Embodiment 1
[0031] In one or more embodiments, a liquid crystal writing device voltage control system for realizing partial erasing is disclosed.
[0032] Wherein, the liquid crystal writing device includes: a conductive layer, a bistable liquid crystal layer and a base layer arranged in sequence; the conductive layer is not divided; refer to figure 1 A number of pixel units arranged in an array are integrated on the base layer, and each pixel unit is provided with a pixel electrode and a TFT connected to the pixel electrode; a number of first wires that are supplied with a control voltage for turning on or off the TFT; a plurality of second wires supplying the TFT input voltage;
[0033] refer to figure 1 , the first wire is shared by the pixel units in the same row, and the second wire is shared by the pixel units in the same column. In this embodiment, corresponding to each vertical column and each horizontal row of the pixel unit, a plurality of first wires and a plurality of second...
Embodiment 2
[0055] In one or more embodiments, a liquid crystal writing device voltage control method for realizing partial erasing is disclosed, including:
[0056] Connecting the first wires on the base layer of the liquid crystal writing device to different output terminals of the first VFD drive chipset;
[0057] Connecting each second wire on the base layer of the liquid crystal writing device to different output terminals of the second VFD driving chipset;
[0058] Apply a set voltage to the conductive layer, and control the output voltages of the output terminals of the first VFD driver chip set and the second VFD driver chip set through the main controller, so that the pixel unit covering the partial erasing area on the base layer and the conductive layer The electric field between them reaches the erasing electric field, which can realize partial erasing; while the electric field formed in other regions cannot realize erasing.
[0059] It should be noted that the specific implem...
