Problems solved by technology

[0006] At present, the GC mode is generally used to display pictures on EPD e-books, and the displayed colors are relatively rich, but it is very slow when displaying moving pictures, and there is a phenomenon of freezing. Although the display speed is faster when using A2 mode, it can only Displays black and white and the displayed picture is blurry

Embodiment Construction

[0020] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0021] see figure 1 , is an execution flowchart of a method for fast moving and displaying pictures of an EPD in the first embodiment of the present invention. A method for fast moving and displaying pictures of an EPD, comprising:

[0022] Step S1, determine whether the width of the zoomed picture is greater than the width of the EPD screen or whether the height of the scaled picture is greater than the height of the EPD screen, if so, perform step S2;

[0023] Step S2, judging whether an instruction to move a picture from the touch screen is received;

[0024] Step S3, when it is determined that the touch screen receives the instruction to move the picture, convert the color image data of the scaled picture into 256-grayscale black-and...

Abstract

The invention discloses a method for rapidly moving an EPD (Electronic Paper Display) and displaying pictures. According to the method and a device for rapidly moving the EPD (Electronic Paper Display) and displaying pictures disclosed by the invention, moving pictures undergo image data conversion, and are displayed by adopting an A2 mode, so that the display speed is increased; and moreover, picture data are converted by adopting a Floyd-Steinberg dithering algorithm, so that images become clearer, and moving pictures are displayed more clearly and rapidly on an EPD screen. The invention further discloses the device for rapidly moving the EPD and displaying pictures.

Description

technical field [0001] The invention relates to EPD display technology, in particular to a method and device for fast moving and displaying pictures of EPD. Background technique [0002] Electrophoretic display technology (EPD), also known as electrophoretic display, is a display technology developed earlier in paper-like displays. It uses colored charged balls to move in a liquid environment with an external electric field to present different color display effects. It represents Manufacturers include E-Ink and Sipix. [0003] What is electrophoresis technology? Literally means "swimable under a certain voltage", the display works by the movement of electric ions immersed in a transparent or colored liquid, that is, by flipping or flowing tiny particles to brighten or darken pixels , and can be fabricated on glass, metal or plastic substrates. The specific technique is that titanium dioxide particles with a diameter of about 1 mm are dispersed in hydrocarbon oil, black d...
