Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
According to the application, the display panel is tested and analyzed, so that the wiring structure of the clock line of the display panel is one of the major reasons for the occurrence of defects such as transverse stripes, black screens and the like; currently, when the clock lines of the display panel are routed, the clock lines are parallel or approximately parallel to the edges of the display panel and then connected to the GOA devices through a turn, and the GOA devices are arranged in rows along the side edges of the display panel, and a cross-line condition exists between different metal lines, as shown in fig. 1. When the display panel is started, potential difference exists in different metal layer circuits in the clock line through level signals for a long time, and breakdown easily occurs between the metal lines after local potential is accumulated to a certain degree, so that defects such as transverse lines, black screens and the like of the display panel are caused. For example, taking 8CK (8 clock, 8clock signal) as an example, by analyzing multiple sets of panels, the results are as follows:
TABLE 1 Cross grain and black screen failure analysis
In table 1, ID represents a panel number, resistance represents a resistance of a short circuit between two clock lines, a short circuit point represents a row where the short circuit occurs, and cause analysis represents analysis of a metal layer of a display panel by a conventional method such as a scanning electron microscope; DGS represents a short circuit formed by breakdown of a metal layer (clock line); the opposite signal indicates the waveform inversion of the driving signal (clock signal) input from the clock line. Further, referring to fig. 2, it can be seen from fig. 2 that in the driving waveform of 8CK, the waveforms of the driving signals of different lines are opposite, especially, the CK1 signal and CK5 signal, the CK2 signal and CK6 signal, the CK3 signal and CK7 signal, and the CK4 signal and CK8 signal, and the waveforms of the driving signals are completely opposite, i.e. inverted, so that the risk of breakdown is higher. Meanwhile, in table 1, it can also be seen that in the position where breakdown occurs, the case where the drive signals are completely opposite occupies nearly half of the ratio.
In view of this, an embodiment of the present application provides an array substrate, so as to improve a clock line wiring structure of a display panel in the prior art, thereby at least partially solving and optimizing defects such as cross grains and black screens of the display panel caused by the wiring structure. The implementation details and the beneficial effects of the GOA circuit structure of the present application are explained and illustrated in more detail below by means of specific embodiments.
Referring to fig. 3, in an embodiment of the application, an array substrate 100 is provided, where the array substrate 100 includes: GOA device region 110, first set of clock lines 120, and second set of clock lines 130.
The GOA device region 110 has a plurality of GOA devices disposed therein, the first clock line group 120 including one or more clock lines, and the second clock line group 130 including one or more clock lines; the input end of each GOA device is respectively connected with the corresponding clock line, and the output end of each GOA device is connected with the corresponding scanning line. The first clock line group 120 is disposed on a first side of the GOA device region 110, the second clock line group 130 is disposed on a second side of the GOA device region 110, and the first side and the second side of the GOA device region 110 are opposite sides. By arranging the clock lines on the first side and the second side of the GOA device region 110 respectively, the structure effectively reduces the number of overlines among the clock lines, and reduces potential accumulation among the clock lines when the display panel works or works for a long time, thereby reducing breakdown risk among the clock lines and improving the cross grain and black screen phenomena of the display panel.
In the present embodiment, the number of clock lines in the first clock line group 120 and the second clock line group 130 is not limited. For example, in a display panel for an 8CK drive signal, the number of clock lines in the first clock line group 120 and the second clock line group 130 may be 4; referring to fig. 3, at this time, GOA1 to GOA4 are correspondingly connected to each clock line in the first clock line group 120, GOA9 to GOA12 are correspondingly connected to each clock line in the first clock line group 120, and so on; GOA 5-GOA 8 are correspondingly connected to each of the second set of clock lines 130, GOA 13-GOA 16 are correspondingly connected to each of the second set of clock lines 130, and so on. In addition, the number of clock lines in the first clock line group 120 and the second clock line group 130 may also be different. For example, the number of clock lines in the first clock line group 120 may be 3, and the number of clock lines in the second clock line group 130 may be 5; at this time, GOA1 to GOA3 are correspondingly connected to each clock line in the first clock line group 120, GOA9 to GOA11 are correspondingly connected to each clock line in the first clock line group 120, and so on; GOA 4-GOA 8 are correspondingly connected with each clock line in the second clock line group 130, GOA 12-GOA 16 are correspondingly connected with each clock line in the second clock line group 130, and so on; not shown in the drawings. Similarly, in the display panel for 16CK driving signals, the number of clock lines in the first clock line group 120 and the second clock line group 130 may be the same or different, and is not limited.
In a preferred implementation, the number of clock lines in the first set of clock lines 120 and the second set of clock lines 130 is the same. In this case, since the clock lines are uniformly distributed on both sides of the GOA device region 110, after the display panel starts to operate, potential accumulation on the clock lines caused by the driving signals on either side is effectively reduced, and breakdown risk between the clock lines is reduced; meanwhile, for any clock line, the number of possible breakdown other clock lines is reduced from 7 to 3 at present, so that the risk of breakdown is further reduced.
In some embodiments, when the positions of the clock lines are set, the positions may be determined according to waveforms of the driving signals corresponding to the clock lines, or in other words, waveforms of the driving signals of the clock lines distributed on two sides of the GOA device may satisfy the following conditions: the clock lines in the first clock line group 120 are in one-to-one correspondence with the clock lines in the second clock line group 130, and the clock pulse waveforms input on the corresponding two clock lines are inverted. For example:
referring to fig. 2 and 3, the pulse waveforms of the CK1 signal and the CK5 signal are inverted, the pulse waveforms of the CK2 signal and the CK6 signal are inverted, the pulse waveforms of the CK3 signal and the CK7 signal are inverted, and the pulse waveforms of the CK4 signal and the CK8 signal are inverted. When the clock pulse waveforms of the two clock lines are in opposite phases, the potential accumulation time between the two clock lines is longest, and breakdown risks are more likely to occur; at this time, clock lines corresponding to CK1 signal, CK2 signal, CK3 signal and CK4 signal may be disposed on one side of the GOA device region 110, and clock lines corresponding to CK5 signal, CK6 signal, CK7 signal and CK8 signal may be disposed on the other side of the GOA device region 110, so that clock lines with completely inverted clock waveforms may be disposed on both sides of the GOA device region 110, thereby effectively reducing breakdown risk between the clock lines.
In some embodiments, the time interval between rising edges of clock pulses input by each adjacent two clock lines in the first clock line group 120 is 2H; the time interval between the rising edges of the clock pulses input by every two adjacent clock lines in the second clock line group 130 is 2H; wherein H represents a time period required to scan 1 line in the display panel while maintaining the original refresh rate. Likewise, the time interval between the rising edges of the clock pulses input by every two adjacent clock lines in the first clock line group 120 may be 3H; by this, the time interval between rising edges of clock pulses input by every two adjacent clock lines in the second clock line group 130 is 3H, and thus, various implementations can be obtained. By adopting the implementation mode, potential accumulation can be reduced, and breakdown risk between clock lines is reduced.
In this embodiment, in the case where two sets of clock lines are respectively disposed on two sides of the GOA device Area 110, the two sets of clock lines and the GOA devices connected thereto may have the following two implementation manners with respect to the Active Area (AA Area) 140 of the display panel: one is that the first clock line group 120, the second clock line group 130, and the GOA device region 110 are disposed on the same side of the active display region 140. The implementation can be effectively applied to a display panel driven by a single side or a display panel driven by two sides. Secondly, the GOA device region 110 includes a first GOA region 111 and a second GOA region 112, where GOA devices in the first GOA region 111 are correspondingly connected to clock lines in the first clock line group 120, and GOA devices in the second GOA region 112 are correspondingly connected to clock lines in the second clock line group 130; the first GOA area 111 and the first clock line group 120 are disposed on a first side of the active display area 140, and the second GOA area 112 and the second clock line group 130 are disposed on a second side of the active display area 140, such as the array substrate 200 shown in fig. 4. Specifically, the first GOA area 111 is disposed between the first clock line group 120 and the active display area 140, and the second GOA area 112 is disposed between the second clock line group 130 and the active display area 140. In the implementation mode, the two groups of scan lines are completely independent, so that the cross line between the clock line and the scan line is avoided, and the potential accumulation is effectively reduced.
Based on the same inventive concept, in yet another embodiment of the present application, there is also provided a display panel including the array substrate described in any one of the foregoing embodiments. The display panel adopts the array substrate structure, wherein the clock lines are arranged at two sides of the GOA device region.

All display panels including the array substrate according to the foregoing embodiments of the present application are within the scope of the present application.

All display devices including the array substrate according to the foregoing embodiments of the present application are within the scope of the present application.
It should be noted that, the display device may be: any product or component with display function such as a mobile phone, a liquid crystal panel, an OLED panel, electronic paper, a tablet computer, a television, a display, a notebook computer, a digital photo frame or a navigator.
