Abstract

The present application relates to a display device and its adjustment method. The display device includes a display panel and a drive module. The display panel includes a display area and a fan-out area. A plurality of data lines are arranged in the display area. The fan-out The region is provided with a plurality of connection lines; the drive module includes: a detection unit for detecting the resistance of the connection line; the connection line includes a first connection line and a second connection line; a plurality of source drive units, the An adjustable resistor is integrated inside the source drive unit; a control chip is electrically connected to a plurality of the source drive units through functional pins, and the control chip is used to compare the first connection line with the the resistance value of the second connection line, and output a control signal according to the resistance comparison result; the source drive unit receives the control signal, and adjusts the resistance value of the adjustable resistor according to the control signal, so that the The first connection line and the second connection line have the same resistance in the fan-out area.

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 ...
