Description
Technical Field
The application relates to the technical field of electrophoretic display, in particular to an image display refreshing method and device of an electrophoretic display screen and electronic equipment.
Background
An electrophoretic display (Electrophoretic Display, EPD for short) is an electronic ink display technology, also known as an electronic ink screen or ink screen, which can be used for flat panel display technology for displaying text and images, and is widely used in electronic book readers and certain visual information display devices.
Two electrode layers are respectively arranged at the bottom and the top of the electrophoretic display screen. When an electric field is applied between the two layers, the electronic ink particles are moved by the charge. If a positive electric field is applied to a certain area, the particles will move towards that area, making this area appear white; conversely, if a negative field is applied to a region, the particles will move apart, rendering the region black. The process of electronic ink display refresh includes control of the electric field. The arrangement of the ink particles is adjusted by changing the polarity and intensity of the electric field according to the image to be displayed, thereby presenting text and images.
However, when refreshing the display content of an electrophoretic display, a strong electric field needs to be re-established to move and rearrange the particles, and especially when frequent refreshing or large-area refreshing is required to consume additional electric power. Therefore, the refresh process of the electrophoretic display screen has a problem of high power consumption.
Therefore, there is a need for an image display refreshing method and apparatus for an electrophoretic display screen, and an electronic device.

Before describing embodiments of the present application, some terms referred to in the embodiments of the present application will be first defined and described.
An electrophoretic display screen: an electronic paper technology is used for manufacturing a display screen capable of repeatedly erasing and displaying static images. Its principle of operation is based on the electrophoretic effect, in which tiny particles move under the influence of an electric field, thereby changing the color state of the pixel. An electrophoretic display screen consists of tiny color particles (typically white particles) and a base substrate. These particles are suspended in a transparent liquid or gel medium, which typically contains a dye or pigment color. To refresh the pixels on the screen, an electric field is applied in the liquid or gel medium. This electric field is established by applying different voltages across the liquid or gel, with one polarity of voltage attracting the particles to the front surface of the pixel and the other polarity of voltage attracting the particles to the back surface of the pixel. When the electric field is established, the particles will move in the liquid or gel according to their charged nature. The positively charged particles will move towards the negative electrode and the negatively charged particles will move towards the positive electrode. This shifting process causes the particles to migrate from one location to another, thereby changing the color state of the pixel. The positions of particles at the positions of all pixels can be controlled by adjusting the distribution of the electric field on the whole display screen, so that the image refreshing is realized. After changing the position of the particles they will scatter or reflect light, creating a different color state, forming a new image.
The embodiment of the application discloses an image display refreshing method of an electrophoretic display screen, and referring to fig. 1, the method comprises the following steps:
step S101: and acquiring multi-frame images which need to be continuously displayed on a preset screen.
In the above steps, the internal memory of the electrophoretic display screen stores multi-frame images to be displayed.
Step S102: and determining the image similarity of a first image and a second image, wherein the first image and the second image are any two adjacent frames of images in the multi-frame images, and the second image is the next frame of image of the first image.
In the above step, determining the image similarity between the first image and the second image specifically includes: acquiring a first number of blocks of pixels of a second image; determining a second number of the plurality of identical pixel blocks in the second image; and obtaining the image similarity according to the ratio of the second quantity to the first quantity.
Specifically, two adjacent frames of images of any two frames of the acquired multi-frame images need to be compared, a first image is defined as a previous frame of images of the two adjacent frames, a second image is defined as a next frame of images of the two adjacent frames, the first image and the second image are divided into pixel blocks with the same size, and the divided images are used for comparing the pixel blocks at the same position. And comparing the gray values of the pixel blocks at the same positions of the first image and the second image, and determining the pixel blocks as the same pixel blocks if the gray values are smaller than a preset gray threshold value. And counting the number of the same pixel blocks in the second image and the number of all pixel blocks in the second image, and calculating the ratio of the number of the same pixel blocks to the number of all pixel blocks in the second image, wherein the ratio is the similarity of the second image and the first image.
Step S103: judging whether the image similarity is larger than or equal to a preset threshold value, if so, determining a target position on a preset screen, wherein the target position is any one of a plurality of positions of the preset screen.
In the above steps, a preset threshold value is preset, the preset threshold value may be 70%, or may be set according to actual requirements, and when the similarity between the second image and the first image is greater than or equal to the preset threshold value, a target position is selected from the electrophoresis display screen, where the target position may be selected randomly, or may be selected according to a specific rule. The steps firstly judge whether the two frames of images are larger than a preset similarity threshold value, so that visual discomfort caused by partial area refreshing of the two frames of images with large difference when partial refreshing is adopted in a subsequent scheme is prevented. As the human eye is easily aware of the discontinuities between images. When the pixel difference between two frames of images is large, local refreshing may result in some portions of the image changing very significantly, while other portions remain unchanged. Such inconsistent changes can cause visual discomfort because the human eye can notice that certain portions of the image change instantaneously.
After step S103, the method further comprises: and if the image similarity is smaller than the preset threshold value, refreshing the pixel blocks at all positions of the preset screen according to the gray values of all the pixel blocks of the second image.
Specifically, when the similarity between the second image and the first image is smaller than a preset threshold, traversing each pixel block of the second image, extracting a gray value of each pixel block, wherein the gray value is a numerical value used for describing brightness or color shade of the pixel block, the gray value is usually in a range of 0-255 and represents the gray value of a pixel, wherein the gray value of 0 represents that the pixel block is black, the gray value of 255 represents that the pixel block is white, and modifying the gray value of each pixel block displayed on the electrophoretic display screen to be the gray value corresponding to each pixel block on the second image by changing the charge state and the movement of charge molecules of the pixel block on the electrophoretic display screen according to the gray value of each pixel block of the second image.
Step S104: determining a first pixel block and a second pixel block, wherein the first pixel block and the second pixel block are positioned at the target position, the first pixel block is any one pixel block of the first image, and the second pixel block is any one pixel block of the second image.
In the above steps, the first pixel block is a pixel block located at the target position in the first image, and the second pixel block is a pixel block located at the target position in the second image.
Step S105: and judging whether the second pixel block and the first pixel block are the same pixel block or not.
In the above step, determining whether the second pixel block and the first pixel block are the same pixel block specifically includes: acquiring a first gray value of a first pixel block and a second gray value of a second pixel block; determining a gray difference value between the first gray value and the second gray value; determining a corresponding preset gray threshold according to the target position; judging whether the gray difference value is smaller than a preset gray threshold value or not; if the gray difference value is smaller than the preset gray threshold value, determining that the second pixel block and the first pixel block are the same pixel block.
In one possible embodiment, before determining the corresponding preset gray threshold according to the target position, the method further includes: determining a first position and a second position of a preset screen, wherein the first position and the second position are any two positions in a plurality of positions of the preset screen;
determining a first distance between the central position of the preset screen and the first position and a second distance between the central position of the preset screen and the second position; according to a preset corresponding rule, a first gray threshold corresponding to the first distance and a second gray threshold corresponding to the second distance are determined, wherein the preset corresponding rule is a corresponding rule of different positions of a preset screen and the gray threshold, the first distance is smaller than the second distance, and the first gray threshold is smaller than the second gray threshold.
