Description

Driving method of electronic paper display

technical field

The present invention relates to a driving method of a display, and in particular to a driving method of an electronic paper display.

Background technique

In the technology of the electronic paper display, the electronic paper has a plurality of particles, and each particle represents a pixel of the display. Such particles are, for example, microspheres or cubes. When the particles are subjected to an external voltage (such as positive or negative voltage), the state of the particles will be changed in the future to display black or white on the electronic paper display.

For example, when the particles are in the highest stable state, the gray scale value of these particles is 255 and appear black. When the particles are in the lowest stable state, the grayscale value of these particles is 0 and appears white. When the particles are in the intermediate steady state, the grayscale values of these particles are between 0 and 255, and present different degrees of gray. When the particles of each pixel are driven to different gray levels, all the particles will present a picture. When the electronic paper display wants to change the picture, it is necessary to change the grayscale values of all particles again.

Please refer to FIG. 1 and FIGS. 2A-2E . FIG. 1 is a flow chart of the driving method of the electronic paper display in the first embodiment, and FIGS. 2A-2E are schematic diagrams of steps in FIG. 1 . The electronic paper display uses a plurality of pixels to display frames sequentially, for example, changing the first frame 100 (shown in FIG. 2A ) to the second frame 200 (shown in FIG. 2E ). Wherein, the grayscale value of each pixel is, for example, between 0˜255. In this embodiment, when the pixels are in the highest steady state, the grayscale value of these pixels is 255, and they appear black. When the pixels are in the lowest steady state, the grayscale value of these pixels is 0 and appears white. When the pixels are in the intermediate steady state, the grayscale values of these pixels are between 0 and 255, and present different degrees of gray.

Taking the first picture 100 in FIG. 2A as an example, some areas of the first picture 100 are gray, and the area A is larger than the first predetermined gray scale value (for example, 120). In the icon, gray is represented by cross-hatch dots.

Taking the second picture 200 in FIG. 2E as an example again, some areas of the second picture 200 appear gray, and the area B is larger than the first predetermined gray scale value.

First, in step S101 , as shown in FIG. 2A , the electronic paper display displays a first frame 100 .

Next, in step S102 , as shown in FIG. 2B , the electronic paper display drives the pixels (that is, the area A) with a greater than the first predetermined grayscale value in the first frame 100 (shown in FIG. 2A ) to the highest steady state. That is to say, the pixels in the area A that are larger than the predetermined grayscale value appear black in this step. In the icon, black is represented by a slash.

Then, in step S103 , as shown in FIG. 2C , the electronic paper display drives the pixels (that is, the area B) whose gray scale value is greater than the first predetermined gray scale value in the second frame 200 (shown in FIG. 2E ) to the highest steady state.

Next, in step S104 , as shown in FIG. 2D , the electronic paper display drives all pixels to the lowest steady state. In other words, the entire picture appears white.

Then, in step S105 , as shown in FIG. 2E , the electronic paper display displays a second frame 200 .

According to the above flow chart, the pixels corresponding to the region A or region B are driven to the highest steady state, and all the pixels are driven to the lowest steady state. In this way, the pixels corresponding to the area A are driven to the highest stable state and the lowest stable state, so that the pixels corresponding to the area A are activated without leaving residual images. The pixels corresponding to the area B are also activated, and can be precisely displayed with different grayscale values.

In this embodiment, the driving method of the electronic paper display first executes step S104, and then executes steps S102 and S103. That is to say, in this embodiment, all pixels are first driven to the lowest steady state (as shown in FIG. 4B ), and then some pixels are driven to the highest steady state (as shown in FIGS. 4C-4D ).

In addition, according to the above-mentioned embodiments, although the e-paper displays in the first to third embodiments are described with black and white e-paper displays as examples, the e-paper display may also be a color e-paper display. For example, when the pixel is in the highest steady state, the grayscale value of the pixel is 255, and it appears red, green or blue. When the pixel is in the lowest stable state, the grayscale value of the pixel is 0 and appears black (or white). When the pixel is in the intermediate stable state, the grayscale value of the pixel is between 0 and 255, and it presents different degrees of red, green or blue.
