Abstract

The invention discloses a display method which comprises the following steps: acquiring first picture data to be displayed; processing the first picture data into K picture data blocks; acquiring second picture data with N frames, and displaying the second picture data with N frames for N times, wherein N is an integer which is larger than or equal to 2, and each of the second picture data with Nframes comprises X picture data blocks in the K picture data blocks and the rest processed X picture data blocks in the K picture data blocks. The invention also discloses a display device which comprises a storage module, a processing module and a display module, wherein the storage module is used for storing data; the processing module is used for processing the first picture data into the second picture data with N frames, and storing the second picture data with N frames into the storage module; and the display module is used for acquiring the second picture data with N frames from the storage module, and displaying the second picture data with N frames for N times. The display method can be used for solving the problem that the picture data is copied by screen capture.

Description

technical field [0001] The invention relates to display technology, in particular to a method and device for displaying picture data. Background technique [0002] There are roughly the following ways to capture the screen: capture the screen through the Print screen button, take a picture with a camera, capture the screen through the screen capture software, and capture the screen through the driver program to read and write the display memory.
