A control method of a laundry treating apparatus, the laundry treating apparatus comprising: a first treating unit performing at least one of a wash cycle configured to remove foreign substances from clothes and a dry cycle configured to dry moisture from clothes; a second treating unit provided adjacent to the first treating unit and independently performing at least one of the wash cycle and the dry cycle; and a display unit; wherein the control method comprises: - a sense step for sensing whether the first treating unit is activated and/or the second treating unit is activated; - a select request step for displaying select information on the display unit so as to allow the user to select at least one of the first and second treating units (110, 120), wherein the select information includes at least one of first select information for selecting the first treating unit and second select information for selecting the second treating unit; - a course display step for displaying the operation command performable in the selected treating unit (110, 120) on the display unit, when the select information is selected; and - a process display step for displaying a processing state of an operation performed based on the operation command in the selected treating unit (110, 120) on the display unit, wherein the display unit is used for displaying a state of at least one treating unit (110, 120) or receiving an operation command for performing at least one of the wash and dry cycles; and wherein the select request step separately displays the first select information and the second select information on a first region and a second region, respectively, when the sense step senses that the first treating unit and the second treating unit are activated, wherein the first region and the second region are provided next to each other on the display unit, and the select request step displays only the select information (S210, S220) of the activated treating unit (110, 120) on a third region combining at least a part of the first and second regions (210, 220), when the sense step senses that only one of the first and second treating units (110, 120) is activated. a first treating unit performing at least one of a wash cycle configured to remove foreign substances from clothes and a dry cycle configured to dry moisture from clothes;
