Abstract: A light source module includes a light source and a light guide plate. The light guide plate has a light entrance surface, a light exit surface, and a bottom surface. The light entrance surface faces the light source and is located between the light exit surface and the bottom surface. The bottom surface is opposite to the light exit surface and has a plurality of microstructures. The microstructures are a plurality of ridge-shaped microstructures formed in the light guide plate. Each of the microstructures includes a light-facing surface, and a first included angle between the light-facing surface and the bottom surface is 30 degrees to 70 degrees.

Abstract: A touch feedback device includes an optical imaging module, an air supplying module, a sensing module, and a signal processing module. The optical imaging module generates a first floating image. The air supplying device forms an airflow field at the outline and/or around the first floating image. The sensing module is configured to sense the change of the airflow field, including the amount of airflow, the air pressure or the speed of airflow caused by the detected object to correspond to a position information. The signal processing module is configured to determine when the position information is inside the preset trigger area of the first floating image outline area, generates at least one feedback command, wherein the at least one feedback command is sent to the optical imaging module to let the optical imaging module generate a second floating image that is different than the first floating image.

Abstract: A device and a method for generating floating images are provided. An optical imaging module generates a first floating image. A sensing module sends a detection signal to sense first position information of a tested object at a first time point, and generates a feedback signal according to the first position information when the first position information is within a contour range of the first floating image. A signal processing module is electrically connected to the optical imaging module and the sensing module to receive the feedback signal and generate at least one control command and/or at least one feedback command corresponding to the feedback signal. The at least one control command is transmitted to a controller to perform corresponding control on the controller, and the at least one feedback command is transmitted to the optical imaging module, so that the optical imaging module generates a second floating image different from the first floating image.

Abstract: A light field display module including a light field display layer, an adjustment layer, and an image forming layer is provided. The light field display layer is configured to form a light field image beam. The adjustment layer is disposed on a path of the light field image beam, and configured to adjust the light field image beam. The image forming layer is disposed on the path of the light field image beam from the adjustment layer, and configured to change a position of a light field image by changing a direction of the light field image beam. The image forming layer has multiple optical micro-structures.
