Problems solved by technology

However, the problem in this regard is how to make the feeling of reading and reading as close as that of using paper? Just "electronic paper" does not constitute a display. As a necessary condition, it also includes ensuring the contrast between the image part and the non-image part, that is, the legibility, the ability to eliminate or rewrite the original graphics, low energy consumption for image writing and storage, etc.

Embodiment Construction

[0033] In order to enable a further understanding and understanding of the purpose of the present invention, the characteristics and effects of the driving method, embodiments are now given in conjunction with the accompanying drawings, and detailed descriptions are as follows.

[0034] The method in the prior art, such as US Patent Publication No. 20060050050, must be driven sequentially according to the time required for the gray scale of each pixel. The total driving time of the existing method is the total driving time of all pixels plus the initial whitening time. The driving sequence of the electrophoretic display is as described in US Patent Publication No. 20060077190. Refer to figure 2 The sequential driving schematic diagram of the control circuit (15) controls the gate driver IC (11) and the source driver IC (12). The gate driver IC (11) is responsible for informing the transistor on the row of the display panel (14) to turn on or off. The source driver IC (12) inputs t...

Abstract

The invention discloses a method for driving an active electrophoretic display device. The active electrophoretic display device comprises a plurality of sub-pixels which are arranged in a matrix form for sequentially driving a single pixel or a plurality of pixels. The method comprises the following steps: inputting a picture, acquiring the grey-level value of each pixel, and sequentially driving the pixels; performing sequential driving for the first time by applying a driving voltage with respect to all pixels on a panel so as to convert all pixels to one of two extreme grey-level values; and performing sequential driving for multiple times according to a defined bit resolution by applying a driving time and a driving voltage which are required to convert the previous level grey-level value to the next level grey-level value with respect to all pixels with the grey-level values higher than the next level grey-level value. The method can accelerate the picture display of the electrophoretic display device.

Description

Technical field [0001] The present invention relates to an active electrophoretic display driving method, in particular to a technology applied to reduce the response time of updating images of the electrophoretic display, thereby accelerating the display speed of the electrophoretic display. Background technique [0002] The so-called electrophoretic display (electronic paper), different from our common fiber paper, is a kind of "conductive" "polymer" material containing many "microspheres" (capsules) (1), and its appearance and characteristics are similar to those of ordinary paper. Same quality, softness and repeatable display of data. In the electronic paper technology, the size of the tiny sphere represents the size of the display pixel (Pixel), and the characteristic of the tiny sphere is that it will be driven by an external voltage to change its state. Such as the electronic ink display mentioned in US Patent Publication No. 20060050050. The conductive feature of electron...
