Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] In order to facilitate the understanding of the technical solutions provided by the embodiments of the present invention, an electrochromism device (English: Electrochromism Device, ECD for short) display panel is firstly introduced. Such as figure 1 As shown, a conventional ECD display panel includes several pixel units 1 and driving circuits 2 . A number of pixel units 1 can be arranged in a matrix, and a specified voltage signal is input to each pixel unit 1 at a specified time through the drive circuit 2, so that each pixel unit 1 displays an image under the action of the driving voltage. In this way, the ECD display panel can display a Frame by frame image. The working process of the ECD display panel is well known to tho...

Abstract

The invention discloses a display method and device and belongs to the field of electrochromic devices. The method includes the steps that gray scale data of a current frame image are obtained, and the gray scale data of the current frame image comprise gray scales of the current frame images of a plurality of sub-pixel units; the gray scale of the current frame image of the first sub-pixel unit in the sub-pixel units is compensated, the gray scale data of the compensated current frame image are obtained, and the first sub-pixel unit is a sub-pixel unit with the gray scale of the current frame image being different from the gray scale of a prior frame image; the current frame image is displayed according to the gray scale data of the compensated current frame image. The device comprises an acquisition module, a compensation module and a display module. The display method and device eliminate the influences of difference of display brightness due to the fact that the first sub-pixel units correspond to different transmittances in a developing stage and a color fading stage, then solve the problem that the difference of display brightness of an ECD display panel, and improve the display effect of the ECD display panel.

Description

technical field [0001] The invention relates to the field of electrochromic devices, in particular to a display method and device. Background technique [0002] Electrochromism (English: Electrochromism, EC for short) refers to a special phenomenon in which some materials produce reversible changes between the color-causing state of low transmittance and the achromatic state of high transmittance under the action of an external electric field. At present, electrochromism devices (English: Electrochromism Device, ECD for short) based on EC technology have been widely used in lighting control of intelligent buildings, large-area outdoor digital and graphic displays, adjustable reflectivity rearview mirrors of automobiles, aircraft Color-changing windows and other fields. [0003] A conventional ECD display panel includes a number of pixel units made of EC materials and a driving circuit for supplying driving voltages to the pixel units. Each pixel unit displays a color under...
