Aging method of smectic-phase liquid crystal display screen

Abstract

The invention discloses an aging method of a smectic-phase liquid crystal display screen, which comprises the steps of: a. respectively loading a pair of low-frequency pulse signals to each row of electrodes and each line of electrodes within first preset time, and after set time, respectively loading a pair of high-frequency pulse signals to each row of electrodes and each line of electrodes within second preset time; and b. repeating the step a at least one time, wherein in the step a, the pair of low-frequency pulse signals have opposite phases and identical or different voltage amplitude values; and the pair of high-frequency pulse signals have opposite phases and identical or different voltage amplitude values. The voltage amplitude value and frequency of voltage signals applied to each row and each line as well as the time interval for repeatedly executing the step a can be flexibly controlled according to actual demands, so as to adjust the aging intensity and achieve optimal aging effect. By adopting the method, the drive characteristics of the smectic-phase liquid crystal material in the display screen trends to be stable, instability and diversity of the display screen are avoided, and the display quality of the display screen is guaranteed.

Description

technical field [0001] The invention relates to an aging method for a display screen, in particular to an aging method applied to a smectic liquid crystal display screen. 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 consumption characteristics. Smectic liquid crystal display (also known as smectic liquid crystal display), with its unique film surface characterist...

Problems solved by technology

[0004] However, when actually driving the display, it is found that due to the influence of factors such as the initial deflection state of the smectic liquid crystal molecules and the characteristics of the smectic liquid crystal molecules, even if the same driving method and driving voltage signal are used in the same environment Driving and displaying smectic liquid crystal displays does not necessarily make all smectic liquid crystal displays achieve the same display state, but there will be differences in light transmittance, and even full-screen inconsistencies, that is, In other words, for the deflection of the smectic liquid crystal molecules in the display screen, it is not how much energy is stably input, and where the liquid crystal molecules can deflect, which is affected by various factors, and the deflection of the liquid crystal molecules will appear instability and variability
