Abstract
A display apparatus and a controlling method thereof are provided. The method of controlling the display apparatus including a plurality of LED devices, includes determining whether a plurality of LED devices are open using, for example, a pin voltage connected to the plurality of LED devices, in response to an open LED device being present, determining a coordinate of the open LED device, processing an image so that a particular color is output in an area where the open LED device is located, and outputting the processed image.
Claims12
A method of controlling a display apparatus comprising a plurality of light emitting diode (LED) devices, the method comprising:
- determining whether any of the plurality of LED devices are open;
- in response to an determining that an open LED device is present, determining a coordinate of the open LED device;
- processing an image to output a black color in an area where the open LED device is located based on the determined coordinate of the open LED device;
- and
- outputting the processed image.
A display apparatus, comprising:
- a plurality of LED devices;
- a driver configured to operate the plurality of LED devices, and to determine whether any of the plurality of LED devices are open;
- image signal converting circuitry configured to determine a coordinate of an open LED device, in response to an open LED device being present;
- and
- a processor configured to process an image to output a black color in an area where the open LED device is located based on the determined coordinate of the open LED device, and to control the image signal converting circuitry to convert the processed image to a signal processable by the driver.
