RCM shows device soon suitable for electric power measurement

The utility model provides a RCM shows device soon suitable for electric power measurement, includes the display refresh module, shows the interface buffer memory, still includes relatively module ofpixel. The utility model discloses refresh show the interface before, the pixel data through current frame of pixel comparison pair of module and the whole pixels of a back intra -frame carries out the comparison, selects the changed pixel of pixel value, updates to these pixels. Through such mode, the utility model discloses can reduce the pixel quantity that needs to update to original more below 110 of new method to reduce and refresh the load that shows the interface, reduce the consumption to system resource, avoid original line loss measurement terminal to refresh slowly, appear situations such as ghost image. 种适用于电力计量的RCM快显装置，包括显示刷新模块、显示界面缓存，还包括像素比较模块。本实用新型在刷新显示界面之前，通过像素比较模块对当前帧和后帧内全部像素点的像素数据进行比较，筛选出像素值有变化的像素点，针对这些像素点进行更新。通过这样的方式，本实用新型能够将需要更新的像素点数量降低至原先更新方式的1/10以下，从而降低刷新显示界面的负荷量，降低对系统资源的消耗，避免原先线损计量终端刷新缓慢、出现
