Abstract
Disclosed in the present disclosure are a method and apparatus for partial refreshing at arbitrary position on an electronic shelf label. The method includes: dividing positional regions of pixels of a target image in an electronic shelf label, and non-refresh-required pixels are assigned to an identical positional region, and pixels which have identical pixel transition requirements are assigned to another identical positional region; determining a code of each positional region and a drive waveform corresponding to the code; and refreshing the pixels of the target image according to the drive waveform. The present disclosure can achieve partial refreshing at arbitrary position on the electronic shelf label.
Claims16
A method for partial refreshing at arbitrary position on an electronic shelf label, comprising:
- dividing positional regions of pixels of a target image in an electronic shelf label, wherein non-refresh-required pixels are assigned to an identical positional region, and pixels which have identical pixel transition requirements are assigned to another identical positional region;
- determining a code of each positional region and a drive waveform corresponding to the code;
- and
- refreshing the pixels of the target image according to the drive waveform.
An apparatus for partial refreshing at arbitrary position on an electronic shelf label, comprising:
- a positional region division module configured to divide positional regions of pixels of a target image in an electronic shelf label, wherein non-refresh-required pixels are assigned to an identical positional region, and pixels which have identical pixel transition requirements assigned to an identical positional region;
- a code and drive waveform determination module configured to determine a code of each positional region and a drive waveform corresponding to the code;
- and
- a refreshing module configured to refresh the pixels of the target image according to the drive waveform.
A computer device, comprising a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor to be programmed by the computer program to:
- divide positional regions of pixels of a target image in an electronic shelf label, wherein non-refresh-required pixels are assigned to an identical positional region, and pixels which have identical pixel transition requirements are assigned to another identical positional region;
- determine a code of each positional region and a drive waveform corresponding to the code;
- and
- refresh the pixels of the target image according to the drive waveform.
