Problems solved by technology

However, it can be found from actual implementation that the voltage amplitude and frequency of the pulses applied when the existing aging method changes the full screen to a fully transparent state (screen clearing operation) or a foggy light-proof state (scrubbing operation) are fixed, After the pulse is applied, the display screen needs to last for a long time to stabilize the characteristics of the smectic liquid crystal and achieve the purpose of aging. It can be seen that the existing aging methods have the disadvantages of long aging time, low aging efficiency, and poor aging effect. problem to be solved

Abstract

The invention discloses a dynamic aging method for a smectic liquid crystal display. The method comprises the step of repeating full-screen dynamic frosting operation and full-screen dynamic screen clearing operation at least once. According to the method, the frequency and / or voltage amplitude of low-frequency pulse signals applied to row and column electrodes in dynamic frosting operation are / is dynamically changed according to actual conditions, and the frequency and / or voltage amplitude of high-frequency pulse signals applied to the row and column electrodes in dynamic screen clearing operation are / is dynamically changed, so that smectic liquid crystals can rapidly tend to be stable within a short time, and the smectic liquid crystal display can be rapidly aged; compared with a conventional aging method, the method provided by the invention has the advantages that the aging speed is increased, the aging time is shortened, the aging efficiency is improved, and aging effects are improved.

Description

technical field [0001] The invention relates to an aging method for a smectic liquid crystal display, in particular to an aging method for dynamically adjusting voltage amplitude and / or frequency applied to a smectic liquid crystal display, and belongs to the aging field of a smectic liquid crystal display . Background technique [0002] Liquid crystal display is one of the most promising flat panel display devices at present. Traditional liquid crystal displays are passive displays, that is, transmissive displays, which can only be displayed under the condition of an external backlight, but the power consumption of the backlight is the liquid crystal itself. More than hundreds of times the power consumption, very energy-consuming. With the development of liquid crystal technology, various liquid crystal materials emerge in an endless stream, among which the reflective liquid crystal that does not require a backlight has an absolute advantage due to its low power consumptio...
