## Abstract

A display apparatus for a vehicle includes a screen on which an image is displayed. A projector projects the image to the screen, and a knob is rotatably disposed at one side of the screen. A vibration sensor senses a vibration and outputs a vibration signal. A controller determines a rotational direction and a rotational amount of the knob based on the vibration signal output from the vibration sensor.

## Claims

### Claim 1

A display apparatus having a knob, comprising:
a screen on which an image is displayed;
a projector projecting the image to the screen;
a knob rotatably disposed at one side of the screen, wherein the knob includes: a knob rotator; a plurality of reference protrusions provided at a first distance along an outer circumference of the knob rotator; and a plurality of directional protrusions provided at a second distance along the outer circumference of the knob rotator;
a vibration sensor sensing a vibration from the knob and outputting a vibration signal;
a controller configured to determine a rotational direction and a rotational amount of the knob based on the vibration signal output from the vibration sensor,
a first vibrator configured to generate a first vibration by friction with the reference protrusions; and
a second vibrator configured to generate a second vibration by friction with the directional protrusions,
wherein the vibration sensor senses the first vibration to output a first pulse and senses the second vibration to output a second pulse, and
wherein a level of the first pulse is different from a level of the second pulse and an output timing of the first pulse is different from an output timing of the second pulse.

### Claim 2 (depends on 1)

The display apparatus of claim 1, wherein the controller selects a pulse having a preceding output timing of the first pulse and the second pulse, and determines the rotational direction of the knob according to a selection result.

### Claim 3 (depends on 1)

The display apparatus of claim 1, wherein the controller calculates the rotational amount of the knob based on a number of the first pulse.

### Claim 4 (depends on 1)

The display apparatus of claim 1, wherein the controller calculates the rotational amount of the knob based on a number of the second pulse.

### Claim 5 (depends on 1)

The display apparatus of claim 1, wherein the first distance is the same as the second distance.

### Claim 6 (depends on 1)

The display apparatus of claim 1, wherein an installation height for the knob rotator of each of the plurality of reference protrusions is different from an installation height for the knob rotator of each of the plurality of directional protrusions.

### Claim 7 (depends on 1)

The display apparatus of claim 1, wherein the plurality of reference protrusions and the plurality of directional protrusions are made of rigid materials.

### Claim 8 (depends on 1)

The display apparatus of claim 1, wherein the first vibrator and the second vibrator are made of elastic materials.

### Claim 9 (depends on 1)

The display apparatus of claim 1, further comprising:
an application driver configured to execute an application function according to a control signal of the controller,
wherein the controller outputs the control signal corresponding to the rotational direction and the rotational amount of the knob.
