2results about How to "Large viewing angle" patented technology

A stereoscopic image display device according to an exemplary embodiment of the present disclosure includes a substrate divided into a plurality of sub-pixels each including a light emitting region, a light emitting diode disposed in the light emitting region of the substrate, a color filter disposed above the light emitting diode and overlapping the light emitting region, an optical member disposed above the color filter and including a plurality of high-refractive layers and a plurality of low-refractive layers, an upper side of each of the high-refractive layers being longer than a lower side, the plurality of low-refractive layers being disposed between the high-refractive layers, and an optical lens disposed above the optical member. A wider viewing angle is ensured while maintaining the same resolution to improve the quality of an image in which a user recognizes three dimensions.

A spherical display sound box relates to the field of intelligent products and comprises a base, a controller, a driver, a sound production module and an arc-shaped lamp panel module, the controller, the driver and the sound production module are all mounted on the base, and the controller is in communication connection with the driver and the sound production module at the same time; the driver is in transmission connection with the arc-shaped lamp panel module, and the driver is used for driving the arc-shaped lamp panel module to rotate relative to the base, so that the image of the arc-shaped lamp panel module is displayed in a spherical shape. According to the structural design of the sound box, the visual angle can be increased, the watching experience is improved, and the interactivity is higher.
