Abstract

A display apparatus includes drivers included in first, second, and third driver groups in a peripheral area and disposed along a round corner of a display area. The first driver group includes a first driver electrically connected to a signal line on an i-th row, and a second driver adjacent to the first driver in a first arrangement direction and electrically connected to a signal line disposed on a (i+j)-th row (i<j). The second driver group includes a third driver electrically connected to a signal line disposed on an (i+n)-th row (j<n), and a fourth driver electrically connected to a signal line disposed on a (i+m)-th row (n<m) and adjacent to the third driver in a direction opposite to a first arrangement direction. A separation region is between the third driver group and the second driver group.

sub-pixel circuits disposed in the display area;
light-emitting diodes disposed in the display area and electrically connected to the sub-pixel circuits;
signal lines electrically connected to the sub-pixel circuits and each extending in a first direction in the display area; and
drivers disposed in the peripheral area and electrically connected to the signal lines, wherein
the drivers include:
a first driver group including a first driver and a second driver, the first driver being electrically connected to a signal line disposed on an i-th row (i is a natural number) among the signal lines, and the second driver being electrically connected to a signal line disposed on a (i+j)-th row (j is a natural number) among the signal lines and being adjacent to the first driver in a first arrangement direction;
a second driver group including a third driver and a fourth driver, the third driver being electrically connected to a signal line disposed on an (i+n)-th row (n is a natural number greater than j) among the signal lines, the fourth driver being electrically connected to a signal line disposed on a (i+m)-th row (m is a natural number greater than n) among the signal lines and being adjacent to the third driver in a direction opposite to the first arrangement direction; and
a third driver group adjacent to the second driver group in the first arrangement direction with a separation region between the second driver group and the third driver group, and
the first driver group, the second driver group, and the third driver group are disposed along the round corner of the display area.

2. The display apparatus of claim 1 , wherein
the second driver of the first driver group is a driver disposed closest to the second driver group,
the third driver of the second driver group is a driver disposed farthest away from the first driver group, and
a carry signal output from the second driver is transferred to the third driver through a carry signal line passing between the second driver group and an edge of the substrate.

3. The display apparatus of claim 1 , wherein the sub-pixel circuits each include:
a driving thin-film transistor;
a compensation thin-film transistor that electrically connects a gate of the driving thin-film transistor to a drain of the driving thin-film transistor; and
a control thin-film transistor electrically connected to the driving thin-film transistor.

4. The display apparatus of claim 3 , wherein the signal lines are electrically connected to a gate of the compensation thin-film transistor or a gate of the control thin-film transistor of each of the sub-pixel circuits.

5. The display apparatus of claim 1 , wherein
a driving signal output from the third driver is transferred to the signal line disposed on the (i+n)-th row through a first signal connection line passing across the separation region, and
a driving signal output from the fourth driver is transferred to the signal line disposed on the (i+m)-th row through a second signal connection line passing across the separation region.

6. The display apparatus of claim 5 , wherein a driving signal output from a driver disposed closest to the first driver group among drivers of the second driver group is transferred to a signal line disposed on an (i+p)-th row (p is a natural number greater than m) through a third signal connection line.

7. The display apparatus of claim 6 , further comprising:

a second portion of the common voltage supply line integrally connected to the first portion of the common voltage supply line is disposed between the first driver group and the edge of the substrate, and
a width of the second portion of the common voltage supply line is greater than a width of the first portion.

9. The display apparatus of claim 6 , wherein a carry signal output from the driver disposed closest to the first driver group among drivers of the second driver group is transferred to a driver disposed closest to the second driver group among drivers of the third driver group through a carry signal line passing across the separation region.

10. The display apparatus of claim 9 , wherein the driver disposed closest to the second driver group among drivers of the third driver group is electrically connected to a signal line disposed on an (i+q)-th row (q is a natural number greater than p) among the signal lines.

11. The display apparatus of claim 5 , further comprising:
