Method, device and storage medium for eliminating afterimage

Abstract

Embodiments of the present application provide a method, device, and storage medium for eliminating image sticking, which are applied to optical communication products or components including LCOS panels, and are used to eliminate image sticking caused by long-term fixed display images of the LCOS panels. The method includes: detecting that the LCOS panel is in a display state; dynamically changing the driving voltage of the LCOS panel to dynamically adjust the picture corresponding to the LCOS panel, wherein the picture after dynamic adjustment has the same display effect as the picture before dynamic adjustment. The embodiment of the present application can eliminate the afterimage phenomenon when the product using the LCOS technology works for a long time.

Description

technical field [0001] The embodiments of the present application relate to optical communication technologies, and in particular, to a method, an apparatus, and a storage medium for eliminating image sticking. Background technique [0002] With the continuous development of optical communication technology, liquid crystal on silicon (LCOS) technology is produced. Among them, LCOS technology, also known as silicon crystal photonics technology, liquid crystal on silicon technology, etc., is a technology combining semiconductor technology and liquid crystal display (LCD). Because LCOS technology has the advantages of high resolution, low price, and more energy saving and environmental protection, LCOS technology shows strong development potential in the field of display technology. However, LCOS technology still has a defect that cannot be ignored: when products using LCOS technology, such as wavelength selective switches (WSS), work in one state for a long time, that is, the...

Problems solved by technology

However, LCOS technology still has a defect that cannot be ignored: when products using LCOS technology, such as wavelength selective switches (wavelength selective switch, WSS), work in one state for a long time, that is, the same wavelength is maintained in a certain direction for a long time At this time, the driving voltage of the liquid crystal alignment layer maintains a state for a long time. At this time, due to the characteristics of the liquid crystal molecules in the liquid crystal alignment layer, the product will have image sticking when switching screens.

[0004] However, for the application of LCOS technology, the impact of residual image belongs to the influence of the online status of the product. Therefore, the above-mentioned solution to eliminate the phenomenon of residual image after shutdown is not applicable to products using LCOS technology.
