Embodiment Construction

[0062] figure 1It is a schematic diagram of the functional modules of the bi-stable active matrix (active matrix, AM) display device 100 of the present invention. The display device 100 includes a bistable active matrix display panel 110 , a scan driver 120 , a data driver 130 and a controller 140 . The bistable active matrix display panel 110 may be an active matrix cholesteric liquid crystal (Ch-LC) display panel or other bistable display medium display panel. The bistable active matrix display panel 110 has a plurality of scan lines Y1 , Y2 , Y3 , Y4 , . . . , Yn and a plurality of data lines X1 , X2 , X3 , X4 , . . . , Xm. The scan driver 120 is coupled to the scan lines Y1˜Yn. The data driver 130 is coupled to the data lines X1˜Xm. The controller 140 is coupled to the scan driver 120 and the data driver 130 .

Abstract

A bi-stable active matrix (AM) display apparatus and a method for driving a display panel thereof are provided. The bi-stable AM display apparatus includes a bi-stable AM display panel, a scan driver, a data driver and a controller. A frame period is divided into a resetting phase and a determining phase. The controller resets pixels on a plurality of scan lines of the bi-stable AM display panel to a homotropic state in the resetting phase through the scan driver and the data driver. The controller writes frame information into the pixels on the scan lines in the determining phase through the scan driver and the data driver.

Description

technical field [0001] The present invention relates to a display device, and in particular to a bi-stable active matrix (AM) display device and a driving method for the bi-stable active matrix display panel. Background technique [0002] The traditional driving method of cholesteric liquid crystal (Ch-LC) display is to first drive each pixel (pixel) into a planar state (planner, or reflective state, bright state), and then according to the updated picture information to maintain the pixel in a bright state or drive it to a focal conic state (focal conic, or non-reflective state, dark state). However, this method takes too long to meet the needs of dynamic video. Contents of the invention [0003] The object of the present invention is to provide a bistable active matrix display device and a driving method for its display panel. It can accelerate the frame update rate of the bistable active matrix display panel. [0004] In order to realize the object of the present inv...
