Latest Patents

Matsumura's latest patents include an innovative optical system for display apparatus. This system features a light source that emits read light and a reflection-type spatial light modulator. The modulator modulates the incoming read light according to the image written on it. The modulated light is then projected onto a screen via a projection lens, allowing for image display. Additionally, a field lens is strategically placed between the modulator and the screen to enhance the intensity of the modulated light.

Another significant patent is for a display device that produces clear color images with a high contrast ratio. This improved display apparatus includes a spatial light modulator with a photo-conductive layer, a photo-modulator layer, and a dielectric mirror. The device writes color images time-divisionally onto the spatial light modulator and synchronizes the reading lights with the writing process. This innovation ensures that the display device can project color images effectively while maintaining uniform impedance in the photo-conductive layer.
