Displaying equipment and displaying method capable of quick displaying and system-failure backup mechanism

A displaying equipment capable of quick displaying and system-failure backup mechanism, comprising:

• an image input port, connected to an image sensitive device to continuously receive an input image;
• an image output unit;
• an image controlling module, connected with the image input port and the image output unit, and configured to continuously receive the input image from the image input port and immediately control the image output unit to continuously output the input image after the image controlling module activates completely;
• a primary system module, connected with the image controlling module, configured to run an operating system (OS) after being activated, and configured to perform an image processing procedure to the input image to generate a processed image, and to continuously transmits the processed image to the image controlling module, wherein an activation completing time of the primary system module is later than or equal to an activation completing time of the image controlling module;
• and
• a system controlling module, connected with the image controlling module and the primary system module, configured to continuously monitor the primary system module after the system controlling module activates completely;
• wherein, the image controlling module is configured to control the image output unit to output both the input image and the processed image after receiving the processed image, and configured to control the image output unit to only output the input image when the primary system module is determined to be abnormal.
