Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0033] An embodiment of the present invention provides a display method, see figure 2 , including:

[0034] Step 201, determine whether the video layer needs scaling, if so, then perform step 202, otherwise end;

[0035] Step 202, configuring the video layer as an online mode or an offline mode according to a preset policy;

[0036] Among them, the online mode can mean that the scaling engine of the display controller adopts real-time scaling. It can be understo...

Abstract

The embodiment of the invention discloses a display method and devices thereof. The display method comprises: when a video layer needs a video image to be scaled, whether a predetermined strategy is satisfied is judged, when the predetermined strategy is satisfied, an offline mode is adopted; when the predetermined strategy is not satisfied, an online mode is adopted; a video frame image is processed according to the online mode or the offline mode, the processed video image is output, the online mode means that when the video frame image is zoomed, the real time zooming is carried out, and the offline mode means that when the video frame image is zoomed, the asynchronous processing is adopted. The display method and the device provided by the embodiment of the invention realize the arbitrary proportional zoom of the original video image by selecting the online mode or offline mode and optimize the display power consumption.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display method, a display controller and a display terminal. Background technique [0002] At present, the application of video playback and video telephony on mobile terminals has become more and more common. In order to meet the requirements of playing a video source with a large resolution on a liquid crystal display (LCD, Liquid Crystal Display) with a relatively low display resolution, a process of shrinking the source is generally required. On the contrary, if a low-resolution film source is played on a relatively high display resolution LCD, the film source needs to be enlarged. [0003] The scaling processing of the video source is completed by the scaling engine integrated in the display controller. see figure 1 , which is a schematic structural diagram of a display controller in the prior art. The display controller 120 is synchronized with the display fr...
