Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are shown in the drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element and be integral therewith, or intervening elements may also be present. The terms "mounted," "one end," "the other end," and the like are used herein for illustrative purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
In order to solve the problem of display non-uniformity of the conventional display panel, in one embodiment, as shown in fig. 1, there is provided a display panel driving method including the steps of:
step S110, when the display panel is detected to finish the current display, respectively writing reset voltage into each reset line corresponding to the scanning drive circuit in the drive circuit so as to reset the source electrode of the drive TFT in the drive circuit; the reset voltage is correspondingly reduced as the distance between the reset line and the corresponding scan driving circuit increases.
It should be noted that after each display of the display panel is completed, the source of the driving TFT in the driving circuit of the display panel needs to be reset, so as to ensure the display quality of each display. An Integrated Circuit (IC) circuit of the drive circuit writes a corresponding reset voltage (V) into a reset line (pre line) of the drive circuit after detecting that the current display of the display panel is completedpre)。
In an example, as shown in fig. 2, the scan driving circuit 21 is disposed on only one side of the driving circuit 23, the reset voltage corresponding to writing is set according to the distance from the reset line 25 (the reset line 25 is connected to the data driving circuit 27) to the corresponding scan driving circuit 21, and the reset line 25 farther from the corresponding scan driving circuit 21 is less affected by feed through (feedthru) caused by the gate turn-off of the driving TFT, and the reset voltage corresponding to writing is relatively smaller. The value of the reset voltage is related to the Gate resistance capacitance (Gate RC, in a pixel circuit, a voltage signal is transmitted to different positions of a panel and needs to pass through capacitances and resistance circuits with different sizes, the larger the capacitance resistance is, the more obvious the hysteresis effect of signal transmission is, the on-off time of a drive TFT switch can be increased, the speed of reducing the voltage from high voltage to low voltage during the off process is slowed down), the requirement of not allowing an OLED device to be turned on is met, and particularly, the size of the reset voltage written in by different reset lines can be determined through a simulation technology. In one example, the reset voltage ranges from 1 volt to 1.5 volts, for example, the reset line nearest to the corresponding scan driving circuit writes a reset voltage of 1.5 volts, and the reset line farthest from the corresponding scan driving circuit writes a reset voltage of 1 volt. The feed-through phenomenon refers to the fact that parasitic capacitance exists between a gate metal and a source metal of a driving TFT, and at the moment of switching, the gate voltage is rapidly reduced from a high potential to a low potential, and the gate voltage changes according to the charge conservation principle.
In another example, the scan driving circuits are disposed on two opposite sides of the driving circuit, the scan driving circuits on the two sides respectively affect the reset lines on the driving circuit, and the scan driving circuits on the two sides have greater effect on the reset lines closer to each other, so that the reset lines on the driving circuit are divided into two parts according to the distance from the scan driving circuits, one part is mainly affected by the scan driving circuit on one side, and the other part is mainly affected by the scan driving circuit on the other side. Specifically, as shown in fig. 3, the scan driving circuit 21 includes a first side scan driving circuit 211 and a second side scan driving circuit 213; the first side scanning drive circuit 211 and the second side scanning drive circuit 213 are provided at opposite both side ends on the drive circuit 23; the reset line 25, which has a distance to the first side scan driving circuit 211 smaller than that to the second side scan driving circuit 213, corresponds to the first side scan driving circuit 211; the reset lines 25 whose distance to the first side scan driving circuit 211 is greater than or equal to the distance to the second side scan driving circuit 213 correspond to the second side scan driving circuit 213, that is, all the reset lines 25 between the two side scan driving circuits are divided into half, the reset lines whose distance to the first side scan driving circuit 211 is less than the distance to the second side scan driving circuit 213 refer to the first side scan driving circuit 211 when writing the reset voltage; the reset line 25, which is located at a distance greater than or equal to the distance from the first side scan driving circuit 211 to the second side scan driving circuit 213, refers to the second side scan driving circuit 213 when writing the reset voltage.
The reset line of the scanning driving circuit relative to the first side is correspondingly reduced along with the increase of the distance of the reset line relative to the scanning driving circuit of the first side; the reset line of the second side scanning driving circuit is correspondingly reduced along with the distance of the reset line of the second side scanning driving circuit relative to the second side scanning driving circuit.
The display panel driving method of the present application can be applied to, but is not limited to: a 3T1C type pixel drive circuit, a 4T2C type pixel drive circuit, a 5T2C type pixel drive circuit, or a 6T1C type pixel drive circuit. The following description will be made by taking a 3T1C type pixel driving circuit (as shown in fig. 4) as an example: the 3T1C type pixel driving circuit includes a scan TFT (i.e., Gate TFT in FIG. 4), a Drive TFT (i.e., Drive TFT in FIG. 4), a sense TFT (i.e., Sen TFT in FIG. 4), and a capacitor (i.e., C in FIG. 4)gs) (ii) a The grid electrode of the scanning TFT is connected with a scanning line (namely Scan in figure 4), the drain electrode is connected with a Data line (namely Data in figure 4), and the source electrode is respectively connected with the grid electrode of the driving TFT and one end of the capacitor; the drain electrode of the driving TFT is externally connected with a voltage source (namely VDD in figure 4), and the source electrode of the driving TFT is respectively connected with the other end of the capacitor, the source electrode of the sensing TFT and the OLED device; the gate of the sensing TFT is connected to the control line (i.e., Sense in fig. 4), the drain is connected to the reset line (i.e., Pre in fig. 4), and the source is connected to the other end of the capacitor, the source of the sensing TFT, and the OLED device, respectively.
In the embodiment of the display panel driving method, when it is detected that the display panel finishes displaying at the current time, the reset voltage is written into each reset line corresponding to the scanning driving circuit in the driving circuit respectively, so as to reset the source electrode of the driving TFT in the driving circuit, wherein the reset voltage is correspondingly reduced along with the increase of the distance between the reset line and the corresponding scanning driving circuit, the corresponding reset voltage is written into the reset lines which are far away from the scanning driving circuit respectively, and the reset voltage is correspondingly reduced along with the increase of the distance, thereby changing the mode of inputting the same reset voltage to the whole driving circuit in the traditional technology, realizing the reduction of the influence of feed-through caused by the closing of the gate of the driving TFT due to the increase of the distance between the reset line and the scanning driving circuit, reducing the written reset voltage, and further enabling the source electrode voltages of the driving TFTs at different positions on the driving circuit to be consistent, thereby improving the display uniformity of the panel.
In one embodiment, in order to avoid the situation of large reset workload and low efficiency caused by setting different reset voltages for each reset line, the area occupied by each reset line corresponding to the scanning driving circuit is sequentially divided into a first area, a second area and a third area along the direction far away from the scanning driving circuit. Each reset line corresponding to the scan driving circuit is a reset line mainly affected by the scan driving circuit.
In one example, when the scan driving circuit is provided only on one side of the driving circuit, the entire driving circuit is sequentially divided into a first region, a second region, and a third region in a direction away from the scan driving circuit.
In another example, the scan driving circuits are disposed on two opposite sides of the driving circuit, the entire driving circuit is first symmetrically divided into a first portion (the scan driving circuit on the opposite side of the first portion) and a second portion (the scan driving circuit on the opposite side of the second portion) along the central axis (the central axis is parallel to the side end where the scan driving circuit is disposed), the entire first portion is sequentially divided into a first region, a second region, and a third region along the direction away from the scan driving circuit on one side, and the entire second portion is sequentially divided into a first region, a second region, and a third region along the direction away from the scan driving circuit on the other side.
In one example, the first region, the second region, and the third region are different in region size from each other. In another example, the regions of the first region, the second region, and the third region are equal in size.
Writing different reset voltages into different areas respectively, specifically, inputting a first reset voltage into each reset circuit in a first area; inputting a second reset voltage to each reset line in the second region; inputting a third reset voltage to each reset line in the third region; the first reset voltage is greater than the second reset voltage; the second reset voltage is greater than the third reset voltage. Further, in one example, the first reset voltage has a value ranging from 1 volt to 1.5 volts; the value range of the second reset voltage is 1 volt to 1.5 volts; the third reset voltage has a value in the range of 1 volt to 1.5 volts.
This embodiment gives a way of dividing into three regions, but does not exclude other region division ways, e.g. 4 regions, 5 regions, 6 regions, etc.
In the embodiment of the display panel driving method, the corresponding reset voltage is written according to the regions, the corresponding reset voltage is prevented from being set for each reset circuit, the number of the reset voltages is only required to be set according to the number of the divided regions, the reset workload is reduced, the reset efficiency is improved, the source electrode voltages of the driving TFTs at different positions on the driving circuit are consistent, and the display uniformity of the panel is improved.
In one embodiment, as shown in fig. 5, there is also provided a display driving circuit including a driving circuit 51 and an IC circuit 53;
the IC circuit 53 is configured to, when it is detected that the display panel completes the current display, write a reset voltage to each reset line corresponding to the scan driving circuit in the driving circuit 51, respectively, so as to reset the source of the driving TFT in the driving circuit 61; the reset voltage is correspondingly reduced as the distance between the reset line and the corresponding scan driving circuit increases.
The IC circuit is a control center of the driver circuit and is also a supplier of the reset voltage. And after detecting that the current display of the display panel is finished, the IC circuit writes corresponding reset voltages into reset lines in the driving circuit respectively. In one example, the scan driving circuit is disposed on only one side of the driving circuit, and the IC circuit reduces the written reset voltage according to the increase of the distance from the reset line to the corresponding scan driving circuit, specifically, the reset voltage has a value ranging from 1 v to 1.5 v.
In another example, the scan driving circuits are disposed on opposite sides of the driving circuit, the scan driving circuit including a first side scan driving circuit and a second side scan driving circuit; the first side scanning driving circuit and the second side scanning driving circuit are arranged at two opposite side ends of the driving circuit; the reset circuit with the distance to the first side scanning driving circuit smaller than that to the first side scanning driving circuit corresponds to the first side scanning driving circuit; the reset line having a distance from the first side scan driving circuit greater than or equal to that from the first side scan driving circuit corresponds to the second side scan driving circuit. The reset voltage written by the IC circuit to the reset circuit opposite to the first side scanning driving circuit is correspondingly reduced along with the increase of the distance of the reset circuit relative to the first side scanning driving circuit; the reset voltage written by the IC circuit to the reset line of the opposite second side scanning driving circuit is correspondingly reduced along with the increase of the distance of the reset line relative to the second side scanning driving circuit.
In one embodiment, in order to avoid the situation of large reset workload and low efficiency caused by setting different reset voltages for each reset line, an area occupied by each reset line corresponding to the scan driving circuit is sequentially divided into a first area, a second area and a third area along a direction far away from the scan driving circuit, and correspondingly, the IC circuit includes: the first output unit is used for inputting a first reset voltage to each reset line in the first area; the second output unit is used for inputting a second reset voltage to each reset line in the second area; the third output unit is used for inputting a third reset voltage to each reset line in the third area; the first reset voltage is greater than the second reset voltage; the second reset voltage is greater than the third reset voltage.
Further, in one example, the first reset voltage has a value ranging from 1 volt to 1.5 volts; the value range of the second reset voltage is 1 volt to 1.5 volts; the third reset voltage has a value in the range of 1 volt to 1.5 volts.
This embodiment gives a way of dividing into three regions, but does not exclude other region division ways, e.g. 4 regions, 5 regions, 6 regions, etc.
