A projection system includes a light source, a reflective phase modulator, a display and a projection lens. The light source is configured to emit a first light. The reflective phase modulator is configured to modulate phase of the first light to form a second light. The display is configured to receive the second light. The display is located between the projection lens and the reflective phase modulator.

Projection system having phase modulator

The projection device includes a light source, a liquid crystal on silicon (LCoS) panel, and a circuit. The circuit is configured to obtain a target image including a target pattern, and generate two content images. Each content image includes a duplicated pattern of the target pattern, and the duplicated patterns are off-axis shifted to the same coordinate when performing a computer-generated hologram (CGH) algorithm, so as to generate a phase image. The LCoS panel is driven according to the phase image to display a reconstructive image at a reconstructive distance.

Projection device and method with liquid crystal on silicon panel

A head mounted display (HMD) apparatus is provided. The HMD apparatus includes a first lens, a second lens, a first micro-display disposed on the first lens, a second micro-display disposed on the second lens, a first light source, a second light source, and an eyeglass frame. A first side of the first micro-display corresponding to a first rubbing alignment processing direction and a first side of the second micro-display corresponding to a second rubbing alignment processing direction are symmetric with respect to a center line of the eyeglass frame between the first lens and the second lens. A first incident light emitted by the first light source is obliquely emitted from the first side of the first micro-display toward the first micro-display and a second incident light emitted by the second light source is obliquely emitted from the first side of the second micro-display toward the second micro-display.

Head mounted display apparatus

A liquid crystal on silicon (LCOS) display panel with reducing fringe effect is provided herein. The liquid crystal on silicon display panel includes a common electrode, a semiconductor substrate having a plurality of pixel electrodes and control electrodes, a passivation layer on the pixel electrodes and a part of the semiconductor substrate, an anti-reflection coating (ARC) layers on the control electrodes, a transparent substrate on the semiconductor substrate, and a liquid crystal layer between the transparent substrate and the semiconductor substrate, wherein each of the control electrodes is disposed between and isolated with two adjacent ones of the pixel electrodes.

Liquid crystal on silicon display panel with reducing fringe effect

The present invention is directed to methods and devices to increase the brightness of images in display devices. A white signal component is generated according to an input color signal, comprising primary signal components Red, Green and Blue. The generated white signal component and the primary signal components will be manipulated by methods and devices disclosed in the invention to generate adjusted primary signal components. Then the white signal component and the adjusted primary signal components will form a display signal for displaying brightness controlled images. Compared with the input color signal, the brightness of the display signal is increased while the color saturation thereof is almost kept.
