Abstract: A display apparatus having a display panel, a humidity DETECTION method thereof and a GAMMA curve calibration method are provided. A humidity detection method and a gamma curve calibration method for the display panel of the display apparatus are also provided. The humidity detection method for the display panel includes: displaying a test pattern via the display panel; projecting an incident light to the test pattern of the display panel via a light source to generate a diffraction light; and detecting the diffraction light via a light detector to obtain a humidity information of the display panel. Therefore, a gamma setting of the display panel may be adjusted via the humidity information of the display panel.

Abstract: A holographic display system including a first spatial light modulator panel and a second spatial light modulator panel is provided. The first spatial light modulator panel is configured to receive a first light with a first color, and generate a first diffracted light with the first color. The second spatial light modulator panel is configured to receive a second light with a second color and a third light with a third color, and respectively generate a second diffracted light with the second color and a third diffracted light with the third color. The first color, the second color, and the third color are different colors, and the first diffracted light, the second diffracted light and the third diffracted light form holographic images. A method for generating holographic images is also provided.

Abstract: A head-mounted display apparatus includes a display, a couple-in optics module and a couple-out optics module. The display is arranged for displaying at least an image. The couple-in optics module is arranged for receiving the image from the display and directing the received image to another direction. The couple-out optics module is arranged for receiving the directed image from the couple-in optics module to generate an output image directly to a human eye when a user wears the head-mounted display apparatus. In addition, an aspect ratio of the image generated from display is different from an aspect ratio of the output image.

Abstract: 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.
