Abstract

The present disclosure provides a display device and an electronic device. The display device includes a display panel and a source driving chip. The display panel includes a plurality of traces in a fan-shaped distribution. A plurality of signal output terminals and a plurality of compensation traces are disposed in the source driving chip. The compensation traces are configured to reduce a resistance difference among the plurality of traces in a fan-shaped distribution, and each signal output terminal is electrically connected to a corresponding one of the traces in a fan-shaped distribution using one corresponding compensation trace.

Claims (9)

1. A display device, comprising:

a display panel, comprising a plurality of traces in a fan-shaped distribution; and

a source driving chip, in which a plurality of signal output terminals and a plurality of compensation traces are disposed, wherein the compensation traces are configured to reduce a resistance value difference among the plurality of traces in a fan-shaped distribution, the plurality of traces in a fan-shaped distribution, the plurality of signal output terminals, and the plurality of compensation traces are in a one-to-one correspondence, and each signal output terminal is electrically connected to a corresponding one of the traces in a fan-shaped distribution using one corresponding compensation trace;

wherein lengths of a first compensation trace of the plurality of compensation traces to a middle compensation trace of the plurality of compensation traces increment, and lengths of the middle compensation trace to a last compensation trace of the plurality of compensation traces decrement.

2. The display device as claimed in claim 1 , wherein the plurality of traces in a fan-shaped distribution are arranged at intervals in a first direction, in the first direction, resistance values of a first one of the traces in a fan-shaped distribution to a middle one of the traces in a fan-shaped distribution decrement, and resistance values of the middle one of the traces in a fan-shaped distribution to a last one of the traces in a fan-shaped distribution increment;

resistance values of the first compensation trace to the middle compensation trace in a one-to-one correspondence with the first one of the traces in a fan-shaped distribution to the middle one of the traces in a fan-shaped distribution increment, and resistance values of the middle compensation trace to the last compensation trace in a one-to-one correspondence with the middle one of the traces in a fan-shaped distribution to the last one of the traces in a fan-shaped distribution decrement.

3. The display device as claimed in claim 2 , wherein widths of the plurality of compensation traces are equal.

4. The display device as claimed in claim 3 , wherein the compensation traces are in a shape of a broken line or a straight line.

5. The display device as claimed in claim 1 , wherein distances between the plurality of signal output terminals and the corresponding traces in a fan-shaped distribution are equal.
