Abstract

The invention provides a method for improving a display effect of an electronic ink display screen. The method comprises the following steps: a microcontroller receives, analyzes and encapsulates an image display request and interacts the image display request with a DSP (Digital Signal Processor) through an interaction protocol; the DSP calculates image data of an image to be displayed to obtain waveform data corresponding all data frames in the image to be displayed and stores the waveform data into an internal memory; the DSP starts a timer inside the DSP, carries out time computation and controls a display driven controller to read the waveform data from the internal memory and output the waveform data to an image display controller. When the display image is not completely displayed by the DSP, the microcontroller receives an interrupt request of peripheral equipment and cannot interrupt the process of outputting waveform data to the display drive controller by the DSP, so that the DSP is not influenced by the operation system switchoff interrupt request, the problem of output delay of the waveform data due to interrupt of the microcomputer is solved, the output time accuracy and the real-time property among all frames of waveform data is ensured, and thus a display effect is ensured.

Description

【Technical field】 [0001] The invention relates to a method for improving the display effect of an electronic ink display screen. 【Background technique】 [0002] E-ink display is a display that uses the principle of electrophoretic display. Numerous microcapsules are arranged inside the display, and each microcapsule is packed with two kinds of positively charged and negatively charged particles. The positively charged particles are white positive ions, and the negatively charged particles are black negative ions. Each microcapsule is arranged between two parallel electrodes. When the top electrode applies an electric field in one direction, black negative ions electrophoresis to the top of the capsule and accumulate, while white positive ions electrophoresis to the other end of the capsule. You can now see black on one side of the screen and white on the other. By applying different electric fields, users can see different display contents. [0003] The display refresh me...
