## Abstract

A display apparatus according to embodiments may comprise: a PCB comprising a plurality of layers having a circuit printed thereon; a plurality of driver ICs which transmit at least one signal and are attached to the inside of the PCB; a driver circuit connecting the driver ICs in a first direction; scan ICs included in the driver ICs, respectively; a scan circuit connecting the scan ICs in the first direction and not crossing the driver circuit; and a controller that controls at least one of the driver ICs, the driver circuit, and the scan circuit.

## Claims

### Claim 1

A display device, comprising:
a PCB including a plurality of circuit printed layers;
a plurality of driver ICs attached to the PCB to transmit at least one signal and including a plurality of scan ICs inside, respectively;
a driver circuit connecting a first driver IC and a second driver IC among a plurality of the driver ICs together in a first direction;
a scan circuit connecting a first scan IC included inside the first driver IC and a second scan IC included inside the second driver IC together in the first direction without crossing with the driver circuit; and
a controller controlling at least one of a plurality of the driver ICs, the driver circuit, or the scan circuit.

### Claim 2 (depends on 1)

The display device of claim 1, wherein a plurality of the driver ICs generate first to fourth signals, respectively and wherein the first to fourth signals includes different informations, respectively.

### Claim 3 (depends on 2)

The display device of claim 2, wherein the driver circuit includes a first circuit transmitting the first signal, a second circuit transmitting the second signal, a third circuit transmitting the third signal, and a fourth circuit transmitting the fourth signal and wherein the fourth circuit includes at least one sub-circuit.

### Claim 4 (depends on 3)

The display device of claim 3, wherein the first to third circuits are formed parallel to the first direction to connect a plurality of the driver ICs and wherein the at least one sub-circuit is configured so that a pattern in a direction different from the first direction exists twice or less when connecting the first driver IC and the second driver IC in the first direction.

### Claim 5 (depends on 3)

The display device of claim 3, wherein an area having the first and second driver ICs connected to each other therein has a rectangular shape and wherein the first to fourth circuits exist only within a first area having the first and second driver ICs connected to each other therein.

### Claim 6 (depends on 5)
