Abstract

The invention provides a display method of a display device, which comprises the steps of: receiving an input image input to the display device; displaying the input image on an effective display region of the display device, wherein the size of the input image is more than that of the effective display region of the display device; generating an identification image overlapped on the input image, wherein the identification image is different from the input image; determining position information of the effective display region of the display device relative to the input image through the identification image; obtaining size information of the effective display region; and regulating the size of the input image to adapt to the effective display region of the display device according to the position information and the size information of the effective display region.

Description

technical field [0001] The invention relates to a display method of a display device and a display device. Background technique [0002] Currently known display devices can display the input image in an appropriate size on the display device by reducing / enlarging the image output from a device such as a player. However, when using a display device to input an image, since many current display devices cannot provide the position information of its effective display area, or the position information of the effective display area provided is inaccurate, even if the resolution of the input image is supported by the display device The resolution will also cause the images displayed by such devices to be incomplete. [0003] A common phenomenon is to cut off the edge part of the input image. Especially display devices such as TVs and projectors with analog output interfaces such as composite (CVBS) interfaces and component (YCbCr) interfaces, as well as pseudo-full high-definiti...
