Abstract

The invention relates to a driving integrated circuit with A fan-out line compensation design, and the circuit comprises a plurality of driving lines, a signal input unit and a compensation unit. Thedriving lines are arranged along a first direction. Each driving circuit is provided with an input end and an output end. The signal input unit is electrically connected with the input end and provides a driving signal. The plurality of connection pads are arranged corresponding to the driving circuit, and each connection pad is electrically connected with the output end. The compensation unit isarranged on the driving circuit. The driving signal is transmitted to the connecting pad through the compensation unit. The drive circuit has a time constant distribution in a first direction that varies in a first curve. The compensation unit has a second curve change based on the first curve, and the second curve and the first curve have opposite trend changes.

Description

technical field

[0001] The present invention relates to driver integrated circuits; in particular, the present invention relates to driver integrated circuits for display devices. Background technique

[0002] In a display device, a driving integrated circuit (such as a source driver) is connected to a wire (such as a data line) in the display substrate through a fan-out area formed around the display substrate. With the improvement of display quality, the number of wires in the display substrate also increases, which makes the distance between the central part and the edge part of each group of fan-out areas larger, and has different degrees of resistance-capacitance effects. This will affect the display quality.

[0003] For the lines inside the driver integrated circuit, as the number of external (fan-out) lines increases, the number of lines inside the driver integrated circuit also increases, so that the internal lines also have different degrees of resistance-capacita...
