Cholesteric liquid crystal (CLC) displays have the capability to switch between the planar (P) state and the focal conic (FC) state by applying voltage. In the P state, the periodic helical arrangement of liquid crystal molecules causes Bragg reflection, resulting in a bright state. When voltage is applied to tilt the liquid crystal, the helical structure assumes a disordered arrangement, entering the FC state. In this state, incident light does not reflect but passes through the liquid crystal structure and is absorbed by the absorbing layer, resulting in a dark state. In traditional CLC display technology, there are optical issues that need to be addressed regarding bright and dark states. Differences in the helical arrangement under the P state can affect overall reflectance and viewing angle for the bright state. Using the FC state as the dark state may also generate certain backscatter, diminishing the dark state effect. Additionally, in CLC full-color display panels, multiple layers of stacked structures may severely impact the contrast. Our company has been deeply involved in CLC display technology for decades, possessing extensive experience and patented technology.
