Array substrate and display device

Abstract

The invention relates to an array substrate and a display device. The array substrate comprises a display region and a peripheral region. The array substrate comprises a plurality of data lines arranged within the display region, and signal transmission layout lines which correspond to the data lines one by one, are arranged within the peripheral region, and are used for transmitting a driving signal sent out of a driving unit to the corresponding data lines; each signal transmission layout line comprises at least one pair of first sub-layout lines; and in any one pair of the first sub-layout lines, the driving signal is transmitted in one first sub-layout line along the direction which is near the display region, and is transmitted along the direction which is far away from the display region in the other one first sub-layout line. The array substrate and display device disclosed by invention have the beneficial effects that the distances among the data lines can be increased, the inductive effect among the data lines can be weakened, the inductive effect which is along the direction perpendicular to the edge of the display region near output ends of the data lines can be weakened particularly, the crosstalk among the data lines can be reduced, and the signal transmission quality on the data lines can be improved.

Description

technical field [0001] The present invention relates to the technical field of Thin Film Transistor Liquid Crystal Display (TFT-LCD), in particular to an array substrate and a display device. Background technique [0002] TFT-LCD has the characteristics of small size, low power consumption, and no radiation, and occupies a dominant position in the current flat panel display market. [0003] Such as figure 1 As shown, the current TFT-LCD (Thin Film Transistor Liquid Crstal Display) array (array) substrate fan-out area (peripheral area) data (data) line leads mostly use serpentine lines (zigzag) to match the data lines The impedance between them reduces the time offset between the same group of signals. [0004] However, there are still insurmountable shortcomings in the zigzag method so far: [0005] Due to the influence of the inductance effect inside the zigzag data line and between adjacent data lines, the crosstalk between the same data line and the data line is seriou...

AI Technical Summary

Problems solved by technology

[0005] Due to the influence of the inductance effect inside the zigzag data line and between adjacent data lines, the crosstalk between the same data line and the data line is serious, and the quality of the transmission signal will be seriously affected, especially when the data line is in the In the direction perpendicular to the edge of the display area near the output end of the data line, the inductance effect on the data line is not weakened, but is always superimposed, which greatly increases the crosstalk between the data lines
