Since the thickness of the protective layer 13 is within a preset range, the gate driving region 102 can be better protected.
结合图3和4，第一框胶12设置在所述第一基板20和所述第二基板10之间，且所述第一框胶12位于所述第一框胶区。其中左侧的第一框胶12位于显示区102的左侧；右侧的第一框胶12位于显示区102的右侧。可以理解的，图3为图4中右侧的栅极驱动区102和显示区101的结构示意图。3 and 4, the first sealant 12 is disposed between the first substrate 20 and the second substrate 10, and the first sealant 12 is located in the first sealant area. The first sealant 12 on the left is located on the left side of the display area 102; the first sealant 12 on the right is located on the right side of the display area 102. It can be understood that FIG. 3 is a schematic structural diagram of the gate driving region 102 and the display region 101 on the right side in FIG. 4.
如图4所示，所述第一框胶12的端部与所述第二框胶11抵接。其中两个所述第一框胶12分别沿所述第二基板10的两侧排布，也即其中一个第一框胶12沿所述第二基板10的一侧排布。在一实施方式中，栅极驱动区102位于第二基板10的左右侧时，此时第一框胶12沿第二基板10的宽度方向排布，第一框胶12的上下端部均与第二框胶11抵接。在另一实施方式中，栅极驱动区102也可位于第二基板10的上下侧时，第一框胶12沿第二基板10的长度方向排布，第一框胶12的左右端部均与第二框胶11抵接。As shown in FIG. 4, the end of the first sealant 12 is in contact with the second sealant 11. Two of the first sealants 12 are arranged along both sides of the second substrate 10, that is, one of the first sealants 12 is arranged along one side of the second substrate 10. In one embodiment, when the gate driving region 102 is located on the left and right sides of the second substrate 10, the first sealant 12 is arranged along the width direction of the second substrate 10, and the upper and lower ends of the first sealant 12 are both The second frame glue 11 abuts. In another embodiment, when the gate driving region 102 is located on the upper and lower sides of the second substrate 10, the first sealant 12 is arranged along the length of the second substrate 10, and both the left and right ends of the first sealant 12 are Contact with the second sealant 11.
当然，可以理解的，第二基板10也可仅包括一个栅极驱动区102以及一个第一框胶区，此时栅极驱动区102位于第二基板10的左侧或者右侧。第一框胶12位于所述显示区101的左侧或者右侧。具体设置方式与图3相似。Of course, it can be understood that the second substrate 10 may also include only one gate driving region 102 and one first sealant region. In this case, the gate driving region 102 is located on the left side or the right side of the second substrate 10. The first sealant 12 is located on the left or right side of the display area 101. The specific setting method is similar to Figure 3.
第二框胶11设置在所述第一基板20和所述第二基板10之间，且所述第二框胶11位于所述栅极驱动区102的外侧，也即远离显示区101的一侧，且靠近第二基板10的边缘。也即第二框胶11较第一框胶12更远离显示区101。如图4所示，第二框胶11为环状结构，其环绕在所述栅极驱动区102以及显示区101的外侧。The second sealant 11 is disposed between the first substrate 20 and the second substrate 10, and the second sealant 11 is located outside the gate driving region 102, that is, a portion away from the display region 101 Side, and close to the edge of the second substrate 10. That is, the second sealant 11 is farther away from the display area 101 than the first sealant 12. As shown in FIG. 4, the second sealant 11 is a ring-shaped structure, which surrounds the gate driving region 102 and the display region 101.
可以理解的，本发明的显示面板可以为液晶显示面板或者有机发光二极管显示器。It can be understood that the display panel of the present invention may be a liquid crystal display panel or an organic light emitting diode display.
本发明还提供一种上述显示面板的修复方法，具体用于对显示面板的栅极驱动区进行修复，该方法包括：The invention also provides a method for repairing the above display panel, which is specifically used for repairing the gate driving area of the display panel. The method includes:
S101、将第一部分去除；S101. Remove the first part;
例如，如图3所示，所述第一基板20包括至少一第一部分21和第二部分22，所述第一部分21与所述第一框胶区的外侧的区域的位置对应，且所述第一框胶区的外侧的区域远离所述显示区101；也即所述第一部分21覆盖所述栅极驱动区102。所述第二部分22覆盖所述显示区101和所述第一框胶区。For example, as shown in FIG. 3, the first substrate 20 includes at least a first portion 21 and a second portion 22, the first portion 21 corresponds to the position of the area outside the first frame area, and the The area outside the first frame area is away from the display area 101; that is, the first portion 21 covers the gate driving area 102. The second portion 22 covers the display area 101 and the first frame area.
如图5所示，具体地，将所述第一部分21切割掉，只剩下第二部分22。As shown in FIG. 5, specifically, the first part 21 is cut away, and only the second part 22 remains.
S102、去除所述保护层，并对所述栅极驱动区进行修复；S102. Remove the protective layer and repair the gate driving region;
例如，如图6所示，将所述栅极驱动区102上的保护层13去除，将栅极驱动区102裸露在外。比如当信号线出现故障时，对栅极驱动区102的信号线进行检测并修复。当然，如果栅极驱动区102的栅极驱动电路出现故障，也可对栅极驱动电路进行修复。For example, as shown in FIG. 6, the protective layer 13 on the gate driving region 102 is removed, and the gate driving region 102 is exposed. For example, when the signal line fails, the signal line of the gate driving region 102 is detected and repaired. Of course, if the gate driving circuit of the gate driving region 102 fails, the gate driving circuit can also be repaired.
S103、在所述修复后的栅极驱动区的上方制作平坦层。S103, forming a flat layer above the repaired gate driving region.
例如，在修复完成后，如图7所示，在所述修复后的栅极驱动区102的上方制作平坦层14，以对栅极驱动区102进行保护，防止其损坏。For example, after the repair is completed, as shown in FIG. 7, a flat layer 14 is formed on the repaired gate driving region 102 to protect the gate driving region 102 from damage.
在一实施方式中，所述平坦层14的上表面与所述第二部分22的上表面齐平，以使显示面板的上表面齐平。In one embodiment, the upper surface of the flat layer 14 is flush with the upper surface of the second portion 22 so that the upper surface of the display panel is flush.
其中，所述平坦层14位于所述栅极驱动区102和所述第二框胶11的上方。也即所述平坦层14覆盖所述栅极驱动区102以及所述第二框胶11。The flat layer 14 is located above the gate driving region 102 and the second sealant 11. That is, the flat layer 14 covers the gate driving region 102 and the second sealant 11.
在一实施方式中，为了更好地防止栅极驱动区受损，所述平坦层14为防潮绝缘胶，比如为塔菲（tuffy）胶。In one embodiment, in order to better prevent damage to the gate driving region, the flat layer 14 is a moisture-proof insulating adhesive, such as tuffy adhesive.
由于，在栅极驱动区的上方制作保护层，并使用框胶将栅极驱动区和显示区进行隔离，当需要对栅极驱动区进行测试与修复时，去掉栅极驱动区上方的基板和保护层，对其进行修复，从而降低了产品良率，避免产品报废，进而降低了生产成本。Since a protective layer is formed above the gate driving area, and the gate driving area is isolated from the display area using a sealant, when the gate driving area needs to be tested and repaired, the substrate and the gate driving area are removed. Protect the layer and repair it, thereby reducing the product yield and avoiding product scrapping, thereby reducing production costs.
