Picture local updating method, system and device for display equipment

Abstract

The invention discloses a picture local updating method, a system and a device for display equipment, and the method comprises the steps: firstly updating local data, corresponding to a target updating position, in stored full-screen picture data based on the target updating position of a full-screen picture of the display equipment, and then refreshing the display equipment in a full-screen manner based on the updated full-screen picture data. Visibly, the local picture information of the display equipment is updated by locally updating the picture data and refreshing the display equipment ina full-screen manner, so that the adverse effect of local picture refreshing can be avoided, and the storage space of the picture data can be repeatedly utilized to reduce the use of the storage space; in addition, the target updating position of the full-screen picture can be specified, so that the picture information updating flexibility of the display equipment is improved.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a method, system and device for updating a partial image of a display device. Background technique [0002] With the development of computer technology and communication technology, display devices (such as electronic tags) gradually rise and are widely used. At present, during the image refresh process of the display device, it is often necessary to update partial data, for example, please refer to figure 1 , figure 1 It is a display schematic diagram of a display device for displaying time and temperature and humidity in the prior art, for figure 1 For display devices, the data that needs to be updated frequently is generally only the last 1-2 digits. For example, if the temperature changes from 28.5°C to 28.6°C, the display device is usually refreshed by refreshing partial pictures. However, in the process of partial image refresh of the display device, the refresh is...

Problems solved by technology

However, in the process of partial image refresh of the display device, the refresh is prone to be unstable, and problems such as ghosting will occur.

[0003] Based on this, if the full-screen refresh method in the prior art is used, the adverse effects of partial image refresh can be avoided, but the existing full-screen refresh method needs to prepare data of different full-screen images in advance for replacement during full-screen refresh. For constantly updated display devices, too much image data needs to be prepared in advance, making it difficult to provide sufficient storage space for the image data
