Electronic paper display device, display device and driving method

Abstract

The method provides an electronic paper display device, a display device and a driving method. The driving method includes obtaining a frame of image data and comparing with a current frame of image data; providing driving waveform data according to comparative results; and providing driving waveforms corresponding with the driving waveform data to drive the display device, allowing the display device to update a current frame of image data to a next frame of image data through a multiframe transition image, wherein for a same frame of transition image for the display device, driving waveforms with same time of duration are provided to each display unit of the display device; for different frames of transition images, the driving waveforms provided to a same line of display units of the display device do not have same time of duration, thereby prolonging charging time of at least part of frames of transition images to reduce displaying of frames of frames of transition images. The driving device can save power by using the driving method.

Description

technical field [0001] The present invention relates to a display device and a driving method thereof, in particular to an electronic paper display device and a driving method thereof. Background technique [0002] Display devices, such as electronic paper display devices, have become more and more popular due to their advantages of flexibility, low power consumption, and high contrast ratio, and have gradually become mainstream electronic products for the public to read information. [0003] Please also refer to figure 1 and figure 2 , figure 1 It is a schematic structural diagram of an electronic paper display device in the prior art. figure 2 yes figure 1 The driving waveform diagram of the e-paper display device shown. exist figure 2 In , the lower part of the waveform (b) is a partially enlarged schematic diagram of the upper part of the waveform (a). Among them, the upper part of the waveform (a) omits the driving clock signal clk (see the lower part of the w...

Problems solved by technology

[0010] For each frame of transition picture, since the data driving circuit 16 applies the same time to the driving waveform of each row of display units 105, that is, the time of the K driving clock signal clk, and the time is relatively short, resulting in the electronic paper display device 1 It is necessary to display more transitional images to update from the current image frame to the next frame image, that is, it is necessary to charge each display unit 105 multiple times, resulting in relatively power consumption of the electronic paper display device 1
