and a controller configured to set the image display apparatus in a standby mode having the rollable display in a non-viewable retracted, in response to receiving a user input signal from the remote controller, transition the rollable display from the non-viewable retracted state to a partial view state having a first height and display at least one object on the rollable display, and in response to receiving a voice input while in the partial view state, transition the rollable display from the partial view state to a main view state having a second and display a content item corresponding to the voice input. ## Claims ### Claim 1 An image display apparatus comprising: a rollable display configured to display an image; a drive part configured to roll up or roll down the rollable display; a user input interface configured to receive a signal from a remote controller; and a controller configured to: set the image display apparatus in a standby mode after being powered on, the standby mode having the rollable display in a non-viewable retracted state without being exposed to an outside, in response to receiving a user input signal from the remote controller via the user input interface, transition the rollable display from the non-viewable retracted state to a partial view state having a first height exposing a first area of the rollable display to the outside and display at least one object on the first area of the rollable display, and in response to receiving a voice input from a user while in the partial view state, transition the rollable display from the partial view state to a main view state having a second height exposing a second area of the rollable display to the outside and display a content item corresponding to the voice input on the second area, wherein the second height is greater than the first height. ### Claim 2 (depends on 1) The image display apparatus according to claim 1, wherein a height of the content item corresponds to the second height of the rollable display. ### Claim 3 (depends on 1) The image display apparatus according to claim 1, wherein the at least one object includes a thumbnail list including a plurality of thumbnails, or the at least one object includes an application list including a plurality of application icons. ### Claim 4 (depends on 3) The image display apparatus according to claim 3, wherein a height of each of the plurality of thumbnails or each of the plurality of application icons corresponds to the first height of the rollable display. ### Claim 5 (depends on 3) The image display apparatus according to claim 3, wherein one of the plurality of thumbnails is displayed larger than a reminder of the plurality of thumbnails, or one of the plurality of application icons is displayed larger than a reminder of the plurality of application icons. ### Claim 6 (depends on 1) The image display apparatus according to claim 1, wherein the at least one object includes a voice recognition object. ### Claim 7 (depends on 1) The image display apparatus according to claim 1, further comprising an opening in a surface of the image display apparatus, wherein the rollable display is not exposed outside of the opening while in the standby mode. ### Claim 8 (depends on 1) The image display apparatus according to claim 1, wherein the content item is a video or a movie. ### Claim 9 (depends on 1) The image display apparatus according to claim 1, wherein the controller is further configured to: in response to the voice input failing to provide a search result or termination of a voice recognition mode, transition the rollable display from the partial view state to the standby mode having the rollable display in the non-viewable retracted state. ### Claim 10 (depends on 1) The image display apparatus according to claim 1, wherein the controller is further configured to increase a brightness of the rollable display as a height of the rollable display increases. ### Claim 11 (depends on 1) The image display apparatus according to claim 1, further comprising an audio output part, wherein the controller is further configured to increase a volume of the audio output part as a height of the rollable display increases. ### Claim 12 An image display apparatus comprising: a rollable display configured to display an image; a drive part configured to roll up or roll down the rollable display; a user input interface configured to receive a signal from a remote controller; and a controller configured to: set the image display apparatus in a standby mode having the rollable display in a non-viewable retracted state, in response to receiving a user input signal from the remote controller via the user input interface, transition the rollable display from the non-viewable retracted state to a partial view state having a first height and display at least one object on the rollable display, and in response to receiving a voice input from a user while in the partial view state, transition the rollable display from the partial view state to a main view state having a second height and display a content item corresponding to the voice input, wherein the second height is greater than the first height. ### Claim 13 (depends on 12) The image display apparatus according to claim 12, wherein a height of the content item corresponds to the second height of the rollable display. ### Claim 14 (depends on 12) The image display apparatus according to claim 12, wherein the at least one object includes a thumbnail list having a plurality of thumbnails, or the at least one object includes an application list including a plurality of application icons. ### Claim 15 (depends on 14) The image display apparatus according to claim 14, wherein a height of each of the plurality of thumbnails or each of the plurality of application icons corresponds to the first height of the rollable display. ### Claim 16 (depends on 14) The image display apparatus according to claim 14, wherein one of the plurality of thumbnails is displayed larger than a reminder of the plurality of thumbnails, or one of the plurality of application icons is displayed larger than a reminder of the plurality of application icons. ### Claim 17 (depends on 12) The image display apparatus according to claim 12, wherein the at least one object includes a voice recognition object. ### Claim 18 A method of controlling an image display apparatus having a rollable display, the method comprising: setting the image display apparatus in a standby mode after being powered on, the standby mode having the rollable display in a non-viewable retracted state without being exposed to an outside; in response to receiving a user input signal from a remote controller via a user input interface of the image display apparatus, transitioning the rollable display from the non-viewable retracted state to a partial view state having a first height exposing a first area of the rollable display to the outside and displaying at least one object on the first area of the rollable display; and in response to receiving a voice input from a user while in the partial view state, transitioning the rollable display from the partial view state to a main view state having a second height exposing a second area of the rollable display to the outside and displaying a content item corresponding to the voice input on the second area, wherein the second height is greater than the first height. ### Claim 19 (depends on 18) The method according to claim 18, wherein a height of the content item corresponds to the second height of the rollable display. ### Claim 20 (depends on 18) The method according to claim 18, wherein the at least one object includes a thumbnail list including a plurality of thumbnails, or the at least one object includes an application list including a plurality of application icons, and wherein a height of each of the plurality of thumbnails or a height of each of the plurality of application icons corresponds to the first height of the rollable display.
