Disclosed are a display apparatus, a drive chip, and an electronic device. When determining that a disconnected signal line exists, the drive chip sends a control signal to a signal line repair module, so that when a shift output end of the first shift unit corresponding to the disconnected signal line outputs an enable signal, a selector switch corresponding to the shift output end is turned on, and then a connection control unit keeps outputting a turn-on signal to a control end of a corresponding connection switch.

The present invention relates generally to an LED sign system use on roadways, and more particularly to a LED sign system for use on roadways with a redundant controller.

External compensation of display panels may employ measurement or sensing circuitry configured to measure the output of a pixel and compensate for variations. Due to effects from the sensing circuitry, a mismatch between a target current and the actual current in the pixel may occur. Systems and methods that compensate for the effects from sensing circuitry and reduce or mitigate the mismatch are described. Systems and methods described herein include compensation circuitry that is capable of employing correction factors to compensate for the effects due to the presence of sensing circuitry. Methods for determining the correction factor are also described.

Display panel redundancy schemes and redundancy building blocks are described. In an embodiment, pixel driver chips are connected to both primary and redundant strings of LEDs within a local passive matrix, and driver terminal switches within the pixel driver chip are used to select either the primary or redundant strings of LEDs.
