— A novel display system, refered to as an LFD (liquid crystal with fine‐pitch light‐source display) is proposed. In an LFD, an auxiliary light source patterned with a fine pitch is attached to a reflective liquid‐crystal display (LCD), and a light shield is formed on the observer's side of the light source. A vertical‐alignment LCD (VA‐LCD) is attached as the reflective LCD, and an organic light‐emitting diode (OLED) is attached as the fine‐pitch light source. An LFD can produce bright, high‐contrast images under any ambient light. A test sample was built and its display characteristics confirmed.
