Abstract

The invention relates to the technical field of liquid crystal displaying, in particular to a liquid crystal membrane writing board with a wide temperature range and high contrast and a preparation method. The liquid crystal membrane writing board with the wide temperature range and the high contrast comprises a PET transparent thin membrane with a single side coated with ITO, a liquid crystal thin membrane and a PET non-transparent black thin membrane with a single side coated with ITO which are successively connected from top to bottom; one side of a conducting layer of the PET non-transparent black thin membrane with the single side coated with the ITO is coated with an insulating layer. Normal writing and displaying can be achieved on the liquid crystal membrane writing board with thewide temperature range and the high contrast at the temperature of -20-90 DEG C, and the liquid crystal membrane writing board almost can meet writing requirements in any normal natural environment.

Description

Technical field: [0001] The invention relates to the technical field of liquid crystal display, in particular to a writing board with wide temperature range and high contrast liquid crystal film and a preparation method thereof. Background technique: [0002] With the development of liquid crystal display technology, liquid crystal film writing board is gradually developed. Due to the high reflective brightness, high contrast, low power consumption, wide viewing angle, environmental protection, energy saving and emission reduction of the liquid crystal film writing board, it can meet the writing requirements of writing boards of various sizes, so the liquid crystal film writing board is gradually replacing the traditional writing board . [0003] Due to the narrow temperature range of the current liquid crystal film writing boards on the market, the writing boards can only have ideal writing effects in a specific temperature range, which limits the use of liquid crystal fil...
