Next‐generation mobile LCDs with in‐cell retarders

In-cell retarders can be a major breakthrough for mobile LCDs. When a patterned in-cell retarder replaces the external retarders on transflective LCDs, brighter and thinner transflective LCDs with lower power consumption and wider viewing angle can be obtained. Additionally, when in-cell retarders are applied in reflective LCDs, the thickness of the LCD is considerably reduced without affecting the optical performance of the reflective LCD. This paper presents the technology needed to make in-cell retarders and the performance of reflective and transflective LCDs with in-cell retarders.
