Array substrate and liquid crystal display panel

Abstract

The invention provides an array substrate and a liquid crystal display panel. The array substrate comprises a transparent substrate and a plurality of opaque distribution wires positioned on the transparent substrate; the plurality of distribution wires extend and pass through a frame glue area; random one of the plurality of distribution wires has periodical waveform bent patterns in the frame glue area; and the period of the waveform bent patterns of the distribution wires is staggered relative to the adjacent distribution wires. The liquid crystal display panel comprises the array substrate, an opposed substrate opposite to the array substrate and frame glue stuck between the two substrates; the frame glue is stuck to the frame glue area of the array substrate; the frame glue is sealedbetween the two substrates to form a display area; and a liquid crystal layer is filled in the display area. The frame glue is quickly cured without increasing the power consumption, so that the production efficiency is improved.

Problems solved by technology

In each "fan-shaped" connection area, the length of the wiring increases from the middle of the "fan-shaped" area to both sides, so that the resistance value (R) and coupling capacitance (C) of the wiring also increase from the middle of the "fan-shaped" area to the two sides. The two sides increase, so that the wiring has a different RC delay time, and the different RC delay time will cause the image quality of the liquid crystal display panel to degrade, such as the phenomenon of water ripples (mura). In order to make each wiring in the "sector" area have a For the same RC delay time, the current solution is to set one end of the wiring in the "sector" area or the wiring at the upper and lower ends as bent wiring, and compensate for the difference in length so that each wiring has a same RC delay time

figure 2 Yes figure 1 The enlarged view of the middle area 10, where the data lines 12 with periodically arranged square-wave bent wiring structure are coated with frame glue 3, the data lines 12 are essentially arranged along the longitudinal direction, and the frame glue 3 is cured by light In this case, since the data line 12 itself is opaque, it will block part of the light from passing through and affect the curing speed of the sealant 3

For example, in figure 2 The width of the horizontal narrow and long region 21 and the horizontal narrow and long region 22 is 1 / 4 period of the data line 12. However, since the horizontal narrow and long region 21 always has the short side of the square wave and bent trace, However, there is always a long side of a square-shaped bent line in the laterally long and narrow region 22, so it can be seen that the area occupied by the data lines 12 in the laterally long and narrow region 21 is smaller than the area occupied by the data lines 12 in the laterally long and narrow region 22, therefore, In the horizontal narrow and long area perpendicular to the longitudinal extension direction of the plurality of data lines, during the curing process of the sealant 3, the light-curing speed of the sealant 3 is slow due to the different areas irradiated by light and uneven illumination.

In addition, as figure 2 Although the widths of the longitudinally long and narrow regions 23 and 24 along the longitudinal extension direction of the plurality of data lines are both the line width of the data lines 12 with square waveforms, the longitudinally long and narrow regions 23 always have square The broad side of the waveform bends the wiring, and the narrow side of the square waveform bends in the longitudinal narrow region 24. Therefore, it can be seen that the area occupied by the data line 12 in the longitudinal narrow region 24 is smaller than that of the data line in the longitudinal narrow region 23. The area occupied by the line 12, therefore, in the longitudinal narrow and long region along the longitudinal extension direction of the plurality of data lines, there is also the problem of photocuring of the frame glue 3 during the curing process due to the different areas irradiated by light and uneven illumination. slower

[0006] At present, most of the solutions to the above problems are to increase the intensity or irradiation time of ultraviolet light, but this will result in increased power consumption or reduced production efficiency.
