Mobile terminal and method of controlling a mobile terminal to display image upon receiving proximity touch input

Abstract

A mobile terminal and a method of controlling a mobile terminal are provided. According to one embodiment, a mobile terminal includes: a touch screen for displaying and receiving information; and a controller for: controlling the touch screen to display a lock screen upon the mobile terminal entering a lock screen state; and controlling the touch screen to display a preview image of each of at least one application executed before entering the lock screen state upon receiving a proximity touch input on the displayed lock screen.

What is claimed is: 
     
         1 . A mobile terminal comprising:
 a touchscreen; and
 a controller configured to: 
 cause the touchscreen to display a screen including a plurality of items; 
 cause the touchscreen to display a detailed screen when a touch received at a first item of the plurality of items is a first touch type, wherein the detailed screen includes detailed amount of data associated with the first item; 
 cause the touchscreen to display preview information when a touch received at a first item of the plurality of items is a second touch type, wherein the preview information is only a partial amount of data associated with the first item, wherein the partial amount of data is less than the detailed amount of data of the detailed screen, wherein an area of the preview information is less than an area of the screen including the plurality of items, and wherein the first touch type is different from the second touch type; 
 cause the touchscreen to maintain the displaying of the preview information while the touch of the second touch type is continued to be received; and 
 cause the touchscreen to stop the displaying of the preview information when the touch of the second touch type is released. 
   
     
     
         2 . The mobile terminal of  claim 1 , wherein the controller is further configured to:
 change a display characteristic of the screen while the touch of the second touch type is continued to be received.   
     
     
         3 . The mobile terminal of  claim 2 , wherein the controller is further configured to:
 change the display characteristic of the screen back to an initial display characteristic when the touch of the second touch type is released.   
     
     
         4 . The mobile terminal of  claim 1 , further comprising:
 a touch sensor configured to provide data according to a touch received at the touchscreen; wherein the controller is further configured to:   recognize touch pressure of the touch of the first touch type and touch pressure of the touch of the second touch type according to the data provided by the touch sensor,   wherein the touch pressure of the touch of the first touch type and the touch pressure of the touch of the second touch type are different.   
     
     
         5 . The mobile terminal of  claim 1 , wherein location of the touch of the first touch type and location of the touch of the second touch type are substantially same. 
     
     
         6 . The mobile terminal of  claim 1 , wherein the touch of the second touch type comprises a touch and drag input. 
     
     
         7 . The mobile terminal of  claim 1 , wherein the preview information is displayed in a pop-up window that obscures a portion of the screen including the plurality of items. 
     
     
         8 . The mobile terminal of  claim 7 , wherein the preview information in the pop-up window comprises more detailed information than information displayed in screen including the first item of the plurality of items. 
     
     
         9 . The mobile terminal of  claim 7 , wherein a size of the pop-up window is larger than a displayed size of first item of the plurality of items. 
     
     
         10 . The mobile terminal of  claim 7 , wherein the pop-up window is displayed using a portion of an execution screen of the first item of the plurality of items. 
     
     
         11 . The mobile terminal of  claim 7 , wherein a size of the pop-up window is variable according to a type, or quantity, of the preview information. 
     
     
         12 . The mobile terminal of  claim 7 , wherein the type of the preview information comprises at least one of text or image. 
     
     
         13 . The mobile terminal of  claim 1 , further comprising:
 a wireless communication unit, wherein each of the plurality of items comprise a task that was performed previously using the wireless communication unit,   wherein the task include at least one call task or a message task.   
     
     
         14 . The mobile terminal of  claim 1 , wherein the first touch type is a proximity touch received at the first item, and the second touch type is a contact touch received at the first item. 
     
     
         15 . A mobile terminal comprising:
 a touchscreen; and   a controller configured to:   cause the touchscreen to display a plurality of items;   cause the touchscreen to display a detailed screen when a touch received at a first item of the plurality of items is a first touch type, wherein the detailed screen includes a first amount of data associated with the first item;   cause the touchscreen to display a preview when a touch received at a first item of the plurality of items is a second touch type, wherein the preview is a partial amount of data associated with the first item, wherein the partial amount of data is less than the first amount of data of the detailed screen, wherein a displayed area of the preview is less than an area within which the plurality of items are displayed, and wherein the first touch type is different from the second touch type;   cause the touchscreen to maintain the displaying of the preview while the touch of the second touch type is continued to be received; and   cause the touchscreen to stop the displaying of the preview when the touch of the second touch type is no longer received.
