Embodiment Construction

[0049] Please refer to " figure 1 ” shows a display device 100 proposed in the first embodiment of the present invention, which is installed with a program code to execute a display method for accelerating update screens. The display device 100 has a display panel 110 , an operation interface 120 , a controller 130 , and a memory module 140 .

[0050] Such as" figure 1 "," Figure 2A "and" Figure 2B ”, the display panel 110 may be a display panel with a low frame update rate, such as an electrophoretic display panel (electronic paper), a grayscale liquid crystal display, but not limited thereto. The display method of speeding up updating the picture is used to drive the display panel 110 to display a picture and update the picture quickly.

[0051] The operation interface 120 can be a combination of keys, multi-directional keys, or a touch interface, and is used for operations to generate screen operation commands.

Abstract

A method for accelerating speed of refreshing image frame is used for driving a display-panel to display and refresh an image frame rapidly. According to the method, the first step is to extract a digital content and generate the image frame according to the digital content, so as to drive the display-panel to display the image frame. A partial refresh area is defined on the image frame, and a partial image frame rather than the entire image frame is refreshed, so as to accelerate the speed of refreshing the image frame. Optionally, a number of gray levels of the partial refresh area are reduced, so as to accelerate the speed of refreshing the image frame. At least one screen operation command is received, partial refresh content is extracted from the digital content according to the screen operation command, and a displayed content in the partial refresh area is refreshed.

Description

technical field [0001] The present invention is related to the picture updating of the electronic paper, in particular to a display method for accelerating the updating of the picture. Background technique [0002] Using electrophoretic display panels (e-paper), such as e-books (E-Book) and e-readers (E-Reader), its main advantages are the reading effect similar to paper printing and very low power consumption, so it is suitable for long-term reading. When the power of the electrophoretic display panel is cut off and the power is turned off, the last displayed picture can still be saved and will not disappear with the power off. [0003] In the image updating step of the electrophoretic display panel (electronic paper), the image of each pixel of the image is completely cleared to blank by using the control electrode, and then the color scale (or gray scale) of each pixel is updated one by one with new image data. It takes a considerable amount of time for each pixel to tra...
