Abstract: Disclosed is a monolithic LCD projector, including: a light source, a polarizer provided on a light emitting side of the light source and configured for converting light emitted from the light source into linearly polarized light, an LCD panel provided on a light emitting side of the polarizer and configured for modulating the linearly polarized light according to an image signal to generate modulated light, an analyzer provided on a light emitting side of the LCD panel and separated from the LCD panel and obliqued, the analyzer includes a reflective polarizer and a functional structure, and a lens provided in a reflected light path of the analyzer and configured for projecting the second polarization state light reflected by the reflective polarizer.

Abstract: A bubble maker includes a pressurized container; a liquid storage bag; a bubble generator; and a drainage tube connecting the liquid storage bag and the bubble generator. The liquid storage bag is configured to store a bubble solution. The drainage tube is configured to convey the bubble solution to the bubble generator; and the bubble generator is configured to convert the bubble solution into bubbles. The liquid storage bag includes elastic material and is disposed in the pressurized container. The pressured container includes a fluid inlet so that a fluid is introduced to the pressured container via the fluid inlet to squeeze the liquid storage bag, and thus the bubble solution in the liquid storage bag is squeezed into the bubble generator via the drainage tube.
