Problems solved by technology

[0006] Existing display panels require electrodes to drive cholesteric liquid crystals to undergo state changes to achieve display. However, the saturation voltage of cholesteric liquid crystals is generally above 40V, so driving cholesteric liquid crystals requires a relatively large driving voltage, which is difficult to realize.

Abstract

The invention discloses a display panel and a display control method thereof. The display panel comprises a backlight source, a first substrate and a second substrate arranged oppositely, a cholesteric liquid crystal positioned between the first substrate and the second substrate, and a first ECB (electronically controlled birefringence) liquid crystal box positioned between the cholesteric liquid crystal and the backlight source. The backlight source emits incident light with wavelength equal to pitch of the cholesteric liquid crystal, and the incident light is incident on the cholesteric liquid crystal via the first ECB liquid crystal box. Liquid crystal molecules in the first ECB liquid crystal box are in two arrangement mode under the action of an electric field, one arrangement mode enables the incident light to have polarity identical to that of the cholesteric liquid crystal after passing the first ECB liquid crystal box, and the other arrangement mode enables the incident light to have polarity opposite to that of the cholesteric liquid crystal after passing the first ECB liquid crystal box. By the display panel and the display control method thereof, display control of the display panel can be realized without high driving voltage, and implementation is simple.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display control method thereof. Background technique [0002] Cholesteric liquid crystal has a unique bistable property, which has attracted more and more attention from the industry. [0003] The cholesteric liquid crystal is in a hometropic texture state (Hometropic Texture) under the action of an electric field, which is called the H state. When the cholesteric liquid crystal is in the H state, the light incident on its surface can be completely transmitted. In the absence of an electric field, the cholesteric liquid crystal is in a planar texture state (Planar Texture), called the P state. At this time, if light with a wavelength equal to the pitch of the cholesteric liquid crystal is incident on the surface of the cholesteric liquid crystal , the cholesteric liquid crystal will exhibit selective reflection characteristics, that is, the left-ha...
