Abstract: A display system includes a content generator, an HMD (Head Mounted Display), and a computing device. The content generator generates image/video information. The HMD obtains a viewing-angle range relative to a user. The computing device is coupled to the HMD. The computing device receives the image/video information and the viewing-angle range. The computing device controls the HMD to display a main screen and a sub-screen according to the image/video information. The computing device adjusts the transparency of the sub-screen by comparing the viewing-angle range with an important-angle range.

Abstract: A display system and a display method are provided. The display system includes an electronic device and a first display device. The electronic device has a first graphics processing unit and a second graphics processing unit. The method includes the following. A first program is executed via the first graphics processing unit of the electronic device and at least one frame corresponding to the first program is generated. The at least one frame is obtained via the second graphics processing unit of the electronic device and the at least one frame is encoded. The frame encoded by the second graphics processing unit is transmitted to the first display device via the electronic device. The encoded frame is decoded via the first display device to display the at least one frame.
