Abstract

The invention relates to a display device and an adjusting method thereof. The display device comprises a display panel and a driving module. The display panel comprises a display area and a fan-out area. A plurality of data lines are arranged in the display area and a plurality of connecting lines are arranged in the fan-out area. The driving module comprises a detection unit for detecting the resistance value of the connecting line. The connecting line comprises a first connecting line and a second connecting line; a plurality of source driving units, wherein the source driving units are internally integrated with adjustable resistors; and a control chip electrically connected with a plurality of source driving units through function pins, wherein the control chip is used for comparing the resistance values of the first connection line and the second connection line, and outputting a control signal according to the resistance value comparison result. The source driving unit receivesthe control signal, and adjusts the resistance value of the adjustable resistor according to the control signal, so that the resistance value of the first connection line and the second connection line in the fan-out region is the same.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and an adjustment method thereof. Background technique [0002] The general display principle of a traditional display device is to control each pixel to be turned on or off row by row through criss-cross gate lines and data lines on a TFT (Thin Film Transistor, Thin Film Transistor) substrate, so as to realize ideal image display. The gate drive signal and data signal that control the pixel to be turned on or off are sent from the control chip in the display device, and it is usually necessary to use COF (Chip On Film, chip-on-film) to transmit the gate drive signal and data signal to the TFT respectively. Gate lines and data lines on the substrate. The traditional processing method is fan-out layout. The so-called fan-out layout means that a part of the wires connecting the gate line and the data line is fan-shaped as a whole, and the length of the ...
