Problems solved by technology

However, nematic liquid crystal itself is a monostable material, and other compounds must be added to form a special structure and achieve the purpose of bistable state. At present, it cannot be extended to multi-stable display.
In recent years, there have been a number of studies on bistable display using smectic liquid crystals, but the driving method still follows the old idea, and the changes are only to improve the molecular chemical structure, or to add ionic impurities to improve its electro-optic rotation. Sexual characteristics, but these can not improve the problem of poor contrast, nor can it have a multi-stable display mode

Embodiment Construction

[0025] Certain terms are used in the specification and subsequent claims to refer to particular components. Those of ordinary skill in the art will appreciate that manufacturers may refer to the same component by different terms. This description and subsequent patent applications do not use the difference in name as a way to distinguish components, but use the difference in function of components as a basis for distinction. The "comprising" mentioned in the entire specification and subsequent claims is an open-ended term, so it should be interpreted as "including but not limited to", which will be described here first.

[0026] Please refer to Figure 1 to Figure 3 , Figure 1 to Figure 3 It is a schematic diagram of a multi-stable liquid crystal display according to the first embodiment of the present invention. Such as figure 1 As shown, the multistable liquid crystal display 10 of this embodiment includes a first substrate 100 , a second substrate 102 , a first electr...

Abstract

The invention relates to a multi-steady state display and a method. The display comprises a first substrate, a second substrate, a first electrode, a second electrode and a liquid crystal layer, wherein the first substrate is parallel to the second substrate; the first electrode is arranged on the first substrate; the second electrode is arranged at the side of the second substrate, facing to the first substrate; and at least one of the first electrode and the section electrode comprises a grid electrode; and the liquid crystal layer contains smectic liquid crystal molecules. The invention adopts a special electrode design, effectively improves the display contrast ratio and also has the multi-steady state display effect.

Description

technical field [0001] The invention relates to a multi-stable liquid crystal display, in particular to a multi-stable liquid crystal display with a special electrode design. Background technique [0002] Due to the advantages of light, thin, short, and small, liquid crystal displays have been used in the past two decades, such as twisted nematic (TN) liquid crystal displays, super twisted nematics (STN) Liquid crystal displays have gradually become mainstream products of display devices. [0003] However, the above-mentioned liquid crystal displays are all monostable display modes, which means that the liquid crystal molecules can only exhibit a single stable state. The display must apply a voltage to drive the liquid crystal molecules to twist, and the liquid crystal molecules will return to their single stable state when the voltage is removed. Therefore, the monostable display must continuously apply voltage to maintain the image to be displayed, so there is a problem o...
