The data display method includes setting a scroll rate to a touch movement distance; detecting a touch gesture in a first region of the touchscreen; scrolling icons in the first region at the scroll rate in response to the touch gesture; and displaying detailed information associated with at least one icon newly displayed according to the scroll in a second region of the touchscreen. ## Claims ### Claim 1 A data display method of an electronic device having a touchscreen, the method comprising: detecting a first touch gesture in a first region of the touchscreen; setting a scroll rate based on a touch movement distance of the first touch gesture in the first region; detecting a second touch gesture in a second region of the touchscreen; scrolling icons in the first region at the scroll rate in response to the second touch gesture to display at least one newly displayed icon with the disappearance of at least one previously displayed icon in the first region; and displaying detailed information associated with one of the at least one newly displayed icon in the second region of the touchscreen, wherein the setting comprises adjusting a number of icons to be displayed in the first region based on the scroll rate. ### Claim 2 (depends on 1) The method of claim 1, wherein the first touch gesture is a multi-touch gesture. ### Claim 3 (depends on 2) The method of claim 2, wherein the setting comprises setting the scroll rate to a first value when the multi-touch gesture is a pinch-in gesture and a second value less than the first value when the multi-touch gesture is a pinch-out gesture. ### Claim 4 (depends on 3) The method of claim 3, wherein the adjusting comprises increasing the number of icons to be displayed in the first region for the pinch-in gesture and decreasing the number of icons to be displayed in the first region for the pinch-out gesture. ### Claim 5 (depends on 2) The method of claim 2, wherein the setting comprises setting the scroll rate to a first value when the multi-touch gesture is a pinch-out gesture and a second value less than the first value when the multi-touch gesture is a pinch-in gesture. ### Claim 6 A data display method of an electronic device having a touchscreen, the method comprising: displaying icons in a first region of the touchscreen and detailed information in a second region of the touchscreen, with the detailed information being associated with one of the displayed icons; changing a current display level of all of the icons in the first region, with the display level associated with a hierarchy, in response to a pinch gesture, in the second region; and displaying detailed information of one of the icons with the changed display level in the second region. ### Claim 7 (depends on 6) The method of claim 6, wherein the changing comprises: detecting a multi-touch gesture in one of the first and second regions. ### Claim 8 (depends on 7) The method of claim 7, wherein the changing comprises increasing the current display level to a higher level in the hierarchy when the multi-touch gesture is a pinch-in gesture and decreasing the current display level to a lower level in the hierarchy when the multi-touch gesture is a pinch-out gesture. ### Claim 9 (depends on 8) The method of claim 8, wherein the display levels in the hierarchy are associated with one of time and location. ### Claim 10 An electronic device comprising: a display unit which has a touchscreen including a first region for displaying icons and a second region for displaying detailed information; and a control unit which controls detecting a first touch gesture in the first region of the touchscreen, setting a scroll rate based on a touch movement distance of the first touch gesture in the first region, detecting a second touch gesture in the second region of the touchscreen, scrolling icons in the first region at the scroll rate in response to the touch gesture to display at least one newly displayed icon with the disappearance of at least one previously displayed icon in the first region, and displaying detailed information associated with one of the at least one newly displayed icon in the second region of the touchscreen, in response to a scroll, wherein the control unit controls adjusting a number of icons to be displayed in the first region based on the scroll rate. ### Claim 11 (depends on 10) The electronic device of claim 10, wherein the first touch gesture is a multi-touch gesture. ### Claim 12 (depends on 11) The electronic device of claim 11, wherein the control unit sets the scroll rate to a first value when the multi-touch gesture is a pinch-in gesture and a second value less than the first value when the multi-touch gesture is a pinch-out gesture. ### Claim 13 An electronic device comprising: a display unit with a touchscreen having a first region for displaying icons and a second region for displaying detailed information associated with one of the displayed icons; and a control unit which controls the display unit to change a current display level of all of the icons in the first region with the display level associated with a hierarchy, in response to a pinch gesture, in the second region and to display the detailed information of one of the icons with changed display level in the second region. ### Claim 14 (depends on 13) The electronic device of claim 13, wherein the control unit detects a multi-touch gesture in one of the first and second regions. ### Claim 15 (depends on 14) The electronic device of claim 14, wherein the control unit increases the current display level to a higher level in the hierarchy when the multi-touch gesture is a pinch-in gesture and decreases the current display level to a lower level in the hierarchy when the multi-touch gesture is a pinch-out gesture.
