## Abstract

In examples, an electronic device comprises a camera and a display having a transparent area aligned with the camera. The display comprises a first line corresponding to a pixel row or column of the display, the first line extending from a first end of the display to the transparent area. The display comprises a second line corresponding to the pixel row or column and extending from a second end of the display to the transparent area, the first and second lines separated by a gap. The electronic device includes a controller coupled to the display, the controller to drive the first and second lines consecutively.

## Claims

### Claim 1

An electronic device, comprising:
a camera;
a display having a transparent area aligned with the camera, the display comprising:
a first line corresponding to a pixel row or column of the display, the first line extending from a first end of the display to the transparent area; and
a second line corresponding to the pixel row or column and extending from a second end of the display to the transparent area, the first and second lines separated by a gap;
a first drive interface at the first end of the display;
a second drive interface at the first end of the display; and
a controller coupled to the display,
wherein the controller is to drive the first line via the first drive interface and the second line via the second drive interface consecutively.

### Claim 2 (depends on 1)

The electronic device of claim 1, wherein the first and second lines are a pair of gate lines positioned in a same row in the display.

### Claim 3 (depends on 1)

The electronic device of claim 1, wherein the first and second lines are source lines.

### Claim 4 (depends on 1)

The electronic device of claim 1, wherein the display comprises:
a third line corresponding to a second pixel row or column of the display that is consecutive with the pixel row or column, the third line extending from the first end to the second end without passing through the transparent area, the third line composed of an opaque material,
wherein the controller is to drive the third line consecutive with the first line.

### Claim 5 (depends on 1)

The electronic device of claim 1, wherein the display comprises:
a third line corresponding to a second pixel row or column of the display, the third line extending from the first end to an area of the display without passing through the transparent area, the third line composed of an opaque material; and
a fourth line corresponding to the second pixel row or column, the fourth line extending from the second end to the area of the display without passing through the transparent area, the fourth line composed of the opaque material,
wherein the controller is to drive the third and fourth lines consecutively.

### Claim 6 (depends on 1)

The electronic device of claim 1, wherein the first line is composed of a transparent material and an opaque material, and wherein the second line is composed of the transparent material and the opaque material.

### Claim 7 (depends on 1)

The electronic device of claim 1, wherein the display comprises a first group of lines and a second group of lines, the first and second lines belonging to the second group of lines, wherein the controller is to drive the first group of lines according to a first consecutive pattern and the second group of lines according to a second consecutive pattern that differs from the first consecutive pattern.

### Claim 8

An electronic device, comprising:
a display having a transparent area, the display comprising:
a first gate line corresponding to a first pixel row of the display, the first gate line composed of an opaque material;
a second gate line corresponding to a second pixel row of the display that is consecutive with the first pixel row, the second gate line extending from a first end of the display to the transparent area, the second gate line composed of the opaque material and a transparent material; and
a third gate line corresponding to the second pixel row and extending from a second end of the display to the transparent area, the third gate line composed of the opaque and transparent materials; and
a controller coupled to the display, the controller to drive the first and second gate lines consecutively and the second and third gate lines consecutively,
wherein the second and third gate lines are separated by a gap.

### Claim 9 (depends on 8)

The electronic device of claim 8, the display comprising:
a first source line corresponding to a first pixel column of the display and extending from a third end of the display to the transparent area, the first source line composed of the opaque material and the transparent material; and
a second source line corresponding to the first pixel column and extending from a fourth end of the display to the transparent area, the second source line composed of the opaque material and the transparent material,
wherein the controller is to drive the first and second source lines consecutively.

### Claim 10 (depends on 8)

The electronic device of claim 8 comprising a camera positioned behind the transparent area.

### Claim 11

A non-transitory computer-readable medium storing machine-executable instructions, which, when executed by a controller, causes the controller to:
drive a first gate line of a display, the first gate line corresponding to a pixel row of the display and extending from a first end of the display to an area of the display; and
drive a second gate line of the display, the second gate line corresponding to the pixel row and extending from a second end of the display to the area, the controller is to drive the first gate line within two gate time periods of the second gate line; and
drive a third line consecutive with the first gate line, the third line corresponding to a second pixel row or column of the display that is consecutive with the pixel row or column, the third line extending from the first end to the second end without passing through a transparent area, the third line composed of an opaque material,
wherein the first and second gate lines extend into the transparent area of the display.

### Claim 12 (depends on 11)

The non-transitory computer-readable medium of claim 11, wherein the instructions, when executed by the controller, cause the controller to drive the second gate line consecutively with the first gate line.

### Claim 13 (depends on 11)

The non-transitory computer-readable medium of claim 11, wherein the instructions, when executed by the controller, cause the controller to drive the first gate line non-consecutively with the second gate line.

### Claim 14 (depends on 11)

The non-transitory computer-readable medium of claim 11, wherein the instructions, when executed by the controller, cause the controller to:
drive a third line corresponding to a second pixel row or column of the display, the third line extending from the first end to an area of the display without passing through the transparent area, the third line composed of an opaque material; and
drive a fourth line consecutive with the third line, the fourth line corresponding to the second pixel row or column, the fourth line extending from the second end to the area of the display without passing through the transparent area, the fourth line composed of the opaque material.
