The invention discloses a light source device for an information display device, and a virtual image type image display device is provided with an optical system. The optical system includes a display panel for displaying an image, a light source device for providing light to the display panel, an optical assembly for receiving image light from the display panel, and an optical element for adjusting the image light captured by the optical system, the optical element is located on one side of the image display surface of the display panel opposite to the optical assembly, the incident position and the incident angle of the image light emitted from the optical element and incident to the optical assembly are adjusted, and the optical system forms an enlarged projection image by receiving the image light emitted by the image display surface of the display panel. By controlling the intensity and diffusion characteristics of the image light emitted by the image display surface of the display panel serving as the image display device, the efficiency of the image light entering the optical assembly is improved, and an amplified projection image is formed.

    本发明公开了一种信息显示装置用光源装置,其虚像方式图像显示装置具有光学系统,该光学系统包括用于显示图像的显示面板、用于向显示面板提供光的光源装置、用于接收来自显示面板的图像光的光学组件以及用于调整光学系统捕捉的图像光的光学元件,其中,光学元件位于和光学组件相向的显示面板的图像显示面一侧,调整从光学元件射出,射入到光学组件的图像光的入射位置和入射角度,光学系统通过接收显示面板的图像显示面发出的图像光形成放大的投影图像。本发明通过控制由做为图像显示装置的显示面板的图像显示面发出的图像光的强度和扩散特性,提高图像光进入光学组件的效率,形成放大的投射图像。
