Abstract
A novel transflective liquid crystal display (LCD) is provided with a multilayer dielectric film transflector. The dielectric transflector is composed of alternating high and low refractive index dielectric material layers deposited directly on the inner side of the LCD substrate to avoid parallax. The transmittance of the dielectric transflector can vary from approximately 5% to approximately 95% by simply adjusting the individual dielectric layer thickness and the arrangement of layers. The thickness of the 10-layer film is approximately 700 nm, which does not affect the voltage drop on the LC. Two structures of the dielectric film using different positions of the materials of construction are provided and demonstrated. Such a transflective LCD exhibits outstanding features, such as, robust dielectric film, single cell gap, no parallax, and a simple fabrication process.
