provided by the embodiment of the present invention may also adopt other structures.
图5a和图5b中仅给出了每条数据线均通过可控开关单元连接数据传输单元时的显示装置的结构，当然，本发明实施例提供的显示装置中也可以存在直接连接数据传输单元的数据线的情况。FIG. 5a and FIG. 5b show only the structure of the display device when each data line is connected to the data transmission unit through the controllable switch unit. Of course, the display device provided by the embodiment of the present invention may also have a direct connection data transmission unit. The case of the data line.
本发明实施例提供的显示装置的显示控制方法，如图7所示，包括：The display control method of the display device provided by the embodiment of the present invention, as shown in FIG. 7, includes:
S701、针对显示装置中的显示面板上的各条栅极线中的一条栅极线，确定该条栅极线被选通；S701. Determine, according to one of each of the gate lines on the display panel in the display device, the gate line is gated;
S702、若该显示装置中存在直接连接数据传输单元的数据线，则在该条栅极线被选通的时间段内，控制至少一个可控开关单元在预设时刻开始导通， 预设时刻为从该条栅极线被选通的起始时刻起经过预设时长后的时刻；S702. If there is a data line directly connected to the data transmission unit in the display device, control at least one controllable switch unit to start conducting at a preset time during a period in which the gate line is gated. The preset time is a time after a preset time period elapses from a start time at which the gate line is gated;
S703、若该显示装置中不存在直接连接数据传输单元的数据线，即显示装置中的各条数据线均通过可控开关单元连接数据传输单元，则在该条栅极线被选通的时间段内，控制各个可控开关单元不同时导通。S703. If there is no data line directly connected to the data transmission unit in the display device, that is, each data line in the display device is connected to the data transmission unit through the controllable switch unit, when the gate line is gated In the segment, each controllable switch unit is controlled to be turned on at the same time.
其中，S702和S703在执行时没有时间上的先后顺序，具体执行S702和S703中的哪一个要看显示装置的结构满足哪一种条件。S702 and S703 have no chronological order in execution, and which one of S702 and S703 is to be executed depends on which condition the structure of the display device satisfies.
当显示装置中仅有一条数据线通过可控开关单元连接数据传输单元时，那么显示装置的结构仅满足显示装置中存在直接连接数据传输单元的数据线的条件，因此，要执行S702。当显示装置中有两条以上的数据线通过可控开关单元连接数据传输单元、且显示装置中存在直接连接数据传输单元的数据线时，那么显示装置的结构不但满足显示装置中存在直接连接数据传输单元的数据线的条件，并且满足显示装置中有至少两条数据线通过可控开关单元连接数据传输单元的条件，因此，可以执行S702、也可以执行S703，还可以对一部分可控开关单元执行S702、对另一部分可控开关单元执行S703。When only one data line in the display device is connected to the data transfer unit through the controllable switch unit, the structure of the display device only satisfies the condition that the data line directly connected to the data transfer unit exists in the display device, and therefore, S702 is performed. When more than two data lines in the display device are connected to the data transmission unit through the controllable switch unit, and the data line directly connected to the data transmission unit exists in the display device, the structure of the display device not only satisfies the existence of direct connection data in the display device The condition of the data line of the transmission unit, and satisfies the condition that at least two data lines in the display device are connected to the data transmission unit through the controllable switch unit. Therefore, S702 can be performed, S703 can also be performed, and a part of the controllable switch unit can also be executed. Execution S702, performing S703 on another part of the controllable switch unit.
例如，当显示装置中仅有一条数据线通过可控开关单元连接数据传输单元时，若在(t1，t2)的时间段内，某一行像素单元连接的栅极线被选通，那么，可以控制该条数据线连接的可控开关单元在预设时刻t3开始导通，其中，t3>t1，t3<t2，预设时长为t3-t1。这样，显示面板上的画面的刷新率相比于采用现有的显示方式时的画面的刷新率提高了，这降低了视觉疲劳。For example, when only one data line in the display device is connected to the data transmission unit through the controllable switch unit, if the gate line connected to a row of pixel units is gated during the period of (t1, t2), then The controllable switch unit that controls the connection of the data line starts to conduct at a preset time t3, where t3>t1, t3<t2, and the preset duration is t3-t1. Thus, the refresh rate of the screen on the display panel is improved compared to the refresh rate of the screen when the existing display mode is used, which reduces visual fatigue.
例如，当显示装置中有至少两条数据线通过可控开关单元连接数据传输单元，且显示装置中存在直接连接数据传输单元的数据线时，若在(t1，t2)的时间段内，某一行像素单元连接的栅极线被选通，那么，可以控制显示装置中的各个可控开关单元均在预设时刻t3开始导通，其中，t3>t1，t3<t2，预设时长为t3-t1，也就是说，控制这些可控开关单元同时开始导通；也可以控制显示装置中的至少一个可控开关单元均在预设时刻t3开始导通，而控制显示装置中的其它可控开关单元在(t1，t2)的时间段内的其它时刻开始导通，也就是说，控制可控开关单元不同时导通。这两种控制方法都能够提高显示面板上的画面的刷新率，从而降低视觉疲劳。For example, when at least two data lines in the display device are connected to the data transmission unit through the controllable switch unit, and there is a data line directly connected to the data transmission unit in the display device, if during the time period of (t1, t2), The gate lines connected to one row of pixel units are gated, then each controllable switching unit in the display device can be controlled to be turned on at a preset time t3, where t3>t1, t3<t2, and the preset duration is t3. -t1, that is, controlling the controllable switch units to start conducting at the same time; or controlling at least one controllable switch unit in the display device to start conducting at a preset time t3, and controlling other controllable in the display device The switching unit starts to conduct at other times during the period of (t1, t2), that is, the controllable switching unit is not turned on at the same time. Both of these control methods can improve the refresh rate of the picture on the display panel, thereby reducing visual fatigue.
当显示装置中的每条数据线均通过可控开关单元连接数据传输单元，即显示装置中不存在直接连接数据传输单元的数据线时，那么显示装置的结构满足显示装置中有至少两条数据线通过可控开关单元连接数据传输单元的条 件，因此，要执行S703。When each data line in the display device is connected to the data transmission unit through the controllable switch unit, that is, there is no data line directly connected to the data transmission unit in the display device, the structure of the display device satisfies at least two data in the display device. The line is connected to the strip of the data transmission unit through the controllable switching unit Therefore, to execute S703.
例如，当显示装置中每条数据线均通过可控开关单元连接数据传输单元时，假设显示面板上有2n列像素单元，若在(t1，t2)的时间段内，某一行像素单元连接的栅极线被选通，控制单元可以控制该行中的第1到n个像素单元在(t1，(t1+t2)/2)的时间段内接收数据传输单元传输的数据，控制该行中的第n+1到2n个像素单元在((t1+t2)/2，t2)的时间段内接收数据传输单元传输的数据，从而使得该行中的第1到n个像素单元从t1时刻起开始点亮，使得该行中的第n+1到2n个像素单元从(t1+t2)/2时刻起开始点亮，这样，显示面板上的画面的刷新率相比于采用现有的显示方式时的画面的刷新率提高了一倍，这降低了视觉疲劳。For example, when each data line in the display device is connected to the data transmission unit through the controllable switch unit, it is assumed that there are 2n columns of pixel units on the display panel, and if a row of pixel units is connected during the period of (t1, t2) The gate line is gated, and the control unit can control the first to n pixel units in the row to receive data transmitted by the data transmission unit during the period of (t1, (t1+t2)/2), and control the row. The n+1th to 2nth pixel unit receives the data transmitted by the data transmission unit during the period of ((t1+t2)/2, t2), so that the 1st to nth pixel units in the row are from the time t1 Start lighting, so that the n+1th to 2nth pixel unit in the row starts to light up from the time of (t1+t2)/2, so that the refresh rate of the picture on the display panel is compared with the existing one. The refresh rate of the screen when the display mode is doubled, which reduces visual fatigue.
可选地，如图8所示，在该条栅极线被选通的时间段内，控制各个可控开关单元不同时导通具体包括：S801、在该条栅极线被选通的时间段内，按照设定的顺序依次控制各个可控开关单元导通。Optionally, as shown in FIG. 8 , during the period in which the gate lines are gated, controlling the respective controllable switch units to be turned on at different times specifically includes: S801, when the gate lines are gated In the segment, the controllable switching units are sequentially turned on in the set order.
例如，假设显示面板上有2n列像素单元，若在(t1，t2)的时间段内，某一行像素单元连接的栅极线被选通，控制单元可以控制该行中的第1个像素单元在(t1，t1+(t2-t1)/2n)的时间段内接收数据传输单元传输的数据，控制该行中的第p个像素单元在(t1+(p-1)(t2-t1)/2n，t1+p*(t2-t1)/2n)的时间段内接收数据传输单元传输的数据，其中，p大于或等于1，且小于或等于2n；从而使得该行中的第p个像素单元从t1+(p-1)(t2-t1)/2n时刻起开始点亮，这样，显示面板上的画面的刷新率是采用现有的显示方式时的画面的刷新率的2n倍，这降低了视觉疲劳。For example, if there are 2n columns of pixel units on the display panel, if the gate lines connected to a row of pixel cells are gated during the period of (t1, t2), the control unit can control the first pixel unit in the row. Receiving data transmitted by the data transmission unit during the period of (t1, t1+(t2-t1)/2n), controlling the pth pixel unit in the row at (t1+(p-1)(t2-t1)/2n Receiving data transmitted by the data transmission unit during a period of time t1+p*(t2-t1)/2n), wherein p is greater than or equal to 1, and less than or equal to 2n; thereby causing the pth pixel unit in the row Lights up from the time t1+(p-1)(t2-t1)/2n, so that the refresh rate of the screen on the display panel is 2n times the refresh rate of the screen when using the existing display mode, which reduces Visual fatigue.
假设显示面板中需要显示图9所示的画面，那么采用图8所示的显示显示控制方法时，其显示顺序如图10所示。Assuming that the screen shown in FIG. 9 needs to be displayed in the display panel, when the display display control method shown in FIG. 8 is employed, the display order is as shown in FIG.
若可控开关单元中包括p型TFT，本发明实施例显示装置中的显示面板上有n条数据线，则控制单元可以输出图11所示的信号，以控制TFT导通，其中P1为第一条数据线连接的TFT的栅极接收到的信号，P2为第二条数据线连接的TFT的栅极接收到的信号，P3为第三条数据线连接的TFT的栅极接收到的信号，Pn-1为第n-1条数据线连接的TFT的栅极接收到的信号，Pn为第n条数据线连接的TFT的栅极接收到的信号。If the p-type TFT is included in the controllable switch unit, the display panel in the display device of the embodiment of the present invention has n data lines, and the control unit can output the signal shown in FIG. 11 to control the conduction of the TFT, wherein P1 is the first a signal received by the gate of the TFT connected to one data line, P2 is a signal received by the gate of the TFT connected to the second data line, and P3 is a signal received by the gate of the TFT connected to the third data line. Pn-1 is a signal received by the gate of the TFT connected to the n-1th data line, and Pn is a signal received by the gate of the TFT connected to the nth data line.
可选地，本发明实施例提供的显示装置的显示控制方法，如图12所示，还包括： Optionally, the display control method of the display device provided by the embodiment of the present invention, as shown in FIG. 12, further includes:
S1201、确定该显示装置中的显示面板上的各条栅极线均未被选通；S1201: determining that each of the gate lines on the display panel in the display device is not gated;
S1202、控制各个可控开关单元关断。S1202, controlling each controllable switch unit to be turned off.
也就是说，在显示装置未开始显示时，控制各个可控开关单元关断，若可控开关单元中包括p型TFT，也就是向各个TFT的栅极输出高电平信号。That is to say, when the display device does not start displaying, each controllable switching unit is controlled to be turned off. If the controllable switching unit includes a p-type TFT, that is, a high-level signal is output to the gates of the respective TFTs.
