Display apparatus and display method

A display apparatus, comprising:

• a display, configured to display an image and/or a user interface;
• a remote controller, comprising a plurality of keys and configured to:
• output an infrared signal carrying a first infrared key value in response to a selection of an integrated key from the user, wherein the integrated key is configured for replacing at least two omitted keys not disposed on the remote controller;
• a memory, configured to store instructions and data associated with the display;
• and
• at least one processor, in connection with the display and configured to respond a key event corresponding to a omitted key which is not disposed on the remote controller;
• wherein the at least one processor is configured to execute the instructions to cause the display apparatus to:
• identify an infrared key value of an infrared signal corresponding to the integrated key received from the remote controller;
• control the display to display a key interface in response to the infrared key value being the first infrared key value, wherein the key interface comprises at least two first controls corresponding to the at least two omitted keys, wherein one first control corresponds to one key omitted on the remote controller;
• and
• generate a target infrared key value in response to a selection of one of the at least two first controls from the user, wherein the target infrared key value is a key value of a omitted key corresponding to the selected first control.
